Color-changing fiber belongs to one of various and numerous novel clothing materials, and the appearance of the color-changing fiber is mainly that the color or the pattern of textiles presents different effects along with the changes of illumination, temperature and humidity by means of modern high and new technology. The earliest application of the color-changing fiber is that in 1970, the CYANAMIDE company in the United states developed a fabric capable of changing color after absorbing light in order to meet the functional requirement of better camouflage concealment during war on the battlefield of Vietnam. Various color-changing materials such as embroidery velvet, knitting yarns, woven yarns, etc. have been developed thereafter. And is widely used for sweater, sports shoes, hats, silk stockings and various clothes and dress with decorative leather, and people are also changed from acceptance to favor. The color-changing fiber material brings a lot of changes to the traditional clothing industry, and simultaneously provides a wider creation space for designers.

With the continuous growth of the hair product industry, the proportion of human hair raw materials is smaller and smaller, and human hair resources at home and abroad are gradually reduced. Therefore, the wig industry is highly in need of finding a new human hair resource substitute. The wig is generally divided into animal keratin fiber hair and artificial synthetic wig, wherein the animal keratin wig generally comprises human hair, horsetails, horsehair, yak hair, oxtail and the like, the animal keratin wig has good simulation performance, but the animal keratin fiber has low yield, high price and long growth period, and can not meet a great deal of demands of the market; the synthetic polymer has the characteristics of low price, simple processing, general superior properties of chemical fibers, such as high strength, light weight, easy washing and quick drying, good elasticity, mildew and moth resistance and the like, brings great convenience to human life and has wide application in production.
However, the traditional wig fiber has single color, no activity and relatively dead plate, and can not produce a multi-color effect under light, and the color-changing fiber with partial coloring agent is easy to cause environmental pollution due to the non-environmental protection of the coloring component; the color-changing microcapsule technology can improve the problem, but the problem of thermal stability of the microcapsule and the functional additive in the process of preparing hairline by adopting a melt processing method is more prominent.
