Carbon fibres are extremely strong, thin fibre, made of aligned carbon crystals with the shape of a honeycomb and consisting of long, chainlike molecules of pure carbon that are made by charring synthetic fibres such as rayon in the absence of oxygen.
ARAMID is a synthetic fibre that is produced by spinning a solid fibre from solution. The initial preparation of the polymer is generally achieved by a chemical reaction between the amine group and a carboxylic acid halide group.
Fiber is a fine hair-like structure and is considered the raw materials of textiles. The fiber is extracted from various sources for commercial use. In addition to obtaining from animals, plants, and minerals, many of the fibers are artificially generated as well. Here is a list of most commonly used textile fibers.
Manmade fibers are manufactured using different mechanical and chemical processes for example Synthetic fibers from thermoplastics are produced by extruding the molten plastic through extrusion dies (spinnerets) into a stream of cold air that cools and solidifies the plastic. (The operation is referred to as melt spinning.)
The new spinning systems clearly avoid the limitations produced by the twist insertion mechanism. It is possible to increase the twist insertion rate and the yarn production speed quite considerable. Various spinning techniques specifications.
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 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.
Certain natural cellulose fibers are treated and re-produced for specific purposes. The famous fibers such as Viscose Rayon, Acetate etc. are produced by processing various natural polymers.
Fibres have traditionally been used in all cultures of the world to meet basic requirements of clothing, storage, building material, and for items of daily use such as ropes and fishing nets.
Generally, a set number of yarns are used for the formation of fabrics. Also, a number of techniques are used for producing fabrics such as weaving, knitting, and felting. The type of fabrics varies by the fibers, the fabric formation techniques, machinery used for producing them, and finishing techniques. Fabrics can also be made differently based on the application.
