Abstract

The invention discloses a stepped coloring process of a reactive dye. The process comprises the following steps of: (1) firstly, preparing the pre-processed all-cotton knitted fabric, and marking; (2) dripping the dye prepared according to a formula and a bath ratio into a dyeing cup; (3) putting the dyeing cup with the dye and the dyeing liquid in the all-cotton knitted fabric marked in turn, and putting the dyeing cup in a proofing jar; (4) taking the all-cotton knitted fabric out of the proofing jar in turn, and maintaining the dyeing liquid; and (5) washing the all-cotton knitted fabric with water, neutralizing with acetic acid, and then soaping and drying. Through the stepped coloring process of the reactive dye disclosed by the invention, abnormal situations such as dyeing defect, edge-middle color difference and the like can be prevented in advance, the product quality can be effectively ensured and improved, and the cost of maintaining due to the abnormal situations is lowered.

Description

technical field [0001] The invention relates to a reactive dye step-by-step coloring process. Background technique [0002] Cotton fiber is a hydrophilic fiber. Because of its advantages such as air permeability and moisture permeability, the cotton fabric series products woven into it have always been loved by people because of their comfort. However, with the improvement of people's living standards, people have higher and higher requirements for fabrics. In addition to requiring comfort and functional requirements, fabrics are also required to have diversity and aesthetics. The perfect combination of functionality and aesthetics is the ultimate pursuit of the textile fabric industry. [0003] At present, domestic manufacturers use sulfur dyes to dye cotton fabrics. The dyeing process is: dyeing cotton fibers with sulfur dyes, steaming (fixing), washing, oxidation, soaping, washing, and drying (dyed fabrics); For cotton fabric dyeing technology, there are problems such a...
