Abstract

The invention discloses a method for modifying a polyester fabric by using magnetic nanometer iron oxide. The method comprises the following steps of: preparing a sodium hydroxide solution; pretreating the polyester fabric by using the sodium hydroxide solution; then cleaning and drying the pretreated polyester fabric; then preparing a modified solution containing ferrous sulfate, sodium hydroxide, nickel sulfate, cetyl trimethyl ammonium bromide and chitosan; putting the pretreated polyester fabric into the modified solution for hydrothermal reaction to acquire a modified polyester fabric; and finally preparing a coupling agent solution, putting the modified polyester fabric into the coupling agent solution, and then solidifying the modified polyester fabric treated by the coupling agent solution so as to finish the modification of the polyester fabric by using the magnetic nanometer iron oxide. According to the method, the problems of no magnetism or poor magnetism, nondurable cleaning performance and poor hand feeling and gas permeability of common polyester fabrics are solved.

Description
