The textile contact instantaneous coolness tester

Application Scope

The textile contact instantaneous coolness tester is used to test the cool feeling of pajamas, bedding, fabrics, underwear, etc. It can also measure the thermal conductivity.

Applicable Standards

It complies with standards such as GB/T 35263 - 2017, FTTS - FA - 019, FZT 73067 - 2020, etc.

Test Principle

Under the specified test environmental conditions, a hot detection plate with a temperature higher than that of the sample is brought into contact with the sample. The change in the temperature of the hot detection plate over time is measured, and the contact coolness coefficient (qmax) is calculated. This can characterize the contact instantaneous coolness performance of the sample. The larger the qmax value, the stronger the cool feeling perceived by the skin; the smaller the qmax value, the weaker the cool feeling perceived by the skin.
