Description

Technical Field

[0001] This invention relates to the field of textile quality testing technology, and in particular to a textile quality testing device and method. Background Technology

[0002] Textiles refer to various products made by processing fibers or yarns through a series of processes such as spinning, weaving, dyeing, printing and finishing. As consumers' requirements for textile quality are increasing, textile quality has become an important factor for the survival and development of enterprises in the industry. In order to ensure that the quality of textiles meets consumer needs, it is necessary to conduct quality testing on the produced textiles.

[0003] The quality testing of textiles is mainly divided into physical performance testing and chemical performance testing. Among the physical performance testing, the abrasion resistance testing of textiles is a crucial step, as it directly relates to the service life of textiles, user experience, and market competitiveness.

[0004] Currently, in the process of abrasion resistance testing of textiles, it is difficult to realistically simulate the complex stresses experienced by textiles under actual use conditions, resulting in insufficient accuracy of the final test evaluation. Moreover, during the abrasion resistance testing process, due to friction, lint and heat are generated on the textiles. Firstly, the adhesion of lint participates in subsequent friction, thereby aggravating the actual wear of the textile fabric. Secondly, excessively high temperatures can cause unexpected wear on the textiles, thus reducing the accuracy of the test results. Therefore, a textile quality testing device and method are proposed. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that existing technologies cannot realistically simulate the complex stress, friction-induced lint and heat generated by textiles under actual use conditions, which ultimately reduces the accuracy of test results. Therefore, this invention proposes a textile quality testing device and method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A textile quality testing device includes a testing chamber and four symmetrically distributed clamping seats. An electric push rod is fixedly connected to the top of the testing chamber. A bidirectional spring telescopic rod is fixedly connected to the telescopic end of the electric push rod and to the bottom of the inner cavity of the testing chamber. The four clamping seats are respectively fixed to the telescopic ends of two sets of bidirectional spring telescopic rods. A piston box is fixedly connected to the upper and lower parts of the inner wall of the testing chamber, and an air-filling part for injecting air into the bidirectional spring telescopic rods is provided inside the piston box. A movable seat is also included. A reciprocating screw is rotatably connected inside the testing chamber, and a movable block is threaded onto the reciprocating screw. The side wall of the movable block fits against the inner wall of the testing chamber. The movable seat is fixed to the movable block, and a friction part for simulating abrasion resistance testing of textiles is provided inside the movable seat. Air guide boxes are fixedly connected to both sides of the outer wall of the testing chamber, and a flow guide part is provided inside the air guide box to directionally absorb debris and heat generated by the friction part.

[0008] To improve the simulation effect of wear resistance testing environment, preferably, the friction part includes two sets of transverse rubbing plates, and the top and bottom of the movable seat are slidably connected with positioning columns. The ends of the positioning columns are fixedly connected to the transverse rubbing plates.

[0009] Furthermore, a longitudinal groove is formed on the friction surface of the transverse wiping plate, and a longitudinal wiping plate is slidably connected in the longitudinal groove. The longitudinal groove is longer than the longitudinal wiping plate. A second spring is fixedly connected between the end of the longitudinal wiping plate and the transverse wiping plate. An inclined protrusion is fixedly connected to the top of the upper transverse wiping plate and the bottom of the lower transverse wiping plate. A protrusion rack is fixedly connected to the upper and lower parts of the inner cavity of the detection box. The inclined protrusion cooperates with the protrusion rack, that is, when the longitudinal wiping plate moves along the long axis of the protrusion rack, the inclined protrusion will slide back and forth in a direction perpendicular to the protrusion rack.

[0010] To ensure the smoothness of textiles during abrasion resistance testing, preferably, the inflation part includes a piston plate slidably connected inside a piston box. A fourth spring is fixedly connected between the piston plate and the inner wall of the piston box. Inflation tubes are fixed and connected to the side walls of both sets of piston boxes. The other end of the inflation tube is connected to the middle cavity of its corresponding bidirectional spring telescopic rod. A fixed protrusion is fixedly connected to the top of the moving block. A movable protrusion is fixedly connected to the side of both sets of piston plates facing the fixed protrusion. The fixed protrusion and the movable protrusion cooperate with each other, that is, when the moving block carries the fixed protrusion past the movable protrusion, it will push the movable protrusion to slide away from the fixed protrusion.

[0011] To improve the clamping strength of textiles in abrasion resistance testing, preferably, the clamping seat has a fastening groove, a fastening plate is slidably connected in the fastening groove, a third spring is fixedly connected between the fastening plate and the inner wall of the fastening groove, and the fastening groove is connected to the middle cavity of the bidirectional spring telescopic rod connected to it. An air replenishment pipe is fixed and connected to the air inflator, and both the air inflator and the air replenishment pipe are equipped with a one-way valve.

[0012] To improve the accuracy of wear resistance test results, preferably, the guide section includes a linkage shaft, which is rotatably connected inside the air guide box. A guide vane is fixedly connected to one end of the linkage shaft, and a dust filter is fixedly connected to the outer end of the air guide box. The other end of the linkage shaft passes through the test chamber and is connected to the reciprocating lead screw via a bevel gear set. An air extraction pipe is fixedly connected to both the top and bottom of the movable seat, and the other end of the air extraction pipe communicates with the corresponding inner cavity of the air guide box.

[0013] Furthermore, a guide groove is provided on the friction surface of the transverse wiping plate, the end of the guide groove is connected to the end of the longitudinal sliding groove, and the input end of the air extraction pipe is aligned with the end of the longitudinal sliding groove.

[0014] To maintain the horizontality of the fixed textile, preferably, the detection box has limiting grooves on both sides corresponding to the number of movable seats, and each set of limiting grooves is slidably connected to a limiting slide plate, the end of which is fixedly connected to the side wall of its corresponding movable seat.

[0015] In order to test the electrostatic intensity generated when textiles are rubbed, preferably, a non-contact electrometer is fixedly connected to the top of the movable base, and the two sets of sensing terminals of the non-contact electrometer are respectively located on both sides of the top of the movable base.

[0016] A method for quality testing of textiles, comprising the following steps:

[0017] Step 1: Fix the sample of the textile fabric to be tested onto the clamp;

[0018] Step 2: Conduct abrasion resistance simulation tests on the surface of the textile fabric;

[0019] Step 3: Directional adsorption of debris and heat generated during the abrasion resistance test;

[0020] Step 4: In the abrasion resistance test, the drive clamp pulls the textile fabric to both sides to keep it flat;

[0021] Step 5: In the abrasion resistance test, the electrostatic properties generated on the surface of the textile fabric are tested.

[0022] Compared with the prior art, the present invention provides a textile quality testing device and method, which has the following beneficial effects:

[0023] 1. This textile quality testing equipment applies transverse and longitudinal friction to the textile fabric by reciprocating the transverse and longitudinal rubbing plates in mutually perpendicular directions. This more realistically simulates the complex stress state of the fabric under actual use conditions, so as to conduct a more comprehensive and accurate abrasion resistance evaluation, thereby improving the quality testing accuracy of textiles.

[0024] 2. This textile quality testing equipment generates negative pressure suction at two sets of transverse rubbing plates through the rotation of the guide vanes. This suction carries away the debris and heat generated by friction. Firstly, it reduces the possibility of debris acting as additional abrasive in subsequent friction, thus reducing the actual wear of the textile fabric. Secondly, it maintains the textile sample at a relatively stable temperature level, effectively preventing unexpected wear caused by overheating. This significantly improves the accuracy of the test results.

[0025] 3. This textile quality testing equipment, through the cooperation of the moving cam, the fixed cam, the piston plate and the fourth spring, can continuously inject gas into the bidirectional spring telescopic rod and the fastening groove during the abrasion resistance test. First, it causes the clamping seats on both sides to move towards the side of the stretched textile fabric, ensuring that the textile fabric always remains in a taut and flat state, thus improving the abrasion resistance test effect. Second, it pushes the fastening plate downward to further clamp the textile fabric, thereby improving the fixing effect of the textile fabric. Attached Figure Description

Therefore, they should not be construed as limitations on this invention.

[0038] Example 1:

[0039] Reference Figures 1-9 A textile quality testing device includes a testing box 1 and four symmetrically distributed clamping seats 2. An electric push rod 21 is fixedly connected to the top of the testing box 1. Bidirectional spring telescopic rods 22 are fixedly connected to the telescopic ends of the electric push rods 21 and the bottom of the inner cavity of the testing box 1. The four clamping seats 2 are respectively fixed to the telescopic ends of two sets of bidirectional spring telescopic rods 22. Piston boxes 23 are fixedly connected to the upper and lower parts of the inner wall of the testing box 1. Piston boxes 23 contain springs that extend into the bidirectional spring telescopic rods 22. An air-filling section for airflow; a movable seat 3; a reciprocating screw 31 rotatably connected inside the test box 1; a movable block 32 threaded onto the reciprocating screw 31; the side wall of the movable block 32 fitting against the inner wall of the test box 1; the movable seat 3 fixed on the movable block 32; and a friction section for simulating abrasion resistance testing of textiles provided inside the movable seat 3; wherein, air guide boxes 4 are fixedly connected to both sides of the outer wall of the test box 1; and a guide section is provided inside the air guide box 4 for directional adsorption of debris and heat generated by the friction section.

[0040] Reference Figure 1 , Figures 4-6The friction part includes two sets of transverse rubbing plates 5. Positioning posts 51 are slidably connected to the top and bottom of the movable seat 3. The ends of the positioning posts 51 are fixedly connected to the transverse rubbing plates 5. A first spring 52 is sleeved on the outside of the positioning posts 51 located between the transverse rubbing plates 5 and the movable seat 3. The two ends of the first spring 52 are fixedly connected to the transverse rubbing plates 5 and the movable seat 3, respectively. A drive motor 53 is fixedly connected to the outer wall of the detection box 1. The output shaft of the drive motor 53 is fixedly connected to the end of the reciprocating lead screw 31. The inner ends of the two sets of transverse rubbing plates 5 are in contact with the inner wall of the movable seat 3. The outer ends of the two sets of transverse rubbing plates 5 are arranged in a figure-eight shape, which facilitates the laying of textile fabric between the two sets of transverse rubbing plates 5. A longitudinal groove 54 is provided on the friction surface of the transverse rubbing plates 5, and a longitudinal rubbing plate is slidably connected within the longitudinal groove 54. 541, and the longitudinal groove 54 is longer than the longitudinal wiping plate 541. A second spring 55 is fixedly connected between the end of the longitudinal wiping plate 541 and the transverse wiping plate 5. An oblique protrusion 56 is fixedly connected to the top of the upper transverse wiping plate 5 and the bottom of the lower transverse wiping plate 5. A protrusion rack 57 is fixedly connected to the upper and lower parts of the inner cavity of the detection box 1. The oblique protrusion 56 cooperates with the protrusion rack 57. That is, when the longitudinal wiping plate 541 moves along the long axis of the protrusion rack 57, the oblique protrusion 56 will slide back and forth in a direction perpendicular to the protrusion rack 57. Cotton friction cloth is fixed on the friction surfaces of the transverse wiping plate 5 and the longitudinal wiping plate 541. In addition, a limit post is slidably connected in the upper longitudinal groove 54, and the limit post passes through the oblique protrusion 56. That is, the oblique protrusion 56 carries the longitudinal wiping plate 541 to slide along the limit post.

[0041] With the above-described structure, the drive motor 53 is activated, causing the reciprocating screw 31 to rotate. At this time, the moving block 32, along with the moving seat 3, slides back and forth along the reciprocating screw 31, causing the cotton friction cloth on the friction surface of the transverse rubbing plate 5 to perform transverse reciprocating friction on the textile fabric. Simultaneously, during the movement of the transverse rubbing plate 5, the oblique protrusion 56 moves along the protrusion rack 57, and in conjunction with the second spring 55, causes the longitudinal rubbing plate 541 to move back and forth within the longitudinal groove 54, causing the cotton friction cloth on the friction surface of the longitudinal rubbing plate 541 to perform longitudinal reciprocating friction on the textile fabric. In summary, transverse and longitudinal friction are applied to the textile fabric simultaneously, thus more realistically simulating the complex stress state experienced by the fabric under actual use conditions, enabling a more comprehensive and accurate assessment of abrasion resistance, thereby improving the quality inspection effect of textiles. Furthermore, the two sets of sensing ends of the non-contact electrometer 9 detect the electrostatic intensity generated by the friction of the textile fabric in real time, thereby assessing the safety of the textile fabric in sensitive environments and the user's wearing comfort, further improving the comprehensiveness of textile quality inspection.

[0042] Reference Figure 3 , Figure 5 and Figure 8The inflation section includes a piston plate 6, which is slidably connected within a piston box 23. A fourth spring 64 is fixedly connected between the piston plate 6 and the inner wall of the piston box 23. Inflation pipes 61 are fixedly connected to the side walls of both sets of piston boxes 23. The other end of the inflation pipe 61 is connected to the middle cavity of its corresponding bidirectional spring telescopic rod 22. A flexible hose is used for the section of the inflation pipe 61 near the bidirectional spring telescopic rod 22 to facilitate the lifting and lowering of the upper bidirectional spring telescopic rod 22. A fixed protrusion 62 is fixedly connected to the top of the moving block 32. Both sets of piston plates 6 are fixedly connected to the side facing the fixed protrusion 62. A fixed protrusion 63 is connected to the fixed protrusion 62. The fixed protrusion 62 and the movable protrusion 63 cooperate with each other. That is, when the moving block 32 carries the fixed protrusion 62 past the movable protrusion 63, it will push the movable protrusion 63 to slide away from the fixed protrusion 62. A fastening groove 24 is opened in the clamping seat 2. A fastening plate 241 is slidably connected in the fastening groove 24. A third spring 242 is fixedly connected between the fastening plate 241 and the inner wall of the fastening groove 24. The fastening groove 24 is connected to the middle cavity of the bidirectional spring telescopic rod 22 connected to it. An air replenishment pipe 611 is fixed and connected to the inflation pipe 61. A one-way valve is provided in both the inflation pipe 61 and the air replenishment pipe 611.

[0043] It should be noted that the one-way valve in the inflation pipe 61 can only allow the gas in the piston box 23 to enter the middle cavity of the bidirectional spring telescopic rod 22; the one-way valve in the air supply pipe 611 can only allow external airflow to supplement the piston box 23.

[0044] With the above structure, when the moving block 32 moves to the middle of the detection box 1, the fixed protrusion 62 and the moving protrusion 63 will come into contact and squeeze, causing the moving protrusion 63 to push the piston plate 6 to slide towards the side that compresses the fourth spring 64, thereby compressing the gas in the piston box 23 and opening the one-way valve in the inflation pipe 61, so that the compressed gas enters the middle cavity of the bidirectional spring telescopic rod 22 and the fastening groove 24 along the inflation pipe 61, thereby increasing the internal air pressure of both, firstly causing the bidirectional spring telescopic rod 22... The telescopic end pushes out to both sides, pulling the two clamping seats 2 simultaneously towards the side of the stretched textile fabric. This prevents the threads in the textile from becoming loose and elongated during the abrasion resistance test, ensuring that the textile fabric remains taut and flat for continuous abrasion resistance testing. Secondly, the increased air pressure in the fastening groove 24 pushes the fastening plate 241 downward, further clamping the textile fabric in the clamping seat 2, ensuring the fixation effect of the textile fabric during continuous abrasion resistance testing. Finally, when the fixed protrusion 62 passes the moving protrusion 63, the rebound action of the fourth spring 64 causes the piston plate 6 to reset, generating a negative pressure suction effect in the piston box 23. This opens the one-way valve in the air supply pipe 611, allowing external airflow to supplement the piston box 23, continuously increasing the air pressure in the middle cavity of the bidirectional spring telescopic rod 22 and the fastening groove 24 during continuous abrasion resistance testing, ensuring the abrasion resistance testing effect.

[0045] Reference Figures 4-6 and Figure 9 The flow guide includes a linkage shaft 7, which is rotatably connected inside the air guide box 4. A flow guide blade 71 is fixedly connected to the end of the linkage shaft 7. A dust filter 41 is fixedly connected to the outer end of the air guide box 4. The other end of the linkage shaft 7 passes through the detection box 1 and is connected to the reciprocating screw 31 through a bevel gear set 72. An air extraction pipe 73 is fixedly connected to the top and bottom of the moving seat 3. The other end of the air extraction pipe 73 is connected to the inner cavity of its corresponding air guide box 4. A flow guide groove 58 is provided on the friction surface of the transverse wiping plate 5. The end of the flow guide groove 58 is connected to the end of the longitudinal slide groove 54, and the input end of the air extraction pipe 73 is aligned with the end of the longitudinal slide groove 54.

[0046] With the above-described structure, during the rotation of the reciprocating screw 31, the transmission action of the bevel gear set 72 drives the linkage shaft 7 to rotate, which in turn drives the guide vane 71 to rotate within the air guide box 4. This generates a negative pressure suction effect on the side of the air guide box 4 near the suction pipe 73. This negative pressure suction effect is transmitted along the two sets of suction pipes 73 to the end of the longitudinal slide groove 54, thereby attracting the airflow between the two sets of transverse rubbing plates 5. This airflow effect carries away the debris and heat generated by friction. Firstly, by carrying away the debris, the risk of debris participating as additional abrasive in subsequent friction and aggravating the actual wear of the textile fabric is reduced, ensuring the accuracy of the test results. Secondly, by carrying away the heat, the textile sample is kept at a relatively stable temperature level, effectively preventing unexpected wear caused by overheating, further improving the accuracy of the test results. Ultimately, the debris will be carried into the air guide box 4 by the airflow, and the airflow will pass through the dust filter 41 and be discharged. The debris will be trapped in the air guide box 4 by the dust filter 41, thereby collecting the debris and improving the cleanliness of the detection area.

[0047] In addition, it should be noted that a gear accelerator is installed on the linkage shaft 7 and a gear reducer is installed on the reciprocating lead screw 31. Both the gear accelerator and the gear reducer adopt existing mature technologies and use the different transmission ratios of the large and small gears to achieve acceleration or deceleration.

[0048] Reference Figure 1 , Figure 2 The detection box 1 has limiting grooves 8 on both sides corresponding to the number of movable seats 3. Each set of limiting grooves 8 is slidably connected to a limiting slide plate 81. The end of the limiting slide plate 81 is fixedly connected to the side wall of the corresponding movable seat 3. The cooperation between the limiting grooves 8 and the limiting slide plate 81 can ensure the straight extension and retraction and lifting of the bidirectional spring telescopic rod 22, that is, keep the fixed textile fabric on the movable seat 3 in a straight state.

[0049] Reference Figure 1 , Figure 6 The top of the movable base 3 is fixedly connected to a non-contact electrometer 9, and the two sets of sensing ends of the non-contact electrometer 9 are located on the top two sides of the movable base 3 respectively.

[0050] With the above structure, during the abrasion resistance test by the reciprocating sliding of the movable seat 3, the non-contact electrometer 9 will move synchronously. During this process, the two sets of sensing ends of the non-contact electrometer 9 will detect the static electricity intensity generated by the friction of the textile fabric in real time, thereby assessing the safety of the textile fabric in sensitive environments and the user's wearing comfort, thus improving the comprehensiveness of textile quality testing.

[0051] Example 2:

[0052] Reference Figures 1-9 Similar to Example 1, but based on Example 1, a method for testing the quality of textiles is proposed, with the following steps:

[0053] Step 1: Fix the sample of the textile fabric to be tested onto the clamp 2;

[0054] Step 2: Conduct abrasion resistance simulation tests on the surface of the textile fabric;

[0055] Step 3: Directional adsorption of debris and heat generated during the abrasion resistance test;

[0056] Step 4: In the abrasion resistance test, drive the clamping seat 2 to pull the textile fabric to both sides to keep it flat;

[0057] Step 5: In the abrasion resistance test, the electrostatic properties generated on the surface of the textile fabric are tested.

[0058] Reference Figures 1-9 In this invention, during use, the electric push rod 21 first pulls the upper bidirectional spring telescopic rod 22 upward, causing the two sets of clamping seats 2 to move upward. Then, the sample of the textile fabric to be tested is laid flat between the two clamping seats 2. At the same time, the two sets of transverse rubbing plates 5 are pushed in the direction of compressing the first spring 52, and the textile fabric is laid flat between the two sets of transverse rubbing plates 5. Then, under the rebound action of the first spring 52, the two sets of transverse rubbing plates 5 will clamp the two sides of the textile fabric. Next, the electric push rod 21 pushes the upper bidirectional spring telescopic rod 22 downward, causing the two sets of clamping seats 2 to move downward, thereby clamping and fixing the textile fabric on the clamping seats 2, completing the fixing work before testing the textile fabric.

[0059] Next, the drive motor 53 is turned on, and under the deceleration transmission of the gear reducer, the reciprocating screw 31 rotates slowly to observe the abrasion resistance of the textile fabric. At this time, the moving block 32 will slide back and forth along the reciprocating screw 31 with the moving seat 3, so that the cotton friction cloth set on the friction surface of the transverse rubbing plate 5 will rub the textile fabric in the transverse direction. At the same time, during the movement of the transverse rubbing plate 5, the oblique protrusion 56 will move along the protrusion rack 57, and with the setting of the second spring 55, the longitudinal rubbing plate 541 will move back and forth in the longitudinal groove 54, so that the cotton friction cloth set on the friction surface of the longitudinal rubbing plate 541 will rub the textile fabric in the longitudinal direction. In summary, the transverse and longitudinal friction effects are applied to the textile fabric simultaneously, so as to more realistically simulate the complex stress state of the fabric under actual use conditions, so as to conduct a more comprehensive and accurate abrasion resistance evaluation, thereby improving the quality inspection effect of textiles. In addition, the two sets of sensing ends of the non-contact electrometer 9 can detect the static electricity intensity generated by friction of textile fabrics in real time, thereby assessing the safety of textile fabrics in sensitive environments and the user's wearing comfort, thus improving the comprehensiveness of textile quality inspection.

[0060] Meanwhile, during the rotation of the reciprocating screw 31, the transmission action of the bevel gear set 72 drives the linkage shaft 7 to rotate. Under the acceleration transmission action of the gear accelerator, the linkage shaft 7 carries the guide vane 71 to rotate rapidly, thereby generating a negative pressure suction effect on the side of the air guide box 4 near the air extraction pipe 73. This negative pressure suction effect is transmitted along the two sets of air extraction pipes 73 to the end of the longitudinal slide groove 54, thereby attracting the airflow between the two sets of transverse rubbing plates 5. This airflow effect carries away the debris and heat generated by friction. First, by carrying away the debris, the possibility of debris participating as additional abrasive in subsequent friction and aggravating the actual wear of the textile fabric is reduced, ensuring the accuracy of the test results. Second, by carrying away the heat, the textile sample is kept at a relatively stable temperature level, effectively preventing unexpected wear caused by overheating, further improving the accuracy of the test results. Ultimately, the debris will be carried into the air guide box 4 by the airflow, and the airflow will pass through the dust filter 41 and be discharged. The debris will be trapped in the air guide box 4 by the dust filter 41, thereby collecting the debris and improving the cleanliness of the detection area.

[0061] In addition, when the moving block 32 moves to the middle of the test box 1, the fixed protrusion 62 and the moving protrusion 63 will come into contact and squeeze, causing the moving protrusion 63 to push the piston plate 6 to slide towards the side that compresses the fourth spring 64, thereby compressing the gas in the piston box 23 and opening the one-way valve in the inflation pipe 61, so that the compressed gas enters the middle cavity of the bidirectional spring telescopic rod 22 and the fastening groove 24 along the inflation pipe 61, thereby increasing the air pressure inside both. First, the telescopic end of the bidirectional spring telescopic rod 22 is pushed out to both sides, pulling the two clamping seats 2 to move towards the side that stretches the textile fabric, avoiding the situation where the yarn in the textile becomes loose and longer during the abrasion resistance test, ensuring that the textile fabric always remains in a taut and flat state for continuous abrasion resistance testing; second, the increased air pressure in the fastening groove 24 will push the fastening plate 241 downward, thereby further clamping the textile fabric in the clamping seat 2, ensuring the fixation effect of the textile fabric during continuous abrasion resistance testing.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
