Providing thermal exchange when designing special clothing

Abstract

This paper considers the issues of establishing the relationship between the properties of fabric, clothing design and the comfort of clothing; communication of the size of the human body, allowance for free fitting, modern design when developing the design of clothing; connection of the allowance for free fitting with a suitable air gap. A diagram is given that characterizes the dependence of the comfort of clothing on its design and properties of fabrics. A mathematical model of the processes of air exchange in the underwear space is considered, which will allow obtaining more complete information and establishing more stringent dependences of the allowance on various factors affecting its value. The numerical value of the allowances for some parameters of the environment, which characterizes the hot climate, is obtained. An analytical method for calculating the allowance for free fitting is considered. The fact is stated that for the air exchange process a mathematical model has been obtained that allows one to determine the concentration of H2O or CO2 in the space under the space during diffusion air exchange, and that the mathematical model of complex convective- diffusion air exchange is based on the equation of the material balance of the transferred component for the space available; and that the curves were used to determine the influence of product design, fabric properties and environmental parameters on the free-fit allowance.
