Abstract

The invention discloses a printing and dyeing process of a knitted fabric. The printing and dyeing process comprises the following steps: 1) taking 6-7 parts by mass of a refining agent, 3-5 parts by mass of hydrogen peroxide, 8-9 parts by mass of an alkali, 4-7 parts by mass of a brightening agent for treating a grey fabric, dewatering and shaping; 2) preparing stencil printing paste, using a rotary screen printing machine for printing and completing burnout printing; 4) well preparing pattern forming paste; and using the rotary screen printing machine for printing with the temperature of a drying room of 125 DEG C to complete the dispersion activity same-paste printing; 5) baking at 165-170 DEG C for 4 to 6 minutes; 6) adopting a wet shortened steaming device for surface rolling of a color fixing solution containing 7g / L of borax, 17g / L of caustic soda and 35g / L of sodium silicate, with the mangle expression being 75%, the steaming temperature being 135 DEG C and the ageing time being 4 to 5 minutes; 7) performing water washing by selecting of a continuous rope-like water washing machine, and using a centrifuge for dehydrating; and 8) softening and shaping. The printing and dyeing process disclosed by the invention has the characteristics of high fixation rate of dyes, simplicity in operation and small environmental pollution.

Description

technical field [0001] The invention relates to a printing and dyeing process for knitted fabrics. Background technique [0002] In addition to the long process route, high cost and difficult quality control, the existing conventional reactive dye printing and dyeing process also has the problem of serious environmental pollution caused by sewage discharge. Contents of the invention [0003] The object of the present invention is to provide a printing and dyeing process for knitted fabrics, which has high dye fixation rate, simple operation and little environmental pollution. [0004] In order to achieve the above object, the technical solution of the present invention is to design a kind of printing and dyeing process of knitted fabric, comprising the steps: [0005] 1) Treat gray cloth with 6-7 parts by mass of refining agent, 3-5 parts by mass of hydrogen peroxide, 8-9 parts by mass of alkali, and 4-7 parts by mass of whitening agent, and dehydrate and shape it; [00...
