Abstract

The invention discloses an acid scouring agent and a preparation method thereof. The acid scouring agent comprises a multivariate acidic copolymer, polyvinyl pyrrolidone PVP and sodium gluconate. The scouring agent does not contain phosphorus, alkylphenol ethoxylates and harmful solvents and is degradable; and at the same time, the scouring agent has the characteristics of a little foam, high chelation value and high alkali neutralizing capacity. The scouring agent can be used for scouring cellulose fibers after dyeing, can simplify the traditional process and contributes to energy conservation and emission reduction.

Description

technical field [0001] The invention relates to a reagent for the textile dyeing and finishing industry and a preparation method thereof, in particular to a reagent for soaping after dyeing cellulose fibers and a preparation method thereof. Background technique [0002] The printing and dyeing industry is an important component of the textile industry, and it is also an industry with high energy consumption and large sewage discharge. In the printing and dyeing industry to carry out energy saving and emission reduction work, in addition to research and development of high-efficiency, water-saving, and energy-saving equipment, and the development and promotion of practical new technologies for energy-saving and water-saving, the use of high-efficiency, environmental protection, water-saving, and energy-saving dyeing and chemical materials is the most popular at this stage. It is an effective method with less investment and quick results. [0003] Reactive dyes are generally ...
