And our science says that air is a poor conductor of heat and that’s why this trapped air acts as a thermal insulator so that the body doesn’t lose its heat in the surrounding environment due to temperature gradient. WebSo for the case between cotton and polyester, cotton does have a slightly lower thermal conductivity. Yet, when you combine cotton and polyester, you get even lower thermal conductivity ( Alay, Gode, Alkan, 2012 ). TL;DR: Polyester conducts heat better (less ideal) than cotton in their pure forms. fisher\u0027s towing indiana
