A single test process is time-consuming and the experimental cost is high. Utility Model Content

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0026] like Figure 1 As shown, in one embodiment, a laboratory-used jig for simulating the washability of bonded fabrics includes: a washing component 1 , a testing component 2 , and a temperature control component 3 .

[0027] Among them, the test component 2 and the temperature control component 3 are arranged on one side of the water washing component 1. The water washing component 1 is used to continuously wash the test sample 4 with water, the test component 2 is used to continuously pull the test sample 4, and the temperature control component 3 is used to maintain the cleaning liquid at a constant temperature.

[0028] Please continue reading Figure 1 In this embodiment, the water washing assembly 1 includes a test tank 11 and an impact device 12. The impact device 12 is used to vibrate the cleaning liquid in the test tank 11, use the cleaning liquid to transmit pressure, and continuously impact the fabric interface.

[0029] After the cleaning fluid is introduced into the test tank 11, it is heated, which exerts greater pressure on the fabric bonding interface than washing in water at room temperature. The cleaning fluid ratio and temperature in the test tank 11 can be set according to the test requirements. It should be noted that the cleaning fluid used in this application is a cleaning fluid with a ratio of ethanol / water / surfactant = 15:84:1. When heated to the set temperature (60°C), it is more damaging to the fabric interface than traditional water plus detergent, which can effectively shorten the test cycle.

[0030] Furthermore, the impact device 12 is symmetrically arranged at the bottom of the test slot 11, and includes a first pulse device 121 and a second pulse device 122. During testing, the console parameters can be adjusted according to test requirements, including switching the pulse device and adjusting the pulse energy.

[0031] Specifically, the first pulse device 121 is set at the bottom center of the test tank 11, facing the sample 4 to be tested, and uses pulses to perform continuous longitudinal impact on the interface center of the sample 4 to be tested; the second pulse device 122 is symmetrically set on both sides of the first pulse device 121, and uses standing waves to stabilize the liquid level test rod 21 to reduce the disturbance of the test rod 21.

[0032] Please continue reading Figure 1 In this embodiment, the test assembly 2 includes a test rod 21, a servo motor 22 and a transmission motor 23. The servo motor 22 drives the belt 24 through the transmission motor 23 to drive the test rod 21 to reciprocate, thereby pulling the fabric interface laterally.

[0033] Furthermore, a test rod 21 is symmetrically positioned within the test slot 11 and connected to one end of the test sample 4. The test sample is prepared in a jig using a 180° peel angle and then cured in a constant temperature and humidity chamber for 72 hours before undergoing subsequent aging testing. During the aging test, the cured test sample is secured within the test slot 11 using a jig for subsequent testing.

[0034] The jig includes an adhesive portion 41 and a head portion 42. The adhesive portion 41 is glued to the inside of the test slot 11, and the head portion 42 is peeled off at a set angle (180°) for sample preparation. The length of the head portion 42 when unfolded is half of the adhesive portion 41. After curing at room temperature for a certain period of time, the sample 4 to be tested is connected to the test rod 21 for testing.

[0035] During the test, after the test sample 4 is fixed, since the test sample 4 has a certain elasticity, the test sample 4 will also produce a certain displacement when stretched. Therefore, in the actual sample, the bonding part 41 of the glue is not taut, but has a certain displacement.

[0036] Furthermore, after passing through the test slot 11, the test rod 21 is connected to a belt 24. A sealing ring 13 is provided at the connection between the test rod 21 and the test slot 11 to prevent the cleaning fluid from leaking out of the test slot 11. The servo motor 22 is rotationally connected to the transmission motor 23, which is in turn rotationally connected to the belt 24, which is in transmission connection with the test rod 21. During testing, the servo motor 22 drives the transmission motor 23 to rotate back and forth, which in turn drives the belt 24, which drives the test rod 21 to reciprocate at a constant tension, thereby horizontally stretching the test specimen 4.

[0037] Please continue reading Figure 1 In this embodiment, the temperature control component 3 includes a mold temperature controller 31 , which is used to control the temperature of the cleaning liquid in the test tank 11 .

[0038] Specifically, the middle of one side of the test tank 11 is connected to the mold temperature controller 31 through a pipe, and the bottom of the other side of the test tank 11 is connected to the mold temperature controller 31 through a pipe. The circulation of the insulation medium is realized through the pipe, and the temperature of the cleaning liquid in the test tank 11 is accurately adjusted, thereby ensuring the stability of the test conditions.

[0039] Through the above technical solution, the sample needs to be prepared as a standard sample in the fixture according to the 180° peeling method, and then it needs to be placed in a constant temperature and humidity chamber for 72 hours. After it is completely cured, it is fixed in the test tank 11 for aging test. After the cleaning liquid configured in the test tank 11 is heated by the mold temperature controller 31, the cleaning liquid is vibrated by the impact device 12, and the longitudinal fluctuation of the cleaning liquid is used to continuously impact the fabric interface. The servo motor 22 drives the belt 24 through the transmission motor 23 to control the reciprocating movement of the test rod 21 with a constant tension, pulling the fabric interface horizontally, causing great damage to the fabric interface, effectively shortening the test cycle and improving the test efficiency.

[0040] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
