Evaluating the Clothing Insulation of T-Shirts Using Thermal Manikin

Thermal insulation is crucial for retaining body heat and ensuring warmth in cooler environments. Fabrics with higher thermal insulation effectively trap air close to the skin, creating a barrier that minimizes heat loss. This study explores the thermal insulation properties of T-shirts, which are among the most used clothing items worldwide. It also investigates their air permeability, considering factors such as fabric type, density and thickness. Five cotton-type T-shirts are measured using thermal manikin and air permeability tester. The study examines the relationship between the heat and air transfer capabilities of the knitted fabrics used in their production and some typical characteristics of the fabrics.
