纬编间隔织物的编织工艺与压缩性能探讨

采用涤纶单丝作为间隔纱和低弹涤纶长丝作为表层纱,在双面圆纬机上编织了几种不同规格的纬编间隔织物,并探索了编织工艺.对这些织物的压缩性能进行了测试,分析了压力-变形曲线和影响压缩变形和回复性能的因素.实验结果表明,在其它条件都相同时,间隔纱细度、织物密度、筒口距离的增加,有利于减小织物的压缩变形和提高回复性能.

The Investigation on Knitting Technology and Compressive Properties of Weft-knitted Spacer Fabric

Using polyester monofilament as spacer yarn and low-stretch polyester filament as face yarn, several kinds of weft-knitted fabric with different specifications were produced on a double circular knitting machine and related knitting technology was explored. Also, the compressive properties of the fabrics were measured, and the pressure-deformation curve and some factors influencing the compressive deformation and recoverability were analyzed. The experimental results indicate that under equal other conditions, the increase of spacer yarn fineness, fabric density and the distance between dial and cylinder is favorable to reducing compressive deformation and improving recoverability.
