Comparison of the bleaching effect of sodium chlorite and sodium hypochlorite

Sodium chlorite is a fine bleaching agent, in the textile industry in a wide range of adaptability, and fiber strength damage is small, to the effect of good, white is also relatively good, but the disadvantage is that the equipment material requirements. Sodium chlorite main bleaching composition for chlorine dioxide, dissolved lignin and molecular weight lower pectin, but not oxidized cellulose hydroxyl, and only oxidized cellulose molecular bonds at the end of the aldehyde group and did not cause cellulose molecular bond breaking, which can maintain fiber high strength.

Sodium hypochlorite is an excellent bleaching agent, deodorant, widely used in papermaking, wastewater treatment, textile and other industries. Due to the sodium hypochlorite itself is easy to decompose, coupled with industrial sodium hypochlorite solution in the presence of metal ions and impurity exacerbated the instability, to the sodium hypochlorite production, storage, transportation and use caused many difficulties, so as to reduce the effective chlorine content, the sterilization, the elimination of poison and bleaching effect to sell at a discount greatly.
