摘要： A composite elastic filament with a rough surface, composed of a sheath component comprising a fiber-forming thermopastic polymer such as polyamide, polyester or polyolefin and a core component comprising a fiber-forming elastomer such as polyurethane or polyester elastomer, wherein the core to sheath compositing ratio ranges from 1/1 to 100/1 in terms of the cross-sectional ratio and the core part has a smooth periphery uniformly extending in the direction of the fiber axis while the sheath part covering the core part has a rough surface wherein numerous ribs are formed in the circumferential direction in proximity to the fiber axis. It can be readily produced by the melt composite spinning of the core and sheath components at the above-specified compositing ratio, followed by stretching 1.1- to 10.0-fold and relaxation. The filament has excellent elastic properties, a small surface friction coefficient and a matting effect due to diffuse reflection of light caused by the rough surface, and is agreeable when worn in the form of a fibrous structure, particularly as lady's stockings.

摘要翻译： 一种具有粗糙表面的复合弹性丝，由包含聚酰胺，聚酯或聚烯烃的纤维形成热塑性聚合物的鞘组分和包含纤维形成弹性体如聚氨酯或聚酯弹性体的核心组分组成，其中芯鞘复合 比例范围为1/1至100/1，横截面比为1：1，纤芯部分具有在纤维轴线方向均匀延伸的光滑周边，而覆盖芯部的外皮部分具有粗糙表面，其中多个肋 沿圆周方向形成在纤维轴线附近。 可以通过以上述规定的合成比例对芯鞘组分进行熔体复合纺丝，然后拉伸1.1-至10.0倍和松弛而容易地制备。 长丝具有优异的弹性，由于粗糙表面引起的光的漫反射而产生的小的表面摩擦系数和消光效果，并且当以纤维结构的形式，特别是作为女士丝袜而被佩戴时，是合适的。
