Technical Field

The invention relates to the technical field of textile printing and dyeing auxiliaries, in particular to an all-in-one scouring agent and a preparation method thereof.

Background

The cotton fabric has strong water absorption, wear resistance, washing resistance, softness, comfort, good warm keeping performance in winter, is breathable and cool in summer, becomes one of the most common children garment materials due to the excellent wearability of the cotton fabric, and is the most popular children garment fabric. Meanwhile, along with the improvement of living standard of people, more and more parents pay attention to the quality and environmental protection of cotton fabrics. In addition, the cotton fabric is generally bright in color, so that the cotton fabric is mainly used for summer wear, leisure wear, underwear, sports wear and the like for children. Due to the characteristics of cotton and the demand of people, the requirement of people on cotton fabrics is higher and higher, meanwhile, the printing and dyeing processing industry is impacted by the factors, is influenced by the factors such as environmental protection, energy conservation, emission reduction and the like, has higher and higher requirements on auxiliaries, and particularly integrates the auxiliary and the low-temperature auxiliary into a whole. Meanwhile, the components of the cotton fabric, such as cotton wax and the like, which influence the performance of the cotton fabric become the biggest factors which plague the industry.

In order to improve the quality of cotton fabrics, particularly ensure the removal rate of cotton wax and sizing agent, ensure the subsequent dyeing property and hydrophilic property, keep the comfort, beauty and environmental protection of wearing, and simultaneously aim at shortening the process flow and reducing the energy consumption of the processing industry.

Disclosure of Invention

an all-in-one scouring agent comprises the following components in percentage by weight:

by adopting the technical scheme, the combination principle of the acrylic acid-hydroxyethyl acrylate-styrene copolymer, the sodium gluconate and the magnesium chloride is that the acrylic acid-hydroxyethyl acrylate-styrene copolymer can effectively chelate metal iron ions, the iron ions are promoters for decomposition of hydrogen peroxide, and the decomposition of the hydrogen peroxide can be effectively controlled by effectively controlling the iron ions.

The cations with desizing and rewetting effects are mainly embodied in the ionic characteristics, because the sizing agent and the wax substances are emulsified by the non-ions and then need to be dispersed in water to be removed, and the cations are just on the surface of the wax substances after the non-ionic emulsification and then dispersed in the water by means of charge elimination, and cannot be mutually aggregated, so that the rewetting is prevented. The combination of the nonionic emulsifier, lauryl glucoside and the plant type environment-friendly modified surfactant can ensure that the alkali resistance, emulsification, refining and wax removal effects of the product are optimal; through the re-optimization and synergistic interaction of the functional components, the process flow can be further shortened, and the effects of energy conservation and emission reduction are achieved.
