Problems solved by technology

However, in the process of processing, nanomaterials are easy to agglomerate, nanomaterials are unevenly distributed on the surface of fibers and fabrics, and the combination of nanomaterials and fibers is low (Zhou Shunli, Wang Feng, Xiong Zujiang, Wang Rui, Yang Chunfang, Zhang Xiuqin, Yang Mingshu .Research progress on photocatalytic self-cleaning fabrics based on nano-TiO2[J]. Polymer Bulletin, 2017,(04):9-18)

Abstract

The invention discloses a washing-resistant nano-titanium dioxide modified cellulose fiber and a preparation method thereof. Nano-titanium dioxide particles are generated in situ in the cellulose fiber, and the middle of BSA is coated with the nano-titanium dioxide particles, so that the adhesion capacity of the nano-titanium dioxide particles is greatly improved. After being modified by virtue ofthe nano-titanium dioxide particles, the cellulose fiber has excellent antibacterial property, ultraviolet resistance, photocatalysis performance, super-hydrophobic property, wrinkle resistance, washing resistance and self-cleaning property.

Description

technical field [0001] The invention relates to a nano-titanium dioxide modified cellulose fiber with washability and a preparation method thereof, belonging to the field of functional nanometer materials and textile materials. Background technique [0002] Since the 1990s, with the improvement of measurement and characterization techniques, nanomaterials and nanotechnology have developed rapidly. Nanomaterials refer to materials with a size of 1-100nm. Different from bulk materials, they have unique optoelectronic properties and have been widely studied and applied in various fields such as electronics, materials, medicine, biology, machinery, textiles, printing and dyeing. As far as the textile field is concerned, the combination of nanomaterials and textiles can effectively improve the inherent defects of textiles, expand the scope of application of textiles, and increase the added value of textiles. A large number of research results have shown that the use of titanium ...
