Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for attaching a fastener to a cloth made by knitting and weaving fiber yarns used for general industrial materials.

[0002]

2. Description of the Related Art It has been well known that a cloth woven or knitted from a fiber yarn has been used for applications such as a curtain for preventing pollution, a cloth for civil engineering materials, a spun bond and a cloth for construction materials. In these applications, a fabric woven or knitted using spun yarn or long fiber yarn such as vinylon, polyamide, polyester, and aramid fiber is used, and in general, it can be arbitrarily adjusted in the length direction. In the width direction, the width of the knitting loom is substantially determined and is constant. However, there are many applications in which the length is required also in the width direction, and as a method for connecting cloths to each other, there are sewing, overlapping of end portions, and a method of forming holes at the end portions and tying them with a rope or the like. Adjusting the width by sewing is excellent in the strength of joining the cloths, but it is difficult to make fine adjustments at the construction site. When the edges are overlapped, the strength of joining the fabrics together is weak. In addition, there are methods for forming holes through which ropes, etc. are systematically formed during weaving and weaving, and methods for melting by heating, but it is difficult to maintain the shape of the holes themselves when tension is applied to those parts with ropes, etc. Is. Therefore, the vicinity of the hole of the cloth is hung, and a gap is formed between the cloths, so that not only a sufficient effect as a sheet cannot be obtained, but also the appearance quality is deteriorated. Further, as a method of forming a hole through which a rope or the like is inserted, there is a method of mounting a fastener, but in the case of a cloth not coated with vinyl chloride resin, the fastener cuts the fiber yarn at the end, The fiber yarn comes out from the fitting portion, and problems such as reduction in fitting strength occur.

In particular, as a construction sheet made of cloth for building materials, there is a sheet (for example, JP-A-6-146134) which is not covered with a vinyl chloride resin in consideration of environmental problems in recent years. When these sheets are stretched on a temporary structure, a fastening tool is attached to the end of the fabric and fixed to a column such as a pipe with a rope or the like. Since the fiber is cut, the fiber yarns are pulled out from the fitting portion, and the fitting strength is lowered, so that the fitting tool comes off and the end portion of the sheet is deformed.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been made in view of such a situation as described above, and when a fastener is attached to a cloth made by knitting and weaving from fiber yarns, the deformation of the end portion of the cloth is caused. It is an object of the present invention to provide a method of mounting a fastening tool that can reduce the number of fastenings and improve the fastening strength.

[0005]

The present invention achieves the above object and has the following structure. That is, the present invention provides a method of mounting a fastening tool, characterized in that at least one surface of a portion within 20 cm from the end of the cloth is coated with a synthetic resin, and the fastening tool is mounted on the synthetic resin-coated portion. To do.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below. The cloth in the present invention is made by spinning natural fibers such as cotton, hemp and wool, regenerated fibers such as rayon and cupra, semi-synthetic fibers such as acetate and synthetic fibers such as polyamide, polyvinyl alcohol, polyester, polyacrylonitrile, polyethylene and polypropylene. Either a yarn or a long fiber yarn may be used, and it means a knitted fabric woven and knitted using these fiber yarns.

Further, a cloth provided with a synthetic resin in an amount of 5% by weight or less in order to fix the woven and knitted structure may be used.
If the synthetic resin is added in an amount of more than 5% by weight, the texture of the fabric itself may be impaired, preferably 2% by weight.
It is as follows. Also, a hot-melt type fiber yarn having a synthetic resin having a melting point of 180 ° C. or less on its surface and 200
It may be a cloth woven or knitted using a mixture of fiber threads made of a synthetic resin having a melting point of ℃ or more. When such a hot melt type fiber yarn is used, the woven and knitted structure is fixed by heat treatment in a temperature range in which a synthetic resin having a low melting point is melted. The hot-melt type fiber yarn having a synthetic resin having a melting point of 180 ° C. or less on the surface means that a synthetic resin having a melting point of 180 ° C. or less is present on the surface and is composed of a single component. Also, it may be one obtained by composite spinning of two or more kinds of components, for example, a composite fiber yarn having a core-sheath structure.

In the present invention, at least one side of the cloth within 20 cm from the end is covered with the synthetic resin. This resin coating is to prevent the tissue from collapsing and deforming the fabric when the force is applied to the fastening tool, or to prevent the fastening tool from falling off. Depending on the degree, either one side may be resin-coated or both sides may be resin-coated. Further, when the sewing as shown in FIG. 2 is performed to reinforce the end portion, the above resin coating is performed after the sewing, but when the end portion is not required to be reinforced, after cutting according to the application, Resin coating may be performed.

In the present invention, the size of resin coating is
It should be larger than the size of the fastener used. If the part to be fitted with the fastener can be determined in advance, it is possible to coat only that part with a resin, but since the fastener is generally attached to a part within 20 cm from the end, Before mounting, the entire part within 20 cm from the edge may be coated with resin.

The synthetic resin used for coating in the present invention includes polyamide, polyester, polyethylene, polyvinyl alcohol, polypropylene and the like, and is not particularly limited to polyurethane, acrylic ester resin and copolymers thereof, and the like. A synthetic resin that exhibits good adhesiveness to the synthetic resin forming the yarn is preferable. Further, as an additive, a cross-linking agent, a stabilizer, a plasticizer, a flameproofing agent, a pigment, glass beads, an ultraviolet absorber or other additives may be added. However, in consideration of environmental problems and recyclability, it is preferable to use a resin having the same composition as that of the fiber yarn forming the cloth. The property of the synthetic resin is not limited, and may be a solid substance such as a liquid substance, a liquid substance dissolved in a solvent, a paste substance, or a film substance.

The method of coating, the method of coating by hand, the method of spraying, the method of coating such as dot coating or gravure coating, and the mechanical method such as printing are not particularly limited.

In the method of sticking the film, an adhesive or the like may be used for adhering to the fiber cloth, or a hot-melt film for adhering by heating in the subsequent step may be used.

The fastener is not particularly limited, and may be a commonly used metal fastener, but in view of environmental problems and recyclability, the same resin as the fiber thread forming the cloth is used. Desirably configured.
The present invention has the above configuration.

[0014]

[Function] 20 cm from the end of the fabric woven and knitted with fiber yarn
By covering the inside with a synthetic resin and attaching a fastener to the resin-coated portion, not only the decrease in the fastening strength caused by the fiber yarn coming out from the fastening portion is prevented, but also the sheet Deformation of the ends can also be avoided.
