With the rapid development of science and technology, the life of materials is greatly enriched, the fast-paced life style and the continuously increased working pressure of modern people are accompanied, people pay more and more attention to the health and living environment of the people when pursuing the abundance of materials, and the people begin to desire to return to the nature. The requirements of the clothes are not only basic living requirements of body shading, cold protection and the like, but also more attention is paid to comfort and leisure, and the characteristics of the green textile fiber just meet the potential requirements of people. The development trend is fully reflected by the popularity of pure cotton, hemp, silk and wool products in recent years and the strong advocation of green ecological textiles in international organizations and countries. Therefore, cotton, hemp, silk and wool are regarded as four natural fibers in the traditional sense by human beings again. The natural fiber clothing fabric is relatively common in hue appearance, usually needs to be dyed to improve ornamental value and value, is limited by characteristics of the natural fiber clothing fabric, has relatively poor coloring performance during dyeing treatment, is easy to fade, has insufficient use stability, and needs to be continuously improved.
Most dyestuff is chemical dye at present, and synthetic dye is lifelike although the colour, can produce in the dyestuff use and decompose, produces the noxious material, and chemical dye waste liquid etc. commonly used now easily produce the pollution moreover, and difficult processing uses synthetic chemical dye also can produce in the use and decompose and produce the toxicity in the use, causes the injury to the people.

Note: the breaking strength described in table 1 above was measured using a YG020A type electronic single yarn strength tester, the drawing speed was controlled at 215mm/min, the ambient temperature was 22 ℃, the humidity was 70%, and the pre-tension was 0.07 cN/dtex; the dye-uptake is the measured dye-uptake of reactive blue 220 dye; the washing resistance grade adopts ISO105C 06: 1994+ Corl: 2002, machine washing at 25 deg.C, air drying, and determining the water-washing resistance grade.
As can be seen from the results in Table 1, the dye uptake of comparative example 1 is slightly higher than that of the examples in this document, but the breaking strength and the washing resistance are slightly lower, which shows that the dye and the dyeing method in this document have the advantages of high dye uptake and the effect of enhancing the fiber strength.
