Abstract

PURPOSE:To easily and reproducibly obtain a monotonously printed cloth by printing a cloth with a printing color paste, fixing a part of the dye, removing a part of the dye and dyeing the cloth. CONSTITUTION:A cloth made from natural fiber, semisynthetic fiber, synthetic fiber, etc., is printed with a printing color paste containing a dye (suiting the fiber material), steamed to fix a part of the dye to the fiber, strongly soaped (with a soap containing a reducing agent) to remove 20-70% of the fixed dye and subjected to dyeing treatment to easily and efficiently obtain a monotonously printed cloth having gradated pattern.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a monotone printing cloth whose pattern portion is not clear.

[0002]

2. Description of the Related Art As a so-called printing method for partially dyeing a cloth with a certain pattern, a printing paste containing a dye is printed on the cloth with a screen type or an engraving roller, and then the dye is subjected to a post-treatment such as steaming. To the fabric, or by printing a paste containing a discharge agent on a plain dyed fabric and steam-heat treating this to remove the part white (white discharge), or use a dye that can withstand the discharge agent in advance as the discharge paste. By changing the color of the discharge-printed part to a different color by adding it (coloring discharge-printing), or by printing the dye-proof paste on the fabric with a screen type or engraving roller, etc., then dyeing and printing the dye-proof paste There is a method that does not dye the part (resist prevention method).

As the sharpness and leveling property are improved by improving dyes and the like, these methods have become popular as a dyeing method which is vivid and does not cause color fading, and is now generally used. However, these methods have a problem that it is difficult to obtain a monotone tone whose pattern portion is not clear.

In order to solve these problems, JP-A-49-866090 discloses that an ice piece having a shape and a volume corresponding to the shape and size of a desired pattern is put in a color paste. The ice pieces covered with the color paste, and the ice pieces covered with the color paste are scattered on a pre-expanded fabric and then melted by heating to dilute the color paste. Although a method for producing a monotone printing cloth in which the pattern portion is not clear, which is characterized by being diffused and permeated into the cloth, has been proposed, it has the drawback of not being reproducible.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems in the case of producing a monotone textile printing fabric in which the pattern portion is not clear.

[0006] That is, an object of the present invention is to provide a method for producing a monotone printing cloth whose pattern portion is not clear simply and with good reproducibility.

[0007]

The above-mentioned object is to print a printing paste containing a dye on a cloth, fix at least a part of the dye to a fiber, then drop off a part of the dye, and then dye it. It is achieved by the manufacturing method of the characteristic monotone cloth.

The present invention will be described in detail below.

The cloth used in the present invention includes natural fibers such as cotton, rayon, hemp, silk and wool, semi-synthetic fibers such as acetate and triacetate, synthetic fibers such as polyester, nylon and acrylic, and mixed fibers of various fibers, interwoven fabrics and the like. Applicable to any fiber. Examples of the cloth include woven, knitted, and non-woven fabrics.

The dyes used in the present invention include direct dyes, reactive dyes, and dyes depending on the material of the fiber structure constituting the cloth.
Acid dyes, cationic dyes, disperse dyes and the like can be used. For example, there are direct dyes and acid dyes for silk fibers, direct dyes, vat dyes and reactive dyes for cotton fibers, disperse dyes for polyester fibers, and acid dyes for nylon fibers.

The printing paste used in the present invention may be a paste used for ordinary printing, and it may be selected from starch, modified starch, sodium alginate, methyl cellulose, carboxymethyl cellulose, guar gum, galactomannan, diatomaceous earth, montmorillonite and the like. Mineral-based sizing agents and their blends are preferred.

In addition to the above dye, a hygroscopic agent, a reduction inhibitor, a defoaming agent, an antiseptic agent, a chelating agent, etc. are mixed in the printing paste as required.

As a method of printing a printing paste containing a dye on a cloth, an apparatus such as screen printing, roller printing or rotary printing can be used.

The cloth subjected to such printing is then
It is dried at 0 ° C., then fixed by a method depending on the dye, washed and dried.

Removal of a part of the dye can be performed by a decolorizing agent treatment or strong soaping. For this purpose, washers, winks, jigger, open soapers and the like which are commonly used for dyeing or soaping can be used. The amount of the dye to be removed depends on the amount of the fixed dye, but is usually 10 to 80%, especially 2%.
It is good to drop 0-70%. If the amount to be removed is too small, the contour of the printed pattern remains sharp, which is inconvenient.

Next, dyeing is carried out by a known method. As the dye, a direct dye, a reactive dye, an acid dye, a cationic dye, a disperse dye, etc. are used as a dyeing machine depending on the material of the fiber structure constituting the cloth. Uses a wince, jigger, continuous dyeing machine, etc. according to the material of the fiber structure, and the dye is fixed by a method according to the dye.

[0017]

In the present invention, the printing paste containing the dye is printed on the cloth,
At least a part of the dye is fixed to the fiber, and then a part of the dye is allowed to come off, so that the pattern portion becomes unclear. Then, since the cloth having the unclear pattern portion is dyed next, a monotone printing cloth in which the pattern portion is not clear can be obtained.

[0018]

EXAMPLES The present invention will be described in detail below based on examples.

Example 1 A four-color printing paste containing a dye was prepared according to the formulation shown in Table 1.

[0020]

[Table 1]

The amounts of the above dyes used were as shown in Table 2 below, and printing pastes of four colors A, B, C and D were prepared.

[0022]

[Table 2]

Next, a 100% silk plain woven fabric (warp yarn # 140 twin yarn, which has been scoured by the known method in advance with the above-mentioned four-color printing paste,
Weft No. 140, twin warp, warp 122 / inch, weft 105 /

The product was dyed in a dyeing solution containing 1 g / l of funnel oil at 95 ° C. for 60 minutes and washed with water to obtain the product of Example 1 of the present invention.

The product obtained in Example 1 was a monotone printing product in which the pattern portion was not clear.

[0027]

As described in detail above, according to the method of the present invention,
It is possible to easily and efficiently obtain a monotone textile printing fabric having a pattern that is not clear, has high productivity, and is advantageous in that the manufacturing cost is low. In addition, the obtained fabric has a printed pattern dissolved in the ground color, which makes it a unique product that has never existed before and is extremely useful for casual purposes.
