Abstract

The invention belongs to the technical field of printing and dyeing and specifically discloses a method for dyeing with a bletilla striata dye. The method comprises A, pre-treatment, B, dyeing: based on a dyeing device, a, dissolving a bletilla striata dye in 100 ml of water, adding 1 L of clear water into the dye solution, carrying out full stirring and keeping a dye liquid temperature at 100 DEG C to obtain a bletilla striata dye liquid, b, pouring 1 / 2 of the bletilla striata dye liquid into a dye liquid cylinder, pouring the rest of the bletilla striata dye liquid into a dyeing vessel and paving 1-5 layers of cloths on a stainless steel plate, c, starting a driving mechanism to drive the stainless steel plate to move up and down and stopping the driving mechanism after 15-20min, and d, turning the cloth over and repeating the step c, C, color fixation and D, rinsing. Compared with the traditional dyeing method, the method can improve dyed cloth color fastness.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a method for dyeing bletilla striata dye. Background technique [0002] Vegetable dyes are dyes extracted from plants for fabric dyeing. At the beginning of the 20th century, since the advent of chemically synthesized dyes, vegetable dyes gradually withdrew from the dye market due to the excellent dyeing performance, numerous varieties and low cost of synthetic dyes. In recent years, with the enhancement of people's awareness of environmental protection, they have gradually realized that chemically synthesized dyes will cause serious damage and damage to human health and the environment, so people have re-upgraded vegetable dyes. [0003] Plant dyes use the stems, leaves, fruits, seeds, skins and roots of natural flowers and trees to extract pigments as dyes, which are non-toxic and harmless, and will not cause any harm to human health. The dyed fabric has natural c...
