Document Type and Number:
WIPO Patent Application WO/2022/107986
Kind Code:
A1
Abstract:
The present invention relates to a fabric based on biodegradable cellulose and a method for manufacturing same, the method comprising the steps of: preparing a natural cellulose non-woven fabric including a natural biodegradable raw material; preparing a coating solution including a photopolymerization initiator and a functional additive, and composed of a urethane solution or a silicone solution; applying the coating solution on the natural cellulose non-woven fabric by using a roller containing the coating solution; photopolymerization-molding the natural cellulose non-woven fabric coated with the coating solution; and compressing the photopolymerization-molded natural cellulose non-woven fabric to a predetermined thickness by using a compression roller. The present invention can provide a fabric that can exhibit dust collection and droplet blocking performance through the urethane or silicone coating while maintaining filtering effects through a fiber tissue and a mesh structure, and is eco-friendly due to having excellent biodegradability following disposal. Moreover, the fabric can be used and applied in various filters and separators for secondary batteries by adjusting the weight thereof.
