    • Provided are composite fibers comprising a hydrophobic polyester (B) having a moisture absorbency at 20°C, 65% RH of not more than 2% and having a total concentration of at least one metal selected from the group consisting of alkali metals and alkali earth metals of at least 500 ppm and a nylon-4 polymer (A) in an amount of 40 to 80% by weight based on the weight of the fiber. They are excellent for clothing use, since they have excellent moisture absorbency, give no clammy feeling upon absorption of moisture, and do not suffer delamination between the nylon-4 polymer and the hydrophobic polyester. Particularly excellent among them are sheath-core composite fibers comprising a core of the nylon-4 polymer (A) and a sheath of the hydrophobic polyester (B) and side-by-side composite fibers having a flat cross-section in which the nylon-4 polymer and the hydrophobic polyester are bimetal-wise laminated with each other.
    • 提供的复合纤维包括在20℃,65%RH下的吸湿性不超过2%的疏水性聚酯(B)和总浓度为至少一种选自碱金属和碱土的金属 至少500ppm的金属和基于纤维重量的40至80重量%的尼龙-4聚合物(A)。 它们对于服装使用是非常好的,因为它们具有优异的吸湿性,在吸收水分时不产生粘滞感,并且不会在尼龙-4聚合物和疏水性聚酯之间发生分层。 其中特别优异的是包含尼龙-4聚合物(A)的芯和疏水性聚酯(B)的护套和具有扁平横截面的并列复合纤维的皮芯复合纤维,其中尼龙 -4聚合物和疏水性聚酯彼此双金属层压。
