FAQ

1. How does the "6-station independent control" benefit the testing process?

It allows you to run different types of fabrics or different test parameters on each station at the same time. You can start or stop any of the six tests without interfering with the others, which significantly increases laboratory efficiency compared to single-station units.

2. Why is a resolution of 0.001g necessary for this test?

Quick-dry fabrics often evaporate moisture in very small increments. To calculate an accurate "rate," the sensor must be sensitive enough to detect minute changes in mass over short intervals (e.g., 1 minute), which is impossible with standard 0.01g balances.

3. What environmental factors can affect the test results?

Evaporation is highly sensitive to ambient temperature and humidity. For standardized results, you should operate the tester in a climate-controlled room. Even minor fluctuations in air speed can alter the drying rate.

4. Can this machine test fabrics with very high water absorption, like heavy towels?

Yes, as long as the total sample weight (fabric + absorbed water) does not exceed 100g. For exceptionally heavy materials, you may need to adjust the amount of water applied to remain within the sensor's measurement range.

5. How is the "Evaporation Rate" actually calculated by the software?

The software performs a linear regression or differential calculation of the weight loss over time ($\Delta \text{Mass} / \Delta \text{Time}$). It identifies the constant-rate drying period to provide the most accurate assessment of the fabric's functional performance.
