Shrink-Proof Treatment Parameter Optimisation of Cashmere Yarn

Li Long, Wang Wei, Zhang Xian, Wu Lei, Yang Dan

Fibres & Textiles in Eastern Europe

Vol. 30, no. 3

Cashmere fiber has soft hand and good elasticity. However, it exhibits shrink because of its scale. In this work, cashmere yarn (38.26 tex) was treated using NaCl-KMnO4 to reduce the shrink of cashmere yarn. Orthogonal design and fuzzy comprehensive evaluation were used for optimizing treating parameters. Experimental results showed that the yarn shrink percentage of treated yarn was 0.56% which was less than that untreated yarn, and the treated yarn strength had a little drop compared with untreated yarn. The fiber scale outline of treated yarn could be observed by SEM, but the scale edge is blunt and irregular.
