The poor colorfastness of reactive dyes is generally related to the incomplete cleaning after printing and dyeing, and consumers are demanding higher and higher colorfastness of reactive dyes. Therefore, the consumption of soaping agent in the whole printing and dyeing auxiliaries is also increasing. It's necessary for the majority of printing and dyeing factories to choose a reliable soaping agent factory because a large number of soaping agents need to be purchased every year. How to effectively reduce the procurement cost of soaping agent, while improving the efficiency of soaping, is an important part of reducing production costs.

1. Low bubbles
A too high foam will lead to a decrease in washing efficiency, which wastes water resources and is not thorough. It will cause stains on the cloth surface.

2.Anti-staining
Whether it is for white printing or soaping of ordinary dyed textiles, good anti-staining is required, otherwise, the dyes are easy to anti-stain the fabric, leading to a decline in fastness.

3. Salt resistance
After dyeing with reactive dyes, soaping solution contains a lot of inorganic salts. If the salt resistance of soaping agent is not enough, there will be uneven soaping power, color, fastness, and other changes.

With the progress of science and technology, especially the continuous efforts of printing and dyeing workers, soaping agent have been developed for several generations, and the advantages and disadvantages have been eliminated. At present, the commonly used soaping agents are low foam soaping agent, active printing soaping agent, acid anti-staining soaping agent and fixing soaping agent.

Low foaming soaping agent: It has excellent functions of removing floating color and anti-staining. It is not easy to hydrolyze and oxidize under hot acid and alkali, and it is resistant to hard water. It can be used for dyeing cotton fabric with reactive dyes and soaping after printing. The main component of this product is dye-philic sparse fiber, which has a high affinity for reactive, direct and VAT dyes, but has no affinity for various fibers. When soaping, the float color dissolves in the soaping agent and is especially easy to wash away. Because of its high dispersibility, the anti-staining effect is excellent. The color of this product decreases after soaping. This product has a high cloud point and a wide temperature range.

Anti-staining soaping agent HTC for reactive printing: It can remove disperse dyes and reactive dye floats adhering to polyester and cotton fibers efficiently in order to improve the fastness of washing, friction, and staining; it is used for disperse/reactive dyes of polyester/cotton fabrics; it is used for one-bath cleaning after stable dyeing, and no reduction cleaning is needed after dyeing polyester, so as to improve production efficiency and shorten process flow. It can effectively solve the problem of unstable cleaning effect, flammable and explosive safety hazards caused by oxidation of powdered insurance during storage; the cleaning process is simple and easy to operate, saving water and electricity, low carbon and environmental protection, greatly reducing COD in dyeing wastewater; it does not contain solvents and is environmentally friendly.


Acidic anti-staining soaping agent: It is suitable for printing and dyeing of wool, nylon, and silk with acid and chrome dye, and for de-floating soaping after dyeing. It has excellent solubilizing property for acid dyes and is a good dye solvent and de-floating soaping agent. It can also be chelated with acid dyes to reduce the affinity of dyes to fibers at low temperatures, thus achieving the anti-fouling function of printed fabrics in white ground. At the same time, it is a kind of low foam material, which will not bring adverse effects on the post-soaping of dyeing and the de-flotation and desizing soaping of printing.

Color fixing soaping agent: It can quickly and efficiently clean the uncolored reactive dyes on cellulose fibers, improve the color fastness to impact, soaping and perspiration, etc. With the high dosage of soaping agent, the soaping residue can be approximately colorless, and the dyes fall off very little when washing with hot water in the back passage. It can reduce soaping, washing times and water volume, and discharge sewage is almost colorless. It can save water, save time, save energy, reduce emissions and protect the environment. Soap detergent itself is soluble and easy to clean, and there is no residue on the fabric. With the high dosage of soap detergent, the residual soap solution can be approximated to colorless, and the dyes fall off very little in the back hot water washing and water washing. The product itself is environmentally friendly, with shallow foot-water after soaping, it can obviously reduce COD and reduce the pressure of wastewater treatment in factories.
