Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a machine for patterning textiles for tatami mats by printing. In the case of a tatami mat, the pattern obtained by printing has a degree of freedom that conventional products do not have, and has an advantage of giving a high-grade feeling to consumers at a low cost.

Since the tatami mat manufactured by the method of the present invention can express concrete figures, it can be printed by printing animal and plant patterns, animated characters, trademarks, characters, etc. for tatami mats exclusively for children's rooms and fans for specific products. It can be used for tatami mats and can add high added value.

The tatami mat produced by the method of the present invention can be printed with a huge pattern or a fine pattern that cannot be expressed by a jacquard weave, and can be used as a hem of a flower or a cushion of a straw mat. A high added value can be given by combining patterns that match with.

2. Description of the Related Art Traditionally, tatami mats are made from narrow width dyed fabric. The one woven with one type of colored yarn called a plain fabric is mainly woven with a plain weave design. This type of tatami rim gives a tatami-like image to the tatami. In addition, since it is easy to manufacture, production in low-wage countries is extremely advantageous, and there is a problem that the profit margin of domestic manufacturers is gradually decreasing.

The main product of conventional tatami mats is made from narrow width dyed jacquard fabric. A characteristic of jacquard fabrics is that many types of patterns can be easily woven, but the floating and sinking threads that make up the pattern overlap to make the cloth thicker. There is a problem that it is easy to get caught in a machine or the like, the needle passage tends to be poor, and the bending hardness locally fluctuates drastically, so it is difficult to follow the ridgeline of the edge of the tatami mat and a high level of skill is required. Such a defect is not so remarkable in the case of sewing by hand-sewn, but it is remarkable in using a sewing machine. In recent years, there is a tendency to dislike the expensive sewing of tatami mats,
The difficulty of using sewing machines has been recognized as a serious defect in the tatami mat.

The sewing characteristics of the tatami mat with the yarn-dyed jacquard fabric can be solved by using a thin thread for the weaving thread, but there is a problem that if the thread is thin, the abrasion resistance is significantly reduced, and Since it was originally made of hemp fabric, consumers had the preconceived idea that hard fabric was good, and tended to hate thin fabric sensuously from such a preference. However, there is a problem that it cannot sell.

Printing of narrow width fabrics has not been performed so far, but it cannot be said that the technique is specially different from ordinary fabrics. However, when the narrow fabric was actually printed and a practical test was conducted as a tatami mat, it was found that the tatami mat was very easily soiled because of its high ability to adsorb dust. Moreover, it has been found that there is a problem that no marked improvement is observed even when the fabric is subjected to antifouling treatment or antistatic treatment.

[0008]

DISCLOSURE OF THE INVENTION The present invention has the problem that the conventional tatami mat having a plain weave design has a low added value and does not have international competitiveness. The aim is to solve the inferior problem of. It is another object of the present invention to solve the problem that the conventional textile printed is extremely susceptible to stain when evaluated as a tatami mat.

[0009]

According to the present invention, a narrow woven fabric or an ordinary woven fabric slit into the width of a tatami edge is used, and after removing the fluff on the surface, a pattern is formed with a dye or pigment containing glue or the like. Printing and fixing,
This is a method of printing tatami mats. When ordinary fabrics, especially dyed fabrics, are used as tatami mats, cotton dust and the like existing in the room are adsorbed to give a dirty appearance in a short time. The degree of stains is more intense with darker dyes. It was conventionally thought that the pollution due to the adsorption of dust was caused by static electricity, but in reality, even if antistatic processing or various antifouling processing was applied, no effect was seen and commercialization was difficult. Had been judged.

As a result of various studies, it was found that the cause of the contamination was that the dust was entangled with the fluff existing on the surface of the woven fabric to promote the contamination, and the present invention was reached. In the present invention, the method for removing the fluff that the fabric has on the surface is a method of scraping off the fluff by rubbing the surface with sandpaper or a brush, or a method of applying a sizing agent while rubbing, and a method of burning off the fluff with a flame or a chemical agent. Are used. The step of removing the fluff is preferably performed after weaving the woven fabric from the viewpoint of cost, but it can be performed at the stage of the yarn before weaving and is excellent in quality.

It is not possible to eliminate virtually all the fluff of a spun yarn fabric. However, the fluff that is entangled in the cotton dust is only quite long, and the problem is that the fluff sticks to the surface of the fabric. Since the tatami mat is not subjected to friction such as rubbing, the pattern reversal phenomenon on the front and back sides due to the movement of the weaving yarn that frequently occurs in the woolen fabric does not occur. Therefore, fluff can be removed only on the front side.

As a preferred apparatus for carrying out the method of the present invention, as shown in FIG. 1, after the dough unwinding device having a narrow tape-shaped raw cloth bobbin 1 wound in a tubular shape, A fluff removing device such as a roller 2 for removing the fluff of the cloth is provided, and a printing device using the engraving roll 3 for textile printing in which a pattern is engraved is further provided to print a dye or pigment containing glue or the like, and hot air drying is performed. A device which is heated and fixed by a device such as a machine 6 is lifted. By using this apparatus, the tatami mat fabric can be continuously and efficiently printed.

As a more preferable apparatus for carrying out the method of the present invention, the unwinding apparatus performs position control so that the center line of the tape-like material and the center line of the pattern engraved on the roll coincide with each other. It is possible. Here, the center line of the pattern is not a center of symmetry of the pattern, but a line determined so that the pattern on the tatami edge comes to the most preferable position when sewn on the tatami. For this line, the center line of the pattern was always selected so that the narrow woven fabric for the edge does not have directionality in the conventional jacquard tatami edge, but the center line of the sewn tatami edge is It is customary to differ from the center line of the fabric, and it is not necessary to follow this convention when patterning by printing. If the pattern is formed according to the position to be sewn on the tatami mat, it is possible to reduce the cost of patterning unnecessary parts and reduce the pattern matching mistakes when sewing.

[0014]

According to the method of the present invention, when the woven fabric is used as a tatami mat, the problem of poor machine-sewing property and the problem of adsorbing a large amount of cotton dust, which are disadvantages, are printed on the plain weave design. This improves the smoothness of the cloth, improves the uniformity of the bending hardness and improves the sewability, and prevents the fluff from becoming entangled by removing the fluff in the process before printing. It is something that can be solved.

EXAMPLES Next, the present invention will be described in detail and specifically with reference to Examples.

Example 1 A pattern is printed using a narrow fabric having a fabric width of about 7.5 cm, in which 246 16 count cotton yarns are used as warp yarns and 16 count cotton yarns are driven in as a weft yarn at a density of 75 yarns per 25 mm. I went. The narrow woven fabric was continuously unwound at a speed of 5 m / min, a polyvinyl alcohol aqueous solution (PVA124 made by Kuraray dissolved in a concentration of 12%) was applied to one side of the woven fabric, and then the surface speed was made by using a rotating brush made by palm. 200m
Suffering was performed by rubbing at 1 / min. Immediately after rubbing, it was dried at 120 ° C. for 7 minutes with a hot air drier, and a pattern was continuously printed with a gravure printing machine and heated to fix. A printing ink in which a pigment was dispersed in a polyurethane resin was used.

Practical evaluation was carried out using this narrow fabric as a tatami mat. When the lightfastness of the printed pattern was measured according to that of an ordinary dyed product, it was judged to be 6 grade or higher. Also, the flat surface wear was extremely good. In the sewn-on test on the tatami mat, the sewability was far better than that of the conventional jacquard fabric. As a result of practical tests, the adsorption of cotton dust was slightly better than that of the conventional cotton-dyed fabric and far better than that of the cotton-dyed fabric.

Example 2 Instead of the narrow fabric of Example 1, 3 pieces of quilled cotton were used.
The same printing process as in Example 1 was performed using a narrow width fabric in which No. 0 double yarn was used as warp and weft, without performing the fluff binding process on the fabric. The robustness of the printed pattern and antifouling property as tatami edges are
It was good as in Example 1.

Example 3 Instead of the narrow woven fabric of Example 1, a narrow woven fabric was woven by using cotton 16th count yarn, which was fluffed at the yarn stage, as warp and weft, and fluffing was performed on the woven fabric. When the same printing process as in Example 1 was performed without performing the above, an excellent tatami edge as in Example 1 was obtained.

Comparative Example 1 In Example 1, printing processing was carried out while omitting the fluff binding processing. When the obtained narrow woven fabric was evaluated as a tatami mat, the color uniformity and the fastness of the pattern were very good, but the stain resistance as the tatami mat was inferior to that of the conventional dyed fabric.

[0021]
