衬垫用经编间隔织物的压陷性能

为获得具有良好支撑性和压力分布的衬垫用经编间隔织物，对不同规格的经编间隔织物的压陷性能进行研究。在双针床拉舍尔经编机上，通过改变织物纵密、间隔丝垫纱角度、间隔丝直径以及脱圈板距离，试织了13种经编间隔织物试样。测试了试样的压缩应力与应变曲线，并以25%和65%压陷硬度和支撑因子作为评价织物压陷性能的指标。探讨间隔丝密度、垫纱角度和直径以及织物厚度对经编间隔织物压陷性能的影响。研究结果指出：织物屈服阶段是研究织物压缩性能的重要阶段；通过各种结构参数的合理配置，可以获取具有理想压缩特性的经编间隔织物衬垫材料。

Indentation force deflection property of cushioning warp-knitted spacer fabric

The aim of this work was to achieve a cushioning warp-knitted spacer fabric with good support and distribution of weight,the indentation force deflection(IFD) property of different warp-knitted spacer fabrics were studied.13 specimens were knitted on double needle bar Rachel machine by changing the lengthwise density of the fabric,lapping angle and diameter of pile yarn and the distance of two comb bars.The compression stress and strain behaviors of samples were tested.The 25% IFD,65% IFD and support factor...
