Textile Drying Rate Tester

Abstract

The invention belongs to the field of testing machines, in particular to a testing machine for testing the drying speed of textiles. The combination of the upper cover and the base forms a drying chamber for air circulation; a heating plate for providing heat is installed on the side of the base close to the drying chamber; the heating plate is covered with a heat conducting plate, which is used to transfer heat evenly and quickly to the Textiles; the water outlet of the pump is installed on the upper surface of the heat conduction plate, and the pump is used to send test water to the heat conduction plate; the water injection solenoid valve is installed on the water outlet pipeline of the pump, and the water injection solenoid valve is used to control the flow and timing of the water delivered by the pump ; A temperature sensor is installed at the water outlet of the pump, and the temperature sensor is used to detect the temperature of the textile. The textile drying rate testing machine simulates the temperature of the human body through the heating plate and the heat transfer plate. At the same time, the test water is passed into the textile through the pump and the temperature of the textile is detected through the temperature sensor, so that the textile drying speed test is completely automated.

Description

technical field

[0001] The invention belongs to the field of testing machines, in particular to a testing machine for testing the drying speed of textiles. Background technique

[0002] The textile drying rate test adopts the American AATCC201-2013 standard. The usual method is manual operation. The fabric surface has a horizontal airflow of 1.5 m / s generated by a vertical bellows and a guide plate. The fabric surface temperature is passed through a non-contact infrared temperature sensor. To measure, the airflow velocity is monitored by a hot-wire anemometer. During the test, a fabric sample needs to be placed on a hot plate with a constant temperature of 37°C, 0.200±0.003mL of water is dropped on the hot plate under the center of the fabric, and the temperature change of the fabric is monitored.

[0003] The current test method is to lift the fabric on one side, cover the fabric immediately after water drips from the center of the hot plate and start timing. A temperatur...
