Softener Properties
- Jan 11, 2019 -

The softener can be used as a synergist for pre-dyeing treatment, because the heavy metal ions in the water will combine with the detergent molecules to form an insoluble metal salt, thereby reducing the washing ability of the detergent. These insoluble metal salts are also deposited on the textile, causing the fabric to become hard and hairy, affecting the quality of the pretreatment. Softeners have a strong chelating ability for heavy metal ions, which can block these metal ions so that heavy metal ions do not adversely affect the detergent and improve the quality of the pretreatment.
