Abstract

The invention relates to a textile fabric cool function testing device and an assessment method. The testing device comprises a testing environment constant-temperature constant-humidity chamber, an experiment table, a mainframe and a computer. The constant-temperature constant-humidity chamber comprises a refrigerating system, a humidifying system and a heating temperature-control system. The experiment table comprises a testing board, a heating plate and a surrounding protective heat-insulation plate, and the testing board is provided with a temperature sensor. The mainframe comprises an internal thyristor regulation heater and a data acquisition system. A textile fabric cool function testing method mainly includes fabric dry and wet state heating curve testing. Comprehensive characterization of fabric cool functions including heat transfer, moisture diffusion / evaporative heat dissipation, phase-change heat absorption and the like can be realized.

Description

technical field [0001] The invention relates to a test device for fabric cool function and a fabric cool evaluation method based on the test device, belonging to the field of textile testing. Background technique [0002] With the improvement of people's living standards, the seasonality, functionality and comfort of clothing have received great attention. Winter clothing is required to generate heat and keep warm and comfortable, while summer clothing must meet the functional requirements of moisture absorption, quick drying, cooling and heat dissipation. The good thermal conductivity, high moisture conductivity, and phase change heat storage of the fabric all help the fabric to achieve a good cooling function. The good thermal conductivity of the fabric enables the heat generated by the human body to be quickly transferred to the outside; the rapid evaporation of water after the human body sweats can take away a large amount of heat to achieve the purpose of cooling; the ...
