Product features:

1. It has strong chelation and dispersing ability for metal ions such as Ca2+, Mg2+, Cu2+ and Fe2+. Excellent dispersion of solid particles and oligomer gels;

2. It is used for dyeing and finishing treatment process, which can obviously improve the scouring effect;

3. In the processes of desizing, scouring, bleaching and dyeing, the effect of metal ions such as Ca2+, Mg2+, Cu2+ and Fe2+ in water on product quality can be reduced;

4. It has a protective effect on the decomposition of H2O2 and has a protective effect on fibers;

5. Low inorganic salt content, suitable for compounding various additives.
