Textile thermal resistance tester
Category：Other
Introduction
The Textile Thermal Resistance Tester measures the ability of textiles to resist heat transfer, providing the thermal resistance value. It simulates the heat exchange process between the human body and the environment. The principle is based on the three fundamental modes of heat transfer: conduction, convection, and radiation. By controlling temperature difference and airflow conditions, the tester monitors temperature changes on both sides of the textile sample to calculate thermal resistance.
The instrument typically consists of a constant-temperature heat source (simulating the human body), a cooling plate (simulating the external environment), and a sample clamped between them. Heat from the source is conducted through the textile to the cooling plate. Simulated airflow creates a realistic heat exchange environment, while high-precision sensors record temperature changes. Data is then processed using specialized algorithms to calculate the textile’s thermal resistance.
