Het is altijd een teleurstelling wanneer een kledingstuk krimpt in de was. Kunstzijde is de verouderde benaming voor rayon, tegenwoordig meestal aangeduid met de modernere naam viscose.Het is een kunstmatig vervaardigde vezel op basis van cellulose, een natuurlijke grondstof die bijvoorbeeld wordt gewonnen uit houtpulp van bamboe of eucalyptushout.De techniek werd in 1884 uitgevonden door de Franse scheikundige Graaf Hilaire de Chardonnet uit Besançon. As a result, a deep orange gelatinous sodium cellulose xanthate is formed. Both viscose and rayon are made from wood pulp or cellulose. Advantages and Disadvantages of Acrylonitrile Butadiene Styrene (ABS) Polymers. The first commercial viscose rayon was produced by the UK Company, Courtaulds Fibers in 1905. Viscose rayon is suitable for all normal textile needs but it’s not suitable for such purposes as sea-ropes, fishing lines, fishing nets, insect netting or materials subjects to chemical contact. Unlike most man-made fibers, rayon is not synthetic. Developed in an attempt to produce silk chemically, it was originally called artificial silk or wood silk. Also, regular rayon has a tendency to shrink when washed. some depolymerisation occurs and the degree of polymerization falls from about 5000 to 350 in this process. They are contained in a galvanized vessel with a lid and through oxidation with atmospheric oxygen, degradative changes set in. Paul Schützenberger discovered that cellulose could be reacted with acetic anhydride to form cellulose acetate which on saponification can give rayon. Regular viscose rayon does have some disadvantages. Viscose fibre is produced out of Bamboo by keeping Baboo in water for many days. The elasticity of viscose rayon is not high. Viscose heeft veel eigenschappen van katoen, is alleen iets minder sterk als katoen. Then these treated chips are cooked with steam under pressure for 14 hour. Rayon vs Viscose . It is the worldwide preparation process of rayon. Viscose is made by treating the cellulose with sodium hydroxide and carbon disulfide. Production of cuprammonium rayon for textiles started in 1899 in the Vereinigte Glanzstoff Fabriken AG in Oberbruch. When rayon/viscose experienced a resurgence in the 1980s and new millennium, it was brought back to New Zealand under the name viscose. Ageing: After shredding, the crumbs are aged. This inherent weakness is exacerbated when it becomes wet or overexposed to light.

Rayon made from as a result of this process is called viscose rayon. Commercial production started in 1891, but the fiber produced was flammable and more expensive than acetate or cuprammonium rayon. While Rayon’s raw materials can be either bamboo or wood cellulose, Viscose is derived from wood cellulose and plant fibers, which are made into a viscous liquid that then undergo a series of chemical processes.
