The thermal insulation performance of clothing is mainly affected by two factors, one is the fabric of clothing, the other is the clothing's looseness. Therefore, the study on these two factors is of great help to the improvement and improvement of the thermal insulation performance of clothing. As a non-contact method for rapid and accurate temperature detection, infrared thermal camera can be used to test and evaluate the thermal conductivity and thermal insulation performance of clothing with different fabrics and different looseness, so as to improve the quality of inspection of clothing fabrics and looseness as well as the thermal insulation performance of clothing.

The research shows that the infrared thermal camera and computer processing method have high practical value in the textile material performance test and the clothing thermal comfort research, and the infrared thermal camera has a wide development prospect in the textile clothing field, which also has a good reference significance for the research in other fields.

Under the environment of 15℃ and 60% humidity, the custom of 1m/s was compared between windproof jeans and cotton jeans by human body model. The following figure shows the surface temperature of human body model taken by thermal imager after 3 hours.
