Rayon Background For centuries humankind has relied upon various plants and animals to provide the raw materials for fabrics and clothing.
It has been suggested that viscose be merged into this article. Discuss Proposed since July They named their material " viscose ", because its production involved the intermediacy of a highly viscous solution. The process built on the reaction of cellulose with a strong base, followed by treatment of that solution with carbon Rayon manufacture to give a xanthate derivative.
The xanthate is then converted back to a cellulose fiber in a subsequent step. The first commercial viscose rayon was produced by the U.
Courtaulds formed an American division, American Viscoselater known as Avtex Fibers to produce their formulation in the United States in In Europe, though, the fabric itself became known as "viscose", which has been ruled an acceptable alternative term for rayon by the U.
The use of woody sources of cellulose makes viscose cheaper, so it was used on a larger scale than the other methods. On the other hand, the viscose process affords large amounts of contaminated waste water.
Rayon was produced only as a filament fiber until the s, when methods were developed to utilize "broken waste rayon" as staple fiber. The physical properties of rayon remain unchanged until the development of high-tenacity rayon in the s.
Further research and development led to high-wet-modulus rayon HWM rayon in the s. Industrial applications of rayon emerged around Substituting cotton fiber in tires and belts, industrial types of rayon developed a totally different set of properties, amongst which tensile strength elasticity was paramount.
Lyocell The Lyocell process relies on dissolution of cellulose products in a solvent, N-methylmorpholine N-oxide. The process starts with woody sources of cellulose and involves dry jet-wet spinning.
It was developed at the now defunct American Enka and Courtaulds Fibres. As ofLenzing's Tencel brand is perhaps the most widely known lyocell fiber producer. Modal is used alone or with other fibers often cotton or spandex in clothing and household items such as pajamas, underwear, bathrobes, towels, and bedsheets.
Modal is processed under different conditions to produce a fiber that is stronger and more stable when it is wet than standard rayon, yet has a soft feel, similar to cotton. It can be tumble dried without damage due to its increased molecular alignment.
The material is softer than cotton and has desirable properties that include higher resistance to shrinking and moisture wicking. Major fiber properties[ edit ] Rayon is a versatile fiber and is widely claimed to have the same comfort properties as natural fibers, although the drape and slipperiness of rayon textiles are often more like nylon.
It can imitate the feel and texture of silkwoolcotton and linen. The fibers are easily dyed in a wide range of colors. Rayon fabrics are soft, smooth, cool, comfortable, and highly absorbent, but they do not insulate body heat, making them ideal for use in hot and humid climates, although also making their "hand" feel cool and sometimes almost slimy to the touch.
However, HWM rayon high-wet-modulus rayon is much stronger and exhibits higher durability and appearance retention. Recommended care for regular viscose rayon is dry-cleaning only. HWM rayon can be machine-washed.
Gallery of textures[ edit ] A sample of rayon from a skirt, photographed with a macro lens.
Another skirt with a different texture. A blouse with a texture similar to the second. Physical structure[ edit ] Regular rayon has lengthwise lines called striations and its cross-section is an indented circular shape.
The cross-sections of HWM and cupra rayon are rounder. Filament rayon yarns vary from 80 to filaments per yarn and vary in size from 40 to denier. Staple fibers range from 1. Rayon fibers are naturally very bright, but the addition of delustering pigments cuts down on this natural brightness.Viscose Rayon We are a successfully ranked entity amongst the famous manufacturers and exporters of outstanding quality Viscose Rayon.
