Abstract
The invention provides a method for dyeing a silk fabric with sophora flower yellow. The method comprises the following steps: dissolving sophora flower yellow into a carbon tetrachloride / phenolmixed solution, further adding a surfactant sodium dodecyl benzenesulfonate, and performing ultrasonic treatment so as to obtain a transparent solution; putting the silk fabric into the solution, oscillating and heating to 30-60 DEG C, and dyeing the silk fabric. By adopting the dyeing technique, the sophora flower yellow does not need to be modified, high-temperature dyeing is avoided, and a dyed fabric is high in color fastness.
Description
technical field [0001] The invention relates to the technical field of textile dyeing, in particular to a method for dyeing silk fabrics with sophoraxanthin. Background technique [0002] The pigment component in Sophorajaponica is pilocarpine, also known as sophoraxanthin. Sophoraxanthin is a flavonoid derivative. Sophoraxanthin is hardly insoluble in water. It is a yellow dye with bright color and excellent fastness. It has good compatibility with the environment and is harmless to human health. However, sophoraxanthin is poor in direct dyeing of protein fibers such as silk, and its color fastness is poor. Contents of the invention [0003] In order to make sophoraxanthin effectively dye silk fabrics, the present invention takes the following technical solutions. [0004] A method for dyeing silk fabrics with sophoraxanthin, comprising the following steps: (1) dissolving phenol in carbon tetrachloride; (2) dissolving sophoraxanthin in a carbon tetrachloride / phenol mi...
