Description

Technical Field

[0001] This utility model relates to the field of fabric performance testing technology, and in particular to a fabric moisture absorption and heat generation performance testing device. Background Technology

[0002] As people's demands for textiles increase, single-fiber fabrics can no longer meet their needs. For autumn and winter fabrics, the requirement is typically for materials that can absorb moisture and generate heat. Moisture-wicking and heat-generating fabrics are materials that can absorb human sweat and convert it into heat energy. They are widely used in sportswear and other fields.

[0003] The moisture absorption and heat generation properties of fabrics, referring to the ability of certain fibers to absorb moisture and convert it into heat energy, are increasingly recognized by the market. Currently, tests on the moisture absorption and heat generation properties of fabrics often only test one textile sample at a time, resulting in low efficiency and incomparable results. Furthermore, the accuracy of the tests is significantly affected by the temperature and humidity of the testing environment. Temperature influences the fabric's moisture absorption capacity; large temperature variations can cause the fabric to absorb or release moisture at different rates—for example, high temperatures may accelerate evaporation while low temperatures may slow it down, leading to differences in moisture absorption. Similarly, fluctuations in ambient humidity also affect the accuracy of the test results. Summary of the Invention

[0004] To address the shortcomings of the existing technologies, a fabric moisture absorption and heat generation performance testing device is provided. This device tests the moisture absorption and heat generation performance of fabrics in a constant temperature and humidity environment. Compared with non-constant temperature and humidity environments, it can eliminate the influence of temperature and humidity changes on the test results. Under stable temperature and humidity conditions, the performance of the fabric is more consistent, making the test results more accurate and reliable. Furthermore, it can test the moisture absorption and heat generation performance of multiple textile fabric samples at the same time, making the test results comparable.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is a fabric moisture absorption and heat generation performance testing device, including a constant temperature and humidity chamber, a support frame inside the constant temperature and humidity chamber, an experimental platform for measuring the moisture absorption and heat generation performance of the fabric on the support frame, and an adjustment component for adjusting the height of the support frame on the inner wall of the constant temperature and humidity chamber.

[0006] The aforementioned fabric moisture absorption and heat generation performance testing equipment includes a support frame consisting of four rods connected end to end. Multiple support ribs are spaced apart on the upper surface of the support frame, and multiple bottom ribs are spaced apart below the support ribs.

[0007] The aforementioned fabric moisture absorption and heat generation performance testing equipment includes an adjustment component comprising four longitudinal plates arranged on the corresponding two inner walls of a constant temperature and humidity chamber. Each longitudinal plate has multiple fixing slots along its height direction, and each longitudinal plate has an insert plate for connecting to the fixing slots.

[0008] The aforementioned fabric moisture absorption and heat generation performance testing equipment has a support plate with a right-angled triangle cross-section at the bottom of the insertion plate.

[0009] The aforementioned fabric moisture absorption and heat generation performance testing equipment includes a test bench comprising a base plate, a test frame on the base plate, a mounting plate on the top of the test frame, multiple holes on the mounting plate, a support plate above each hole for supporting the fabric, a water inlet hole communicating with the hole on each support plate, a cavity with open ends for pressing down the fabric on each support plate, a pressure plate above the cavity for pressing down the cavity, and a vent hole on the pressure plate. A test area is formed between the heat insulation sheet and the support plate. The equipment also includes a water inlet mechanism communicating with the holes, a water holding device communicating with the water inlet mechanism, and a water supply mechanism communicating with the water holding device. Temperature measuring strips are also provided on each support plate.

[0010] The aforementioned fabric moisture absorption and heat generation performance testing equipment includes a water inlet mechanism comprising a fixed plate mounted on a test frame, multiple flow meters mounted on the fixed plate, a water inlet pipe with one end connected to the hole and the other end connected to the outlet of the flow meter located below each hole, and a speed control switch connected to the inlet of each flow meter.

[0011] The aforementioned fabric moisture absorption and heat generation performance testing equipment includes a water-holding device comprising a placement box mounted on a base plate, wherein a spring ring can is slidably inserted into the interior of the placement box, and two corresponding connectors are fixedly connected to the upper surface of the spring ring can.

[0012] The aforementioned fabric moisture absorption and heat generation performance testing equipment includes a water supply mechanism comprising multiple air pumps mounted on a base plate. The output end of each air pump is connected to a spring ring tank, and drain pipes, respectively connected to both ends of a speed control switch, are inserted into the interior of two connectors.

[0013] The aforementioned fabric moisture absorption and heat generation performance testing equipment has heat insulation sheets in each cavity, and the heat insulation sheets have through holes at the center.

[0014] The aforementioned fabric moisture absorption and heat generation performance testing equipment has four holes arranged in a rectangular array on the mounting plate; and four water inlet holes arranged in a rectangular array on the support plate.

[0015] The beneficial effects of this utility model's fabric moisture absorption and heat generation performance testing device are that by setting the experimental platform inside a constant temperature and humidity chamber, and conducting the test in a constant temperature and humidity environment, the influence of temperature and humidity changes on the test results can be eliminated compared to a non-constant temperature and humidity environment. Under stable temperature and humidity conditions, the fabric's performance is more consistent, making the test results more accurate and reliable. Eliminating the interference of temperature and humidity changes on the test results also helps to ensure that all test samples are tested under the same conditions, thereby facilitating the comparison and analysis of test results and improving the comparability of test results.

[0016] Textiles are often subjected to specific temperature and humidity conditions during actual use. Testing under simulated conditions can more realistically reflect the fabric's performance in real-world environments. This is especially true for moisture-absorbing and heat-generating textiles such as knitted underwear, shirts, and socks, where the fabric is in direct contact with human skin; the heat and humidity emitted by the body significantly impact the fabric's performance. Therefore, testing in a constant temperature and humidity environment helps to more accurately evaluate the fabric's moisture-absorbing and heat-generating properties.

[0017] The height of the test bench can be adjusted by an adjustment component on the inner wall of the constant temperature and humidity chamber, which makes it convenient for testers of different heights to place the test fabric. Attached Figure Description

[0028] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-9 As shown, a fabric moisture absorption and heat generation performance testing device includes a constant temperature and humidity chamber 21. A support frame is provided inside the chamber 21, and an experimental platform for measuring the fabric's moisture absorption and heat generation performance is mounted on the support frame. An adjustment component for adjusting the height of the support frame is provided on the inner wall of the chamber 21. A viewing window 23 is provided on the door 22 of the chamber 21. The constant temperature and humidity chamber 21 is a common device in the art and will not be described in detail here.

[0030] The support frame includes a support frame composed of four rods 24 connected end to end. Multiple support ribs 25 are spaced apart on the upper surface of the support frame, and multiple bottom ribs 26 are spaced apart below the support ribs 25.

[0031] The adjustment assembly includes four longitudinal plates 27 mounted on two corresponding inner walls of the constant temperature and humidity chamber 23. Each longitudinal plate 27 has multiple fixing slots 28 along its height, and each longitudinal plate 27 has an insert plate 29 for engaging with the fixing slots 28. A support plate 30 with a right-angled triangular cross-section is located at the bottom of the insert plate 29. By providing an adjustment assembly on the inner wall of the constant temperature and humidity chamber for adjusting the height of the support frame, the height of the experimental platform can be adjusted, facilitating the placement of test fabrics by testers of different heights.

[0032] The experimental platform includes a base plate 1, a test rack on the base plate 1, a mounting plate 2 on the top of the test rack, multiple holes 3 on the mounting plate 2, a support plate 4 for supporting the fabric above each hole 3, a water inlet hole 5 communicating with the hole 3 on each support plate 4, a cavity 6 with open ends for pressing down the fabric on each support plate 4, a pressure plate 19 for pressing down the cavity 6 above the cavity 6, the pressure plate 19 having a vent hole, and the cavity 6 may be made of glass.

[0033] It also includes a water inlet mechanism connected to the hole 3, a water holding device connected to the water inlet mechanism, and a water supply mechanism connected to the water holding device. Temperature measuring strips 20 are also provided on each support plate 4; the measuring points of the temperature measuring strips can be located at the center of the support plate 4. There are four holes 3 arranged in a rectangular array on the mounting plate 2. There are four water inlet holes 5 arranged in a rectangular array on the support plate 4. By providing a cavity 6 with open ends to hold the fabric in place, the fabric is made more stable during measurement, preventing displacement of the fabric when water enters through the water inlet mechanism.

[0034] By setting the test bench inside a constant temperature and humidity chamber and conducting tests in a constant temperature and humidity environment, the influence of temperature and humidity changes on the test results can be eliminated. Under stable temperature and humidity conditions, the fabric performance is more consistent, making the test results more accurate and reliable. Eliminating the interference of temperature and humidity changes on the test results, and by setting multiple holes and water inlets, it is also helpful to ensure that all test samples are tested under the same conditions, which facilitates comparison and analysis of test results and improves the comparability of test results.

[0035] The water inlet mechanism includes a fixed plate 7 mounted on a test frame, a plurality of flow meters 8 mounted on the fixed plate 7, and a water inlet pipe 9 below each hole 3, one end of which is connected to the hole 3 and the other end of which is connected to the outlet of the flow meter 8. It also includes a speed control switch 10 connected to the inlet of each flow meter 8.

[0036] The water-holding device includes a placement box 11 mounted on a base plate 1. A spring-loaded ring can 12 is slidably inserted into the placement box 11, and two corresponding connectors 13 are fixedly connected to the upper surface of the spring-loaded ring can 12. By placing the spring-loaded ring can 12 inside the placement box 11, the spring-loaded ring can 12 becomes more stable.

[0037] The water supply mechanism includes multiple air pumps 14 mounted on the base plate 1. The output end of the air pump 14 is connected to the spring ring tank 13. Drain pipes 15, which are respectively connected to both ends of the speed control switch 10, are inserted into the two connectors 13.

[0038] The test frame consists of support rods 16 arranged in a rectangular array and fixedly connected to the upper surface of the base plate 1. The fixing plate 7 is located between the opposite sides of the two support rods 16.

[0039] Each cavity 6 is equipped with a heat insulation sheet 17, which forms a test area between itself and the support plate 4. The heat insulation sheet 17 is made of foam and simply fits into the cavity 6. A through hole 18 is provided in the center of each heat insulation sheet 17. By providing heat insulation sheets 17 in each cavity 6 and providing through holes 18 in the center of each heat insulation sheet 17, the test area can be connected to the outside environment to maintain a balance of temperature and humidity as much as possible, while preventing rapid evaporation of moisture and rapid loss of heat, which would affect the test results.

[0040] Specifically, the method of using this utility model is as follows: The tester can adjust the position of the insert plate 29 on the vertical plate 27 according to their height, then place the support frame on the insert plate 29, then place the experimental table on the support frame, place the fabric on the support plate 4, start the air pump, and have its output end connected to the drain pipe 22 via the connector 13 to inject gas into the inside of the spring ring tank 12. The speed control switch 8 is then turned to allow pure water to enter the flow meter 8, and then immerse the fabric through the water inlet pipe 9, the orifice 3, and the water inlet hole 5. The heat generated after the fabric absorbs moisture is measured using the temperature measuring strip 20. The temperature measuring strip can be electrically connected to an external display system (e.g., a computer) for easy observation by the tester.

[0041] Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples mentioned above.
