Title:
COMPOSITE MATERIAL COMPRISING BIODEGRADABLE POLYMER, METHOD FOR MANUFACTURING SAME, AND MELTBLOWN NONWOVEN FABRIC COMPRISING SAME COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/153735
Kind Code:
A1
Abstract:
The present invention relates to a composite material comprising: a biodegradable polymer resin; a cellulose fiber; a viscosity modifier; and an acidic catalyst, wherein the cellulose fiber includes a biodegradable polymer that is a surface-modified cellulose fiber. As the composite material comprises a resin having excellent melt flow characteristics, the composite material can be manufactured into a fine fiber and can thus be manufactured into a meltblown nonwoven fabric. As the manufactured meltblown nonwoven fabric has excellent mechanical properties and web uniformity, the meltblown nonwoven fabric may exhibit stable barrier properties when used as a filter and the like.
