Title:
NONWOVEN FABRIC LAMINATE FOR FOAM MOLDING, COMPLEX OF URETHANE FOAM-MOLDED BODY USING SAID NONWOVEN FABRIC LAMINATE, AND METHOD FOR MANUFACTURING NONWOVEN FABRIC LAMINATE FOR FOAM MOLDING
Document Type and Number:
WIPO Patent Application WO/2013/176176
Kind Code:
A1
Abstract:
[Solution] A nonwoven fabric laminate for foam molding according to the present invention is characterized in that: a reinforcement layer is provided on at least one surface of a dense layer; the dense layer is a nonwoven fabric having a bulk density of greater than or equal to 0.1g/cm3 and comprising polyester-based long fibers that have a fiber diameter of 10 - 30µm and that are fused to each other by means of melt blowing; the reinforcement layer is a nonwoven fabric comprising polyester-based short fibers that have a fiber diameter of 10 - 30µm; and the laminate is obtained by a needle punch interlacing the dense layer and the reinforcement layer. [Effect] The nonwoven fabric laminate for foam molding according to the present invention is capable of maintaining the density inside a seat even after heating, expansion, and shrinkage. The nonwoven fabric has superior mold-following properties during heating, expansion, and shrinkage. The nonwoven fabric laminate can be processed into complex shapes. The nonwoven fabric laminate can be processed well into shapes suitable to molds for foam-molded bodies, and the like, without cutting, and a sufficient density can be maintained on all surfaces of the nonwoven fabric laminate.
