Document Type and Number:
WIPO Patent Application WO/2012/008169
Kind Code:
A1
Abstract:
Disclosed is a laminate for expansion molding, which has excellent interlayer separation resistance, reinforcing effect and urethane bleeding prevention properties, while being free from powdering on the surface. Specifically disclosed is a nonwoven fabric laminate for expansion molding, which is obtained by laminating a reinforcing layer on at least one surface of a dense layer. The nonwoven fabric laminate for expansion molding is characterized in that the dense layer is obtained by laminating a spun-bonded nonwoven fabric layer (B) on both sides of a melt-blown nonwoven fabric layer (A) and partially bonding the melt-blown nonwoven fabric layer (A) and the spun-bonded nonwoven fabric layers (B) by thermocompression.
