Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a multi-warp woven fabric, a weaving method for the same, a loom capable of weaving the same, and a heddle for weaving the multi-warp woven fabric. In more detail, we are developing a new type of fabric that can produce various changes in the thickness, properties, color, texture, etc. of the fabric by skillfully overlapping warp threads in multiple layers, and The present invention relates to a method for rationally weaving such fabrics, a loom, and a heddle used for weaving such fabrics.

C. Prior Art and Technical Problems to be Solved] A textile fabric woven with two or more warps and/or wefts is called a layered fabric (cotnbination weave).
), and three types are conventionally known: single layer structure, double layer structure, and multilayer structure. However, these layered fabrics are similar to dobby (dobbyNH machine) and jacquard (jacqud) fabrics.
ard) Since weaving cannot be done without using a special loom such as a loom, the cost is high due to the cost of designing pattern cards, etc., and the production efficiency is low.The current situation in the weaving industry is that speeding up is required. It could not be said that it could adequately cope with the situation.

The present invention was made in view of the fact that the conventional process of +aA weaving of layered fabrics and the looms used to weave the same had problems in terms of production efficiency and production cost, as described above. It is possible to weave with ordinary looms (including shuttle looms, rapier looms, and jet looms) without using special looms such as Dobby Ia machines and Jacquard looms that use equipment, and it is possible to weave with the above-mentioned layered looms. The technical problem is to provide a new type of multi-warp woven fabric that responds to the above-mentioned problems.

Another technical object of the present invention is to provide a new method capable of efficiently weaving such a multi-warp fabric.

Another technical object of the present invention is to provide an Ia machine with a new function capable of weaving not only ordinary woven fabrics but also the aforementioned multi-warp woven fabrics.

Furthermore, another technical object of the present invention is to provide a heddle that is equipped with a plurality of mails into which a plurality of warp threads can be inserted, and which can branch out the plurality of warp threads in a superposed state.

[Means adopted to solve the problem]

The means adopted by the present inventor to solve the above technical problem are as follows.

First, the present invention is based on the technical premise of a conventionally well-known woven fabric that is organized by intersecting warp and weft threads, and arranges a plurality of warp threads in each row in a stacked manner to form warp weaving lines. By adopting a method of cross-inserting the weft yarns by using a loom, it was possible to create a multi-warp woven fabric that is almost the same as the layered fabric woven using conventional dobby or jacquard looms. A warp overlapping shedding method in which the warp threads are branched vertically by healds, and when inserting the weft threads into the opened sheds, a plurality of warps in each row from the warp beam are stacked at the heddle and branched all at once. By using one method, we were able to realize a method that can weave multi-warp fabrics using a normal heddle control mechanism without using special heddle control mechanisms such as dobby or jacquard, and furthermore, A heald device that vertically branches the warp threads sent out from the warp beam in an aligned manner; a weft insertion device that inserts the weft threads into the opened shed; a beating device that beats the inserted weft threads against the fabric; In a conventionally well-known loom equipped with a cloth winding beam that winds up the fabric that is sequentially woven in the weaving front, it is possible to produce multi-warp fabrics by providing a plurality of means called warp insertion mails in each of the healds in the heddle device. ! They created a loom that could weave.

Example C) The present invention will be described in more detail below based on examples shown in the attached concave surface. In addition, FIG. 1 is a principle diagram for conceptually explaining the method for weaving the multi-warp fabric of the present invention and a loom for weaving it, and FIG. 2 is a sectional view showing an embodiment of the multi-warp fabric of the present invention. Fig. 3 is a partially omitted front view showing an embodiment of a flat type heddle used for weaving the multi-woven fabric of the present invention, and Fig. 4 shows an example of the wire-type heddle used for weaving the multi-woven fabric of the present invention. It is a partially omitted front view shown.

First, referring to FIG. 1, what is designated by reference numeral 1 is a pair of heald devices installed front and rear facing each other, each of which has two warp insertion mails 12 bows 2. are arranged in a vertical line, and the front and rear heddle devices are moved up and down in opposite directions by a tappet mechanism (not shown) that is linked to the rotational speed of the main shaft of the loom. is configured so that it is given.

As shown in the figure, the warp threads W-W fed out in alignment from the warp beam B are inserted in each of the upper and lower warp thread insertion mails 12, 12 in a predetermined order in each of the heald devices 1, 1. Two warps are arranged in a stacked state, and by interlocking with the heald device 1.l, the warp threads W-W... of each row are branch-opened in a stacked state.

The reference numeral 2 indicates a weft insertion device, and the shuttle 2 is illustrated in the loom of this embodiment. This shuttle 2 flies reciprocatingly through sheds of warp yarns W-W, which are branch-opened in the stacked state by a picker (not shown), and wefts Y into the sheds.
Insert it.

Next, what is indicated by the code 3 is the beating device,
Each time the weft thread insertion device 2 inserts the weft thread Y into the pillow, it beats and pushes it in the direction of the fabric front F to form a woven fabric C.

This beating device also operates in conjunction with the rotation of the main shaft of the loom (not shown). The woven fabric C thus woven is sequentially wound around the cloth winding beam T, and these structures are well known in the art.

Next, a description will be given of FIG. 2 showing a multi-warp woven fabric (in this example, a double-warp woven fabric) produced by the above-described example loom. A polyester thread W1 and a cotton thread W2 are used, and they are arranged in a stacked manner such that the polyester thread W1 is exposed on the upper surface of the front side of the fabric, and the cotton thread W1 is exposed on the lower surface of the back side of the fabric. has been done. Therefore, since the cotton yarn 6 is exposed on the back side of the woven fabric of this example, it has good moisture absorption and sweat absorption properties, and since the polyester yarn 1 is exposed on the front side, it has a smooth feel and is suitable for printing, etc. It has the characteristic that it is easy to apply patterns. In addition, the code|symbol Y in the same figure shows a weft.

Although the present invention has been explained above using examples, the present invention should not be interpreted as being limited to the above-mentioned examples.
It goes without saying that various design changes are possible within the scope of the claims.For example, in the multi-warp woven fabric of the above embodiment, the warps -1 and -6 are arranged in two layers. However, it is also possible to stack the three warp threads in a gate-shaped arrangement, and the number of stacked warp threads may be as many as physically possible, and the color of the warp threads selected
Various thread quality and thickness can be used as desired.

Further, the present invention can be used as a loom for weaving multi-warp fabrics, not only the shuttle am of the above embodiment, but also fluid injection looms such as air jet looms and water jet looms, fragmentary weaving machines such as rough rapier looms, etc. Applicable to most looms using heddle devices.

Furthermore, the heddle of the loom used when weaving the multi-warp woven fabric of the present invention is also a flat type heald 11 having a plurality of warp insertion mails 12, 12 as shown in FIG.
Various types of healds, such as a wire type heald 11 having a plurality of warp insertion mails 12, 12 as shown in the figure, can be adopted.

[Effects of the present invention] As is clear from the above description, in the woven fabric of the present invention, each row of warp yarns constituting warp weave lines is stacked one on top of the other. As long as you select the color, quality, thickness, gloss, etc. of the warp threads exposed on the top surface of the fabric and the warp threads exposed on the back side of the fabric, you can change the color, texture, design, etc. of the front and back sides of the fabric itself. can be varied in a wide variety of ways, making it possible to increase the variety of textile products.

Furthermore, according to the method of the present invention, there is no need for the complicated design of pattern cards as in conventional dobby textile machines and jacquard looms, and conventional general-purpose shuttle looms, fluid injection looms, and rapier looms with improved heald parts can be used. It is possible to easily and efficiently weave a multi-warp fabric by a normal helding operation.

Furthermore, in the machine m of the present invention, the heddle constituting the heddle device is equipped with a plurality of warp thread insertion mails, so when a multi-warp woven fabric is desired, the warp threads are inserted into each of the mails for weaving, and the other When a normal woven fabric is required, it is possible to weave by inserting the warp threads through only one mail, so it can be said to be extremely advantageous from a practical point of view.
