Problems solved by technology

This process has the disadvantages of high pollution, high cost, poor adhesion, etc.
[0004] In the prior art, there is a silver fiber with nanoscale technology, which is to make silver evenly distributed in various parts of the cross section of the fiber through nanoscale technology, so that to a certain extent the antibacterial effect can be achieved, but it is not suitable for antibacterial applications. In terms of the field, the silver that can play an antibacterial role should be the silver that is distributed on the surface of the material and has the opportunity to contact the outside world, while the silver inside the fiber has little effect on antibacterial

preparation example Construction

[0018] Such as figure 1 as shown, figure 1 It is a flowchart of the production and preparation method of the silver-plated fiber of the present invention. In step 101, a certain pressure of argon gas is introduced into the vacuum chamber, and the substrate is bombarded on both sides by using plasma or ion source equipment in the front chamber of the vacuum machine. Among them, the base material is chemical fiber fabric or non-woven fabric, chemical fiber fabric includes: polyester cloth, nylon cloth, cloth base specification is 180T-360T, fiber filament diameter is 10-80um, specification is 20dtex / 1f-24f to 75dtex / 1f-24f; the non-woven fabric is polyester spunlace non-woven fabric, nylon non-woven fabric, viscose non-woven fabric, cellulose non-woven fabric, etc., with a thickness of 0.05-0.4mm and a weight of 30-120g / m2 . During double-sided bombardment treatment, impurities such as oil stains and particles attached to the surface of the substrate can be removed. The pro...

Abstract

The invention provides a method for productive preparation of silver-plated fibers. The method for the productive preparation of the silver-plated fibers comprises the following steps of: introducing argon with a certain pressure into a vacuum chamber, and performing double-sided bombardment on a base material in the vacuum chamber by using plasma or ion source equipment; vacuum-sputtering metallic silver on the base material subjected to the double-sided bombardment in the vacuum chamber; and loosening and cutting the base material subjected to the double-sided bombardment and the metallic silver vacuum sputtering so as to prepare the silver-plated fibers. By the method for the productive preparation of the silver-plated fibers, the problems of high pollution, high cost, poor adhesive force, limited antibacterial action and the like in the prior art are solved, and the advantages of uniform plating without impurities, good adhesive force, low cost and good antibacterial action are achieved.

Description

technical field [0001] The invention relates to the field of vacuum coating, in particular to a production and preparation method of silver-plated fibers. Background technique [0002] Metal silver has its own unique natural advantages. It is a soft metal substance in nature. It has a broad-spectrum antibacterial effect and has no toxic or side effects on the human body. The invented antibacterial silver fiber, after being mixed with other fibers, the fabric produced after direct contact with human skin can help the skin to avoid the erosion of bacteria, inhibit the growth of bacteria, and also play a certain antistatic effect, and is more and more popular in the society. widely used. [0003] At present, the process production method of silver fiber generally adopts the chemical silver plating process. This process has the disadvantages of high pollution, high cost, and poor adhesion. [0004] In the prior art, there is a silver fiber with nanoscale technology, which is ...
