Description

Technical Field

[0001] The utility model relates to a textile material hygroscopicity testing device, belonging to the technical field of textile material hygroscopicity testing. Background Art

[0002] The research on the liquid absorption performance of textile materials, especially the water absorption performance, has always received a lot of attention worldwide. The commonly used methods are: using a high-speed camera to shoot the liquid transfer process and using image processing to calculate the liquid transfer rate; using penetrating particles such as α particles and neutrons to evaluate the transfer characteristics of liquids in textiles by measuring the intensity before and after penetration. High-speed camera shooting is complicated, and the image processing results are related to the edge sharpening algorithm, image binarization algorithm, etc., and the results are affected by many factors; penetrating particles will affect the health of operators and are difficult to popularize.

[0003] The most widely used dynamic moisture management instrument (MMT) was developed by Professor Li Yi's research team at the Hong Kong Polytechnic University in 2005 and accepted by the AATCC standard, becoming a standard instrument for studying the water absorption properties of textile materials. However, the copper ring in the instrument needs to be in direct contact with the textile and cause changes in the surface structure of the textile, thus affecting the measurement results. In addition, the instrument can only be used to test liquids that can cause changes in the resistance of textile materials, and is not suitable for most edible or industrial oils and certain organic solutions.

[0004] China Invention Patent Publication No. CN104931393A discloses a device and method for evaluating the liquid absorption performance of textile materials, and mentions a non-contact measurement device based on Beer-Lambert's law. The device places an infrared emitting end and a receiving end on both sides of the textile. When the liquid expands, it will cause the change of the infrared intensity received by the receiving end, thereby calculating indicators such as the liquid transfer rate and the maximum absorption amount. China Invention Patent Publication No. CN113514368A discloses a fiber array dynamic liquid absorption tester, which also uses infrared laser to irradiate textiles and collects reflection signals to further measure the transfer of liquid.

[0005] The above existing methods, whether contact measurement or non-contact measurement, cannot simulate the wearing state of textiles. When the human body is wearing clothing, the liquid does not always drip in a direction perpendicular to the surface of the textile, and the textile is not always in a horizontal plane. For example, textiles on the legs, hips and elbows of the human body are cylindrical. The tilt and shape change of the textile will directly affect the measurement results. Summary of the invention
