Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an economical double-sided transfer printing fabric having no show-through, excellent color developability, texture and various fastnesses, and a low environmental load, and a method for producing the same. And suitable for bedding material.

2. Description of the Related Art Conventionally, when a color pattern is applied to both sides of a fiber cloth by using a sizing agent such as a screen or a rotary,
A two-step process is performed in which one side is subjected to printing, steaming, washing, and drying steps, and then the other side is subjected to printing, steaming, washing, and drying steps again. Further, conventionally, although there is a cloth in which a color pattern is transfer-printed, there is no cloth in which double-sided transfer printing is performed, and further, there is no cloth in which both surfaces are simultaneously transfer-printed.

[0003]

For thick fabrics, there is a method of printing on both sides at the same time. However, problems such as bleeding of the color paste on the opposite side of the printing surface are likely to occur. Also, in the case of printing with ordinary screens, rotary, etc., it is necessary to carry out a two-step process to give a color pattern on both sides, and further it is necessary to wash with a large amount of water after printing. And the manufacturing cost are high.

In the case of ordinary printing, the number of coloring materials used is limited by the machine base. In the case of transfer printing, if the transfer temperature is too high, not only does the texture become harder, but the transfer pattern shows through. Further, if the transfer printing temperature is too low, sufficient color development cannot be obtained.

Further, when the transfer printing time is short, sufficient color development cannot be obtained as in the case where the transfer temperature is low. Further, when the transfer printing time is too long, not only the texture becomes hard as in the case where the transfer temperature is high, but also the transfer pattern shows through. Further, if the processing time becomes long, there arises a problem that the manufacturing cost becomes high.

Furthermore, 10BG in JIS standard hue
When both sides of the fabric are printed simultaneously with V5 / C8 colors,
If the color difference (ΔE) on both sides is too small, other colors show-through, and if it is too large, sufficient color development cannot be obtained.

The present invention was conceived in view of the current state of the art, and the purpose thereof is to provide economical double-sided transfer printing with no show-through, excellent color developability, texture and various fastnesses, and low environmental load. It is to provide a fabric and a method for manufacturing the same.

Means for Solving the Problems The inventors of the present invention have made extensive studies to achieve the above object, and as a result, have completed the present invention. That is, the present invention is a fabric in which both the front and back sides are simultaneously transfer-printed, and the color difference (ΔE) between both sides when the both sides of the fabric are simultaneously transfer-printed with 10BG V5 / C8 colors of standard hue according to JIS Z-8721. It is a double-sided transfer printing cloth characterized in that

Further, according to the present invention, both front and back surfaces of the fiber cloth are
A method for producing a transfer-printing fabric, comprising simultaneously performing transfer-printing at a heat-treatment temperature of 50 ° C to 250 ° C for 20 seconds to 2 minutes, wherein the fabric has a standard hue of 10BG V5 / C8 according to JIS Z-8721. The method for producing a double-sided transfer printing cloth is characterized in that the color difference (ΔE) between the both surfaces when the both sides are simultaneously transferred and printed.

BEST MODE FOR CARRYING OUT THE INVENTION As the cloth used in the present invention, polyethylene terephthalate fiber, copolymerized polyester fiber, polyamide fiber, acrylic fiber and sheet of woven fabric, knitted fabric, non-woven fabric or the like in which acrylic fiber is singly or compounded Examples thereof include polyester fiber sheet materials.

Since the cloth of the present invention uses transfer printing, not ordinary printing, there is no limitation on the number of coloring materials, and complicated colored patterns can be easily produced. Examples of dyes used for transfer printing in the present invention include disperse dyes, cationic dyes, and acid dyes, with disperse dyes being preferred.

According to the conventional method, when the fabric is printed on both sides, 2
Since the step processing was required and a large amount of water was used, a great load was placed on the water quality. In addition, 1 of thick cloth
Regarding step processing, defects such as bleeding on the back surface were likely to occur. According to the method of the present invention, excellent double-sided transfer printing can be carried out by one-step processing, and since no water is used, the environment is not adversely affected.

The heat treatment temperature for double-sided transfer printing in the present invention is preferably 150 ° C. to 250 ° C. from the viewpoint of color developability. Further, the heat treatment time of the double-sided transfer printing in the present invention is preferably 20 seconds to 2 minutes from the viewpoint of texture and productivity.

If the heat treatment temperature of the transfer printing is less than 150 ° C., it is not practical because the coloring property is poor unless a sufficient time is taken, and if it exceeds 250 ° C., not only the texture becomes hard but also the show-through occurs. It is not preferable because On the other hand, if the heat treatment time for transfer printing is less than 20 seconds, the color developability deteriorates, and if it exceeds 2 minutes, the texture becomes hard and the productivity deteriorates, which is not preferable.

In the fabric of the present invention, when a color pattern is provided by simultaneous double-sided transfer, both sides of the fabric are simultaneously transferred and printed with 10BG V5 / C8 colors of a standard hue according to JIS Z-8721 (ΔE). Is preferably 5 to 15. When ΔE is less than 5, show-through occurs when it overlaps with another color, and when it exceeds 15, color development on the front and back becomes insufficient, which is not preferable.
