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.
