Dyeing production method of plant dye with natural bacteriostatic function

Abstract

The invention relates to a dyeing production method of a plant dye with a natural bacteriostatic function. The dyeing production method comprises the steps that the crudely extracted Chinese herbal medicine plant pigments are utilized, a plant dyeing method without water drainage is used for dyeing, and the color is fixed by a natural color fixing agent after dyeing; a fabric or cloth is put intoultrasonic dyeing equipment filled with plant dye liquid, and the ultrasonic waves are started to intermittently dip-dye; a cylinder-refilling dyeing method is adopted, and the liquid is not drained after dyeing each time; the natural color fixing agent is used for fixing the color. The dyeing production method has the advantage that the crudely extracted natural plant dyes are adopted, and are matched with the natural color fixing agent, the cylinder-refilling dyeing processing without water drainage is performed on the clothes and fabrics, such as cotton, hemp fiber, viscose, Tencel and Modal, by the ultrasonic waves and the dyeing liquid is not drained in the dyeing process each time, so that the natural plant dyes and the natural color fixing agent can be effectively utilized, the water resource is greatly saved, the sewage treatment process is not required, and the natural bacteriostatic property of the product dyed by the plant dyes is effectively guaranteed.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing, and in particular relates to a plant dyeing production method with natural antibacterial function. Background technique [0002] Antibacterial textiles are high-end functional textiles. The current antibacterial processing mostly uses chemical antibacterial agents and heavy metals such as nano-silver, nano-zinc, and nano-copper. Chemical antibacterial agents only target germs, and have very weak effects on fungi and viruses. Chemical antibacterial agents can also produce drug resistance, resulting in a decline in the function of the human immune system and harmful effects on the normal human body. The broad-spectrum antibacterial effect of heavy metals such as nano-silver, nano-zinc, and nano-copper is very good. While killing germs, it also kills all probiotics on the surface of the human skin, which is more harmful to the normal human body, and nano-silver, nano-zinc Heavy metals suc...

Problems solved by technology

[0005] The vegetable dye dyeing of clothing and fabrics at home and abroad is mainly manual dyeing, inheriting the traditional craft, and adopts the method of multi-pass dyeing, drying, and washing. Due to the low coloring rate of vegetable dyes, a large amount of water is required for washing, so The manual plant dyeing process is a water-consuming process, and the manual plant dyeing is mostly produced in small workshops, without environmental protection facilities, and the washing wastewater after dyeing is directly discharged, which is not a sustainable and environmentally friendly production method

[0006] Chinese patent application number: CN200810001104.9, discloses an ultrasonic dyeing and finishing washing process, which is mainly applied to the continuous washing method of fabrics dyed with chemical dyes of woven fabrics, which only improves the washing effect and has no effect on sewage discharge

Chinese patent application number: CN201010542393.0, discloses an ultrasonic dyeing method, which is used for high-temperature dyeing of chemical dyes, not suitable for dyeing of vegetable dyes
