Abstract

The invention discloses a functional compound dyeing acid, which comprises the following components: glacial acetic acid, formic acid, EDTA, penetrant, modified graphene oxide, dispersant and deionized water. The acid component of the compound dyeing acid is mainly provided by glacial acetic acid and formic acid. In order to reduce the influence of the dye on the dyeing acid, a complexing agent EDTA is added, and the addition of a penetrating agent can improve the penetration effect of the dyeing acid and shorten the dyeing time; and this The silicon-containing modified graphene oxide and silicon-containing hyperdispersant used in the invention can not only significantly improve the dispersion effect of dyeing acid, shorten the dyeing time, reduce the amount of dyeing auxiliaries, but also reduce the yellowing of fabrics caused by formic acid Effect, thereby enhancing the vividness of fabric dyeing.

Description

technical field [0001] The invention relates to the technical field of textile auxiliaries, in particular to a functional compound dyeing acid. Background technique [0002] Dyeing acid is also known as substitute acid, penetrating acid, and buffer acid. Dyeing acid has two functions in dyeing: one is to adjust the pH value to meet the pH value required for dyeing; the other is to pickle and neutralize the alkali agent added in the dyeing process. Therefore, the dyeing acid must first test the adjustment ability of the pH value. Usually, the acidity meter is used to test the pH value at 0.5g / L and 1.0g / L to evaluate its pH adjustment ability; the simplest test method for neutralization ability: prepare 1.0g / L soda ash solution, neutralized with dyed acid to pH = 7, see the amount of dyed acid consumed. Many dyeing acids on the market have poor neutralization ability and can only be used for pH adjustment. The organic acid with the strongest neutralization ability is form...
