Embodiment 1

[0036] A tester for quickly testing the thermal insulation performance of fabrics. A test heating plate 2 and a reference heating plate 3 are respectively installed on the upper part of the instrument testing platform 1, and first heat insulation and heat preservation plates are respectively installed around the test heating plate 2 and the reference heating plate 3. 5. The second thermal insulation board 6 is equipped with an airflow generator 7 on one side of the test heating plate 2 and the reference heating plate 3. The temperature acquisition control module 4 collects the heating plate temperature sensor 8, the reference heating plate temperature sensor 9, the fabric The temperature of the temperature sensor 10 and the air temperature sensor 11, the temperature acquisition control module 4 controls the power on and off of the test heating plate 2 and the reference heating plate 3.

[0037] Center of test heating plate 2, reference heating plate 3, first insulation panel 5,...

Embodiment 2

[0040] Take a pure cotton fabric with an area of ​​20cm*20cm, place it on the test heating plate, under the fabric temperature sensor, turn on the test heating plate, and start heating with reference to the heating plate until it reaches 36 degrees Celsius, control the test heating plate through the temperature acquisition control module, and refer to the heating Turn on and off the power of the board to keep the temperature constant. The temperature of the test heating board and the reference heating board is the same as that of the surrounding heat insulation board. The temperature of the reference heating board is diffused through the air, and the temperature of the test heating board is diffused through the fabric, and no airflow occurs. The average power required for the test heating plate and the reference heating plate to maintain a constant temperature within 10 minutes is 2.08W and 2.36W respectively, and the heat preservation rate of cotton fabric is calculated by the ...

Embodiment 3

[0042] Take a pure cotton fabric with an area of ​​20cm*20cm, place it on the test heating plate, under the fabric temperature sensor, turn on the test heating plate, and start heating with reference to the heating plate until it reaches 36 degrees Celsius, control the test heating plate through the temperature acquisition control module, and refer to the heating Turn on and off the power of the board to keep the temperature constant. The temperature of the test heating board and the reference heating board is the same as that of the surrounding heat insulation board. The temperature of the reference heating board is diffused through the air, and the temperature of the test heating board is diffused through the fabric. Turn on the airflow generator , select the wind speed to be 2 meters per second, the average power required by the test heating plate and the reference heating plate to maintain a constant temperature within 10 minutes is 3.48W, 4.56W respectively, and the cotton ...

Abstract

The invention relates to a tester for rapidly testing a heat-insulating property of a fabric, and belongs to the technical field of textile measurement. The tester mainly comprises two heating plates,a temperature acquisition and control module and an air flow generation module, and the two heating plates are placed on the same horizontal plane. The tester for rapidly testing the heat-insulatingproperty of the fabric is reasonable in structure and convenient to operate and use. By the tester for rapidly testing the heat-insulation property of the fabric, the heat-insulation property of the fabric can be tested rapidly, the heat-insulation index of the fabric can further be tested in an open environment, and the theoretical basis is provided for researching and evaluating heat transfer performance indexes of the fabric.

Description

technical field [0001] The invention belongs to the technical field of textile measurement, and in particular relates to a tester for rapidly testing fabric thermal insulation performance. Background technique [0002] The thermal insulation performance of fabrics is one of the important wearing properties, and functional textiles with thermal insulation as the main feature will be extended to a wider range of fields. Therefore, the test of fabric thermal insulation performance is more and more valued and widely used by textile testing institutions, and at the same time, higher requirements are put forward for thermal insulation instruments for testing fabric thermal insulation performance. [0003] At present, there are certain researches on the test of fabric thermal insulation performance, such as "New flat-type fabric thermal insulation instrument" in the article "Development and Application of New Flat-type Fabric Thermal Insulation Instrument" in the 9th issue of Knitt...
