Abstract

The invention discloses anti-fog and haze fiber with a photocatalytic effect and a preparation method thereof, and relates to the field of air purification. The size of the anti-fog and haze fiber with the photocatalytic effect is 300 to 800 nm. Te preparation method of the anti-fog and haze fiber comprises the following steps: (1) preparing titanium dioxide sol, adding a graphene solution in thetitanium dioxide sol, and uniformly stirring; (2) dissolving a polymer in an organic solvent, magnetically stirring, adding a mixed solution obtained in step (1), a silane coupling agent and a hyperdispersant in sequence, then carrying out ultrasonic dispersion for a certain time, thus obtaining a uniformly mixed spinning solution in certain concentration; (3) adding the spinning solution obtainedin step (2) in a spinning container, extruding the spinning solution from a spinneret orifice through an injection pump, drafting under the propelling of high-speed airflow and the action of thermalradiation, and volatilizing a solvent, thus forming the anti-fog and haze fiber with the photocatalytic effect. A test verifies that the obtained anti-fog and haze fiber has excellent fog and haze resistance and an excellent antibacterial effect.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an anti-smog fiber with photocatalytic effect and a preparation method thereof. Background technique [0002] Smog is common in cities. The economic and social activities of high-density population will inevitably bring a large amount of fine particulate matter (such as PM2.5). Once the emission exceeds the circulation capacity of the atmosphere, it is prone to large-scale smog due to the influence of calm weather. . The existing anti-smog fiber has low filtering effect and is easy to become a carrier for bacterial growth. [0003] Solution jet spinning, as an emerging spinning technology, has broad application prospects in the preparation of nanofibers. It uses high-speed airflow as the driving force. After the polymer solution is extruded through the spinneret holes, it is driven by high-speed airflow. The polymer jet is formed under the process of reaching the receiving devic...
