These indexes describe the fabric's thermal properties during the heated process. The heat insulation ratio preferably manifests fabric's insulation property; the difference of calefactive ratio describes dynamic conditions average calefactive case; effective thermal conductivity and compound thermal resistance are mainly considering the wholly testing characteristics and describing the compound thermal property; the response time expresses the time of step response during dynamic testing process. 3. Dynamic heat transmitting properties of fabrics and warmth retention testing methods have been developed; many different textile materials are used for actual test, and the data are analyzed, illustrated, and compared.
