Embodiment 1

[0009] Production equipment: roll-to-roll magnetron sputtering coating machine.

[0010] Substrate: polyester film with a thickness of 6 μm.

[0011] Target material: an indium tin oxide target with a purity of 99.99% (sintered from 97wt% In2O3 and 3wt% SnO2).

[0012] Production conditions: the purity of the working air for sputtering is 99.99% argon (AR), the background vacuum degree of the vacuum chamber is 10-3Pa, the distance between the substrate and the target is fixed at 0.12m, the working pressure is 0.3Pa, and the winding speed is 10m / min, the sputtering power is 1500W.

[0013] After coating the polyester film on both sides, it is finely cut, and the cutting width is 0.1mm. Then roll forming is carried out. Since the thickness of the film is only 6μm, the cutting width is only 0.1mm, so the flexibility is good, and the wound fiber filaments can be cut again, and the cutting distance is 25mm. That is, polyester staple fibers coated with an indium tin oxide film l...

Embodiment 2

[0015] Production equipment: roll-to-roll magnetron sputtering coating machine.

[0016] Substrate: polyester film with a thickness of 35 μm.

[0017] Target material: an indium tin oxide target with a purity of 99.99% (sintered from 97wt% In2O3 and 3wt% SnO2).

[0018] Production conditions: the purity of the working air for sputtering is 99.99% argon (Ar), the background vacuum degree of the vacuum chamber is 10-3Pa, the distance between the substrate and the target is fixed at 0.12m, the working air pressure is 0.3Pa, and the winding speed is 2m / min, the sputtering power is 2000W.

[0019] After coating the polyester film on both sides, it is finely cut, and the cutting width is 0.65mm. Then roll forming is carried out. That is, a polyester filament coated with an indium tin oxide film layer and having a rectangular cross section is obtained. The specific specifications are: the width of the polyester filament cross-section is 0.65mm, the thickness is 35μm, and the thic...

Abstract

The invention discloses a production method of polyester profiled fiber plated with indium tin oxide, comprising the following steps of: carrying out magnetron sputtering coating on a polyester film, plating indium tin oxide on two faces of the film, carrying out micro-cutting on the plated film, and carrying out winding shaping so as to prepare the polyester fiber plated with indium tin oxide. The thickness of the indium tin oxide thin layer is 10-500 nm. The micro-cutting width of the film is 0.1-1.0 mm. The thickness of the used film is 5-50 microns.

Description

technical field [0001] The present invention relates to a kind of production method of polyester fiber, more specifically, it relates to a kind of production method of polyester shaped fiber coated with indium tin oxide. technical background [0002] Indium tin oxide thin film, referred to as ITO thin film, has high transmittance in the visible light range, high infrared reflectance, good electrical conductivity and other properties. These properties make ITO films widely used in the manufacture of various devices, such as organic light-emitting devices for color displays, liquid crystal screens, automotive films, solar cells, and automotive anti-fog glass. In addition, the ITO film also has a strong attenuation effect on microwaves. Therefore, the effective combination of the excellent photoelectric properties of indium tin oxide film and textile fibers can make the fibers obtain a series of special functions, such as antistatic, infrared stealth, microwave shielding and a...
