Under the excitation of ultraviolet, the fullerene can generate singlet oxygen or superoxide anion, and has good antiviral and antibacterial capabilities.

Fullerenes have a low water solubility, which greatly limits their applications. CN106519307A discloses a bacterial cellulose/fullerene composite material and a preparation method thereof, wherein fullerene is dispersed and embedded in a three-dimensional nano network of fibers, so that the antibacterial capability of the fibers is endowed, and meanwhile, the defect that the fullerene content in a fullerene water dispersion system is too low is overcome. CN109223828A discloses an application of amino fullerene in preparing antibacterial material and the antibacterial material, wherein the prepared amino fullerene has good water solubility, and the amino fullerene has good antibacterial effect at lower concentration. CN110904522A discloses a fullerene skin-friendly composite fiber and a preparation method thereof. The fullerene is loaded on the fiber after being mixed with the basic fiber and then being mixed with the auxiliary agent and then being subjected to plasma irradiation treatment, so that the fusibility of the auxiliary agent and the fiber is improved, and then the fiber is drawn.

The inventor of the present application discloses a method for preparing an antibacterial fiber cloth by using fullerene in CN 109629073A. The antibacterial polyacrylonitrile fiber, the modal fiber, the bamboo fiber and the polyester fiber are used as raw materials for spinning and weaving, and the antibacterial polyacrylonitrile fiber, the modal fiber, the bamboo fiber and the polyester fiber have better antibacterial performance. In subsequent researches, the wear resistance of the cloth is found to be poor, and the antibacterial performance is gradually reduced along with the increase of the washing times.
