The principle of the invention is that various metal ions have antibacterial effect, and the intensity of sterilization and pathogen inhibition of the metal ions has the following rules: ag, Hg, Cu, Cd, Cr, Ni, Pb, Co, Zn and Fe. Experiments prove that Hg, Cd, Cr and Pb have residual toxicity to human bodies, and Ni, Co and Cu ions have a dyeing effect on objects, so that the Hg, Cd, Cr and Pb are not suitable for being applied to chemical fibers. Therefore, metal antibacterial agents for chemical fibers belong to Ag, Zn and compounds thereof. Photocatalytic bactericides such as nano titanium dioxide and nano zinc oxide generally show performance superior to that of traditional antibacterial agents. The photocatalytic bactericide is confirmed to be capable of effectively killing the following bacteria: coliform bacteria, pseudomonas aeruginosa, flavococcus and the like. For nano semiconductor, when the particle is thinned to nano scale, the oxidation reduction capability of photo-generated electrons and holes is enhanced, when the nano semiconductor is irradiated by sunlight and ultraviolet rays, antibacterial agents such as nano titanium dioxide and nano zinc oxide can be automatically decomposed in a system with moisture and air, free moving electrons (e-) are released, and positively charged holes (h +) are left, and the main reaction is as follows:
the resulting hydroxyl-bearing free radical OH and superoxide anion radical O2 -All the components are very active and have extremely strong chemical activity, and can react with various organic matters (including organic matters in bacteria and secreted toxins), so that the bacteria, the remains and the toxins are killed together, and the aim of eliminating is fulfilled.
Through research, the main component of most of the uvioresistant functional additives used at the present stage is nano TiO2Nanometer ZnO and other chemical assistants, and the fineness of the nanometer ZnO and other chemical assistants is controlled between 30 nm and 500 nm. The anti-infrared functional auxiliary agent is developed on the basis of ceramic powder used for far-infrared heating, so the anti-infrared functional auxiliary agent is called as far-infrared ceramic powder. The nano-composite material generally comprises nano-aluminum oxide, nano-chromium oxide, nano-magnesium oxide, nano-silicon dioxide, nano-zinc oxide, nano-antimony trioxide and the like, and the particle size of the nano-aluminum oxide, the nano-chromium oxide, the nano-magnesium oxide, the nano-silicon dioxide, the nano-zinc oxide, the nano-antimony trioxide and the like is required to be controlled below 100nm, and the nano-aluminum oxide, the nano-zinc oxide, the nano-antimony trioxide and the like are also modified.
Experiments show that when the conductivity of the conductive nano additive is 10-100 omega-cm, the garment made of the fiber has a certain electromagnetic shielding effect and can shield general electromagnetic waves; if the conductivity of the fiber is 104～105And when the fiber is omega cm, the fiber has a certain antistatic function. The conductive fiber has better performance: black conductive fiber using carbon black as conductive substance, white conductive fiber using white powder material such as nano tin dioxide, nano zinc oxide and nano titanium dioxide as conductive substanceAnd (5) chemical fiber. Mixing nanometer metal particles, nanometer oxide (such as nanometer ferric oxide and nanometer nickel oxide), and nanometer composite material (SiO)2/C/M, etc.) by blending into a melt or dope of a fiber-forming polymerIn the liquid, the material is melt spun or wet spun, or the nano stealth material is coated on the surface of the fabric by a post-finishing method to prepare the high-performance millimeter-wave stealth material which can avoid the detection of radar and infrared detectors.
The invention has the beneficial effects that by utilizing the nanotechnology, the fabric has the functions of preventing viruses and bacteria, shielding electromagnetic waves and ultraviolet rays and killing hepatitis viruses after padding and heat treatment. For example, the fabric can be treated with citric acid, malic acid, lauric acid, ester sulfate, etc. to achieve the function of preventing cold. Such as mixing nano SiO2Or TiO2The modified fabric has amphiphobic property (namely, water and oil repellency), and can achieve the water and oil repellent effect of the fabric for a long time. The fabric can be subjected to flame retardant treatment by using nano antimony trioxide. If the coated mosquito and fly repellent, the permethrin and the synergist are added, the fabric can achieve the long-term mosquito and fly repellent effect. If polyethylene glycol with different molecular weights is padded and heat treated, a layer of phase change film can be formed on the surface of the fabric, so that the temperature control effect is achieved.
