Abstract

A novel spinning technology is used for spinning zein and fibroin, the spinning technology is simple, an electric field does not need to be used, and the diameter of the prepared nano fiber is much smaller than the diameter of electrostatic spinning fiber and can reach 200-350 nm. Since a silane coupling agent is adopted for grafting of nano titania to a protein chain, aggregation of inorganic particles is avoided, and dispersibility of the inorganic particles is better improved; meanwhile, zinc sulfide and titanium oxide serve as anti-microbial materials, when the zinc sulfide and the titanium oxide are jointly used, the long anti-microbial effect is achieved, the anti-microbial performance can reach 99% or above, good anti-microbial performance is still achieved after washing is conducted 40 times, and the anti-microbial rate can still reach 90% or above.
