[Industrial Application Field] The present invention relates to an integrally formed laminate molded product that can be used as a structural material for, for example, a camera soft case, a Boston bag, various bags, and a hat. [Prior Art] Conventionally, soft cases for cameras, Boston bags, etc. have used vinyl chloride sheets, polyurethane sheets, natural leather, etc. as outer materials, and have used, for example, brushed fabric, urethane foam, etc. as inner linings. Both sheets were cut and sewn together to create a back. If necessary, parts may be molded or pasted together. [Problems to be Solved by the Invention] As described above, manufacturing bags using conventional materials requires steps such as cutting, sewing, partial molding, and bonding, which is time-consuming. These steps require skill, and it takes years to achieve a beautiful finish. Another disadvantage is that it is not suitable for mass production. The present invention aims to solve these problems and provide a laminated molded product that can be mass-produced beautifully and inexpensively by integrally molding bags and the like. [Means for Solving the Problems] A laminate molded product to which the present invention is applied in order to solve the above problems will be explained with reference to figures corresponding to examples. The laminate molded product of the present invention is a mixture of the facing material sheet 2 and fibers having different melting points with a cotton basis weight of 200 to 600 g/m 2 and containing 10 to 60% by weight of low melting point thermoplastic fibers,
A needle-punched nonwoven fabric sheet 3 with a thickness of 2.0 to 3.5 mm is laminated and heated and compressed to a thickness of 0.9 to 1.3 mm to be integrally formed. [Function] In the laminated molded product of the present invention, a laminated molding material 1 as shown in FIG. 1 in which a facing material seed 2 and a nonwoven fabric sheet 3 are laminated is integrally molded by heating and pressure. Because it contains an appropriate amount of low-melting-point thermoplastic fibers, molded products (bags, etc.) maintain their shape appropriately while providing a soft feel. It is also lightweight. [Examples] Examples 1 to 5 of laminated molded products to which the present invention is applied will be described in detail below with reference to FIGS. 1 to 3. Note that Comparative Examples 1 to 4 are examples of laminate molded products to which the present invention is not applicable. Example 1 Needle-punched nonwoven fabric sheet 3 with a melting point of 130°C, 3 denier x 64 mm polyethylene/polypropylene composite fiber 30% by weight and regular polyester fiber 3 denier x 51 mm 70% by weight, cotton basis weight 350 g/m 2 and thickness 3.5 mm A heat-resistant polyvinyl chloride film (facing material sheet 2) having a thickness of 200 μm is laminated on one side of the molded material 1 with a synthetic rubber adhesive to obtain a molded laminate material 1 having a weight of 610 g/m 2 . After heating this laminated molding material 1 under appropriate conditions, it is placed in a female mold 6 as shown in FIG. 2, and pressure P is applied to the mold 5 to perform press molding. Then, the thickness of the laminated molding material 1 decreases, and a molded article based on the laminated molding material 1 as shown in FIG. 3 is formed. The wall thickness of this molded product is approximately 1.1mm.
become. Example 2 A needle-punched nonwoven fabric sheet 3 is composed of 30% by weight of low melting point fibers (polyethylene/polypropylene composite fibers) and 70% by weight of ordinary polyester fibers, and has a cotton basis weight of 200 g/m 2 and a thickness of 2 mm. A molded article is otherwise produced under the same conditions as in Example 1. The wall thickness of the molded product will be approximately 0.9mm. Example 3 Needle punched nonwoven fabric sheet 3 is made of low melting point fiber 40
% by weight and 60% by weight of ordinary polyester fiber, and has a cotton basis weight of 400 g/m 2 and a thickness of 4 mm. A molded article is otherwise produced under the same conditions as in Example 1. The wall thickness of the molded product is approximately 1.2mm. Example 4 Needle punched nonwoven fabric sheet 3 is made of low melting point fiber 10
% by weight and 90% by weight of ordinary polyester fiber, and has a cotton basis weight of 300 g/m 2 and a thickness of 3 mm. A molded article is otherwise produced under the same conditions as in Example 1. The wall thickness of the molded product is approximately 1.3mm. Example 5 Needle punched nonwoven fabric sheet 3 is made of low melting point fiber 60
% by weight and 40% by weight of ordinary polyester fiber, and has a cotton basis weight of 300 g/m 2 and a thickness of 3 mm. A molded article is otherwise produced under the same conditions as in Example 1. The wall thickness of the molded product is approximately 1 mm. Comparative example 1 Needle punched nonwoven fabric sheet 3 is low melting point fiber 30
% by weight and 70% by weight of normal polyester fiber, has a cotton basis of 150 g/m 2 and a thickness of 1.5 mm. A molded article is otherwise produced under the same conditions as in Example 1. The wall thickness of the molded product is approximately 0.7mm. Comparative Example 2 Needle punched nonwoven fabric sheet 3 is made of low melting point fiber 7
% by weight and 93% by weight of ordinary polyester fiber, has a cotton basis weight of 350 g/m 2 and a thickness of 3.5 mm. A molded article is otherwise produced under the same conditions as in Example 1. The wall thickness of the molded product will be approximately 1.5mm. Comparative example 3 Needle punched nonwoven fabric sheet 3 is a low melting point fiber 65
% by weight and 35% by weight of regular polyester fiber, has a cotton basis weight of 350 g/m 2 and a thickness of 3.5 mm. A molded article is otherwise produced under the same conditions as in Example 1. The wall thickness of the molded product will be approximately 0.8mm. The performance of each example is compared using the table below. As can be seen from the table, the thickness was reduced by molding the laminated molding material 1, and the thickness of the molded product was finished as described. The reduction in thickness occurs when the nonwoven fabric sheet 3 is compressed, and the larger the cotton basis weight of the needle punched nonwoven fabric sheet 3, the thicker the molded product will be.
The lower the cotton weight, the thinner the finish. Furthermore, the flexibility of the molded product changes depending on the ratio of low melting point fibers in the needle punched nonwoven fabric sheet 3. If the ratio of low-melting point fibers is too high, the molded product will be hard and will not have a soft feel, and if it is low, it will become soft and deformed by the application of even a slight external force.
