Description
Technical field
The present invention relates to a kind of fabric, particularly one is through Ag/Ti0
2antibacterial functions fabric after complex sol arranges.
Background technology
For making fabric health care more, prevent communicate illness, ensure human body safety and Health, strengthen its comfort simultaneously, and reduce the cross-infection rate of PE, the anti-bacteria health finishing of textiles becomes more important.Study and appliance shows, silver-containing antibacterial agent security is high, not volatile, not easily decomposes, good heat resistance, harmless, energy long acting antibiotic, mildew-resistant.It is antibacterial that the antibacterial action of metal and ion thereof belongs to contact, due to silver and antifungal ability stronger.Titanium dioxide is stablized nontoxic, need through the effect of Ultraviolet radiation competence exertion photo-catalyst, so the participation of silver can improve the photocatalysis performance of titanium dioxide.
Silver ion antimicrobial agent is not widely used in daily use chemicals industry at present, and one is because its high cost, and two is because its chemical property is enlivened, easily aging and variable color.In order to address these problems, researcher mainly adopt silver and zinc, copper composite, or with inorganicly and organically composite reducing costs, suppressing variable color, also have directly interpolation discoloration inhibitor or ultra-violet absorber, antioxidant etc. to ensure that it is stable.
TiO
2excellent with its catalytic performance, chemical stability good, nontoxic corrosion-free, cost is low, long service life etc. gains great popularity a little, be to generally acknowledge the most at present, use one of the widest photochemical catalyst.Compared with organic antibacterial agent, inorganic antiseptic is high with its good heat resistance, security, long service life, the advantage such as non-volatile become one of focus of current antiseptic exploitation.The antibacterial wide spectrum of silver-containing inorganic antibacterial, bactericidal properties be high, not easily develop immunity to drugs, harmless, and can long acting antibiotic, mildew-resistant.According to different sterilization mechanisms, be antibacterially divided into the antibacterial and photocatalysis antibacterial of contact.The antibacterial action of metal and ion thereof belongs to the former.Silver and a kind of broad-spectrum sterilization material of compound foot thereof, sterilizing ability is stronger.Therefore, with nano-TiO
2appearance for the Ag-type Inorganic Composite Antibacterial of carrier shows huge superiority.Pass through Ag
+mix, both effectively can prevent TiO
2the compound of electron-hole pair during photocatalysis, can realize nano-TiO again
2and Ag
+synergetic antibacterial effect.
