Embodiment 1

[0018] The chromium metallization preparation process of polyester filaments includes the following steps: (1), substrate: polyester filament tow, specification 75dtex / 48f, monofilament cross-section geometric pattern is a triangular shaped cross-section, (2), the above-mentioned substrate Routine cleaning, roughening, drying. (3), the polyester tow is warped according to the weaving warping process, the tow width is 1100mm, the tow density is 4800 / m, and the tow weight per square meter is 36.3 grams. After warping, the tow on the warp beam is Coils are loaded onto vacuum coating mandrels. (4), put the above-mentioned substrate into the vacuum chamber, the distance between the substrate and the target is 50mm, adopt the method of vacuum magnetron sputtering coating to sputter chrome plating, and pump the pressure in the vacuum chamber to 1.2×10 -2 Pa, then argon gas is introduced, the flow rate is 240ml / min, and the vacuum degree reaches 2.2×10 -2 Pa, adjust the current and ...

Embodiment 2

[0019] The difference between embodiment 2 and embodiment 1 is that after the vacuum magnetron sputtering chromium film, the method of electroplating plastic is used to electroplate chrome on the vacuum chrome-plated polyester filament.

Embodiment 3

[0020] The difference between embodiment 3 and embodiment 1 is that the substrate is nylon filament (77dtex / 24f), and the arrangement density on the warp beam is 3200 filaments / m, 24.64 grams per square meter. The monofilament section geometry is triangular shaped.

Abstract

An organic fiber surface chromium-plating method belongs to the field of a vacuum coating and electroplating technology. According to the invention, quality and production lot-sizing problems of chromium-plated organic fiber are mainly solved. By a physical vapor deposition technology and a composite coating technology, organic fiber tow and organic fiber fabric are firstly arranged to be smooth and packaged to be tidy; the materials are put into a vacuum chamber to undergo magnetron sputtering chromium-plating and single-layer or multi-layer continuous coating; and according to different usage requirements, composite chromium film electroplating is carried out. The method has advantages of strong binding force between metallic chromium ions and organic fiber, no pollution, low cost and continuous production. The product is used in the industries such as electron, military communication, medical treatment and special textile, etc. By the method, products such as manufacture products such as electronic screening products, military screening tents, special textile antibacterial materials and health-care textile products for civil use can be manufactured.

Description

technical field [0001] The invention relates to a preparation method for chromium metallization of organic fibers, which belongs to the technical field of vacuum coating and electroplating. Background technique [0002] The shielding materials used in China are mainly nickel-plated fiber fabrics. The disadvantages are hardening, not resistant to folding, not durable to washing, and allergic to human skin irritation. Chrome-plated organic fibers are new materials for electromagnetic shielding and special textiles. They are mainly used in electronics, communications, medical equipment, military and functional textiles. Chrome-plated organic fibers have a tendency to replace nickel-plated fibers and fabrics. Because most of the existing domestic technical processes are not ready for mass production of chrome-plated fibers in the experimental stage, the urgently needed chrome-plated fibers and fabrics have to be imported in batches. At present, only one or two small processing ...
