One-dose one-bath low-temperature type pre-treatment compound preparation

Abstract

The invention relates to a one-dose one-bath low-temperature type pre-treatment compound preparation which comprises the following components in mass percentage: 35.3-52.1% of hydrogen peroxide additive, 11.1-23.1% of peroxysulphate, 2.7-8.0% of sodium hydroxide, 5.5-15.4% of multifunctional additives, 11.8-28.6% of metasilicic acid alkali metal and 2.7-8.0% of surface active agent. According to the compound preparation, multiple functions, such as a refining function, a bleaching function, a permeating function and the like, are integrated into a whole; one-dose effect of a pre-treatment agent is realized; inconvenient operation caused by a plurality of dosage forms and troubles, such as time consumption, labour consumption, material consumption and the like, in the production process are avoided; the use amount of auxiliary additives, such as sodium hydroxide and the like, is reduced; annealing, boiling and bleaching processes in pre-treatment are combined into the one-bath method; the process flow is simplified; simultaneously, the pre-treatment temperature is reduced; the comprehensive production cost is also reduced; and the one-dose one-bath low-temperature type pre-treatment compound preparation disclosed by the invention has good application prospect.

Description

technical field [0001] The invention belongs to the field of pretreatment compound preparations, in particular to a one-dose, one-bath low-temperature pretreatment compound preparation. Background technique [0002] The textile industry mostly adopts the traditional pre-treatment process of printing and dyeing, relying on strong acid, strong alkali and high temperature to treat cotton fabrics, which not only damages the fiber strength, but also increases the difficulty of wastewater treatment, causing serious environmental pollution. With the enhancement of people's awareness of environmental protection and the improvement of the threshold of environmental protection laws and regulations, energy-saving and environmental protection technology has become an urgent technology for printing and dyeing manufacturers. [0003] CN102587121A discloses a solid low-temperature pretreatment compound preparation. Although the enzyme preparation and oxygen bleaching activator in the abov...

AI Technical Summary

Problems solved by technology

Although the enzyme preparation and oxygen bleaching activator in the above-mentioned documents can reduce the treatment temperature, there are still the following defects: first, the composition change of the compound enzyme preparation seriously affects the effect on scouring and bleaching; Sensitivity to temperature, pH, and oxidants will affect the reproducibility of the entire process; third, the amount of bleach activator is high, and the cost of auxiliary agents is high

Although the low-temperature scouring and bleaching agent in the above-mentioned documents combines most of the auxiliary agents in the pretreatment process into one agent, it still needs hydrogen peroxide to be used for bleaching, so it cannot be called a real one-agent pretreatment agent. treatment preparation
