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 represent a promising and sustainable future for the textile industry. Their biodegradability, comfort, and versatility make them an attractive choice for eco-conscious consumers and businesses. As research and technology continue to advance, manmade protein fibers are likely to play a more significant role in creating textiles that are both environmentally friendly and high-performing. These fibers are a testament to the industry’s commitment to innovation and sustainability in the pursuit of a greener future. 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.
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
Sewing Threads are manufactured by twisting short fibres or by continuous filaments yarns. At times two or more yarns are combined to make the thread to get the required strength.
Manmade fibers are used everywhere for apparel, fabrics, home furnishing, industrial equipments, medical equipments, fire blocking, filtering, auto industry etc.
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.
Man-made fibers are fibers in which either the basic chemical units have been formed by chemical synthesis followed by fiber formation or the polymers from natural sources have been dissolved and regenerated after passage through a spinneret to form fibers. This fibre came to success when the researchers obtained a product by condensation of molecules presenting two reactive aminic groups with molecules characterised by two carboxylic reactive groups.
The protein fibers are formed by natural animal sources through condensation of a-amino acids to form repeating polyamide units with a various substituent on the a-carbon atom. In general, protein fibers are fibers of moderate strength, resiliency, and elasticity. They have excellent moisture absorbency and transport characteristics. They do not build up a static charge. Example of some these fibers is Wool, Silk, Mohair, Cashmere etc.
Fiber is a hair-like strand of material. It is flexible and can be spun or twisted for weaving, braiding, knitting, crocheting, etc. to make desired products. Fibers can be obtained in natural form from plants and animals as well as in synthetic form. Man-made or synthetic fibers are either made up of chemicals or by processing natural fibers to create new fiber structures/properties.
