Problems solved by technology

[0004] All of the above-mentioned existing technologies provide technical support for no-steam cleaning technology, but the above-mentioned documents do not report on how to realize the simplification of the process flow. Although the report by Cao Wanli et al. reduces the production time by 2 hours compared with the traditional process, it introduces A new cleaning agent was introduced, the input ratio of dyeing auxiliaries was increased, and the cost of printing and dyeing was actually increased, but the shortening of the time did not achieve actual benefits; although the above-mentioned documents have studied the reduction of waste water discharge, they have not Zero discharge of wastewater can be achieved, and no effort has been made on how to reduce toxic substances in wastewater. Therefore, the contribution to energy saving and emission reduction is very limited

Embodiment 1

[0019] Embodiment 1: the dispersion stabilizer that different proportioning forms

[0020] This embodiment is a kind of dispersion stabilizer, and its formula is shown in Table 1.

[0021] The dispersion stabilizer (unit, %) of different proportioning of table 1

[0022]

[0023]

[0024] In this embodiment, water-based polyurethane, acrylic resin and modified PVC resin are used as water-based functional resin components, and the relationship between the three components is proportioned in Table 1, and the water-based silicone oil, diffusing agent , leveling agent, leveling agent, brightening agent, glycerin and water are used as quantitative components, and the pH of the formed dispersion stabilizer is controlled to be 6-7, and the influence of water-based functional resin components on the dispersion stabilizer is tested.

[0025] Apply it to printing or dyeing, the process is pulping→dyeing or printing→steaming, in which, in the pulping process, dye 1-3%, thickener 1...

Embodiment 2

[0030] Embodiment 2: the impact of different proportioning slurry on dyeing

[0031]The dispersion stabilizer corresponding to No. 6 in Table 1 used in this embodiment is used for dyeing. The dispersion stabilizer is composed of: 20% water-based polyurethane, 25% acrylic resin, 15% modified PVC resin, 5% water-based silicone oil, diffusion 5% dyeing agent, 5% leveling agent, 5% leveling agent, 5% brightening agent, 5% glycerin, 10% pure water, apply it to dyeing or printing, the process is: pulping → dyeing or printing →Steaming, wherein, in the slurry preparation process, the composition of the color paste is as shown in Table 2 (the present embodiment takes disperse dyes as a representative to carry out the statement of the scheme).

[0032] Table 2 Color pastes with different compositions (unit, %, water makes up 100%, so it is not listed in Table 2)

Abstract

The invention relates to a dispersion stabilizer and an application thereof, and belongs to the technical field of textile printing and dyeing. The dispersion stabilizer is prepared through high temperature compounding copolymerization of aqueous polyurethane, acrylic resin, modified PVC resin, aqueous silicone oil, a diffusant, a dye leveler, a leveling agent, a brightener, glycerol and pure water, and the pH value of the dispersion stabilizer is not more than 8. The dispersion stabilizer is applied to dyeing or printing, and has the advantages of good color fastness, good wear resistance, fine dyeing, accurate dyeing, no ageing or water washing after dyeing, resource saving and no sewage discharge.

Description

technical field [0001] The invention relates to a dispersion stabilizer and its application, belonging to the technical field of textile printing and dyeing. Background technique [0002] The main process of the traditional disperse dye dyeing and printing process is: pulp preparation→dyeing or printing→baking→reduction stripping→water washing→baking and tentering. Reduction and stripping, resulting in a large amount of printing and dyeing wastewater. [0003] For example, Cao Wanli of Shanghai Desang Fine Chemical Co., Ltd. reported polyester-cotton dispersion / active reduction-free cleaning dyeing (Cao Wanli, Gu Zhian, Lu Zhiyang, Printing and Dyeing, 2010, 36 (22): 23-25), and the high-efficiency special cleaning agent Span.RT is used for disperse / reactive dyeing of polyester-cotton fabrics; Zhejiang Sci-tech University Zhuang Guangqing et al. mentioned the washing-free dyeing of polyester fabrics with disperse dyes (Zhuang Guangqing, Huang Yi, Shao Jianzhong, Printing an...
