Title:
LONG-FIBER NON-WOVEN FABRIC WITH EXCELLENT SOFTNESS AND EXCELLENT ABRASION RESISTANCE AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2013/105587
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a long-fiber non-woven fabric with excellent softness and excellent abrasion resistance, particularly, a long-fiber non-woven fabric suitable for a disposable body warmer. This long-fiber non-woven fabric for a disposable body warmer is a thermocompression-bonded, spunbonded non-woven fabric which is manufactured by a spunbond method through thermocompression bonding using a pair of engraved and flat rolls. The thermocompression-bonded, spunbonded non-woven fabric is composed of long fibers which comprise at least 95% of polyethylene terephthalate and which exhibit a birefringence of 0.07 to 0.12, and has a KES bending rigidity of 0.05 to 0.30gf·cm2/cm and abrasion resistance grades satisfying the relationships (1) to (3): E1 ≥ 3 ··· (1); E2 ≥ 1 ··· (2); and E1 - E2 ≥ 1 ··· (3) [wherein E1 is the abrasion resistance grade of the embossed surface of the non-woven fabric, and E2 is that of the other surface thereof which is reverse to the embossed surface].
