Description
Technical field
The wood invention belongs to chemical technology, the mutual interleaving techniques of textile technology field, is specifically related to a kind of nano-TiO
2/ ZnO doping Compound Water colloidal sol and preparation method thereof reaches the method for sorting to fabric.
Background technology
Textiles, because the characteristic (porous and hygroscopicity) of self structure is beneficial to microbial adhesion, makes it become the good parasitic body of microorganism existence, breeding.Can be infected with a lot of sweat, grease, scurf and other various human secretions in the process of people's dress simultaneously or use textiles, also can be polluted by the dirt in environment, these are all the good nutrient sources of various microorganisms.Under hot and humid condition, bacterium and fungi amount reproduction on fiber, finally can produce a lot of problems, especially, after the germ amount reproduction, can to human body, work the mischief by skin, respiratory tract, alimentary canal and blood, causes various illnesss.Can pollute fiber in addition, make that it is mouldy, variable color and smelly, lose wearability.Therefore, antibacterial fabric becomes R&D institution, producer, the main research and development direction of businessman.
At present, a lot of about the report of antibiotic finishing method, the difference according to processing method mainly is divided into: finishing method; Carry out blending modification method at polymerization stage.
The process of finishing method is fairly simple, and processing cost is lower, during current antimicrobial product is produced, in the majority with finishing method.
Blending modification method production process complexity, to antiseptic require highly, and processing cost is higher, so its application is extensive not as finishing method.Antibacterial finishing agent mainly contains: two kinds of organic anti-bacterial finishing agent and inorganic antibacterial finishing agents.
Inorganic antibacterial material is a kind of novel antibacterial material, nano-ZnO, nano-TiO
2deng, ultraviolet ray is generally had to stronger absorption and reflex, there is good photocatalytic activity.And its stable in properties, safety non-toxic, source is abundant.There iing light can be activated by photon under penetrating, realizing that electronics (or hole) flows, and (or reduction) decomposition that in its surface very strong oxidation occurs, can destroy the cell membrane of cell, thereby being run off, cellular component causes bacterium death.The protein of also solidifiable virus, suppress the purpose that virus activity reaches kill virus, has self-cleaning, decontamination, sterilization, deodorizing and remove NO
xthe functions such as pernicious gas.
Great majority research both at home and abroad is all by nano-TiO
2particle is disperseed, and then as finishing agent, fabric is arranged, and these methods have a lot of shortcomings.The first, preparation TiO
2superfine powder needs 300 ℃ of long high-temperature calcinations (>), energy consumption is large, and cost is high; The second, nano material particularly inorganic matter as TiO
2poor with organic textile raw material compatibility, disperse inhomogeneously, easily reunion is even separated out.Therefore need do surface modification to the nano material powder, but the sub-micron-powder particle diameter is little, specific area is large, surface can be high, very easily reunites, even if can not thoroughly solve agglomeration traits through finishing; The 3rd, TiO
2when superfine powder joins spinning solution and prepares functional fibre, mostly be wrapped in fibrous inside, and seldom be exposed to fiber surface, the functions such as it is antistatic, antibacterial and deodouring, automatically cleaning can not be not fully exerted.Even by rear arrangement by TiO
2be coated on fabric, resin binder also can form parcel to it.The 4th, in use, the oxidation-reduction quality that photochemical catalyst is stronger also can impel the premature aging of organic fibrous material itself or adhesive.Simultaneously, sneak into the photochemical catalyst of fibrous inside due to the irradiation that can not fully accept sunshine, also just can not well bring into play photocatalysis.
While finding to adopt sol-gel process to carry out finishing functions to textiles, can avoid many deficiencies of above-mentioned method for sorting in constantly exploring.While adopting sol-gel process to carry out finishing functions to fabric, just its arrangement is formed to gel mould to fabric at sol phase, saved and gel has been become to the step of oxide powder by high temperature sintering, avoid the problem of nano-scale oxide powder autoxidation and reunion, become the new way that nano material arranges fabric functional.
Secondly, when selecting nano-photocatalyst material, seldom adopt method compound, the doping associating to improve TiO
2photocatalysis performance.
