Mild safe high color light stable ph buffer system, method of making and use thereof

Abstract

The present application belongs to the field of textile printing and dyeing, and relates to a mild, safe, high-color and light-stable pH buffer system, a preparation method and application thereof. The pH buffer system comprises: regulator A, regulator B, complexing agent, penetrating agent, silicon-modified graphene oxide and silicon-containing dispersant. The regulator A is at least one of malic acid, citric acid, acetic acid and ammonium sulfate, and the regulator B is composed of organic acid, which is carboxylic acid or sulfonic acid. By limiting the specific weight ratio of the regulator A and the regulator B, the regulator A, the regulator B, the silicon-modified graphene oxide and the silicon-containing dispersant play a synergistic effect, and the pH buffer system is obtained. The pH buffer system is applied to dyeing, has excellent pH value buffering performance, and the pH value of the working solution is stable before and after dyeing. The dyeing color light is bright, the reproducibility is excellent, and has no obvious influence on the dyeing color light and depth. The strength of cotton and viscose components in polyester-cotton and polyester-viscose blended or interwoven fabrics is not affected.
