With the improvement of living standard of people, wig products are increasingly popular, while the raw material hair for manufacturing wig in the market at present is mostly chemical synthetic fiber, and because the raw material hair is not limited by resources, the wig has been industrially generated, the cost is low, and the price is low, so the wig becomes the mainstream of the hair product market. The synthetic fibers commonly used in wigs include PVC fibers, polyacrylonitrile fibers, polyester fibers, polypropylene-based fibers, protein fibers and the like, and although the synthetic fibers have good elasticity, smoothness and bright color, the synthetic fibers have poor skin-friendly property, air permeability and moisture absorption, and have great difference with natural human hair. In addition, most of the synthetic fibers are petrochemical products and are non-renewable resources, and are difficult to degrade and pollute the environment when being discarded in the environment, so that the requirements of people on green environment cannot be met, therefore, the research direction of wig raw materials is mainly to extract the fibers from the renewable resources to prepare the wig, and the prepared wig has the texture and quality similar to real hair.
Keratin is a renewable biological protein with abundant natural reserves, widely exists in hairiness of birds and poultry and hair of people and livestock, and has potential application in the fields of biological medicine, textile printing and dyeing, food processing, environmental protection and the like. However, pure keratin fibers have low strength, high brittleness, poor flame retardancy and low practical value. Therefore, a series of keratin composite fibers are provided, namely, the keratin and other fiber-forming polymers are dissolved in a cosolvent, and the composite fibers with certain mechanical properties and elongation at break and practical value are prepared by spinning processes such as a wet method, a dry spraying wet method and the like.

With the increasing demand of wigs, people begin to consider the aspect of easy cleaning and stain resistance, and hope that the wig material is easy to clean and not easy to stain, so that the service life of the wig material can be prolonged.
