Problems solved by technology

This can play a certain antibacterial effect in a short period of time, but with the passage of time, the antibacterial effect will drop significantly
Simultaneously, because the type of antibacterial agent used is relatively single, the antibacterial effect is also not ideal enough.

Embodiment 1

[0035] 1) Pre-treat the surface of the fabric, wash it with an organic solvent and deionized water in sequence under ultrasonic conditions, the cleaning time is 10 minutes, and finally dry it at 25°C for 1 hour under vacuum conditions. The organic solvent is acetone and ethanol mixture;

[0036] 2) Fill the container with titanium target, silver target and germanium target with argon, and use vacuum equipment to reduce the pressure in the container to a vacuum degree of 10 -2 torr, oxygen is introduced, the pressure in the container is controlled to 2 mtorr, and the temperature is 50°C. Direct current is passed through the titanium target, silver target and germanium target to generate plasma discharge. The voltage of the direct current: 300V, the current density: 6mA / cm 2 , power density: 5W / cm 2 ;

[0037] 3) Pass the cloth through the titanium target, silver target and germanium target at a uniform speed in a retracted manner, so that the three metal ions are anchored in...

Embodiment 2

[0041] Repeating Example 1 is just that the pretreatment of the cloth uses electrophoresis to remove the cloth surface pollutants; the pressure in the container drops to a vacuum degree of 10 -3 torr, oxygen is introduced, the pressure in the container is controlled to 4 mtorr, the temperature is 80°C, the voltage of the direct current: 500V, the current density: 10mA / cm 2 , power density: 10W / cm 2 In addition, a magnetic field parallel to the surface of the titanium target, silver target and germanium target source is set in the container, and the magnetic field strength is 50Gs; the maximum deposition rate of the titanium target, silver target and germanium target is 200nm / min.

Embodiment 3

[0043] Repeat Example 1 only to set a magnetic field parallel to the surface of the titanium target, silver target and germanium target source in the container, and the pressure in the container drops to a vacuum degree of 10 -5 torr, feed oxygen, control the pressure in the container to 10 mtorr, the temperature to 250°C, the voltage of the direct current: 800V, the current density: 60mA / cm 2 , power density: 40W / cm 2 , the magnetic field strength is 280Gs; the maximum deposition rate of titanium target, silver target and germanium target is 1000nm / min.

Abstract

The invention provides a method for manufacturing anti-bacterial cloth through the vacuum ion anchoring technology. The method comprises the following steps: the surface of cloth material is pre-treated; a container where a titanium target, a silver target and a germanium target are mounted is filled with inert gas; the pressure in the container is reduced to a vacuum degree of 10-1torr to 10-5torr through vacuum equipment; oxygen gas is led into the container; the pressure in the container is controlled to be 1mtorr to 10mtorr, and the temperature is controlled to be 20 DEG C to 250 DEG C; direct current is led into the titanium target, the silver target and the germanium target at a preset power, so as to produce plasma discharge; the cloth material passes through the titanium target, the silver target and the germanium target at a constant speed in a furled manner, and three metal ions are anchored inside and on the edge of fiber; the maximum deposition rates of the titanium target, the silver target and the germanium target range from 100nm / min to 1,000nm / min; and the cloth material is trimmed, edged, packaged in a vacuum manner, and sent to a radiation exposure center, so as to remove bacteria and bacterial colonies again.

Description

technical field [0001] The invention relates to a method for manufacturing antibacterial cloth by vacuum ion anchoring technology. Background technique [0002] Microorganisms are ubiquitous in nature and are inseparable from human life. In daily life, textiles are good parasites for these microorganisms. Common microorganisms on textiles mainly include Escherichia coli and Staphylococcus aureus. Escherichia coli can easily cause acute diarrhea; Staphylococcus aureus is the most common pathogenic bacteria in human purulent infection. For the sake of human health, people use various means to inhibit the growth and reproduction of pathogenic bacteria to achieve the purpose of antibacterial and antibacterial. The human body carries a large number of microorganisms under normal conditions, and these bacteria cannot be eliminated even after repeated washing. The situation is even more serious in a special environment. Bacteria, especially the SARS virus spread and harmed rapid...
