Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for dyeing patterns similar to vegetable dyeing.

``Prior Art'' In general, the following methods were used to dye patterns similar to vegetable dyeing. That is, first, the base dyeing is applied to the squeezed fabric, and then about half of the liquid is removed. After spreading this dyed fabric on a flat plate,
The common method is to apply a dark dye with a spray or brush, dry it as it is, then fix the color and apply post-treatment. A manufacturing method has been proposed in which folds are actively formed on the grid lines, and the folds are used to generate light-colored areas in the form of wrinkles on the grid lines. Other similar technical documents include Japanese Patent Publication No. Sho 51-42237, which describes a method for dyeing various shades of color. The pattern that emerges from the dye layer is dyed onto the fabric by means of this method.
In addition, in Japanese Patent Publication No. 59-36036, there is a continuous dyeing method for a suminagashi pattern, the gist of which is that a dye such as India ink or ink made by mixing pigments and oil is continuously dropped onto the flowing water surface of a dyeing tank to form a dyeing liquid. This dyeing liquid is then stirred to form a turbulent flow pattern on the flowing water surface, and this turbulent flow pattern is absorbed and dyed onto the material to be dyed.

``Problems to be Solved by the Invention'' The above-mentioned prior art methods of blurring patterns using sprays, brushes, etc. require an extra step and are difficult to work with, and the scattering of dyes, etc. caused by spraying has a negative impact on the human body. There are hygiene problems. Furthermore, in the conventional brush painting method, the areas dyed by the brush inevitably become dark colored or dyed unevenly, and the design is not beautifully dyed, and there is a risk that the design may become monotonous. Further, in Japanese Patent Publication No. 51-42237 and Japanese Patent Publication No. 59-36036, shading patterns, turbulence patterns, etc. can be dyed, but patterns similar to vegetable dyeing, which is the object of the present invention, cannot be dyed at all.

In particular, in conventional dyeing methods, brush dyeing is applied to the dyed fabric before it dries, so in the case of tied fabrics, the transfer of the dye liquid to the tied areas is not sufficient, resulting in changes. There is nothing interesting about it. Furthermore, after dyeing, it is necessary to carry out further dyeing such as brush dyeing or spray dyeing, resulting in two steps, which are laborious and time consuming, and there are problems such as high costs.

``Means for Solving the Problems'' Therefore, the present invention provides a method for dyeing beautiful patterns similar to vegetable dyes with one bath of dip dyeing.
The gist is that dried shibori fabric or dry white fabric is immersed in a dye solution and dyed to a predetermined color. Alternatively, remove about half of the dye solution from the dyed fabric.

Then, this dyed and dyed fabric or finished dyed fabric is spread or folded and placed on an air-blocking member such as vinyl spread on a flat plate such as a drying shelf or a mesh provided on a drying shelf, etc., and dried one by one. Go ahead, 2-3
Dry it for about a day.

In this drying process, the areas that have been dried first are dyed in different shadings using capillary action (by transferring the dye liquid), and are dyed in one-bath dip dyeing of the dried squeezed fabric, etc. By allowing a sufficient drying time of about 3 days, the color can be evened out even in the squeezed areas or folded areas, and dyed in shading.

It is characterized in that it is then subjected to heat treatment by a conventional method.

"Embodiment and Effect" Next, an embodiment of the present invention will be described based on the drawings.

First, the first invention will be explained based on FIG. 1. As shown in FIG. 1 (b), a dried squeezed fabric 1 is immersed in a pigment in a dyeing tank 2 and dyed by so-called one-bath dip dyeing. After that, as shown in Figure C, the dyed squeezed fabric 1a is dehydrated through the dehydrator 3, and approximately 50% of the dye liquid is removed.
About % of the liquid is removed. The dyed tied fabric 1a, which has about 50% of the liquid removed in this way, is as shown in Figure D.
If vinyl 4 or the like laid out on a flat plate of a drying rack (not shown) is spread out in a diffused manner on a horizontal processing device, and air is allowed to move freely on the surface side of the finished dyed squeezed fabric 1a. Due to the movement of the wind, a predetermined portion of the dyed and tied cloth 1a that is well-ventilated is dried. The dye liquid moves in the direction of this dried predetermined area, and due to the so-called capillary action, the dye liquid moves to this area and is absorbed there, so that this area becomes darker first. It will dye. It's called changing colors. Such migration and absorption phenomena progress sequentially according to the parts of the dyed tied fabric 1a that are dried, and the color fading progresses, and as the drying of the dyed tied fabric 1a is completed, ultimately the first part of the dyed tied fabric 1a The parts that are first dried are colored in a dark color, and the parts that are dried later are gradually colored in a light color, until the color fading has almost stopped. Generally, the transfer and absorption of the dye solution is almost completely stopped in the half-dry state, and only a small amount is transferred and absorbed to the area that is subsequently dried.
This area is like ground dyeing and is given the lightest color. As a result, the dyed shibori fabric 1a
The shading is formed from the area that is dried first to the area that is dried later. Usually, color fading and drying are completed in about 2 to 3 days. By allowing sufficient drying time of about 2 to 3 days in this way and by using dried squeezed fabric when performing the one-bath dyeing process mentioned above,
The dye solution can be transferred to the squeezed area, and a shading pattern (dyed in light and shade) can be easily created at the squeezed area.

Thereby, a plant-like pattern can be generated. Drying can also be done by forced drying using hot air. After drying, similar to traditional tie-dyeing, the fabric is heat-treated by cylinder drying, the threads are removed, steam is applied to the fabric, the width is increased, and an iron finish is applied to create a design that is very similar to single-color vegetable dyeing. Further, in place of the above-mentioned pigments, reactive dyes, threne dyes, etc. can be used to dye patterns similar to vegetable dyes using the same dyeing method. However, in this case, it is necessary to react and fix the dye after the above-mentioned drying and color fading are completed. For example, it is recommended to do the following. For reactive dyes, threne dyes, etc., treat with caustic soda, hydrosulfite conc., etc. to fix the dye. Either by reacting and fixing it on the dyed dyed fabric 1a, or by treating it with high-pressure steam in a steamer or the like for direct dyes and acid dyes,
The dye is reacted and fixed on the dyed and squeezed fabric 1a.
After that, the same processing as in the conventional method is performed. Also, if you want to tie-dye the squeezed part 1b of the tied-up fabric 1 in a dark color in advance and make the ground dyeing a pattern similar to vegetable dyeing, use the same method as in the above example by changing the color of the ground dyeing to a lighter color than the density of the drawing part 1b. You can enjoy a wide variety of colors and designs by dyeing it through various manipulations. When dyed in this way, it is possible to obtain multi-colored products with patterns similar to those dyed with plants, which had previously been considered difficult.

Next, the second invention will be explained based on FIG. 2. As shown in FIG. It is dyed using what is called a one-bath dyeing process. Thereafter, as shown in Figure C, the dyed fabric 8a is dehydrated through the dehydrator 3, and approximately 50% of the dye liquid is removed. The dyed fabric 8a, which has been dehydrated by about 50% in this way, is placed on a horizontal processing device such as vinyl 4 laid out on a flat plate of a drying rack (not shown), and folds 9 are formed on it, as shown in Figure D. When the dyed fabric 8a is placed on the dyed fabric 8a and air is allowed to move freely on the front side, the movement of the air dries the predetermined portions of the folds 9 in the dyed fabric 8a through which the air passes. The dye liquid moves in the direction of this dried predetermined area, and due to the so-called capillary action, the dye liquid moves to this area and is absorbed there, so that this area becomes darker first. It will dye. It's called changing colors. Such migration and absorption phenomena progress sequentially according to the parts of the folds 9 that are dried within the dyed fabric 8a, and as the drying of the dyed fabric 8a is completed, ultimately the folds that are dried first are There is a dark color in the fold 9 area,
After that, the parts of the folds 9 that are dried are gradually colored with a light color, and the color fading is almost stopped.
Generally, the transfer and absorption of the dye liquid is almost stopped in the half-dry state, and only a small amount of transfer and absorption occurs in areas other than the folds 9 that are dried afterwards, and this area is similar to ground dyeing. The lightest color is assigned. As a result, the areas of the folds 9 that are dried at the inner tip of the dyed fabric 8a are colored in a dark color, and the areas other than the folds 9 that are dried later are gradually colored in a light color. Usually, color fading and drying are completed in about 2 to 3 days. By allowing sufficient drying time of about 2 to 3 days in this way and by using dried white fabric when dyeing in one bath as mentioned above, the dye solution can be transferred to the folds 9. This makes it possible to easily create a shading pattern (dyed in shading) even in the folds 9.

Thereby, a plant-like pattern can be generated. Drying can also be done by forced drying using hot air. After drying, like traditional tie-dyeing, it is heat treated by cylinder drying etc., then steam is applied to make the width.
The design is dyed by applying an iron finish. Also, instead of the pigments mentioned above, reactive dyes,
Vegetable-dyed similar designs can be dyed using a similar dyeing method using threne dyes and the like. However, in this case, it is necessary to react and fix the dye after the drying and color fading described above are completed. For example, it is recommended to do the following. For reactive dyes, threne dyes, etc., treat with caustic soda solution, caustic soda, hydrosulfite conc., etc. The dye is reacted and fixed on the finished dyed fabric 8a, or in the case of direct dyes and acid dyes, it is treated with high pressure steam in a steamer or the like, and the dye is reacted and fixed on the finished dyed fabric 8a. After that, the same processing as in the conventional method is performed. For shirts, etc., if you want to dye substantially the same pattern on both the front and back sides of the finished dyed fabric 8a, as shown in the figure (E), a horizontal treatment device for ventilation members such as the net 5 is hung on the drying rack, and this horizontal treatment is carried out. Finished dyeing fabric on the device 8
A is provided with folds 9 and placed. Then, the wind hits both the front and back sides of the folds 9 of the finished dyed fabric 8a, and the substantially same folds 9 on both the front and back sides are dried in the same way starting from the part of the folds 9 that is hit by the wind. Therefore, as in the previous example, the dark dye liquid is transferred to and absorbed by the front and back folds 9 that are dried first, giving them a dark color, and then the front and back folds 9 that are sequentially dried. The light-colored dye liquid is sequentially transferred and absorbed to areas other than the folds 9, giving them a light color. So-called color correction is performed. Thereafter, substantially the same pattern is dyed on the front and back folds 9 of the dyed fabric 8a by following the same process as described above.

[Effects of the Invention] The present invention is a dyeing method detailed above, in which so-called dry squeezed fabric or white fabric is dyed by one-bath dyeing. After that, about half of the dye liquid is removed from this dyed and tied fabric or dyed fabric, and then this drained dyed and tied fabric or finished dyed fabric is spread horizontally or placed with folds on an air blocking member, etc. The structure is such that the dye solution is transferred and absorbed by allowing sufficient drying time of about 2 to 3 days, and by wind movement and capillary action.

Therefore, by dyeing in one bath, deliquing about half of the liquid, and taking a sufficient drying time of about 2 to 3 times, it is possible to dye patterns similar to vegetable dyes. ,
Helps simplify and speed up work without requiring processes such as brush dyeing. You can also enjoy the beautiful patterns similar to those dyed with plants.

Furthermore, since it is a one-bath dip dyeing method, it is possible to prevent human accidents caused by the diffusion of dyes that would otherwise occur with brush dyeing, making it a truly useful invention.

In particular, the present invention uses a dried squeezed fabric or white fabric during one-bath dyeing, and after removing about half of the dye liquid from the dyed tied fabric or finished dyed fabric, an air-blocking member such as vinyl or a ventilation member is used. The parts are spread or folded and placed, usually 2 times.
This is a method of color fading and drying over a drying time of about 3 days, and because it takes a sufficient drying time of about 2 to 3 days, it is possible to transfer the dye liquid to the squeezed areas or folded areas. Therefore, it is possible to easily create a shading pattern (dyed in shading) even in the drawing area or the fold area, thereby making it possible to create a pattern similar to plants.

Furthermore, in the present invention, after one-bath dip dyeing, about half of the dye liquid is removed from the dyed tied fabric or finished dyed fabric, and then the fabric is spread or folded and placed on an air blocking member or ventilation member such as vinyl. Well, 2~
Since this method takes a sufficient amount of time, about three days, to fade and dry the color, no skill is required, the work can be simplified, and the product can be provided at a low price. It also allows you to easily dye your favorite designs.
