BIODEGRADABLE CONJUGATE SHORT FIBER AND ITS NONWOVEN FABRIC

摘要

PURPOSE:To obtain biodegradable conjugate short fibers having biodegradability, excellent mechanical strength and dimensional stability, improved thermal adhesion, capable of providing nonwoven fabric useful as a material for sanitary material and a material related to life. CONSTITUTION:Biodegradable conjugate short fibers comprises a core part composed of a high-melting biodegradable thermoplastic polymer component and a sheath part composed of a biodegradable thermoplastic polymer component having a melting point lower than that of the polymer. Nonwoven fabric is made of the biodegradable conjugate short fibers comprising a core part composed of a high-melting biodegradable thermoplastic polymer component and a sheath part composed of a biodegradable thermoplastic polymer component having a melting point lower than that of the polymer wherein the constituent fibers are partially thermally bonded mutually or interlaced in a three- dimensional way.
