Abstract

The invention provides an antibacterial polyester fiber based on silver-loaded zirconium phosphate and a preparation method thereof. The antibacterial polyester fiber based on the silver-loaded zirconium phosphate is characterized in that the fiber comprises a polyester matrix, and silver-loaded zirconium phosphate powder is dispersed in the polyester matrix. The preparation method includes the steps that silver-loaded zirconium phosphate nano-powder is prepared; the silver-loaded zirconium phosphate nano-powder, terephthalic acid and dihydric alcohol are added into a polyester reaction still, silver-loaded zirconium phosphate antibacterial polyester is prepared through in-situ polymerization, and the antibacterial polyester fiber based on the silver-loaded zirconium phosphate is prepared by means of melt direct spinning; or the silver-loaded zirconium phosphate antibacterial polyester is pelleted, so that a silver-loaded zirconium phosphate antibacterial polyester master batch is obtained, and the antibacterial polyester fiber based on the silver-loaded zirconium phosphate is prepared through a master batch blended spinning method. The antibacterial polyester fiber prepared through the method has the advantages of being efficient and lasting in antibacterial action.
