Preparation and Application of Modified Nano-titanium Dioxide Agent

摘要

Cotton is the most widely used fiber. However, cotton fabric has a relatively high UV radiation permeability. Compared with some synthetic fabrics, cotton fabrics anti-UV ability is lower. Nano-titanium dioxide has a good catalytic and ultraviolet light shielding effect, so it can be used as anti UV finishing agent. Using modified nano-titanium dioxide to finish the cotton fabrics, one can get the function of anti-UV performance. Therefore, in this paper, nano-titanium dioxide was first modified with 1,6-hexamethylene diisocyanate and polyethylene glycol in order to improve their size stability. And then by way of finishing, the modified nano-titanium dioxide dispersion was soaked into cotton fiber. During a baking process, modified nano-titanium dioxide was combined with cotton fibers via covalent bonds.
