Abstract

PURPOSE: To provide a resist printed product having irregularities solely in ground dyed parts by using an addition type and a substitution type reactive dyes against a fiber structure consisting of the fiber having polar groups. CONSTITUTION: The method for printing on a fiber structure is to treat a plain weave consisting of a fiber having polar groups such as cotton, etc., through singeing, desizing, scouring and bleaching, pad the treated weave in a dye bath containing a vinyl sulfone-based addition type reactive dye, then squeeze and dry the weave. The plain weave is successively printed by a screen printing method using a printing paste made by blending a monochlorotriazine-based substitution type reactive dye and a sulfite-based resist printing agent, dry and treat the plain weave with steam, print a printing paste containing a gas fading preventing agent in a predetermined pattern by the screen printing method, dip in sodium silicate, wash with hot water, then with water and dry the plain weave.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reactive dye in which only a ground dyeing portion is spotted / a printing method capable of obtaining a dye-resisting fiber structure using a reactive dye.

[0002]

2. Description of the Related Art Conventionally, an addition type reactive dye is applied to a fiber structure containing fibers having a polar group, and then a printing paste containing a substitution type reactive dye and a dye-proofing agent is added to the fiber structure. After printing and steam-heat treatment, it has been practiced to apply an alkaline liquid to this fiber structure to dye the reactive dye, thereby obtaining a reactive dye / reactive dye-proof fiber structure. Therefore, in order to obtain a dye-resisting fiber structure in which only the ground dyeing part is spotted in such a dye-resisting fiber structure, a reactive dye /
Background Art It has been practiced to carry out alkaline discharge dyeing on a dye-resisting fiber structure with a reactive dye to half discharge the ground dyed part.

[0003]

However, the method of subjecting the ground dyeing part to half discharge printing by subjecting the dye-removing fiber structure made of the reactive dye / reactive dye to alkali discharge dyeing is a method of half discharge dyeing the ground dyeing part. The difference was subtle, and there was a problem that it was unsuitable for designs that required contrast.

The present invention has been made in order to solve the above problems, and in a reactive dye / reactive dye-resisting fiber structure, a ground structure is clearly spotted. An object is to provide a simple and efficient printing method for obtaining a product.

[0005]

Means for Solving the Problems The above-mentioned object is to provide a fibrous structure containing fibers having a polar group with an addition type reactive dye, and then partially add a substitution type reactive dye and a sulfite-based dye. It is achieved by a method for printing a fibrous structure, which comprises applying a gas discoloration preventive agent partially after applying the same to the above, and then applying an alkali.

The present invention will be described in detail below.

Examples of the fiber having a polar group used in the present invention include cellulosic fibers such as cotton and rayon, and fibers having a polar group that reacts with a reactive dye such as wool and silk. Examples of the fibrous structure include woven fabrics, knitted fabrics, and non-woven fabrics made of fibers having such polar groups.

Examples of the addition-type reactive dye used in the present invention include vinylsulfone-based reactive dyes having a high reactivity for a two-phase method, and specifically, Remazole of Hoechst and Mitsubishi Chemical. Examples include Diamira and Sumitomo Chemical's Sumifix. Then, in addition to the addition-type reactive dye, if necessary, a pH adjusting agent such as acetic acid, sodium hexamethanoate, and primary sodium phosphate, and a reduction inhibitor for sodium metabenthene sulfonate are used. Such an addition type reactive dye is applied to the fiber structure by a put dry method, a spray dry method or the like.

The substitutional reactive dyes used in the present invention are those used as a color-imparting color, and are usually reactive dyes for one-phase method, such as monochlorotriazine, which have low reactivity. ICI Procion H, CIB
Examples include Cibacron from A-GEIGY, and Kayashion from Nippon Kayaku. Further, as the sulfite-based stain-proofing agent, the reactive group of the addition-type reactive dye applied to the fiber structure is blocked to eliminate the reactivity. Here, the sulfite-based stain-proofing agent composed of an aldehyde and a sulfite salt is used. To use.
Specifically, BASF's Reactive Resist
Ting Agent, Super Resist NP, GCR-07, GCR-18 manufactured by Nippon Senka Co., Ltd., Sunresist RD-90 manufactured by Nichika Chemical Co., Ltd., and the like. Then, in addition to the substitutional reactive dye and the sulfite-based dye-proofing agent, if necessary, sodium carbonate, sodium bicarbonate, sodium hydroxide,
Alkali such as disodium phosphate, trisodium phosphate, etc., sodium hexametaphosphate, primary sodium phosphate such as p
An H regulator, a reduction inhibitor such as sodium metabenzenesulfonate, and a hydrotrope such as Pt are used. Such substitutional reactive dyes and sulfite-based dyes are screen-printing methods, roller-printing methods, rotary-printing methods for fiber structures,
Partially applied by an inkjet printing method or the like.

Then, a steam heat treatment is performed at a temperature of 100 to 110 ° C. for about 2 to 10 minutes using a high temperature steamer (HTS) or the like which uses atmospheric pressure superheated steam.

The gas discoloration inhibitor used in the present invention includes:
Is intended to Fukushoku those addition type reactive dyes by SO _X gas exiting when steamed sulfite-based antifoulant agent is faded, and specific examples thereof include a gas guard FX etc. Meisei Chemical Company. Such a gas discoloration inhibitor is partially applied to the fiber structure by a screen printing method, a roller printing method, a rotary printing method, or an inkjet printing method. In addition, when partially applied, it is preferable to apply it in a patchy manner because the effect becomes clearer.

The alkali used in the present invention is one that causes a reactive dye to develop a color, and specific examples thereof include sodium silicate and the like. Such an alkali is applied to the fiber structure by a padding method or a dipping method. After applying, washing with hot water, washing with water, and drying are performed.

[0013]

When the sulfurous acid type dye resisting agent is steam-heated, the SO _x gas causes the addition type reactive dye to fade. However, when the gas discoloration inhibitor is partially applied and alkali is applied, the part to which the gas discoloration inhibitor is applied is restored, while the part to which the gas discoloration inhibitor is not applied is recovered. Since there is no color, spots having a clear density difference will occur in the ground dyed part.

The gas discoloration inhibitor was partially applied, and then the alkali was applied. For this reason, the part to which the gas fading preventive agent is applied becomes darker due to the addition type reactive dye returning color, and the part to which the gas fading preventive agent is not applied becomes lighter because the addition type reactive dye does not return. The part becomes a clear spot. As described above, the fiber structure subjected to the printing method according to the present invention has clear spots on the ground dyed portion, and is therefore useful for casual uses such as shirts and blouses. Further, the method of the present invention can be carried out without using a special device, and its usefulness is obvious.
