2. Definitions
Strength: Ability to resist being pulled or torn
apart when subjected to stress or tension.
Elasticity: To the extent to which fiber can be
elongated by stretching and then returning to
its former condition of size or length.
Resilience: to the extent to which a fiber can
be deformed by compression or crushing
and return to its original position.
Drapability: The ability of a fabric to hang
easily and fall into graceful shape and folds
indicates its drapability.
3. Heat Conductivity: The extent to which
heat can be conveyed through a fiber or
a fabric.
Absorbency: The ease and extent to
which moisture can penetrate into a fiber
determines its absorbency.
Moisture Content : The amount of water
present in a fiber as its integral part.
Perspiration: Perspiration can be acidic
or alkaline, depending upon individual’s
metabolism
5. Cotton:
Cotton fiber is classified as a natural
vegetable seed staple fiber.
Properties:
Strength : Good
Length : 0.5-2.5 inches
Tenacity : Dry 3-5 g/d
Wet 3.3-6 g/d
Elastic Recovery: Low
Elongation : 3 – 10%
Density: 1.54 g/cm3
Cleanliness/washability: Not good
6. Cotton
Dapability: Moderate
Static Build-up: No static build-up
Resistance to acids: No resistance
Resistance to alkali: No resistance
Resistance to Sunlight: Prolong exposure weakens it.
Resistance to insects, bacteria, fungus and mildew: They
damage cotton
Cotton catches fire easily.
Affinity for dyes: Good
Heat Conductivity: Good
Absorbency: Good
Resistance to Perspiration: alkali perspiration does not
deteriorate cotton, however acidic slightly effects it
7. Cotton
Uses:
o Because of its high capacity to absorb, hold and dry
moisture, cotton offers maximum comfort under extreme
heat and humidity.
o It is a fiber that “breathes”. Consumer prefers cotton for its
comfort, laundrability, absorbency, ease finishing and
dyeing.
o It is a preferred fabric for children & for anyone who has a
sensitive skin and is allergic to other fibers, since it is non
allergic.
o A wide range of fabric construction methods can be
employed including weaving, knitting as well as non woven
techniques.
o Cotton is used universally for a variety of apparel (both
inner and outer wear).
