摘要：

为研究组织结构与磨损对织物屏蔽性能的影响，以及不锈钢长丝对织物折皱回复性的影响，使用自制的棉/不锈钢长丝包芯纱织制了3种不同组织的机织物，测试了织物在0.3~1 500 MHz频段上的电磁屏蔽性能，并使用平磨仪对各织物分别摩擦60、120、180、240 及300次后，测试了织物磨损后的电磁屏蔽性能；同时，采用视频序列法测试了织物的动态折皱回复角。结果表明：织物组织结构对电磁屏蔽性能有一定影响，平纹组织结构紧密，屏蔽效果好；经过若干次磨损后，织物的电磁屏蔽性能先小幅升高后逐渐降低；相同磨损条件下，试样耐磨性越好，屏蔽效能的降低幅度越小；由于不锈钢长丝的加入使织物的折皱回复性降低，可以采用浮长更长的组织改善织物起皱现象。

Abstract:

In order to study the electromagnetic shielding properties and wrinkle performance of the cotton / stainless steel filament woven fabrics, cotton/stainless steel filament core spun yarns were used to make three kinds of fabrics, including plain, 1/2 twill, and 1/3 twill weave. The electromagnetic shielding properties in 0.3-1500MHz are compared. After the wear tests for 60, 120, 180, 240 and 300 times on the textile abrasion tester, the electromagnetic shielding properties are also tested and compared. The wrinkle recovery properties are tested by video sequence method. Results shows that, the fabric weaves have some effects on the electromagnetic shielding property. Because of the compact structure, plain fabric has a higher SSE. Through several times of friction, the SSE has a small increase, then decrease gradually. At the same wear condition, samples will have a lower reduction degree of the shielding effectiveness, which have better performance of the wear resistance. Because of the stainless steel filament, the fabrics have lower wrinkle recovery properties. The fabric weaves which have longer float could improve the wrinkle performance.

Key words: stainless steelfilament, electromagnetic shielding, fabric weave, fabric abrasion, wrinkle recovery
