Title:
BIODEGRADABLE LATENT-CRIMPING CONJUGATE FILAMENT AND NONWOVEN FABRIC MADE OF THE FILAMENT
Document Type and Number:
Japanese Patent JP3247176
Kind Code:
B2
Abstract:
PURPOSE: To provide a conjugate filament having biodegradability, excellent mechanical strength, dimensional stability, stretchability and bulkiness, high softness and hot-bonding property and capable of forming a nonwoven, woven or knit fabric suitable as a material for sanitary material and life-relating material.
CONSTITUTION: The objective filament is a biodegradable latent-crimping eccentric core-sheath conjugate filament exhibiting latent crimping capability and 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. As an alternative, the conjugate filament is a biodegradable latent-crimping side-by-side conjugate filament produced by bonding a biodegradable thermoplastic polymer component having high melting point to a biodegradable thermoplastic polymer component having low melting point in side-by-side state. The subject nonwoven fabric is composed of conjugate filaments having a crimp number of ≥25/25mm and partly bonded with each other by hot- bonding.
