Problems solved by technology

[0004] However, when using the fine particle dye in the dispersed state, in order to fully diffuse the fine particle dye in synthetic fibers such as polyester and nylon as the dyeing object, a high temperature is required, and the color unevenness of the dyed product occurs due to the sedimentation of the fine particle dye. topic
In addition, when used as an ink for inkjet printing and dyeing, it is necessary to adjust the type and amount of the dispersant to achieve a low viscosity, so it may not be able to obtain sufficient stability and reduce the storage stability.

Embodiment 1

[0138] In Example 1 and Example 2, although the disperse dye could not be completely dissolved, the dyeing density (Db value) obtained by steaming at 100° C. was 0.5. In contrast, in Comparative Examples 1 to 5, although the disperse dye was completely dissolved, the dyeing density (Db value) obtained by steaming at 100° C. was 0.3 or 0.4. The reason for such a difference in dyeing density is not clear, but it is considered to be due to the structural characteristics of solvent A and solvent B. As above, in Example 1 and Example 2, although the concentration of the disperse dye actually becomes lower compared with Comparative Examples 1 to 5 by filter filtration, the obtained Db value becomes higher, so it can be considered that at least The effect of solvent A or solvent B is exerted. In addition, in Examples 4 to 16, Db values ​​higher than those in Examples 1 to 2 were obtained by using the ink composition in which the disperse dye was completely dissolved in solvent A or ...

Abstract

An ink composition for ink jet textile printing comprises a disperse dye and a solvent represented by the following Formula (1): (in Formula (1), R 1 denotes an alkyl group having 1 to 4 carbon atoms).

Description

technical field [0001] The invention relates to an ink composition for inkjet printing and dyeing and an inkjet printing and dyeing method. Background technique [0002] The so-called disperse dyes refer to dyes used for dyeing hydrophobic synthetic fibers such as polyester, nylon, and acetate. Since disperse dyes do not contain a hydrophilic group such as a sulfonic acid group or a carboxyl group, they are water insoluble or poorly soluble in water. Therefore, disperse dyes are used as fine particles dispersed in an aqueous medium. [0003] Conventionally, techniques for dispersing disperse dyes as fine particles in an aqueous medium are widely known. As a representative dispersant for dispersing disperse dyes in an aqueous medium, for example, formalin condensates of naphthalenesulfonic acid, ligninsulfonic acid, etc., can be cited in addition to those described in Patent Documents 1 to 5. surfactants, etc. [0004] However, when using the fine particle dye in the disp...
