Abstract

The invention provides a Dioscorea cirrhosa natural dye and an application thereof. A method for preparing the natural dye comprises the following steps: weighing 10 to 30 parts of a dioscorea cirrhosa extract and 0.5 to 5 parts of an acidic solution, uniformly mixing the materials and performing standing for 3-6 h to obtain a red mud-like object, drying and solidifying the red mud-like object, and pulverizing the red mud-like object to obtain the dioscorea cirrhosa natural dye. The natural dye has the advantages of high pigment adsorption power, strong color fastness, uniform dyeing, simple extraction process, high extraction efficiency, low cost, wide market prospect, sterilization effect, and good compatibility with the ecological environment, and is biodegradable, and can be applied tothe prevention and control of pests and diseases.

Description

technical field [0001] The invention belongs to the technical field of dye production, and in particular relates to a natural dye of yam yam and its application. Background technique [0002] The use of natural dyes for dyeing can be traced back to the Neolithic Age, and in China, the pigments extracted from the roots, stems, bark, leaves and flowers of natural plants can be used for dyeing yarns and textiles. The history can be traced back to more than 5,000 years ago and has continued to the middle of the 19th century. The invention of synthetic dyes triggered a precipitous decline in natural dyes. However, the use of chemical dyes has had a profound negative impact on human health and the ecological environment. Plant dyes have been favored by people for their non-toxic, harmful, non-polluting, elegant and beautiful colors, especially their pharmacological health care functions. As a result, in the early 2000s, the fashion industry saw a growing demand for products usin...
