Introduction:
The word textile is only applied to woven fabrics, now generally to fibers,
yarns, or fabrics. The term textile originates from the latin verb ‘TEXERE’
means to weave but, as the Textile Institute’s Definitions glossary explains, it
is now
“a general term applied to any manufacture from fibres, filaments or yarns
characterized by flexibility, fineness and high ratio of length to thickness”.
Textiles, especially fabric are the fundamental component of a readymade
garment, because it is the basic raw material of a garment. So it is important
to know the manufacturing sequence of fabrics from fibre. The quality product
is the main gole at present time. Without the knowledge of textile
manufacturing i.e. fibre, yarn, and fabrics it is impossible to maintain the
quality of a garment.
So the definition of textile is as follows-
Textile:
A Textile was originally a woven fabric but now the term textile and its plural
textiles are also applied to fibers, filaments, yarn and most products for which
these are a principle raw material. The product includes threads, cords, ropes,
braids woven, knitted, non-woven fabrics, nets, household textile, geo-textile,
medical textiles etc.

Fibre:
Any substance, natural or manufactures, with a high length to width ratio and
with suitable characteristics for being processed into fabric; the smallest
component, hair like in nature, that can be separated from a fabric.
A unit of matter characterized by flexibility, fineness and higher ratio of length
to width is called fibre.
Generally the length should be 500 to 1000 times longer than width. It should
have certain properties also like sufficient strength, length, fineness, elasticity,
crimp, friction, power to react with acid and alkalis and the power to protect
the effect of biological agents etc.
Example: Cotton, Jute, Linen, Nylon etc.
There are two kinds of fibre-
1. Natural fibre: Cotton, jute, silk etc.
2. Man made fibre: Nylon, polyester etc.
Filament:
A fibre of indefinite length which is made by artificial way called filament.
There are two kinds of filament-
1. Mono filament: 1-15 holes in spinneret.
2. Multi filament: 10-100 holes in spinneret (apparel)
100-1000 holes in spinneret (industrial use)

The history of fibers is as old as human civilization. Traces of natural fibres
have been located to ancient civilizations all over the globe. For many
thousand years, the usage of fiber was limited by natural fibers such as flax,
cotton, silk, wool and plant fibers for different applications.
Fiber history can be divided into natural fibers and man-made or chemical
fibers. One of the most used natural fibers since ancient times and a glimpse
at their brief history have been listed here.

FIBER HISTORY

NATURAL FIBERS
1. Flax:
 The recorded usage of Flax can be dated back to 5000 BC and it is
considered to be the oldest natural textile fiber.
 There has been reported usage of fine linen used in Egyptian pharaohs
and tombs.
 One of the largest producers of Flax today include the Soviet States,
Poland, Germany, Belgium and France while one of the key exporters are
Northern Ireland and Belgium.
2. Cotton:
More than 1,300 years ago, it is recorded as a singular fact that an emperor
named Ou-ti, wore on the occasion of his accession to the throne of China, a
cotton robel.
 Earliest use of cotton has been estimated between 3,000 BC to 5,000 BC.
 It is recorded to have been worn by Egyptians prior to 2,500 BC. The
invention of the cotton gin in 1793 revolutionized the processing of cotton.
 During 1884, the development of the power loom brought about significant
improvements and variations to cotton fabrics.
Major producers: United States, Soviet States, China and India. Lessor
producers include Pakistan, Brazil, Turkey, Egypt, Mexico, Iran and Sudan.

3. Wool:
In the tombs and ruins of Egypt, Nineveh, and Babylon, in the barrows of early
Britons, and among the relics of the Peruvians, fragments of woolen fabrics
have been found.
 The Romans began to improve their flocks as early as 200 BC, that later
became the progenitors of the popular Spanish Merino sheep.
 The dated usage of wool goes back to 3,000 BC and it is known to have
been used by people of the late stone age.
 During the 18th
century, England became the great wool-producing country
of Europe, and wool was the staple of its industry until cotton began to
overshadow it.
 In 1788, the first factory in America using water power to weave wool was
established at Hartford, Conn.
There are 40 different breeds of sheep, which produce approximately 200
types of wool of varying grades. The key producers of wool are Australia, New
Zealand, Soviet States, China, South Africa, and Argentina.
4. Silk:
Silk production and its roots in textile history is ancient, variegated and
unknown to many.
 Pliny, the Roman historian, quoted in his Natural History in 70 BC “Silk
was obtained by removing the down from the leaves with the help of
water…”.
 For more than two thousand years the Chinese kept the secret of silk
altogether to themselves.
 It is believed to be discovered by a Chinese princess. It was a guarded
secret that passed through many centuries till it was discovered.
More recent archeological reveal a small ivory cup carved with a silkworm
design predicted to be between 6000 and 7000 years old. Spinning tools, silk
thread and fabric fragments were found from sites along the lower Yangzi
River in China and goes on to unravel the origins of sericulture as being earlier
than recorded in history. There is a story that two monks smuggled seeds of
Fig. Wool fiber.

the mulberry tree and silkworm eggs out of China by hiding them in their
walking sticks. Silk is made from two continuous filaments cemented together
and used to form the cocoon of the silkworm. It is again said that India learnt
of silk culture when a Chinese princess married an Indian prince. The major
producer and exporter of silk is Japan.

MANUFACTURED/MAN-MADE/CHEMICAL FIBERS
In the year 1665, the English researcher Robert Hooke was the first to
describe in his book “Micrographia or some physiological descriptions of minute
bodies” the idea of producing artificial silk from a gelatinous mass.
Starting from then to now, man-made fiber production has reached an
estimate of more than 24 million ton. Used for different applications such as
modern apparel, home furnishings, medicine, aeronautics, energy, industry
and more. Fiber engineers can combine, modify and tailor fibers in ways far
beyond the performance limits of fiber drawn from the silkworm cocoon, grown
in the fields, or spun from the fleece of animals. Listed here are the common
fibres with their brief history and major producers.
1. Rayon:
Rayon was the first manufactured fiber. It was developed in France in the
1890s and originally also called as artificial silk.
 In 1924, the term rayon was officially adopted by the textile industry as
a man-made fiber.
 It is different from most chemical fibers as rayon is not synthetic.
 It is made from wood pulp, a naturally-occurring, cellulose-based raw
material.
 As a result, rayon’s properties are more similar to those of natural
cellulosic fibers, such as cotton or linen, than those of thermoplastic,
petroleum-based synthetic fibers such as nylon or polyester.
By using two different chemicals and manufacturing techniques, four type of
rayons was developed—Regular rayon, High Wet Modulus (HWM) rayon, High
Tenacity Rayon, Cupramonium Rayon. Currently, two major companies
manufacture rayon fiber for U.S markets. British companies manufactures
viscose rayon in short staple lengths and microfibers. Lenzing, based in
Austria, produces viscose rayon, high wet modulus or polynosic rayon,
microfibers, and long filament fibers which are used in linings and dress fabrics
like taffeta. Lenzing is the only company currently manufacturing rayon in the
United States. Overall, rayon is manufactured primarily in Europe and Japan.
Fig. Rayon fiber.

2. Acetate:
The first commercial textile uses for acetate in fiber form were developed by
the Celanese Company in 1924.
 In 1893, Arthur D. Little of Boston invented a cellulosic product called
acetate. He developed it as a film.
 By the year 1910, Camille and Henry Dreyfus started making acetate
motion picture film and different toilet articles in Basel, Switzerland.
 It was during World War I, they built a plant in England to produce
cellulose acetate dope for airplane wings and other commercial products.
 Upon entering the War, the United States invited the Dreyfus brothers to
build a plant in Maryland to make the product for American warplanes.
3. Nylon:
Nylon’s advent created a revolution in the fiber industry. Rayon and acetate
had been derived from plant cellulose, but nylon was synthesized completely
from petrochemicals.
 It established the basis for the ensuing discovery of an entire new world
of manufactured fibers.
 It was in the laboratory of American chemist Wallace Carothers that
Nylon, the miracle fiber was born.
 While working in the laboratories of the DuPont Company on giant
molecules called polymers, Wallace focused his work on a fiber simply
called as “66”, which is a number derived from its molecular structure.
DuPont began commercial production of nylon in 1939. The first testing used
nylon fiber as sewing thread, in the creation of parachute fabric, and also in
women’s hosiery. In February 1939, Nylon stockings were first shown at the
San Francisco Exposition. During the World War II, nylon replaced Asian silk in
parachutes. It also found use in tires, tents, ropes, ponchos, and other military
supplies, and even was used in the production of a high-grade paper for U.S
currency.

4. Acrylic:
In 1944, Acrylic was developed by DuPont and was first commercially
produced in 1950.
 Acrylonitrile, the substance from which acrylic fibers are produced, was
first made in 1893 in Germany.
 It was used as another chemical in research for the DuPont Company.
 A new fiber, acrylic was added to the list of generic names, as DuPont
began production of this wool-like product.
It was at first used for outdoor purposes. While technology has allowed acrylic
to come a long way, and it is now most commonly used in apparel and
carpets. DuPont ceased production of acrylic in 1991, and only a handful of
companies produce acrylic today. The growing demand for acrylic increased in
so do the number of trade names for which acrylic is most known. Pil-Trol is
just one of the many trade names of acrylic and was developed by Monsanto
Chemical Company. It allows for the comfort and easy care of acrylic without
the pilling. Pills are the little that form on fabric when fiber ends break and
migrate to the surface. Pilling is a disadvantage of acrylic, but has been
eliminated by the technology of Pil-Trol. Other trade names that describe
acrylic include:
 Acrilan
 Acrilan Plus
 Biofresh
 Bounce-Back
 Creslan
 CresLoft
 Duraspun
 Fi-lana
 Innova
 MicroSafe
 MicroSupreme
 Salus
 Sayelle
 So-Lara
 Smart Yarns
 Ware-dated
 WeatherBloc
 Wintuck
5. Polyester:
Polyester began as a group of polymers in W.H Carothers’ laboratory, the
inventor of nylon fibers. Carothers was working for DuPont at the time when
he discovered that alcohols and carboxyl acids could be successfully merged to
create fibers.
Polyester was put on the back shelf once Carothers discovered nylon. In 1939,
his work was resumed by a group of British scientists, J.R. Whinfield, J.T.
Dickson, W.K. Birtwhistle, and C.G. Ritchie. In 1941, they successfully created
the first polester fiber called Terylene. In 1946, DuPont bought all legal rights
from them and came up with another polyester fiber which they named
Dacron.
 In 1951, Polyester was first introduced to the Americans.
 It was advertised as a miracle fiber that could be worn for 68 days
straight without ironing and it would still not wrinkle.

In 1958 another polyester fiber called Kodel was developed by Eastman
Chemical Products, Inc. Ever since, the polyester market has been growing.
Since it is an inexpensive and durable fiber, small textile mills emerged all
over US. Polyester reached a constant growth until the 1970s when sales
drastically fell down due to the negative public image that came up during the
late 60s as a result of the infamous polyester double-knit fabric! Today,
polyester is still widely regarded as a “cheap, uncomfortable” fiber, but even
now this image is slowly beginning to change with the emergence of polyester
luxury fibers such as polyester microfiber.
6. Triacetate:
In the year 1901, Arthur Eichengrun and Becker succeed in directly acetylating
cellulose to triacetate at Farbenfabriken , formerly Friedr. Bayer and co.
 In 1954, Celanese launched Amel triacetate filament yarn after
overcoming significant technical barriers.
 The first commercial production of triacetate fiber in the United States by
the Celanese Corporation in 1954.
 Amel is made from triacetate fibres from purified wood cellulose which
has been chemically bonded to acetyl.
 Domestic Triacetate production was discontinued in 1985.
7. Spandex:
Spandex was invented in 1959, and when first introduced it revolutionized
many areas of the clothing industry.
 It is the stretchable fiber of bathing suits and sports clothes, is stronger
and more durable than rubber, its major plant competitor.
 The first U.S commercial spandex fiber production began in 1959 by the
DuPont company.
 Spandex is an elastomeric man-made fiber (able to stretch at least
100% and snap back like natural rubber).
 A well-known trademark for spandex or elastane is Invista’s brand name
Lycra; another trademark (also Invista’s) is Elaspan.
 Current U.S spandex fiber producers: Invista; Bayer Corporation.

8. Polyolefin/Polypropylene:
Polyolefin is a polymer.
 In 1966, polyolefin became the world’s first and only Nobel Prize-winning
fiber due to its unique equalities. It can float and is abrasion-resistant.
 It is a good insulator, dries very quickly and resists deterioration from
chemicals and perspiration.
 It is used mainly in furnishings and high performance active wear. In
1980, the production of polyolefin hollow fiber membranes started.
9. Lyocell:
First produced in the US by Courtaulds Fibers, Lyocell was known by the trade
name “Tencel”.
 The first commercial production of lyocell began in the U.S. during 1993,
by Courtaulds Fibers.
 It is an environment friendly fiber, created from the wood pulp of trees.
 It is processed using a solvent spinning technique in which the dissolving
agent is recycled, reducing environment effluents.

10. Microfibers:
Microfiber was introduced in 1986. Microfibers are a variety of polyester that
has extremely thin filaments. As a synthetic it provides us with control over its
supply. Microfibers is derived using technology and the result is to extrude
extremely fine filaments (less than 1.0 denier) while maintaining all of the
strength, uniformity and processing characteristics expected by textile
manufacturers and consumers.
 Microfiber as the sole constituent of a cloth will wear and shed fiber with
use, so it is best utilized in combination with Nylon.
 It is tough, and can be manufactured to extremely fine tolerances, many
times thinner than other synthetics.
 It is this strength, precision and absolute sheerness as well as its
phenomenal absorbency that give rise to so many applications, including
an amazing ability to clean and dry surfaces.

Yarn:
A product of substantial length and relatively small cross-section consisting of
fibres or filaments with or without twist.
Explanation: Assemblies of fibres or filaments are usually given other names
(tow, sliver, roving). Except in the case of continuous filaments or tape yarns,
any tensile strength processed by assemblies at these stages is generally the
minimum that can hold them together during processing.
Yarn is a long continuous length of interlocked fibres, suitable for use in the
production of textiles, sewing, knitting, weaving, and ropemaking. Yarn can be
made from any number of synthetic or natural fibres.
Twist:
The condition of a yarn or similar structure when the component element have
helical disposition such as results, for instance from relative rotation of the
yarn ends. A yarn may be twisted by down twisting. E.g. ring twisting.
There are two directions of twist-
1. S-Twist and
2. Z-Twist.
1. S-twist:
When the yarn is held in a vertical position, the twist of yarn which is spirals in
the line with the central portion of the letter ‘S’ is known as S-Twist.
YARN DEPARTMENT

2. Z-twist:
When the yarn is held in a vertical position, the twist of yarn which is spirals in
the line with the central portion of the letter ‘Z’ is known as Z-Twist.
Draft:
To reduce the liner density (The quantity of anything distributed along a line
per unit length of line.) of a fibrous assembly by drawing, when drafting the
degree of attenuation calculated either as the ratio of the input to output linear
densities or as the ratio of the surface speeds of the output and input machine
components which bring about drafting.

Yarn count:
Count is a numerical value which expresses the coarseness or fineness
(diameter) of the yarn and also indicates the relationship between length and
weight (the mass per unit length or the length per unit mass) of that yarn.
Types of yarn count:
1. Direct count system (fixed length system): Jute, Hemp, Wool etc.
2. Indirect count system (fixed weight system): Cotton, Worsted, Linen etc.
1. Direct count system:
The weight of a fixed length of yarn is determined. The weight per unit length
is the yarn count i.e. Tex, Denier, Decitex, Kilotex, Militex etc.
Common features of all direct count system are the length of yarn is fixed and
the weight of yarn varies according to fineness. Higher the count, coarser the
yarn.
The following formula is used to calculate the yarn count:
Yarn count (N) =
=
=
Numbering system Unit of length (l) Unit of weight (w)
Tex system 1000 m No of grams (1gm)
Denier, D 9000 m No of gram (1gm)
Decitex, dtex 10,000 m No of gram (1gm)
Militex, mtex 1000 m No of milligram (1mg)
Kilotex, ktex 1000 m No of kilogram (1kg)
Jute count(pounds per
spindle)
14,400 yards No of pounds (lb)(1lb)
YARN NUMBERING SYSTEM:
Sample yarn weight (W)

Definition of the above system:
Tex system :No of grams or weight in grams per 1000 m.
Denier :No of grams or weight in grams per 9000 m.
Decitex :No of grams or weight in grams per 10,000 m.
Militex :No of milligrams or weight in milligrams per 1000 m.
Kilotex :No of kilograms or weight in kilograms per 1000 m.
Jute count :No of lb or weight in lb per 14,400 yards.
For example:
A yarn with 40 tex count indicates that 1000m of yarn weighs 40gm.
A yarn with 200D means 9000m of yarn weighs 200gm.
Problem:
If the weight of 100 yards of jute yarn is 3 ozs, what will be the count?
Solution:
Here,
Sample weight, W = 3 ozs
Unit of weight, w = 1 lb = 16 ozs
Sample length, L = 100 yds
Unit of length, l = 14400 yds
We know,
Jute count (pound per spyndle) = = = 27 spyndle
W l
w L
3 14400
16 100
(Ans)

2. Indirect count system:
The length of a fixed weight of yarn is measured. The length per unit weight is
the yarn count.
Common features of all indirect count system are the weight of yarn is fixed
and the length of yarn varies according to fineness. Higher the count, finer the
yarn.
The following formula is used to calculate the yarn count:
Yarn count (N) =
=
=
Numbering system Unit of length (l) Unit of weight (w)
English cotton count, Ne 840 yards 1 pound (lb)
Metric count, Nm 1000 meters/1km 1 kg
Woollen count (YSW) 256 yards 1 pound (lb)
Woollen count (Dewsbury) 1 yard 1 ounce (oz)
Worsted count, NeK 560 yards 1 pound (lb)
Linen count, NeL 300 yards 1 pound (lb)

Fabric:
A manufactured assembly of yarns that has significant surface area in relation
to its thickness and sufficient cohesion to give the assembly useful mechanical
strength.
Types of fabric:
1. Woven fabric: The fabric which is produced by interlacement of two
sets of yarn is called woven fabric. The two sets of yarns are- a)
warp yarn and b) weft yarn.
2. Knitted fabric: The fabrics which are produced by one sets of yarn by
interlooping is called knitted fabric.
3. Non-woven fabric: Here fabrics are produced by connecting yarn with
gummy bonded materials. It can be done in mechanical, chemical or
thermal ways.
4. Braided fabric: At least three sets of yarn is required. Fabric is
produced diagonal interlacement/interwining/twisting.
WOVEN FABRIC
Warp yarn:
The yarns which lay in vertical direction of cloth and parallel to the selvedge
are warp yarns. They are generally very long.
Weft yarn:
A number of yarns/threads lying at right angles to the warp threads.
Weave:
The pattern of interlacing of warp and weft in woven fabric.
Ends:
Individual warp threads/yarn.
Picks:
Individual weft threads/yarn.

Winding:
Winding is the process of transferring yarns from ring, bobbin, hank etc. into a
suitable package.
It may be electrical or mechanical.
Warp Cone, Cheese, Flanged bobbin.
Weft Cop, Pirn.
Warping:
Winding is a part of total number of ends of a warp in full width on to a back
beam from cone or cheese is known as warping.

Sizing:
The process by which a gelatinous film forming substance in solution or
dispersion, applied normally to warps, generally before weaving to protect
yarns from abrasion in the healds and reed, against each other, to strengthen
them and by addition of oils and fats to lubricate them. Sizing is used for
softening, antiseptic for insects, mildew, breakage, weight, coloring matters.
Drawing-in:
Drawing in is the entering of yarns from a new warp beam into the weaving
elements of a weaving machine, namely drop wires, heald frame and reed,
when starting up a new fabric style.
Tying-in:
After the depletion of a warp beam on the weaving machine, if there will be no
change in design, then the drawing in process needs not be repeated. The
ends of the old warp beam are cut and the ends of the new warp beam are
tied to the corresponding ends of the old beam which is called tying-in
process.
Knotting:
The function of tying machine is knotting. Typical knotting speed of a knotter
is from 60 to 600 knots per minute.
Some automatic tying machines can knot extremely short tails of yarns
(5 mm).
Cone winder:
A machine used for transferring yarn from one package to another.
Beam warping:
Winding a part of the total number of ends of a warp in full width on to a back
beam.
Direct warping:
Winding single end yarn packages of same color on to a common flanged
beam before or after sizing is called direct warping. It is done for producing
single color fabric.
Creel capacity greater than 12,000.
Sectional warping:
For producing fancy yarn, winding differently colored yarns section wise on a
tapered beam before sizing is called sectional warping.

1. Primary Motion
In order to interlace warp and weft thread to produce fabric on any type of
weaving machine 3 primary motion is necessary:
I) Shedding:
Shedding is the first primary mechanism of weaving. It is the process of
separating the warp thread into two layers to form a tunnel called shed
(through which shuttle carrying weft passes) is known as shedding.
During shedding some yarns are raised up and some are depressed
down create a tunnel.
II) Picking:
Picking is the second primary mechanism of weaving. The method of
passing the weft threads which traverse across the fabric through shed is
called picking. The inserted weft is called a pick.
III) Beating:
It is the process of pushing the pick into the already woven fabric at a
point known as fell of the cloth .By pressure of wraith to jointed feed
side of the cloth is called beating.
2. Secondary Motion
I) Take up motion:
The motion which with draw (wound up) fabric from the weaving area at
a constant rate and thus give required pick spacings and winds the fabric
on to a roller is called cloth control or Take up motion. Positive Take up
motions is mechanically driven. Negative Take up motions is spring
drive.
II) Let off motion:
The motion which deliver warp to the weaving at the required rate and
at a suitable constant tension by unwinding it from a flanged known as
weavers beam is called let off motion.
3. Tertiary Motion
Tertiary motion is not must for fabric production but it is used for higher
production.
1. Warp Stop Motion: Machine will be stopped electrically or mechanically.

2. Weft stop motion: It may be two types-
(a) Side weft motion & (b) Centre weft motion.
3. Reed stop motion: Two types-
(a) Fast reed motion.
(b) Loose reed motion.
KNITTED FABRIC
Knitting:
The second most frequently used method of fabric construction.
The propularity of knitting has been growing tremendously because of
versatility of techniques, adaptability of the many new MMF and growth in
consumer demand for wrinkle resistant, stretchable, sung fitting fabrics
particularly in the greatly expanding areas of sportswear and other casual
wearing apparel. Today, the usage of knitting fabrics ranges from hosiery,
underwear, sweater, slacks, suits and coats, rugs and home furnishing.
Knitting is the method of creating fabric by transforming continuous strands
of yarn into a series of interlocking loops, each row of such loop hanging by
the one immediately preceding it. The basic element of knit fabric structure is
the loop intermeshed with the loops adjacent to it on both side and above and
below it.
Types of knitting:
There are two types of knitting-
1. Warp knitting and
2. Weft knitting.
Warp knitting:
Warp knitting is a method of forming fabric by knitting in which the loops are
made in vertical way along the length of the fabric from each warp yarn and
intermeshing of loops takes place in a flat form on a length wise basis.
Fig: knitting structure.

Weft knitting:
Weft knitting is a method of forming fabric by knitting in which the loops are
made in horizontal way from a single yarn and intermeshing of loops takes
place in a circular or flat form on a course wise basis.
Course:
The loops that runs along the fabric width is called course.
Wales:
The loop which runs across the length of fabric is called wales.
Needle:
The needle is primary element of knitting machine, it is a thin metal plate with
hooked part and it helps to form loops.
Types of needle-
1. Latch needle
2. Bearded needle and
3. Compound needle.
Sinker:
The sinker is the second primary element of knitting machine, it is a thin metal
plate which acts individually or collectively approximately at right angles from
the hook side between adjacent needles.
Function of sinker:
1. Loop formation
2. Holding down
3. Knocking over.

Cam:
Cams are devices which convert the rotary machine drive in reciprocating
action of the needles and other elements.
Gauge:
The needle gauge of a knitting machine is a measure expressed the no of
needle per inch of the needle bed or needle bar.
Suppose for latch knitting machine gauge, N = number of needles per inch.
GSM:
It means the grams per square meter of a fabric. GSM is an important
parameter in terms of fabric weight. GSM can be calculated by following
formula-
GSM = gm/sq-meter
= gm/sq-meter

DIFFERENCE BETWEEN WEAVING AND KNITTING
Topics Weaving Knitting
1.Definition The fabric forming process
by interlacement of warp
threads.
The fabric forming process by
intermeshing of loops.
2.Elasticity Very less or no elasticity. The fabric shows high amount
of stretch and elasticity due to
loop structure.
3.Dimentional
stability
Good dimensional stability
which causes less shrinkage.
Less dimensional stability.
4.Durability More durable. Less durable than woven
Fabrics.
5.Moisture
absorption
The fabric absorbs less
moisture.
The knitted fabrics absorb more
moisture because of their loose
construction.
6.Slacking
and low
sening
The fabric provides good
stability due to intersecting
of yarns at right angle.
It creates problem after wearing
for along time.
7.Air
permeability
Air is less permeable due to
compact construction woven
fabric.
Air permeability is more due to
voluminous structure of knitted
fabric.
8.Crease Woven fabrics are more
inclined to crease .So ironing
and iron retention are better
knitted fabric.
Knitted fabrics are more
resistant to crease. So it
requires no ironing.
9.Production
cost
Production cost is more due
to warp preparation and
desizing process.
Production cost is less due to
modest manufacturing process.
10.Yarn TPI of yarn is comparatively
higher than knitting yarn.
TPI of yarn is comparatively
lower than woven fabric.

Singeing:
Singeing is the process carried out to remove loose hairy fibers from the
surface of the yarn or fabric. It is necessary for level dyeing and to increase
luster of the fabric. It is generally carried out for woven fabric.
Desizing:
Desizing is the process of removal of size materials (starch, gum etc) from the
warp yarn of woven fabric. Desizing is the first treatment of wet process n
textile.
It can be done by acid, alkali or enzyme.
Scouring:
Scouring is the process by which all natural fat, oil, wax as well as dirt and
other impurities are removed for producing a clean textile material.
It is done mainly with soap/detergent and alkali.
Bleaching:
Bleaching is the process for improving the whiteness of textile materials by
removing the natural coloring matters. Bleaching produces a pure and
permanent white effect on fabric which is suitable for level dyeing and sharp
printing.
Hydrogen per oxide (H2O2), Sodium hypochlorite (NaOCl), Sodium chlorite
(NaClO2) and Bleaching power (Ca(OCl)Cl) can be used as bleaching agent.

Mercerizing:
Mercerizing is a physio-chemical process where cotton yarn/fabric is treated
with 15-20% Caustic Soda(NaOH) solution to improve their tensile strength,
lusture, dye affinity etc.
Dyeing:
Dyeing is a distribution process which is happened between textile materials
and dyes in a dyeing machine/dye bath.
There are different dyes like direct dye, acid dye, vat dye, sulpher dye,
reactive dye, disperse dye, azoic dye etc.
Printing:
Textile printing is the process of applying color in ink or paste form on fabric
for producing specific design/motif in one or more colors.
or,
Textile printing is one kind of localized dyeing that is dyes or pigments are
applied locally or discontinuously to produce various design on the fabric with
a motif or motives in one or more colors.
Finishing:
In textile manufacturing finishing refers to any process performed on yarn of
fabric after weaving or knitting to impart look, performances, hand feel etc. of
the finished textile or clothing according to buyer requirement. Finishing can
be done in two forms, in tube form or open width form.
Finishing is of two types-
Finishing
Physical Chemical
Temporary
e.g. Calendaring,
Embossing,
Beetting,
Compacting etc.
Permanent
e.g. Raising,
Sanforizing.
Temporary
e.g. Starching,
Weighning,
Softening.
Permanent
e.g. Mercerizing,
Water repellent,
Flame retardant,
Resin finishing.

Physical finishing:
The finishing process usually involve in specific physical treatment to cause
change in appearance is called physical finishing.
Example: Calendaring, embossing, raising, sanforizing etc.
Chemical finishing:
The finishing process which is performed by application of chemical which may
react with the fibre is called chemical finishing.
Example: Starching, weighting, mercerizing, resin finishing etc.
Temporary finishing:
The finishing process where deposited material or applied treatment may be
removed by easy washing or any subsequent process is called temporary
finishing.
Example: Calendaring, compacting, starching etc.
Permanent finishing:
The finishing process where deposited material or applied treatment stables
upto last stage of the process and not removed by easy washing or further
process is called permanent finishing.
Example: Raising, brusting, mercerizing etc.
Stentering:
An open-width fabric-finishing machine in which the selvedges are so held by
attachments to a pair of endless travelling chains that the fabric is finished to
a specified width.
The treatments of fabrics as its full width in the unfold state in contrast to rope
form.
Calendaring:
After scouring, bleaching, dyeing fabric need to dry finally to retain its delivery
shape and dimension. But at this stage fabric may become least lusterous, as
the threads in the fabric become wavy or crimp type. So we need to parallel
the fabric surface to make them oriented. To fulfill this requirements fabric is
passed through some rollers at high temperature and tension, this is known as
calendaring. It’s a temporary finish.

The act of taking out color from the dry and wet cloth by rubbing or scouring.
Grain line:
Normally pattern pieces carry a line is called grain line. When pattern pieces
are laid down during marker making over the cloth, the grain line should be
parallel to the warp if the fabric is woven and wales in case of knitted fabric.
Drape:
It is a character of fabric which indicates of flexibility and suppleness of fabric.
The degree to which a fabric falls into graceful folds when hung or arranged in
different positions.
FOB (Free on Board):
It is the value of the product which is claimed or fixed without transportation
cost of the goods.
C & F (Cost and Freight):
It is the value of the product which is claimed or fixed including transportation
cost of the goods.
CIF (Cost, Insurance and Freight):
It is the value of the product which is claimed or fixed including transportation
cost and insurance cost.
C.M order (Cost of Making):
Buyer will provide all the fabric and accessories. Manufacturer has to make
only garment and he will get the making charge only.
C.M.T (Cost of Making with Trimming) order:
Buyer will provide all fabric. Manufacturer will get the making charge and at
the same time will get the trimming cost.
Ligne no:
It is the measuring unit of the button. It indicates the diameter of button.
If diameter increases, ligne no also increases.
Where, 1 Ligne = 0.025inch or 0.635 mm

L/C (Letter of Credit):
A guarantee letter of payment. This letter ensures that seller will get his
payment after delivery of the goods.
Or,
It is a commitment by an opening bank account on behalf of the importer in
favor of the exporter that the bills drawn by them on the importer countries
covering the shipment of specified items and quality of goods within stated
period will be paid in exchange of documents under certain items and
conditions.
Quota:
It is an agreement between governments of the importer country and the
exporter country. In details it is the quantities of garments of different
categories upon the manufacturing countries according to business policy.

11.It takes few hours to an apparel. 11.It takes less time to make an
apparel.

Humidity:
Humidity is term used to describe the amount of moisture present in the
atmosphere. This can be described in terms of either Absolute Humidity or
Relative Humidity. Most of the fibers are hygroscopic in nature that is they are
able to absorb water vapour from moist atmosphere and desorbs or loss water
in a dry atmosphere.
There are two types of Humidity-
1. Absolute Humidity and
2. Relative Humidity.
Absolute humidity:
It is the weight of water present in a unit volume of moist air. It is the actual
density of water vapour in the atmosphere and it can be expressed in terms of
grain per cubic foot or grams per cubic meter.
Relative humidity:
It is the ratio of the actual vapour pressure to the saturated vapour pressure
at the same temperature of air is called relative humidity, which is expressed
as a percentage.
i.e. RH = 100
The changes in the relative humidity will change the amount of moisture in a
sample of material which may be expressed in terms of moisture content and
moisture regain.
Moisture content:
It is defined as the weight of the water in a material expressed as a
percentage of the total weight of the material.
i.e. Moisture Content = 100
MC% = 100
Where,
W = Weight of water.
D = Oven dry sample weight.
MC = Moisture content.
Actual vapour pressure
Saturated vapour pressure
Weight of water
Total weight of material
W
W + D

Moisture regain:
It is defined as the weight of the water in a material expressed as a
percentage of the oven dry weight of material.
i.e. Moisture Regain = 100
R% = 100
Where,
W = Weight of water.
D = Oven dry sample weight.
MC = Moisture regain.
Standard atmosphere:
It is defined as an atmosphere at the prevailing barometric pressure with a
relative humidity of 65% and a temperature of 200
C (680
F).
Standard testing atmosphere:
It is an atmosphere with a relative humidity of 65 2% and a temperature of
200
20
C (680
40
F). In tropical and sub-tropical regions like India or
Bangladesh, temperature 200
C is very difficult to obtain, so higher standard
temperature 270
20
C (810
40
F) is used.
Oven dry weight:
The constant weight of textile material obtained by drying at a temperature of
1050
C.
Weight of water
Oven dry weight of material
