Abstract

The invention relates to a direct injection process of disperse dyes, belonging to the technical field of dyeing or printing of textiles. The direct injection process comprises the steps of color paste blending, printing and after-treatment, wherein the color paste is prepared from the following components in percentage by mass: 15%-22% of a toner, 18%-30% of glycerin, 15%-20% of a dispersing agent A, 3%-10% of a dye-resistant agent and the balance of water. The printing comprises the steps of carrying out platemaking by virtue of the color paste according to requirements, and carrying out printing processing on a to-be-processing shell fabric, wherein the printing temperature is 180-210 DEG C, the printing speed is 10-13 m / min, and the feeding rate of the color paste is 30%-45%. The invention is applied to the dyeing or the printing of the textiles and has the advantages of good dyeing effect, high color definition rate, and the like.

Description

technical field [0001] The invention relates to a disperse dye direct injection process, which belongs to the technical field of textile dyeing or printing. Background technique [0002] Existing printing processes mainly include reactive printing and dyeing, acid printing and disperse printing and dyeing, among which disperse dyes include direct injection and printing, but the two methods have higher requirements on color paste and processing technology. At present, there is no mature direct-injection dyeing process of disperse dyes that can be applied to industrial production. [0003] Based on this, this application is made. Contents of the invention [0004] In order to overcome the above-mentioned defects in the existing printing process, the present application provides a disperse dye direct injection process with low cost, high efficiency, good dyeing effect and high stability. [0005] In order to achieve the above object, the technical scheme adopted by the appl...
