Viscose Rayon Fiber Textile Fashion Study
Viscose Rayon is discovered by C.F. Cross and E.J. Bevan in 1891. It was discovered in UK. It is one of the oldest man made www.pawsitivepooch.ca know that, viscose rayon is produced from the wood which contains cellulose for this reason it is called regenerated cellulosic www.pawsitivepooch.ca is produced by a spinning process. Viscose - LEVACO LUCRASPIN® VA 347. Surface-active, can be applied either in pulp production or in the alkalisation process. Accelerates the penetration of the pulp in steeping, facilitates the shredding process and activates the xanthogenation process. CS2 demand is lowered and filterability is improved. Appearance: colorless liquid / Active matter (%): 85. Textile Insight: Manufacturing of Viscose Rayon – Viscose The first step in the manufacturing of Viscose Rayon is preparation of wood pulp. Spruce trees are cut into timber. Their barks are removed and cut into pieces of about 7/8" x 1/2" x 1/4". These pieces are treated with a solution of calcium bisulphite [CS2] for 8-12 hours and cooked with steam under pressure for about 14 hours.
