Description

FASTENER TAPE AND A METHOD TO PREPARE THE SAME}

The present invention relates to a fastener tape and a method for manufacturing the same, which can be used in garments and binders, and to each other, to which both sides of the fastener tape are coated on a sheet material with hooks or loops formed thereon, wherein the resin is coated. The present invention relates to a foaming method and a fastener tape according to the present invention, wherein the two sheet members are pressurized by the foaming apparatus according to the present invention to perform the foaming.

A fastener tape, generally called "magic tape" or "sticky", consists of two opposing members each having a hook portion and a loop portion formed on a sheet material woven in a tape shape, thereby forming the hook portion and loop portion forming surface of these two members. When they are in close contact with each other, the hook of the hook part is caught by the ring of the loop part and is used to fix an object to each other or temporarily attach an arbitrary object to each other. Most of the fastener tape is made of fiber. It is widely used as an adhesive member in clothes, shoes and bags.

The conventional fastener tape is made on each sheet material separated from each other by the hook portion and the loop portion, and when the attachment is to be made, the sheet member on which the hook portion is formed and the sheet material on which the loop portion is formed are attached to each other. Hook shape is made of various shapes such as clip shape, mushroom head and hook shape in which one side of the loop is cut in order to obtain greater adhesive force, and the shape of the loop is ring-shaped, spring-shaped and irregularly formed at regular intervals. A ring is formed on the sheet material. In addition, each of the hook portion and the loop portion is formed integrally with the sheet material or woven on the dough of the fiber product woven in the form of a tape, each sheet material is a bar or bonded to the desired position of the fiber product It is used. In the method of performing the above bonding, an acrylic adhesive or a rubber adhesive is bonded between the sheet material and the dough of another textile product. Such bonding forms a thick bonding layer, the adhesive force may be weakened due to frequent peeling of the fastener tape, and there is a problem in that the object to be applied is limited because the adhesive layer is not flexible. In addition, there is a method of sealing and bonding the sheet material formed with the dough and the hook or loop of the textile product without using the adhesive. In this case, when the fastener tape is wound, severe bending occurs, so it is limited to some products.

In general, as the material of the hook portion and the loop portion formed on the sheet material, synthetic fibers made of thermoplastic polymer such as nylon, polyester, and polypropylene are used.

On the other hand, looking at the prior art for the somewhat different from the shape and bonding method of the general fastener tape as described above are as follows.

According to the Republic of Korea Patent Publication No. 97-5146, in the self-adhesive portion for the hook and loop fastener, one side is formed with a base material having a hook or loop and the other side includes a base material to which a pressure-sensitive adhesive is applied, The pressure-sensitive adhesive is composed of a water-based adhesive, the adhesive is to provide a self-adhesive portion for a fastener, characterized in that it is applied to form a plurality of layers on the other surface of the base material, the hook according to the invention Has a ring shape, and the loop has a ring shape with a known shape. The apparatus for forming the adhesive layer of the invention comprises a first coating portion for applying an adhesive layer to the back side of the base material, a first drying portion for drying the adhesive, and a second of the adhesive for covering the first drying layer. A second coating part for applying a layer, and a second drying part for drying the second drying layer. As described above, the manufacturing process for forming the adhesive layer is complicated, and there is a problem in that it is restricted in achieving rapid bonding.

According to Japanese Patent Application No. 49-115105, a hook and a loop are formed together on one surface of a fastener tape, and in order to perform the attachment by using it, they must be positioned to face each other and then faced to each other. This is an alternative to reduce the reduction of the adhesion force due to the decrease in the elastic force when the relying on the hook formed only on one side of the conventional, but the production cost rises because it involves a rather complicated process to manufacture such a fastener tape Bring.

According to Japanese Patent Laid-Open No. 62-90513, unlike the conventional loop shape, a plurality of hooks and loops are formed together in the base material, and the hooks and loops are twisted in a spring shape to be detached when detached in the vertical direction after joining. While the invention has the advantage of increasing mutual adhesion, it is difficult to form a plurality of hooks and loops in the base material, and if the uniform formation of the hooks and loops is not achieved, the overall uniform adhesion is obtained. it's difficult.

As described above, conventionally, each member in which hooks and / or loops are formed on each base material or sheet material is applied by joining or sewing on the workpiece. On the other hand, there has not been found an example developed as a fastener tape that can be repeatedly used for a purpose such as a binder tape that can collectively fasten a plurality of wires or bind packages.

SUMMARY OF THE INVENTION The present invention has been made in view of this point, and an object of the present invention is to improve a conventional fastener tape and to expand the scope of application to a completely new field.

In order to achieve the object as described above, the present invention converts the fastener tape into a tape form that can be self-binding by applying an adhesive resin of a predetermined composition to the back of the tape-shaped sheet material formed with the hook portion and the loop portion, respectively, and bonding them together. I was.
