Description

Technical Field

[0001] This utility model relates to the field of fabric testing technology, specifically to a testing device for mercerized cotton fabrics that are resistant to pilling and shrinkage. Background Technology

[0002] As living standards continue to improve, people are paying more attention to environmental protection, comfort, and aesthetics when choosing bedding fabrics. However, existing products on the market often fail to meet these requirements. Knitted cotton bedding fabric, woven on a circular knitting machine, has advantages such as strong water absorption and a soft, close-fitting feel. Knitted cotton also has good dyeability, resulting in vibrant colors and high colorfastness. However, due to the structural characteristics of knitted cotton, the shrinkage rate of domestically produced knitted cotton is generally above the national standard of 7%, failing to reach the first-class grade. Furthermore, its pilling resistance typically only reaches the national standard of 2-2.5, and its hand feel is not soft and delicate enough. Mercerized cotton knitted fabric cannot achieve the required width for bedding, preventing existing manufacturers from producing first-class knitted bedding that meets national standards.

[0003] For example, application number CN211697498U discloses a fabric light transmittance detection system, including a machine body and an L-shaped frame. The top surface of the machine body is a detection platform, and the L-shaped frame is fixed to the surface of the detection platform. A light source assembly is installed on the L-shaped frame. A driven roller and a driving roller are respectively installed at the first and last ends of the top surface of the detection platform. A drive mechanism for driving the driving roller to rotate is also installed on the machine body. A mounting frame is hinged to the first end of the detection platform, and a guide roller is installed on the mounting frame. An adjustable support rod is connected between the machine body and the mounting frame. The fabric light transmittance detection equipment of this utility model is convenient to detect and easy to operate. It is easy to adjust the distance between the light emitter and the light receiver. Through the set guide roller and adjustable support rod, the height of the guide roller can be adjusted for different fabrics, so that the fabric can be kept in a taut state at any rotation speed of the driving roller, thereby improving the detection accuracy.

[0004] However, this fabric light transmittance testing system can only test the light transmittance of the fabric and cannot test the pilling resistance of mercerized cotton fabric. The test results are limited and do not meet people's needs. Therefore, there is a need for mercerized cotton fabric testing equipment that can test for pilling resistance and shrinkage.

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Example 1

[0027] like Figure 1-5 As shown, the mercerized cotton fabric anti-pilling and shrinkage testing equipment proposed in this utility model includes a machine body 1 and a connecting mechanism disposed inside the machine body 1. The connecting mechanism includes a rotating component, a switching component and a testing component.

[0028] The rotating assembly includes a rotary motor 2, a rotating disk 3, a storage slot 4, a detection disk 5, a fixing ring cover 6, and fastening screws 7. The rotary motor 2 is fixedly installed at the bottom of the machine body 1. The main shaft of the rotary motor 2 is welded to the rotating disk 3. The rotating disk 3 has a storage slot 4 inside, and the detection disk 5 is placed inside the storage slot 4. The detection disk 5 is rotatably connected to the fixing ring cover 6 through threaded engagement. The fixing ring cover 6 is fixedly installed on the rotating disk 3 by the fastening screws 7. During operation, by setting up the rotary motor 2, rotating disk 3, storage slot 4, detection disk 5, fixing ring cover 6, and fastening screws 7, the detection disk 5 can be stably fixed inside the detection disk 5 by screwing the fixing ring cover 6. The fixing ring cover 6 is fixedly installed on the rotating disk 3 by the fastening screws 7, which helps to prevent the fixing ring cover 6 from shaking when the rotary motor 2 is working, and achieves more stable control operation for fabric detection.

[0029] The switching assembly includes a lifting hydraulic press 8, a motor housing 9, a switching motor 10, a switching disc 11, a nylon disc 12, a fabric disc 13, a scraper 14, and a pressure bar 15. The lifting hydraulic press 8 is fixedly installed on the inner top of the machine body 1. The motor housing 9 is welded to the output end of the lifting hydraulic press 8. The switching motor 10 is welded inside the motor housing 9. The switching disc 11 is fixedly installed on the output end of the switching motor 10. Nylon discs 12, fabric discs 13, scrapers 14, and pressure bars 15 are evenly arranged on the end face of the switching disc 11 away from the switching motor 10. During operation, the switching disc 11 is adjusted according to the following parameters: The system includes a lifting hydraulic press 8, a switching motor 10, a switching disc 11, a nylon disc 12, a fabric disc 13, a scraper 14, and a pressure bar 15. The switching motor 10 drives the switching disc 11 to rotate and switch between different nylon discs 12, fabric discs 13, scrapers 14, and pressure bars 15, facilitating the testing of mercerized cotton fabric for anti-pilling, anti-shrinkage, and anti-fuzzing properties. The lifting hydraulic press 8 can lower the switching disc 11 to the upper surface of the fabric 26 to be tested, and apply pressure to quickly check whether mercerized cotton is resistant to pilling, anti-fuzzing, or anti-shrinkage, thus achieving rapid switching and testing control operations.

[0030] Furthermore, a nylon brush 20 is fixedly installed on the lower surface of the nylon disc 12, a fabric abrasive 21 is provided on the lower surface of the fabric disc 13, and a scraper 22 is welded to the lower surface of the scraper frame 14. During operation, by setting the nylon brush 20, the fabric abrasive 21, and the scraper 22, the nylon brush 20 is beneficial for performing anti-pilling detection on the fabric 26 to be tested, and the fabric abrasive 21 and the scraper 22 are beneficial for performing anti-pilling detection on the fabric 26 to be tested, so as to realize the control operation of performing multiple detection methods without changing the fabric 26 to be tested.

[0031] Furthermore, a transparent protective cover 23 is provided on the front surface of the machine body 1. The transparent protective cover 23 is located on the same horizontal line as the detection plate 5. During operation, by setting the transparent protective cover 23, the staff can observe and compare the two sets of projections on the background plate 17 through the transparent protective cover 23, and then determine whether the mercerized cotton fabric is resistant to pilling and shrinkage.

[0032] Furthermore, the detection disc 5 is equipped with a support block 24 inside, and a sponge pad 25 is installed on the top of the support block 24. The fabric to be tested 26 is placed on the end face of the sponge pad 25 away from the support block 24. During operation, by setting the support block 24 and the sponge pad 25, the support block 24 can provide rigid support for the fabric to be tested 26, preventing the fabric to be tested 26 from collapsing too much during the test and thus affecting the test results. The sponge pad 25 provides soft support for the fabric to be tested 26, which is conducive to the fabric to be tested 26 bulging during the test, realizing convenient and highly accurate control operation for the test.

[0033] Furthermore, the nylon brush 20 is positioned directly above the fabric 26 to be tested. The diameters of the nylon brush 20, fabric abrasive 21, and scraper 22 are all smaller than those of the fabric 26 to be tested. The nylon brush 20, fabric abrasive 21, and scraper 22 can test the central area of ​​the fabric 26 to be tested, avoiding the problem of inaccurate test results caused by uneven friction around the fabric 26. The force test is performed on the center of the fabric 26 to be tested, making the test results more intuitive and accurate. Example 2

[0034] like Figure 1-5As shown, the mercerized cotton fabric anti-pilling and shrinkage testing device proposed in this utility model, compared with Embodiment 1, is another implementation of this utility model. The testing components include a spotlight 16, a background plate 17, a comparison column 18, and a comparison fabric tray 19. The spotlight 16 is installed on the left side wall inside the machine body 1, and the background plate 17 is installed on the right side wall inside the machine body 1. The spotlight 16 and the background plate 17 are symmetrically arranged about the rotating disk 3. The comparison column 18 is installed behind the rotating motor 2. The comparison fabric tray 19 is fixedly installed on the upper surface of the comparison column 18. During operation, by setting up the spotlight 16, the background plate 17, the comparison column 18, and the comparison fabric tray 19, the spotlight 16 emits illumination light, which projects the comparison fabric and the fabric to be tested 26 in the comparison fabric tray 19 onto the background plate 17. The operator can observe the two sets of projections on the background plate 17 through the transparent protective cover 23 for comparison, thereby determining whether the mercerized cotton fabric is resistant to pilling and shrinkage.

[0035] Furthermore, the fact that the comparison column 18 and the rotary motor 2 are located on the same axis ensures that the comparison fabric tray 19 and the detection tray 5 above the comparison column 18 are on the same vertical axis, and that the comparison fabric tray 19 and the detection tray 5 are on the same horizontal line. This is beneficial for the comparison fabric and the fabric to be detected 26 inside the comparison fabric tray 19 to be on the same horizontal line, which is convenient for subsequent projection for observation and comparison.

[0036] During operation, the support block 24 and the sponge pad 25 are first placed inside the detection plate 5. Then, the fabric to be tested 26 is placed on the sponge pad 25 and screwed onto the detection plate 5 by the fixing ring cover 6. Next, the detection plate 5 is placed inside the storage slot 4. Then, the fixing ring cover 6 is fixed onto the rotating plate 3 by the fastening screw 7. The rotating motor 2 starts to rotate, causing the fabric to be tested 26 inside the rotating plate 3 to rotate as well, which facilitates the subsequent testing of the fabric to be tested 26.

[0037] Next, the switching motor 10 inside the motor housing 9 starts to rotate, first rotating the nylon brush 20 on the nylon disc 12 to directly above the fabric 26 to be tested. Then, the lifting hydraulic press 8 starts to work, driving the nylon brush 20 downward to the upper surface of the fabric 26 to be tested. The nylon brush 20 performs anti-pilling testing on the fabric 26 to be tested. After rotating for a certain period of time, it stops, and the anti-pilling test operation is completed. When anti-pilling testing is required, the switching motor 10 works to rotate the fabric abrasive 21 below the fabric disc 13 to directly above the fabric 26 to be tested, or the scraper 22 below the scraper frame 14. Rotate the hydraulic press 8 to directly above the fabric 26 to be tested. The lifting hydraulic press 8 then moves the fabric abrasive 21 or scraper 22 downwards to the upper surface of the fabric 26 to be tested. The fabric abrasive 21 or scraper 22 performs anti-pilling testing on the fabric 26 to be tested. After rotating for a certain period of time, the operation is stopped, and the anti-pilling test is completed. Then, switch the motor 108 to rotate the pressure bar 15 to directly above the fabric 26 to be tested. The lifting hydraulic press 8 then moves the pressure bar 15 downwards to the upper surface of the fabric 26 to be tested. The pressure bar 15 performs shrinkage testing on the fabric 26 to be tested. After applying pressure for a certain period of time, the operation is stopped, and the shrinkage test is completed.

[0038] Finally, the illumination spotlight 16 emits illumination light, which projects the comparison fabric and the fabric to be tested 26 in the comparison fabric tray 19 onto the background board 17. The staff can observe the two sets of projections on the background board 17 through the transparent protective cover 23 for comparison, thereby determining whether the mercerized cotton fabric is resistant to pilling and shrinkage.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
