Embodiment 1

[0018] The silver metallization preparation process of polyester filaments comprises the following steps: (1), substrate: polyester filament tow, specification 75dtex / 48f, monofilament cross-section geometry pattern is triangular special-shaped cross-section, (2), above-mentioned base material 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 material is 50mm, adopt the method of vacuum magnetron sputtering coating to sputter and silver-plate, and the pressure in the vacuum chamber is pumped to 1.2×10 -2 Pa, and then pass in argon gas with a flow rate of 240ml / min. At this time, the vacuum degree reaches 2.2×10-1...

Embodiment 2

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

This is a argent metallization producing method of organic fibre and fabric, which belongs to vacuum membrane plating and electroplating technologic field and mainly solves the problems of quality and producing batches of silver-gilt organic and fabric. Through physical vapour phase deposition technology, it firstly arranges smoothly and rolls up tidily the organic fibre bundle and fabric; lay them in the vacuum room, plate silver by magnetic controlling and sputtering, and monolayer or multilayer continuously plate membrane; then plate mulriple argent membrane according to different using demands. The binding force of the metallic argentic ion and organ fibre of the present invention is strong, it has no pollution, low costs and can be continuously produced. The products are applied in such industry as electronics, war industry communication, medical treatment, special type of spinning and so on. For instance, electric shielded products, military used shielded tent, special type of spinning antibacterial materials and civil health care spinning products.

Description

[0001] Field [0002] The invention relates to a preparation method for silver metallization of organic fibers and fabrics, belonging to the technical field of vacuum coating and electroplating. Background technique [0003] 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. Silver-plated organic fibers and fabrics are new materials for electromagnetic shielding and special textiles. They are mainly used in electronics, communications, medical equipment, military and functional textiles. Silver-plated organic fibers and fabrics have a tendency to replace nickel-plated fibers and fabrics. Because most of the current domestic existing technologies do not have the conditions for mass production of silver-plated fibers in the experimental stage, the urgently needed silver-plated fibers and fabrics have to be imported in batches. At p...
