Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a woven slide fastener in which a coil-shaped fastener element row made of synthetic resin is woven into one side edge of a fastener tape.

[0002]

2. Description of the Related Art Conventionally, a monofilament made of synthetic resin is bent in a zigzag shape to form a fastener element,
In a slide fastener in which this fastener element is woven into one side edge of a fastener tape, several warp yarns are arranged on the outer surfaces of the upper leg portion and the lower leg portion of the fastener element which are parallel to each other, and individual weft yarns are added to these warp yarns. A zigzag type slide fastener (Japanese Patent Publication No. 57-58922) in which the fasteners are arranged and woven at the same time to form a covering portion on both sides of the fastener element, and weft threads on both sides of the fastener element are united and run side by side to woven fastener tape
(See Japanese Patent Publication).

As another type of woven slide fastener, two core threads are inserted into a coil-shaped fastener element array made of synthetic resin, and a core string is also inserted to form a fastener tape, and at the same time, The fastener element leg part and one core thread are woven, the fixing weft thread is run from the ground weft thread located outside the other core cord to the other core thread, and the fixing warp thread is arranged between them to hold the fastener element. Woven slide fastener in which the texture is formed and the other fastener element leg is woven (Japanese Patent Publication No. 59-
No. 46162) is known.

The above-described first known slide fastener is a fastener chain in which zigzag fastener elements are symmetrically attached from above and below in a form sandwiching a fastener tape. A so-called concealment type slide fastener that hides the element cannot be finished. In addition, since there is no tightening thread between the warp threads arranged on the outer surfaces of the upper and lower legs, the covering sections formed on the outer surfaces of the fastener elements are not related to each other and are in individual forms. Yes, when removing the fastener element to form the space,
It is unstructured with an opening between both coating portions and an end edge hanging down.
Further, in the fastener tape portion, since the weft yarns in which the upper and lower leg portions of the fastener element are woven are both the same type of weaving yarn, the fastener tape is thickly formed and lacks flexibility.

On the other hand, in the woven slide fastener chain in which the coil-shaped fastener element is woven in the case of the second example, the weft thread in the pressing tissue of the fastener element, that is, the fixing weft thread, is the side of the meshing head of the upper leg of the fastener element. In the above, a structure that bypasses the upper surface of the upper leg portion from the lower side of the core yarn and travels to the lower side of the core yarn again, and the pressing tissue is obtained by the intersection of the core yarn and the upper leg portion of the fastener element. Weaving the upper leg of the fastener element inside, sandwiching the upper leg with the core yarn and the fixing weft, it is a woven slide fastener chain that weaves the fastener element, so when finished as a single slide fastener, The core thread arranged on the upper leg side in the fastener element floats from the pressing tissue, and the core thread hangs naturally at the edge of the fastener tape. Is unsightly Te. Moreover, the core thread that hangs down during use is caught between the left and right fastener elements during the closing operation of the slide fastener, which makes the operation difficult. Therefore, in order to prevent the core yarn from floating, the fastener element remaining in the presser tissue is left as it is to make a slide fastener, but in this form the fastener element remains in the space part and it becomes thicker The quality was not good.

The present invention has been invented in order to solve the above-mentioned problems, and when a slide fastener chain in which a coil-shaped fastener element is woven is finished into a slide fastener, a meshing head portion or a connecting portion of the fastener element is formed. Cut and completely remove the remaining fastener element from the fastener chain to form a space portion, the covering structure of the fastener element, that is, the core string,
The core yarn, the fixing warp, and the fixing weft are all arranged and held in an orderly manner without floating from the fastener tape portion,
The woven slide fasteners and fastener tapes that have a thin space with a thin space have flexibility, and the fastener element is firmly attached, and the attachment portion of the fastener element can be easily curved to the back side. It is an object to provide a woven slide fastener.

[0007]

The fastener chain 1 described above is shown in FIG.
Since the fixing weft yarn 11 is thinner than the ground weft yarn 10 as shown in Fig. 3, the covering structure on the lower side of the two rows of the fastener elements is not dense, and the fastener elements 2 should be formed so that they can be easily curved on the mounting side. By further heat-treating the fastener chain 1, the fixing warp yarns 14 have greater shrinkability than other woven yarns, so that the fastener chain 1 is more likely to bend, and the fastener element 2 is also stronger. It can be fixed to the fastener tape 8. In the fastener chain 1 configured as described above, the fastener element 2 in the section C is completely removed to form the space portion 16 as shown in FIG. 6, and the fastener chain 1 is cut in the middle of the space portion 16. , Slider and upper stopper, lower stopper or separable bottom end stop are attached to complete the slide fastener.

[0023]

The woven slide fastener of the present invention has the above-mentioned structure, and has the following effects.

Two core yarns 4 and 5 are vertically arranged on the side of the meshing head 7 in the two rows of the coil-shaped fastener element, and the connecting portion 6 is provided.
The core cord 3 is inserted through each side, the upper leg 12 is woven by the ground warp 9 and the upper core yarn 4 and the double pick ground weft yarn 10, and the ground weft yarn is inserted between the core cord 3 and the lower core yarn 5. A plurality of fixing warps 14 that are entangled at appropriate positions are arranged in the position 10, and the fixing warps 14 are entangled at the appropriate positions of the lower core yarns 5 and run on the outside of the core cord 3 in a double pick that is thinner than the ground weft yarn 10. Weft for fixing 1
1 and the lower leg portion 13 is woven, and the ground weft yarn 10
Since the fastener tape 8 is woven by running together the fixing weft 11 and the fixing weft 11, the fastener element 2 is extremely firmly attached to one side edge of the fastener tape 8, and all the woven threads at the upper and lower ends of the slide fastener have a stable shape. Therefore, there is no adverse effect that the fastener element 2 is loosened from the end portion, and the space portion 16 has an effect of maintaining an orderly shape.

Moreover, since the fixing weft yarn 11 is thinner than the ground weft yarn 10, the slide fastener can be easily curved to the side where the fastener element 2 is mounted, and when it is used for an article for storing items such as bags and clothes, It is suitable because it does not have the adverse effect that it bends to accommodate stored items and causes chain cracking.
Further, since the fastener tape 8 itself has different thicknesses of the ground weft 10 and the fixing weft 11, and the two wefts are united to form the fastener tape 8, the fastener element 2 is fixed in an extremely stable state. In addition, there is an effect that a flexible slide fastener can be obtained without thickening the fastener tape 8.

Further, the fixing weft 11 runs between the connecting portion 6 of the fastener element 2 and the core string 3, and the weft 1
The tip of 1 is a fastener element 2 via a lower core thread 5.
The lower leg 13 of the fastener element 2 and the lower core yarn 5 or the warp 14 for fixing the side edge between the adjacent fastener elements 2 and the lower leg 13 of the fastener element 2.
Since the outer surface of the fastener is covered with a plurality of fixing warp yarns 14, the connecting portion 6 of the fastener element 2 is completely exposed from the surface of the fastener tape 8, the guideability of the slider is excellent, and the lower leg portion 13 of the fastener element 2 is provided.
Since the outer surface of the slider is covered with the fixing warp yarns 14 arranged in the longitudinal direction, the slider can be slid smoothly.

Further, since the fixing weft 11 is about half the thickness of the ground weft 10, it has the effect of reliably maintaining the flexibility of the fastener tape 8 and the tendency of the fastener chain 1 to bend easily, and also for fixing. The warp 14 is the weft 11 for fixing.
Since a yarn having a heat shrinkage larger than that of the ground weft yarn 10 is used, the fastener element 2 is firmly fixed, and the weave design of the front and back surfaces in the space portion 16 is tightened to open the side edges. The effect is extremely remarkable, such as obtaining a slide fastener with good appearance.
