What’s the purpose of the “afterfinish” of cashmere fabric?

When the cashmere fabric is in the piece dyeing, the cashmere fiber was damaged due to the high dyeing temperature, so that the texture of the finished dyed fabric was decreased in hand feeling, strength, gloss, freshness and destroyed its natural quality.
To improve it, the “afterfinish” technical treatment became necessary. So here comes the purpose of it.
Firstly, to make cashmere fabric width neat and uniform; size and shape stable. Mainly methods: constant amplitude (pull), mechanical or chemical shrinkproof treatment, wrinkle resistant and heat setting etc.
Secondly, to promote the cashmere fabric appearance, that is to say, to improve the fabric gloss, whiteness, increases or decrease villus of the surface. Mainly methods: Whitening, calendering, electro-optic, sanding, shearing and fulling etc.
Thirdly, to improve the hand feeling, to make it soft and smooth, plump, stiffness, thin or thick integrated touch feeling mainly by chemical or mechanical method.
Fourthly, to improve the durability of the cashmere fabric and it is mainly by chemical methods to prevent the damage or erosion from sunlight, air or microorganisms on the cashmere fiber, and to prolong the service life of it. Methods: such as mothproof, mildewproof finishing etc.
