Title:
BIODEGRADABLE NON-WOVEN FABRIC AND METHOD FOR PRODUCING MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2022/176741
Kind Code:
A1
Abstract:
The present invention provides: a biodegradable non-woven fabric that is biodegradable, is excellent in terms of uniform moldability and shapability (obtaining, in a shorter time, a neat molded body with no tearing, nap, or stretching irregularities), and which has favorable dimensional stability after molding; and a method for producing a molded body. A biodegradable non-woven fabric according to the present invention comprises fibers containing a biodegradable thermoplastic resin, and is characterized in that: the basis weight is 10-450 g/m2 ; the difference between the melting point and the crystallization onset temperature of the non-woven fabric is not less than 91°C; and the cold crystal enthalpy heat quantity ΔH of the non-woven fabric is not less than 1.0 J/g.
