Problems solved by technology

In the former, since the polyurethane resin film is expensive, the molded foam thus obtained combined with the skin material is also expensive
Meanwhile, the latter has a problem that the hardness of polyethylene foam and polyethylene film affects the molded foam combined with the skin material, thereby unduly increasing the hardness of the molded foam itself
In this step, since the surface to be sewn is made of plastic film, it is hardly smooth, and it is not possible to speed up the sewing

Embodiment 1

[0048] [Formation of foam material protective layer]

[0049] Such as figure 1 As shown, a raw material protection layer 4 comprising a first layer of nonwoven fabric 1, a plastic film 2 and a second layer of nonwoven fabric 3 is formed. Polyurethane spunbonded non-woven fabric (weight per unit area: 12g / m 2 , thickness 50 μm) was used as the above nonwoven fabrics 1 and 3. Furthermore, polyethylene film (weight per unit area: 13g / m 2 , thickness 40 μm) was used as the above plastic film 2, and the nonwoven fabrics 1 and 3 and the resin film 2 were bonded by embossing. At this time, although fine permeation was observed, the waterproof value of the obtained foam material protective layer was 130 mmaq. The peel strength between the plastic film 2 and the second layer of non-woven fabric 3 is 1.6N / 25mm.

[0050] [Formation of skin material]

[0051] refer to figure 2 , firstly the skin (polyester jersey, product of FUKUSHURONSEN) 6 was laminated to one surface of the pla...

Embodiment 2

[0056] First, the skin material obtained in Example 1 was sewn into the target headrest form, and the skin material was arranged in a headrest mold not shown so that the skin of the skin material was in contact with the inner surface of the mold. Then, a frame is inserted, and deformable polyurethane foam raw material is injected through an inlet formed in the skin material, the foam is formed, and cured (for 30 seconds) to obtain a headrest as a molded foam bonded to the skin material.

[0057] The molded foam combined with the skin material obtained in Example 2 has the following effects:

[0058] 1) Since the plastic film 2 is sandwiched between the first non-woven fabric 1 and the second non-woven fabric 3, the molded foam combined with the skin material exhibits very little hardness. Also, since the adhesion between the second nonwoven fabric 3 and the polyurethane foam used as the pad 5 is good, there is no need to use polyethylene foam made of the same resin as the pad...

Abstract

A skin material (7) used in combination with polyurethane foam (8), the skin material (7) comprising a foam material protective layer (4) distributed on the side of the polyurethane foam (8) and Plastic foam (5) and skin (6) laminated sequentially on the protective layer (4), the foam raw material protective layer (4) has at least one layer of non-woven fabric and laminated fabric distributed on the side of the polyurethane foam (8) A plastic film on one surface of a nonwoven fabric.

Description

technical field [0001] The present invention relates to a skin material and molded foam combined with the skin material obtained by integrating the skin material with polyurethane foam; Material. Background technique [0002] Currently, molded foam combined with skin material by integrating the skin material into a cushion material formed of polyurethane foam is used as headrests, armrests, and seat cushions of automobiles, etc. Got it by waiting. [0003] As a skin material that is a component of a conventional molded foam combined with a skin material, a material formed by sequentially laminating a skin, a plastic foam (hereinafter referred to as "cushion"), and a plastic film is used. The reason for using the plastic film here is to prevent the impregnation of the foam material into the liner to form a cured layer during the process of pouring the foam stock into the mold inside which the skin material is placed and then completing the molded foam bonded to the skin mat...
