Environment-friendly dyeing agent for textile fabrics and preparation method thereof

Abstract

The invention discloses an environment-friendly dyeing agent for textile fabrics and a preparation method thereof. The environment-friendly dyeing agent is prepared by mixing well a dyestuff and a mordant in the weight ratio of (3.5-4.5):1. Dyeing components of the dyestuff are extracted from dyestuff plants; the dyeing components extracted from the plants have good degrading effect. The mordant is prepared mainly with cerite and tannic acid, is free of heavy metal particles, such as iron, copper and hexavalent chromium, and is more environmentally friendly and better in safety; a nano additive dispersed evenly in the dyeing agent has good ultraviolet resistance and antibacterial property, and fading of the dyestuff after dyeing can be retarded effectively; nano titania and nano zinc oxidehave good color-fixing effect, so that the natural dyestuff has better dyeing effect; in the preparation of the mordant, cerite containing various rare-earth elements can provide good mordanting effect.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing agents, and in particular relates to an environmentally friendly dyeing agent for textile fabrics and a preparation method thereof. Background technique [0002] In the past when technology and technology were underdeveloped, people used plants as raw materials to prepare dyeing agents with dyeing effects. After the British chemists prepared the purple synthetic dye aniline violet in the 19th century, the synthetic dyes were gradually obtained with the characteristics of low cost and stable properties. Widely promoted and used, but with the environmental pollution and the strengthening of people's awareness of environmental protection, people gradually realize that chemically synthesized dyes will cause serious damage and damage to the human body and the environment, so plant dyes have also re-entered people's sight. [0003] Natural dyes are dyes obtained from plants, animals or mineral re...

Problems solved by technology

[0006] 1. In the prior art, the extensive use of synthetic dyes will cause harm to the human body. At the same time, the raw materials of synthetic dyes are mainly fossil raw materials, which cannot be biodegraded and will cause serious damage to the environment. And, degradable and environmentally friendly dyes are one of the problems that need to be solved at present;
