Description

TECHNICAL FIELD

[0001] The utility model relates to textile performance testing device field, more specifically, it relates to a kind of clothing pilling performance detection clamping tool based on Martin Dale method. BACKGROUND

[0002] Martin Dale fuzz and pilling test method is a kind of test method for evaluating the performance of textile in actual use against fuzzing and pilling. The principle of this method is to rub a circular fabric sample under certain pressure with the trajectory of Lissajous figure with itself or other fabrics. During rubbing, the sample can rotate freely around the central axis perpendicular to the sample plane. After a certain period of rubbing, the wear, fuzzing or pilling of the sample is evaluated by visual description. This performance test requires the use of Martin Dale abrasion tester.

[0003] The existing Martin Dale abrasion tester, for example, YG(B)401T type Martin Dale abrasion tester, its test method and principle are: cutting the fabric to be tested into a circular sample, placing the sample on the upper part of the grinding table, the outer ring surface of the grinding table is provided with external threads, using the external threads to cooperate with the clamping ring with internal threads to clamp the fabric to be tested on the grinding table, then clamping the abrasive in the abrasive clamp specially for clamping abrasive, and then driving the abrasive to run with fixed trajectory by the driving motor in the abrasion tester to perform pilling experiment on the fabric to be tested. When loading the fabric to be ground or the abrasive, the surface needs to be kept flat, so other flat weights need to be used to press on the surface of the fabric to be tested, and then force is fixed to ensure the flatness of the surface of the fabric to be tested. This clamping method requires certain skills and attention to ensure the flatness and wrinkle-free of the sample, which requires the tester to carefully follow the operation steps to avoid affecting the accuracy of the test results, and the operation is relatively cumbersome, so a new scheme is needed to ensure the flatness of the surface of the fabric to be tested while simplifying the operation of the tester. SUMMARY

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a clothing pilling performance detection clamping tool based on Martin Dale method, which has the effect of smoothing the surface of the fabric to be tested when fixing the fabric to be tested.

[0015] In summary, the utility model has the following beneficial effects:

[0016] (1) The present invention opens a square groove in the fabric table and uses the design of the first and second weight rods being connected to each other by a connector. When the fabric to be tested is placed in the square groove, the minimum connection angle between the second weight rod and the first weight rod can be set to 0 degrees to ensure that the second weight rod can fit against the edge of the square groove and be placed on the outermost side of the fabric to be tested.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0024] Example: A clamping tool for testing the pilling performance of clothing based on the Martindale method, such as... Figure 1 , Figure 2As shown, the device includes a worktable 1, a drive assembly located within the worktable 1, and a mounting plate 2 driven by the drive assembly and located above the worktable 1. The worktable 1 is provided with a fabric clamp 4 for holding the fabric to be tested, and the mounting plate 2 is provided with an abrasive assembly 3. The fabric clamp 4 includes a fabric table 41 and a smoothing assembly 42 rotatably connected to the fabric table 41. The fabric table 41 has a square groove 411 for placing the fabric to be tested. The smoothing assembly 42 includes a first weight rod 421 rotatably connected to the fabric table 41 and a second weight rod 422 rotatably connected to the first weight rod 421. The first weight rod 421 is used to connect to the fabric table 41, and the second weight rod 422 is used both to fix to the fabric table 41 and to smooth the surface of the fabric to be tested by moving it from one side of the fabric table 41 to the other side when the fabric to be tested is fixed on the fabric table 41.

[0025] Specifically, such as Figure 1 , Figure 2 In the embodiment of this utility model shown, by setting a smoothing component 42 consisting of a first weight bar 421 and a second weight bar 422, when the fabric to be tested is fixed in the square groove 411 in the fabric platform 41, the minimum connection angle between the second weight bar 422 and the first weight bar 421 can be rotated to 0 degrees, so that the second weight bar 422 can be placed on the outermost side of the fabric to be tested. Then, the connection angle is gradually increased, and the second weight bar 422 slides against the surface of the fabric to be tested to the other end of the square groove 411, ensuring that the second weight bar 422 can glide across the entire surface of the fabric to be tested. Thus, the smoothing work of the surface of the fabric to be tested is completed during the fixing process, avoiding errors during testing and increasing the accuracy of the test. The specific testing process refers to the Martindale abrasion tester in the prior art. When the equipment is started, the drive component drives the mounting plate 2 to move along a fixed trajectory, and drives the abrasive component 3 to move along a corresponding trajectory while rubbing the surface of the fabric to be tested. The pilling performance of the fabric to be tested is judged by judging the pilling situation in the fabric to be tested after friction.

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, a rotating groove is provided on one side of the fabric table 41. A rotating rod corresponding to the rotating groove is fixedly connected to the rod end of the first weight rod 421 near the rotating groove. The first weight rod 421 is rotatably connected to the fabric table 41 through the cooperation of the rotating groove and the rotating rod. A connecting groove is provided on the end face of the first weight rod 421 and the second weight rod 422 opposite to each other. A connecting member 44 is provided in the connecting groove. The two ends of the connecting member 44 are rotatably connected to the first weight rod 421 and the second weight rod 422 respectively.

[0027] Specifically, such as Figures 1-3In the embodiment of this utility model shown, the design of the connector 44 makes the minimum connection angle between the first weight bar 421 and the second weight bar 422 0 degrees, so that at the beginning of the smoothing process, the second weight bar 422 fits the side of the fabric to be tested to the greatest extent, smoothing the surface of the fabric to be tested to the greatest extent, and further ensuring the accuracy of the test.

[0028] like Figure 1 , Figure 2 As shown, an arc-shaped fitting groove is provided on the side of the fabric platform 41 away from the rotating groove. The end of the second counterweight rod 422 away from the first counterweight rod 421 is rotatably connected to a fitting rod 4221 corresponding to the fitting groove. The fitting rod 4221 is made of spring steel. The second counterweight rod 422 is fitted into the fitting groove and fixed to the fabric platform 41 through the fitting rod 4221.

[0029] Specifically, such as Figure 1 , Figure 2 In the embodiment of this utility model shown, the design of rotating connection between the fitting rod 4221 and the second pressure rod 422 is intended to facilitate the adjustment of the angle of the fitting rod during the smoothing process, ensuring that the second pressure rod 422 always flattens the fabric to be tested with its straight edge without being affected by the fitting rod 4221. Furthermore, the fitting rod 4221, made of spring steel, facilitates the fit between it and the fitting groove.

[0030] like Figure 1 , Figure 2 As shown, when the fitting rod 4221 is placed in the fitting groove, the connection angle between the first weight rod 421 and the second weight rod 422 is 180°. This provides the furthest distance between the first weight rod 421 and the second weight rod 422, ensuring that the pressure applied to the fabric by the first weight rod 421 and the second weight rod 422 is uniform, reducing pilling detection errors and improving experimental accuracy. When the fitting rod 4221 is placed in the fitting groove, there is a gap between the first weight rod 421 and the second weight rod 422 and the bottom of the square groove 411.

[0031] Specifically, such as Figure 1 , Figure 2 In the embodiment of this utility model shown, the spacing design can ensure that the fabric under test is subjected to reasonable pressure from the first pressure bar 421 and the second pressure bar 422. At the same time, the pressure on the fabric under test can be adjusted by placing pads such as wool felt or cotton cloth at the bottom of the fabric under test, thereby further improving the stability of the fabric under test during the testing process and obtaining more accurate experimental data.

[0032] like Figure 1 , Figure 2As shown, both the first counterweight bar 421 and the second counterweight bar 422 are welded and fixed with an arc-shaped bar 43 forming a circle. The arc-shaped bar 43 is designed so that the present invention can conform to the motion trajectory of the Lissajous curve during the testing of the fabric to be tested. This trajectory is a standard feature of the Martindale abrasion test.

[0033] Working principle: Before testing, the fabric to be tested and the pad are cut to correspond to the shape of the square groove 411. Then, the pad is placed in the square groove 411 of the fabric platform 41, and the fabric to be tested is laid on the top layer. The second pressure bar 422 is rotated to fit the edge of the square groove 411. Then, force is applied to the second pressure bar 422 in a way that fits the surface of the fabric to be tested, so that the connection angle between it and the first pressure bar 421 gradually increases until it reaches 180 degrees. Then, the fitting bar 4221 is fitted into the fitting groove opened on the other side of the fabric platform 41 to complete the fixation. At this time, the surface of the fabric to be tested is flat and the pressure is uniform. In addition, the design of the arc-shaped bar 43 can also meet the standard feature of the motion trajectory conforming to the Lissajous curve during the testing process. This utility model ensures the flatness of the surface of the fabric to be tested, while also simplifying the fixing steps of the fabric to be tested.

[0034] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
