NON-WOVEN FABRIC FOR INTEGRATING POROUS BASE MATERIAL, PRODUCTION OF NON-WOVEN FABRIC FOR INTEGRATING POROUS BASE MATERIAL, COMPOSITE PRODUCT INTEGRATED WITH THE NON-WOVEN FABRIC FOR INTEGRATING POROUS BASE MATERIAL, AND PRODUCTION OF THE COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To produce a non-woven fabric capable of integrating porous base materials, while maintaining the non-integrated states of the porous base materials, to provide a method for producing the non-woven fabric, to obtain a composite product integrated with the non- woven fabric, and to provide a method for producing the composite product. ;SOLUTION: This non-woven fabric contains ultra fine fibers having a fiber diameter of ≤3μm and comprises two or more kinds of resin components. The non-woven fabric can be formed by binding fiber webs containing dividable fibers capable of being divided into the ultra fine fibers, and simultaneously or subsequently dividing the dividable fibers to generate the ultra fine fibers. The objective composite product comprises the same or different porous base materials and the above non-woven fabric integrally laminated between the porous base materials. The objective composite material can be formed by laminating the above non-woven fabric between the same or different kinds of the porous base materials and subsequently applying ultrasonic waves to at least one side of the laminated product in a liquid-containing state. Therein, the ultra fine fibers of the non-woven fabric are mainly invaded into or entangled with the pores of the porous base material.;COPYRIGHT: (C)1997,JPO
