Hohenstein Webinar: Science vs. Fiction - Verifying the Cooling Power of Performance Fabrics

BÖNNIGHEIM (tm) Dr. Jan Beringer will focus on the science behind cooling effects and the methods to quantify the cooling power of performance fabrics including WATson, Hohenstein’s proprietary technology that accurately measures a fabric’s claimed evaporative heat loss, i.e., cooling power. The webinar will be held at12:00 Noon EST on Wednesday, April 26. Online registration is available at https://attendee.gotowebinar.com/register/6971172382719022594.

Clothing physiology, the study of the interaction between clothing, the body, and the ambient climate, provides the science for quantifying comfort. With over sixty years of experience, Hohenstein experts are thought leaders in the clothing physiology field. They have developed many proprietary technologies to define and measure specific thermal comfort factors. Hohenstein works with companies to test textiles for these factors in order to determine optimal product design and to verify marketing claims such as for cooling effects and moisture management.

In response to high client demand for reliable methods to quantify cooling effects, Hohenstein recently has added a second WATson evaporative heat loss tester and doubled their testing capacity for verifying the thermophysiological cooling power of performance fabrics. WATson precisely measures critical attributes that affect a fabric’s thermal cooling performance. WATson models the interactions of textiles and human skin, i.e., human thermoregulation, in a variety of ambient climates. The system analyzes minute evaporative heat loss changes across the skin’s surface and accurately quantifies the cooling power the textile provides. WATson technology requires a 10”x10” fabric sample to analyze performance for product development, quality assurance, and marketing claims.

“The first WATson system we designed has been booked far beyond its capacity recently,” Beringer says. “With the addition of the second WATson system, our lead times are back to normal and we can quickly provide clients with the data they need to confirm the cooling effect of their product in the specific climate scenarios most relevant to the product’s intended use.”

In addition to the established “standard apparel protocol” for performance fabrics that nearly all customers use to ensure comparability, the WATson system can replicate a wide variety of custom climates and set-ups while measuring the textile’s ability to manage moisture and influence the evaporative heat loss. The result is a comprehensive report that reliably measures how products will perform once consumers wear them in real life.
