Abstract

The invention belongs to the field of dye preparation, and particularly relates to a blue dye with a color fixing effect, wherein the blue dye is prepared from the following raw materials in parts byweight: 20 to 30 parts of baphicacanthus cusia bremek, 20 to 40 parts of polygonum tinctorium, 6 to 9 parts of sodium citrate, 5 to 9 parts of simethicone, 5 to 10 parts of a color enhancing liquid, 1part of a color fixing agent and 1 part of a dispersing agent. The blue dye is derived from plants, has the characteristics of safety, no toxicity, economy and environmental protection, and overcomesthe defect that a plant dye is not prone to color fixing through combined use with the color enhancing liquid; the color enhancing, an adhesive and an auxiliary agent are mixed to prepare the color enhancing liquid; when the color enhancing liquid is added into a dye and is used for dyeing, a color enhancing agent is attached to clothes and is tightly combined with the dye, so that the effects ofcoloring and brightening the clothes are achieved, the clothes are not easy to fade and darken after being washed for multiple times, and the clothes can still keep bright and do not fade or darken after being washed with water for multiple times.

Description

technical field [0001] The invention belongs to the field of dye preparation, in particular to a blue dye with color-fixing effect. Background technique [0002] Nowadays, the colors of clothes and cloth are various, and the chemical dyes are also various. Although synthetic dyes have vivid colors, they will decompose and produce toxic substances during use. Moreover, the commonly used chemical dye waste liquids are easy to produce pollution and are not easy to handle. The use of synthetic chemical dyes during use will also decompose and produce toxicity during use, causing harm to people. Therefore, extracting natural dyes from plants is the current direction of preparing dyes. [0003] However, vegetable dyes have the problem of poor color-fixing and color-enhancing effects. For example, Patent No. CN201410591623.0 discloses a plant-based blue dye for cotton cloth, which is prepared by the following method: (1) take 25 parts of fresh horse blue and 30 parts of Polygonum ...
