Technical Field

Ultraviolet radiation is electromagnetic radiation having a wavelength shorter than visible light but longer than the X-ray, ranging from 10 nm to 400 nm, and having an energy from 3 ev to 124 ev. Its name is that the electromagnetic wave frequency in the spectrum is higher than the purple visible to the naked eye, also known as ultraviolet light. The main ultraviolet light source in nature is the sun, and when sunlight penetrates the atmosphere, ultraviolet rays with the wavelength shorter than 290 nanometers are absorbed by ozone in the atmosphere. With the development of human society, the ozone layer on the earth surface has become seriously empty, and the ozone concentration of the ozone layer is reduced, so that the ultraviolet radiation quantity of the sun to the earth surface is increased, and the normal survival of human beings and other organic organisms is influenced. Ultraviolet light has been identified as being associated with the development of many diseases. For example: wrinkles, sunburn, cataracts, skin cancer, visual impairment and damage to the immune system.
The nano ceramic material is a nano material with the grain size of 1 to 100 nanometers and chemical components belonging to inorganic nonmetal, and the nano ceramic powder is a most basic nano ceramic material. The nano ceramic composite functional fiber prepared by compounding and doping the nano ceramic powder with special performance and other polymer materials not only has the conventional characteristics of common fibers, but also has the special functional characteristics of nano ceramic materials.
At present, in the field of textile material technology, there have been various attempts to achieve protection against ultraviolet radiation by combining nanomaterial technology. For example, xiamen Huapu high technology industry limited company has developed a series of novel nano ceramic cotton textiles with functions of silver plating, antibiosis, far infrared, ultraviolet resistance and the like, has good health care function and high washing fastness, and has formed large-scale production and processing capability. However, as for nylon materials, there is no mature technology for combining with nano-ceramics to provide ultraviolet radiation protection, and researchers are urgently needed to actively develop and expand the application range of nylon materials.

TABLE 1
As can be seen from Table 1, the new high-performance nano ceramic ultraviolet-proof nylon material obtained by the preparation method has a remarkable effect on ultraviolet ray UVA and UVB radiation prevention no matter before water washing or after water washing for multiple times. The modified nano ceramic of the invention is lack of the comparative nylon material 1 which only uses common nano ceramic powder, and has no difference with common fabrics in the aspect of ultraviolet protection effect; and the fiber material prepared by compounding polytetrafluoroethylene, methyl methacrylate, poly-silicon nitrogen resin and nylon fiber only uses the pure nylon fiber, although the ultraviolet protection effect is very obvious compared with that of the nylon material 2 before washing, the effect is obviously reduced after washing for many times, and the service life is limited. Therefore, the novel high-performance nano-ceramic ultraviolet-proof nylon material achieves the expected purpose of the invention and has further popularization and application values.
