Manmade Fiber

Mineral and Metallic Fibers

A number of fibers exist that are derived from natural mineral sources or are manufactured from inorganic and mineral salts. These fibers are predominantly derivatives of silica (Si02) or other metal oxides.

Vinyl Fibers

Vinyl fibers are those man-made fibers spun from polymers or copolymers of substituted vinyl monomers and include vinylon, vinyl, vinylon-vinyl matrix (Polychlal), saran, and polytetrafluoroethylene fibers.

Polyolefin Fibres

Polyolefin fibers are those fibers produced from polymers formed by chain-growth polymerization of olefins (alkenes) and which contain greater than 85% polymerized ethylene, propylene, or other olefin units.

Polyester Fibers

Polyesters are those fibers containing at least 85% of a polymeric ester of a substituted aromatic carboxylic acid including but not restricted to terephthalic acid and f-hydroxybenzoic acid.

Acrylic Fibers

Acrylic fibres are polymers formed by addition polymerization of at least 85% by weight of a chemical called acrylonitrile or vinyl chanide. To polymerise vinyl cyanide the double bond between the first two carbon atoms is broken and the…

Polymer Fibres

Polymers are made up of many molecules all strung together to form really long chains. Things that are made of polymers look, feel, and act depending on how their atoms and molecules are connected.

Manmade Protein Fibers

Manmade protein fibers are produced by dissolving proteins like casein from milk, soya bean protein, and zein from corn in diluted alkali and forcing these solutions through a spinneret into an acid-formaldehyde coagulating bath.

Synthetic Fibers

The synthetic man-made fibers include the polyamides (nylon), polyesters, acrylics, polyolefin, vinyl, and elastomeric fibers, while the regenerated fibers include rayon, the cellulose acetates, the regenerated proteins, glass and rubber…
