Problems solved by technology

Some commonly used auxiliaries at present are unable to achieve good comprehensive effects in terms of whiteness, wool effect and desizing rate due to poor formulation components or ratio selection, and fabric level dyeing, dyeing rate and printing and dyeing. Poor fastness will affect the quality of subsequent printing and dyeing

Embodiment Construction

[0015] A pretreatment agent for textile printing and dyeing, comprising the following components: a pretreatment aqueous solution, a desizing aid, a complexing agent and an alkali-resistant penetrating agent, wherein the pretreatment aqueous solution includes hydrogen peroxide, biological enzymes and a chelating dispersant WS; the The desizing aid is polyalkylammonium salt, the complexing agent is nitrogen-containing organic polyphosphoric acid, and the alkali-resistant penetrating agent is alkali-resistant nonionic surfactant.

[0016] As a further improvement of the above technical solution, the concentration of the hydrogen peroxide is 2-14g / L; the concentration of the biological enzyme and the chelating dispersant WS is 3-35g / L.

[0017] As a further improvement of the above-mentioned technical scheme, the mass percent of the biological enzyme and the chelating dispersant WS is: 30-70% of the biological enzyme, 30-70% of the chelating dispersant WS, and the chelating disper...

Abstract

The invention relates to a textile printing and dyeing pre-treatment agent. The textile printing and dyeing pre-treatment agent comprises the following components: a pre-treatment aqueous solution, adesizing auxiliary agent, a complexing agent and an alkali-resistant osmotic agent, the pre-treatment aqueous solution comprises hydrogen peroxide, biological enzyme, and a chelating dispersant WS; the desizing auxiliary agent is polyalkyl ammonium salt, the complexing agent is a nitrogen-containing organic polyphosphoric acid, and the alkali-resistant osmotic agent is an alkali-resistant nonionicsurfactant. The energy consumption and material consumption during pre-treatment are reduced, waste water discharge amount is reduced, pollution is reduced, whiteness and a desizing rate of an intermediate product of the textile are increased, and the product quality is effectively guaranteed.

Description

technical field [0001] The invention relates to a pretreatment agent for textile printing and dyeing, which belongs to the field of textile printing and dyeing technology. Background technique [0002] In the process of textile printing and dyeing, it is necessary to pre-treat the fabric to remove impurities on the textile fibers, improve the wettability and whiteness of the textile fibers, and facilitate subsequent dyeing, printing, post-treatment, etc. Processing procedure. The traditional pretreatment process includes multiple steps of desizing, scouring and bleaching. The process is complicated, the process is long, and the material consumption and energy consumption are large, which is not conducive to environmental protection and energy saving production. [0003] At present, in order to simplify the process, the textile printing and dyeing industry tends to adopt a one-step or two-step short-process pretreatment process. The short-process pre-treatment process can s...
