COMPOSITE STAPLE FIBER AND PROCESS FOR PRODUCING THE SAME |
摘要 |
<p>A composite staple fiber, wherein a polymer component A and a polymer component B are alternately arranged in a fiber horizontal cross-section; the fiber periphery is entirely covered with the polymer component A; both the polymer component A and the polymer component A have a substantially flat shape; the lengthwise ends of the polymer component B are located 0.05 to 1.5 mu m from the fiber surface; and the weight ratio of the polymer component A to the polymer component B is from 90/10 to 10/90. The composite staple fiber of the present invention is not peeled or split by a carding and a needle punching treatments, but is divided and split in the subsequent water jet entanglement, resulting in flat ultrafine fibers having a sharp-edged structure. <IMAGE></p> |
