Title:
SPUN-BOND NON-WOVEN FABRIC, HYGIENIC MATERIAL, AND METHOD FOR PRODUCING SPUN-BOND NON-WOVEN FABRIC
Document Type and Number:
WIPO Patent Application WO/2023/190073
Kind Code:
A1
Abstract:
The spun-bond non-woven fabric according to the present disclosure comprises fibers formed from a resin composition. The resin composition comprises a propylene-based polymer (A), a thermoplastic polyurethane-based elastomer (B), and a polymer (C) modified with at least one polar group selected from the group consisting of an oxygen-containing group, a nitrogen-containing group, a sulfur-containing group and a phosphorus-containing group. The ratio of the peak intensity of an α-crystal of the fibers to the crystallinity degree of the fibers is 10.5 or less. The peak intensity of the α-crystal shows a peak intensity of plane (110) of the propylene-based polymer (A) at around 2θ=14° in an X-ray diffraction pattern measured by an X-ray diffraction device using CuKα line.
