[35] [36] [better source needed] High-wet-modulus rayon is a modified version of viscose that is stronger when wet. It can be mercerized like cotton. HWM rayons are also known as "polynosic". [contradictory] Polynosic fibers are dimensionally stable and do not shrink or get pulled out of shape when wet like many rayons. They are also wear ...
Natural fibres shrink more than synthetic fibres. Synthetic fibres are more stable due to their crystalline and thermoplastic nature. They do not shrink, whereas natural fibres are more prone to shrink because of more amorphous regions in their fibre structure which allows more absorption of water, swelling of fibres and increased lubricity ...
The aim of the process is a cloth which does not shrink significantly during production, cutting, ironing, sewing, or especially, by wearing and washing the finished clothes. Cloth and articles made from it may be labelled to have a specific shrink-proof value (if pre-shrunk), e.g., of under 1%.
Textile finishing machinery, Red Bridge Mills, Ainsworth, 1983 In textile manufacturing, finishing refers to the processes that convert the woven or knitted cloth into a usable material and more specifically to any process performed after dyeing the yarn or fabric to improve the look, performance, or "hand" (feel) of the finish textile or clothing.
Spandex, Lycra, or elastane is a synthetic fiber known for its exceptional elasticity. It is a polyether - polyurea copolymer that was invented in 1958 by chemist Joseph Shivers at DuPont . [ 1 ] [ 2 ] [ 3 ]
Wrinkle-resistant finishes were developed in the early 20th century as a way to deal with fabrics derived from cotton, rayon, and linen, which were found to wrinkle easily and retain the wrinkles. These treatments have a lasting effect on the fabric. [ 2 ]
Heat setting is a term used in the textile industry to describe a thermal process usually taking place in either a steam atmosphere or a dry heat environment. The effect of the process gives fibers, yarns or fabric dimensional stability and, very often, other desirable attributes like higher volume, wrinkle resistance or temperature resistance.
A modacrylic is a synthetic copolymer.Modacrylics are soft, strong, resilient and dimensionally stable. They can be easily dyed, show good press and shape retention, and are quick to dry.
