The WATson heat loss devicequantifies the evaporative cooling of textiles

BÖNNIGHEIM (Germany) The 2019 published DIN SPEC 60015 “Quantitative measurement of the evaporative heat loss of smart textile materials for work, sports / outdoor and leisure”defines themeasuring procedure and requirements for textiles and clothing that claim to have a cooling effect. This already offers a market compliant standard. The next stage is to convert the method into an ISO standard.

WATson is the onlydevice worldwide thatcan quantitatively measurethe evaporative coolingability of a textile or textile system–for exampleduringactivity–andis already well received in the performance apparel and home textilesindustries. It measuresthe dynamic interaction of textiles and human thermal regulationwithcustomizableclimatic conditions and sweat rates. Only a 25x25 cm fabric sample is required for the WATson test, which providesdata on average cooling power, cooling power over time, fabric responseand dry time. The data is used for product development, benchmark comparisons, quality assurance and verified marketing claims. In addition tothemeasurementscenarios defined in DIN SPEC 60015, WATson’s setup can be tailored to meet specific requirements
