Problems solved by technology

However, berberine, which has three needles and acts as a drug in China, is a rare cationic vegetable dye, and the acrylic fabric itself has anionic properties, so the two can be well colored with each other, but the current use of three needles for dyeing In the process, it is necessary to combine three needles as auxiliary raw materials with other plant dyes to prepare dye dyeing; and it is difficult to control the dyeing color chroma by using the existing dyeing process, and the dyed fabric has uneven color, poor fastness and easy to fade, etc. question
After inquiry, so far, there is no relevant report on using the three needles as dyes alone

Abstract

The invention discloses a method for dyeing an acrylic fabric with berberis poiretii schneid plant dye. The method comprises the steps that berberis poiretii schneid is extracted to prepare plant dye,the prepared berberis poiretii schneid plant dye is taken, an appropriate amount of an ammonium acetate or ammonium sulfate retarding agent is added, a dyeing solution is prepared, treatment before soaking is conducted on the acrylic fabric, the treated acrylic fabric is put in the prepared dyeing solution and subjected to three-phase repeated heating and dip-dyeing treatment in a temperature control state, and the dip-dyed acrylic fabric is subjected to mordanting and fixation and aftertreatment. By means of an organic component berberine in the berberis poiretii schneid plant dye and the double retarding agent, under the condition of different control temperatures, the dyeing rates and dyeing degrees for the acrylic fabric are different, a three-phase recycling heating-cooling soaking mode is adopted, the color dyeing progress is effectively controlled, and the acrylic fabric is dyed uniformly with the berberis poiretii schneid plant dye. By means of mordanting and fixation, fixation between the dye and the fabric is more stable, and the acrylic fabric which is uniform in dyeing, good in chromaticity consistence and high in color fastness is obtained.

Description

technical field [0001] The invention relates to the fields of light chemical dyes and printing and dyeing, in particular to a method for dyeing acrylic fabrics with three-needle vegetable dyes. Background technique [0002] At present, in the field of printing and dyeing, especially in the field of clothing washing and dyeing, the pursuit of ecological protection and returning to nature has become a new fashion. People not only pursue the style and effect of ready-made clothing, but also pursue natural ecology, so that people can develop harmoniously with nature. As more and more people pay more attention to their own health, the pursuit of green products and green consumption has become an important demand. Natural dyes are natural, elegant, and have a natural fragrance in the dyed fabrics and clothing. At the same time, they also have certain antibacterial and health care functions. At the same time, natural dyes are derived from nature and are harmless to human health. I...
