Abstract

The invention discloses a method for printing and dyeing cotton fabrics with a natural plant as a dye. According to the invention, through reasonable selection of a mordant and reasonable design of a printing and dyeing process, color fastness of a printed and dyed cotton fabric is improved, and in particular, color fastness to rubbing under wet conditions is substantial improved on the premise that weathering color fastness and color fastness to rubbing under dry conditions are enhanced; therefore, user demands are met, and wash durability of the cotton fabric is enhanced.

Description

technical field [0001] The invention relates to a printing and dyeing method, in particular to a method for printing and dyeing cotton fabrics using natural plants as dyes, and belongs to the field of printing and dyeing. Background technique [0002] In recent years, the world has been very concerned about the deterioration of environmental quality and the imbalance of ecological balance. Human beings are facing the most serious environmental crisis in history. Most of the environmental pollution is directly related to the pollution of industries and industrial products. Aromatic amines, as dye intermediates, have been listed as suspected carcinogens by government agencies in some countries, and benzylamine in benzidine has been identified as the most potent carcinogen to humans. According to the requirements of ecological textiles and since 118 dyes were banned, environmentally friendly dyes have become the focus of the development of the dye industry and the printing and ...
