Temperature regulation in textiles is a key aspect of comfortability. When exercising, our bodies release thermal energy that must be absorbed by our surroundings to help maintain a comfortable temperature. However, if the selected fabric is not effective at absorbing this heat, it can have negative effects on our performance and comfort. When designing active wear, mattresses, diapers, and blankets, the selected materials ability to transfer and exchange that thermal input is crucial to the product’s overall performance. A key attribute in developing such products is the material’s cool touch or warm feel, which is quantified as the material’s thermal effusivity.
Thermal effusivity is an intrinsic material property which describes the ability of two materials in contact to exchange thermal energy. It is what many industries use to describe a materials warm/cool feel. Quantifying thermal effusivity of bedding materials and other textiles is easily accomplished using C-Therm’s Modified Transient Plane Source (MTPS) with Guard-Ring™ technology. Not only is this the sole method that conforms to ASTM D7984 but being a single-sided measurement device, it allows for representative testing conditions under varying force loads, temperature, and humidity conditions.
Whether developing the next generation of textile technology or simply looking to better quantify the performance of materials in general, this webinar will highlight the use of the MTPS for characterization of a range of common materials. Data collected on samples such as fabric, mattresses, active wear will be presented alongside work from academia and industry.
This webinar will air on January 16, 2025 @ 2:00PM GMT-4.
