Answer 2

Answer:

Semi-Synthetic Fibers

Semi-synthetic fibres are made from natural raw materials with a naturally occurring long-chain polymer structure and are only modified and partially degraded by chemical processes. Most semi-synthetic fibres are cellulose regenerated fibres, the earliest of which is rayon, also known as viscose.
