Thermal and Moisture Comfort Properties of Down Jacket Fabrics

In order to study the thermal and moisture comfort properties of down jacket fabrics, 20 popular down jacket fabrics were selected from the market. The basic specifications of the samples were tested,and thermal and moisture performance tests were conducted. The obtained thermal and moisture indicators were analyzed, and then combined with the subjective evaluation results to obtain the regression equation for the evaluation of the comprehensive thermal and moisture comfort of down jacket fabrics. The air permeability, the thermal resistance, the warm and cold feeling and the moisture permeability were tested, and the results were divided into 5 levels. The results showed that the consistency of the air permeability and the moisture permeability of down jacket fabrics studied was better, and the thermal insulation of the down jacket fabrics with coating was better. The thickness of the down jacket fabrics had an effect on the warm and cold feeling of instant contact, and the consistency of subjective and objective warm and cold feeling was better. The obtained comprehensive evaluation equation of the thermal and moisture comfort has certain guiding significance for the thermal and moisture comfort of down jacket fabrics.
