Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for dyeing textiles by dip dyeing or draw dyeing.
It is related to a temporary resist dyeing structure used to prevent staining of dyes on fixed marks or certain areas.Deep dyeing or draw dyeing that prevents staining of the resist dyed areas, has excellent safety and hygiene, and has excellent work efficiency. The purpose of the present invention is to provide a resist dyeing paste for use.

(Prior Art) Conventionally, when dyeing textiles by dip dyeing or draw dyeing, a temporary structure or rubber paste, commonly known as men, is used in order to prevent the dye from sticking to the fixed pattern or certain portions.

Menko is made by boiling glutinous rice in water to form a paste, mixing it with salt, zinc powder, and/or a cationic surfactant, coating it thickly on a mount, and then drying it to form a plate. Rubber glue is made by dissolving rubber in a volatile solvent and mixing it with zinc powder, china clay, etc.

Menko is used by dampening it with water, then punching it out into a certain shape and pasting it on the front and back sides of the resist-dyed part of the fabric, using an adhesive made from Kanbai powder on the adhesive side. In the case of rubber glue, put the rubber glue in a paper tube and apply it directly to the front and back of the resist-dyed part of the fabric, and if necessary, paste pieces of cloth or paper on top of it.

[Problem that the invention seeks to solve]

Traditionally known as menko, because it uses glutinous rice, which is a natural starch, it is hard and brittle, and is prone to cracking due to excessive drying both during manufacturing and after bonding to textiles, making it difficult to avoid contamination during dyeing. Handling is delicate.

By the way, although it depends on the type of dye, dyeing is generally done at 80℃.
It is known that higher temperatures result in better dyeing results. For dyeing, when using menko, which is a traditional temporary resist dye structure, the dyeing temperature is kept as low as possible, from 60 to 80°C, for example, first at 65°C for 15 minutes, then heated to 80°C, and then 1
It requires time-consuming considerations such as dyeing with two-step heating for 5 minutes. The reason for this is that glue made from natural starches such as glutinous rice, which is a component of menko, is easily dissolved and deteriorated when heated in water during dyeing. If dissolution or deterioration of the resist dyeing paste occurs, it will cause staining of the resist dyeing area.

On the other hand, the salt that is mixed into menko for moisturizing purposes has the disadvantage that it dissolves during dyeing, creating so-called salt pools, which are dyed darkly, so it is generally used only for deep black dyeing. ing.

Since rubber glue uses volatile solvents, it poses safety and hygiene problems. In addition, in terms of quality, care must be taken to avoid discoloration of the resist-dyed area due to rubber burning, and volatile solvents are required to remove the rubber paste after dyeing, which is poor in workability and economy.

Therefore, there is a strong demand for a temporary structure for preventing dyeing and staining that prevents staining of the resist-dyed area, is safe and hygienic, and has excellent work efficiency.

c. Means for Solving Problems] The present inventor has proposed that the dyeing contamination of the resist-dyed area can be prevented, and safety and
The present invention was achieved as a result of various studies in order to obtain a resist dyeing plate glue for dip dyeing or draw dyeing that is excellent in hygiene and work efficiency.

That is, the present invention provides one or more components A selected from hydroxypropyl methyl cellulose and methyl cellulose, ovalbumin, polyvinyl alcohol,
Dyeing or collection to which a mixture consisting of one or more components B selected from carboxymethyl cellulose, acrylic esters, and modified starches and one or more components C selected from china clay, zinc chloride, and zinc dust is applied. This is a temporary structure for resist dyeing.

[Effect]

First, the most important point in the present invention is that one or more components A selected from hydroxypropylmethylcellulose and methylcellulose are used as the glue for the temporary resist dye structure, and egg albumin, polyvinyl alcohol, carboxymethylcellulose, The point of using a mixture is to use one or more types of component B selected from acrylic esters and modified starches, and one or more types of component C selected from china clay, zinc chloride, and zinc dust as a dye resist. It is.

In the present invention, component A is used, component B and component C are added and blended, and water is added and kneaded to form a paste-like mixture,
The mixture is applied to a mount and dried to obtain a temporary resist dye structure.

In the present invention, component A is used to form a strong gel with excellent heat retention and adhesive properties at a high temperature of 80°C or higher,
In addition, by using component B to form a paste under heat, the glue containing component C can be made flexible and have increased adhesion to the mount and fabric, and as a result,
It has an excellent resist dyeing effect, and also allows operations such as punching and pasting onto fabrics to be performed easily and accurately.

Next, various conditions for implementing the present invention will be described.

As the mount, waterproof paper is preferred, but cotton cloth, nonwoven paper, etc. can also be used.

The content of component A in the present invention is 10 to 25% by weight; if it is more than 25% by weight, the adhesive surface will become sticky and difficult to handle, and if it is less than 10% by weight, the heat retention effect will be insufficient.

If component B is 10 to 25% by weight, it will be difficult to solidify, and if it is 25% or more by weight, it will be difficult to solidify, and if it is less than 10% by weight, the binding force will be insufficient and the paste will be completely coated on the backing paper.

Component C is contained in an amount of 50 to 80% by weight. If it is more than 80% by weight, the kneaded product will be dry and hard to set. If it is less than 50% by weight, the dye will penetrate through the glue surface and the resisting effect will be insufficient.

We obtained a tentative structure consisting of.

Use Example 1 The resist dyeing board obtained in Example 1 had appropriate humidity, was highly flexible, and when punched into a circle with a diameter of 2 CnA, there were no cracks and the cut edge was smooth. Wet the adhesive side of this punched piece with water, paste it on the front and back sides of 100% silk fabric, and dye three points of medium navy blue, dark navy blue, and black at a dyeing temperature of 95℃. After dyeing for 20 minutes, the colors were dyed, soaked in water at a temperature of 15° C. for 20 minutes, swollen, and then washed with water. As a result, there was no staining and the resist dyeing was good.

Use Example 2 The resist dyeing board obtained in Example 2 had appropriate humidity, was highly flexible, and when punched into a circle with a diameter of 2 cm, there were no cracks and the cut edge was smooth. A 20% solution of hydroxypropyl methylcellulose was applied to the adhesive surface of this punched piece.
Apply a thin layer of glue mixed with a 10% polyvinyl alcohol solution at a ratio of 3:1, paste two pieces of 100% silk white fabric together, and dye the three points: medium navy blue, dark navy blue, and black. After dyeing for 20 minutes at a temperature of 90℃, the color was dyed, soaked in water at a temperature of 10℃ for 20 minutes, swollen, and then washed with water.As a result, there was no dyeing contamination and the result was good (resist dyed). .

Comparative Example 1 The total weight was 100, and 5 parts by weight of 20% hydroxypropyl methylcellulose solution, 5 parts by weight of ovalbumin, 15 parts by weight of china clay, 10 parts by weight of zinc chloride, 10 parts by weight of zinc powder, and 55 parts by weight of water were added. Knead and spread on waterproof paper to a thickness of 2IIll.
Apply to I+ and dry naturally, Component A: 2x4%, Component B
Component C: 12% by weight and component C: 85% by weight were obtained.

As a result of dyeing this temporary structure under the same conditions as in Use Example I, there was obvious dye staining due to poor adhesion to the fabric, and there was no resist dyeing effect.

Comparative Example 2 The total parts by weight was 100, and 2 parts by weight of egg white albumin, 3 parts by weight of carboxyl methyl cellulose, 20 parts by weight of china clay, 10 parts by weight of zinc chloride, 10 parts by weight of zinc powder, and 55 parts by weight of water were kneaded to make waterproof paper. The composition was coated to a thickness of 211,141 mm and dried naturally to obtain a temporary structure consisting of 11% by weight of component B and 89% by weight of component C.

Large and small cracks were observed in the temporary structure, and it was not necessary to carry out a dyeing test (it was not usable as a resist dyeing paste).

〔effect〕

As shown in the above-mentioned examples and usage examples, the resist dyeing board according to the present invention has an appropriate moisture content and is therefore flexible, and as a result, it is difficult to overdry.Therefore, there is no dyeing contamination due to cracks. Also, since it is flexible when used, there is no need to moisten it with water, and it can be punched into a certain shape as it is, which does not require much effort and has good workability.Also, since it does not use salt, it can be punched out into a certain shape. It does not form pools, can be used for staining other than lz color salts, and has the property of forming a strong gel at high dyeing temperatures, so high-temperature staining of 90° C. or higher is possible.

On the other hand, the removal of the resist fabric after dyeing is water-soluble, so
It can be removed by swelling with water and washing with water.

In addition, since the components of this temporary dye resist structure are chemically synthesized, the quality of the product is more consistent than that of natural starch-based products.

As described above, compared to the conventional menko paste and rubber paste, superior effects can be obtained in terms of dye resistance, work efficiency, economy, and health and safety.
