When water is used for scouring, bleaching, dyeing, and/or finishing, it contains excessive amount of impurities and/or heavy metal ions, so it harms the dyed cloth. The DR-100 is a sequestering agent that softens hard water. It is especially efficient for sequencing Fe, Ca, Mg, etc within alkali and for preventing re-adhesion.

The HS DR-100 works to disperse cotton gas and calcium salts. The HS DR-100 also works
effectively to prevent adhesion of sodium silicate and the machinery scale.
The HS DR-100 does not have any harmful effects against metallic dyeing. Also, it is fine to
hydrolyze it in both acid and alkali baths.
The HS DR-100 prevents emulsion, dispersing, and re-attachment of the oligomer and shields
troubles which may be caused by scale and stain when doing Polyester weight loss treatment.
The HS DR-100 prevents pre-hardening, which improves the deduction of the fabrics.
The HS DR-100 prevents dyes from discolorations, improves the fastness when soaping, and
performs greatly to prevent re-adhesion.
