The degree of oxidative damage to cotton fiber during scouring and bleaching not only affects the strength of the fabric, but also affects the dyeing performance of the fiber. It is one of the important reasons for the color and color difference in dyeing, which must be paid attention to.The fundame Read More

1. Uneven cooking results in discoloration.The unevenness of scouring and the uneven removal of impurities on the fabric will cause the moisture absorption rate of the fabric to be different, resulting in colored flowers.measure:① The scouring aids should be injected quantitatively in batches, and t Read More

The fabric bleached with hydrogen peroxide has better whiteness, pure shade, and is not easy to yellow during storage. It is widely used in bleaching cotton fabrics. Oxygen bleaching is more adaptable than chlorine bleaching, but hydrogen peroxide is more expensive than sodium hypochlorite, and oxyg Read More

Eight requirements for hydrogen peroxide stabilizers:1. Excellent adsorption and chelating ability;2. It can withstand different concentrations of alkali agents;3. The strong damage to the fiber is low;4. It has anti-contamination performance;5. It can effectively control the decomposition rate of h Read More

Hydrogen peroxide is the most commonly used oxidizing bleaching agent in the pretreatment bleaching process, whether it is alkaline oxygen two baths, scouring and bleaching one bath, desiccation and bleaching one bath or cold pile bleaching, in order to avoid the ineffectiveness of hydrogen peroxide Read More
