Example Embodiment

[0043] Example 1

[0044] Such as Figure 1-3 Shown is the form of a fabric thermal insulation performance tester provided by this method in a motion state. The tester contains three control heating plates (11, 12, 13). Specifically, the tester provided by the present invention includes dynamic Simulator, the dynamic simulator consists of a base (4), a control board (1), a geared motor (3), a beam (5), a counterweight plate (6), a humanoid model (7), and a heating for the first test Plate (8), heating plate for second test (9), heating plate for third test (10), temperature sensor.

[0045] The geared motor (3) has an external power supply and is fixed inside the base (4). The speed setting range is 10 to 1000 revolutions per minute. The purpose is to simulate different environmental wind speeds by changing the speed to study and test fabrics under different conditions. The main shaft of the geared motor is fixedly connected to the connector (2), and the other end of the connecto...

Abstract

The invention relates to a fabric insulation tester under a motion state. The tester comprises a main component: a dynamic simulator, wherein the dynamic simulator comprises a base, a control panel, agear motor, a cross beam, a humanoid model, a counterweight plate, a heating plate for test, a heating plate for contrast and a sensor. Two heating plates are arranged on each surface of the humanoidmodel of a test plate, one heating plate is used as a heating platform for test and the other heating plate is used as a heating platform for contrast. Through the tester, the fabric insulation performance at different motion states and different environments can be tested through experiments, and data of a contrast sample platform and a test sample platform can be obtained at the same time; andthe measured indexes are more accurate and objective, so that the errors are reduced. The tester is simple in structure and convenient in test, has a great application prospect, and is suitable for insulation performance detection of various fabrics.

Description

technical field [0001] The invention relates to a dynamic tester for fabric thermal insulation performance, which belongs to the textile measuring technology. Background technique [0002] The thermal insulation performance of fabrics belongs to the study of thermal comfort of fabrics. As a subjective feeling, thermal comfort also has a great impact on people's daily life and work, so the research on the thermal insulation performance of fabrics is of great significance. [0003] There are many instruments currently used to study the thermal comfort performance of fabrics. For example, the heat and moisture transfer performance of fabrics in the article "A New Type of Fabric Heat and Moisture Transfer Performance Tester" in the fourth issue of "Journal of Tianjin Textile Engineering Institute" in 1998 The tester uses an artificial skin that can quickly diffuse water, and sticks it closely to the heating copper plate. Through temperature and humidity sensors, under the condit...
