Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is a method of dyeing and discharging a large number of sewn cloth products, such as clothes, bags, aprons, etc., at once, and each item is unique. This relates to possible processing methods.

(Conventional technology) Traditional processing of cloth products such as due east and discharge printing.

Most of them have been done before sewing. Some, im
Although there have been cases where each item is individually processed by hand, the conventional printing and discharge printing methods mainly revolve around a horizontally long drum with a pattern engraved on it, and then the fabric is placed on the pattern-engraved surface. There are two methods: one method is to print a pattern onto the cloth continuously by placing it in close contact with the cloth, and the other method is to print a patterned screen onto the cloth while running the cloth on a flat surface. In addition, there is a dyeing method in which the fabric is partially squeezed with thread, dipped in a dye solution, and the squeezed thread is removed during post-processing, resulting in a mottled pattern in areas where the dye solution has not penetrated, and resist dyeing on the fabric. This is the Shinto process, in which a dye is partially applied and immersed in a dye solution, and the resist-dyed areas are not dyed.

In contrast to these conventional techniques, as a processing method that gives a worn-out feel even if it is new and finishes the product with a unique color tone, the denim fabric is physically rubbed and partially dyed. The present inventor has previously proposed a method in which the inside of the core is exposed and the inside of the core is piece-dyed with a color different from the color of the yarn-dyed yarn (
JP-A No. 58-8192).

<Problems to be solved by the invention> However, all of the textiles that have been printed using the methods described so far either have a uniform pattern or are processed before product packaging, so this is not suitable for sewing. If the pattern is cut at the seam of the product, the unnaturalness of the pattern will be clearly visible.Furthermore, even if the pattern is matched during sewing, there will be loss of fabric during cutting, and the product will become standardized. The problem was that it could not be the highly individualized and unique product that is required of modern Fatsujicoms.

Therefore, the dyeing and discharge printing method of the present invention allows each product to have its own individuality regardless of the number of products, and it is possible to obtain products that are significantly different from products produced by conventional processing methods. That is.

In the present invention, a sewn fabric product is stirred in a gas phase container in the presence of a mixture of one or more of oxidizing agents, reducing agents, dyes, etc. and granular solids for polishing.

It is characterized by dry processing.

If the fabric product is sewn from various types of plain dyed fabrics, such as indigo-dyed jeans, no dye is used and only an oxidizing agent or reducing agent is used; if the fabric is sewn from a white fabric, a dye and an oxidizing agent or reducing agent are used. Add reducing agent. Further, a granular solid substance for polishing is added, and the material is rotated in a tank of a horizontal rotary washing and dyeing machine in a vapor phase while applying humidity and temperature using steam, etc., and a pattern is imparted by frictional contact. After the former discharge printing process, the latter process performed on the white fabric can be repeated using another dye.

The oxidizing agent used here is sodium hypochlorite, potassium permanganate, etc., and the reducing agent is hydrosulfide, sodium sulfide, etc. Dyes include basic dyes, oxidation dyes, sulfur dyes, and direct dyes.

Select appropriate dyes such as thren dyes and reactive dyes depending on the type of cloth product.

Granular solid materials for abrasive use include river bottom stones containing eggs, crushed stones, volcanic lapilli, pumice, various artificial abrasive materials or their sintered bodies, and even plastic granules and wood chips. Use A, German, or a mixture.

It is convenient to use a horizontal rotary washing machine for the stirring process in the gas phase container, and the gas phase does not refer to the dry state, but rather to the conventional dyeing and discharge printing in a liquid. In other words, at least there is not much free liquid present, and as mentioned above, it is a process in which temperature and humidity are applied with water black air or free water is removed by squeezing the sewn product.

Effects> The dyeing and discharge printing method of the present invention is for processing sewn fabric products in a gas phase container where the processing liquid does not exist as a liquid phase.

A granular solid material to which one or a mixture of two or more of oxidizing agents, reducing agents, dyes, etc. is attached is brought into contact with the m-product.

As a result, the contact area is oxidized, reduced, or dyed, resulting in a product with individually different patterns.This is a unique method.

EXAMPLES The present invention will be specifically explained below using Examples.

<Example 1> Approximately 50 kg of a product sewn from plain dyed blue fabric without a pattern was placed in a horizontal rotary washing machine approximately 2 inches in size.
In another container, add bleaching solution (sodium hypochlorite solution) for about 10 minutes.
I have prepared Q. In this bleaching solution, add about half of 80% of river stones as granular solids (in addition, crushed river stones, plastics, artificial stones, etc.)
The sample was immersed as a liquid, then pulled out, added to the washing and dyeing machine, and rotated in a gas phase for about 30 minutes. Rinse with approximately too much water, and after draining, add 5 kg of sodium thiosulfate.
After performing bleaching solution (chlorine) removal treatment for about 30 minutes with 1,000 fi water, washing was performed with 10,000 fi water. As a result, the contact between the product and the granular solid matter to which the bleaching solution has adhered and the promotion of oxidation by the gas phase whiten out those areas, giving each product a random pattern in two different colors: blue and white. I was able to do it.

As the bleaching liquid used in such a processing method, bleaching powder or other bleaching solids may be used as necessary, and reducing agents such as hydrosulfides may also be used instead of these oxides.

<Example 2> Approximately 50 kg of plastic granular solids (wood chips etc. can also be used) and direct dye (Kayarasuji-5 manufactured by Nippon Gunpaku@)
Mix 500g of Lit BWs) with 200g of paste and 3Q of water to make a slurry, and simultaneously put it into a drum-type rotary washing machine with a size of about 2 bottles and wash it in the vapor phase.
Rotate for 5 minutes to evenly coat the dye on the solids. Next, 30 kg of a product sewn on an undyed white background was added and rotated for 200 minutes in the gas phase, then 10 kg of salt was added, and the rotation was continued for another 15 minutes.
Washed with water for 5 minutes. This washing with water is 2I! After 1 trip,
Dye fixative 1- was diluted with 50012 water and rotated for 10 minutes.

The products obtained by the dyeing and discharge printing method described above are processed in the gas phase, so unlike dyeing in the liquid phase, which is usually done, the product comes into contact with the solid matter to which the dye is attached. Because the color is uneven, the product has been given a variety of dyed patterns. The dyes used in this process include direct dyes, as well as reactive dyes, sulfur dyes, threne dyes, and pigments.
It may be used depending on the purpose, such as color fastness and tone (for example, clarity, dullness, etc.).

<Example 3> The product processed in Example 1 has a pattern consisting of two colors: the blue background color is whitened out and a white part, and the blue background color. This product was once dried and subjected to the same dyeing and discharge printing method as in Example 2. Mix 500 g of yellow direct dye (Kayarasupura Yellow RL, manufactured by Nippon Kayaku ■) with 300 g of glue and 3 Q of water to form a slurry. 50 kg of the solid material and the slurry dye are placed in a 2-drum rotary washing machine and rotated in the gas phase for 15 minutes to evenly adhere the slurry dye to the solid material, and then the product is washed. (The above-mentioned blue, white, white background due east) 30 kg was added and rotated for 20 minutes.

The resulting product is a two-color product, blue and white, with a yellow pattern dyed on it, where the solid material that retains its yellow color on the blue background becomes green, and where it comes in contact with the white background, it becomes yellow.
It now has a pattern of blue, green, and white.

<Effects of the Invention> The present invention is a method for dyeing and discharging sewn products as described in detail above, and although it is a method that can process a large number of products at once, each product has its own unique characteristics. It has the advantage of being able to meet the highly individualized needs of modern fashion.

that's all
