A kind of extraction method of plant-based batik pigment and its application method

Abstract

The invention discloses an extraction method and using method of plant wax printing pigment, and relates to the technical field of wax printing. The extraction method comprises the following steps of:commonly pulverizing indigo plants, yellow avens and calanthe discolor, and then carrying out superfine pulverization, and finally carrying out supercritical extraction on submicron powder to obtainthe plant wax printing pigment. The using method of the plant wax printing pigment comprises the following steps of: firstly putting a fabric into an alums solution, soaking the fabric, then putting the fabric into a pigment solution, boiling and airing the same. The extraction method has high extraction efficiency; the prepared pigment has good solubility, a rapid oxidation property, high dyeingefficiency and a very high economic value, is convenient to store and is simple and convenient to use.

Description

technical field [0001] The invention relates to the technical field of batik, in particular to a method for extracting plant-based batik pigments and a method for using the same. Background technique [0002] Natural plant dyes are non-toxic, ecological, soft in color, natural and distinctive, and they have good environmental compatibility and pharmaceutical health care performance, and have broad development prospects. From the current dyeing process of natural plant dyes, most of the dyes are extracted by heating with water or solvents, and the dye solution is directly used in the dyeing of textiles (Jia Na, Gong Jianpei. Pigment extraction and dyeing of yellow series of common plant dyes, dyeing Whole Technology [J], 2006, Volume 28 (3): 24-27; Chinese Invention Patent Publication No.: CN 1204667, a kind of natural plant yellow pigment for blankets and its preparation and use). This method has following shortcoming, 1. dyestuff part is thermally decomposed, and stability...

AI Technical Summary

Problems solved by technology

Furthermore, due to the instability of some pigments in natural plant dyes, obvious color differences may also appear when repeated experiments are carried out under different experimental conditions. In practical applications, it is basically necessary to re-extract and filter every time, resulting in The pigment content cannot be quantified each time, and the reproducibility is even more difficult to achieve

[0003] At present, there is a lack of mature methods for extracting natural plant dyes and natural plant dye products with stable quality and excellent performance. Especially as a handicraft batik with high dye consumption, the standardized, standardized and efficient production of conventional natural dyes is more urgent.
