Abstract

The invention provides a silk fabric staining method by using gardenin, the silk fabric staining method comprises the following steps: dissolving the gardenin into a carbon tetrachloride/phenol mixed solution, then adding a surfactant sodium dodecyl benzene sulfonate, obtaining a transparent solution under ultrasonic; putting a silk fabric into the transparent solution, oscillating and heating up to 30 to 60 DEG C to be stained. The staining technique provided by the invention has the advantages that modification on the gardenin is not needed, high temperature staining is not adopted, and the stained 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 gardenia. Background technique [0002] Gardenia is a natural pigment extracted from Rubiaceae gardenia, which is a flavonoid compound. Gardenia can be dyed with different mordants to obtain different shades of deep and light yellow. Gardenia pigment is the most widely used yellow vegetable dye since the Qin and Han Dynasties. However, gardenia 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 gardenoin effectively dye silk fabrics, the present invention takes the following technical solutions. [0004] A method for dyeing silk fabrics with gardenia, comprising the following steps: (1) dissolving phenol in carbon tetrachloride; (2) dissolving gardenia in a carbon tetrachloride / phenol mixed solution, and then adding Surfactant sodium dodecyl...
