The invention also discloses a production method of the antibacterial fabric. The production method comprises the following steps of 1. preparing Ag/TiO2 composite sol; and 2. performing antibacterial finishing on the fabric by utilizing the Ag/TiO2 composite sol. According to the antibacterial fabric and the production method of the antibacterial fabric, the growth and the reproduction of harmful bacteria on a fleece fabric subjected to the treatment of the Ag/TiO2 composite sol serving as an antibacterial agent can be effectively suppressed and eliminated; the antibacterial fabric has an antibacterial function, a mildew-proof function, a deodorization function and the like, has good effects, and is high in safety and washable.
Description
Technical field
The present invention relates to a kind of fabric, particularly a kind of through Ag/TiO
2antibacterial functions fabric after complex sol arranges.
Background technology
For making fabric health care more, prevent communicate illness, guarantee 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.Research and application show, silver-containing antibacterial agent is safe, not volatile, be difficult for to decompose, and good heat resistance, harmless, can long acting antibiotic, mildew-resistant.It is antibiotic that the antibacterial action of metal and ion thereof belongs to contact, due to silver and compound antibacterial ability stronger.Titanium dioxide is stablized nontoxic, needs to irradiate the effect of competence exertion photo-catalyst through ultraviolet ray, 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 the one, because its high cost, the 2nd, because its chemical property is active, easily aging and variable color.In order to address these problems, researcher mainly adopts the composite of silver and zinc, copper, or with the inorganic and organic composite variable color that reduces costs, suppresses, and also has direct interpolation discoloration inhibitor or ultra-violet absorber, antioxidant etc. to guarantee that it stablizes.
TiO
2good 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.Compare with organic antibacterial agent, inorganic antiseptic becomes one of focus of current antiseptic exploitation with its good heat resistance, safe, long service life, the advantage such as non-volatile.The antibiotic wide spectrum of silver-containing inorganic antibacterial, bactericidal properties be high, be difficult for developing immunity to drugs, harmless, and can long acting antibiotic, mildew-resistant.According to different sterilization mechanisms, the antibiotic antibiotic and photocatalysis antibacterial of contact that is divided into.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
2for the appearance of the Ag-type Inorganic Composite Antibacterial of carrier shows huge superiority.Pass through Ag
+mix, both can effectively prevent TiO
2during photocatalysis, electron-hole pair is compound, can realize nano-TiO again
2and Ag
+synergetic antibacterial effect.
