Structure and Property Discussion of Fine Carrier Spinning Yarn Before and After Resolving Water-soluble PVA
摘要
Abstract
Property changes of water-soluble polyvinyl alcohol carrier spinning fine pure cotton yarn before and af ter resolving water-soluble PVA were discussed. The yams properties before and after resolving water-soluble PVA were tested and analyzed. The research shows that after resolving water-soluble PVA,ply structure becomes looser,the ply di ameter becomes thinner,the twist is added and the arrangement of fiber become disorder. Ply strength is reduced about 50% , the breaking elongation rate and initial modulus were reduced more than 8% , the weaveability was worsen. Ply evenness CV was worsen obviously,thin places,thick places and neps were increased greatly. It is considered that fiber blending ratio and even blending should be ensured strictly when producing high density thin fabric by resolving yarn, quality of polyvinyl alcohol carrier spinning should be improved. Twists of yarn and ply should be set rationally. Water-soluble PVA processing should be optimized as key,the loss to yarn strength and elongation should be reduced as much as possibly.关键词
