Abstract/Description: | Cashmere fiber has to be blended with either nylon or water-soluble Polyvinyl alcohol (PVA) as a carrier fiber for spinning on worsted spinning system. The spun yarn is used for producing high-end fashion fabrics. The nylon or PVA portion is then removed from the fabric by treating with hydrochloric acid or hot water. The PVA based process is considered eco-friendly as compared to nylon-based process. However, the whiteness and handle of such fabric is inferior as compared to cashmere fabric produced from nylon-based process. This study attempts to improve the whiteness and handle of the fabric by using dilute sulfuric acid in place of hot water to remove PVA. The fabric produced from newly developed process shows improvement in whiteness index (28%) and handle (20%) than fabric of hot water-based process. It exhibits similar handle like that of cashmere fabric produced from nylon-based process. The new process uses only mild concentration of acid and can be considered as eco-friendly as hot water-based process. The sulfuric acid facilitates easy dissolution of PVA from the fabric and prevents the redeposition of the same. |
