Description

Technical Field

[0001] The invention belongs to the technical field of wear resistance testing, and in particular relates to a device and a method for testing the wear resistance of clothing fabrics. Background Art

[0002] The clothing fabric wear resistance test device is a device used to evaluate the durability and wear resistance of fabrics or fabrics under friction conditions. For underwear fabrics, since they are used closer to the skin, accurate wear resistance tests are usually required. By simulating the friction of fabrics in daily use, the wear, pilling, shedding or damage of fabrics after multiple frictions can be detected.

[0003] In the prior art, the wear resistance testing device for clothing fabrics usually uses a friction disk for relative friction during the test process, and records the time of fuzzing and shedding, and evaluates the wear resistance in combination with the friction frequency. Especially for fabrics for making underwear, higher requirements for comfort and more significant wear resistance are often required. During the production process, accurate wear resistance tests are performed to evaluate the fabric performance. However, in the actual wear resistance test process, when a dynamic friction disk is used to perform relative friction with the fabric, a simple unidirectional reciprocating motion is often used. The relative motion direction in the actual wear resistance test process is single, and the test accuracy is limited. For the comprehensive wear resistance of the fabric, the true performance of the fabric cannot be accurately tested in a single friction direction, and the test effect is poor.

At the same time, when the outer circumference is pressed synchronously, the top of the fabric is completely unfolded and flattened, and squeezed and tensioned. Then the composite control component 6 is started, and the air supply group is started at the same time. Component 9, the motor 61 drives the connecting shaft 62 to rotate, and makes the distribution head 63 rotate in the distribution cover 64, and the air supply component 9 inputs the pressurized air into the connecting shaft 62 in the composite control component 6, and blows it out through the connecting cavity 67 and the connecting port 66, and when the raised head 65 rotates to the left, the pressurized air is input into the connecting pipe 57 of the friction test part 5, and is introduced into the corresponding sleeve frame 56, and pushes the corresponding movable rod 51 to move horizontally, so that the sleeve plate 52, the connecting rod 53 and the friction plate 54 move horizontally synchronously, move along the top of the fabric frictionally, and compress the spring 1 55, when the distribution head 63 rotates to the right , pressurized air is input into the right sleeve frame 56, so that the movable rod 51 moves horizontally in the opposite direction, and so on and so forth, completing the reciprocating friction of the top of the fabric; with the rotation of the composite control component 6, the cam 68 is synchronously driven to rotate, and the push rods 83 on both sides are intermittently pushed, so that the push rods 83 in the hydraulic assembly 8 compress the hydraulic oil in the corresponding hydraulic cylinder 81 along the direction of movement, and while compressing the spring 84, the hydraulic oil is further compressed into the side cylinder 85 through the curved tube 86, and the corresponding sleeve push rod 73 is pushed to move, so that the tooth plate 71 moves horizontally, and the meshing gear 23 is driven to rotate, so that the top of the support column 21 The fabric and the side pressure ring 33 swing synchronously, and as the cam 68 rotates, the push rods 83 on the left and right sides are intermittently pushed to control the reciprocating push assembly 7 to move back and forth, so that the meshing rotating support part 2 is driven to rotate back and forth, and the fabric positioned and tensioned on the top is reciprocated and swung back and forth.
