Technology using vaccinium bracteatum plant dye for dyeing of black blue real silk

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. Background technique

[0002] Silk is known as the "fiber queen" and has been favored by people throughout the ages for its unique charm. Silk fabric is a kind of high-grade clothing fabric, which has pearl-like luster, smooth and elegant texture, excellent moisture absorption, breathability, skin-friendly and cosmetic properties; vegetable dyes have good biodegradability and environmental friendliness. Its dyed textiles can not only obtain the unique colors and special aromas of nature, but also have certain drug treatment or health care effects, which conform to the requirements of the development of national ecological textiles and functional textiles. Black rice plant dye is a natural dye extracted from the leaves of black rice tree. The leaves of black rice tree contain a variety ...
