Abstract

PURPOSE:To efficiently and more clearly express a continuous or geometric multicolor pattern excellent in contigency, irregularity and variety exhibiting a high fastness on a silk-, cotton-, line-woven fabric, etc., in a short time while minimizing the amount of dyes and assistant agents. CONSTITUTION:This dyeing method is carried out characteristically by introducing a cationic group onto the whole or a part of the surface of a silk-, cotton-, line-woven fabric, etc., and subsequently superimposing two or more colors by the dip dyeing method. In comparison with an untreated fabric in the conventional method, a higher deep dyeing effect is obtained and dyeing can be instantaneously carried out. Dye bleeding or dye migration can be prevented and a clear pattern can be expressed. In addition, the amount of dyes or assistant agents required for dyeing is very small.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a textile dyeing method for expressing a naturally occurring pattern pattern on a textile by superposing two or more colors with an artificially selected dye.

[0002]

2. Description of the Related Art Conventionally, a dip dyeing method for expressing a naturally occurring pattern pattern on a fabric by stacking two or more colors of dyes on one another is a narrow cloth wrapping measure, a narrow wing scale of a silk woven fabric, or a squeezing process in the dyeing technique of a belt. It is used for dip dyeing such as roquettes, squeeze squeezing of woven fabrics, and squeezing plates.

[0003] The squeezing roquette is not a dyeing prevention method using a string or wax and is called a squeezing roquette because the dyeing is similar to roquette dyeing, and is also called a box dyeing squeeze.

[0004] This is a woven box containing bamboo mesh with a wooden frame, and a woven fabric which is sufficiently moistened, is arranged irregularly and appropriately with wrinkles, and the dyeing solution whose color tone has been adjusted is put into a watering can, a scoop, etc. Dye it by sprinkling it over the fabric, and then turn it over and dye the back side as well.

In the case of two or more colors, the cloth is once taken out from the cage of the cage and dyed by repeating this operation in the same procedure.

After performing uneven dyeing on both sides, it is sufficiently washed with water in a water tank and dried to finish, so that even if the woven fabric has Hikita squeezing or other binding, it can be dyed in a waxy tone.

The Muraun squeezing is also called a rod tightening squeezing. First, the woven fabric is folded in two lengthwise, and the seam portion is flat stitched with one thread to form a tubular shape. Moisten this cloth with water and cover it with a round rod or cylinder, and shrink it to the end with pleats.

The upper and lower sides of the woven fabric are firmly pressed, dipped in a dyeing solution of which color tone is adjusted, and rotated to dye. Alternatively, dyeing is performed by sprinkling a dyeing solution on the woven fabric with a watering can, a scoop, or the like.

If there are two or more colors, remove them from the stick once and wash with water.
After drying, the same procedure is repeated for staining. The dyed pattern can be expressed by irregular multicolored horizontal stripes.

The plate tightening is a dyeing technique for expressing a pattern by applying a template to a fabric and folding the fabric together with the effect of applying the template.

For this, not only the technique of applying a template to both ends of the folded fabric and the both ends of the folded fabric,
There is also a technique in which a template is sandwiched between folded fabrics.

The woven fabric fixed by this method is sufficiently moistened with water and then dipped in a dyeing solution of which color tone is adjusted for dyeing. Alternatively, dyeing is performed by sprinkling a dyeing solution on the woven fabric with a watering can, a scoop, or the like.

In the case of two or more colors, the template is once removed, washed thoroughly with water and dried, and then the same operation is repeated for dyeing.

The dyed pattern becomes a continuous pattern or a geometrical pattern having multicolor changes.

However, according to these methods, when a pattern of two or more colors is expressed with a high-density color tone, a long dyeing time is required to increase the density, and defective dyeing prevention causes a clear pattern. It's difficult.

At this time, a large amount of salt or acid is required to adsorb the dye.

In order to express a clearer pattern, there is a method of dye-resisting with a starch-based glue or the like, but the finish does not match well and the paste remaining on the fabric must be completely removed.

This requires washing with a large amount of water and treatment with a solution of the cellulolytic enzyme for a long time. For this reason, there is a high possibility that the expressed pattern will be out of order or that color flow will occur.

Cotton and linen fabrics can be dyed with anionic dyes such as direct dyes and reactive dyes.

When a cotton or linen fabric is dyed with a direct dye using a technique of squeezing a lozenge, a village cloud, and a plate-squeezing technique, various pattern patterns should be expressed in the same manner as dyeing with a silk fabric using the same technique. Is possible.

However, according to this method, a large amount of salt is required at the time of dyeing, and the finished product has poor dyeing fastness, so that it has not been commercialized so far.

When cotton, linen fabric is squeezed with a reactive dye to dye a lozenge, a Muramori squeezer or a plate tightening squeeze, a method of sprinkling a dye liquor on the woven fabric with a watering can or a scoop will not cause the dye to be fixed to the woven fabric. It is difficult to express the pattern because it flows.

Dyeing is possible with the method of immersing the Murakumo diaphragm and plate clamping diaphragm in a dye liquor, but since the dyeing takes a long time, it is clear when two or more colors are dyed with a high color tone. It is difficult to express a unique pattern.

In addition to this, there is a method of expressing by printing.
However, this method requires many kinds of dyes and paper patterns to express many hues with overlapping colors, irregular and changing continuous patterns, and geometric patterns, and it is profitable to spend time and effort. It is thought that it cannot be taken.

Further, if the woven fabric has a Hikita squeeze or other nails, this method is impossible.

From the above, it has been desired to put into practical use a method of efficiently expressing an accidental color or pattern on a fabric such as silk, cotton or linen.

[0027]

SUMMARY OF THE INVENTION The present invention relates to silk, cotton,
Fabrics such as linen have a high degree of fastness with a multicolored color with accidental color and continuous patterns or geometric patterns with irregularities and changes, and are efficient in a short time with the minimum necessary dyes and auxiliaries. The purpose is to express more clearly.

[0028]

According to the present invention, a woven fabric such as silk, cotton and linen is introduced with a cation group in whole or in part, and then an anionic dye is used to superimpose two or more colors by dip dyeing. The dyeing method is characterized by that.

In the present invention, as chemicals for introducing a cation group into textiles such as silk, cotton and hemp, 3-chloro-2-hydroxypropyltrimethylammonium chloride, glycidyltrimethylammonium chloride and 3-chloro-2-hydroxypropyldimethylammonium are used. Chloride, 3-chloro-2-hydroxypropyl-2-hydroxyethyldimethylammonium chloride and the like are used, and among them, 3-chloro-2-hydroxypropyltrimethylammonium chloride is extremely effective.

Alkali is used as an auxiliary agent for the introduction of the cation group, but NaOH, KOH, NaCO _{3 and the} like are effective, and in the case of silk fabrics, if the amount used does not affect the physical properties, the amount of NaOH is particularly increased. It is effective.

After the fabrics such as silk, cotton and linen are pretreated by using the above chemicals, they are dyed with anionic dyes of two or more colors by using the techniques of squeezing rockets, Muragumo squeezing and plate squeezing. I will.

Textiles such as silk, cotton, and linen having a cationic group introduced have a higher deep dyeing effect than untreated ones, and the dyeing is carried out instantly, resulting in a clear coloring without causing color flow or warming. It is possible to express various patterns.

Further, the amount of dyes and auxiliaries necessary for dyeing is extremely small compared with the dyeing of untreated fabric.

Next, the present invention will be described with reference to examples, but the present invention is not limited thereto.

[0035]

Example 1 A white background silk fabric was treated with 3-chloro-2hydroxypropyltrimethylammonium chloride (purity 60).
%) 40 g / l, 8 g / f NaOH solution at a bath ratio of 1:50 for 10 minutes to 20 minutes to 80 ° C., treated at 80 ° C. for 5 minutes, washed with water, and treated with 1 ml / l of acetic acid. It was washed with water and dried.

[0036] This white silk fabric is made of loxerine (1%),
Dyeing was performed with milling green (1%) acid dye using the techniques of squeezing squeezing, Murakumo squeezing, and plate tightening.

As a result, it was possible to express a continuous pattern in which irregularities and changes of various colors of various colors were dark and vivid without causing color flow or fanning.

[0038]

Example 2 A white background silk fabric was treated with 3-chloro-2hydroxypropyltrimethylammonium chloride (purity 60).
%) 40 g / l, 8 g / l NaOH solution at a bath ratio of 1:50 for 10 to 20 minutes to 80 ° C., treated at 80 ° C. for 5 minutes, washed with water, and treated with 1 ml / l of acetic acid. It was washed with water and dried.

[0039] This white background silk fabric is used for Shibacron Yellow F3
Squeeze with a reactive dye solution of R (1%), Cibacron Red FB (1%), Cibacron Blue FR (1%),
Using the techniques of Muramo diaphragm and plate tightening diaphragm, Na ₂ CO ₃
(1%) was dyed respectively. Cover this with a plastic bag for 17 hours or more so that the silk fabric does not dry as it is,
Leave at room temperature (20-30 ° C), wash with water, and soap 1
It took 0 minutes.

As a result, the untreated silk fabric was scarcely dyed, but a continuous pattern caused by irregularities and changes of various colors of each multicolor was produced in a dark color without causing a color flow or a fan. I was able to express it clearly.

[0041]

Example 3 White cotton and hemp fabrics were treated with a solution of 3-chloro-2hydroxypropyltrimethylammonium chloride (purity 60%) 80 g / l and NaOH 40 g / l at a bath ratio of 1:50 at room temperature for one day. , Washed with water 1m acetic acid
It was treated with 1 / l of acid, washed with water and dried.

This white cotton or linen fabric is squeezed with a reactive dye solution of Cibacron Yellow F3R (1%), Cibacron Red FB (1%) and Cibacron Blue FR (1%), a roquette, a village cloud squeeze, and a plate tightening squeeze. Na ₂ C
Each was dyed with O ₃ (1%).

To prevent the cotton or linen fabric from being dried as it is, it is covered with a plastic bag for at least 17 hours at room temperature (20 to 30).
It was left to stand at (° C.) and washed with water and soaping for 10 minutes.

As a result, the untreated cotton and linen fabric were scarcely dyed, but a continuous pattern with irregularities and changes of various colors of each color was produced without causing a color flow or a dull appearance. I was able to express clearly with color.

[0045]

As is apparent from the above examples, the present invention introduces a cation group into a fabric such as silk, cotton, or hemp in advance, so that the concentration which is a subject of the dyeing technique that has been conventionally performed. It is possible to express a pattern of two or more colors in a high color tone with high robustness and high vividness without causing color flow or blurring.

In addition, the dye and the auxiliary agent at the time of dyeing are extremely small compared with the conventional ones, and the dyeing time is short.

Until now, it has not been possible to express a commercial-valued pattern by dyeing untreated silk, cotton or linen fabric with a reactive dye. The fact that dyeing with reactive dyes has become possible also has high fastness, which can lead to higher added value.

In order to meet the diversifying needs of the modern age,
It can be said that the present invention, which is highly robust and can be variously expressed in fabrics such as silk, cotton, and linen, can be a means for developing highly original products in small lots, which have high added value as clothes, interior materials, and the like.
