Full text | Abstract: The article justifies the use of calculative determination of the heat transfer coefficient k, on the basis of immutable parameters of the textile layer such as thermal conductivity and thickness. A method of elaborating the heat transfer coefficient is described, and examples of calculations are presented for randomly selected samples of clothing woven fabrics. It was proved possible to make a calculative estimation of the influence of changes on the parameters of the textile layer, as well as the conditions of use on the value of the heat transfer coefficient. No estimation of the woven fabrics tested from the point of view of their properties was carried out. A brief description of a device for measuring the thermal conductivity coefficient and the heat transfer coefficient of flat textile products is presented. |
