Title:
COMPOSITE MATERIAL CONTAINING BIODEGRADABLE POLYMER, MANUFACTURING METHOD THEREFOR, AND SPUNBONDED NONWOVEN FABRIC CONTAINING COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/153736
Kind Code:
A1
Abstract:
The present invention relates to a composite material containing a biodegradable polymer, a manufacturing method therefor, and spunbonded nonwoven fabric containing the composite material, spinning performance having been improved to allow sufficient cooling and solidification in a limited cooling zone, and heat resistance having been maximized to greatly improve workability in the nonwoven fabric calendering process. In addition, the present invention provides a spunbonded nonwoven fabric having excellent flexibility, mechanical properties and texture by using composite material containing the biodegradable polymer.
