Abstract

PROBLEM TO BE SOLVED: To solve problems that when a double coated adhesive film is used in a metallic endless belt, waterdrops still remain in a gap of a joint part between an initial end and a terminal end of the double coated adhesive films despite wiping-off of the joint part after washing the double coated adhesive film and wiping out water, and cloth is stained due to the left waterdrops when the cloth is stack again on the double coated adhesive film, and that when the terminal end of the adhesive film is stack to overlap with the initial end of the adhesive film so as to leave no gap between both ends, an upper part of the overlapped ends is worn away heavily and an adhesive is apt to peel off the base material so that a new adhesive film should be completely re-stack. SOLUTION: In a cloth conveying device conveying cloth by the endless metallic conveying belt and the double-face adhesive film, the adhesive film for the joint is adhered to a joint formed between ends of the double-face adhesive film.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the fabric transport apparatus of the present invention and the textile printing apparatus having the fabric transport apparatus, a double-sided pressure-sensitive adhesive film is attached to a transport belt made of an endless metal. Because the adhesive film for the seam is stuck on the top, the step at the seam at the end of the double-sided adhesive film is eliminated or reduced again, so after washing the double-sided adhesive film and wiping off the moisture, The problem that water drops do not remain in the gaps between the adhesive films and the cloth is stained by the water drops is solved.

The use of the adhesive film for seam is also effective against the problem that the upper part of the film (the adhesive on the fabric side) when the films are stacked and adhered to each other is easily abraded and easily peeled off. Since it is possible to replace only the film, it is not necessary to replace the entire double-sided adhesive film, and the replacement operation is facilitated, and the operability is further improved.

Further, by making the fabric side pressure-sensitive adhesive of the seam pressure-sensitive adhesive film the same material and having the same characteristic values (adhesive strength, holding power, tacking force, etc.) as the fabric side pressure-sensitive adhesive of the double-sided pressure-sensitive adhesive film, the double-sided pressure-sensitive adhesive with the fabric is obtained. The state of adhesion to the film and the state of adhesion between the cloth and the adhesive film for seam become the same, and there is no step at the seam at the end of the double-sided adhesive film, so that there is no unevenness in the pattern at the time of printing.

Further, the adhesive film for seam includes:
By using a film with a small thickness, the step when the adhesive film for seam is stuck on the double-sided adhesive film is small, the difference in the gap between the head of the ink jet printing device and the fabric is small, and the No unevenness occurs. In addition, since the step portion is small, no water droplet remains on the step portion, and the cloth is not stained by the water droplet.

There is no unevenness in the picture at the time. Further, since the step portion is small, no water droplet remains on the step portion, and the cloth 1 is not stained by the water droplet.

(Others) Next, the entire process of ink-jet textile printing will be described. After the ink-jet printing step using the above-described ink-jet printing apparatus, the fabric is dried (including natural drying). Subsequently, a step of diffusing the dye on the fabric fiber and reacting and fixing the dye to the fiber is performed. By this step, it is possible to obtain sufficient color-forming properties and fastness due to fixation of the dye.

This diffusion and reactive fixing step may be a conventionally known method, for example, a steaming method. In addition,
In this case, the fabric may be subjected to an alkali treatment before the printing step.

Thereafter, in a post-treatment step, unreacted dye and substances used in the pre-treatment are removed.
Finally, the record is completed through an orderly finishing process such as defect correction and ironing.

In particular, as a fabric for ink-jet printing, (1) the ink can be colored to a sufficient concentration;
(2) high ink dyeing rate; (3) quick drying of the ink on the fabric; (4) less occurrence of irregular ink bleeding on the fabric; And high performance such as excellent transportability. In order to satisfy these required performances, in the present invention, the fabric can be subjected to a pretreatment beforehand, if necessary.

Is preferred. Such a fixing step may be performed by a conventionally known method, for example, a steaming method, an HT steaming method, a thermofix method,
When a fabric which has been previously alkali-treated is not used, an alkali pad steam method, an alkali blotch steam method, an alkali shock method, an alkali cold fix method and the like can be mentioned. The fixing step may or may not include a reaction process depending on the dye. As an example of the latter, there is a method in which fibers are impregnated and do not physically separate.

And the fabric includes all woven fabrics, nonwoven fabrics and other fabrics, regardless of the material, weave or knitting.

The method for incorporating the above substances and the like into the fabric in the pretreatment is not particularly limited, and examples thereof include a commonly used dipping method, padding method, coating method and spraying method.

Furthermore, since the printing ink applied to the ink-jet printing cloth is merely adhered when applied to the cloth, it is necessary to carry out a fixing step of the dye or the like in the ink onto the fiber. Is preferred. Such a fixing step may be performed by a conventionally known method, for example, a steaming method, an HT steaming method, a thermofix method,
When a fabric which has been previously alkali-treated is not used, an alkali pad steam method, an alkali blotch steam method, an alkali shock method, an alkali cold fix method and the like can be mentioned. The fixing step may or may not include a reaction process depending on the dye. As an example of the latter, there is a method in which fibers are impregnated and do not physically separate. As the ink, any suitable ink can be used as long as it has a required pigment, and the ink is not limited to a dye and may include a pigment.

Further, the removal of unreacted dye and the substances used for the pretreatment can be carried out by washing after the above-mentioned reaction fixing step according to a conventionally known method. In addition, it is preferable to use a conventional fixing process in combination with this cleaning.

In the textile printing apparatus according to the tenth aspect of the present invention, since the ink jet print head has an electrothermal converter for generating thermal energy for discharging ink, the ink is discharged using thermal energy. As a result, high density and high definition of the print can be achieved, and the finish is beautiful.

In the textile printing apparatus according to the eleventh aspect of the present invention, the ink jet print head uses thermal energy to generate air bubbles in the ink and discharges the ink by the generation of the air bubbles. I can go and print beautiful and clear.
