Test Principle of Instant Cool Feeling Tester for Textiles

The instant textile freshness tester is used to test the freshness of pajamas, bedding, fabrics and underwear, and can also measure thermal conductivity. It is a test equipment independently developed and produced by our company qisnun Precision Electromechanical Technology Co., Ltd. Complete after-sales service.

Complies with:

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

Test principle:

Under the specified test environment conditions, the temperature is higher than the thermal sensing of the sample plate is in contact with the sample, measures the temperature change of the thermal sensing plate with time, and calculates its contact cooling coefficient (qmax), which can characterize the cooling performance of the sample at the time of contact. The greater the value of qmaxe, the skin feels a sensation of freshness. The higher the degree, the smaller the value, the weaker the ski feels.

Technical parameters:

1. Heating plate temperature range: room temperature +5℃～48℃;

2. Heating plate, heat plate thermal detection, sample loading Taiwan temperature display resolution: 0.1°C;

3. Thermal detection board response time: <0.2s;

4. Test time: adjustable from 0.1s to 99999.9s;

5. Low temperature constant temperature bath temperature range: -5℃～90℃;

6. Online software control, test curve in real time ;

7. With printer interface;

8. Power supply: 220V, 50Hz, 150W.
