Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fabric testing equipment, and in particular to a uniform sweating simulation structure for fabric adhesion testing. Background Technology
[0002] When clothes are worn, they become soaked as the body sweats. Some materials even stick to the skin. Therefore, among the many tests required for clothing fabrics is the fabric adhesion test. The specific test method involves stretching the fabric and attaching it to a sweat-simulating board. Stress sensors are placed on the sweat-simulating board, and then the fabric is moved longitudinally and tangentially. The measured data is collected and recorded to calculate the fabric adhesion rate. Existing sweat-simulating boards have simple water-permeable functions and cannot accurately simulate the effect of uniform sweating of the human body, resulting in inconsistent experimental data, which urgently needs improvement. Utility Model Content
[0003] To address the shortcomings of the aforementioned technologies, this utility model provides a uniform sweating simulation structure for fabric adhesion testing, comprising a sweating front plate, a sweating back plate, a sensor mounting block, and several water inlet connectors for connection to a water source. The sweating front plate and the sweating back plate are detachably connected. The sensor mounting block is fixedly mounted on the back of the sweating back plate. The sweating front plate is uniformly provided with several sweating holes, and the sweating back plate is provided with several water inlets. The several water inlet connectors are all connected to the water inlets. The invention is characterized in that: the sweating front plate has an installation cavity, and the installation cavity is provided with a detachable uniform water outlet plate. The shape and size of the uniform water outlet plate match the installation cavity. The uniform water outlet plate is provided with several water storage chambers, and the several water storage chambers are provided with several water outlet holes. The several water inlets are respectively connected to the several water storage chambers.
[0004] By adopting the above technical solution, a sweating simulation structure is set up, including a sweating front plate, a sweating back plate, a sensor mounting block, and several water inlet connectors. A uniform water outlet plate is set inside the sweating front plate, so that during the simulation test, the water used for simulating sweating can be evenly injected into each water storage chamber through the water inlet connectors and water inlets. When the water storage chamber is filled, the water will flow out evenly from several water outlets. In this way, the water flowing out can further seep out evenly from each sweating hole of the sweating front plate, maximizing the reproduction of the effect of human skin sweating and making the experimental results more accurate.
[0005] A further feature of this invention is that a plurality of hydrophilic membranes, the same number as the water storage cavity, are provided in the mounting cavity at a position between the uniform water outlet plate and the sweating front plate, and the plurality of hydrophilic membranes cover the plurality of water outlet holes of the corresponding water storage cavity.
[0006] By adopting the above technical solution, since the installation cavity is provided with a number of hydrophilic membranes in the same quantity as the water storage cavity at the position between the uniform water outlet plate and the sweating front plate, and the hydrophilic membranes cover the water outlet holes of the corresponding water storage cavity, the water seeping out from the water outlet holes first contacts the hydrophilic membrane and wets the entire hydrophilic membrane, and then seeps out evenly from the other end of the hydrophilic membrane, making the water output more uniform.
[0007] A further feature of this invention is that each of the plurality of water storage chambers is provided with a water outlet chamber near the top, and each of the plurality of water outlet holes is provided within the water outlet chamber.
[0008] By adopting the above technical solution, since each of the several water storage chambers is provided with a water outlet chamber near the top, and the several water outlet holes are all set in the water outlet chambers, when the water level in the water storage chamber reaches the position of the water outlet chamber, the speed of water level rise slows down, and the water can flow out from the water outlet hole more slowly, further improving the simulation effect.
[0009] A further feature of this invention is that sealing grooves are provided on both ends of the uniform water outlet plate, and rubber sealing rings are provided in each sealing groove.
[0010] By adopting the above technical solution, since sealing grooves are opened on both ends of the uniform water outlet plate, and rubber sealing rings are provided in the sealing grooves, the internal sealing performance is further improved.
[0011] A further feature of this invention is that the outer edge of the sweating front plate is chamfered.
[0012] By adopting the above technical solution, since the outer edge of the sweating front plate is chamfered, when the fabric is attached to the sweating front plate and subjected to longitudinal and tangential forces, the fabric will not have difficulty moving due to the resistance at the edge of the sweating front plate, thus ensuring the accuracy of the measurement data.

Detailed Implementation
[0017] like Figure 1-3 The diagram illustrates a uniform sweating simulation structure for fabric adhesion testing, comprising a sweating front plate 1, a sweating back plate 2, a sensor mounting block 3, and several water inlet connectors 4 for connection to a water source. The sweating front plate and the sweating back plate are detachably connected. The sensor mounting block is fixedly mounted on the back of the sweating back plate. The sweating front plate is uniformly provided with several sweating holes 5, and the sweating back plate is provided with several water inlets 6. The several water inlet connectors are all connected to the water inlets. The structure is characterized in that: the sweating front plate has an installation cavity 7, and the installation cavity is provided with a detachable uniform water outlet plate 8. The shape and size of the uniform water outlet plate match the installation cavity. The uniform water outlet plate is provided with several water storage chambers 9, and the several water storage chambers are provided with several water outlet holes 10. The several water inlets are respectively connected to the several water storage chambers.
[0018] By setting up a sweating simulation structure including a sweating front plate, a sweating back plate, a sensor mounting block, and several water inlet connectors, and then setting a uniform water outlet plate inside the sweating front plate, the water used for simulated sweating can be evenly injected into each water storage chamber through the water inlet connectors and inlets during the simulation experiment. When the water storage chamber is filled, the water will flow out evenly from several water outlets. In this way, the water flowing out can further seep out evenly from each sweating hole of the sweating front plate, maximizing the reproduction of the effect of human skin sweating and making the experimental results more accurate.
[0019] The mounting cavity is provided with a number of hydrophilic membranes 11, the same number as the water storage cavity, located between the uniform water outlet plate and the sweating front plate. The hydrophilic membranes cover the water outlet holes of the corresponding water storage cavity.
[0020] Because the same number of hydrophilic membranes as the water storage cavity are provided in the mounting cavity at the position between the uniform water outlet plate and the sweating front plate, and the hydrophilic membranes cover the water outlet holes of the corresponding water storage cavity, the water seeping out from the water outlet holes first contacts the hydrophilic membrane and wets the entire hydrophilic membrane, and then seeps out evenly from the other end of the hydrophilic membrane, making the water output more uniform.
[0021] Each of the several water storage chambers is provided with a water outlet chamber 12 located near the top, and each of the several water outlet holes is provided in the water outlet chamber.
[0022] Since each of the several water storage chambers has a water outlet chamber located near the top, and the several water outlet holes are all located in the water outlet chambers, when the water level in the water storage chamber reaches the position of the water outlet chamber, the rate of water level rise slows down, and the water can flow out from the water outlet hole more slowly, further improving the simulation effect.
[0023] Both ends of the uniform water outlet plate are provided with sealing grooves 13, and each sealing groove is provided with a rubber sealing ring 14.
[0024] Since sealing grooves are opened on both ends of the uniform water outlet plate, and rubber sealing rings are provided in the sealing grooves, the internal sealing performance is further improved.
[0025] The outer edge of the sweating front plate is chamfered by 15.
[0026] Because the outer edge of the sweating front plate has a chamfer, when the fabric is attached to the sweating front plate and subjected to longitudinal and tangential forces, the fabric will not have difficulty moving due to the resistance at the edge of the sweating front plate, thus ensuring the accuracy of the measurement data.
