Problems solved by technology

The production efficiency is low, the cost is high, and the pollution is serious. The production process is always strictly restricted by the environmental protection department.
However, the production technology of silver-plated fiber is relatively kept secret in foreign countries, and the production cost is high. Therefore, although silver-plated fiber appears on the market, its quality level and large-scale production cannot meet social needs.

Abstract

The invention discloses a method for preparing nano-metal antibacterial fibers by adopting a physical deposition process. High-pressure superfine water flow is injected to a multilayer fiber mesh, so that fibers are intertwisted into a coil, and coiled fibers are obtained; the coiled fibers are put in a vacuum chamber, argon is introduced to the vacuum chamber, and a metal target material is sputtered under negative pressure by adopting magnetron sputtering coating equipment. The method has the advantages of no wastewater discharge during preparation, long service life, no volatility, no environmental pollution, wide-spectrum and high-efficiency antibiosis, difficulty in drug resistance generation and the like.

Description

technical field [0001] The invention belongs to the technical field of preparation of antibacterial materials, and in particular relates to a method for preparing nanometer metal antibacterial fibers by using a physical deposition process. Background technique [0002] Antibacterial materials can generally be divided into two categories: organic antibacterial materials and inorganic antibacterial materials. Generally, organic antibacterial materials are divided into more than 20 categories according to their chemical molecular structures, such as aldehyde-based aqueous solutions with relatively simple structures and isothiazoles and imidazoles with complex structures, etc., which are characterized by certain volatility. And toxicity, poor temperature resistance, generally within 200 °C, long-term use will cause dissolution, precipitation, etc., easy to cause irritation and corrosion to the skin and eyes, and some even have potential risks of carcinogenicity and scurvy, so us...
