[Product introduction]

The product has high chelating value and stable chelating ability to calcium ion, magnesium ion, iron ion and other heavy metal ions, especially in the presence of high temperature, strong alkali, oxidant and electrolyte, which can still play a stable chelating effect, and meet the latest requirements of high efficiency and short process technology in the printing and dyeing industry.

[Features and advantages]

1. Suitable for all processes of textile dyeing and finishing, such as scouring, bleaching, dyeing, printing, soaping and finishing. The chelating value of calcium, magnesium and iron ions is significantly higher than that of similar products on the market, especially for iron ions.            
2. It has good stability in high temperature, alkali, oxidation and electrolyte, especially the chelating ability of iron ion increases with the increase of temperature and alkali concentration.            
3. It has good dispersing effect on dyes, can keep the stability of dyeing solution, and prevent the agglomeration of dyes, impurities and dirt.           
4. It has good scale inhibition effect, which can disperse dirt and impurities and prevent them from depositing and depositing in the equipment.  

[Application range]

1. When it is used in the scouring process of pure cotton and its blended fabrics, it is not only suitable for the traditional process, but also can meet the current high standard requirements of cold pad batch pretreatment, desizing and boiling one bath pretreatment, and one-step pretreatment process of high-efficiency desizing, boiling and bleaching.            
2. It is suitable for various pretreatment, dyeing and soaping of knitted fabrics, yarns and woven fabrics.           
3. It can effectively prevent the damage of iron ions on the fiber during oxygen bleaching, improve the strength and whiteness of the fabric, and stabilize the hydrogen peroxide.            
4. It is helpful to disperse and permeate the dyes, prevent the dyes from agglomerating into color spots or spots, make the dyed fabric or yarn have uniform color, pure and bright color, and improve the quality of dyed products.            
5. In soaping process, it can remove the floating color of dye, prevent the dye from being contaminated again, and improve the color fastness of the product. It has obvious synergistic effect when used in the same bath with other anionic and nonionic auxiliaries.            
6. It can improve water quality. When the dosage is small, it can be used as softener with excellent performance.
