GESCHAEUMTE POLYOLEFINFASERN UND VERFAHREN ZU DEREN HERSTELLUNG |
摘要 |
Polyolefin foamed fibers consisting of composite fibers having a good spinnability, a small fineness and a non-waxy feeling, and a process for producing the same are provided, which foamed fibers having a structure wherein only a composite component (B) dominantly forming the fiber surface of composite fibers along the direction of the fiber axis thereof is substantially foamed and a part of the resulting foamed cells are burst open on the fiber surface, and which process comprises adding a foaming agent only to the above component (B) and combining two composite components so that the composite ratio thereof is 30/70 or higher and the theoretical average thickness of the component (B) in the cross-section of the unstretched fibers is 2 to 15 microns. |
