Abstract

The invention discloses multi-layer fabric and a preparation method thereof, and belongs to the field of high polymer materials. The multi-layer fabric sequentially comprises a first high polymer porous thin film, a carbon black coating layer, a second high polymer porous thin film, a copper coating layer and a third high polymer porous thin film from top to bottom, wherein the first high polymerporous thin film, the second high polymer porous thin film and the third high polymer porous thin film are nano-scale porous PE (Polyethylene) films, nano-scale porous TPU (Thermoplastic Polyurethane)films, nano-scale porous PTFE (Polytetrafluoroethylene) films or nano-scale porous PP (Polypropylene) films. The multi-layer fabric disclosed by the invention has the beneficial effects that high polymer porous thin films are adopted as a base material framework, the middle part is coated with a carbon black layer and a copper coating layer, and a double-layer irradiating body is formed by the carbon black layer having ultrahigh radiance and the copper layer having ultralow radiance; when a carbon layer faces outwards, heat dispersed through radiation will be greater than heat generated in abody, so that descending of body surface temperature is caused; when the copper layer faces outwards, the heat dispersed through radiation will be smaller than the heat generated in the body, so thatascending of the body surface temperature is caused, and a function of keeping warm or cooling can be achieved.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a multilayer fabric and a preparation method thereof. Background technique [0002] Clothes, an ancient invention, play an important role in human beings without a doubt. However, what is interesting is that, starting from animal skins and leaves, to silk, cotton, and chemical fibers, although the materials of clothes are constantly updated, their basic functions have never changed, that is: to reduce heat dissipation and increase body surface temperature. [0003] The most important function of clothing is to maintain the normal temperature of the human body and make the human body feel comfortable. The heat transfer of clothing can basically be divided into two types: sensible heat transfer, that is, the heat transfer that can be generated by the difference between the temperature of the human body and the external environment, which is mainly completed through heat conductio...
