BIODEGRADABLE CONJUGATE FILAMENT AND NONWOVEN FABRIC MADE OF THE FILAMENT

Japanese Patent JP3264719

B2

PURPOSE: To provide a conjugate filament having biodegradability, high mechanical strength and dimensional stability and excellent hot-bonding property and capable of forming a nonwoven fabric suitable as a material for sanitary material and life-relating material.
CONSTITUTION: The objective filament is a biodegradable conjugate filament having a core part composed of a biodegradable thermoplastic polymer component having high melting point and a sheath part composed of a biodegradable thermoplastic polymer component having a melting point lower than that of the core part. The subject nonwoven fabric is composed of biodegradable conjugate filaments having a core part composed of a biodegradable thermoplastic polymer component having high melting point and a sheath part composed of a biodegradable thermoplastic polymer component having a melting point lower than that of the core part, wherein the filaments are partly bonded with each other by hot-bonding.
