Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a method for creating a crumpled pattern on fabrics such as woven fabrics, knitted fabrics, and non-woven fabrics (hereinafter simply referred to as fabrics in the present invention);
More specifically, the present invention relates to a method for depicting a blurred wrinkle pattern.

[Conventional technology]

Usually, the crumpled pattern can be drawn by Shibori dyeing, Roukera dyeing, or print printing, and in this case, to make the crumpled pattern blurred, a multi-layer dye adhesive is used (Utility Model Publication No. 54-37904)
Or cause the dye to bleed (Special Publication No. 55-8636)
No.) or in print printing, the depth of the engraved periphery of the engraving roll is changed gently (Special Publication No. 57-23039)
(No. 58-28395), or 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 Roukera dyeing, the areas other than the areas to which the dye liquid 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 the dye liquid is applied. If the area of the light-colored (undyed) part that is not directly applied and is darkly bordered by wrinkle lines is large, it is impossible to create a blurred wrinkle pattern in which the color of the entire light-colored area changes gently.

In this regard, Special Publication No. 57-23039 and Special Publication No. 58-28
With the print printing method related to No. 395, it is possible to create a large blurred and wrinkled pattern, but for this purpose, it is necessary to prepare a large number of engraved rolls depending on the degree of change in BFI or to print several times. The process is complicated and 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 crumpled lines in the dark color area have color density, curved shape,
The thickness and continuous length are finely divided at random, and the light white part is dyed with the same dye as the dark color part, creating a east tower pattern with randomly changing color density, and the dark and light color parts are dyed with the same dye as the dark color part. The purpose of this invention is to simply depict a blurred crumpled pattern, which is color-coded into dark and light areas, with the color density changing randomly and smoothly at the boundary between the front and back, symmetrically.

[Structure of the invention]

The present invention satisfies the above-mentioned objectives, and is capable of completely eliminating wrinkles by making the fabric wrinkled prior to heat coloring treatment after applying the dye solution in a normal plain dyeing process. Drying is performed by preheating the cloth while spreading it to such an extent that it does not cause migration of the dye, and the state in which the dye does not completely penetrate between the internal fibers of the threads that make up the fabric. Therefore, it is characterized in that the heating coloring treatment is carried out after causing migration in the dye, and the gist thereof is to thereby render a blurred wrinkle pattern symmetrically on the front and back sides.

That is, 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 fabrics that have been stacked 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 an east tower, we actively utilize these 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 degree of occurrence of migration, it is recommended to add a small amount of a commonly used anti-migration agent to the dye solution, and also to prevent the dye solution from penetrating between the cellulose inside the yarn before preheating. An activator (such as a sizing agent) may be added to the dye liquor in order to facilitate migration.

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

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

It is best to temporarily set wrinkles on the fabric after applying the dye solution, and for the wrinkle treatment, Japanese Patent Publication No. 55-32827, Japanese Patent Publication No. 56-5867, Japanese Patent Publication No. 57-19223, Japanese Patent Publication No. 58-39946 The means related to the above may also be used.

The fabric is not limited to plain fabrics, but can also be used with jacquard or printed patterned fabrics with a blurred crumpled pattern, and by adding the blurred crumpled pattern of the present invention to such patterned fabrics, it can be made even more complex. with a pattern, or
For fabrics made of cellulose fibers, an alkaline agent is added, and for fabrics made of synthetic fibers, glyoxal or other resin is added to the dye liquor, or the drying temperature is set to a high temperature to cause migration of the dye, or a high temperature heat treatment is applied after heat coloring treatment. The uneven wrinkles that are set and remain on the fabric are strongly set to the extent that they will not disappear by washing, etc., and then dyed in different shading to create a more complex and three-dimensional appearance. It is also within the technical scope of the present invention to create a pattern that is rich in sensation.

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

〔Example〕

A plain woven cotton cloth 16 with a width of 200 g/= is mixed with a dry heat coloring type reactive dye, urea, thorium bicarbonate, and a very small amount of activator (glue).
Liquid bath 17 prepared by blending and anti-migration agent
After immersing the carp in water and squeezing it lightly with the mangle 18, remove the carp from the swash plate 19.
The width of the fabric is shortened into a string shape, and then folded in the length direction and rolled up to create wrinkles randomly in the vertical and horizontal directions. Pull it out while enlarging it to the extent that it does not disappear completely, and dry it by passing it through a thermal radiation heating device (non-touch exothermic gas burner) 21 in a stress-free state, then pass it through a heating coloring device 22 according to the usual method, and finish it with a wince. process,
It was dried in a tumbler.

In the cotton fabric 14 dyed in this way, during the drying process before coloring treatment, the dye migrates to the convex portions of the temporarily set wrinkles, and the convex portions of the temporarily set wrinkles develop a deep color symmetrically on the front and back of the fabric. The dark colored part 11 has a wrinkled line shape, and the part surrounded by this dark colored part 11 has less dye and becomes lighter, and the wrinkles are created by branching into many small pieces with random bending shapes, thicknesses, and continuous lengths. Therefore, it has a crumpled pattern with a symmetrical pattern on the front and back, which is color-coded into a dark colored part 11 in the form of crumpled lines and a light colored part 12 surrounded by the dark colored part 11. The color density, curved shape, thickness and continuous length are random and there are many fine branches, and even though the light colored part 12 is dyed with the same dye as the dark colored part 11, there are randomly blurred staining spots 14, At the boundary between the dark-colored area 11 and the light-colored area 12, the color density changed smoothly and randomly, and the boundary between them was blurred, giving a visually rich three-dimensional effect.

〔Effect of the invention〕

According to the present invention, the crease lines 13 of the dark colored part 11 forming the crease pattern are generated along the crease traces applied before the heat coloring treatment, and therefore, the sharpness and density of the crease lines 13 depend on the appearance of the creases. In other words, it can be freely adjusted by whether or not to bundle or fold the fabric. That is, the present invention utilizes a simple method of manually rolling up the fabric into a dumpling shape and inserting a plate part in the process of dyeing the fabric into a normal plain color. There is no need for complicated labor such as shaking it off on a trolley etc. and storing it, there is no need to worry about the peeling off of the resist coating film, and there is no need to waste many printing screens and engraving rollers. The present invention is easy to implement and practical, as it does not require a complicated process of multiple printing or expensive equipment.

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 area 11 with many finely branched wrinkle lines at random, and a light-colored area 12 surrounded by the dark-colored area 11. Although it is dyed, 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 line I3 of the dark color area 11 and the light color area A sense of perspective is created in each part due to the difference in density between the 12 stained spots 14,
The color density of the contours of each part is blurred and unclear, and the overall color tone is soft.However, since the crumpled pattern created by the difference in shading is symmetrical on the front and back, the colors take on a deep depth, creating a three-dimensional effect that has never been seen before. The present invention is therefore highly advantageous as it provides new printed fabrics that are rich in color.

Furthermore, in the present invention, the migration occurs immediately after the application of the dye liquid, which does not penetrate between the fibers inside the yarn, and in a state where the dye is easily mobile, so that the migration occurs conspicuously. The advantages of the present invention are extremely large, such as the ability to create a crumpled pattern with a clear difference in shading as a whole by forming a white part and creating a pokashi-like tone between the dark and light colored parts. be.
