Abstract

The invention discloses a method for dyeing cotton fabric with gardenia blue pigment. The dyeing method comprises the following steps of pre-mordant treatment-dyeing-post-mordant treatment-treated cotton fabric dyeing. In pre-mordant treatment liquid, the dosage of mordant is 1%-6% (owf); in dyeing liquid, the dosage of the gardenia blue pigment is 2%-5% (owf), the dosage of anhydrous sodium sulfate is 20-40 g / L; in post-mordant treatment liquid, the dosage of the mordant is 1%-6% (owf). According to the method for dyeing the cotton fabric with the gardenia blue pigment, the environment-friendly type mordant is used to meet the people's requirements of environmental protection and physical health; the pre-mordant treatment can reduce the repulsion effect between the gardenia blue pigment and cotton fiber, and improve the dyeing percentage; the post-mordant treatment can improve the color fastness of dyeing fabric; zinc sulfate, lanthanum chloride, cerium chloride and aluminum sulfate are used as the mordant, bright blue cotton fabric can be obtained, wherein the brightness of the dyeing fabric is the highest by using the zinc sulfate as the mordant.

Description

technical field [0001] The invention belongs to the technical field of dyeing and finishing of fabrics, and in particular relates to a method for plain dyeing cotton fabrics with gardenia blue. Background technique [0002] With the gradual improvement of people's life modernization, protecting the common living environment of mankind and realizing sustainable development has gradually become the main direction of economic development in all countries in the world. People pay more and more attention to the safety and health of textiles and textile chemicals. Natural Pigment has once again attracted the attention of relevant researchers with its unique characteristics. [0003] In recent years, many researchers at home and abroad have carried out a lot of development and research on the application of natural pigments in textile dyeing. Among them, the research on warm colors such as red, yellow, and brown is the main research, while there is little research on cool blue colo...
