Abstract

Abstract The human body constantly produces thermal electromagnetic radiation with a maximum of about 10 µm. This thermal radiation has a number of positive effects on the human body and, in addition, allows the insulation under clothing to be improved under extreme climatic conditions, causing a significant reduction in ambient temperature. With so-called far-infrared (FIR) textiles, it is possible to ensure the reflection of thermal radiation back to the human body. In the first part of this review, the generation of heat by the human body and its propagation by radiation through the skin are comprehensively explained. The thermal characteristics of the individual skin layers as an emitter of infrared radiation are given. The second part discusses the basic preparation methods of FIR textiles. Suitable particle systems are described based on metals and their oxides, porous carbon, and special ceramics. Modification of the fiber phase (especially the fineness of the fibers and the porosity of the fabric) in combination with the surface coating of metals is also used for their health-promoting effects. The main manufacturers of FIR textiles and their typical products are mentioned.

反映人体产生的FIR的纺织品综述

人体不断产生热电磁辐射，最大辐射强度约为10µm。这种热辐射对人体有许多积极的影响，此外，在极端气候条件下，可以改善衣服的绝缘性，从而显著降低环境温度。有了所谓的远红外(FIR)纺织品，就有可能保证热辐射反射回人体。在本文的第一部分中，全面阐述了人体产生热量及其通过皮肤辐射传播的原理。给出了单个皮肤层作为红外辐射发射器的热特性。第二部分论述了FIR纺织品的基本制备方法。描述了基于金属及其氧化物、多孔碳和特殊陶瓷的合适颗粒体系。纤维相的改性(特别是纤维的细度和织物的孔隙度)与金属表面涂层相结合也被用于促进健康的效果。介绍了FIR纺织品的主要生产厂家及其典型产品。
