摘要: A yarn of a synthetic, fibre-forming, polymeric material comprising a plurality of filaments having a substantially rectangular cross-section and having a birefringence assymetry across the width of the filaments, each of the filaments being twisted about the longitudinal axis of the filament in such a manner that the overall lateral dimension of the twisted filament corresponds substantially with the length of the rectangular cross-section of the filament.
摘要翻译: 一种合成纤维形成聚合物材料的纱线,其包含多个长丝,其长丝截面基本上为矩形,并且在长丝的宽度上具有双折射成比例,每根长丝围绕长丝的纵向轴线扭曲 这种方式使得绞合丝的整个横向尺寸基本上与长丝的矩形横截面的长度相对应。
