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

Abstract

The invention relates to a spinning and dyeing pretreatment auxiliary agent, which is prepared by adopting the following raw material components: 30 to 50 parts by weight of desizing agent, 5 to 20 parts by weight of alkali-resisting penetrant, and 4 to 10 parts by weight of complexing agent; the desizing agent is multi-alkyl amine salt; the alkali-resisting penetrant is an alkali-resisting nonionic surfactant; the complexing agent is hydroxy carboxylate. Further, the adopted raw material components also include 1 to 10 parts by weight of hydrogen peroxide stabilizer; the hydrogen peroxide stabilizer is organic phosphonate. The spinning and dyeing pretreatment auxiliary agent can be obtained through the preparation of successively mixing the raw material components, and the spinning and dyeing pretreatment auxiliary agent can be applied to a cold-batch method or open-width scouring-bleaching method spinning and dyeing pretreatment process. The spinning and dyeing pretreatment auxiliary agent can shorten the flow of the conventional spinning and dyeing pretreatment process, can reduce the energy consumption and material consumption in the pretreatment process, and can reduce the effluent volume; an obtained intermediate product of textile fabrics has good whiteness, capillary effect and desizing percentage.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing technology, and in particular relates to a pretreatment auxiliary agent for textile printing and dyeing, a preparation method and application thereof. 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 ...
