Introduction
Practical knowledge is very much essential for the education of textile engineering and technology. It
makes us capable and perfect to apply theoretical knowledge to the practical life.
That is why the B.Sc. in textile engineering course is extruded over four years followed by two months
long industrial attachment in textile mills. This training provides sufficient practical knowledge on
production, maintenance, mill management, working atmosphere, worker management, quality and
production planning, utility services and machine operations.
Industrial attachment is an important part of study in technical education. This training system is
attached to our study curriculum to achieve adequate practical knowledge and develop the adaptation
power with the industrial environment.
We preferred our attachment in ‘Sinha Rotor Spinning Ltd.’ a concer4n of ‘Sinha Textile Group’ which
is one of the best and modern cotton spinning mills in Bangladesh.
We have taken training for two months from 04-10-2009 to 05-11-2009. During this period, we
acquired knowledge on production, quality control, operation and maintenance of various machines,
A/C plants, chiller, boiler and compressor etc. we also gather some knowledge on purchase of raw
materials and marketing of finished products. We tried the best to learn more about this mill which
will be very helpful in future.

Comments on blowroom:
The blowroom section of Sinha rotor spinning ltd is well equipped with modern machinery. Production
is also higher. But it should be noted here that this spinning deals with 100% cotton only. As a result
it contains only blowroom line that does not present any variation and complexity in machine
sequence and operational procedures as it would be seen in a mill producing blended yarn. For
different counts of yarn, weight should be varied. But in SRSL, it is not carried put and wastage
extraction percentage is not measured regularly. In blowroom section, maintaining a standard RH% is
a must. As auto mixing is available, a proper mixing and opening of material is obtained. The overall
performance of the blowroom line is good.
Carding section
Carding is the process in which fibers are opened, parallelized and removal of dust, impurities, neps,
short fibers are done to produce a continuous strand of fibers called sliver of uniform weight per unit
length.

32
Carding is the heart of entire spinning process and as such requires utmost care. “To card well is to
spin well” is a very widely used saying by all of those who are concerned with spinning technology.
“Well carded is half spun” – demonstrates the immense significance of carding for the final result of
spinning operation.
The carding machines available at Sinha rotor spinning ltd are well equipped with high performance
machinery suitable for constant production at a high rate. In order to produce both carded and
combed yarn simultaneously, the card line is divided into two lines.
Objectives:
a) Individualization of fibers from tuft
b) Elimination of impurities
c) Disentanglement of neps
d) Elimination of dust
e) Producing uniform sliver

Drawing section
The draw frame is an essential section in any spinning mill. The process by which a number of carded
sliver are combined to produce a regular and uniform drawn sliver by drafting and doubling is known
as drawing.
Objectives:
 Strengthening and parallelization of fibers
 To facilitate blending of the fibers
 To remove hook fibers
 To reduce irregularities of fibers by doubling
Types of draw frame: There are mainly two types of draw frames used in Sinha textile mills. They are
mentioned below:
a) Breaker draw frame b) Finisher draw frame

Lap former
It should be realized that the super lap former is used primarily in production of combed yarn. Lap
former is mainly used for processing of pre-comb sliver. Doubling and drawing them is essential
to produce uniform lap which is fed in comber machine.
If pre-comb sliver is fed directly to comber machine, noil extraction percentage rate would be
high, a greater quantity of long fibers would be wasted with short fibers and possibility of needle
breakage in comber machine would be higher. For these reasons, lap former is essential for the
processing of combed yarn. As Sinha spinning mills deals with combed yarn, they use lap formers
conveniently.
Purpose of lap former:
 Fibers in the pre-comb sliver are blended and mixed. Thus blending provides a degree of
compensation of raw materials variation.
 It helps in arranging the fibers with better orientation.
 It helps in better parallelization of the fibers
 The tailing hooks in pre-comb sliver is reversed to leading ones here, which ensures less
fiber damages during combing.

 Number of lap former : 2
 Machine 01 : is used for comb woven or Sudan

Comber
The process of removing short fibers by comber so as to increase the spin ability of the yarn and
remove trash, impurities to produce a higher quality of yarn is called combing.
Objectives of combing:
 Elimination of precisely pre-determined quantity of short fibers
 Elimination of remaining impurities
 Elimination of large proportion of the neps in the fiber material
 Formation of sliver having maximum possible evenness.

WINDING SECTION
Winding is considered as an integral part of the spinning process. Winding not only improve the
quality of the yarn but also step up production at the later process, i.e. weaving, knitting & Yarn
dyeing.
Winding machine commonly used for all types pf fibers (100% cotton, MMF, blended yarn).
Function of winding machine: The following functions are performed in winding machine:-
 To make a suitable yarn package from ring bobbin.
 Yarn clearing and splicing
 Waxing

EYC: EYC stands for Electronic Yarn Clearer. It is used in winding machine in order to avoid
disturbance and consequently cost can result during subsequent processing in the finished product.
All electronic yarn clearer observes the length of a yarn based on the duration of an electric signal.
This time is multiplied with speed of the winder which is given from the winder. Then the diameter is
obtained with yarn sensors operating on two different principles i.e. capacitive and optical principle.
Different EYC & their model are given below:

&
PROCESS CONTROL

63
Production Planning & Process Control
Concept of bale management:
Bale management is a process of inventory control and selection of bales of fibers according to their
properties and also to mix the fibers homogenously to get consistent production as well as quality of
yarn. For bale management, all bale samples are tested and bale with almost similar category are
arranged for homogeneous mixing.
In Sinha Rotor Spinning Mills bale management is bone by bale information advance system (BIAS).
 Bale category i.e. Mic, color grade, staple length
 Bale identification I.e. bale no.
Bale management procedure:
1. At first 100% bales of a lot are tested. Normally micronaire value and color grade are taken
as parameter to be tested.
SL no. Bale no. Mic. Color grade
1 1 4.0 GM
2 2 4.2 SM
3 3 4.1 GSM
- -
1200 1200 4.0 SM
2. After that closely similar MI. (±.03) and color grades bales are selected.
Mic Color grade Total
GM SM(S) SM
3.9 75 25 4 100
4.0 90 8 2 104
4.9 110 20 3 135

64
3. Then the mi. which have the major proportion in the lot are taken
4. Finally a number of bales are selected according to the capacity of the industry
Let,
Total no. of bale: 800
Dailey consumption: 40 bales
No. of days to process the lot: 800/40 = 20

The A/C plant in SSL is for
 Rotor
The manufacturer of A/C plant for SRSL & SSL is BEST AIR.
The main task of A/C plant is to maintain specific humidity in the factory in the shed, for this
it circulates the cooling air. A/C plant without chilling helps to maintain only the RH% without much
difficulty. They can be classified generally as either unitary or central station. Central system is the
most widely used in the textile industry.
The systems principal components are:
1. Air moving devices-fans.
2. Mixing devices for air and washer i.e. Air washers.
Air moving devices are always two types:
1. Return Air fans
2. Supply Air fans
The return air fans return the air to the plant room from where it may circulate or exhausted in the
mill.
The supply of air to the mill from plant room.
Air washer is a device for intimately mixing water and air. The mixing water and air supply by nozzle.
Number of fans in different AC:

Fiber compactor 2 - 2 1 1
Duct Evacuations fan 1 1 2 4 2
Rotary air fan 1 1 2 4 2

97
The following components are a must in an A/C plants:
 Return Air and Supply Air fans.
 Air washer
 Return Air floor grills.
 Exhaust damper
 Fresh air damper
 Supply air ducts and grills
 Face and bypass dampers on the air washer
 Control panel for Automatic control the RH and Temperature.
The fresh air come from outside, air is sucked by fan. Then the air humidified in the washer
room. In the washer room air and water is mixing then it supply by nozzle through the supply air
fan. Supply air fan supply the cooling air through the air floor grills. The invisible waste is
separated by filter and fresh air sucked by return air. Then the air is circulating again in the
washer room. It is continuous process.
The humidity and temperature controlling depend on the machine performance, machine life
and on personnel.
A/C plant is must needed for textile industries mainly spinning shed- if A/C plant will run
smoothly then the operators will feel comfortable and performance will be optimum.
Otherwise all these will suffer.

Importance of RH% and Temperature:
The atmospheric conditions with respect to temperature and humidity play very important part
in the manufacturing process of textile yarns. The properties like dimensions, weight, tensile
strength, elastic recovery, electrical resistance, rigidity etc of all textile fiber whether natural or
synthetic are influenced by moisture regain.
Moisture regain is the ratio of the moisture oven-dry weight of the material expressed as
percentage. Many properties of textile materials very considerably with moisture regain, which
in turn is affected by the ambient Relative Humidity (RH) and Temperature. If a dry textile
material is placed in a room with a particular set of ambient conditions, it absorbs moisture and
in course of lime, attains equilibrium.
Some physical properties of textile materials which are affected by RH is given below:
 Strength of COTTON goes up when R.H.% goes up
 Strength of VISCOSE goes down when R.H.% goes up
 Elongation% goes up with increased R.H.% for most textile fibers
 The tendency for generation of static electricity due to friction decreases us RH goes up
 At higher levels of RH, there is also a tendency of the fibers to slick together
Temperature alone does not have a great effect on the fibers- However the temperature dictates
the amount of moisture the air will hold in suspension and therefore, temperature and humidity
must be considered together.
ISO Standard # 139 defines Standard Atmospheric Conditions:
 Temperature of 68
 Relative humidity 75%

Fire Fighting System:
Cotton fiber catches and spreads fire very rapidly. So any kind of accidents related to fire generation
can turn into a devastating calamity in cotton spinning mill. That is why the factory has a well-equipped
firefighting system. Water lines are spread throughout the factory. External and internal firefighting
groups are always ready to action. Some workers practice to go out quickly from the factory during
fire alarm is start. It helps to make any action against fire and reduce any kind of injury.

104
Raw materials:
 Import processing by head office
 Physical received by stock spare LC or invoice as bale or Kg.
 The raw materials are provided for lay down according to lay down plane given from Q.C
Department.
The inventory systems are divided into four groups:
1. Raw cotton inventory
2. Finisher yarn inventory
3. Wastage yarn inventory
4. Spare parts & materials inventory
The inventory is maintained in first in first out system. When store keeper receive some goods, they
write a note in the receive book. They also inform inventory related department. Then the department
made MRR (Material Receiving Report). They made BIN card which contain its name, amount and
other necessary information. Then the materials are stored in the store.
If any department requires any item, they prepare a SR (Requisition Slip) for the particular item and
send it to store. The store then checks its availability and delivers as required.
1. Raw cotton inventory:
In case of raw cotton inventory, QAD department sampling every bale and numbering the bale
according to micronaire value.
2. Finished yarn inventory:
Different lots of finished yarn are given to the production department by Transfer Memo. The store
produces its daily, monthly production report based on the yarns are delivered to order of the
marketing department, the yarns are delivered to the buyers.
3. Wastage yarn inventory:
Different wastage produces from different department. Such as hard waste, pneumafil, FS, dropping
etc. They are measured even day and transferred to store same procedure.
4. Spare parts and materials inventory:
Different type machine parts are stored in the store. When any kind of machine parts broken, damage
etc then this machine parts collect from store.
