As a traditional textile raw material, wool has long been loved by consumers. However, due to the presence of scales and lipids on the surface of the wool fiber, it will cause problems such as felting and poor dyeing effect. With the development of technology and the improvement of people's living standards, the requirements for wool products are getting higher and higher. Wool modification can give wool fibers and fabrics excellent properties. Research on wool modification has gradually become a hot spot.
The surface of graphene oxide has a large number of oxygen-containing functional groups that can form hydrogen bonds or other chemical bonds with other materials. Therefore, graphene oxide is usually used as a reinforcing material in the preparation of composite materials. As a natural fiber, wool cannot be compounded by monomer polymerization or melt spinning. Graphene modified wool composite fiber mainly modifies the surface of wool. After processing the surface of the wool and the graphene sheet layer, the bonding force is strong and not easy to fall off and then the graphene itself is used to give the wool a variety of unique properties.

The main technical route of Alfa Chemistry is to wrap graphene material on the surface of wool fiber. Based on graphene's high electrical conductivity, high thermal conductivity, and large specific surface area and its damaging effect on bacteria, it can give wool extra functions such as antibacterial, electrical conductivity and heating. We have developed a mature graphene wool composite process, which can be used in a variety of woolen clothing, furniture products and other new applications.
Alfa Chemistry hopes to fully develop graphene wool fibers from graphene preparation to graphene fiber composite, and then to the design of large-scale preparation processes and production lines through years of graphene research and experience and ability in developing downstream applications. We strive to achieve a comprehensive approach.
