The synthetic fibre A is chemically a polyamide whereas the synthetic fibre B contains a large number of ester groups. Another synthetic fibre C is made of a polymer D which consists of a number of glucose units joined one after the other.

(a) Which fibre could be (i) terylene (ii) rayon , and (iii) nylon ?

(b) Name the polymer D.

(c) Which fibre (A, B or C) is prepared from a natural raw material ?

(d) Which fibre (A, B or C) contains the same type of grups as those in a PET jar ?

Solution

Fibre A- Nylon
Fibre B- Terylene
Fibre C- Rayon
Polymer D- Cellulose
Nylon are synthetic polymers specially of aliphatic or semi-aromatic polyamides. Terylene is a synthetic polyester fibre or fibre of terephthalic acid. Rayon is made up of cellulose especially from wood pulp. Cellulose is long chain of linked sugar molecules.
