CORE-SHEATH TYPE POLYOLEFIN CONJUGATE FIBER AND NONWOVEN FABRIC COMPOSED OF THE SAME FIBER

摘要

PROBLEM TO BE SOLVED: To provide a core-sheath type polyolefin conjugate fiber excellent in spinning stability and capable of providing a nonwoven fabric having soft touch feeling and high strength and free from fuzz and a hot-bonding type nonwoven fabric.;SOLUTION: This (eccentric) core-sheath type polyolefin conjugate fiber is obtained by using a resin composition composed of 98-85 wt.% polypropylene having a specific fluidity and 2-15 wt.% one more kinds of polyethylenes selected from a specific high-density polyethylene, low-density polyethylene, straight-chain low-density polyethylene and polyethylene polymerized by using metallocene catalyst as a core component and using a specific high-density polyethylene or a polyethylene polymerized by using a specific metallocene catalyst as a sheath component. This nonwoven fabric is composed of the above fiber.;COPYRIGHT: (C)2002,JPO
