Problems solved by technology

When the weather is cold in winter, the way to keep clothes warm is to insulate the skin from the air to reduce convective heat loss; and store air by filling cotton or down, and use the heat insulation performance of the air to reduce the loss of heat transfer. , the infrared heat radiation of the human body, the existing fabrics do not have a good protective effect; and when the weather is hot in summer, people can only reduce the body heat by reducing the clothing and increasing the contact between the skin and the air, but for the sunlight The infrared radiation of 46% of the solar energy, and the infrared radiation of the surrounding high temperature environment, the existing fabrics do not have a good shielding effect

Abstract

The invention discloses a golden yellow fabric for shielding infrared thermal radiation. By using a magnetron sputtering vacuum deposition method, a composite membrane layer is deposited on the surface of a fabric; the composite membrane consists of a medium layer, a metal silver membrane layer, a metal copper membrane layer, a nickel-chromium membrane layer and a protection layer; the metal copper membrane layer has the main contribution of a golden yellow color; a low-radiation effect for shielding infrared thermal radiation is mainly achieved by the metal silver membrane layer and the metalcopper membrane layer. By adopting the fabric, a large scale of fabrics have infrared thermal radiation shielding functions rapidly, and a relatively good thermal-insulating and heat-preservation effect can be achieved; in addition, magnetron sputtering vacuum membrane plating has no problem of chemical use, water pollution or air pollution, and is an environmental-friendly production mode.

Description

technical field [0001] The invention belongs to the field of innovative textiles, and is a golden yellow fabric shielding infrared heat radiation. Background technique [0002] Heat spreads outward through three main routes: heat transfer, convection, and infrared heat radiation. When the weather is cold in winter, the way to keep clothes warm is to insulate the skin from the air to reduce convective heat loss; and store air by filling cotton or down, and use the heat insulation performance of the air to reduce the loss of heat transfer. , the infrared heat radiation of the human body, the existing fabrics do not have a good protective effect; and when the weather is hot in summer, people can only reduce the body heat by reducing the clothing and increasing the contact between the skin and the air, but for the sunlight The infrared radiation of 46% of solar energy and the infrared radiation of the surrounding high temperature environment, the existing fabrics do not have a ...
