摘要

(57) Abstract As for this invention, in regard to the method in order to produce the biodegradation characteristic fibril from the biodegradation characteristic homo- polymer or copolymer resin of 1 kinds or more, with that method a) solvation while forming the liquid resin blend by being able to point, the biodegradation characteristic resin b) agitating the non solvent it introduces the liquid resin blend into the non solvent. This invention furthermore regards the biodegradation characteristic fibril which is produced making use of the method of this invention. This invention furthermore regards the nonwoven fabrics which consist of the biodegradation characteristic fibril of this invention. This invention, the water permeable top seat, furthermore regards the absorption core and the disposable absorber which consists of the water impermeability back seat, as for the top seat consists of the non- woven backing material which it is possible from the biodegradation characteristic fibril of this invention. This invention furthermore regards the textile which consists of the biodegradation characteristic nonwoven fabrics of this invention.
