らのコスト高は避けられない。 Conventionally, when a needle punching mat is thermoformed and pressure bonded to the surface of a molded substrate, a thermoadhesive film is laminated on the needle punching mat with adhesive or heat fusion in advance, and then the surface of the thermoadhesive film is molded. The method used is to overlap the substrate surface and press-bond it with a mold. This method requires an independent process of laminating a heat-adhesive film onto a needle-punched mat.
Problems with lamination technology and high costs due to the number of steps are unavoidable.

製造方法である。 The present invention uses synthetic fibers, chemical fibers, or a mixture of both of 18 to 30 deniers as web-forming fibers, and deposits the fibers to form a web of 200 g/m 2 or more, and punches the upper surface of the web as the first punching surface. A first punch with a density of 30 to 100 P/cm 2 and a penetration of 12 to 17 m/m is applied, and then a second punch with a punch density of 30 to 100 P/cm 2 and a penetration of 12 to 17 m/m is performed using the back side as the second punching surface. 2. After punching, a thermoadhesive synthetic resin sheet is stacked on the second punching surface, and punched from the opposite side to the first punching surface, with a punch density of 30 to 60P/cm 2 and a penetration rate of 8. This is a method for producing a thermoformable, pressure-bondable needle-punched mat, characterized by performing a third punching of ~12 m/m.

ことに成功した点に特徴を有するものである。 In other words, in the past, a heat-adhesive synthetic resin sheet was laminated onto a needle-punched mat in an independent process separate from the needle-punching process, whereas the present invention combines a needle-punched mat and a heat-adhesive synthetic resin sheet. It is characterized by the success in integrating the layers by needle punching, that is, by incorporating the conventional lamination process into the needle punching process.

件である。 In the present invention, a needle punching mat that can achieve the purpose of thermoforming and pressure bonding to the surface of a molded substrate cannot be obtained by simply laminating and integrating the needle punching mat and a thermoadhesive synthetic resin sheet by simple needle punching. do not have. In other words, the punch density is
The following conditions must be met: 30-60P/cm 2 Penetration 8-12m/m. In other words, in the present invention, the needle-punched mat and the heat-adhesive sheet are bonded together by the fuzz that protrudes from the surface of the heat-adhesive sheet by performing needle punching. However, if the fuzz protrudes too much, the heat-adhesive sheet becomes As a result of over-covering the sheet surface with fluff, the adhesive strength to the molded substrate surface decreases, and on the other hand, if the fluff protrudes too little, it becomes impossible to bond the needle-punched mat and the heat-adhesive sheet. purpose cannot be achieved. In order to solve the above problems and obtain an excellent thermoformable pressure-adhesive needle punching mat, the punch density is 30 to 60P/ cm2 and the penetration is 8 to 12m/m.
This condition is essential and is an important requirement for the configuration of the present invention.

繊維、レーヨン繊維等の中から選定使用される。 In the present invention, instead of bonding the needle-punched mat and the heat-adhesive synthetic resin sheet by adhesive or heat fusion as in the past, the method uses a physical method in which the heat-adhesive synthetic resin sheet and the fluff are entangled. Since the fibers are bonded by mechanical means, there is no need to take into account the adhesion with the heat-adhesive synthetic resin sheet when selecting the web-forming fibers. Although fibers can be used, synthetic fibers and chemical fibers such as polypropylene fibers, nylon fibers, polyester fibers, rayon fibers, etc. are mainly used.

能である。 In addition, as the heat-adhesive synthetic resin sheet, both low melting point sheets such as polyester filament deposited sheets and polyamide films, and high melting point sheets such as polyethylene films and ethylene monovinyl acetate copolymer films are used. When the fibers are polypropylene fibers, for example, a low melting point sheet is preferred. However, in the case of nylon fiber, polyester fiber, rayon fiber, etc., either a low melting point sheet or a high melting point sheet can be used.
