Description

Technical Field

[0001] The invention relates to the technical field of textile testing, and in particular to a textile antifouling performance testing device and a testing method. Background Art

[0002] Anti-fouling textiles have been developed rapidly. For example, they are used to make work clothes for workers who frequently come into contact with mineral oils and animal and vegetable oils. They are also used in ordinary ready-made clothes, jackets, casual wear, and sleeping bags. Anti-fouling textiles can be divided into anti-liquid dirt and anti-solid dirt according to the different pollutants. Liquid dirt refers to oil-soluble and water-soluble liquid dirt such as cooking oil, soy sauce, motor oil, coffee, etc. Solid dirt generally refers to solid dirt such as atmospheric dust, rust, pigments, and small black particles formed by the combination of automobile exhaust and air dust. Liquid dirt and solid dirt are contaminated in different ways, so the detection methods are also different. At this stage, the detection method of anti-liquid dirt performance is relatively mature, and there are standard detection methods.

[0003] However, traditional manual testing requires the preparation of a variety of test materials. In addition, standard stickers are required to wipe the stains on the sample multiple times during the anti-fouling performance test. The repeated wiping process is inefficient and difficult to control the strength. It is difficult to achieve uniformity during the dripping and smearing process, which introduces errors in the test data. At the same time, as the number of textiles submitted for inspection gradually increases, traditional manual testing is less efficient and difficult to meet the requirements of testing speed and accuracy. Summary of the invention

A rotating seat is set to drive the movement of various functional components, and the functional components acting on the sample are switched to achieve a standardized process of dripping, smearing and wiping. At the same time, the operation sequence can be switched to meet different needs. The wiping action on the sample is applied by the wiping part, and the wiping is repeated multiple times to ensure the accuracy of the test data, reduce the manual burden and improve efficiency.

The rotating seat drives the output end, the smearing end and the wiping part to be alternately placed above the carrying plate to alternately drip contaminants, smear and wipe the sample on the carrying plate. An image acquisition component is provided on the side of the carrying plate to obtain image data above the carrying plate.

[0007] Furthermore, the wiping assembly includes a roller and a winding mechanism, one end of the cotton standard lining roll is wound on the roller, the bottom end of the cotton standard lining located on the roller forms a wiping portion, one end of the cotton standard lining is wound on the winding mechanism to recover the cotton standard lining released by the roller, and form a wiping action on the sample in the wiping portion.

[0008] Furthermore, the roller is connected to the end of the lifting mechanism, and the lifting mechanism drives the roller and the wiping part to move so as to apply pressure during the wiping action.

[0009] Furthermore, the carrying plate is mounted on a carrying platform, and a clamp is provided on the carrying platform at a position corresponding to the carrying plate, and the clamp clamps the relative position of the carrying plate sample and the carrying plate.

[0010] Furthermore, the carrying platform is provided with an adjustment mechanism, and the adjustment mechanism drives the carrying plate to move relative to the carrying platform through the clamp to change the relative position of the sample and the carrying platform.

[0011] Furthermore, the image acquisition component is arranged tilted relative to the supporting platform.

[0012] Furthermore, the image acquisition component and the rotating seat are respectively connected to the controller, the image acquisition component is used to collect sample image data on the carrier plate and send it to the controller, and the controller is used to control the rotation of the rotating seat and the dripping, smearing and wiping.

[0013] Furthermore, the dripping assembly includes a contaminant container and a dripping nozzle, the contaminant container is connected to the dripping nozzle, and the dripping nozzle serves as an output section to drip contaminants onto the sample; the smearing assembly includes a smearing drive and a smearing member, and the smearing drive drives the smearing end of the smearing member to act on the sample.

[0014] The second object of the present invention is to provide a method for detecting the antifouling performance of textiles as described in the first object, comprising:

[0015] Arrange the specimen on the load-bearing plate and adjust the rotating seat;

[0016] The output end of the dripping assembly is positioned above the sample, a set amount of contaminant is dripped onto the sample, and an image is collected;

[0017] The smearing end of the smearing component is positioned above the sample, and the smearing end smears the contaminants on the sample;

[0020] Furthermore, the wiping part applies a set pressure to the sample and wipes in the same direction.

[0021] Compared with the prior art, the present invention has the following advantages and positive effects:

[0022] (1) In order to solve the problem of low efficiency in testing the antifouling performance of textiles, a rotating seat is set up to drive the movement of various functional components, and the functional components acting on the sample are switched to realize the standardized process of dripping, smearing and wiping.

DETAILED DESCRIPTION

[0029] Example 1

[0030] In a typical embodiment of the present invention, Figure 1 As shown, a device for detecting the antifouling performance of textiles is provided.

[0031] like Figure 1 The textile antifouling performance testing device shown is used to test the antifouling performance of textiles. At the same time, after dropping the stain on the sample and before applying it, image acquisition can be performed to obtain the anti-wetting performance of the sample. After applying the stain, the stain is spread to the required range and wiped. After repeated wiping, the distribution state of the stain on the sample is obtained, so as to evaluate the antifouling performance of the textile.

[0032] like Figure 1 As shown, the textile antifouling performance testing device mainly includes a functional component for testing, a rotating seat 18 for carrying the functional component, and a supporting plate for carrying the sample. Among them, there are multiple functional components, which can realize the dripping, smearing and wiping of the contaminants on the sample on the supporting plate, realizing the process of simulating manual testing, and the dripping of contaminants is more accurate, the smearing is more uniform and controllable, and the wiping is more reasonable and effective. The rotating seat 18 rotates to drive the functional components to switch positions, so that in different steps, the corresponding functional components can move to the position of the supporting plate to apply dripping, smearing or wiping actions to the sample.

[0033] For the functional components in this embodiment, three types are set, namely, a dripping component, a smearing component and a wiping component, which respectively replace manual dripping, smearing and wiping processes. The above three functional components are respectively connected to the rotating seat, and the position of the functional components is adjusted by rotating the rotating seat. The three functional components are arranged around the rotating seat, such as Figure 1 As shown, the dripping assembly, the smearing assembly and the wiping assembly are arranged at intervals along the circumferential direction and are respectively connected to the rotating seat 18.

[0034] The carrying plate is located below the entire functional component for easy operation. The dripping component is provided with an output end to output the contaminant to the sample. The smearing component is provided with a smearing end, which can act on the contaminant on the sample to spread it evenly. The wiping component is provided with a wiping part 20, which can wipe the contaminant after smearing to meet the requirements of the detection standard.

[0035] like Figure 1 As shown, the rotating seat 18 drives the output end, the smearing end and the wiping part 20 to be alternately placed above the carrier plate to alternately add contaminants, smear and wipe the sample on the carrier plate. An image acquisition component is provided on the side of the carrier plate to obtain image data above the carrier plate.

[0036] The image acquisition component and the rotating seat 18 are respectively connected to the controller. The image acquisition component is used to collect sample image data on the carrier plate and send it to the controller. The controller is used to control the rotation, dripping, smearing, and wiping of the rotating seat 18. The controller is connected to the rotation controller 13 to control the rotation process of the rotating seat 18.

[0037] During the test, it is necessary to record the test time, the number of wipes and the anti-fouling grade of the evaluation, so a corresponding display 4 is also configured. The display 4 is connected to the controller, and the display 4 is provided with a first display area 5, a second display area 6, a third display area 7 and a fourth display area 8. According to the needs, different display areas are configured to display different contents, such as configuring the first display area 5 to display the test time, configuring the fourth display area 8 to display the anti-fouling grade, or configuring the second display area 6 to display the number of tests, etc.

[0038] Each functional component is configured according to the standard requirements. The dripping component includes a contaminant container 14 and a dripping nozzle 16. The contaminant container 14 is connected to the dripping nozzle 16. The dripping nozzle 16 is used as an output section to drip contaminants to the sample. In this embodiment, the dripping tool is mainly a dropper. The contaminant container 14 is connected to the dropper. The output end of the dropper is used as the dripping nozzle 16. The dropper is provided with a dripping switch 15. When the wiping method in FZ / T01118-2012 and the standard of FZ / T24012-2010 (Appendix A) are used in the liquid contamination process, the dropper drips about 0.05 ml (1 drop) of dirty liquid in the center of the sample. When the liquid contamination method in GB / T30159.1-2013 is used, the dropper drips about 1 ml (2 consecutive drops) of dirty liquid in the center of the sample.

[0039] In this embodiment, the coating assembly includes a coating drive and a coating member, and the coating drive drives the coating end of the coating member to act on the sample. The coating assembly can use a glass rod 17, and the coating drive can use a swing mechanism, such as a motor driving the glass rod 17 through an eccentric wheel, so that the droplets are evenly coated in a circle with a diameter of 10 mm.

[0040] In this embodiment, the wiping assembly includes a roller 19 and a winding mechanism. One end of the cotton standard lining 24 is wound around the roller 19. The bottom end of the cotton standard lining 24 on the roller 19 forms a wiping portion 20. One end of the cotton standard lining 24 is wound around the winding mechanism to recover the cotton standard lining 24 released from the roller 19, and a wiping action is formed on the sample at the wiping portion 20.

[0041] The wiping assembly is equipped with a winding roller 19 and a winding mechanism, and the wiping part 20 is updated in the process of releasing and rewinding. The wiping action and the updating of the wiping part 20 are performed alternately, so that the winding roller 19 releases the cotton standard lining 24 that has not been wiped and contaminated, and the cotton standard lining 24 that has been wiped and contaminated is moved and rewound after wiping, so as to keep the cotton standard lining 24 used for wiping in a clean state, avoid repeated replacement of the cotton standard lining 24, and improve the wiping efficiency.

[0042] In addition, the roller 19 is connected to the end of the lifting mechanism 23, and the lifting mechanism 23 drives the roller 19 and the wiping part 20 to move so as to apply pressure during the wiping action.

[0043] The wiping portion 20 is located at the bottom end of the roller 19. When the cotton standard lining 24 on the roller 19 is gradually released to raise the wiping portion 20, in order to ensure the wiping effect, the lifting mechanism 23 is used to adjust the position of the roller 19, so that the bottom end of the roller 19 maintains good contact with the sample during wiping, ensuring that the pressure of each wiping is close to the same.

[0044] In this embodiment, the wiping assembly simulates the manual inspection process, and the cotton standard liner 24 is used to wipe the stained part in the same direction. After each wiping, the cotton standard liner needs to be changed to another clean part and continue wiping, and a total of 30 times of wiping.

[0045] The load-bearing plate is mounted on the load-bearing platform 11, and a clamp 22 is provided at the load-bearing platform 11 corresponding to the load-bearing plate position, and the clamp 22 clamps the relative position of the load-bearing plate sample and the load-bearing plate; an adjustment mechanism is provided on the load-bearing platform 11, and the adjustment mechanism drives the load-bearing plate to move relative to the load-bearing platform 11 through the clamp 22 to change the relative position of the sample and the load-bearing platform 11. In this embodiment, the load-bearing platform 11 is arranged on the test bench 9, and a moving wheel 2 is provided at the bottom of the test bench 9 through the base 1 to facilitate position adjustment. At the same time, a liquid-absorbing filter paper 12 is also arranged on the test bench 9, and a movable ball 10 is used as an adjustment roller to drive the overall position adjustment of the load-bearing platform 11.

[0046] The image acquisition component is arranged obliquely relative to the carrier 11 to collect image data from the side. The image acquisition component can use a camera 21 to shoot videos and pictures.

[0047] In actual operation, the power is turned on and the power switch 3 is turned on. According to the standard FZ / T01118-2012, the test is carried out. The sample is arranged on the carrier plate according to the standard requirements, and the liquid absorbing filter paper 12 is arranged on the side of the carrier plate. The camera takes pictures, and the old soy sauce is poured into the contaminant container 14 and enters the dropper. The drip switch 15 controls the output to 0.5 ml (the dripper is about 1 cm away from the sample).

[0048] After the camera 21 acquires the image data, for the droplets that cannot spread out by themselves, the rotary controller 13 controls the rotating seat 18 to rotate and adjust the position of the functional component. In this embodiment, the smearing component is moved to the sample position by rotating 120° in the horizontal plane, and the droplets are evenly applied to a circular area with a diameter of about 10 mm through the glass rod 17. If the droplets spread out by themselves, no smearing operation is required;

[0049] For the samples that need to be dried, the test bench 9 is moved to the drying position by the moving wheel 2. After drying, the camera 21 takes pictures again and rates. The rotary controller 13 controls the rotating seat 18 to move so that the wiping component is located close to the sample. The cotton standard lining 24 is used to wipe the stained part in the same direction and apply pressure. Since the sample is clamped on the carrier plate and can be fixed in the current position, the cotton standard lining 24 needs to be changed to another clean part for continuous wiping each time. In order to ensure good contact during wiping, a certain pressure can be applied by a telescopic component, such as a cylinder, a spring, etc., so that the cotton standard lining 24 forms a surface contact with the sample. The sample is wiped 30 times in total. Of course, the number of wiping times can also be adjusted according to needs. The camera 21 takes pictures again and rates. The evaluation is displayed on the display screen.

[0050] For the rating process, it can be considered that the collected images are rated according to the reference standards and then displayed.

[0051] Example 2

[0052] In another typical embodiment of the present invention, Figure 1 As shown, a detection method for a textile antifouling performance detection device is provided.

[0053] The textile antifouling performance testing device as in Example 1 is used, comprising:

[0054] Arrange the specimen on the load-bearing plate and adjust the rotating seat;

[0055] The output end of the dripping assembly is positioned above the sample, a set amount of contaminant is dripped onto the sample, and an image is collected;

[0056] The smearing end of the smearing component is positioned above the sample, and the smearing end smears the contaminants on the sample;

[0057] The wiping part 20 of the wiping assembly is located above the sample, and the wiping part 20 acts on the smeared contaminant, and the wiping is repeated for multiple times. When wiping, the wiping part 20 applies a set pressure to the sample and wipes in the same direction;

[0058] The sample images after wiping are collected and analyzed to obtain the antifouling performance parameters.

[0059] In addition, when testing according to FZ / T24012-2010 standard, the process is as follows:

[0060] Turn on the power switch 3, select the standard FZ / T24012-2010, place the sample on the load board according to the standard requirements and arrange it on the load platform 11 and the test platform 9, take pictures continuously with the camera, and choose to pour soy sauce, vinegar and fresh milk into the contamination container 14 according to the standard requirements. In this embodiment, the contamination container 14 is a detachable funnel device, the contamination container 14 is connected to the dropper, and the drip switch 15 controls the amount of 1ml (the dropper is about 1cm away from the sample). The display 4 displays the timing, and three places can be dripped on the sample at an interval of 4cm in sequence. The wetting of the droplets within 30s is observed at an interval of about 45° on the surface of the sample. The anti-contamination level is the highest level 5 and the lowest level 1.

[0061] Among them, the anti-contamination grades are divided as follows:

[0062] Level 1: The droplet wets the entire surface of the fabric in contact with the droplet.

[0063] Level 2: Half of the surface area of ​​the fabric in contact with the droplet is wetted

[0064] Level 3: One third of the surface area of ​​the fabric in contact with the droplet is wetted

[0065] Level 4: One quarter of the surface area of ​​the droplet in contact with the fabric is wetted

[0066] Level 5: No wetting between the droplet and the fabric surface

[0067] In addition, for the liquid contamination method in GB / T30159.1-2013, the following testing process is included:

[0068] Turn on the power switch 3, select the standard GB / T30159.1-2013, place the sample on the load board according to the standard requirements and place it on the test bench 9, take a photo with a camera, select the first-level squeezed finished oil that meets GB1534-2003 or the high-salt dilute fermented soy sauce (old soy sauce) that meets GB18186-2000, pour it into the detachable funnel device according to the standard requirements, enter the dropper, and the drip switch 15 controls the output of 0.5ml (the dripper is about 6mm away from the sample). The stopwatch starts timing, and by adjusting the position of the sample, multiple droplets are dripped on the sample. In this embodiment, the multiple droplets dripped in sequence are at least 50mm apart, and there are three droplets in total. The wetting of the droplets within 30s is observed at an angle of about 45° on the surface of the sample. Estimate the anti-contamination level based on the wetting area, with the highest level being 5 and the lowest level being 1.

[0069] It can be understood that in this embodiment, the contamination level is evaluated according to the existing standards, the main frame marking method is used, the area range is set, and the proportional relationship between the wetted area and the set range in the acquired image is observed.

[0070] Level 1: The droplet wets the entire surface of the fabric in contact with the droplet.

[0071] Level 2: Half of the surface area of ​​the fabric in contact with the droplet is wetted

[0072] Level 3: One third of the surface area of ​​the fabric in contact with the droplet is wetted

[0073] Level 4: One quarter of the surface area of ​​the droplet in contact with the fabric is wetted

[0074] Level 5: No wetting between the droplet and the fabric surface

[0075] Other matters not introduced shall be executed and analyzed according to the current manual operation standards.
