Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to fabrics such as woven fabrics, knitted fabrics, and non-woven fabrics (hereinafter referred to as
In the present invention, it is simply referred to as cloth. ), more specifically, it relates to a method for rendering a blurred wrinkle pattern.

[Conventional technology]

Normally, the wrinkle pattern can be created by Shibori dyeing, Rouketsu dyeing, or print printing.In order to make the wrinkle pattern blurred, a multi-dye adsorbent is used (Jikkosho).
54-37904), or by causing the dye to bleed (Special Publication No. 55-8636), or in the case of print textile printing, by gently changing the depth of the engraved periphery of the engraving roll (Special Publication No. 57-23039); For example, a method is used in which printing is performed several times while shifting the edges of the printing screen (Japanese Patent Publication No. 58-28395).

[Problem that the invention seeks to solve]

In Shibori dyeing and Rouketsu dyeing, the areas other than the areas to which the dye solution is applied are strongly resist-dyed, and it is impossible for the dye to penetrate deep into the resist-dyed areas due to bleeding, especially when dyeing. If the liquid is not directly applied and the area of the light-colored (undyed) area that is darkly bordered by wrinkle lines is large, it is impossible to depict a blurred wrinkle pattern in which the color of the entire light-colored area changes gently. I can't.

In this respect, Special Publication No. 57-23039 and Special Publication No. 58-28395
The printed textile printing method described in this issue allows for large, blurred, wrinkled patterns, but in order to do so, it is necessary to prepare a number of engraving rolls depending on the degree of change in density, or to perform squeegeeing several times. Therefore, the process is complicated, inefficient, and the manufacturing cost is high, making it economically impractical.

Above all, it is practically impossible to finely and randomly change the color density and blurring pattern of the dark colored part of the crease line and the light colored part surrounded by it. It is not possible to print a symmetrical crumpled pattern.

[Purpose of the invention]

Therefore, in the present invention, the crease lines in the dark color part are finely branched at random in color density, curved shape, thickness, and continuous length, and the light white part is dyed with the same dye as the dark color part, giving a random color density. In addition, the color density changes randomly and smoothly at the boundary between the dark and light areas.The front and back of the blurred wrinkle pattern, which is color-coded into the dark and light areas, is symmetrical on the front and back. The purpose is to provide a simple depiction of the

[Structure of the invention]

The present invention meets the above objectives,
The dye solution is applied to the outer surface of the yarn, leaving unattached areas inside the threads that make up the fabric, then creasing the fabric, and then spreading the fabric to a temperature below the color development temperature of the dye. It is characterized in that it is dried by heating at a temperature range of 100 mL, and then heated and colored at a temperature higher than the coloring temperature of the dye to produce a crumpled pattern.

That is, in the present invention, prior to the heat coloring treatment after applying the dye solution in the normal plain dyeing process, the fabric is made into a wrinkled state, and the fabric is preheated while being spread to such an extent that the wrinkles do not completely disappear. drying by causing migration of the dye, and performing the migration of the dye during preheating in a state where the dye does not completely penetrate between the internal fiber elements of the threads that make up the fabric; The method is characterized in that the coloring process is carried out after migration has occurred in the dye, and the gist is to thereby produce a blurred crumpled pattern symmetrically on the front and back.

In other words, the present invention deals with wrinkles that occur during the unloading process after weaving on fabric to which the dye has been applied prior to heat coloring treatment, or on fabric that has been piled up after the scouring and bleaching process, in the normal plain dyeing process. Focusing on the fact that when creases, etc. remain without being removed, migration occurs during the heating coloring process and the dye moves to the creases, creating staining spots, we actively utilize the inconveniences that occur in the conventional dyeing process. This is the object of the present invention.

In the present invention, in order to control the extent of migration, it is recommended to add a small amount of a commonly used anti-migration agent to the dye liquor. It is recommended to add a tackifying agent (such as a sizing agent) to the dye liquid in order to prevent it from penetrating and easily cause migration.

The dye liquor may be applied to the fabric by dipping, spraying, printing, or floss coating (foaming and applying the dye liquor).

In other words, in order to leave unattached parts of the dye inside the yarn and apply the dye to the outer surface of the yarn, if the yarn is a thick spun yarn or a strongly twisted yarn, the fabric must be prepared for depping and dyeing. However, if the yarn is one that easily penetrates the dye liquid to the shaft core, such as fine-count spun yarn or bulky untwisted or lightly twisted yarn, a tackifying agent may be used. The dye solution is blended with the dye to thicken it, or the dye solution is foamed to make it difficult for it to penetrate inside.

The dye to be used is not particularly limited and can be appropriately selected depending on the type of fabric fiber, but hot type reactive dyes with slow dyeing reaction, particularly dry coloring type reactive dyes are recommended.

It is best to temporarily set the wrinkles on the fabric after applying the dye solution.
Special Publication No. 56-5867, Special Publication No. 57-19223, Special Publication No.
58-39946 etc. may be applied.

The fabric is not limited to plain fabrics, but also patterned fabrics such as jiya guards and prints, as well as fabrics with a blurred wrinkle pattern according to the present invention. Complex patterns may be created, or an alkaline agent may be added to the dye solution for cellulose fiber fabrics, or glyoxal or other resins may be added to the dye solution for synthetic fiber fabrics, or the drying temperature may be set to a high temperature to cause migration of the dye, or heat coloring treatment may be applied. Afterwards, the fabric is temporarily set by high-temperature heat treatment, etc., and the uneven wrinkles that remain on the fabric are strongly set to the extent that they will not disappear by washing etc., thereby creating shadows along the contours of the uneven wrinkle pattern. It is also within the technical scope of the present invention to create a pattern that is more complex and rich in three-dimensional effect by dyeing it in different shading and lightness in a blurred manner.

Hereinafter, the present invention will be specifically explained with reference to Examples.

[Example] A liquid bath prepared by blending a plain-woven cotton cloth 16 with a basis weight of 200 g/m ² with a dry heat coloring type reactive dye, urea, sodium bicarbonate, a very small amount of a tackifying agent (glue), and a migration inhibitor. 17, and after lightly squeezing the liquid with a mangle 18, the fabric is compressed into a string-like width on an inclined plate 19, and then folded in the length direction and rolled up to create wrinkles randomly in the vertical and horizontal directions, and then rolled into a dumpling shape. machine 20
The wrinkles are temporarily set by pressing, and the temporarily set wrinkles are pulled out while expanding to the extent that they do not disappear completely, and then dried by passing through a thermal radiation heating device (non-touch surface heating gas burner) 21 in a non-tensioned state. was passed through a heating coloring device 22 according to a conventional method, post-treated with a winch, and dried in a tumbler.

In the cotton cloth 14 dyed in this way, the dye moves (migration) to the convex portions of the temporarily set wrinkles during the drying process before coloring treatment, and the convex portions of the temporarily set wrinkles develop a dark color symmetrically on the front and back of the fabric. This results in a wrinkled dark colored part 11, and this dark colored part 1
In the area surrounded by 1, there is less dye and the wrinkles become lighter, and the folded shape, thickness, and continuous length of the wrinkles are created by randomly branching into many fine branches, so that the dark colored area 11 in the form of crumpled lines and the dark colored area are formed. The crumpled lines 13 of the dark colored part 11 have color density, bent shape,
The thickness and continuous length are random and there are many finely divided branches, and there are randomly blurred dyed spots 14 in which the light colored part 12 is dyed with the same dye as the dark colored part 11, and the dark colored part 11 and the light colored part 12 are different. At the boundaries, the color density changed smoothly and randomly, and the boundaries were blurred, giving a visually rich three-dimensional effect.

〔Effect of the invention〕

According to the present invention, the dark color portion 11 forming the crumpled pattern
The crease lines 13 occur along the crease traces applied before the heat coloring treatment, and therefore, their length and density can be freely determined depending on how the creases are applied, that is, whether or not the fabric is tightly bundled or folded. It can be adjusted. That is, the present invention uses a simple method of manually rolling the fabric into a dumpling and adding false creases in the process of dyeing the fabric into a single solid color. Wrinkling can be easily done by shaking it off on a trolley and storing it, and it does not require the troublesome labor of preparing a resisting paste that tends to cause cracks and creating cracks in the coating film. In addition, there is no need to worry about abnormal peeling or falling off of the resist coating, and there is no need for complicated processes or expensive equipment such as preparing multiple printing screens and engraving rollers and printing many times. Moreover, the present invention is easy to implement and practical.

The crumpled pattern created by the present invention is divided into shades of light and dark using migration that occurs randomly in the dye applied evenly to the front and back sides of the fabric. It is color-coded into a dark colored part 11 which is a wrinkled line with a random length and many fine branches, and a light colored part 12 surrounded by the dark colored part 11, and the light colored part 12 contains the same dye as the dark colored part 11. However, randomly blurred staining spots 14 occur, and at the boundary between the dark color area 11 and the light color area 12, the color density changes smoothly and blurs at random, and the crease lines 13 of the dark color area 11 and the light color Due to the difference in density between the dyed spots 14 in the area 12, a sense of perspective is created in each of these parts, and the outline of each part has a blurred color density and is unclear, and the overall tone is soft, and there is a crumpled pattern due to the difference in shading. Since the front and back sides are symmetrical, the colors are deep and a novel printed fabric with a three-dimensional effect that has never been seen before can be obtained. Therefore, the present invention is extremely advantageous.

Furthermore, in the present invention, migration occurs significantly because it is carried out in a state in which the dye is easily moved immediately after the application of the dye solution, which does not penetrate between the fibers inside the yarn, and as a result, the light colored areas are also resist-dyed. The advantage of the present invention is that it is possible to create a crumpled pattern with a sharp difference in shading as a whole, even though the white areas are formed and the areas between dark and light colors are blurred. However, it is extremely large.
