Abstract

The invention provides a preparation method and application of a natural plant dye solution of Phytolacca acinosa berries. The preparation method comprises the following steps: cleaning Phytolacca acinosa berries, draining, and grinding to obtain Phytolacca acinosa berry pulp; adding water to the Phytolacca acinosa berry pulp (the weight ratio of the Phytolacca acinosa berry pulp to the water is 1:(3-6), immersing at normal temperature under sealed conditions for 1-2 hours, and leaching once or twice; and merging the leaching solutions, and filtering to obtain the natural plant dye solution of Phytolacca acinosa berries. The application method comprises the following steps: dyeing fabric by a chrome-free dyeing, pre-chrome dyeing, metachrome dyeing or after-chrome dyeing process, taking out the fabric, flushing with water and drying in the shade. The natural dye is extracted from the waste Phytolacca acinosa berries and used for dyeing the fabric, thereby recycling the waste Phytolacca acinosa berries, increasing the dyeing types of textiles and enhancing the grade of the textiles, and is especially suitable for dyeing silk fabric and wool fabric. The preparation method and dyeing technique of the natural plant dye solution are simple, and have very broad market prospects.

Description

technical field [0001] The invention relates to a preparation method and application of natural dye, in particular to a preparation method and application of pokeweed berry natural plant dye solution. Background technique [0002] At present, most of the dyes used in textile dyeing are synthetic dyes, and their raw materials and intermediates are derived from petroleum, a large part of which is toxic substances, and the production process of dyes not only seriously pollutes the environment, but also causes serious harm to the wearer or production. cause direct and indirect harm. With the continuous enhancement of people's environmental protection and health awareness, traditional natural plant dyes have aroused people's attention again in order to pursue a higher quality of life. Natural dyes have good compatibility with the environment, are biodegradable, non-toxic and even have certain health care functions. In addition, natural dyes are rich in natural resources, and the...
