Abstract

The invention relates to a multi-color roller gravure printing production method of a textile dye. According to the traditional printing method, more floating colors exist in the washing process, and the excessive wastewater discharge is easily caused. The invention comprises the following steps that: (1) pre-treatment working solutions are selected according to textiles of different types of fibers; (2) the pre-treatment working solutions of different concentrations are padded under the conditions that the immersion time is 5-30 seconds, the expression is between 50% and 100% and the speed is 10 to 40m / min, and are dried; (3) a special dye ink for gravure printing is selected; (4) through an improved multi-color roller gravure printing machine with adjustable printing thickness, lengthened width, enhanced drying and the like, the special dye ink is printed to the textile which is padded with the pre-treatment working solutions and is dried at a speed of 10-40 m / min and is dried; (5) the printed textile enters steaming equipment for steaming fixation; and (6) after fixation, the printed textile is subjected to washing, drying and other treatment processes to complete the entire printing production process of the textile.

Description

technical field

[0001] The invention relates to a production method for multi-color roller gravure printing of textile dyes. Background technique

[0002] The methods of printing textiles with dyes are mainly divided into two categories in the printing and dyeing industry. One category is dye flat screen printing or rotary screen printing with up to a dozen sets of colors; the other category is dye transfer printing.

[0003] Dye flat screen printing or rotary screen printing is a traditional printing method, which has the advantages of short process flow and low production and processing costs. There are many floating colors in the process, and they enter the washing solution in large quantities during washing, resulting in excessive wastewater discharge. At the same time, these unfixed dyes may even stain the white ground of printed textiles, causing quality problems in printed textile products. and other shortcomings.

[0004] Dye transfer printing is a novel printing m...
