    • PURPOSE:To manufacture the titled fiber having silky rustle and elegant luster, etc., by forming a composite fiber composed of thermoplastic polymers wherein a specific part of the circumference of the cross-section is made of an easily soluble polymer, and removing a part of the easily soluble polymer to form a groove on the surface of the fiber. CONSTITUTION:A composite fiber composed of two kinds of thermoplastic polymers (preferably polyesters) having different solubilities and having uneven thickness along the longitudinal direction is prepared beforehand. In the circumference of the cross-section of the above fiber, the polymer having higher solubility accounts for two or more parts each having a length of 0.2-4mu. The objective fiber having grooves of 0.2-4mu in the opening width and 0.1-1.8mu in depth can be manufactured by dissolving and removing at least a part of the easily soluble polymer from the composite fiber. The fiber has preferably an irregular cross-section when the grooves are assumed to be absent.
    • 目的:通过形成由热塑性聚合物组成的复合纤维来制造具有丝质沙沙和优雅光泽的标准纤维,其中横截面的周长的特定部分由容易溶解的聚合物制成,并且除去部分 的容易溶解的聚合物在纤维的表面上形成凹槽。 构成:预先制备由两种具有不同溶解度并且沿纵向具有不均匀厚度的热塑性聚合物(优选聚酯)组成的复合纤维。 在上述纤维的横截面的圆周上,具有较高溶解度的聚合物占两个或更多个,其长度为0.2-4mu。 通过从复合纤维中溶解除去至少一部分容易溶解的聚合物,可以制造开口宽度为0.2-4mu,深度为0.1-1.8μm的凹槽的目标纤维。 当假设凹槽不存在时,纤维优选具有不规则的横截面。
