Problems solved by technology

However, the current research on the dyeing performance of natural plant dyes is mainly concentrated on natural protein fibers, mainly because natural fibers are polar fibers, while natural plant dyes are non-polar, and the binding force between them is small and the affinity is poor. The fixing rate and dyeing rate of fiber fabrics are low, the color of the dyed fabrics is not bright, and the dyeing fastness is low

Abstract

The invention provides a method for dyeing a modified cellulose fiber textile by a rhubarb and turmeric dye. The method comprises the following: 1. a step of modifying a quaternary ammonium group of the cellulose fiber textile, in which a modifying agent with a concentration of 50 to 60 g / l and sodium hydrate with a concentration of 12 to 18g / l react for 40 to 60 minutes at a temperature of between 64 and 75 DEG C, the bath ratio is 1:30; in the post treatment after the modification, the fiber textile is washed by hot water at a temperature of between 40 and 50 DEG C for 10 minutes, is washed by cold water, is prickled by HAC with a concentration of 2 to 3g / l for 2 minutes, is washed by water to be neutral and is dried; 2. a step of preparing the dye solution by the sodium hydrate extracting agent with a concentration of 15 to 45g / l; and 3. a step in which the modified cellulose fiber textile is dyed, washed by water and dried directly by the dyeing technique and is washed by soap, washed by water and dried. The technique is simple and easy to implement, does not need the mordanting and the fixation processes and the like, has high rate of dye-uptake, good dye quality and the friction resisting color fastness and the colorfastness to washing up to more than three grades, is nontoxic, does not pollute the environment, and has low cost, and remarkable economic benefits and environmental benefits.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, in particular to the technical field of dyeing natural plant dyes for cellulose fiber fabrics. Background technique [0002] Today, when the trend of green environmental protection is rising all over the world, textiles and clothing tend to be natural, and people yearn to return to nature. Affected by the clothing trend of "returning to basics" and "returning to nature", the utilization and industrialized production of natural dyes have become hot spots again. Natural dyes come from nature, are harmless to human health, have good compatibility with the environment, do not pollute the environment, and the dye solution is biodegradable. Dyeing with natural dyes: cellulose fiber fabrics have natural, elegant, unique and unique colors, which are not easy to reproduce, and meet people's pursuit of individuality and diversification. At the same time, they can also endow the fabric...
