Abstract: A composite fiber having elastomer and method for making the same, and a substrate having the composite fiber and method for making the same are provided. The composite fiber includes a first composition and a second composition. The first composition is thermoplastic non-elastomer, and the second composition is thermoplastic elastomer (TPE). The second composition is in an amount of 5 to 70 weight % of the composite fiber. The first composition and the second composition are alternately distributed in a circumference of a cross-section of the composite fiber, and the length of the second composition is less than 50% of the total length of the circumference. The TPE can be dispersed uniformly and increase the adhesion between fibers, and the segmented fiber cross-section thereof further prevents the TPE from becoming too adhesive and affecting the processing during the fabrication of fibers and non-woven fabric substrates. Therefore, the non-woven fabric substrate or artificial leather made from the composite fiber has excellent textile feeling and physical properties.

Abstract translation: 提供了具有弹性体的复合纤维及其制造方法，以及具有该复合纤维的基材及其制造方法。 复合纤维包括第一组合物和第二组合物。 第一组合物是热塑性非弹性体，第二组合物是热塑性弹性体（TPE）。 第二组合物的量为复合纤维的5-70重量％。 第一组合物和第二组合物交替分布在复合纤维的横截面的圆周上，第二组合物的长度小于圆周总长度的50％。 TPE可以均匀分散并增加纤维之间的粘合力，并且其分段纤维横截面进一步防止TPE变得太粘并且影响在制造纤维和无纺布基材期间的加工。 因此，由复合纤维制成的无纺布基材或人造革具有优异的纺织感觉和物理性能。

Abstract: A thin and high strength composite laminate includes a fabric, an elastic layer and a water-based polyurethane layer. The fabric is weaved by high-tenacity filament or high-tenacity monofilament. The high-tenacity filament or high-tenacity monofilament is made of polyethylene terephthalate (PET). The fabric has a first surface and a second surface opposite to the first surface. The elastic layer is laminated on the first surface of the fabric. The water-based polyurethane layer is laminated on the second surface of the fabric. In this way, a thin, anti-fouling, abrasion resistance and high physical strength composite laminate can be manufactured.
