Description
Technical Field
[0001] This invention relates to the field of fabric abrasion resistance testing technology, specifically a system for testing the abrasion resistance of knitted denim fabric. Background Technology
[0002] Knitted denim fabric is a type of denim fabric made using a knitting process. Compared to traditional woven denim, it has better elasticity and softness. This fabric is produced on a circular knitting machine using bundled dyed indigo denim yarn, creating a faded effect. Abrasion resistance is one of the important performance characteristics of knitted denim fabric. The abrasion resistance of knitted denim fabric is mainly tested by simulating friction conditions to assess the degree of fabric wear. Test items include abrasion resistance testing and color fastness testing, specifically color fastness to rubbing.
[0003] Currently, the abrasion resistance testing equipment for knitted denim fabrics uses a single abrasion plate station, which results in a lack of control in a single abrasion resistance test. This necessitates multiple batches of abrasion resistance testing, but it is difficult to ensure that the same parameters remain constant across multiple control groups of fabrics. For example, when multiple abrasion resistance tests are conducted on fabrics with different friction forces at the same speed under the same temperature and humidity, the probability of error in the test results is high, making the abrasion resistance testing of knitted denim fabrics very difficult.

The base 1 inside the detection chamber 2 is equipped with a detection platform 10. The bottom of the limiting seat 3 is equipped with a fixing mechanism. The top of the detection platform 10 is equipped with the fabric to be tested through the fixing mechanism, realizing a multi-station design for abrasion resistance testing of knitted denim fabric. The multi-station synchronous testing has a reference. The temperature and humidity inside the detection chamber 2 are controllable, which can meet the abrasion resistance testing of fabrics under different temperature and humidity conditions. The rotating table 4 has good limiting rotation stability. The detection platform 10 cooperates with the electric telescopic rod 15 and the ring-shaped clamping plate 151 to have the function of fixing the fabric abrasion resistance testing. The height of multiple grinding plates is adjustable, which can adapt to the adjustable control of friction of fabrics of different thicknesses and multiple sets of abrasion resistance reference tests.
[0021] Specifically, the installation mechanism 7 includes a first threaded rod 71, a handwheel 72, and a first guide rod 73. The top of both the first grinding plate 6 and the second grinding plate 61 is equipped with a first threaded rod 71 via a connecting seat. The first threaded rod 71 is connected to the rotary table 4 through a threaded hole. The top of the first threaded rod 71 is equipped with a handwheel 72. The top of the first grinding plate 6 and the second grinding plate 61 on opposite sides of the first threaded rod 71 is equipped with a first guide rod 73. The first guide rod 73 passes through the rotary table 4 through a guide hole. The rotation of the handwheel 72 drives the first threaded rod 71 to rotate, which can adjust the height of the first grinding plate 6 and the second grinding plate 61. The first guide rod 73 guides and limits the lifting of the first grinding plate 6 and the second grinding plate 61.
[0022] Furthermore, the connecting mechanism 9 includes a second threaded rod 91, a worm gear 92, a worm 93, a knob 94, and a second guide rod 95. The second threaded rod 91 is located in the middle of the top of the third grinding plate 8 via a connecting seat. The top of the rotating platform 4 above the third grinding plate 8 is equipped with a meshing worm gear 92 and a worm 93 via a mounting box. The second threaded rod 91 passes through the rotating platform 4 and is connected to the worm gear 92 through a threaded hole. One end of the worm 93 is connected to the knob 94. The second guide rod 95 is located on the top of the third grinding plate 8 on both sides opposite to the second threaded rod 91. The second guide rod 95 passes through the rotating platform 4 through a guide hole. The knob 94 drives the worm 93 to rotate. The rotation of the worm 93 drives the worm gear 92 to rotate. The second threaded rod 91 on the worm gear 92 drives the third grinding plate 8 to adjust its height. The second guide rod 95 guides the lifting and lowering of the third grinding plate 8.
[0023] Furthermore, the humidification mechanism 5 includes a liquid storage tank 51, a humidification groove 52, a humidification pipe 53, a connector 54, a connecting pipe 55, a humidification pump 56, and a nozzle 57. The second threaded rod 91 has a hollow structure. The liquid storage tank 51 is located on the top of the rotating platform 4 above one side of the third grinding plate 8. The humidification groove 52 is located at the bottom of the third grinding plate 8. The humidification pipe 53 is located inside the third grinding plate 8. The nozzle 57 is located at the bottom of the humidification pipe 53. The outlet of the nozzle 57 is located inside the humidification groove 52. The top of pipe 53 is connected to a fixed pipe. The fixed pipe passes through threaded rod 91 and is connected to connecting pipe 55 via connector 54. The end of connecting pipe 55 away from connector 54 is connected to the output end of humidifying pump 56. The input end of humidifying pump 56 is connected to storage tank 51 via supply pipe. Humidifying pump 56 is located on top of storage tank 51. The friction surfaces at the bottom of grinding plate 6, grinding plate 61, and grinding plate 8 are the same, that is, grinding plate 6 and grinding plate 61 are provided with humidifying grooves 52 as on grinding plate 8. The corresponding groove, the connecting pipe 55 is composed of a straight pipe and a corrugated pipe, and the connecting pipe 55 is equipped with a flow meter to control the humidification of the fabric. When the fabric needs to be tested for abrasion resistance under the same ambient temperature, pressure and speed but different humidity levels, the first grinding plate 6 and the third grinding plate 8 at the bottom of the rotating table 4 are used. That is, the first grinding plate 6 and the third grinding plate 8 are moved down to the top of the test table 10 with the same pressure on the fabric. Under the action of the humidification pump 56, the liquid in the storage tank 51 is pumped through the connecting pipe 55, the fixed pipe and the humidification pipe 53. The liquid inside is atomized by the nozzle 57 into the humidification groove 52 of the third grinding plate 8, and atomized and humidified the fabric surface at the third grinding plate 8 station. The third grinding plate 8 and the first grinding plate 6 station are used to conduct comparative tests on the abrasion resistance of the fabric under different humidity conditions. The nozzle 57 is located on the third grinding plate 8 on the side away from the first grinding plate 6. The nozzle 57 only atomizes and humidifies the fabric surface. The nozzle 57 is far away from the first grinding plate 6 station, so the fabric at the first grinding plate 6 station can remain dry and is not affected by the humidification of the nozzle 57 on the third grinding plate 8.
[0024] Furthermore, pressure sensors 14 are embedded inside grinding plates 6, 61, and 8 through mounting holes. The pressure sensors 14 can detect the pressure (friction force for abrasion resistance testing) of grinding plates 6, 61, and 8 on the fabric. The testing box 2 is equipped with a display screen, and the pressure sensors 14 are connected to the display screen. The data from the pressure sensors 14 on grinding plates 6, 61, and 8 are displayed on the display screen.
[0025] Furthermore, the interior of the testing chamber 2 is equipped with a monitoring probe 16, a heater 17, and a humidifier. The monitoring probe 16 integrates a temperature sensor and a humidity sensor. The temperature sensor and humidity sensor detect the temperature and humidity inside the testing chamber 2. According to the requirements of temperature and humidity for fabric abrasion resistance testing, the temperature and humidity inside the testing chamber 2 can be controlled and adjusted through the heater 17 and the humidifier.
[0026] Furthermore, the fixing mechanism includes an electric telescopic rod 15 and a clamping plate 151. The bottom of the limiting seat 3 is provided with several electric telescopic rods 15, and the bottom of the electric telescopic rods 15 is provided with a clamping plate 151. The clamping plate 151 is arranged in a circular structure. The electric telescopic rods 15 are evenly distributed around the circumference. The bottom of the clamping plate 151 is provided with an anti-slip pad. The fabric to be tested is laid flat on the testing platform 10 at the bottom and top. The electric telescopic rods 15 at the bottom of the limiting seat 3 drive the clamping plate 151 to move down. The clamping plate 151 fixes the fabric on the testing platform 10. The fabric is fixed evenly and firmly, avoiding fabric wrinkles caused by wear-resistant rotation from interfering with the test.
[0027] Furthermore, the limiting seat 3 is provided with a limiting groove on the side near the rotating table 4, and a limiting block 31 is provided inside the limiting groove. A limiting groove 41 is provided on the outer circumference of the rotating table 4. The edge of the rotating table 4 is located inside the limiting groove, and the limiting block 31 is located inside the limiting groove 41. A slider 121 is provided on the top of the rotating plate 12, and a limiting groove is provided on the bottom of the top plate 21. The slider 121 is located inside the limiting groove. The rotation of the rotating plate 12 and the rotating table 4 is limited, and the wear resistance test rotation is stable.
[0028] The method of use in this embodiment is as follows: The fabric to be tested is laid flat on the testing platform 10 at the bottom top. The electric telescopic rod 15 at the bottom of the limiting seat 3 drives the clamping plate 151 to move downwards, fixing the fabric on the testing platform 10. According to the requirements of the fabric testing conditions, the first grinding plate 6, the second grinding plate 61, and the third grinding plate 8 on the rotating table 4 are adjusted. The handwheel 72 and the first threaded rod 71 can adjust the height of the first grinding plate 6 and the second grinding plate 61. The knob 94 drives the worm gear 93 to rotate, which in turn drives the worm wheel 92 to rotate. The second threaded rod 91 on the worm wheel 92 drives the third grinding plate 8 to adjust its height. When different friction forces are required for fabric abrasion resistance testing, the first grinding plate is used. Plate 6 and the second grinding plate 61 are rotated by handwheel 72, which rotates the first threaded rod 71 on the first grinding plate 6 and the second grinding plate 61. The first threaded rod 71 drives the first grinding plate 6 and the second grinding plate 61 to rise and fall on the rotary table 4. The pressure sensor 14 on the first grinding plate 6 and the second grinding plate 61 detects the pressure of the first grinding plate 6 and the second grinding plate 61 on the fabric on the testing table 10. The temperature and humidity sensors on the monitoring probe 16, together with the heater 17 and humidifier inside the testing chamber 2, control the temperature and humidity inside the testing chamber 2. The servo motor 13 on the top plate 21 drives the rotating plate 12 to rotate. The slider 121 slides in the limiting groove on the top plate 21 and rotates through the connecting rod 11. The rotating platform 4 is limited to rotating within the limiting groove of the limiting seat 3, and the limiting block 31 is limited to rotating within the limiting groove 41. The first grinding plate 6 and the second grinding plate 61 at the bottom of the rotating platform 4 are inside the testing chamber 2. Under the same temperature and humidity conditions, multiple sets of fabric abrasion resistance tests are conducted at the same rotation speed with different friction forces. When the fabric needs to be tested for abrasion resistance under the same ambient temperature, pressure, and speed but different humidity conditions, the first grinding plate 6 and the third grinding plate 8 at the bottom of the rotating platform 4 are used. That is, the pressure of the first grinding plate 6 and the third grinding plate 8 on the fabric at the top of the testing platform 10 is the same. Under the action of the humidifying pump 56, the liquid in the storage tank 51 is pumped through the connecting pipe 55, the fixed pipe, and the humidifying pipe 53 through the nozzle. The humidification groove 52 of the No. 3 grinding plate 8 is atomized to humidify the fabric surface at the No. 3 grinding plate 8 station. The No. 3 grinding plate 8 and the No. 1 grinding plate 6 station are used to conduct comparative tests on the abrasion resistance of the fabric under different humidity conditions. This equipment realizes a multi-station design for abrasion resistance testing of knitted denim fabrics. The multi-station synchronous testing has a comparison function. The internal temperature and humidity of the testing chamber 2 are controllable, which can meet the abrasion resistance testing of fabrics under different temperature and humidity conditions. The rotating table 4 has good rotational stability. The testing table 10 cooperates with the electric telescopic rod 15 and the ring-shaped clamping plate 151 to fix the fabric abrasion resistance test. The height of multiple grinding plates is adjustable, which can adapt to the adjustable and controllable friction of fabrics of different thicknesses for multiple sets of abrasion resistance comparison tests.
