1 Viscose
Viscose was discovered by two English chemists, Charles F. Cross and E. J. Be van, working in collaboration at Kew, near London, who found that when cellulose was treated with disulphide of carbon in the presence of caustic soda, it was converted into a golden yellow plastic compound which dissolved readily in water. A solution of the plastic was of such viscosity that it was named " viscose," a name that was destined to become world famous, seeing that round about 88 per cent of the world production of rayon is now made by the viscose process. In 1892 Cross and Bevan were granted a patent on the viscose process and it was applied to many purposes before the production of a textile thread was successfully accomplished. Fundamentally, the manufacture of viscose rayon is fairly simple. The raw material may be wood pulp, pulp from cotton linters, or a mixture of the two. The greater part of the world's viscose is made from wood pulp. Viscose rayon manufacture comprises seven distinct treatments as follows: - 1. Making and purifying the cotton or wood pulp which forms the cellulose base. 2. Caustic soda treatment of the cellulose base thereby forming alkali cellulose. 3. Treatment of alkali cellulose with carbon disulphide, forming cellulose xanthate. 4. Dissolving the cellulose xanthate in weak caustic soda to form cellulose solution or viscose. 5. Spinning viscose into yarn. 6. Bleaching, purification and finishing of the yarn. 7. Preparing the yarn for weaving and knitting. -

5 Viscose Staple Fibre
This is produced in exactly the same way as continuous filament viscose up to the point of spinning. Instead of making a separate thread at each spinneret, the filaments from all spinnerets on a frame are drawn together into a rope which runs into a cutter which chops the filaments into a definite staple length varying from 17/16 -in. for mixing with cotton or spinning on cotton machinery, up to 2-in. to 8-in. for mixing with wool or for spinning on wool machinery. Viscose staple fibre is also produced in various filament deniers such as 1.5 denier equivalent to cotton fibre thickness, or 3 and 4.5 filament denier equivalent to wool qualities.Dictionary of the English textile terms > Viscose Staple Fibre

7 Viscose Staple Fibre In Colours
During the year 1938 supplies became available of viscose staple fibre in colours. For the wool trade there are three colours in 4.5 filament denier and staple length of 2-in. for woollen spinning, and 4-in. to 6-in. for worsted spinning. For cotton spinning five colours are available in 1.5 filament denier and 17/16-in. staple. These colours have the highest degree of fastness and have only a small surcharge for the colour. The producers state that this coloured staple fibre processes with equal facility with normal undyed staple fibre in the same range of counts, so that the difficulties normally met with in the processing of dyed fibres do not apply to these productions.Dictionary of the English textile terms > Viscose Staple Fibre In Colours

Viscose staple fibre to which has been imparted properties which allow it to be dyed with wool dyes, so that in wool and viscose staple fibre mixture fabrics both materials are dyed simultaneously.Dictionary of the English textile terms > Wool-Dyeing Viscose Staple Fibre
