Problems solved by technology

And, when this tensile stress is removed after bonding, the slit 11B of the opening tends to close and the sheet main body 10A shrinks in the unwinding direction, so that the skin material is easy to wrinkle.

Embodiment 1

[0104] (manufacture of laminated body)

[0105] use Figure 4 , Figure 5 A device is used to bond the skin material 20 to the surface of the base material 10 to manufacture the laminated body 30A. Details are given below.

[0106] First, the following materials were used as the base material 10 and the skin material 20 .

[0107] (substrate)

[0108] Material: Polyurethane ("VQBN" manufactured by Bridgestone Corporation)

[0109] width direction (with Figure 4 , Figure 5 The length in the direction perpendicular to the feeding direction of the base material): 1500mm

[0110] Thickness: 10mm

[0111] The length of the slit: 5mm

[0112] The extension direction of the slit: Figure 4 , Figure 5 The feeding direction of the substrate in the (first direction)

[0113] (skin material)

[0114] Material: Cloth ("KTM9605" manufactured by TOYOBO CO., LTD.)

[0115] width direction (with Figure 4 , Figure 5 The length in the direction perpendicular to the feeding ...

Embodiment 2

[0149] The test was performed in the same manner as in Example 1 except that the thickness of the base material was 15 mm. The results are shown in Table 1.

Embodiment 3

[0151] The test was carried out in the same manner as in Example 1, except that the base material 10 and the surface material 20 were bonded together using an emulsion adhesive as described below instead of flame bonding.

[0152] That is, the base material 10 is fed out from the roll 1 for base materials, and the skin material 20 is fed out from the roll 2 for skin materials.

[0153] On the upper surface of the substrate 10 sent out from the substrate roll 1, use an adhesive application roller with an emulsion adhesive (acrylic emulsion "NIPOL LX854EX" manufactured by Japan "Zeon" Co., Ltd.) attached to the surface. Spread coating (coating amount: 30g / m 2 ) adhesive, and then make the substrate 10 and the surface material 20 pass between the pressing rollers 4 and 5, so that the substrate 10 and the surface material 20 are bonded together.

[0154] The results are shown in Table 1.

Abstract

A molded product obtained by molding a laminate which comprises both a stretchable substrate that consists of a sheet-shaped synthetic resin foam and that is provided with multiple slits and a stretchable surfacing material laminated on at least one surface of the substrate, characterized in that the stretchable substrate is bonded to the stretchable surfacing material in such a manner that at least some of the slits are kept opened.

Description

technical field [0001] The present invention relates to a substrate made of a sheet-like synthetic resin foam (foam), a molded body formed by molding a laminate having a skin material adhered to at least one surface of the substrate, and a molded body having Clothing of the molded body, a method for producing a laminate, and a method for producing a molded body. Background technique [0002] For clothing items such as bra pads, laminates are used in which a skin material made of cloth is laminated on a skin material of a base material made of flexible polyurethane foam (Patent Documents 1, 2, and 3 below). [0003] In paragraphs 0011 and 0012 of Patent Document 1 (Japanese Patent Laid-Open No. 2006-348423 ), it is described that there are stretchable soft outer polyurethane foams, soft inner polyurethane foams, and non-stretchable foams between them. The laminated body constituted by nature was thermoformed into a bowl shape. [0004] In paragraphs 0009 to 0011 of Patent D...
