VISCOSE RAYON:
There are many types of Rayon namely, Nitrocellulose, Acetate, Cuprammonium, Viscose etc., Here we consider Viscose rayon only. Viscose Rayon is a regenerated cellulosic fibre. It is made from cellulose extracted from wood pulp produced from trees. The wood pulp obtained from trees is bleached and then sent to Rayon factories in the form of sheets and boards which contains about 87 to 98% cellulose.
The Viscose fibres are produced both in filament form & staple form. The fibres are produced in cut lengths of 28, 32, 38, 44, 51 & 60 mm for cotton spinning system. The deniers are generally 1.2, 1.5, 2.0, 3.0 & 4.0 .
Rayon is a very versatile fibre and has the same comfort properties as natural fibres. It can imitate the feel and texture of silk, wool, cotton and linen. Rayon is easily bio-degradable. Rayon is used in making apparel (e.g. blouses, dresses, jackets, lingerie, linings, scarves, suits, ties, hats, socks), furnishings (e.g. bedspreads, blankets, window treatments, upholstery, slipcovers), industrial uses (e.g. medical surgery products, non-woven products, tire cord), and other uses (e.g. yarn, feminine hygiene products, diapers)
High Wet Modulus rayon (HWM) is a modified version of viscose that has a greater strength when wet and can be mercerized like cotton. HWM rayons are also known as “POLYNOSIC“.and has a trade name MODAL. High Tenacity rayon is another modified version of viscose that has almost twice the strength of HWM. This type of rayon is typically used for industrial purposes such as tyre cords.
