Abstract

The invention discloses a method for catalyzing the modification of polyester fibers, which is specifically implemented according to the following steps: step 1, soaking the polyester fibers in a sodium hydroxide solution for etching, and then cleaning and drying the etched polyester fibers ; Step 2, configuring a modified solution, and using the modified solution to modify the etched polyester fiber; Step 3, cleaning and drying the modified polyester fiber. The method of the invention realizes directly loading metal ions on the surface of the polyester fiber and doping the anatase phase nano-titanium dioxide film. The modified polyester fiber not only has good photocatalytic efficiency, expands the spectral response range, but also improves the performance of the polyester fiber. Self-cleaning ability.

Description

technical field [0001] The invention belongs to the field of fiber manufacturing, and in particular relates to a method for catalyzing the modification of polyester fibers. Background technique [0002] Nano-titanium dioxide is a functional fine inorganic nano-material with high added value that has developed rapidly in recent years. It has small particle size, large specific surface area, high surface activity, good thermal conductivity, good weather resistance and chemical corrosion resistance. And other advantages, its unique ultraviolet shielding ability, photocatalytic activity and color effect make it very popular once it comes out, widely used in antibacterial, wastewater treatment, catalysis and automotive industries and other fields. When used as a photocatalyst to degrade sewage, anatase phase nano-titanium dioxide has the advantages of non-toxicity, high stability, low preparation cost, no secondary pollution and wide application of pollutants, etc., and has been ...
