2. Some major properties of textile fiber are discussed below :
Uniformity:
To make yarn it is very important for fibers to be similar in length & width.
Flexibility:
The property of bending without breaking is called flexibility.
Cohesiveness:
Cohesiveness is the ability of fiber to stick together in yarn manufacturing
process. It may refer to the surface or skin structure of the fiber, which causes fibers
to stick together. If fiber shape surface do not contribute then coils, crimps or zigzag
shapes are produced for cohesiveness. This property is usually added to the man-
made fibers.
Tenacity:
It is defined as the maximum stress bear by a fiber before it breaks. Tenacity
is expressed as grams of force per denier g/d and grams of force per tex
Cotton 3.0-5.0 g/d

3. Physical Shape:
In addition to high length to width ratio previously discussed, a fiber is
described by average fiber length, cross sectional shape, and surface irregularities.
Luster:
Shine or sheen is called as luster. It is the result of the amount of light
reflected by a fiber, and it determines the fiber natural brightness or dullness.
Density:
Density is the mass per unit volume of a fiber expressed in as grams/cm3 or
pounds/ft3. Density is commonly determined on balance or scale; it is frequently but
incorrectly called as weight.
Moisture Content & Moisture Regain:
Textile fibers in general have a certain amount of water as an integral part of
their structure. Moisture regain or absorbency depends on the fiber morphology or
molecular arrangement and the pore size in the outer layer of the fiber skin. Fibers
with good moisture regain will accept dyes and finishes more readily than fibers with
low regain. Moisture Regain is calculated by the formula:
% Regain = conditioned weight – dry weight/dry weight *100.

4. Elastic Recovery & Elongation:
The amount of stretch or extension that a fiber will accept is called
elongation. Elastic recovery is the percentage of return toward the original length. If a
fiber returns to its original length from a specified amount of extension, it is said to
have 100% elastic recovery.
Resiliency:
Resiliency is the ability of a fiber to return to shape following compression,
bending or similar deformation. Elastic recovery is a significant factor in the resilience
of the fiber, and usually good elastic recovery indicates good resiliency.
High Length to Width Ratio:
Fiber must posses high length to width ratio. This mean that a fiber is at
least 100 times longer than it is wide. Typical ratios of several natural fibers are

5. Shrinkage:
Reduction in the size of textiles after washing, soaking, or treatment
with moist heat; the articles may bereduced in linear dimensions, area, or
volume.
Drapability:
Drape is the term used to describe the way a fabric hangs under its
own weight. It has an important bearing on how good a garment looks in
use. The draping qualities required from a fabric will differ completely
depending on its end use.
Resilience:
The property of a material that enables it to resume its original shape
or position after beingbent, stretched, or compressed; elasticity.

other fibers, including rayon and synthetic fibers such as polyester. It can either be
used in knitted or woven fabrics, as it can be blended with elastine to make a
stretcher thread for knitted fabrics, and apparel such as stretch jeans.
