Problems solved by technology

At present, the research on the preparation and application of antibacterial materials using nano-silver has become a focus, but there are problems in the dispersion of nanoparticles and the influence of nanoparticles on the performance of the main fiber in the process of using nano-metal particles as fillers to prepare antibacterial fibers; Fabric finishing methods will inevitably produce processing pollution
The problem of the combination of the above-mentioned metal ion-type inorganic antibacterial agents with fabrics has not been effectively used, so it is necessary to develop research on its processing and preparation methods

Embodiment 1

[0025] (1) Choose polyester (PET) hot-rolled spunbonded nonwovens (100g / m 2 ); high-purity silver target (purity 99.99%).

[0026] (2) Cleaning: put it in acetone solution and wash it with an ultrasonic cleaner for 25 minutes to remove organic solvents, dust and other impurities on the surface of the fabric, improve the adhesion between the film and the substrate, and then rinse it repeatedly with deionized water , put it into a 45°C oven and dry it for later use.

[0027] (3) Pretreatment: Argon (Ar) is selected as the working gas for plasma pretreatment. The pretreatment process is as follows: hang the cleaned and dried fabric in the plasma treatment chamber, open the vacuum pumping valve, and wait until the vacuum degree reaches below 10Pa After that, 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.

Abstract

The invention discloses a method for preparing an antibacterial filter screen, belonging to a new spinning material with filter function. The new material consists of base material and films, whereinthe base material is latticed textile formed from chemical fibre by weaving, knitting or non-weaving manners, and the films with nanometer structure has an antibacterial function. The films are formedby metal or rare-earth metal antibacterial material by a low-temperature magnetron sputtering method. In order to improve the adhesion property of the films and the base material, the base material is preprocessed before sputtering, and the antibacterial target is directly sputtered on the surface of the latticed textile in preparation. The material is applicable to air filter screens and other filter fields, thereby improving the air or liquid quality and being beneficial to the health of human bodies.

Description

technical field [0001] The invention relates to the field of new filtering materials, in particular to a preparation method of an antibacterial filter net. Background technique [0002] Traditional organic antibacterial agents have inherent limitations in antibacterial spectrum, heat and weather resistance, persistence, safety in use, and acquisition of bacterial drug resistance, so their application is limited in some occasions. Inorganic antibacterial agents have the advantages of broad spectrum, durability, safety, etc., and have broad market application prospects. At present, the widely used inorganic antibacterial agents mainly include metal ion-type inorganic antibacterial agents with silver and other metal ions as active components, and nano-titanium dioxide (TiO 2 ) as the representative photocatalytic inorganic antibacterial agent. As a new type of antibacterial measure, inorganic antibacterial agents have successfully overcome the inherent limitations of organic a...
