Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a patterned fabric and its III! The present invention relates to an I-making method, and specifically relates to fabrics having irregular patterns in the width direction and length direction, which can be used for, for example, saris, which are Indian national costumes.

[Conventional technology]

Fabrics with irregular patterns in the width and length directions can be produced by using a multi-shuttle loom on both sides and attaching a jacquard, or by removing unnecessary wefts after making the dragon. There is a way to betray me.

[Problem that the invention seeks to solve]

When using the above-mentioned multi-shuttle loom, the production speed is slow, the efficiency is very low, it takes a lot of work due to betrayal, and the cut threads are wasted, making it uneconomical and high cost. There is a closed head.

It is an object of the present invention to improve such drawbacks and to efficiently produce patterned fabrics having irregular patterns in the width direction and length direction using a jet type V& machine at a low cost.

[Means for solving problems]

The first invention is a woven fabric woven by a weft jetting method, in which the woven fabric has a structure in which the weft densities are partially different, and a pattern is formed at the boundary between the densities.

The second invention is a weft injection type loom (where a plurality of wefts are simultaneously injected into the same opening, and at least one of the plurality of wefts to be injected is normally e-woven fabric). The entire width of the fabric is inserted into the weft, and the other weft yarns are inserted into the inside of the woven fabric depending on the length and shortness, and the weft density of the fabric is partially different.
A pattern is formed at the boundary between the densities.

[Function and Examples]

The operation of the present invention will be explained based on embodiments shown in the drawings.

Figure 7 shows the plane 1 of the patterned fabric according to the present invention, where (1) is a patterned area with a high weft density, which is organized by warp (3) and a plurality of wefts (ga) (4'b). .

In addition, (2) is a pattern part with a small weft density, and the warp (3)
) and weft threads (41)).

Therefore, the boundary (4) between (1) and (2) with different weft density
A pattern will be formed.

That is, the patterned fabric according to the present invention has an irregular @-like pattern due to substantially different weft densities in the width direction and length direction of the fabric.

There are no particular restrictions on the types of weft yarns (ga) Cgb) and warp yarns +3), and various synthetic fibers, their bulky processed yarns, etc. can be used, and multiple weft yarns Tga+ (4'b) may be of the same or different types (And the number of weft threads is not limited to two.

The weft (4) and the warp (3) can be combined in 10 combinations depending on the purpose. For example, the warp (3) is a polyester yarn, the weft (4) is a metallic yarn, the warp (
For 3), a basic dye dyeable polyester yarn can be used, and for the weft yarn (4), a normal polyester yarn can be used.

Next, a method for manufacturing the patterned fabric of the present invention will be described.

Fig. 2 shows a schematic diagram of the process for producing the special patterned fabric of the present invention using a water jet loom.
'a) passes through guide 0, yarn breakage stopper n'J), and guide 11304, and is measured to an appropriate length within the fabric pile using length measuring roller OL, and that length is stored in pool vibe aQ. .

After the beating operation is completed, it passes through the guide α force and is held by gripper 4, and when gripper 0 barrel opens, nozzle 09
It is injected into the opening ω of the twisted warp (3).

On the other hand, the weft yarn (4"b) (weft yarn for ground yarn) similarly passes through the guide t11%@, - and is measured in the fabric by the measuring roller (to), and
For example, the weft (4'a) and the warp (3) are injected from the nozzle 4 into the opening η of the warp (3).

In this case, the ground weft (4'b) reaches the opposite side of the nozzle (19, (support)), but one weft (4'l) is ejected by an arbitrary length measured by the measuring roller O. Because of this, the nozzle stops halfway through the fabric and does not reach the opposite side of the nozzle (+9, 4).

For this reason, the weft yarn densities differ in the width direction and the length direction of the fabric, resulting in the formation of irregular patterns.

The injection length of the weft ['Ja'] into the warp opening (4) is:
For example, this can be done by controlling the rotation speed of the length measuring roller QF9, and thereby the pattern portion f1) (2)
It becomes possible to freely form patterns.

The number of weft yarns (4) is not limited to the two types in the embodiment, and a plurality of three or more types can be used.

In this fJK case, if a plurality of wefts (4) are jetted simultaneously, a single nozzle can jet the wefts (4).

It can also be used in the same way in an air jet room.

〔effect〕

The present invention makes it possible to obtain a patterned fabric with an irregular pattern by varying the weft density in the width direction and length direction of the fabric, and to efficiently produce it at high speed without wasting the weft. is possible.

Such patterned fabrics are useful not only for sarees, the Indian national costume, but also for various types of clothing.
