Technical Field
The invention relates to the technical field of wax printing, in particular to an extraction method and a use method of a vegetable wax printing pigment.
Background
The natural plant dye is nontoxic, ecological, soft in color, natural and distinctive, and has good environmental compatibility and medicinal health care performance, and has a wide development prospect, from the current dyeing process of the natural plant dye, most of the dye is extracted by heating through water or a solvent, and the dye liquor is directly used for dyeing textiles (jiana, goer culture, pigment extraction and dyeing of common plant dye yellow system, dyeing and finishing technology [ J ], 2006, volume 28 (3): 24-27; Chinese patent publication No. CN 1204667, a blanket natural plant positive yellow pigment and a preparation and use method thereof), the method has the defects that ① dye is partially decomposed by heat, the sublimation characteristic of the natural plant dye with poor stability ② is damaged ③ and easy to rot, the storage and dyeing reproducibility of ④ are not easy to master (stillness, Jiaxia. the current situation and development of the application of the natural dye, new textile [ J ], 2005-28 (4), (26-28) is taken, the natural plant dye is influenced by geographical environment, the climate condition of phellodendron, the phellodendron bark is different from the natural plant dye, even if the natural plant dye is extracted, the natural plant pigment content is different from the natural plant pigment, the natural plant pigment is not easily found, the natural plant pigment is different from the natural plant pigment, the natural plant pigment is not easy to be extracted, the repeated, the yellow pigment extraction condition is not easily found, the yellow pigment is different from the natural pigment extraction condition, the natural pigment extraction condition of the yellow pigment extraction condition is not obviously, the yellow pigment extraction condition of the yellow pigment is different from the yellow pigment.
At present, a mature method for extracting natural plant dyes and a natural plant dye product with stable quality and excellent performance are lacked, and particularly, the natural plant dye product is used as a craft wax printing product with high dye consumption, and the standardized, standardized and efficient production of the conventional natural dyes is more urgent.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides an extraction method of a vegetable wax printing pigment and a using method thereof, so as to promote the high-efficiency production of the wax printing pigment and improve the dyeing effect of the pigment.
The method is realized by the following technical scheme:
a method for extracting vegetable wax printing pigment comprises the following steps:
(1) preparing raw materials: mixing Polygonum tinctorium, Ardisia japonica and calanthe, drying at normal temperature and low pressure until the water content is lower than 8%, and pulverizing Polygonum tinctorium, Ardisia japonica and calanthe in a conventional electric pulverizer to obtain common powder;
(2) extracting, namely adding common powder into a vibrating type ultrafine pulverizer, pulverizing for 30min at 25-35 ℃ to obtain ultrafine powder, putting the ultrafine powder into a supercritical extraction tank, taking CO2 as an extraction fluid and ethanol as an entrainer, wherein the dosage of the ethanol is 0.5-0.7m L/g, the extraction pressure is 50-80Mpa, the extraction temperature is 45-50 ℃, and the extraction time is 2-2.5h, and performing supercritical extraction to obtain the vegetable batik pigment;
further, in the step (1), the mass ratio of the polygonum tinctorium to the roadside green to the calanthe is 10:8: 1.
Further, in the step (1), the normal temperature and the low pressure are 25-30 ℃ and 0.1-0.3 standard atmospheric pressure.
The use method of the vegetable wax printing pigment comprises the following steps:
(1) preparing a solution with the mass concentration of 3-5% by using vegetable wax printing pigment and distilled water to obtain a dye solution;
(2) adding the fabric into an alum solution, soaking for 40-60min, directly taking out the fabric, putting the fabric into a dye solution, boiling for 2-3h, taking out the fabric, and spreading and airing the fabric for 2-3 weeks in a ventilated environment.
Further, the mass ratio of the fabric to the alum solution is 1: 40; the concentration of the alum solution is 5%, and the temperature is 85 ℃.
Further, the mass ratio of the fabric to the dye is 1: 35.
The invention has the beneficial effects that:
(1) the invention reasonably configures color series through scientific proportioning among raw materials, so that the color of the fabric dyed by the pigment wax is soft and permanent, and the invention firstly dries and crushes the raw materials, then carries out superfine crushing, and then carries out supercritical extraction, the extraction condition is mild, the supercritical extraction efficiency is high, the pigment loss is small in the manufacturing process, the components such as sugar, plant protein and the like in plants are also kept, the adhesion and solidification of the pigment on the fabric are promoted, in use, the invention fully combines the complexation between natural pigment and inorganic ions, and the pigment effect is furthest shown through coordinating the dyeing condition, and the pattern color forming effect is improved.
(2) The pigment prepared by the method has good solubility, rapid oxidation and high dyeing efficiency, and the pigment is convenient to store, simple and convenient to use and has excellent economic value.
