Problems solved by technology

Because the dyeing temperature of 60-80°C is unstable, the color stability is also poor.
Moreover, the process of heating and cooling increases the dyeing time and consumes a lot of energy.

Abstract

The invention discloses an active dye constant-temperature dip-dying method. The method comprises the following steps: first, calico cloth is subjected to pretreatment; second, the calico cloth is dipped in a dye vat with a constant temperature of 55 DEG C; third, active dyes with a concentration of 25g / L, sodium hexametaphosphate with a concentration of 1-2 g / L, anhydrous sodium sulfate with a concentration of 4-9 g / L and soda with a concentration of 10 g / L are added in the dye vat in order; fourth, the temperature is risen to 60 DEG C, and dip-dying is carried out for 35min; fifth, the cloth is taken out and dried. The method can raise the color stability, achieve energy saving and emission reduction and lower cost under conditions that color fastness meeting requirements for quality is achieved.

Description

technical field [0001] The invention relates to a constant temperature exhaust dyeing method of reactive dyes. Background technique [0002] Reactive dyes are colored organic compounds that dye cotton fibers. The conventional reactive dyes used in the traditional process must be dyed at a high temperature of 60-80°C to meet the requirements of affinity, dyeing fastness, water solubility and level dyeing of fibers without forming lakes. Because the dyeing temperature of 60-80°C has a large range of instability, the color stability is also poor. Moreover, the operation of heating and cooling increases the dyeing time and consumes a lot of energy. Contents of the invention [0003] The purpose of the present invention is to provide a constant temperature exhaust dyeing method of reactive dyes, which can improve the color stability and realize energy saving, emission reduction and cost reduction under the condition of achieving the color fastness required by the quality. ...
