Embodiment 1

[0020] In the present embodiment, the black rice leaf vegetable dyestuff is used for the technique of real silk dyeing, mainly comprises the following steps:

[0021] (1) Extraction of plant dyes from black rice leaves

[0022] Take fresh black rice leaves and wash them at room temperature, then wash them again with deionized water, dry the water on the surface of the leaves naturally, weigh them, cut the leaves of black rice leaves into small pieces of 5 mm × 10 mm with clean scissors, and divide them according to the size of the leaves and 60 ℃ mixed with deionized water at a mass ratio of 1:10 to 1:15 to make a slurry, leached in a shaking water bath at 50 to 60 ℃ for 2 to 3 hours, vacuum filtered, and took the filtrate for later use;

[0023] (2) Dyeing of blue-black silk

[0024] Wet the silk to be dyed which is half the mass of the leaves of black rice leaves in normal temperature water for 15 minutes, squeeze it dry, put it into the above standby filtrate with a bath r...

Abstract

The present invention relates to a technology using a vaccinium bracteatum plant dye for dyeing of real silk, the technology includes 60 DEG C water bath extraction of the vaccinium bracteatum plant dye and low temperature environmental-friendly dyeing, the dyeing is as follows: wetting real silk, squeezing to dry, putting the real silk into the plant dye with the bath ratio of 1:20 to 1: 30, adding a mordant or not, heating the water bath to 50-75 DEG C at a heating rate of 1.5 DEG C / min for thermal insulation dyeing for 1-2h; taking a dyeing cup out, standing at room temperature for 7-8h; after the dyeing, steaming the real silk at the temperature of 100-103 DEG C for 10-15min, after washing with water, boiling with soap at 90-100 DEG C for 5-10min, and finally drying at 50-60 DEG C. The obtained real silk has a rare black blue color and special natural flower and plant fresh scent.

Description

technical field [0001] The invention belongs to the dyeing process of real silk, and in particular relates to a dyeing process of blue-black real silk with the plant dye of black rice leaves.
