There are two types of Textile Fibres.
1) Natural Fibres.
2) Man-Made Fibres.

Natural Fibres:

Vegetable Origin
Bast Fibres: A) Jute. B) Flex. C) Hemp. D) Kenaf. E) Sunn. F) Urena. G) Ramie. H) Nettle
Leaf Fibres: – A) Sisal B) Manila etc.
Seed Fibres:- A) Cotton.
Fruit Fibres:- A) Coir.

Natural Fibre: Cotton

Animal Origin
Wool & Hair Fibres.
Silk & Other filaments.

Mineral Origin (Asbestos).

Man-Made Fibres:

Natural Polymer Based

• Cellulose Fibres (Rayon).
• Cellulose Ester Fibres.
• Protein Fibres.
• Miscellaneous Fibres.

Synthetic Polymer Based

 Polyamides.
 Polyesters.
 Polyurethanes.
 Polyolefins.
1) Polyethylene.
2) Polypropylene.

• Misscellaneous Fibres.
• Polyvinyl Derivatives

1. Polyacrylonitrile (PAN).
2. Polyvinyl Chloride (PVC).
3. Polyvinyl Alcohol (PVA).
4. Polyvinylidene Chloride
5. Polyvinylidene dinitrile
6. Polystyrene & PTFE

PVC Fibre

Synthetic: The fibre which is obtained by chemical synthesis is called synthetic fibre.

Regenerated: The fibre which is obtained by conversion of natural fibre process is called regenerated fibre.

Man Made Fibre :
Acrylic is a man made fibre in which the fibre forming substance is a long chain synthesized polymer composed of at least 85 % by weight of acrylonitrile units.

Modacrylic is a man made fibre in which the fibre forming substance is a long chain synthesized polymer composed of at least 35 % but not more than 85 % by weight of acrylonitrile units.

Acrulic fibres must contain up to 15 % of a monomer (co-monomer) other than acrylonitrile & modacrylic must contain at least 15 % but not more than 65 % of a co-monomer other than acrylonitrile.

The other co-monomer may be one or a combination. Such as acrylamide, vinyl chloride, vinylidence chloride etc.
