Cellulosefibres(cotton) are known for their comfort during wear and
various other favourable properties.
Resins are used for various wet finishes basically on cellulose and
cellulosic blends.
Resin based finishes create cross linking that increases intermolecular
rigidity.
The resin finishes had been mainly developed for the basic problems of
crease formations on cellulosic fibers ,thus these finishes came to be
known asAnticrease or Crease Recovery finish ,easy care finish or
Resin finish since resins are used for these finish
