Title:
DEVICE FOR USING AIRFLOW UNDER CLOTHES TO EVALUATE THERMAL PROTECTION PERFORMANCE
Document Type and Number:
WIPO Patent Application WO/2024/031951
Kind Code:
A1
Abstract:
A device for using an airflow under clothes to evaluate the thermal protection performance of fabric. The device comprises a control system (1) for providing a heat source, a cylindrical skin simulator (9), and a monitoring system for an airflow under clothes (14), wherein an upper end of the cylindrical skin simulator (9) is provided with fabric clamping devices (11) that are evenly distributed, a sliding rail (12) is arranged on each fabric clamping device (11), and the sliding rail (12) is fixed to the cylindrical skin simulator (9); a skin simulation sensor (10) is embedded in a surface of the cylindrical skin simulator (9), and the skin simulation sensor (10) is electrically connected to a data acquisition and processing system (17); the surface of the cylindrical skin simulator (9) is provided with a fabric warp-direction thermal contraction scale meter (24); and the monitoring system for an airflow under clothes (14) is used for monitoring the speed and temperature of an airflow in a human body clothing system, and is connected to the data acquisition and processing system (17). The device can accurately predict the thermal protection performance of clothing on a dressed human body under different conditions of an airflow under clothes.
