Problems solved by technology

Fourth, during use, the strong redox property of the photocatalyst will also promote the premature aging of the organic fiber material itself or the adhesive
At the same time, the photocatalyst mixed into the fiber cannot fully play the photocatalytic effect because it cannot fully receive the sunlight.

Abstract

The invention belongs to the technical field of intersection of a chemical technology and a textile technology, and particularly relates to a nano TiO2 / ZnO-doped composite hydrosol, and a preparation method of the nano TiO2 / ZnO-doped composite hydrosol and a finishing method of a textile. The composite hydrosol comprises the following components: ZnO hydrosol, TiO2 hydrosol, and Ag<+> or La<3+> of which the mass percent is 0.1-1%, wherein the quantity ratio of the TiO2 hydrosol to the ZnO hydrosol is 1:(0-5), namely TiO2, ZnO and La<3+> or Ag<+> are compounded in nanoscale at a sol dissolving stage by a sol-gel method; the doped hydrosol containing a plurality of components is prepared on the same transparent medium; the prepared doped hydrosol is used for functional finishing of the textile; an organic solvent is removed in a baking manner; a layer of oxide gel mask with a porous structure is formed at the surface of the textile; better irregular tightness is directly formed by the oxide gel mask and the fiber surface; the multi-functionality of the textile is endowed.

Description

technical field [0001] The wood invention belongs to the intercrossing technical field of chemical technology and textile technology, and specifically relates to a nano-TiO 2 / ZnO doped composite hydrosol and its preparation method and fabric finishing method. Background technique [0002] Due to the characteristics of its own structure (porosity and hygroscopicity), textiles are conducive to the attachment of microorganisms, making them good parasites for the survival and reproduction of microorganisms. At the same time, when people wear or use textiles, they will be contaminated with a lot of sweat, grease, dander and other human secretions, and will also be polluted by dirt in the environment. These are good sources of nutrition for various microorganisms. Under high-temperature and high-humidity conditions, bacteria and fungi proliferate on fibers, which will eventually cause many problems, especially after the bacteria proliferate, they will cause harm to the human bod...
