Environmentally-friendly textile dye and method for preparing textile fabric by using textile dye

Abstract

The present invention discloses environmentally-friendly textile dye and a method for preparing textile fabric by using the textile dye. The environmentally-friendly textile dye contains a natural pigment prepared from discarded dragon peels through condensation and reflux extraction, and the natural pigment is compounded with acrylic emulsion and additives containing cationic polymers to form theenvironmentally-friendly textile dye that can be applied to the textile fabric; by extracting the pigment from discarded dragon peels, not only waste resources can be reused, but also a pigment of good quality can be obtained; the pigment is compounded with acrylic emulsion, acetic acid and cationic polymers to achieve high compound stability, and the negative charge on the textile fabric synergistically forms a stable combination; and through the Coulomb gravitational effect, the adhesion strength and wear resistance of natural pigments on the textile fabric can be effectively enhanced, thecoloring rate of dyeing can be improved, and then high-quality uniform coloring effect can be obtained to ensure production quality.

Description

technical field [0001] The invention relates to the field of textiles, in particular to an environmentally friendly textile dye and a method for preparing textile fabrics by utilizing the textile dye. Background technique [0002] Textile dye is a kind of dyeing agent used for textile dyeing. It is divided into natural dyes and synthetic dyes. It contains organic compounds that make fibers dyed into bright and firm colors, so as to perform dyeing on textiles. There is also some research on the dyes extracted from plants in the prior art, but there are still some problems that need to be solved urgently: such as: compared with artificial pigments, plant pigments have poor stability and are susceptible to external factors, such as ultraviolet rays, pH value, temperature, etc.; although pigments extracted from plants have a certain affinity with textiles, their molecules are difficult to penetrate into the interior of textiles and only adsorb on the surface of textiles; pigment...

Problems solved by technology

There is also some research on the dyes extracted from plants in the prior art, but there are still some problems that need to be solved urgently: such as: compared with artificial pigments, plant pigments have poor stability and are susceptible to external factors, such as ultraviolet rays, pH value, temperature, etc.; although pigments extracted from plants have a certain affinity with textiles, their molecules are difficult to penetrate into the interior of textiles and only adsorb on the surface of textiles; pigments and active substances extracted from plant materials are used in textile dyes , the extraction cost of plant pigments is high, leading to high production costs in the textile industry; generally, if chemical blending agents need to be added to plant-extracted dyes, they cannot form a good compound, resulting in poor stability of the dyes, and even uneven dyeing. color block phenomenon

Rosmarinic acid has antibacterial, anti-inflammatory, anti-viral, anti-tumor, anti-allergic, anti-oxidation, anti-thrombotic, anti-platelet aggregation, anti-radiation and immunosuppressive effects, and has good stability, but its preparation cost is relatively high
