Embodiment 1

[0032] First prepare Ag / TiO 2 Composite sol antibacterial agent, its steps are:

[0033] Dissolve 10 g of metatitanic acid in 100 ml of water, then adjust the solution with 1.0 mol / L sodium hydroxide solution until the pH value is >9.0, and then stir.

[0034] After precipitation and stratification, the supernatant was sucked away, and then 0.1 mol / L hydrochloric acid solution was added to the precipitate, the pH was about 1.0, and then the supernatant was sucked away.

[0035] The above precipitate was added to 100 ml of hydrochloric acid (0.1 mol / L) solution, and then treated with stirring at 80° C. for 24 hours. Final pH to 0.5-0.8. Note that this temperature is the solution temperature and not the temperature indicated by the heater. Regulated TiO 2 The solid content of the hydrosol is up to 8%.

[0036] Add 8% TiO in 1000g deionized water 2 Hydrosol 15g, AgNO 3 15g, cationic water-based resin 13g, the resulting treatment solution was vigorously stirred for 3min to ...

Abstract

The invention discloses an antibacterial fabric which comprises 0.005 to 0.1 weight percent of Ag+, 0.01 to 0.2 weight percent of titanium dioxide and the balance fabric. 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 [0001] The present invention relates to a kind of fabric, particularly a kind of through Ag / TiO 2 Antibacterial functional fabric after composite sol finishing. Background technique [0002] In order to make the fabric more hygienic, prevent infectious diseases, ensure the safety and health of the human body, enhance its comfort, and reduce the cross-infection rate in the public environment, the antibacterial and hygienic finishing of textiles has become more important. Studies and applications have shown that silver-containing antibacterial agents are highly safe, non-volatile, difficult to decompose, good heat resistance, harmless to the human body, long-acting antibacterial, and anti-mildew. The antibacterial effect of metals and their ions belongs to contact antibacterial, because silver and its compounds have strong antibacterial ability. Titanium dioxide is stable and non-toxic, and it needs to be irradiated by ultraviolet rays to exert its photocatal...
