The Effect of Salt-Shrinkage on the Silk Union Fabrics by Continuous Treatment System

Abstract

The continuous treatment system of salt-shrinkage and their use to improve stretch and crease resistance by silk union fabrics. Calciumnitrate (specific gravity 1.43) were produced on silk union fabrics. The fabric stretch to the ASTM D3107-07(2008) test over five repetitions was determined. When applied to silk/cotton and silk/wool union fabrics by a continuous treatment procedure, in the presence of sodium nitrate, all of these fabrics gave excellent stretch and crease resistance properties, although the times required varied. The continuous treatment procedure required to achieve stretch and crease resistance, about 3 to 5 minutes.
