Description

technical field [0001] The invention belongs to the field of preparation of low-dimensional nano material films, in particular to a preparation method of zinc oxide nanorod films on fiber products. Background technique [0002] In recent years, with the improvement of people's living standards, people's requirements for clothing are getting higher and higher. High-grade, comfortable textiles with anti-ultraviolet, antibacterial, self-cleaning and other functions are more and more favored by consumers. ZnO is a multifunctional semiconductor material with excellent shielding and protection against ultraviolet rays. When the particle size of these materials is comparable to that of light waves or smaller, the light absorption is significantly enhanced due to the small size effect. Therefore, zinc oxide nanopowder can attenuate ultraviolet rays, especially ultraviolet rays with a wavelength of 280nm-320nm; at the same time, nano-zinc oxide particles have better visible light t...

Problems solved by technology

[0004] But above-mentioned these two kinds of methods all must at first prepare ZnO ultrafine powder, the preparation process of nanoscale ultrafine powder is complicated, and preparation process needs high-temperature treatment, and energy consumption is high, and cost is high; The surface energy is very large, it is very easy to aggregate, and the original superior properties of nanoparticles are lost. Although the surface modification of nano-zinc oxide by esterification reaction method, surface coupling grafting method or radiation grafting method can effectively solve the above problems It must be improved, but it cannot fundamentally solve the above-mentioned problems of ultrafine powders. The phenomenon of agglomeration of ultrafine powders after modification still exists, and the cost increases; Inside, the powder cannot be in contact with oxygen and moisture, photocatalysis cannot occur, and its antibacterial and deodorizing functions cannot be exerted. Using this method requires high equipment requirements

If the superfine powder is agglomerated, there are larger aggregates, which may block the spinneret, and it cannot be processed such as cotton, hemp, silk, wool and other natural textiles; if the second method is used, that is, the post-finishing method , when the powder is added to the textile, the powder will be unevenly distributed due to the action of the binder

Moreover, the adhesive will cover the powder so that it cannot be in contact with oxygen and moisture, the photocatalysis cannot occur, and its antibacterial, deodorizing and other functions cannot be exerted.

In addition, the post-finishing process using adhesives will affect the fabric's feel, strength, elasticity and other properties, and the washing fastness and functional durability of the processed functional fabrics are also very poor.
