Environmentally friendly dye composition

Abstract

The invention discloses an environmentally friendly dye composition which comprises the components of a natural dye, a natural mordant, a cationic color fixing agent, a compound natural color fixing agent, an amino silicone softener, sea salt and natural diatomaceous earth. The added natural mordant is not only environmentally friendly, but also improves the dye uptake rate of the dye; the cationic color fixing agent can form a stable color lake with the dye to prevent the dye from detaching and hydrolyzing due to ionization; and the natural color fixing agent can be crosslinked with the dye to form a membrane, so that the dye is not easy to fall off, and a good color fixing role can be played; the added amino silicone softener can not only improve the softness and smoothness of an embroidery thread, but also forms a film with a poor water absorption performance to further play a color fixing and protecting effect, the components work together to allow the dye composition to have the advantages of environmental protection, high dye uptake rate and high color fixation rate, and the phenomenon of desorption of the dye can effectively reduced, and the problem that the dye is easy to fade when meeting water can be improved.

Description

technical field [0001] The invention relates to the field of dyes, in particular to an environment-friendly dye composition. Background technique [0002] With the strengthening of people's awareness of environmental protection and the sustainable development strategy has become the theme of economic development in all countries in the world, and environmental and ecological protection is an important part of the implementation of sustainable development in various countries. Actively respond to the research and development of dyes and additives, not only carry out the research and development of clean production technology and green production technology in a targeted manner, continuously improve the environmental and ecological protection quality indicators of existing dyes and auxiliaries, but also put the development of new environmentally friendly dyes and auxiliaries To a prominent position in the development of my country's dyestuff industry, and with the continuous exp...

[0003] Chinese Patent No. CN201410799295.3 discloses a preparation method of vegetable dyes and embroidery thread of Hunan embroidery, mainly by extracting plant pigments as direct dyes, although it can meet the requirements for environmental protection, but the dyes have low adhesion and will be damaged when exposed to water. Discoloration of pigments

Chinese Patent No. CN201210084639.3 discloses a neutral dye composition, which is composed of a dye component and an auxiliary component. The dye composition is used in combination with three dyes to obtain better homochromaticity. However, the use of additives is monotonous and cannot improve the color fixation rate very wel
