Problems solved by technology

[0002] Bamboo fiber fabric is widely used in skin-friendly products such as clothing, bedding, towel because of having natural antibacterial, antibacterial and anti-ultraviolet effect, mainly adopts chemical dyeing method to dye bamboo fiber fabric at present, as publication number is CN101935930A (open No. 2011-01-05), the method adopts pickling in the pretreatment process to greatly color the environmental pollution, and because bamboo fiber fabrics are usually made into skin-friendly products, the bamboo fiber treated with chemical dyeing method The fabric is not guaranteed to be safe for people to use
Along with the improvement of people's quality of life, more and more researchers begin to try to carry out coloring with natural dyestuff, as the Chinese patent that publication number is CN201210384097.1 uses tealeaves to be used for the dyeing of bamboo fiber fabric, and this method passes through Mordant dyeing, in the secondary dyeing, lime and ethylenediaminetetraacetic acid are chemical reagents used in the mordant dyeing process, which cannot achieve natural and environmentally friendly effects, and chemical reagents have a certain impact on the quality of bamboo fiber fabrics

Abstract

The invention relates to a dyeing method of a bamboo fiber bath towel, and especially relates to a dyeing method of an environmentally-friendly bamboo fiber bath towel. The method comprises the following steps: 1, extracting a plant color fixing agent; 2, drying the plant color fixing agent; 3, extracting a plant dyeing agent; 4, pre-processing; 5, carrying out primary color fixation; 5, dyeing; 7, carrying out secondary color fixation; and 8, dehydrating, and drying. Primary color fixation, dyeing and secondary color fixation are combined to dye the bamboo fiber bath towel, so the process is simple, the color is fastened, and a color fixation solution can be repeatedly used to save the cost; the above ultrasonic dyeing method realizes fast and uniform dyeing and softens the bamboo fiber bath towel; and plant extract products are adopted as the color fixation agent and the dyeing agent, have the characteristics of no heavy metal ions, natural plants, environmentally-friendly dyeing, weed removal, production facilitation and low cost, can clear heat, detoxify and prevent bacteria, and has a very good protection effect on skins.
