Problems solved by technology

The disadvantage is that sodium chlorite is a poisonous chemical. At the same time, the bleaching process using sodium chlorite will produce toxic and corrosive chlorine dioxide gas. big developmental constraints
Although this patented product can be used as a stabilizer in the process of sodium chlorite degumming and bleaching, it can also obtain relatively excellent stabilizing effects, but the formula contains hydrazine sulfate, which is a strong reducing toxic chemical and has carcinogenic properties. Therefore, the patented product has the risk of harming the health of workers during the production and preparation process, which does not meet the environmental protection category

Abstract

The invention relates to an environment-friendly chlorite bleaching stabilizer as well as a preparation method and application thereof. The stabilizer comprises the following components in percentageby mass: 0.4-2% of sodium perborate, 3-8% of ammonium chloride, 3.5-10% of ammonium sulfate, 1.5-4% of borax, 5-8% of polycarboxylic acid, 0.8-1.2% of polyacrylamide, 1-2.1% of sodium gluconate, 1.2-2% of magnesium salt, 0.1-0.3% of preservative and the balance of deionized water. The magnesium salt is sulfate or chloride of magnesium, and the preservative is Proxel LV or Proxel GXL. The stabilizer is used for a linen sodium chlorite degumming bleaching process and has strong pH buffering capacity, the use amount of sodium chlorite is effectively reduced, the escape of chlorine dioxide gas isreduced, the corrosion degree of the equipment is reduced, the bleaching effect is good, the fiber splitting degree is improved, the yarn forming quality and utilization rate of linen staple fibers are improved, and the stabilizer is economical and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing auxiliaries, in particular to an environment-friendly sub-bleach stabilizer and a preparation method thereof. Background technique [0002] Flax fiber is mainly composed of cellulose, hemicellulose, pectin, lignin, wax, and nitrogenous substances. Compared with cotton fiber, flax fiber has irreplaceable advantages such as high strength, high spinnable count, natural and smooth texture, good moisture absorption and breathability, antibacterial health care, etc. It is used in the field of clothing fabrics and has been favored by the high-end market in recent years . However, since the proportion of non-cellulose fibers in the flax fiber is as high as 30%, there are many difficulties in its pretreatment process (especially degumming and bleaching treatment). [0003] At present, the pretreatment process of flax fiber mainly includes "double oxygen bleaching process", "chlorine o...
