TEXTILE LAYERS ENABLING BACK REFLECTION OF HUMAN BODY THERMAL RADIATION
Original language description
The human body produces heat due to basal metabolism and specific physical activities. Up to 30% of this heat is emitted by radiation across the skin at wavelengths belonging to FIR region with maximum around 9.4 microns. Backscatter of this radiation from textile layer to human skin is supported by ceramic particles activated carbon particles, oxides and metals. Main aim of this contribution is description of preparation of special copper coated nonwoven polyester fibrous layers based on composite nonwovens MILIFE. The reflectance of the electromagnetic wave of these layers was tested by using of the integration ball principle. The mean total reflectance and corresponding 95% confidence intervals from five experimental spectra were calculated. The thermal insulation of copper coated MILIFE was characterized by infrared thermography measurement. The air and water vapor permeability were tested as well. It was found that the reflectance of copper coated MILIFE is increased by increasing of planar mas due to deposition of larger amount of copper.
