Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for resist dyeing a fibrous structure consisting of cellulose, fiber and protein, and one fiber.0 (Prior Art) Conventionally, Regarding ground dyeing for discharge printing of cellulose fibers and protein fibers, the exhaust dyeing method using a Winx dyeing machine or a jet dyeing machine is usually carried out, and the padding method is not often carried out. This is because it is difficult to uniformly dye cellulose fibers and protein fibers using the padding method.

In addition, when discharging a dyed product ground-dyed by the exhaustion method, the discharge is difficult to achieve if a reactive dye is used to dye the product, so a dyeing method using a threne dye has been implemented.

However, this method requires complicated steps such as controlling the dye liquor, and it is difficult to obtain distinct colors between groups.

(Problems to be Solved by the Invention) An object of the present invention is to provide a method for resist dyeing a fiber structure made of cellulose fibers and protein fibers, which has excellent color development.

Another object of the present invention is to provide a method for carrying out such resist dyeing by a combination of ground dyeing using a padding method with excellent level dyeing properties and a simple printing method.

(Means for Solving the Problems) The method of the present invention involves applying a neutral to acidic dye solution containing a vinyl sulfone type reactive dye to a fiber structure made of cellulose fibers and protein fibers. , left to stand for a predetermined time, then printed with a printing paste containing a monochlorotriazine type reactive dye, an alkaline agent, and a resist dye for vinylsulfone type reactive dyes, dried and steamed, and then further applied with an alkaline solution. It is characterized by steam treatment.

Examples of cellulose fibers used in the present invention include cotton, recycled fibers, hemp, and the like.

In addition, examples of protein-based fibers include wool, silk, and the like. The mixing ratio of cellulose fiber and protein fiber is usually 55 to 90% by weight of cellulose fiber, preferably 70 to 90% by weight.
85% by weight, and 10-45% by weight of protein-based fibers, preferably 15-30% by weight. The mixture of the two may be blended spinning, twisted twisting, mixed weaving, or mixed knitting, but blended spinning is particularly preferred. As the fiber structure, woven fabrics are particularly preferred.

Conventional vinyl sulfone type reactive dyes are used, such as Remazol dye manufactured by Hoechst, Sumifix manufactured by Sumitomo Chemical, Selmazole manufactured by Mitsui Toatsu, and Diamira manufactured by Mitsubishi Kasei. The concentration of the dye solution is not particularly limited and may be appropriately determined depending on the type of dye, color, etc. The pH of the dye liquor must be adjusted to be neutral or acidic, and T)H is 8 or less, preferably 7 or less, more preferably 6 or less, particularly preferably 5 or less. The pH is usually adjusted using acetic acid, sodium hexametaphosphate, dibasic sodium phosphate, or the like. The temperature of the dye liquor is not particularly limited and may be a normal temperature, generally 20 to 30°C.

The dye solution may be applied by any of the padding method, roller method, spray method, etc., but the padding method is particularly preferred.

The fibrous structure to which the dye liquor has been applied is once wound up and left to stand, usually at 10 to 60°C. The standing time varies depending on the temperature, but is usually 10 to 50 hours. Preferably 20-80℃
Leave it for 20 to 30 hours.

During this time, the protein fibers are dyed with a vinyl sulfone type reactive dye.

After standing, the fiber structure is usually heated to 80°C or higher, preferably 10°C.
Dry at 0-120°C.

After drying, a printing paste consisting of a monochlorotriazine type reactive dye, an alkaline effecting agent, a vinylsulfone type reactive dye resisting agent, and a sizing agent is printed and dried in a conventional manner,
Next, a steaming treatment is performed.

Common monochlorotriazine dyes can be used in the present invention, such as Ciba-Geigy's (77 Cibacron dye, 101 Prodione dye, etc.).

The resist dye Ji is for vinyl sulfone-type reactive dyes, and organic sulfonate-based chemicals are used, such as Kaisei Kagaku Co.'s Registol HW8 and Hayashi Kagaku Co., Ltd.'s Unistone Bon R-50. .

These dyes and resist dyes are added with soda ash, an alkaline agent such as heavy Δ, and urea to form a printing paste together with a sizing agent such as sodium alginate or CMC for printing. Stamping, drying,
The steaming treatment may be performed by a method commonly used in textile printing, for example, printing is performed using a screen printing machine, drying is performed, and then steaming treatment is performed at 100° C. for 10 minutes using a kneer.

Through this process, the vinyl sulfone type reactive dye for ground dyeing in the printed area is resist-dyed, and at the same time, the monochlorotriazine type reactive dye is colored.
After application of 3 degrees Baume's water glass solution, usually at least 1
Steaming is carried out at a temperature of 00°C, preferably 120-130°C. The shorter the steaming treatment time is, the more preferable it is, and it is about 1 minute at most. This steam heat treatment is used to color the fabric with a vinyl sulfone type reactive dye, which is then washed to complete the printing process.

(Effects of the Invention) 1. The method of the present invention uses an ordinary continuous fabric dyeing machine to dye an a-fiber structure made of cellulose fibers and protein fibers with excellent level dyeing properties and deep dyeing. In addition to providing dyeing, this method is a printing method that requires low temperature dyeing and short heating time, so the fiber structures obtained by this method have an extremely good texture and are printed products with extremely low strength loss.
