It is a regenerated cellulosic fiber obtained from natural sources like wood pulp, cotton linters and related agricultural products.
Effect of bleaching: It is damaged by strong oxidizing agents.
Effect of Organic solvents: it has the resistance towards organic solvents.
Action of soaps: use of poorly made soap and improper use of soap leads to cause rancidity odor in rayon fiber.
Mildew and insects: it does not have the resistance towards mildew and insects. It causes discolorations, stains, loss in strength and luster.
Dyes: can be dyed with direct, vat and Sulphur dyes.
Difference between viscose and rayon: viscose made from plant fibers through cellulose xanthation process. Rayon made from wood pulp through cellulose immersion process.
Structure: structure of viscose rayon is similar to cotton. But the polymer chains of viscose rayon are shorter than cotton.
Degree of polymerization of rayon: 400-700
Modified viscose rayon:
High wet modulus yarn
Super high wet modulus yarn
viscose rayon is used for making apparel.
Used for making curtains, future covering, table cloths, cushions, bedspreads, quilt covers, blankets, lace, transport furnishing, tire cords and sportswear.
