Background technology
Titanium dioxide, chemical formula TiO
2it is a kind of polymorphous semiconductor material with wide forbidden band, the performance shown in photocatalytic water, photochemical catalytic oxidation, photo catalytic reduction, photocatalysis synthesis of organic substance, photocatalysis to degrade organic matter, sterilizing, solar cell, automatically cleaning, gas sensor and humidity sensor etc. is noticeable, has important application prospect.Current TiO
2power production is industrialization, but TiO
2powder also exists the shortcoming of application aspect, such as: due to nano-TiO
2particle is trickleer, is easy to cohesion, not free settling in aqueous and is difficult to reclaim, not only bad for regeneration and the recycling of product, also can cause the secondary pollution of water body.Therefore, people tend to prepare the nano-TiO with high catalytic activity gradually in recent years
2film.At present, achieved prepared nano-TiO in the inorganic substrates such as copper mesh, glass, sheet metal
2film.TiO in the flexible substrates such as polymer
2the growth of film, can expand its Application Areas further.Be that substrate deposition grows TiO with polymer
2some performances of polymer can also be improved, such as, hydrophily, antibiotic property and ultra-violet resistance energy etc.
By TiO
2combine with textile material, can produce and there is ultra-violet resistance energy, the multi-functional textiles of anti-microbial property and self-cleaning performance.In addition, because the hole of textiles is adjustable, also can be used for sewage water filtration and degraded.At present, TiO is utilized
2it is by TiO that the method for carrying out functional modification to artificial fibre mainly contains two kinds: one
2nanoparticle dispersion is in spinning solution, and direct fabrics are shaping; Two is by TiO by coupling agent or other electric charge finishing agents, auxiliary agent
2nano particle slurry is coated in fiber surface film forming or preparation TiO
2nanoparticle dispersion liquid by the method for padding in fiber surface film forming.Such as, patent CN101718035A discloses with sodium acrylate and ethanol as TiO prepared by solvent
2nanoparticle dispersion liquid, then after padding on terylene non-weaving cloth, obtain the dacron with self-cleaning function.The shortcoming of first method is TiO
2nano particle is nearly all embedded in the fibre, the TiO that fiber surface exposes
2nano particle is few, thus little to the functional modification effect of fiber itself.The shortcoming of second method is the TiO of fiber surface after treatment
2the binding strength of film and fiber is not good, and the film on surface is TiO
2film of nanoparticles, granularity is uneven, and skewness, photocatalytic activity is not as having the TiO of one-dimensional nano structure
2film, as uniform TiO
2nano-wire array film and TiO
2nano flower array film etc.
Compare load TiO
2nano particle, load TiO on fabric
2nano-wire array can the self-cleaning function of significant increase fabric and anti-microbial property.At present, load one dimension TiO on dacron
2nano-wire array there is no bibliographical information.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, one load TiO on dacron is provided
2the method of nano wire.Compared to existing terylene and TiO
2compound prepares the technology of functional fabric, and the technology of the present invention significantly can promote self-cleaning performance (photocatalysis performance) and the anti-microbial property of fabric.
