Like cotton, viscose fibers are highly flammable (LOI = 18). Learn how your comment data is processed. The specific gravity of viscose rayon is 1.52, which is high compared with wool and cellulose acetate, both of which have value about 1.32. Rayon is a manufactured regenerated cellulose fiber. Viscose or rayon is a synthetic product used as a textile material that is obtained by treating cellulose with a solution of caustic alkali (alkaline substance) and carbon disulfide (volatile liquid used to manufacture certain cellulose fibres). Basic: Good resistance to weak alkalis but strong alkali is harmful for viscose rayon. 100% viscose looks similar to silk — it is semitransparent and glossy. Viscose rayon is the naturally regenerated cellulosic fiber that can be made from naturally occurring cellulosic based material. The top countries of supplier is China, from which the percentage of rayon fabric properties supply is 100% respectively. Prolonged exposure of viscose fabrics to sunlight may result in reduction in the fabric strength. In terms of properties, it has the benefit of becoming more durable when wet.
