Embodiment 1

[0044] Such as Figure 1-3 Shown is the form of the fabric thermal insulation property tester under a kind of motion state provided by this method, and this tester contains three heating plates (11, 12, 13) for comparison, specifically, the tester provided by the present invention includes dynamic Simulator, described dynamic simulator is made of base (4), control board (1), reduction motor (3), crossbeam (5), counterweight plate (6), mannequin (7), the first test heating Plate (8), heating plate (9) for the second test, heating plate (10) for the third test, temperature sensor.

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

Embodiment 2

[0048] The fabrics to be tested (20, 21, 22) are woven cotton fabrics, and three identical samples of the fabrics to be tested are covered on the heating plate (8, 9, 10) for testing, and the three temperature sensors (14, 16, 18) Install on the surface of the heating plate for testing respectively, then place the temperature sensors (15, 17, 19) respectively on the control heating plates (11, 12, 13), adjust the sensor to the connecting point between the connecting head 2 and the crossbeam. The distance is 150mm, turn on the power switch of the control board 1, set the data analysis and display system to the receiving state, set the test heating plates (8, 9, 10) through the data analysis and display system control board on the PC, and control the heating plate The initial temperature of (11, 12, 13) is 37 degrees Celsius to simulate the normal body temperature of the human body. Set the speed of the geared motor 3 to 30 revolutions per minute, and set the running time to 600 ...

Embodiment 3

[0050] The fabrics to be tested (20, 21, 22) are knitted cotton fabrics, three identical samples of the fabric to be tested are covered on the heating plate (8, 9, 10) for testing, and the three temperature sensors (14, 16, 18 ) are respectively installed on the surface of the heating plate for testing, and then temperature sensors (15, 17, 19) are respectively placed on the control heating plate (11, 12, 13), and the distance between the sensor and the connecting point between the connecting head 2 and the beam is adjusted 150mm, turn on the power switch of the control board 1, set the data analysis and display system to the receiving state, set the test heating plates (8, 9, 10) through the data analysis and display system control board on the PC, and the control heating plate ( The initial temperature of 11, 12, 13) is 37 degrees Celsius to simulate the normal body temperature of the human body. Set the speed of the geared motor 3 to 30 revolutions per minute, and set the ru...

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...
