平绒水洗尺寸变化率的控制

Shrinkage control of velvet fabric

分析了印染平绒生产过程中产生缩水率的原因 ,测试了弹力平绒织物在前刷毛、低温定形、预缩、煮漂、染色和柔软整理等工序中织物缩水率的变化 ;给出了降低缩水率的措施 ,包括降低预缩张力、隔断开柔软预烘与刷烘拉后整理工艺、小量多次防缩处理和转鼓烘燥等。

Reasons for shrink of plain velvet fabrics are analyzed. The shrinkage change in the front brushing, low temperature setting, preshrinking, scouring and bleaching, dyeing and softening are measured, ways to solve them are put forward, such as reducing compressive shrinking tension, separating predryer from brushing-drying-stentering machine during softening, low shrinkage level resistant finish for several times, and the most efficient swing drying.
