Fabric Drying Rate Tester AATCC201 Test
The fabric drying rate tester is used to test the fabric drying time and drying rate under the requirements of the AATCC201 standard to evaluate the quick-drying performance of the fabric. This method is applicable to all kinds of fabrics worn by people, including knitted, woven fabrics, non-woven fabrics, and fabrics taken from final products.
As a modern technology enterprise integrating R&D, manufacturing, sales, training, and service, Shanghai Qianshi Precision Electromechanical Technology Co., Ltd. is committed to delivering more testing instruments to the market, providing testing instruments for textiles, leather, combustion, automotive interior and exterior trims, material environmental climate aging, etc., and non-standard customization is also acceptable. Before purchase, targeted tests can be carried out according to customer requirements to ensure that the purchased instruments are applicable.
Test principle:
The tester simulates the drying process of sweat on the fabric when the human body sweats. The fabric is placed on a heating plate with a constant temperature of 37°, 0.2ml of water is dripped on the heating plate, and there is a wind speed of 1.5m/s on the fabric to dry the sample. The change in the temperature of the fabric is tested by an infrared temperature sensor to determine whether the fabric has been dried, and the drying speed is obtained according to the test drying time.
Test specimens:
1. Cut three specimens (15.0×15.0±0.5 cm) from each fabric sample from the right, middle, and left positions across the width of each tested specimen.
2. If testing garments or end products, take specimens from different parts of the garment, i.e. sleeves, back, and front.
3. If testing socks or socks, cut the specimens longitudinally and test each structure.
Test operation:
1. Turn on the temperature jacket controller for the flexible heater and fan, and stabilize the metal plate temperature at 37±1℃.
2. Using a hot wire anemometer, verify that the airflow on the plate is 1.5±0.5 m/s, and measure the airflow directly behind the infrared thermocouple probe.
3. Place the specimen on the metal and place the specimen for 5 minutes to equilibrate to the metal plate temperature. Place the side of the specimen next to the skin against the metal plate surface. Use a peel to fix the top edge of the specimen, close to the metal plate surface of the fan.
4. Place the IR thermocouple probe in the middle of the specimen 1.0 ± 0.1 cm above the specimen. It is helpful to have a mark on the metal plate to center the IR field of view of the thermocouple probe.
5. Start the recorder, lift the free end of the specimen (opposite the magnetic strip), and apply 0.200 ± 0.003 ml of water to the plate below the specimen directly below the IR thermocouple probe, reposition the specimen so that it is covered by the water drop, the start time is the time the specimen is in contact with the water.
6. Look at the specimen to determine the wicking wheel generated by the water, and confirm that the water is not wicking to the edge of the specimen, if it is wicking to the edge of the specimen then use a larger specimen or reduce the volume.
7. Collect and record the temperature every second until the temperature returns to the initial temperature. Repeat the test on additional specimens.
