摘要
采用驼绒与水溶性维纶制备了几种包芯纱及针织物试样。通过正交试验对驼绒/水溶性维纶包芯纱及其针织物退维过程进行研究,探讨芯纱含量、包芯纱捻度、织物密度、温度、时间对退维率的影响。试验得出:包芯纱退维比针织物退维更容易,但维纶的溶解导致纱线收缩纠缠,且所形成的中空结构在编织过程中会受到破坏,因此选用针织物退维,试验结果表明:采用芯纱含量为19.1%,捻度为325捻/m的驼绒/水溶性维纶包芯纱,针织物总密度为1 368线圈/25 cm2时,在温度60℃下恒温处理40 min,针织物退维率可达99%。
Camel hair and water-soluble PVA were used to prepare core-spun yarns and knitted fabrics with several parameters. After studying the PVA solution processing of the core-spun yarn and its knitted fabric by orthogonal test, the impact of core yarn percentage, twist, fabric density, temperature and time on the PVA solution rate were investigated. The experiments indicated that it＇s easier to dissolve PVA for core-spun yarn than knitted fabric. But the dissolution of PVA caused the yarn shrink and intertwist, and the formed hollow structure will be destroyed in the knitting process. So the dissolving PVA from knitted fabric was chosen and the results showed that adopting core yarn content of 19.1% and twists of 325 twist/m, stitch density of 1 368 circle/25 cm2, treating under 60 ℃ for 40 minutes, the PVA solution rate of knitted fabric can reach the maximum of 99%.
