Abstract

The invention relates to a caustic alkali for printing and dyeing, characterized in that it comprises 10%-20% by wt of disodium hydrogen phosphate, 15%-30% by wt of sodium hydroxide, 5%-18% by wt of sodium carbonate, 1%-10% by wt of potassium carbonate, 0.1%-2% by wt of organic ene acid, 1.6%-16% by wt of organic phosphonic acid, 0.01%-5% by wt of organic carboxylic acid, 0.01%-2% by wt of crown ether and water. The manufacturing method for said caustic alkali for printing and dyeing contains that organic phosphonic acid, organic carboxylic acid, organic ene acid and water are poured into the reaction vessel and mixed evenly; the temperature is increased to 120-140DEG C gradually; K+18-crown-6 crown ether is dropped into it, the mixture is mixed round and the temperature is decreased to normal temperature; then sodium hydroxide is added into it and the temperature is increased to 120-140DEG C; after that sodium carbonate is added into it and the temperature is maintained to air discharging; finally disodium hydrogen phosphate is added into and the temperature is maintained for 6-8 hours.

Description

technical field [0001] The invention relates to an auxiliary agent for textile printing and dyeing, in particular to a novel alkali agent used as a scouring agent and a color-fixing agent and a preparation method thereof. Background technique [0002] Soda ash or trisodium phosphate or caustic soda is commonly used as scouring agent and color fixing agent in the traditional textile printing and dyeing process, but in actual production, due to the many shortcomings of pure soda ash and caustic soda in the printing and dyeing process, there have been substitutes, such as The prior invention patent application "a liquid color-fixing alkali agent for reactive dye dyeing", patent application number 200510050261.5, discloses a technical solution in this patent application, providing a liquid that replaces solid soda ash in the color-fixing process of reactive dyes Fixing dye, but this kind of dye still has some shortcomings, for example: the scope of application is not wide enough...
