DryRate 201
Precision Drying Rate Measurement Made Simple
The popularity of moisture management products aimed at making the wearer feel dry and comfortable is soaring. State-ofthe-art measurement
and analysis of the drying characteristics of fabrics in the textile sector is essential. DryRate 201 is a fully automated and advanced instrument
with a heated metal plate, which simulates human skin starting to perspire at 37°C, that determines the drying rate based on evaporation rate from
the fabric. The instrument comes with a touch screen controller for setting parameters, monitoring testing status, and reading final results.
For more detailed analysis, testing data can be transmitted to a computer for real-time test curve display.
Testing Principle
Based on the principle of a wetted fabric against a heat source with air flow,
the evaporation of water will remove heat to reduce the surface temperature.
Detecting the temperature of the fabric surface accurately determines
whether the textile has become completely dry.
For the fully automated testing mode, the operator simply places the sample
in the test area, and the instrument will automatically run the test including
water dispensing and generate the results once completed. The operator can
change the amount of water and air flow through the testing parameters.
The manual test mode allows for the same change of air flow through the test
settings with the added ability to perform manual water dosing as described
in the AATCC 201 Test Method.
All test results are included in test reports which can be displayed either
directly on the instrument screen or on a connected computer for further
analysis and comparison to previous tests.
