soda ash, also known as alkali washing, light and heavy, according to the purpose, and the consumption level and the industrial division, today we will learn about the application of soda ash on printing and dyeing industry. A water softener
printing and dyeing process, in order not to make a deposit, need to remove the calcium and magnesium ions in the water, adding soda ash in the water can make the calcium and magnesium ions in the water carbonate precipitation, thereby achieve the role of softening. two colored yarn fabric yarn fabric with scouring agent in the article, most of colored yarn dye with sulfide, VAT dyes, if under high temperature and high pressure with alkali soluble fall easily, cause serious color, so it with soda instead. three practice MAO agent combined with soap as a much dust amount of impurity is contained in raw wool fibre, is not suitable for textile, so will the wool washing. It is commonly use soap and soda ash, remove impurities on the wool. Four silk silk practice with agent is mainly silk sericin paper, fiber and other impurities are very few, only a trace of wax fat. Silk gum can be softened in soap and soda ash of hot water dissolving, silk fiber will not dissolve, using it can be separated. five additives used for dyeing cotton soda ash can be directly used for dyeing cotton additives, can have the effect of break through and softening hard water. In the process of sulfide, if alcali sulphide efficacy is not enough, you can join soda ash for auxiliary dye. six dyeing fixing agent for printing and dyeing process, the reactive dyes by alkaline content of solid color, with a mild alkaline substances better effect is good, so the soda ash becomes the best fixing agent. soda ash also many, for more soda ash industry USES, the appropriate consulting Shanghai xin chemical industry co. , LTD. !
