The textile contact instant coolness tester is used to test the coolness of pajamas, bedding, fabrics, and underwear, and can also measure thermal conductivity.

Compliant with standards:

GB/T 35263-2017, FTTS-FA-019, FZT 73067-2020 and other standards.

Testing principle:

Under the specified test environment conditions, the heat detection plate with a temperature higher than the sample is placed in contact with the sample. The temperature change of the heat detection plate over time is measured, and its contact coolness coefficient (qmax) is calculated to characterize the instantaneous coolness performance of the sample. The larger the qmax value, the stronger the skin feels the coolness, while the smaller the value, the weaker the skin feels the coolness.
