2. Description of the Related Art A hook-and-loop fastener is made of a knitted or woven fabric in which a hook-shaped engaging element or a mushroom-shaped engaging element and / or a plurality of loop-shaped engaging elements engaged with these engaging elements are provided on a woven base cloth. And a molded surface fastener obtained by extrusion or injection molding. Woven hook-and-loop fasteners are widely used for various applications due to their engaging performance and flexibility due to the weaving structure. Molded hook-and-loop fasteners are low in price and have high engaging force, so they are used for engaging members of industrial materials, diapers and sanitary goods. Used in disposable products.

[0003] The present invention relates to a technique for joining a hook-and-loop fastener to an adherend. When a knitted surface fastener is attached to a fabric, usually, sewing with a thread or joining with various adhesives is performed. On the other hand, there is also a method of joining a woven surface fastener to a resin film or sheet, but in this case, if the adhesiveness between the woven surface fastener and the resin film is inappropriate, the adhesive strength is poor and it is not practical. I will not stand it. Since the molded surface fastener cannot be sewn, it is joined by an adhesive or fusion.

Conventionally, as a resin film or sheet, polyvinyl chloride resin having excellent adhesiveness to a hook-and-loop fastener has been frequently used. However, when the polyvinyl chloride resin is incinerated, a chlorine-containing gas is generated. It is also said to be the cause. Therefore, it has been proposed to use a film or sheet made of a polyolefin-based resin that does not generate toxic gas in place of the polyvinyl chloride resin and bond a hook-and-loop fastener to this film or sheet. Due to poor affinity and adhesiveness, it has a problem that it cannot be strongly bonded to a hook-and-loop fastener.

However, the above-mentioned method involves preparing a two-layer film, slitting the two-layer film to the same width as the hook-and-loop fastener, and the two-layer film having a different hygroscopic property. May need to be bent, a fusing device must be installed, and the heating conditions must be controlled and the thickness of the two-layer film must be adjusted so that the surface fastener and the two-layer film can be fused well. However, the production process is complicated and expensive, and there are many problems in practicality. Further, even if the two-layer film is directly fused to the hook-and-loop fastener, the adhesion is not sufficient, and the film is easily peeled off from the bonding surface, which is not a practical technique. An object of the present invention is to solve the above problem and to provide a surface fastener for fusion in which adhesion between a surface fastener and an adherend such as a polyolefin-based resin film or sheet (hereinafter referred to as a polyolefin-based adherend) is improved. I do.

The fibers constituting the hook-and-loop fastener of the present invention are:
A thermoplastic fiber may be used, but a polyamide fiber or a polyester fiber is preferable in terms of strength, elasticity, deformation recovery property and the like. In the hook-and-loop fastener of the present invention, since the base cloth, the hook-shaped engaging elements and the loop-shaped engaging elements are formed by a weaving method, the fibers of the base cloth and the fibers of the engaging elements are not sufficiently fixed. In the process, the fibers of the base fabric and the engaging element move, and the position of the engaging element may move slightly.
Since the hook-and-loop fastener of the hook-shaped engaging element first forms a large number of loops with a filament on the base cloth and cuts a part of the side thread of each loop with a minute movable blade to form the hook-shaped engaging element. It is important to fix the position of the loop, and it is necessary that the base cloth and the hook-shaped engaging element are sufficiently fixed. Further, it is necessary to prevent the hook-shaped engaging element from moving or coming off from the base cloth by repeating attachment and detachment with the loop-shaped surface fastener.

In the case of the loop-shaped engaging element, it is not necessary to fix the position more strictly than in the case of the hook-shaped engaging element. However, a uniform arrangement is desirable in order to have a uniform engaging force with the hook-shaped engaging element. Since it is desirable that the loop-shaped engaging element does not move or slip off from the base fabric by repeatedly attaching and detaching the loop-shaped engaging element, it is necessary to fix the fibers of the base fabric and the engaging element fibers.

In view of the above problems, the conventional knitted surface fastener has a coating layer provided on the back surface of the base cloth, that is, the side having no engaging element, and the fibers of the base cloth and the hook-shaped or loop-shaped engaging element are provided. The fibers were glued and fixed. Since the resin used for the coat layer is preferably a resin having an affinity for the constituent fibers of the hook-and-loop fastener, the polyurethane resin is preferably used because it has excellent affinity and adhesion with the polyamide or polyester-based fibers forming the hook-and-loop fastener. It is used.

However, such a technique for providing a coat layer requires a resin, and further requires various steps for providing the coat layer. Therefore, a simpler technique has been required. The present inventors have made various studies and found that the problem can be solved by forming the base fabric of the hook-and-loop fastener with fibers containing a low melting point resin and further applying a molten adhesive layer to the back surface of the hook-and-loop fastener. I found it.

As the low melting point resin, a resin having a melting point lower than that of polyamide or polyester can be widely used, and its melting point is preferably about 80 to 150 ° C. Specific examples of the low melting point resin include a copolyamide, a copolyester, and a polyolefin resin. The low melting point resin is desirably contained in an amount of 20 to 60% by weight based on the entire fibers constituting the base fabric. If the amount is less than 20% by weight, the effect of containing the low melting point resin is insufficient, and if it exceeds 60% by weight, the amount of the low melting point resin is too large and the mechanical performance of the base fabric is impaired. More preferably, it is 30 to 60% by weight. Using the low-melting-point resin-containing fiber, a knitted surface fastener is produced in accordance with a conventional method.

In the present invention, a molten adhesive layer is provided on the back surface of the surface fastener, that is, the surface having no engaging element by melt coating. The molten adhesive in the present invention is used for fusing the base fabric of the hook-and-loop fastener and the polyolefin-based adherend, and at the same time, has the effect of a coat layer on the base fabric of the hook-and-loop fastener. That is, the molten adhesive is fused with the low-melting-point resin forming the base cloth, and the base cloth and the fibers forming the engagement element can be sufficiently fused and fixed. In order to have such an effect of the coating layer, the coating layer for the conventional surface fastener can be omitted, and the effect of the molten adhesive for the polyolefin-based adherend can be further provided. Of course, it is also possible to apply other molten adhesives to the molten adhesive of the present invention for additional purposes. From the above object, it is preferable to apply the molten adhesive layer of the present invention at an early stage of the production of the surface fastener, to fix the base fabric of the surface fastener and the engaging element fibers, and to smoothly proceed with the production of the surface fastener.

Since the hook-and-loop fastener of the present invention uses an olefin-based polypropylene thread for the base cloth, it has good adhesion with the EVA hot melt resin of the olefin-based resin, the base cloth and the hook thread are sufficiently fixed, and the loop-shaped surface is formed. The hook did not move or slipped off the base cloth even after repeated attachment and detachment with the fastener.

COMPARATIVE EXAMPLE 1 The hook yarn and the base warp of Example 1 were made the same, and the surface fastener was replaced with a multifilament yarn in which 24 4.6 denier filaments made of nylon-66 were bundled together. Weaved. Then, 100 g / m 2 of an EVA hot melt resin of an ethylene-vinyl acetate copolymer containing 25% of vinyl acetate as the same polyolefin resin as in Example 1 was applied directly to the back surface of the base fabric of the hook-and-loop fastener, followed by fusing. I got a hook-and-loop fastener. The obtained surface fastener was heat-sealed with a high-frequency welder in the same manner as in Example 1. However, the surface fastener was easily peeled off at the interface between the back surface of the base fabric and the EVA hot melt resin, and a surface fastener capable of being fused was prepared. could not. Further, in the hook-and-loop fastener, in the step of forming the hook, the hook was not sufficiently fixed, the hook came off and the hook moved, and the function as a detachable hook-and-loop fastener was also insufficient.
