Embodiment 1

[0016] A fabric printing and dyeing process, the steps of which include greige inspection, cylinder matching, stitching, boiling and bleaching, and dyeing, wherein the specific process of the step of boiling and bleaching is as follows:

[0017] 1) Add 1.5% owf refining agent, 0.8% owf stabilizer, and 6.0% owf caustic soda to the overflow dyeing machine, control the temperature in the overflow dyeing machine at 60°C, and boil and wash for 30 minutes;

[0018] 2) Heat at a heating rate of 1.5°C per minute, keep warm when the temperature reaches 80°C, add 8.0% owf hydrogen peroxide, and keep warm for 30 minutes;

[0019] 3) Heat at a heating rate of 1.5°C per minute, heat to 98°C, and keep warm for 30 minutes;

[0020] 4) Wash the gray cloth in the overflow dyeing machine with clean water at normal temperature to complete the boiling and bleaching step.

[0021] Wherein, before the boiling and bleaching starts, the liquor ratio is 1:15.

[0022] The scouring agent is composed ...

Abstract

The invention discloses a fabric printing and dyeing process. The fabric printing and dyeing process comprises the steps of gray fabric inspection, cylinder matching, sewing, scouring and bleaching, and dyeing. The step of scouring and bleaching comprises the following sub-steps: (1) adding 1.2-1.8 percent owf (On Weight of Fabric) of refining agent, 0.8-1.0 percent owf of a stabilizing agent and 5.0-6.0 percent owf of caustic soda into an overflow dyeing machine, controlling the temperature in the overflow dyeing machine to be 60 DEG C, and scouring for 30 min; (2) heating at the heating speed of 1.5 DEG C per minute, maintaining the temperature when the temperature reaches 80 DEG C, adding 7.0-9.0 percent owf of hydrogen peroxide, and maintaining the temperature for 30 min; (3) heating at the heating speed of 1.5 DEG C per minute until the temperature reaches 95-98 DEG C, and maintaining the temperature for 30 min; (4) cleaning a gray fabric in the overflow dyeing machine by using normal-temperature clean water, so that the step of scouring and bleaching is completed. According to the fabric printing and dyeing process, the gray fabric can be more easily dyed, the dyeing uniformity is higher, the printing and dyeing time is shortened, and the environmental friendliness of the process is good.

Description

technical field [0001] The invention relates to the field of printing and dyeing technology. Background technique [0002] Fabrics that have not been dyed and finished are collectively referred to as raw fabrics or gray fabrics. The purpose of the pre-printing and dyeing treatment is to remove all kinds of impurities on the fabric with little damage to the gray fabric, so that the gray fabric becomes a white, soft and printing and dyeing semi-finished product with good wetting properties. Pretreatment of printing and dyeing is the preparatory process of printing and dyeing processing, also known as scouring and bleaching. For the pretreatment of cotton and cotton-type fabrics, there are processes such as preparation, singeing, desizing, scouring, bleaching, and mercerizing. Some existing pretreatment liquids of printing and dyeing processes, due to the low coupling rate of dye groups and fibers, low adsorption rate of dye molecules on fibers, and poor stability, resulting i...
