Grasim of India is the major producer of rayon in the world which is claiming 24% market share. Viscose yarn is yarn made from a cellulose base. Rayon remains an important fibre, although production has declined in industrial countries because of environmental concerns connected with the release of carbon disulfide into the air and salt by-products into streams. In 1889 Chardonnet exhibited fibres made by squeezing a nitrocellulose solution through spinnerettes, hardening the emerging jets in warm air, and then reconverting them to cellulose by chemical treatment.

Silkworms, sheep, beaver, buffalo deer, and even palm leaves are just some of the natural resources that have been used to meet these needs. The filament may be manipulated and modified during the manufacturing process to control lustre, strength, elongation, filament size, and cross section as demanded. Rayon is a very soft material, which is why it is a preferred fabric choice by those who seek comfortable clothing. In the case of rayon and acetate, however, the cellulose is acquired in…. This viscous solution (viscose) is forced through spinnerettes. It can be washed in mild alkaline solutions but loses strength if subjected to harsh alkalies. We will look at the difference further down when we discuss viscose fabric’s manufacturing. Acrylic is also used in artificial wool by combining it wid nylon…to make it strong.
