Abstract

The invention discloses a nanometer titanium dioxide cotton fiber modifying method with improved dyeing property and attachment firmness. The nanometer titanium dioxide cotton fiber modifying method comprises the following specific steps of: firstly, carrying out pretreatment on cotton fibers; secondly, configuring a modifying solution and carrying out modifying treatment on the cotton fibers by adopting a hydro-thermal method; and thirdly, carrying out post treatment on the modified cotton fibers. According to the nanometer titanium dioxide cotton fiber modifying method disclosed by the invention, the problems of poor dyeing properties of the nanometer titanium dioxide coated cotton fibers and low attachment firmness of nanometer titanium dioxide and cotton fibers are solved and the cotton fibers are endowed with the performances of ultraviolet resistance and bacteria resistance.

Description

technical field [0001] The invention belongs to the technical field of functional textile materials, and relates to a method for modifying the surface of cotton fibers, in particular to a method for modifying nano-titanium dioxide cotton fibers for improving dyeing performance and adhesion fastness. Background technique [0002] Nano-titanium dioxide has high photocatalytic activity, good heat resistance and chemical corrosion resistance, and can be used as a catalyst and its carrier, nano-sensitive materials and nano-ceramic functional materials. Nano-titanium dioxide particles are prone to agglomeration, resulting in a significant reduction in photocatalytic activity. Therefore, the synthesis of monodisperse, high-quality nano-TiO2 has become the focus of people's research. At present, the methods for preparing nano-titanium dioxide mainly include sol-gel method, uniform precipitation method, microemulsion method and hydrothermal method, etc. Among them, hydrothermal tech...
