Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karami woven fabric having a pattern pattern having a three-dimensional effect by combining a jacquard weaving technique, a kalami weaving technique and an ink jet dyeing technique, and a manufacturing method thereof. Here, the pattern having a three-dimensional effect means a pattern having a weaving structure, a print pattern matching the pattern, or a pattern having a shadow portion matching the print pattern.

2. Description of the Related Art As a general method of expressing a pattern on the surface of a woven fabric by a weaving structure, a special machine (tappet, dobby or jacquard loom) is used to mechanically operate an opening device to form a complicated pattern ( Hereinafter, the generic name "jacquard weave" is known. Further, the Karami woven fabric is one in which warp threads and weft threads are entangled with a Karami heddle to prevent misalignment (misalignment) between the entangled portions of the two. Furthermore, the inkjet dyeing machine is an application of the printing technology of an ink jet printer to the printing technology. Based on the information of the original figure registered in the computer, ink drops are jetted onto the cloth to print various kinds of prints on the surface of the cloth. This is a technique for forming patterns. It is possible to form a pattern by the woven structure in the full width of the fabric by jacquard weaving in ordinary fabrics except for kalami fabric, but in the case of kalami fabric, when a pattern is formed in the full width of the fabric, The region where the pattern could be formed by performing jacquard weaving was a part of the width of the fabric because a dark line-like weaving defect occurred in the central part of the fabric.

Ordinary woven fabrics manufactured by the jacquard weave are dyed as a product when the pattern of the weaving structure is used as it is, and when the pattern formed by the weaving structure is used as a ground pattern, a screen is used. A print pattern unrelated to the ground pattern was formed on the surface of the fabric using a printing machine. Since the pattern of the jacquard woven fabric is formed by the woven structure, the jacquard woven fabric has unevenness when touched with a hand and has a high-class feeling.

On the other hand, the Karami fabric has a weave density of 14 /
It has an inch size, low warp and weft density, and has the same breathability as gauze and gauze. It has a high-class feeling, and usually forms a print pattern by plain dyeing or printing, and then scarves, textiles, parasols, tapestry. It is used for such purposes. An example of Karami fabric is Patent 3
No. 235377.

The ink jet printing technique is suitable for production of a large number of small quantities, has a merit that the amount of ink used is small and the environmental load is small.

[0006]

However, in the case of performing jacquard weaving on a kalami woven fabric to form a pattern having a weaving structure, there is a drawback in that high-speed operation cannot be performed, so that the production amount per hour is small and the manufacturing cost is high. In addition, the Karami woven fabric has the disadvantages that when it is printed with a screen printing machine, the color paste is excessively adhered to cause color stains, and the color paste is wasted.

On the other hand, in ink-jet dyeing, the production cost increases when the amount of ink deposited is increased, and when the amount of deposited ink is reduced, the print pattern formed on the surface of the woven fabric exposes the non-dyed part when the woven fabric is folded ( Peel white eyes),
There is no depth of color, and there is the problem of giving a sense of quality. .

SUMMARY OF THE INVENTION The present invention has an object to solve the above-mentioned problems, and provides a Karami woven fabric which is jacquard-woven and has a pattern of a weaving structure over the entire width of the fabric. It is an object of the present invention to provide a Karami woven fabric having a smooth and three-dimensional appearance and a method for producing the same.

[0009]

A Karami fabric according to a first aspect of the present invention is characterized in that a jacquard weave is performed to form a pattern having a weave structure over the entire width of the fabric.

The Karami fabric according to claim 2 is characterized in that, in the Karami fabric according to claim 1, a print pattern adapted to the pattern is formed on all or part of the pattern by an inkjet dyeing machine. is there.

According to a third aspect of the present invention, a kalami fabric is used which is jacquard-woven to form a pattern having a weave structure.
Register the drawing information of the same shape as the pattern by the jacquard weave structure in the computer of the inkjet dyeing machine,
Based on the drawing information, ink droplets are ejected on the paper fixed to the inkjet dyeing machine to form the original drawing, and the Karami fabric is fixed on the original drawing by aligning the positions of the patterns with the registered original drawing information. Based on the above, a computer operates an inkjet dyeing machine to eject ink droplets to form a print pattern suitable for the pattern of the Karami fabric.

According to a fourth aspect of the present invention, in the method according to the third aspect, the print pattern includes a shadow portion adapted to the print pattern.

[0013]

According to the present invention, the kalami woven fabric according to claim 1 or 2 is formed by jacquard weaving to form a pattern having a woven structure over the entire width of the fabric, and if necessary, a print pattern adapted to the pattern of the kalami woven fabric is formed by ink jet dyeing. Can be prevented from being excessively attached, and a print pattern suitable for a pattern can be provided at low cost. Therefore,
It is possible to obtain high-quality Karami fabric that has a three-dimensional effect when viewed from a distance or near.

In the method for producing a kalami fabric according to claim 3 or 4, since the pattern of the original drawing set on the ink jet dyeing machine and the pattern of the kalami textile are fixed so as to match with each other, the computer can use the registered original drawing information. By ejecting ink droplets, it is possible to easily form a print pattern that matches the pattern. Moreover, the amount of ink used is small, and the ink can be used effectively.

[0015]

1 to 4 show an embodiment of the present invention. FIG. 1 is a Karami fabric used for neckerchief, and FIGS. 2 and 3 are enlarged views of a portion A of FIG. A pattern pattern 10 having a three-dimensional effect is formed in the center of the Karami fabric 1. The pattern 10 is an “egg” pattern having a crack pattern 9, is formed of a jacquard weave design, and a print pattern that matches the pattern 10 is printed by an inkjet printer. A shadow portion 4 is formed on the lower right of the print pattern.

The weave structure of the Karami woven fabric of FIG. 2 is obtained by twisting polyester filament yarn of 70 decitex / 3 filler at 800 T / M, and wrapping it in three braids and a warp yarn group from above and below. It is composed of a weft thread group consisting of three weft threads 3 sandwiched. The weft yarn 3 is a polyester filament yarn of 70 decitex / 3 filler kneaded with a metal-containing special deodorant for ceramics, twisted at 800 T / M (Kuraray, registered trademark "Shine Up"). Such a weft thread exhibits a deodorizing effect by a chemical adsorption reaction and a photocatalytic reaction.

In order to form the egg handle 10 of FIG. 1 on the Karami woven fabric by the weaving structure, jacquard weaving is performed by operating an opening device (not shown). The weft density (weave design) may be changed by widening the gap and inserting the bundled weft yarn therein, and if necessary, by widening the space between the three weft yarns 3 for the portion C in FIG. Next, when the crack pattern 9 is formed, a part of the weft yarn may be sequentially floated to form a zigzag diagram.

In the above weave design, the kalami design is such that at the interlaced portion 8 of the warp yarn 2 and the weft yarn 3, the warp yarns pass alternately above and below the weft yarns, and the warp yarns pass alternately above and below the weft yarns, Since the weft yarn is held between the upper warp yarn and the lower warp yarn, misalignment is prevented.

FIG. 3 shows a weave design of Karami weave different from that of FIG. 2, in which two ground warp yarns 2a and one entangled warp yarn 2b are formed by the left-right entanglement pull-in while facing each other. FIG. 3 is a view showing, from the front side of the woven fabric, what has passed through the three weft threads 3 while the entangled warp threads 2b are entangled once.
Since the entangled warp yarns 2b are entangled one by one in a face-to-face relationship, the entanglement of the weft yarns becomes large, and the effect of suppressing misalignment is great.

FIG. 4 schematically shows a method of manufacturing the print pattern shown in FIG. The blank paper 18 is fixed in the traveling range of the print head 5 of the inkjet dyeing machine, and the pattern is once printed out on the blank paper 18 based on the registration information to obtain the original drawing 6. The Karami fabric 1 is placed on the original drawing, and the handles 10 and 7 of both are aligned and fixed, and then the motor 13 of the endless belt 12 is set by the computer 11.
And the motor 15 of the screw can 14 is driven by intermittent motion or constant speed motion to move the printer head 5 vertically and horizontally to eject ink droplets based on the registered pattern information to form the print pattern 10 on the Karami fabric 1. I will do it. Especially in the area where a shadow is required to give the pattern a three-dimensional effect, hue, saturation,
It is preferable to eject ink droplets so that the shade 4 is formed by gradually reducing the lightness.

[0021]

According to the present invention, it is possible to obtain a Karami woven fabric having a pattern pattern formed over the entire width of the fabric. By dyeing this, it can be used in the field of interiors such as clothes with a watermark pattern and partitions. Furthermore, if you give a print pattern that matches the pattern of the weave structure,
It is possible to obtain a kalami woven fabric having a pattern pattern that gives a three-dimensional effect when viewed from a distance or near.

According to the method of the present invention, a print pattern can be easily formed in conformity with the pattern of the Karami fabric, and the consumption of expensive ink drops can be reduced, and at the same time,
The printing speed can be increased and the manufacturing cost can be reduced. In addition, it is possible to prevent stains on the Karami fabric due to excessive ink drops as much as possible.
