Rationale:
The exponential growth of Textile has benefited the mankind. In the field of Textile, Fibre is the basic raw material from which we are manufacturing yarn and fabric. So studying the polymer science, the manufacturing process of various types of regenerated fibres like viscose, high tenacity viscose, polynosic, cellulose acetate and their properties are very important to decide its end uses.
