Sterilizing red scarf

The utility model discloses a bactericidal red scarf, comprising a main body which comprises a bactericidal cloth layer; the bactericidal cloth layer includes a cotton fibre layer woven from cotton fibre; the outer surface of the cotton fibre layer is coated with a sulfonated polymer layer; the cotton fiber of the cotton fibre layer is perforated, and the outer surfaces of the cotton fiber and the holes are coated with sulfonated polymer layers. The outer surface of the cotton fibre of the bactericidal red scarf is coated with the sulfonated polymer layer, and the cotton fabric is processed with industrial javelle; sulfonated polymer has nitrogen-hydrogen bonds which can have replacement reaction with the chloridions in the industrial javelle, thus providing the sulfonated polymer with nitrogen-chlorine bonds which cling to the cotton fabric; since the chloridions are of bactericidal function, the bactericidal red scarf can effectively kill harmful bacteria and virus clinging to or growing on the red scarf.
