Special, environmental friendly chelating agent for the pre-treatment of cotton in alkaline scouring, bleaching and bioscouring processes.
Natural cellulosic fibers may contain high concentrations of metal ions. These may occur as salts, silicate complexes or be bonded to natural impurities. Metal ions interfere with pre-treatment. Heavy metal ions act as catalysts and can cause damage during bleaching. Ions bonded to pectins and hemi-cellulose are not easy to remove. Fatty acids may form insoluble saponification products with calcium and impair the absorbency of the goods.
PLEXENE® PREP 01 forms very stable complexes with interfering metal ions. These are soluble in water and can therefore be removed easily. Pre-treatment with PLEXENE® PREP 01 ensures very uniform bleaching and thus high whiteness. Goods pre-treated with this product also have excellent absorbency.
