Method of dry transfer printing of synthetic fibrous material with disperse dye and transfer paper

Abstract

A transfer paper which comprises a transfer paper base and a disperse dye ink printed thereon or imparted thereto. The transfer paper is used in a dry transfer printing method in which the transfer paper is pressed against a synthetic fibrous material with heating to thereby transfer the dye (pattern) from the transfer paper to the fibrous material. The transfer paper is characterized in that thetransfer paper base has a releasant layer comprising a synthetic resin soluble in organic solvents and an ink-receiving layer made from a mixture comprising a hydrophilic synthetic resin which softensor melts upon heating, a hydrophilic binder, and various aids, the ink-receiving layer being superposed on the releasant layer. With this transfer paper for dry transfer printing, a highly fine pattern can be printed with excellent reproducibility. Furthermore, the transfer paper enables quick delivery by so-called printing without platemaking. The method of dry transfer plating employs this transfer paper.

Description

technical field [0001] The invention relates to a dry transfer printing and dyeing method of synthetic fiber materials using disperse dyes and transfer paper. Background technique [0002] Conventionally, screen printing, drum printing, rotary screen printing, gravure printing, or transfer printing using these printing methods have been known as methods for firmly and finely drawing patterns with dyes on cloth, and these methods have been used in industry. Yet there are following problems etc. in these plate-making printing methods: [0003] · There are restrictions on the number of colors; [0004] ・Printing using the three-primary-color color separation pattern frame can reflect the multi-color feeling, but it is difficult to adjust the hue and density of the components used in the three-primary-color composition; [0005] · Due to the formation of multiple layers, there is a high possibility that the reproducibility of the printing process will be insufficient.

AI Technical Summary

Problems solved by technology

[0003] · There are restrictions on the number of colors;

[0004] ・Printing using the three-primary-color color separation pattern frame can reflect the multi-color feeling, but it is difficult to adjust the hue and density of the components used in the three-primary-color composition;

[0005] ・Due to the formation of multiple layers, there is a high possibility that the reproducibility of the printing process will be insufficient

[0006] In addition, in small batch production, the following problems have been pointed out: the cost of plate making is high, and the amount of color paste that needs to be prepared during printing processing is greater than the amount required for processing, and the loss and waste of materials increase.

The problem with the direct printing method on cloth is that, as described in Patent Document 1 (paragraphs 0047 to 0051 on page 9 of Japanese Patent Application Laid-Open No. 2005-264021 ) or Patent Document 2 (Japanese Patent Application Publication No. Hei 5-36545 ), etc. , in order to have an anti-permeation effect, pretreatment of fabrics using water-soluble metal salts, polycation compounds, water-soluble polymers, surfactants, and water repellents is indispensable

[0011] (1) Due to the use of disperse dyes with good sublimation properties, bleeding occurs around the pattern and the clarity of the pattern is insufficient

That is, there is a problem that the sharpness and reproducibility of the pattern are insufficient

[0012] (2) Due to the sublimation fixation method, it is difficult to obtain a deep color with a dyeing concentration

[0013] (3) Due to the use of sublimable disperse dyes with low fastness, the thermal stability, sublimation fastness and cleaning fastness are low

[0014] (4) Since the surface is dyed, it is easy to produce chalky spots

[0015] (5) Due to high heat treatment, it will damage the feel of the fiber

Therefore, there is a problem that the absorption of disperse dye ink to transfer paper is poor, and it is difficult to obtain high-density printing.

Furthermore, the transfer paper having a three-layer structure disclosed in Patent Document 6 has problems in terms of engineering and insufficient transfer rate.
