Title:
BIODEGRADABLE LATENT-CRIMPING CONJUGATE SHORT FIBER AND ITS NONWOVEN FABRIC
Document Type and Number:
Japanese Patent JP3247177
Kind Code:
B2
Abstract:
PURPOSE: To provide biodegradable nonwoven fabric having excellent mechanical strength, dimensional stability, stretchability, bulkiness, flexibility and hot- bonding performance and suitable as a raw material for hygienic material and life-relating material.
CONSTITUTION: The objective fiber is a biodegradable latent-crimping eccentric core-sheath conjugate short fiber 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 fiber is a biodegradable latent-crimping side-by-side conjugate short fiber 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 nonwoven fabric is composed of conjugate short fibers having a crimp number of >25/25mm and partly heat- bonded or three-dimensionally interlocked with each other.
