Embodiment 1

[0023] This embodiment discloses a water-free printing method for blue disperse dyes, which specifically includes the following steps:

[0024] S1. Configure disperse dye less washing printing paste, add 4.0g of acrylic thickener to 83.3g of water, stir well at 800 rpm to form a paste, add 5.0g of water-based polyurethane emulsion, 0.2g of closed type Isocyanate crosslinking agent, 1.0g methyl silicone softener, 2.0g urea, 0.5g castor oil, after stirring at 800 rpm, add 4g of blue disperse dye, stir at 800 rpm to make a dispersion Dye less washing printing paste;

[0025] S2, printing, using the method of flat screen, rotary screen or manual printing to print the disperse dyes prepared in S1 on the gray cloth surface to obtain a printed cloth sample;

[0026] S3, drying, placing the calico sample obtained in S2 at 100-120° C. for 3-5 minutes;

[0027] S4. High-temperature color development. The printed fabric sample dried in S3 is developed at a high temperature of 180-200° ...

Abstract

The invention relates to the technical field of printing treatment, and particularly discloses a washing-free or less-washing printing method. The washing-free or less-washing printing method comprises the following steps that disperse dye less-washing printing color paste is prepared from the following components in percentage by weight: 1-10% of disperse dye, 2-5% of a thickening agent, 0.5-2% of a softening agent, 2-5% of polymer emulsion, 0.1-0.5% of a color fixing crosslinking agent, 2-8% of a deepening agent, 0.3-3% of vegetable oil and the balance of deionized water; the prepared disperse dye less-water printing color paste is printed on the surface of a gray fabric by adopting a flat screen, rotary screen or manual printing method; and drying and high-temperature color developmentare conducted to obtain the printed fabric. The defects in the prior art are overcome, the printing process is simple, the dye consumption is reduced, water washing is not needed or only simple one-step normal-temperature water washing is needed, pollution is small, and the application prospect is wide.

Description

technical field [0001] The invention relates to the technical field of printing treatment, in particular to a printing method with no washing or little washing. Background technique [0002] Printed products in the textile printing and dyeing industry are more dominant than dyed products. Printed fabrics are quite popular because of their novel style, color and pattern following the new international and domestic trends, and they have a great advantage in the textile market transactions. However, the traditional dye printing process has the three high phenomena of high energy consumption, high water consumption and great impact on the environment. In recent years, the environmental problems caused by industrial production have attracted the attention of people and the government, and the voice of the society to strengthen environmental protection supervision of polluting enterprises is increasing. Therefore, green printing and dyeing is the development direction of the prin...
