Nano-TiO2 has attracted much attention due to the advantages of cheap and non -toxic, small particle size, large surface area, high catalytic activity, good absorption performance, strong absorption of ultraviolet capacity, large surface activity, and good stability. At present, TIO2 mainly has the advantages of anti -ultraviolet, antibacterial, anti -static, anti -static, anti -aging, and self -cleaning.
1. Anti -ultraviolet rays
Nano -TiO2 is widely used as anti -ultraviolet absorbers to synthetic fiber fabrics such as polyester, natural fiber cotton fabrics and composite materials. There are experiments to use nano -TiO2 to organize polyester fabrics. The fabric has a good anti -ultraviolet absorption performance, has a good washing resistance, and has a small impact on the rigidity, breathability and strength of the fabric.
2. Antibacterial performance
TIO2 is widely used in textiles as a new type of inorganic antibacterial agent. Its antibacterial performance is widely speined, durable, and safe, and its optical chemical stability is excellent, non -toxic and cheap.
The nano -level TIO2 particles have strong antibacterial properties under the light, and with the increase of antibacterial concentration and light time, the antibacterial rate is increased, and the antibacterial effect is significantly strengthened. It is feasible to treat the nano -TiO2 on the fabric with the soaking method, and the processed fabric has obvious antibacteriality, but the adhesive and dispersant need to be added to improve the combination of TIO2 and fabric. After adding adhesives and dispersing agents, the antibacteriality of the fabric has good water -resistant performance.
3.Anti -static performance
Plants’ anti -static electricity consolidation is to quickly transmit and consume the charge through the conductive of the material, so as to achieve the effect of anticidering. At present, the nano -materials in textiles are mainly TIO2, Zno, graphene, etc.
4. Extraction performance
Add nano TiO2 to chemical fibers, and chemical fibers can be gone. At present, TIO2 is mainly used in polyester fibers as a elimination agent, and has extremely high opaque. The chemical properties are stable, the heat resistance is good, and it is easy to disperse in the original liquid and fiber. It does not affect the strength of the fiber and after the fiber is processed after the light.
5.Anti -aging performance
Many chemical fiber textiles will cause degradation of molecular chain under ultraviolet rays, generating a large amount of free radicals, which greatly affects the color and strength of the textiles. Studies have shown the effects of golden stone nano -titanium dioxide and other effects on the aging performance of high -density polyethylene (HDPE)/wood fiber composite materials. Test results: Nano -titanium dioxide can play a significant anti -aging effect on composite materials.
6. Self -cleaning performance
Nano -TiO2 is stimulated by ultraviolet rays, with strong photocatalytic performance and can oxidize and degrade dirt. Researchers have found that the special interface formed by TIO2 nano -particle sprayed on the material can make the surface of the material present the extraordinary double sparse (hydrophobic and oil). Various textile fabrics processed showed excellent water and oil -refusted. The original physical and chemical properties of fibers such as fiber strength, affinity of dyes, and breath-ability of the fiber have no effect.
