Abstract

The invention discloses a double-color type dye-pasting method for plant dye teaching, which belongs to the technical field of dyeing, and takes dye-proofing paste, plant dye liquor, mordant and the like as materials, and is prepared into a fabric with double-color patterns after the operations of scraping the dye-proofing paste, plant dye and mordant, in particular to a fabric which forms a color pattern darker than the color of surrounding areas in the area of the dye-proofing paste. The double-color type paste dyeing method for plant dyeing teaching fills the blank of single color layer of traditional paste dyeing, and provides a course development mode combining traditional process, scientific research and artistic practice.

Description

Double-color type dye pasting method for plant dye teaching Technical Field The invention relates to a double-color type paste dyeing method for plant dyeing teaching, and belongs to the technical field of dyeing. Background The plant dyeing belongs to the traditional dyeing method in China, and is a dyeing process using natural raw materials such as roots, stems, leaves, flowers, fruits and the like of plants as dyes, and has the characteristics of natural environment protection and mild color. In order to better spread the non-genetic culture of plant dyeing, a plurality of campuses develop plant dyeing courses, so that students can feel the charm of the traditional process in the courses, and the practical ability and aesthetic ability of children are cultivated. Plant dyeing includes various traditional techniques, wherein direct dip dyeing can only achieve a single-color effect, and tie dyeing relies on random textures, so that accurate pattern control is difficult. The traditional paste dyeing can be used for preparing blue-white printed cloth, the material is a hollowed-out template and anti-dyeing paste, and the anti-dyeing paste is usually prepared by mixing soybean powder and lime. During operation, under the assistance of the hollowed-out template, the anti-dyeing paste is leaked and printed on the surface of the fabric, the fabric is immersed in the plant dye liquor after the anti-dyeing paste is semi-dried or completely dried, and finally the anti-dyeing paste is washed off to show patterns. Although the traditional dye paste can shape patterns, the traditional dye paste presents single contrast color by 'anti-dye white-keeping', and cannot form fine and smooth color depth layers on the same piece of fabric, so that artistic creation dimension and technological exploration space are limited. Disclosure of Invention The invention aims to solve the problems in the prior art, provides a double-color type paste dyeing method for plant dyeing teaching, increases the fixation amount of a pattern area through the synergistic effect of paste dyeing prevention components, paste removing operation, plant dyeing and mordant dyeing, fills up the blank of single color layer of the traditional paste dyeing, and provides a course development mode integrating the traditional process, scientific research and artistic practice.
