Abstract

The invention relates to a process for dyeing cotton cheese by using natural dye, belonging to the technical field of textile printing and dyeing. A two-step method is adopted to complete dyeing on the cotton cheese by using the natural dye, namely firstly modifying the cotton cheese by virtue of high pressure spray and then dyeing, thus the natural dye can have good dyeing depth and leveling property on one hand, on the other hand, the leveling property problem in dyeing by using the natural dye can be effectively solved.

Description

technical field [0001] The invention relates to a process for dyeing cotton cheese with natural dyes, which belongs to the technical field of textile printing and dyeing. technical background [0002] With the continuous enhancement of people's awareness of environmental protection and the continuous reduction of petroleum resources, seeking a natural dye that is environmentally friendly, healthy, non-toxic, harmless, non-polluting, elegant and beautiful in color, and has pharmacological health care functions has been favored by people. Especially in recent years, with the diversification of market consumption and the need to return to nature, natural dyes have made great progress in the textile printing and dyeing industry. [0003] In my country, many experts including Heilan Group and Donghua University have carried out research on the extraction method and dyeing of natural dyes with the support of the national 863 high-tech project. A number of experts from Shanghai Ji...
