Abstract:

In order to explore the relationship between warm-cool feeling and the structure and mechanical properties of fabrics. The maximum transient thermal flow of 14 knitted underwear fabrics were tested by the KES-F7 tester. The influence factors were analyzed from the perspective of fabric density, fabric thickness and fabric mechanical properties on knitted fabrics contact thermal sensation. The results show that with tighter fabric structure, the still air content in the fabric will be lower, which would lead to the greater maximum transient heat flow of the fabric and stronger transient cool feeling. Fabric surface is smoother, skin and fabric contact area is larger, cool feeling will be stronger. The thicker of fabric thickness, the warm feeling will be intense. Correlation analysis of fabric maximum transient heat flow and mechanical property parameters shows that it is conducive to enhancing the fabric transient warmfeeling by reducing the fabric and skin contact area and improving the fabric bulkiness.
