Problems solved by technology

But TiO 2 Photocatalytic materials mainly use ultraviolet light below 387.5nm. This part of light radiates to the ground only accounts for about 4% of the total light radiation, and even less can enter the room. TiO alone 2 Thin film antibacterial effect is rather limited

Embodiment 1

[0025] (1) Choose polyester (PET) hot-rolled spunbonded nonwovens (100g / m 2 ); high-purity TiO 2 Target (purity: 91.8%) and rare earth Nd target (purity: 99.99%) were used to prepare composite films on the surface of the fabric by spaced sputtering.

[0026] (2) Cleaning: put the above-mentioned nonwoven fabric in an acetone solution and wash it with an ultrasonic cleaner for 25 minutes, then rinse it repeatedly with deionized water, and put it in an oven at 45°C to dry it for use.

[0027] (3) Plasma pretreatment: select Ar as the working gas for plasma pretreatment. The pretreatment process is as follows: hang the nonwoven fabric after cleaning and drying on the sample rack in the plasma treatment chamber, open the vacuum pumping valve, and wait for the vacuum After the temperature reaches below 10Pa, the working gas is introduced. Adjust the vacuum to 20Pa, turn on the RF power supply, adjust the power to 40W, and take it out after 2 minutes of treatment.

[0028] (4) Sp...

Embodiment 2

[0031] (1) Select polyester / cotton (65% / 35%) blended woven fabric, specification: 13 / 13 (tex), 531.5 / 392 (root / 10 cm); high-purity TiO 2 target (purity: 91.8%) and rare earth La target (purity: 99.99%), the composite thin film was prepared on the surface of the fabric by spaced sputtering.

[0032] (2) Cleaning: the above-mentioned fabric was washed in an acetone solution for 30 minutes with an ultrasonic washer, then repeatedly rinsed with deionized water, and then dried in an oven at 45° C. for use.

[0033](3) Plasma pretreatment: He is selected as the working gas for plasma pretreatment. The pretreatment process is as follows: hang the cleaned and dried fabric on the sample rack in the plasma treatment chamber, open the vacuum pumping valve, and wait until the vacuum degree reaches After the pressure is below 10Pa, the working gas is introduced. Adjust the vacuum to 20Pa, turn on the RF power supply, adjust the power to 40W, and take it out after 2 minutes of treatment. ...

Embodiment 3

[0037] (1) Select the yarn count of 40S / 2 from 40% wool, 40% modal fiber and 20% pearl fiber as a raw material for knitting fabric; high-purity TiO 2 target (91.8% purity) and rare earth Ce target (99.99% purity).

[0038] (2) Cleaning: Put the above-mentioned knitted fabric in an acetone solution and wash it with an ultrasonic cleaner for 20 minutes, then rinse it repeatedly with deionized water, and dry it in an oven at 45°C for use.

[0039] (3) Plasma pretreatment: choose O 2 Or air is the working gas for plasma pretreatment. The pretreatment process is as follows: Hang the knitted fabric after cleaning and drying on the sample rack in the plasma treatment room, open the vacuum valve, and after the vacuum degree reaches below 10Pa, enter the working gas. Adjust the vacuum to 20Pa, turn on the RF power supply, adjust the power to 40W, and take it out after 2 minutes of treatment.

[0040] (4) Sputtering: Put the pretreated knitted fabric into the sputtering chamber, the ...

Abstract

The invention relates to an anti-bacterial fabric and a prepration method thereof, the anti-bacterial fabric consists of a fabric substrate and a composite thin film composed on the surface of the fabric substrate, and the structure of the composite thin film is TiO2 / rare earth, rare earth / TiO2, TiO2 / rare earth / TiO2 or rare earth / TiO2 / rare earth, wherein, the rare earth is Nd, La or Ce. The composite thin film is formed by directly sputtering an anti-bacterial target to the surface of the fabric substrate by adopting the magnetron sputtering method, thereby forming the anti-bacterial fabric; and the preparation process comprises the following steps: step 1, cleaning and drying; 2, plasma pretreatment; 3, sputtering: arranging the fabric substrate after the pretreatment on a sample holder in a sputtering cavity, keeping the spacing interval between the target and the fabric substrate to be 10-200mm, adopting a water cooling device for cooling the fabric substrate, firstly pumping a reaction chamber till base vacuum, and then introducing Ar gas for being taken as sputtering gas for sputtering and forming the film. The method can broaden the absorption spectrum of nano-TiO2, thereby having better anti-bacterial effect under the visible light radiation situation.
