Properties of Viscose Rayon

It is a regenerated cellulosic fiber obtained from natural sources like wood pulp, cotton linters and related agricultural products.

Physical properties:

Chemical properties:

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:

Tyre yarn

High wet modulus yarn

Polynosic yarn

Super high wet modulus yarn
