Abstract

The invention discloses a method for preparing a magnetic nano ferroferric oxide particle thin film on the surface of a chinlon fabric. The method comprises the following steps of: firstly, pre-treating the chinlon fabric; secondly, while magnetic nano ferroferric oxide particles are prepared, directly modifying the surface of chinlon fabric fibers; and finally, washing the chinlon fabric with a detergent for 10 to 60 min at the bath ratio of 1:30-50 and at the temperature of between 70 and 90 DEG C, repeatedly washing the chinlon fabric with 80 DEG C hot water and cold water, and airing the chinlon fabric to prepare the magnetic nano ferroferric oxide particle thin film on the surface of the chinlon fabric. By the method for preparing the magnetic nano ferroferric oxide particle thin film on the surface of the chinlon fabric, raw materials are saved; the operation is simple and convenient; and the washing resistance is high. After the magnetic nano ferroferric oxide modified chinlon fabric is subjected to standard washing for 30 times, the fabric still has excellent magnetic performance.
