[Problems to be solved by conventional techniques and ideas]

Hook-and-loop fasteners generally have a male and female surface combined, but This is a so-called homotype surface flap that combines male surfaces with a stem with a stem as the engaging part. Zippers are also used. Conventionally, the male surface for this homo-type hook-and-loop fastener has a mushroom that is the engaging part. The stem and the base part from which the stem extends are integrally molded with resin. It was not possible to produce large area or long items, resulting in low productivity.

[Means to solve the problem]

The inventors of the present invention aimed to develop a highly productive homotype hook-and-loop fastener, and As a result of continuing intensive research with a focus on using fiber-based materials that can be used to produce products, If the stems with mushrooms planted on the base material are each independent, the engagement force will be weak. Therefore, it is not suitable as a male surface for a homotype, and on the other hand, it is necessary to use a very high surface to increase the engagement force. Considering that it is difficult to plant at high density, the heads of multiple stems are welded together. When I made it into a mushroom shape, surprisingly, it had a moderate relationship as a homotype male mask. They discovered that it is possible to impart compatibility and completed the present invention. That is, the present invention is a male surface for a hook-and-loop fastener using a fiber material, which is embedded in a base fabric. The heads of thermoplastic resin monofilament are welded together in multiple units to create a mash. Male surface for a male-male homotype hook-and-loop fastener characterized by a loom shape and a male-male homotype hook-and-loop fastener having such a male surface as at least one male surface. It is intended to provide

[0005] Referring to FIGS. 1 and 2, conventionally, the male surface for hook-and-loop fasteners is male-male or male-female. Engagement parts, whether hook-shaped or mushroom-shaped The stem (1) that was to become the base part (2) was provided independently. Monov When the filaments are arranged in this way, they can be engaged in male-to-male combinations as shown in Figure 2. However, each of the strands is weak, and the engagement force required for a homotypic male face cannot be obtained. On the other hand, in the male surface for hook-and-loop fasteners of the present invention, as shown in FIGS. (4) The monofilament (3) planted on top has multiple mushroom heads. The feature is that each part is welded together. Weld multiple pieces together like this As a result, these multiple wires behave as a minimum unit when engaged, and as shown in FIGS. 1 and 2. "Strength" is improved compared to when the monofilament is installed independently like the type of As a result, an appropriate engagement force can be obtained as a homotype. Furthermore, multiple However, due to the material used, it cannot be seen on the male side of the homotype that is molded in conventional resin. It has a moderate amount of ``deflection'' or ``flexibility''. As used herein, the term "welded together" refers to multiple Not only when all the parts are welded together, but also when the A mushroom connected to another mushroom through another mushroom It also includes cases. In other words, multiple rods enter the gap between the mating male surfaces as a unit and cannot be engaged. It suffices if it is integrated to the extent that it is possible.

[0006] The number of monofilaments to be welded together is usually 2 to 9, and the entire male surface is The number may be the same, or the number may be different. monofila The thickness of one mento is between 250 and 1300 deniers. The number of these This is because appropriate "deflection" and engagement force can be obtained if the material is thick and thick. Also, The distance between monofilaments to be welded together is usually 1 mm to 1.5 m. The range is m. With this spacing, it is possible to weld them together, and furthermore, within the above range. This is because there is no problem in weaving the monofilament of the same thickness into the base fabric. The manner in which the monofilament is planted on the base fabric is not particularly limited; Because it is easy to weld several pieces together, as shown in Figure 2, it is possible to plant them in groups. It is preferable to In this case, for example, if multiple fibers are planted through one hole in the base fabric, Another example is a mode in which they are dispersed and planted through a plurality of holes in close proximity to each other.

[0007] Next, the material of the monofilament is thermoplastic because it is heat welded during manufacturing. Uses plastic resin. The type of thermoplastic resin is not particularly limited, but Polypropylene and and nylon are preferred, and polypropylene is more preferred. Furthermore, the type of base fabric on which the monofilament should be planted is not particularly limited. For example, bonded double woven fabrics using polyester, nylon or polypropylene fabrics. etc. can be used. The thickness of the base fabric is preferably 2 to 5 mm.

[0008] For example, the homotype male surface for hook-and-loop fasteners of the present invention is produced using the so-called knotted double weave method. The monofilament is woven into two base materials, and the monofilament is woven between the base materials. cut, then heat the tip of the monofilament to melt it somewhat excessively, making each Not only does it give a mushroom shape to the head of the monofilament, but also the adjacent Manufactured by welding the heads of multiple monofilaments together. can. The heating temperature generally makes it easy to form a mushroom shape and weld it together. Considering the properties, the temperature is set in the range of 500 to 600°C. In this way, the advantage of this invention is that it is manufactured using fiber-based materials, so it is difficult to produce long items. is possible, and is superior in productivity to conventional resin-molded one-piece male surfaces.

[0009] The thus obtained male face of the present invention can be used as is or cut into various sizes. , combined with each other to form a homotype hook-and-loop fastener, or according to the present invention. It can also be a homotype in combination with a mushroom-shaped male mask. It takes Homotype hook-and-loop fasteners are also within the scope of the present invention. The homotype hook-and-loop fastener of this invention can be used for building materials, such as ceiling materials and flooring materials. , attaching decorations to walls, or fixing various parts inside a car. It can be suitably used for etc. During use, engagement will occur immediately when both sides touch. This makes positioning work easier. In addition, the engaging part has a moderate amount of "deflection". However, since the engagement is performed randomly, a light engagement can be obtained, and the engagement can be easily performed for another use. can be solved smoothly.
