The present invention relates to a dye composition of a water-insoluble or slightly water-soluble dye, and is used for printing or thermosol dyeing polyester fibers, acetate fibers, etc., or blended fibers of polyester fibers, acetate fibers, etc. with natural fibers such as cellulose fibers. The present invention relates to a dye composition of a water-insoluble or slightly water-soluble dye suitable for dyeing. Generally, when printing synthetic fibers such as polyester fibers or blended fibers of synthetic fibers and natural fibers such as cellulose fibers, the disperse dye is usually used as a base paste for printing consisting of starch or a water-soluble polymer substance such as carboxymethyl cellulose. A color paste for printing is prepared by mixing with the polyester fiber, and after printing this on the polyester fiber, it is fixed by high temperature and high pressure steaming, high temperature and normal pressure steaming, or dry heat fixing. A method has been adopted in which the dye is fixed onto the fiber. Among these fixing methods, the high temperature normal pressure steaming fixing method and the dry heat fixing method in particular allow continuous printing and are currently being widely used from the viewpoint of streamlining the process, but there is a limit to the fixation rate of the dye and the surface color density is limited. It has the disadvantage that it is not sufficient and it is difficult to develop vivid colors. Conventionally, in order to improve this drawback, a method has been known in which a so-called carrier, which is a compound capable of swelling a polyester such as a chlorobenzene type or a methylnaphthalene type, is added to a color paste for printing. This method promotes the diffusion of disperse dyes into the fibers, improving the fixation rate of the dyes and increasing the surface color density. There is a side. Furthermore, a method is known in which a printing process is carried out by adding a so-called deep dyeing agent, which is a compound having a surfactant ability that can speed up the monomolecularization of disperse dyes, to a color paste for printing. This method promotes the diffusion of disperse dyes within the paste, improving the dye fixation rate and increasing the surface concentration. However, on the other hand, specks occur due to secondary aggregation of dye particles, and printing operability is affected by gauze stains. There are problems such as a decrease in the sharpness of the image, a decrease in the sharpness of the edges of the image, and scratch stains due to a decrease in coating strength. In addition, when polyester fibers or blended products of polyester fibers and cellulose fibers are thermosol dyed, generally a disperse dye is mixed with an aqueous solution of a water-soluble polymer substance such as sodium alginate to prepare a pad bath, and the fibers are dyed in a pad bath. Methods of fixing dyes on fibers include methods such as immersing them in a bath, squeezing them out, pre-drying them, and fixing them with dry heat, but the fixation rate of the dyes is low and it is especially difficult to dye deep colors. be. In such cases, a large amount of dye is used to dye the dye in deep colors, but there is a drawback that a large amount of unfixed dye flows out into waste water, causing pollution problems. In addition, large amounts of water-soluble polymeric substances such as sodium alginate, so-called anti-migration agents, are added to improve level dyeing, but because of their poor compatibility with dyes, secondary aggregation of dye particles may occur. Occasionally, speck occurs. The present inventors fully grasped the above-mentioned situation, and in particular, the high temperature normal pressure steam fixing method and the dry heat fixing method for textile printing.
Furthermore, even when applied to thermosol dyeing, the dye has a high dye fixation rate and a very good surface coloring density, and is a water-insoluble or poorly water-soluble dye for textile printing and thermosol dyeing that has improved the current drawbacks mentioned above. As a result of intensive studies aimed at obtaining a composition, we found that a dye composition containing a polymer of vinyl pyrrolidone and/or a copolymer of vinyl pyrrolidone and an unsaturated organic compound is used. The present invention was completed based on the finding that printing and thermosol dyeing of fibers such as polyester can be carried out extremely well. That is, the gist of the present invention is to provide a water-dispersed dye composition containing a water-insoluble or slightly water-soluble dye and a water-based solvent, in which a polymer of vinylpyrrolidone and/or a polymer of vinylpyrrolidone and an unsaturated organic compound is used. A dye composition characterized by containing a copolymer with To explain the present invention in detail, the water-insoluble or poorly water-soluble dye used in the present invention is a commonly used water-insoluble or poorly water-soluble nonionic dye such as anthraquinone, azo, or quinophthalone. can be used. In addition, well-known materials such as the base paste for textile printing or the aid for thermosol dyeing may be used. As mentioned above, the dye composition of the present invention contains as an essential component one or a mixture of two or more of a polymer of vinyl pyrrolidone and a copolymer of vinyl pyrrolidone and an unsaturated organic substance. Or the copolymer is required to be very compatible in the dye composition. Examples of vinylpyrrolidone polymers and copolymers of vinylpyrrolidone and unsaturated organic compounds include the following general formula: (In the formula, n represents an integer from 10 to 4000.) (In the formula, n and m represent integers from 10 to 4000, and V
(1) Carboxylic acid vinyl ester compounds such as vinyl acetate and monochlorovinyl acetate, (2) Vinyl carboxylic acid compounds such as metal salts or ammonium salts such as vinyl acetate ethyl acrylate and maleic acid, (3) Vinylidene chloride, etc. halogenated vinyl compounds, (4) α-olefins such as ethylene and propylene, (5) vinyl-substituted alicyclic compounds such as vinylcyclohexane, (6) vinyl ether compounds such as butyl vinyl ether, (7) methyl vinyl ketone, etc. vinyl ketone compounds, (8) vinyl-substituted aromatic compounds such as styrene, divinylbenzene, vinylbenzyl chloride, vinyl anthraquinone, and (9) vinyl group-containing compounds such as vinyldichloromethylsilane or metal salts or ammonium salts of vinylsulfonic acid. This refers to a divalent group derived from an unsaturated organic compound having an ethylenically unsaturated bond such as. ) The polymers or copolymers represented by the above general formula include those whose 25% aqueous solution has a viscosity of 50 to 1000 cps/25°C, and 1000 to 10000 cps/25°C. things and
10,000 cps/25°C or more can be obtained by polymerization or copolymerization as low viscosity products, medium viscosity products, and high viscosity products, respectively. In obtaining the dye composition of the present invention, polymers of vinyl pyrrolidone and/or copolymers of vinyl pyrrolidone and organic unsaturated compounds of various viscosities can be used, but generally have a low to medium viscosity. best results are obtained using the following products. These polymers and copolymers are usually blended singly or in an amount of 0.001 to 5.0 times, preferably 0.01 to 1.0 times the weight of the water-insoluble or poorly water-soluble dye base material. In addition to the above-mentioned polymer and/or copolymer, the composition of the present invention further contains water and, if necessary, an organic solvent, a dispersant, an emulsifier, an emulsion stabilizer, a viscosity modifier, an anti-drying agent, etc. Good too. To prepare the dye composition of the present invention, the above-mentioned water-insoluble or poorly water-soluble dye raw material is usually finely ground, and then water, a polymer of vinylpyrrolidone and/or
Alternatively, a paste is prepared by adding a copolymer of vinyl pyrrolidone and an unsaturated organic compound, a dispersant, and an emulsifier, and if necessary, a dispersant, viscosity modifier, anti-drying agent, etc. are added, and then, for example, sand With a grinder or paint conditioner, etc.
A pasty dye composition of the water-insoluble or poorly water-soluble dye of the present invention is prepared by pulverizing and dispersing the dye particles with a size of 0.01 to 10 μm, preferably 0.01 to 1 μm. A colored paste for textile printing can be obtained by adding the dye composition of the present invention to a base printing paste made of a conventional water-soluble polymer substance or an emulsion base paste made of an emulsified mineral turpentine. Further, a dye pad bath can be obtained by adding it to a pad bath consisting of a conventional migration inhibitor such as sodium alginate. Examples of fibers that can be printed or thermosol dyed using the dye composition of the present invention include polyester fibers such as polyethylene terephthalate fibers and polyoxybenzoate fibers, and acetate fibers such as diacetate fibers and triacetate fibers. Examples include hydrophobic synthetic or semi-synthetic fibers, as well as blended fibers of these synthetic fibers and natural fibers such as cellulose fibers, and the effects are particularly remarkable when applied to polyester fibers. The dye composition of the present invention is extremely useful in terms of economy and operability since it is possible to produce a product with high dye concentration, and it can be stored in a stable dispersion state for a long period of time. The compositions of the invention are stable for long periods of time when printing pastes or thermosol pad baths are prepared. When these printing pastes or thermosol pad baths are used to print or thermosol dye polyester fibers or blended fibers of polyester fibers and cellulose fibers, they show an extremely high dye fixation rate and a low surface color density. It is characterized by high EXAMPLES Hereinafter, the present invention will be explained in more detail with reference to Examples, but the present invention is not limited to the following Examples unless it exceeds the gist thereof. In addition, "parts" in the examples indicate "parts by weight."
