Silk is made up of Amino acids and it contains 15 amino acids in Polypeptide chains. It has amino groups (NH2) and carboxyl group (COOH).The molecular chains are fully extended and packed closely together. There are some amorphous regions between some crystalline regions, giving silk its elasticity.
PHYSICAL PROPERTIES:-
◘ THERMAL CONDUCTIVITY:- Silk is a poor conductor of electricity and thus susceptible to static cling.

◘ HYGROSCOPIC NATURE:-
It has good absorbency with a moisture regain 11%.Its good absorbency makes it comfortable to wear in warm weathers.

◘ COMFORT:-
Silk is smooth and soft and thus not irritating to the skin.

◘ TENACITY:-
Silk is one of the strongest Natural fibers. Its tenacity ranging from 3.5—5.0 g/d dry and it may lose up to 20% of its strength when wet.

◘ ELASTIC PLASTIC NATURE:-
Its elasticity is moderate to poor if elongated even a small amount, it remains stretched.
