Abstract

The invention discloses a method for nanometer ferroferric oxide modification of a chinlon fabric via a hydrothermal process. The method comprises the steps of: first, pre-treating the chinlon fabric; second, directly modifying the fiber surface of the chinlon fabric when preparing magnetic nanometer ferroferric oxide particles via hydrothermal synthesis simultaneously; at last, washing the chinlon fabric by a washing liquid at a bath ratio of 1:(30-50) at 70-90 DEG C for 10-30 minutes, then washing the chinlon fabric repeatedly by hot water at 80 DEG C and cold water, drying the chinlon fabric, and then finishing nanometer ferroferric oxide modification of the chinlon fabric. The modification method disclosed by the invention saves raw materials, is simple to operate and has good washingfastness. The test result proves that the chinlon fabric obtained after the magnetic nanometer ferroferric oxide is modified still has excellent magnetic performance after thirty times of standard washing.
