(iii) Starching / Stiffening
Starchisgenerallyappliedtofabricoffinequalityandlightweightorlooselywoven
fibres. Starching makes the fabric heavier, stiff, and crisp. It also adds shine and
smoothnesstothefabric. Cottons–muslin,poplin,cambricandthinsilksaregenerally
starched.

(i) NaturalDyes–Thesewerethefirstdyesknowntomankind.Theseareobtained
fromnaturalsources–vegetables,animalsorminerals. Theseareeco-friendlyand
do not pollute water or land. The residue of these dyes can be safely used as

and expensive. Major natural dyes obtained from plants are turmeric (haldi),
henna(mehndi),madder(manjishta)andindigo(neel).Whiletyrianpurpleand
