Natural Textile Fiber:-
Natural textile fibers include those
fibers produced by plants, animals, and geological processes.
Classification Of Natural Fiber:-
They can be classified according to their origin.
1. Vegetable origin …...(Cotton and Jute Fiber)
2. Animal origin …… (Silk and Wool Fiber)
3. Mineral origin……. (Asbestos Fiber) Md. Yousuf Hossain, Green University Of Bangladesh, [email protected]
Properties of Textile Fiber:- To be a textile fiber it should have some properties.
Normally properties of textile fiber are three types
A) Physical Properties.
B) Mechanical Properties.
C) Chemical Properties.
Md. Yousuf Hossain, Green University Of Bangladesh, [email protected]
Cotton:-
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective capsule, around the seeds of cotton plants of the genus Gossypium.
The fiber is almost pure cellulose. Under natural condition, the cotton balls will tend to increase the dispersion of the seeds.
Md. Yousuf Hossain, Green University Of Bangladesh, [email protected]
Chemical Composition of Cotton Fiber:-
Cellulose…………………………………..... 91.00%
Water………………………………………... 7.85%
Protoplasm , Pectins………………………… 0.55%
Fat and Wax ………………………………… 0.40%
Mineral Salts………………………………... 0.20%

JuteFiber:- Jute fiber is a natural bast fiber. It
is one of the most affordable
natural fibers and is second only to
cotton in amount produced and
variety of uses of vegetable fibers.
It is harder than other textile fibers.
It is environment friendly.
Md. Yousuf Hossain, Green University Of Bangladesh, [email protected]
Chemical Composition of Jute Fiber
Cellulose........................................ 65.2%
Hemi-celluloses ............................ 22.2%
Lignin ............................................ 10.8%
Water soluble matter....................... 1.5%
Fat and wax ................................... 0.3 - 1.0%

Silk:-
Silk is a natural protein fiber
which is obtained from the
cocoons of the silkworm. It
is a natural filament
produced by the salivary
glands of silkworms, which
are a type of moth that feeds
on the mulberry bush.
Md. Yousuf Hossain, Green University Of Bangladesh, [email protected]
Chemical Composition of Silk Fiber Fibroin 76%
Sericin 22%
Fat & wax 1.5%
Mineral salt 0.5 %
Md. Yousuf Hossain, Green University Of Bangladesh, [email protected]
Wool fiber:-
Wool fiber is the natural hair
grown on sheep and is
composed of protein
substance called as keratin.
Wool is composed of carbon,
hydrogen, nitrogen and this is
the only animal fiber, which
contains sulfur in addition.
Md. Yousuf Hossain, Green University Of Bangladesh, [email protected]
Chemical Composition of Wool Fiber Keratin 33%
Dust 26%
Suint 28%
Fat 12%
Mineral matter 1%
