Viscose fibre was discovered in 1891 by English scientists, Cross and Bevan. It was heralded as the new fibre to replace silk and is sometimes called artificial silk. This fibre has been produced widely all over the world, usually in countries which have a plentiful supply of trees, as it is this which provides the raw material for the fibre. The raw material is actually wood pulp, but also short cotton fibre, unusable for spinning, is also a raw material. The first commercial production in America was opened in 1910 by the American Viscose Company and the fibre became known as viscose rayon, with other producers following suit. The first use for the fibre was in car tyres as reinforcing. Massive volumes for the fibre were never achieved due to the invention of other cheaper fibres, such as Polyester and Nylon. Wood is pulped into sheets of cellulose and steeped in an alkali solution. After this process the sheets are shredded into cellulose crumbs and treated with carbon disulphide, which changes the chemical structure of the cellulose. This is then dissolved in a solution of sodium hydroxide, to make a thick solution (hence the name viscose). This solution is then machine forced through spinnerets, to produce viscose fibre in a wet spun process. The resulting fibre is then dried, crimped and cut to the required length.

Rayon fiber is used in a wide range of applications including textiles and nonwoven products.

In the textile sector, Sateri's viscose staple fiber is used to improve comfort and appearance. They are:

Soft and silky to the touch
Moisture-absorbing
Non-allergenic
Anti-static
Easy to dye and excellent at retaining color brilliance

Viscose Rayon is a manufactured regenerated cellulose fibre. As it is produced from naturally occurring polymers, it is neither a truly synthetic fibre nor a natural fibre; it is a semi-synthetic or artificial fibre. It usually has a high lustre quality giving it a bright sheen. Short cut viscose fibre is commonly used in applications requiring moisture absorbency like nappies

Precision Cut Viscose Rayon Semi-synthetic fibres

Precision or short cut fibres in a range of decitex sizes and cut lengths are used for reinforcement in a wide variety of industrial applications. These include the manufacture of adhesives, castings, composites, filters, lead acid battery plates, paints, paper, sealants and refractories. Fibres are available in a range of synthetic and natural materials depending on the end use.

In the nonwoven sector, viscose staple fiber provides high absorbency, high purity and bio-degradability, thus making it ideal for use in baby wipes, feminine hygiene products, medical pads and household wipes.

0.95 decitex

Viscose Rayon is a manufactured regenerated cellulose fibre. As it is produced from naturally occurring polymers, it is neither a truly synthetic fibre nor a natural fibre; it is a semi-synthetic or artificial fibre. It usually has a high lustre quality giving it a bright sheen.

3.30 decitex

Viscose rayon is most commonly used in the production of standard paper and speciality papers. As the material is 100% biodegradable it is also globally accepted for use in environmentally friendly applications. It has been used in oil well drilling operations to replace non-biodegradable synthetic fibres.
