Description

Detailed Description of the Invention The present invention provides a polyethylene sheet consisting of a single layer of polyethylene or a multilayer structure of polyethylene, aluminum, and polyethylene, on the back side of a relatively thick fiber base material such as needle punched cloth or tufted carpet cloth. This relates to a method of obtaining a relatively thick fiber base material lined with a polyethylene resin layer, which is mainly processed into heating carpets with electric wires, etc. by integrating them, and it is difficult to process and handle needle-punched cloth or tufted cloth. To provide a method for integrating a fiber base material and a polyethylene sheet, which allows work to be performed extremely easily and with high efficiency even though a relatively thick fiber base material such as carpet cloth is used. It is something.

Hereinafter, a method of integrating a relatively thick fiber base material and a polyethylene sheet according to the present invention will be explained based on the drawings.

The method of the present invention comprises a base material 1 made of relatively thick elongated fibers such as needle-punched cloth or tufted carpet cloth having a thickness of about 10 mm or less made of fibers such as polyester, nylon, or acrylic; , 1. (Tart Index) A single layer of polyethylene or
A long polyethylene sheet 2 consisting of a multilayer structure of aluminum and polyethylene is laminated with the polyethylene sheet 2 in contact with the back surface of the fiber base material 1, and heated to 100 to 200°C. The polyethylene sheet 2 side is in contact with the surface of the heating roll 4, and the fiber base material 1 and the polyethylene sheet 2 are moved continuously while being pressed for 10 to 60 seconds. A relatively thick fiber base material 5 which is lined with a polyethylene resin layer is obtained.

In the illustrated embodiment, in order to press the laminated sheet 3 against the surface of the heating roll 4, an endless belt 5 is disposed around the heating roll 4, and the pressing force of the endless belt 5 is used to press the laminated sheet 3 onto the surface of the heating roll 4. is pressed against the surface of the heating roll 4, but other suitable pressing means may be used for this purpose.

In addition, in order to prevent the surface of the polyethylene sheet 2 from fusing and adhering to the surface of the heating roll 4,
It is necessary to use one that has been subjected to an appropriate release treatment such as Teflon coating.

The method of integrating a delicate base material and a polyethylene sheet according to the present invention is to melt the polyethylene component of the polyethylene sheet by heating with a heating roll 4 and utilize the thermal welding ability of the molten polyethylene. Since the polyethylene sheet (3) is integrated with the fiber base material, the heating temperature of the heating roll 4 needs to be higher than the melting point of the polyethylene component in the polyethylene sheet used, and is usually 110 to 200'. C! , preferably 120-150
It is best to heat it to around ℃.

As described above, the relatively thick fiber base material 5 lined with a polyethylene resin layer obtained by the method of integrating a fiber base material and a polyethylene sheet of the present invention can be used, for example, on the back side of the fiber base material 5. That is, a carpet backing material in which separately manufactured heating wires are embedded is integrated with the polyethylene resin layer side by means such as hot pressing, and processed into a heating carpet with electric wires inserted therein. Therefore, the surface carpet cloth 2
The polyethylene part that becomes the adhesive layer for the front carpet cloth, the heat transfer homogenizing part 1 containing aluminum, the back carpet part, etc. are integrated by heat press (4) several times using a flat plate heat press. Compared to the conventional production process for heat-generating carpets containing electric wires, the process is extremely simple and can be manufactured with high efficiency, making it possible to obtain heat-generating carpets containing electric wires at a much lower cost. When using a polyethylene sheet with a multilayer structure of polyethylene, aluminum, and polyethylene, even better heat transfer can be achieved simply by integrating the carpet backing material mentioned above on the back side of the resulting fiber base material. Since it can be processed into a heating carpet containing electric wires that has uniformity, it is possible to obtain a heating carpet containing electric wires that is extremely efficient and has excellent heat transfer uniformity.

As described above, the method for integrating a fiber base material and a polyethylene sheet of the present invention is to continuously integrate a long fiber base material and a polyethylene sheet on a heating roll, so that processing is not necessary. Although it uses relatively thick fiber base materials such as needle punch cloth and tough denim carpet cloth, which are difficult to handle, the operation process is extremely simple and the work can be done at high speed. I can do it.

In addition, in the method of the present invention, the polyethylene component of the polyethylene sheet to be integrated into the fiber base material is M, and has a low melting point and low viscosity within the range of 1.10 to 5o. Therefore, it is possible to reliably obtain a laminate in which the polyethylene component of the polyethylene sheet has high heat-sealing performance and the polyethylene resin layer is completely integrated on the back surface of the fiber base material.

In addition, the method of the present invention can be applied to any processing width of the fiber base material and polyethylene sheet by simply selecting the width of the heating roll used, and its range of application is wide. It is.

Furthermore, in the present invention, the fiber base material lined with a polyethylene resin layer can be obtained in a long form, so when it is subjected to the next processing, the state in which the long piece is wound is not changed. Since it can be supplied either as a sheet or as a cut sheet, there is no restriction on the next processing step, and the range of application to processing operations is wide.
