Problems solved by technology

[0003] In the prior art, silver phosphate is loaded on the surface of fabric cloth by first preparing silver phosphate powder, then making it into an aqueous dispersion and then loading it on the surface of cotton fabric [Preparation of Ag3PO4 / TiO2 Loaded Functional Fabric and Its Response to Organic Pollutants] Explain [D]. Zhejiang Sci-tech University, 2018]. This method has at least the following disadvantages: (1) It does not avoid silver phosphate dust pollution; (2) The prepared silver phosphate aqueous dispersion is unstable and difficult to adapt to industrial production; ( 3) The process route is too long and the preparation process is complicated; (4) The silver phosphate particles loaded on the fiber surface are unstable and easy to fall off from the fiber surface
However, when silver phosphate is used as a target alone, the silver phosphate coating loaded on the surface of the fabric is easy to fall off.

Embodiment 1

[0043] The silver target and the silver phosphate target are placed on the magnetron sputtering equipment according to the quantity ratio of 1:1 as multiple groups,

[0044] Set the sputtering voltage to 1kV, choose the cleaned nylon cloth as the base cloth, and control the continuous sputtering time for 10 minutes by the winding and unwinding equipment, and the prepared silver-based fabric cloth is labeled as YZW-1. Use scanning electron microscope (SEM) to observe the coating morphology before and after washing 50 times. After washing, the silver / silver phosphate composite coating has almost no change. According to the national standard GB / T20944.3-2008 oscillation method, the antibacterial rate before washing is >99% , The antibacterial rate is 98% after 50 times of washing.

Embodiment 2

[0046] The silver target and the silver phosphate target are placed on the magnetron sputtering equipment at multiple intervals according to the quantity ratio of 3:1, the sputtering voltage is 3kV, and the polyester cloth after cleaning is selected as the base cloth, which is controlled continuously by the unwinding and unwinding equipment. The sputtering time was 5 minutes, and the silver-based fabric cloth was prepared as YZW-2. The morphology of the coating before and after washing 50 times was observed with a scanning electron microscope (SEM), and the silver / silver phosphate composite coating was almost unchanged after washing. According to the national standard GB / T20944 .3-2008 Oscillating test results showed that the antibacterial rate was >99% before washing, and the antibacterial rate was 99% after 50 times of washing.

Embodiment 3

Abstract

The invention belongs to the technical field of surface treatment of antibacterial fabric cloth, and particularly relates to a treatment method for silver / silver phosphate loaded on the fabric cloth surface by utilizing a sputter coating technology. The treatment method for silver / silver phosphate loaded on the surface of fabric cloth comprises the steps that silver targets with the purity larger than 99.99% and silver phosphate targets with the purity larger than 99% are selected and arranged into multiple groups according to a certain quantitative proportion, the silver targets and the silver phosphate targets are sequentially installed in the groups, and the groups are sequentially installed in a vacuum sputtering cavity of magnetron sputtering equipment at intervals; base fabric cloth is selected and treated; and the sputtering voltage is adjusted to be 1-5 kV, and the continuous sputtering time is adjusted to be 1-10 min. According to the method, the agglomeration resistance of the silver phosphate and the combination firmness of the fabric are remarkably improved, the whole process is free of pollution, continuous and automatic film coating is achieved, and large-scale and industrial production can be carried out.

Description

technical field [0001] The invention belongs to the technical field of surface treatment of antibacterial fabric cloth, and in particular relates to a treatment method for carrying silver / silver phosphate on the surface of fabric cloth by sputtering coating technology. Background technique [0002] Silver phosphate chemical formula: Ag 3 PO 4 , melting point: 849 ° C, with physical and chemical properties such as slightly soluble in water. Silver phosphate has good photocatalytic properties. In the visible light wavelength range, it catalyzes the production of active oxygen, which can quickly kill bacteria. Combined with its high melting point, slightly soluble in water, and photocatalytic sterilization, the surface of the fabric is loaded with silver phosphate, so that the fabric has antibacterial properties. [0003] In the prior art, silver phosphate is loaded on the surface of fabric cloth by first preparing silver phosphate powder, then making it into an aqueous disp...
