Self-adapting testing instrument for heat-moisture comfort performance of fabric and coupled testing method using same

Abstract

The invention relates to a self-adapting testing instrument and a testing method for heat-moisture comfort performance of fabric. The testing instrument comprises a testing main body and a testing accessory body, wherein the testing main body comprises a testing head; the testing head sequentially comprises a heating plate, a copper plate, a simulated skin, a simulated skin and a sample clamp clamped with a sample bottom to top; a temperature and humidity sensor is arranged between the sample and the simulated skin; a membrane couple is attached to the surface of the simulated skin device; multiple sweating micropores connected with a control valve of a peristaltic pump are disposed on the simulated skin device; the testing accessory body comprises a clothed human body heat physiological model module, a control module and a surface heat flow calculation module; the surface heat flow calculation module is used for calculating the surface heat flow according to the sweating amount of the sweating micropores and the temperature of the membrane couple; and the clothed human body heat physiological model module is used for real-time sending signals for controlling the peristaltic pump and the heating plate to the control module by taking the calculated surface heat flow as a boundary condition. The self-adapting testing instrument can simulate human body heat physiological characteristics changing along with the ambient change.

Description

technical field [0001] The invention relates to a clothing fabric heat and humidity comfort tester, in particular to an adaptive fabric heat and humidity comfort tester capable of simulating the thermal physiological characteristics of a human body and a coupling test method thereof. Background technique [0002] The heat and humidity comfort of fabric or clothing refers to the comprehensive balance of biothermodynamics achieved by the heat and humidity exchange between the human body and the environment after the human body is dressed in different climates, which can meet the requirements of the physiological state of the human body. The device for testing the heat and humidity comfort performance of fabrics is also called the fabric microclimate tester. The principle of the device is mainly to detect the heat and moisture transfer in the microclimate between the simulated human skin and the fabric sample by simulating the external environment and the thermophysiological pro...

Problems solved by technology

[0005] After searching, it is found that there is also a lack of a device or method to simulate the actual thermal physiological changes of the human body in different environments, so that the dynamic heat and moisture transfer characteristics of the fabric cannot be actually measured.
