Abstract

The invention relates to the technical field of natural dyes, in particular to a natural dye dyeing method (watermelon red), and aims to solve the problems of non-uniform dyeing and difficult coloringformation in the prior art. The natural dye dyeing method is technically characterized by comprising the following steps that: S1, dyeing: putting a dye, a mordant and yarns into clear water, continuously heating them to a certain temperature for dyeing, and washing with water at room temperature after dyeing is finished; S2, soft water washing: adding the yarns processed in the step S1 into softwater, and continuously heating the soft water; and S3, soaping: adding a soaping agent and the yarns processed in the step S2 into clear water, continuously heating them to a certain stable temperature, performing processing for a certain time, and washing with water after the processing is finished. The watermelon natural dye is used as the dye to dye the yarns, and the initial PH value of dyeing is controlled, so that the dye can uniformly dye the yarns, and the situation that the surface color of the yarns is not uniform is avoided.

Description

technical field [0001] The invention relates to the technical field of natural dyes, in particular to a method for dyeing natural dyes (watermelon red). Background technique [0002] Natural dyes are generally derived from plants, animals and minerals, mainly plant dyes. Vegetable dyes are extracted from the roots, stems, leaves and fruits of plants. Such as: indigo, madder, comfrey, safflower, mulberry, tea, etc. The number of animal dyes is small, mainly from shellfish and cochineal, such as: insect (purple) glue, cochineal red, carmine and so on. Mineral dyes are colored inorganic substances extracted from minerals, such as chrome yellow, ultramarine blue, manganese brown, etc. In recent years, it has been found that pigments produced by microorganisms such as bacteria, fungi, and molds can also be used as a source of natural dyes. [0003] In the prior art, dyeing with watermelon natural dyes usually causes uneven dyeing and is not easy to color. Contents of the in...
