[Brief introduction]

This product has high chelating value and stable chelating ability for heavy metal ions such as calcium ion, magnesium ion and iron ion, especially in the presence of high temperature, strong alkali, oxidant and electrolyte to meet the latest requirements of high efficiency and short process technology in the printing and dyeing industry.

[Functions]

1. Excellent chelating properties for calcium, magnesium and iron ions, chelating ability for iron ions is particularly prominent.

2. Good temperature resistance, alkali resistance, oxidation resistance and electrolyte resistance;

3. Applicable to various processes of textile dyeing and finishing, such as: scouring, bleaching, dyeing, printing, soaping and finishing.

4. It has good dispersing effect on dyes, can keep the dyeing liquid stable, and prevent the condensation of dyes, impurities and dirt.

5. It has a good scale inhibition effect, which can disperse dirt and impurities and prevent it from depositing and sedimenting in equipment. 

[Application range]

1. It can improve the water quality and can be used as a softener with excellent performance when the dosage is small.

2.When used in the pretreatment process, it can effectively prevent the damage of iron ions to fibers during oxygen bleaching under various alkali concentration and high temperature conditions, improve the strength and whiteness of the fabric, and help to stabilize the hydrogen peroxide.
