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

The compactor m/c is tubular fabric shrinkage control m/c which can compact the fabric in

length wish direction, to provide overfeed to the fabric while processing in presence of steam &

able to control the shrinkage.

Stenter can be defined as a finishing process in which the open width form

of the fabric is treated in set up the required width, weight & texture as per

customer specifications. These requirements are achieved by a singleprocess
