摘　　要：无捻纱的退维工艺是织制无捻纱织物的关键工艺,退维过程的控制一直是困扰水溶性维纶伴纺与混纺产品开发的难点。为准确测试无捻纱退维的时间,采用纱线强力测试法和称重法对无捻纱的退维时间进行验证测试,2种测试方法基本相符,30 min左右合股纱线上的维纶能够全部溶解,为实际生产中无捻纱织物退维时间的确定提供了可靠的依据。The dissolving of the water-soluble polyvinyl alcohol （PVA） fiber in the ply yarn is the key process of fabric manufacturing with untwisted yams. Control of dissolving time has been a long-standing problem in the product development associated with PVA blends. To control the optimal time, two methods were designed, i.e., yarn strength testing method and weight method. The results of the two methods showed eoineidently that the PVA of the ply yarn could be dissolved probably in 30 minutes. And this conclusion provides a reliable parameter for industrialized production.
