Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an elastic band in which the hook-to-loop attachment portion does not stretch, and the loop band stretches in the length direction other than the attachment portion. .

(Prior Art) Conventionally, there has been an elastic band in which an elastic loop band and an elastic hook band are engaged, and the hook and loop engagement portion expands and contracts. An elastic band device is shown with a stretchable portion.

(Problem to be solved by the invention) In conventional elastic bands, the elastic loop band and the elastic hook band's hook-to-loop engagement parts stretch together, so there is a risk that the engagement of the loop band will weaken and come off. be.

Further, if the elasticity of the elastic loop band and the elastic hook band are different, wrinkles may occur in the attached portion, resulting in disadvantages such as an unsightly appearance of the attached portion.

(Means for Solving the Problems) The present invention attempts to solve the above-mentioned problems, and as shown in FIG. The warp yarns 2A, 2B, 3A, 2A, 2B, 3A, 3A, 3A, 2B, 3A, 3A, 3A, 3A, 3A, 3A, 3A, 2B, 2B, 3A, 3A, 4B, 3A, 3A, 2B, 3A, 2B, 3A, 2B, 3A, 2B, 3A, 2B, 3A, 2B, 3A, 2B, 3A, 2B, 3A, 2B, 3A, 2B, 3A, 2B, 3A, 2B, 3A, 2B, 3A, 2B, 3A, 2B, 3A, 2B, 3A, 2B, 3A, 3A, 2B, 3A, 2B, 3A,
Loop warps 1A and 1B are arranged in a zigzag manner using multi-fiber bundles of elastic yarn 3B, elastic yarn 4A, and nylon yarn to weave a loop fabric having loops L, and the intersections of each weft and each warp are heat-treated. It is fixed to form a loop band 5A.

By fixing the heat-melting threads of each weft and each warp at the intersection, the hook F consisting of the loop band 5A having the loop L and the non-stretchable hook member 6A is fixed, so that the hooked portion K does not stretch or contract. The attachment part is secure.

Then, the loop band 5A is cut into a predetermined length in the longitudinal direction, and a hook F is attached to the back end 7A of the loop band 5A.
This is a structure in which a non-expandable hook member 6A having a structure is attached.

(Example) The present invention has the following configuration.

As shown in FIG. 1, the wefts 1 to 24 are composed of multifilament bundles of two nylon filaments and two heat-melting threads, and the warps 1A, 1B, 2A, 2B,
3A and 3B are multi-filament bundled yarns of 120 woolly nylon threads and 60 spark nylon (registered trademark) yarns, and the warp yarn 4A is a multi-filament bundle of latex stetron (registered trademark) yarns and 23 nylon yarns. It is made up of bundled threads.

The warp rubber threads 4A are arranged to pass above the weft 1, below the weft 2, above the weft 3, and below the weft 4 in the following order.

The warp 1A (loop warp) passes over the weft 1, over the weft 2, under the weft 3, between the wefts 4 and 5, over the wefts 6, 8, and 10, and under the weft 11, It passes between the wefts 12 and 13, over the weft 14, under the weft 15, over the wefts 18, 20, and 22, and under the weft 23, and is arranged in a zigzag pattern to form a loop L.

Warp 1B (loop warp) passes over weft 1,
Passing over weft yarns 2, 4, and 6, passing under weft yarn 7, between weft yarns 8 and 9, passing over weft yarn 10, and passing through weft yarn 1
1, over the wefts 12, 14, 16, under the weft 17, between the wefts 18, 19, and then the weft 20
It passes over the weft thread 21, passes over the weft threads 22 and 24, and is arranged in a zigzag pattern to form a loop L.

Warp 2A passes over weft 2, under weft 3, over wefts 4 and 6, over wefts 8 and 10, and over weft 1.
, under the weft 12 and 14, under the weft 15, over the weft 16 and 18, under the weft 19, over the weft 20 and 22, under the weft 23, and over the weft 24. It passes over the top and is arranged in a zigzag pattern.

The warp thread 2B passes under the weft thread 1, passes over the weft threads 2 and 4, passes below the weft thread 5, passes over the weft threads 6 and 8, passes under the weft thread 9, passes over the weft threads 10 and 12, and the weft thread 13, above the wefts 14 and 16, below the weft 17, above the wefts 18 and 19, below the weft 21, and above the wefts 22 and 23, and are arranged in a zigzag pattern.

The warp thread 3A passes under the weft thread 1, passes over the weft thread 2, passes under the weft threads 3 and 5, passes over the weft thread 6,
Below wefts 7 and 9, above weft 10, wefts 11 and 13
, above weft 14, below weft 15, 17, above weft 18, below weft 19, 20, weft 2
1, over the weft 22, under the weft 23, and over the weft 24, and are arranged in a zigzag pattern.

Warp thread 3B passes under weft threads 1, 2, and 3, and weft thread 6
It passes above, under the wefts 7, 9, 11, 13, above the weft 14, below the wefts 15, 17, 19, 21, above the weft 22, and below the weft 23.

Since the weft yarns 1 to 24 are filled with heat-melting threads, the heat-melting threads are welded at the intersections of each weft and each warp by heat treatment during finishing, fixing each weft and each warp, and fixing the loop L. loop band 5
A is formed.

The loop band 5A formed by the above structure is cut into a predetermined length in the longitudinal direction, and a non-stretchable hook member 6A having a hook F is attached to the back end 7A of the loop band 5A.

The heat-melting thread of this invention is Toray Elder (registered trademark)
Although thread was used, it is not limited to this as long as it is a heat-melting thread.

Further, the material of the woolly nylon yarn and spark nylon (registered trademark) yarn used for the warp is not limited as long as it is a thermoplastic fiber yarn such as nylon yarn.

Further, as the rubber thread 4A, multi-fibers such as Latex Stetron (registered trademark) thread and nylon thread were used, but any elastic thread such as synthetic rubber thread, natural rubber thread, etc. alone or in combination may be used.

Next, a method of using the elastic band according to the present invention will be explained.

The loop band 5A is cut into a predetermined length in the longitudinal direction, and a non-stretchable hook member 6A having a hook F is attached to the back end 7A of the loop band 5A by gluing, sewing, welder welding, ultrasonic welder welding, etc. It is used as a sock stopper for high socks such as soccer cars, a tourniquet, a watch strap, a binding tool for bundling skis, etc.

(Operation and effect of the invention) The elastic band of the invention is made by weaving a loop L between a weft made of heat-melting yarn and a nylon filament, and a warp made of nylon multi-fiber and elastic thread 4A arranged in a zigzag pattern with the weft. An elastic loop band 5A is formed by fixing the intersecting points between the warp and the warp threads by heat treatment, and a non-extensible hook member 6A having a hook F that engages with the loop band 5A is attached.
The loop body does not stretch or contract, and the attached part K
The engagement is reliable.

It has a feature that the fastening portion K does not expand and contract, but the loop band 5A other than the fastening portion expands and contracts only in the length direction.

Since the engaging portion K of the hook F and the loop L does not expand or contract, the engaging portion K does not wrinkle and has a good appearance.

In addition, in the case of the present invention, unlike conventional elastic bands, there is no need to apply latex to the back of the elastic band to fix the loop thread, so the texture of the back of the elastic band is good. .
