Technology for plating nano-metal on fiber

Abstract

The invention relates to a technology for plating nano-metal on fiber, which is characterized in that natural fiber or chemical fiber is selected for producing a substrate, and cleaning, washing by water and drying pretreatment are carried out on the substrate; sputtering film coating is implemented on the surface of the substrate after the pretreatment; and a water-based polyurethane protective layer is coated on the surface of the substrate after plating a metal film, and the substrate after the treatment of coating with a protective layer is washed by water and dried, thereby obtaining a finished product. Silver-plated fabric has very high conductive performance and flexible performance, and the shielding effect can be more than 40DB which is much higher than copper and nickel-plated conductive fabric in the current market; and zinc-plated fiber simultaneously has good anti-bacterial and anti-ultraviolet functions.

Description

technical field

[0001] The invention belongs to the field of functional textile materials, and in particular relates to a process for plating nano metal on fibers. Background technique

[0002] With the development of electronic technology, electronics, electrical equipment, PDP-TV, LCD-TV and office automation systems have been widely used. Due to the increase of these devices, electromagnetic interference is also increasing, and the electromagnetic environment is getting worse and worse. Signal distortion and errors caused by electronic instruments are common, and the losses are incalculable. At the same time, electromagnetic radiation has an increasingly serious impact on human health. The copper-nickel-plated conductive cloth currently popular in the market can no longer meet the needs of the rapid development of electronic equipment and precision instruments and the needs of people's healthy life. Copper-plated silver conductive cloth, pure silver-plated conductive clo...
