Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile processing technology, specifically to a device for testing the air permeability of blended textiles. Background Technology
[0002] Within the professional fields of materials science and textile engineering, textiles are a concept with a clear definition and rich connotations. Essentially, textiles refer to flexible sheet or thread-like materials made from natural or chemical fibers through specific textile processing techniques. Natural fibers here encompass plant fibers (such as cotton and hemp), animal fibers (such as wool and silk), and mineral fibers (such as asbestos); chemical fibers are fibers prepared by artificial synthesis or semi-synthetic methods, such as polyester and nylon fibers.
[0003] The existing patent announcement number CN210427274U discloses a textile testing device, including a first housing, a steam generator, an end cap, a fixing base, a clamp for fixing the fabric to be tested, a booster pump, a first detection mechanism, and a second detection mechanism. A detection chamber is formed on the front side of the first housing. The end cap is movably mounted on the top of the detection chamber via a connecting rod, and the fixing base is mounted on the bottom of the detection chamber opposite to the end cap. The steam generator is installed at the bottom of the first housing and communicates with the second detection chamber via an air inlet pipe, allowing steam to fill the second detection chamber and then permeate the fabric to be tested. The first detection mechanism is mounted on the top of the first detection chamber, and the second detection mechanism is installed inside the second detection chamber. The booster pump is connected to the second detection chamber via a pressure pipe. This invention can detect the air permeability of fabrics by detecting humidity changes and is easy to operate.
[0004] While the above-mentioned technical solution detects fabric breathability by monitoring humidity changes, the fabric surface, when not stretched flat, exhibits wrinkles, undulations, and other unevenness. This prevents airflow from passing evenly across all areas. For example, in areas with denser wrinkles, the airflow channel narrows, resistance increases, and airflow speed decreases; conversely, in flatter areas, airflow is smoother. This uneven airflow distribution causes inaccuracies in the breathability data recorded by the testing device, failing to accurately reflect the overall breathability performance of the fabric. Therefore, we provide a device for testing the breathability of blended textiles. Utility Model Content

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] This utility model provides a technical solution: such as Figures 1-4As shown, in this embodiment, a device for testing the air permeability of blended textiles includes a processing table 11. Screws 12 are installed in slots on both sides of the processing table 11. A handle 18 is installed at one end of each screw 12 facing each other. A bearing 13 is installed at one end of each screw 12 opposite to the handle 18. One end of each screw 12 is fixedly connected to the handle 18, and the end of the screw 12 away from the handle 18 is fixedly connected to the inner wall of the bearing 13. Threaded plates 14 are installed on the outside of each screw 12. One side of the bearing 13 is fixedly connected to the inner wall of the slot on the processing table 11 away from the handle 18. Threaded grooves on the threaded plates 14 are threadedly connected to the outside of the screw 12. Feeding plates 15 are installed on the top of each threaded plate 14. Threaded grooves on the top of each feeding plate 15 are provided with… The adjustment screws 16 are equipped with pressure plates 17 at their bottoms. The top of the threaded plate 14 is fixedly connected to the feed plate 15. The threaded groove on the top of the feed plate 15 is connected to the external thread of the adjustment screws 16. The bottom of the adjustment screws 16 is rotatably connected to the top of the pressure plate 17. The processing table 11 has slots 19 at both ends. The top of the processing table 11 is equipped with a detection base 110. The top of the detection base 110 has a docking groove 111. The inside of the detection base 110 is equipped with a flow sensor 112. The bottom of the detection base 110 is fixedly connected to the top of the processing table 11. A display 31 is installed on one side of the top of the processing table 11. The display 31 is electrically connected to the flow sensor 112. The top of the processing table 11 is equipped with a detection mechanism 2.
[0025] In this embodiment, when the device is used to test the air permeability of textile fabric, the part of the fabric to be tested is first placed on the testing base 110, and both ends of the fabric are passed through the slots opened on the two feeding plates 15. The ends of the fabric that have passed through are smoothed and placed in the empty slot 19 to avoid wrinkles that would affect market sales. By rotating the two adjusting screws 16, the height of the pressure plates 17 connected to each other can be adjusted. When the two pressure plates 17 are adjusted to the appropriate height, the fabric placed in the feeding plates 15 at both ends can be pressed. Then, the two handles 18 are rotated to drive the screws 12 connected to each other to rotate, thereby adjusting the position of the feeding plates 15 on the processing table 11. When the two feeding plates 15 move towards each other on the processing table 11, the fabric in the middle can be pulled. Therefore, wrinkles, undulations and other uneven conditions of the fabric on the testing base 110 can be avoided, ensuring that the air permeability data will be relatively accurate in the subsequent air permeability test.
[0026] like Figures 1-4As shown, the detection mechanism 2 includes a telescopic cylinder 21. The bottom of the telescopic cylinder 21 is fixedly connected to the top support of the processing table 11. The output end of the bottom of the telescopic cylinder 21 is fixedly connected to the top of the connecting frame 22. The bottom of the connecting frame 22 is fixedly connected to a mounting plate 23. An air compressor 24 is fixedly installed on the top of the mounting plate 23. An annular washer 25 is fixedly connected to the bottom of the mounting plate 23. The outer part of the annular washer 25 is mated in the mating groove 111.
[0027] In this embodiment, after the fabric is fixed and the tension is adjusted, the telescopic cylinder 21 can be activated to drive the connecting frame 22, the mounting plate 23, and the air compressor 24 to descend. Therefore, the annular washer 25 at the bottom of the mounting plate 23 will contact the fabric and press the contacted fabric into the docking groove 111. It is worth mentioning that when the fabric in contact with the annular washer 25 is pressed into the docking groove 111, the tension may be too high. In order to avoid the fabric from tearing, the distance between the feeding plate 15 and the detection base 110 can be finely adjusted. Therefore, after ensuring that the tension of the fabric is adjusted correctly, the air compressor 24 is activated to perform air permeability testing on the fabric in the detection base 110. The air pressure passing through the fabric will be transmitted to the flow sensor 112 and read and recorded by the display 31.
[0028] This utility model provides a device for testing the air permeability of blended textiles, the specific working principle of which is as follows:
[0029] When testing fabric using a textile air permeability testing device, first, place the portion of fabric to be tested on the testing base 110, allowing both ends of the fabric to pass through the slots on the two feed plates 15. Then, rotate the two adjusting screws 16 to adjust the height of the connected pressure plates 17. Once the two pressure plates 17 are adjusted to the appropriate height, they will press the ends of the fabric within the feed plates 15 tightly. Next, rotate the two handles 18 to rotate the connected lead screw 12, thereby adjusting the position of the feed plates 15 on the processing table 11. When the two feed plates 15 move towards each other, they can pull the fabric in the middle, preventing the testing base 110 from being stretched. If the fabric on plate 10 is uneven, after the fabric is fixed and the tension is adjusted, start the telescopic cylinder 21. It will drive the connecting frame 22, the mounting plate 23 and the air compressor 24 to descend, so that the annular washer 25 at the bottom of the mounting plate 23 contacts the fabric and presses the fabric into the docking groove 111. However, it should be noted that when the annular washer 25 presses the fabric into the docking groove 111, the tension may be too high. In order to avoid tearing of the fabric, the distance between the feeding plate 15 and the detection base 110 needs to be finely adjusted. After the fabric tension is adjusted correctly, the air compressor 24 can be started to perform an air permeability test on the fabric in the detection base 110.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
