Abstract

The invention provides a tobacco natural plant dye, a preparation method, and an application thereof. The tobacco natural plant dye is prepared from fresh tobacco as a raw material, which is washed with a surfactant and is subjected to bio-pretreatment impurity removal to obtain tobacco powder. The tobacco powder is extracted by a water solution or an ethanol water solution, wherein the pH value of the solution is controlled by NaHCO3 or ethylenediamine; the solution is subjected to heating extraction and is filtered to produce a natural dye stock liquid, which is concentrated, solidified and crushed to obtain the tobacco natural plant dye. In the method, tobacco pigments are used as natural dyes in the dyeing and finishing industry. The preparation method is simple and is high-effective. The tobacco natural plant dye can dye cotton, wool, cashmere and the like. Through regulation on a direct dyeing process, a pre-mordant dyeing process or a same-mordant dyeing process and types of mordants, fabrics in brown color, yellow-brown color, light-brown color, yellow color or green color can be produced. The dyed fabric has high color fastness to rubbing, has natural and gentle gloss and significantly improves usage value of tobacco and application value of the fabrics.

Description

technical field [0001] The invention belongs to the technical field of textile materials, in particular relates to natural dyes and their production and application, in particular to a tobacco natural plant dye and its preparation method and application. Background technique [0002] With the irreversible consumption of earth's oil resources and serious environmental pollution, under the influence of the global green wave, people are paying more and more attention to environmental and health issues, and some synthetic dyes have more and more negative effects on human health and the ecological environment. More attention has been paid to it. There are more than 20 kinds of carcinogenic aromatic amines, more than 100 synthetic dyes that may produce carcinogens, and dozens of dyes that are allergic to the skin. Therefore, it is imperative to develop natural and environmentally friendly dyes and environmentally friendly and clean dyeing processes. Natural environmental protectio...
