Explanation:
Artificial silk, or rayon, is madefrom cellulose, obtained from cotton or wood pulp. The cellulose is dissolved in a substance called alkaline carbon disulphide to make a thick liquid. This is squirted through tiny holes into a bath of acid. It reforms as fibres, which can be spun into yarn.
⟹The process of making silk starts from an alkaline solution of cellulose.
⟹The wood or cotton pulp is treated with caustic soda until a merceriza-tion somewhat similar to the chemical reaction in mercerizing cotton yarn has taken place.
⟹ But the decomposition is carried much farther in making viscose.
