Description

technical field [0001] The invention belongs to the field of textile and weaving, in particular to an infrared heat storage functional fiber and a preparation method thereof. Background technique [0002] Long-term exposure to a low temperature environment will cause damage to the human body. In order to achieve the purpose of keeping warm and comfortable, thermal clothing is usually divided into passive warmth and active warmth. Passive warmth is to increase the thermal resistance of clothing to keep warm, such as adding clothes, but In this way, the wearer is bulky, inflexible, and unable to keep warm for a long time. Active thermal clothing can be divided into solar heating clothing, chemical energy heating clothing, phase change material heating clothing and electric heating clothing. One is to use solar thermal storage materials to absorb visible light and near-infrared rays of solar radiation and reflect human body thermal radiation. Chemical energy heating clothing ...
