Document Type and Number:
Japanese Patent JP5425352
Kind Code:
B1
Abstract:
[Solution] A nonwoven fabric laminate for foam molding of the invention includes a reinforcing layer on at least one side of a dense layer. The dense layer is a nonwoven fabric including polyester continuous fibers with a fiber diameter of 10 to 30 µm and having a bulk density of not less than 0.1 g/cm 3 , the fibers being fusion bonded together by a hot air treatment. The reinforcing layer is a nonwoven fabric including polyester staple fibers with a fiber diameter of 10 to 30 µm. The dense layer and the reinforcing layer are stacked and interlocked with each other by needle punching. [Effects] The nonwoven fabric laminates for foam molding of the invention can maintain denseness in the sheets even after being heated, spread and compressed. The nonwoven fabrics display excellent conformability to the shape of a mold during a shaping process involving heating, spreading and compressing and thus can be formed into complicated shapes. The nonwoven fabric laminates can be advantageously formed into shapes conforming to the shapes of foaming molds or other devices without the need of cutting, and further can maintain sufficient denseness throughout the laminates.
