Rayon, also called viscose [1] and commercialised in some countries as sabra silk or cactus silk, [2] is a semi-synthetic fiber [3] made from natural sources of regenerated cellulose, such as wood and related agricultural products. [4]
Textile fibres or textile fibers (see spelling differences) can be created from many natural sources (animal hair or fur, cocoons as with silk worm cocoons), as well as semisynthetic methods that use naturally occurring polymers, and synthetic methods that use polymer-based materials, and even minerals such as metals to make foils and wires.
Rayon is a manufactured fiber derived from plant pulp. [97] Different types of rayon can imitate feel and texture of silk, cotton, wool, or linen. Fibers from the stalks of plants, such as hemp, flax, and nettles, are also known as 'bast' fibers. Hemp fiber is yellowish-brown fiber made from the hemp plant.
The polymer is formed by free-radical polymerization in aqueous suspension. The fiber is produced by dissolving the polymer in a solvent such as N,N-dimethylformamide (DMF) or aqueous sodium thiocyanate, metering it through a multi-hole spinneret and coagulating the resultant filaments in an aqueous solution of the same solvent (wet spinning) or evaporating the solvent in a stream of heated ...
Rayon and acetate are both artificial fibers, but not truly synthetic, being made from wood. [ 4 ] Nylon , the first synthetic fiber in the "fully synthetic" sense of that term, [ citation needed ] was developed by Wallace Carothers , an American researcher at the chemical firm DuPont in the 1930s.
The material is commonly referred to in the industry as viscose rayon. [4] In 1931, Henry Ford hired chemists Robert Boyer and Frank Calvert to produce artificial silk made with soybean fibers. They succeeded in making a textile fiber of spun soy protein fibers, hardened or tanned in a formaldehyde bath, which was given the name Azlon. It was ...
Vereinigte Glanzstoff-Fabriken (VGF, United Rayon Factories [a]) was a German manufacturer of artificial fiber founded in 1899 that became one of the leading European producers of rayon. During the first thirty years VGF cooperated closely with the British manufacturer Courtaulds and other companies to share technology and maintain prices by ...
Wrinkle-resistant or permanent press or durable press is a finishing method for textiles that avoids creases and wrinkles and provides a better appearance for the articles. . Most cellulosic fabrics and blends of cellulosic-rich fabrics tend to crease or wri
