Description
Technical Field
[0001] The present application relates to the technical field of textile fabric testing, and in particular to a textile fabric elasticity testing device and a testing method. Background Art
[0002] Textile fabrics are materials used to make clothing. Textile fabrics with good toughness are not easily torn. As clothing materials, textile fabrics can not only interpret the style of clothing, but also show the characteristics of clothing. By testing the elasticity of textile fabrics, we can simulate the tensile force that the fabric bears when it is stretched to plastic deformation, and obtain the tensile strength of the fabric.
[0003] The Chinese patent with publication number CN 112577831 A and name “A Textile Fabric Tensile Strength Testing Equipment” can clamp and pull the textile fabric through the cooperation of a driving mechanism, a clamping mechanism and a non-return mechanism, thereby achieving the tensile strength test effect. It does not require manual clamping, which improves the test efficiency. The textile fabric can be quickly flattened through the feeding mechanism, and there is no need to manually spread and flatten the textile fabric, which can ensure the test effect of the textile fabric. The indicating component can achieve the position of the first rack movement without the need for manual measuring tools, making the test result more intuitive.

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0035] See also Figure 1-11 A textile fabric elasticity testing device provided in an embodiment of the present invention comprises a base frame 1; and a test box 2, which is installed at the upper end of the base frame 1, and the test box 2 is a rectangular hollow structure; two test components 3, which are symmetrically installed on the left and right sides of the test box 2, and the test components 3 are configured to clamp and fix the textile fabric and drive the textile fabric to perform elasticity testing; a detection component 4, which is installed in the middle of the test box 2, and the detection component 4 is configured to perform deformation detection on the textile fabric after the test is completed.
[0036] In the above technical solution, firstly, a textile fabric of appropriate size is cut, and the ends of the textile fabric are installed between two test components 3, and the textile fabric is ensured to be in a taut state. Then, the test component 3 performs an elastic tensile test on the textile fabric through horizontal reciprocating motion. The test component 3 drives the textile fabric after the test to move downward and contact with the detection component 4. The detection component 4 is used to perform deformation detection on the textile fabric after the test.
[0037] It should be noted that during the elasticity test of the textile fabric, the reciprocating motion stroke of the test component 3 gradually increases, and then the function of tensile testing the textile fabric can be realized by setting different pulling forces. By detecting the deformation of the textile fabric, the maximum pulling force that the textile fabric can withstand can be accurately detected.
[0038] See also Figure 4-5 As shown, as the preferred technical solution of this embodiment, the test assembly 3 includes a U-shaped frame 31, a support platform 32, a lifting plate 33, an electric slider 34, an electric slide rail 35, a connecting frame 36 and a clamp 37, the U-shaped frame 31 is respectively installed on the left and right sides of the inside of the test box 2, the support platform 32 is installed at the lower end of the U-shaped frame 31, the electric slider 34 is symmetrically installed on the inner wall of the U-shaped frame 31, the lifting plate 33 is installed between the electric sliders 34, the electric slide rails 35 are respectively installed on the front and rear sides of the upper end of the lifting plate 33, the connecting frame 36 is installed between the electric slide rails 35, and the clamps 37 are evenly installed on the connecting frame 36.
[0039] In the above technical solution, the cut textile fabric is loaded between two relatively arranged clamps 37, and then the electric slide rail 35 drives the clamps 37 to move outward through the connecting frame 36, so that the two clamps 37 can pull the textile fabric outward synchronously. When the textile fabric is stretched back and forth to a certain extent, the clamps 37 are restored, and the electric slider 34 drives the textile fabric to move downward and contact the surface of the detection component 4. The detection component 4 can then detect deformation, rupture, tearing and other phenomena on the surface of the textile fabric, which is convenient for accurate testing of the textile fabric.
[0040] It should be noted that during the testing process of textile fabrics, the stretching degree of the textile fabrics is gradually increased, that is, the testing is carried out after the textile fabrics are stretched, and then the testing is carried out again after the stretching amplitude is increased, until the textile fabrics are deformed, ruptured, and torn, etc., and finally the stretching amplitude, deformation amount, rupture and tear number of the textile fabrics are recorded to facilitate accurate testing of the textile fabrics.
[0041] Continue reading Figure 4-5As shown, as a preferred technical solution of this embodiment, the textile fabric is installed between two clamping members 37 arranged opposite to each other, and the clamping members 37 are configured to clamp the ends of the textile fabric and keep the textile fabric in a taut state.
[0042] In the above technical solution, when the cut textile fabric is installed between the two clamps 37, the textile fabric is in a taut state. After the textile fabric undergoes multiple elastic stretching tests, even if the length of the textile fabric changes, the two clamps 37 will still drive the textile fabric to be in a taut state, which is beneficial for subsequent testing of the textile fabric.
[0043] Continue reading Figure 6-7 As shown, as the preferred technical solution of this embodiment, the clamping member 37 includes an outer frame 371, an inner frame 372, a sliding frame 373, a guide groove 374, a guide rod 375 and a telescopic spring 376. The outer frame 371 is installed on the upper end of the connecting frame 36. The cross-section of the outer frame 371 is a U-shaped structure. The inner frame 372 is installed inside the outer frame 371. The inner frame 372 is a U-shaped structure. The sliding frame 373 is slidably arranged inside the inner frame 372. The cross-section of the sliding frame 373 is a T-shaped structure. The inner frame 372 is evenly provided with guide grooves 374. A guide rod 375 is slidably arranged in the guide groove 374. The guide rod 375 is installed on the sliding frame 373. The guide rod 375 is provided with a telescopic spring 376.
[0044] In the above technical solution, the inner frame 372 is detachably arranged. When the textile fabric is installed, the inner frame 372 needs to be disassembled and then the end of the textile fabric needs to be installed inside the sliding frame 373. When the inner frame 372 is installed on the outer frame 371, the sliding frame 373 slides inward and the telescopic spring 376 is in a taut state. When the inner frame 372 is completely installed, the guide rod 375 moves to the innermost side of the guide groove 374 to ensure that the textile fabric is in a taut state.
[0045] It should be noted that after the elastic pulling test of the textile fabric, the textile fabric is deformed when it is pulled, resulting in a change in the length of the textile fabric. At this time, since the telescopic spring 376 is in a tensioned state, the telescopic spring 376 drives the sliding frame 373 to move outward, and then the textile fabric can be tightened again, so that the textile fabric can accurately contact the surface of the detection component 4, thereby ensuring the accuracy of subsequent detection of the textile fabric.
[0046] See also Figure 7 As shown, as a preferred technical solution of this embodiment, a rectangular groove for clamping textile fabrics is provided in the middle of the sliding frame 373, and a pressure plate 377 for pressing the textile fabrics is provided in the rectangular groove. The inner side of the pressure plate 377 is a flexible structure, and the pressure plate 377 is mounted on the sliding frame 373 by screws.
[0047] In the above technical solution, when the textile fabric is installed inside the sliding frame 373, the pressure plate 377 is driven to move inward by the screws, so that the pressure plate 377 can accurately clamp and fix the textile fabric. At the same time, in order to prevent the textile fabric from breaking due to stress concentration at the clamping mouth, in this embodiment, the inner side of the pressure plate 377 is set as a flexible structure. The flexible structure can effectively play a buffering role, which is convenient for the subsequent tensile test of the textile fabric.
[0048] It should be noted that, in order to improve the tensile test effect of the textile fabric, the end of the textile fabric can be set to a trapezoidal structure, that is, the two ends of the textile fabric are trapezoidal structures, and the textile fabric with the trapezoidal structure is completely fixed by the pressing plate 377, thereby effectively preventing the textile fabric from breaking at the clamp during testing.
[0049] Continue reading Figure 7 As shown, as a preferred technical solution of this embodiment, a distance meter is installed inside the guide groove 374, and the distance meter is configured to record the increased length of the textile fabric relative to the initial position after the elasticity test is completed.
[0050] In the above technical solution, when the textile fabric is subjected to a stretch test, the length of the textile fabric will change due to the deformation of the textile fabric when it is stretched. In order to accurately record the deformation of the textile fabric in the length direction, a rangefinder is provided in this embodiment. The rangefinder is a prior art. The rangefinder can accurately measure the distance between the innermost sides of the guide groove 374 at the end of the guide rod 375, and thus can accurately measure the deformation of the textile fabric after each stretching and the maximum deformation.
[0051] See also Figure 8-10 As shown, as the preferred technical solution of this embodiment, the detection component 4 includes a mounting frame 41, a rectangular frame 42, a detection unit 43 and a detection diaphragm 44. The mounting frame 41 is installed in the middle of the test box 2, and mounting grooves are evenly arranged on the mounting frame 41. The rectangular frame 42 is installed in the mounting groove. The middle part of the rectangular frame 42 is a hollow structure. The detection units 43 are evenly installed on the upper end of the rectangular frame 42 along its length direction, and the detection diaphragm 44 is installed at the lower end of the rectangular frame 42. The lower end of the detection unit 43 is tightly attached to the detection diaphragm 44.
[0052] In the above technical solution, the detection diaphragm 44 is a piezoelectric film, which can accurately sense pressure changes. When the stretched textile fabric moves downward and contacts the detection unit 43, the deformation, rupture and tearing of the textile fabric can be detected through the inductive contact between the downward movement of the detection unit 43 and the detection diaphragm 44.
[0053] See also Fig.10 As shown, as a preferred technical solution of this embodiment, the detection unit 43 includes a locking frame 431, a guide sleeve 432, a detection probe 433 and a connecting spring 434. The locking frame 431 is installed on the rectangular frame 42 by screws, and through holes are evenly arranged on the locking frame 431. The guide sleeve 432 is installed in the through hole. The detection probe 433 is slidably arranged in the guide sleeve 432. The detection probe 433 is in a T-shaped structure, and a connecting spring 434 is installed between the middle part of the detection probe 433 and the guide sleeve 432.
[0054] In the above technical scheme, the detection probe 433 is only in close contact with the surface of the detection diaphragm 44 in the initial state. When the stretched textile fabric moves downward, the textile fabric contacts the upper end of the detection probe 433, and the detection probe 433 is squeezed and moves downward. The detection diaphragm 44 is squeezed by the mutual cooperation between the multiple detection probes 433. The contact between the detection probe 433 and the detection diaphragm 44 can generate sensing points, so that the shape of the textile fabric can be depicted on the detection diaphragm 44 between the multiple pressure sensing points. By comparing the shape after detection with the initial shape, the function of detecting defects such as deformation, rupture, and tearing of the textile fabric can be realized.
[0055] It should be noted that if Fig.11 As shown, if the shape of the textile fabric depicted is the same as the initial shape, it means that the textile fabric has not been deformed and the textile fabric is normal fabric 101; if the shape of the textile fabric depicted is different from the initial shape, it means that the textile fabric has not been deformed and the textile fabric is deformed fabric 102; if there are unsqueezed sensing points inside the shape of the textile fabric, it means that the detection probe 433 is not squeezed, indicating that a rupture 103 appears on the textile fabric after the tensile test; if the edge of the shape of the textile fabric depicted is incomplete, it means that a tear 104 appears on the edge of the textile fabric after the tensile test.
[0056] See also Fig.10 As shown, as a preferred technical solution of this embodiment, the detection probe 433 is a lightweight rod, and a flexible pressure head 435 with a conical structure is provided at the upper end of the detection probe 433. The lower end of the detection probe 433 is tightly attached to the surface of the detection diaphragm 44, and the detection diaphragm 44 is configured to monitor the downward pressure between the detection probe 433 and the detection diaphragm 44.
[0057] In the above technical solution, the flexible pressure head 435 can accurately contact the textile fabric to avoid damage to the textile fabric, and at the same time, it is convenient for the textile fabric to squeeze the detection probe 433, which is beneficial to the detection of the stretched textile fabric.
[0058] In addition, the present invention also provides a testing method for a textile fabric elasticity testing device, and the testing method for the textile fabric elasticity testing device specifically comprises the following steps:
[0059] S1. Installation of textile fabric ends: firstly, cut a textile fabric of appropriate size, install the ends of the textile fabric between two test components 3, and ensure that the textile fabric is in a taut state;
[0060] S2. Lengthwise tensile test of textile fabric: the test component 3 performs elasticity test on the textile fabric by reciprocating motion in the horizontal direction. During the elasticity test of the textile fabric, the reciprocating motion stroke of the test component 3 gradually increases;
[0061] S3, textile fabric deformation detection: the testing component 3 drives the tested textile fabric to move downward and contact with the detection component 4. The detection component 4 is used to perform deformation detection on the tested textile fabric.
[0062] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
