Description

[Detailed description of the invention]

[Industrial Application Field] The present invention applies thermoplastic elastomer and vulcanized rubber to fabrics suitable for use in the field of secondary processed products such as immersion suits, life rafts, boats, vests, and other bag-like bodies. The present invention relates to a fabric whose adhesive strength has been significantly improved, and a method for adhering and joining the fabric. [Prior art] Conventionally, the fabric with a thermoplastic elastomer layer is made of a fabric made of nylon or polyester fiber, and a synthetic resin such as soft vinyl chloride, urethane, or vinyl acetate, and pigments, deterioration inhibitors, lubricants, etc. Those in which a blended elastomer is formed on one or both sides are used. When manufacturing secondary products using these fabrics, the fabric is cut and then welded using a high-frequency welder, high-frequency sewing machine, ultrasonic sewing machine, etc. according to the shape of each product's parts. . Furthermore, in the case of rubber-coated fabrics, secondary products have been manufactured by welding them almost exclusively using solvent-based adhesives. [Problems to be Solved by the Invention] Conventional drawn fabrics are fabrics made only of thermoplastic elastomer or rubber layer, so there are problems in adhesion between the fabric and thermoplastic elastomer or rubber.
When manufacturing secondary products, there are restrictions on the selection of materials for parts such as valves and sponges to be attached to the fabric, making the secondary products extremely expensive and causing various problems in terms of functionality. For example, thermoplastic urethane has drawbacks such as poor adhesiveness. In addition, when attaching parts after manufacturing a bag-like item, the parts sandwiched by the welder's electrodes are all welded together, making the work extremely difficult. Unless a mold release sheet is inserted between the parts, the bag-like part will be welded to the part, and such welding cannot be prevented. The present invention eliminates the above-mentioned conventional drawbacks and relates to a strong drawn fabric in which the fabric is completely integrated with a thermoplastic elastomer layer on one side and a rubber layer on the other side, and the drawn fabric of the present invention. The object of the present invention is to provide an adhesion method using the drawn fabric of the present invention, which allows easy adhesion and joining in the production of secondary processed products. [Means for solving the problem] The first invention of the present invention has a vulcanizable rubber layer on one side,
A fabric with a thermoplastic elastomer layer formed on the opposite side is heat-treated to vulcanize the vulcanizable rubber layer, and at the same time a thermoplastic elastomer layer and a rubber layer are bonded to the fabric. The second invention relates to cloth, and the second invention involves manufacturing a secondary product using the cloth of the first invention, by making the surfaces of the same material of the cloth face each other, and applying a welder and, if necessary, an adhesive. This is a method of adhesion and bonding by using them together. In addition, the third invention involves welding the thermoplastic elastomer layers of two sheets of cloth with each other through a V-shaped or U-shaped sheet of cloth, with the vulcanized rubber layer side facing inside. This method uses the surface of the vulcanized rubber layer as a release layer and uses a welder to adhere the fabric without using a separate release sheet as in conventional methods. Furthermore, the fourth aspect of the present invention is that when a thermoplastic resin component is bonded to a drawn fabric, heat treatment is performed in advance.
At the same time as the rubber layer is vulcanized, the thermoplastic elastomer and the fabric are bonded together, and then the thermoplastic resin parts are bonded to the thermoplastic elastomer layer side of the drawn fabric by welding, or further according to the present invention. 4. In the embodiment of the invention, when parts other than thermoplastic resin parts are adhered to the drawn fabric, after each part is adhered to the rubber layer using an adhesive,
This is a method of bonding fabrics by placing a thermoplastic elastomer layer of another fabric facing the thermoplastic elastomer layer and bonding the thermoplastic elastomer layer of another fabric by welding. Any thermoplastic elastomer can be used as the thermoplastic elastomer used in the present invention, but thermoplastic synthetic resin elastomers such as thermoplastic urethane-based, vinyl-based, ester-based, and nylon-based elastomers are particularly suitable. In addition to natural rubber, chloroprene, and rubber, vulcanizable rubbers include common synthetic rubbers such as styrene-butadiene rubber, acrylonitrile rubber, isoprene rubber, ethylene propylene rubber,
Butadiene rubber etc. can be used. Further, as the rubber adhesive, conventional rubber glue is suitably used. [Function] The present invention provides a rubber layer to be vulcanized on one side of a fabric and a thermoplastic elastomer layer on the opposite side, and simultaneously vulcanizes the rubber layer to be vulcanized and fuses it with the thermoplastic elastomer layer by heat treatment. Because the vulcanized rubber layer, fabric, and thermoplastic elastomer layer are tightly bonded and bonded together, the fabric of the present invention has a higher resistance to bonding of the vulcanized rubber layer to the fabric than conventional fabrics. It is also robust because the adhesive strength of the thermoplastic elastomer layer is high. Furthermore, when manufacturing secondary products using the drawn fabric of the present invention, since the fabric is manufactured by bonding thermoplastic elastomers together, manufacturing of the secondary products is extremely simple, and the fabric is durable. A secondary processed product is manufactured using the fabric of the invention. [Example] Example 1 Using 210d continuous yarn, using a nylon cloth with 60 warp threads and 60 weft threads, Desmodille R
(Desmodur®) (trade name of polyisocyanate adhesive manufactured by Bayer AG), apply a 2% toluene solution to one or both sides of the nylon cloth, apply the rubber glue () shown in Table 1 below on one side, and dry. let After applying co-glue () for thermoplastic elastomer on the opposite side and letting it dry, apply rubber compound () to the side with rubber glue and compound () to the thermoplastic elastomer side using a calendar on both sides of the cloth. Each layer is formed to a thickness of about 0.07 to 0.3 mm. Alternatively, formulation () and/or formulation () may be dissolved in a solvent to form a rubber layer using a sizing machine. The above-mentioned cloth is then passed through a heating oven at 160° C. for 10 minutes to cause a crosslinking reaction, and a vulcanized rubber layer and a thermoplastic elastomer layer are adhered to both sides of the nylon cloth to produce a raw cloth. The fabric thus produced is used for adhesion or welding as shown in FIGS. 1 to 3.

〔Effect of the invention〕

The effects of the present invention can be summarized as follows. (a) The drawn fabric of the present invention has a vulcanizable rubber layer on one side and a thermoplastic elastomer layer on the other side,
Because the rubber layer and thermoplastic elastomer layer are bonded and welded to the fabric through simultaneous heat treatment, the rubber layer and thermoplastic elastomer layer have great adhesion and are extremely durable, making it ideal for immersion suits, Suitable as a material for life rafts. (b) Due to the above structure, when manufacturing secondary products, it is possible to easily and firmly bond by welding only, using an adhesive, or a combination thereof.
Bonding is possible. (c) When manufacturing secondary products with metal parts bonded using the fabric of the present invention by welding, the fabric can be welded as is without using a release sheet etc. as in the past. The product has an excellent finish and does not cause any trouble.
