Background Art

[0002] During their use, textiles will be exposed to various external factors such as light, washing, ironing, sweat, friction and chemicals. Some printed and dyed textiles also undergo special finishing processes, such as resin finishing, flame retardant finishing, sand washing, sanding, etc. This requires that the color of printed and dyed textiles maintain a certain relative fastness, that is, color fastness. Before textile processing, the color fastness of the fabric needs to be tested. The general method of using friction first and then comparing with the color card is to carry out the corresponding detection and processing.

DETAILED DESCRIPTION

[0030] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0031] The first implementation method:

[0032] Figure 1-6 The invention shows an automatic color fastness testing device for fabrics used for textile processing, comprising a testing pool 1 with a cleaning solution inside, an axis frame installed on the top of the testing pool 1 through a pillar, a servo motor 2 installed on one side surface of the axis frame, a linkage shaft rod 5 installed on the inner side of the axis frame, and one end of the linkage shaft rod 5 is connected to the output end of the servo motor 2, gear rings 7 are fixedly sleeved on the surfaces of both end portions of the linkage shaft rod 5, a chain 6 is meshingly connected on the surface of the gear ring 7, and shift plates 4 are connected to both end portions of the chain 6, and friction strips 43 made of rigid material are slidably connected to the surfaces of the two shift plates 4 that are close to each other, and symmetrically arranged limiting push rods 3 are installed on the outer side of the shift plates 4, and the surfaces of the limiting push rods 3 are in contact with the surfaces of the shift plates 4.

[0033] It also includes a detection control system, which is installed on a processor on the surface of the detection pool 1. The processor is connected to a drive control module and a monitoring feedback module, wherein the drive control module is connected to the servo motor 2, the telescopic sleeve 31, the cylinder 84 and the electromagnetic plate 41 signals, and is used to control the start and close of the servo motor 2, the telescopic sleeve 31, the cylinder 84 and the electromagnetic plate 41. The monitoring feedback module includes a pressure sensor installed in a rubber sleeve and a liquid level sensor installed in the detection pool 1, which are used to feedback the pressing force between the limiting rod 3 and the inner wall of the detection pool 1 and the liquid level data in the detection pool 1.

[0034] Specifically, when using the device to test the color fastness of fabrics, the fabric to be tested is folded in half and placed between the two shifting plates 4, and then the distance between the two limiting bars 3 is adjusted so that the limiting bars 3 clamp the two shifting plates 4, so that the shifting plates 4 are in a tightly clamped state;

[0035] The servo motor 2 is started to perform periodic forward and reverse operations, driving the linkage shaft 5 to rotate, and then driving the gear ring 7 to rotate. Under the meshing connection between the gear ring 7 and the chain 6, the end of the chain 6 is driven to perform up and down dislocation processing, and then the fabric inside the dislocation plate 4 is driven to displace up and down. Since there is no limit constraint processing between the fabric and the dislocation plate 4, the dislocation friction in this state is the friction between the fabrics themselves. When the friction between the fabrics themselves caused by human activities such as squatting, bending legs, etc. after the fabrics are made into clothes affects the color fastness, the detection results of this state can be used as a reference;

[0036] The design of the friction strip 43 is similar to the structure of a washboard in life, so when rubbing, the fabric has a two-dimensional friction effect, which can shorten the time required for friction fading compared to the single-dimensional friction of the plane, thereby improving the detection efficiency;

[0037] By utilizing the friction strip 43 made of exposed rigid material, when the displaced plate 4 moves in a displaced manner, the fabric is squeezed and rubbed in two dimensions against the surface of the friction strip 43. At the same time, relative friction occurs synchronously between the facing fabrics. The test results at this time can assist in determining the color fastness of the fabric under external friction.

[0038] The interior of the shift plate 4 is hollow in design, and a plurality of electromagnetic plates 41 are installed on the inner wall of one side of the shift plate 4. A magnetic bracket 42 is installed inside the shift plate 4, and the magnetic bracket 42 is a branch design, and the branch ends of the magnetic bracket 42 are respectively connected to the surface of each friction strip 43.

[0039] Specifically, the electromagnetic plate 41 has two working modes, one is a magnetic attraction mode, and the other is a magnetic repulsion mode;

[0040] In the magnetic repulsion mode, there is a magnetic repulsion effect between the electromagnetic plate 41 and the magnetic bracket 42. As the power of the electromagnetic plate 41 increases, the magnetic bracket 42 drives the friction strip 43 to protrude from the surface of the dislocation plate 4. Therefore, when the dislocation plate 4 moves, the friction between the fabric and the friction strip 43 increases, which can be used to study and determine the influence of the friction strip 43 on the color fastness of the fabric under different slope designs.

[0041] In the magnetic attraction mode, there is a magnetic attraction effect between the electromagnetic plate 41 and the magnetic bracket 42, which can restore the surface of one side of the friction strip 43 to a state flush with the surface of the shift plate 4, which is used to detect the impact of the fabric's own friction on the color fastness.

[0042] A telescopic sleeve rod 31 is connected between the two limiting abutments 3 in the horizontal direction, and the telescopic sleeve rod 31 is located at the periphery of the shift plate 4 . The telescopic sleeve rod 31 is a waterproof micro electric telescopic rod.

[0043] Specifically, in order to meet the requirements of the gap between the shift plates 4 under different use states, the distance between the telescopic sleeve rods 31 is adjusted, thereby ensuring the clamping effect of the limiting rod 3 on the shift plates 4.

[0044] Cylinders 84 are installed around the top of the detection pool 1, and the output end of the cylinder 84 is connected to a connecting rod 83. The ends of the connecting rod 83 are connected to cross bars 8 located on both sides of the limiting rod 3. A through groove 82 is provided inside the cross bar 8, and a tightening screw 81 is installed through the surface of the cross bar 8.

[0045] Specifically, the fabric is passed through the through grooves 82 inside the two cross bars 8, and then the tightening screw 81 is turned to restrict the ends of the fabric. Then, the cylinder 84 is started, and the cross wind bar 8 is driven to reciprocate under the action of the connecting rod 83, so that the fabric is switched between the stretched and straightened state and the rolled and draped state, so that the cleaning solution inside the detection tank can quickly penetrate the fabric. If the color fastness of the fabric is insufficient, the cleaning solution inside the detection tank 1 will change color.

[0046] The end of the limiting rod 3 is connected with a rubber sleeve, and the end of the limiting rod 3 is in pressure contact with the inner wall of the detection pool 1. The friction force between the rubber sleeve and the inner wall of the detection pool 1 is greater than the sum of the gravity of the limiting rod 3 and the telescopic sleeve rod 31.

[0047] Specifically, the bottom of the dislocation plate 4 is connected with an elastic strip, so that after the dislocation plate 4 is lifted to the top of the uppermost limiting rod 3, it can be guided to the middle of the limiting rod 3 when it is lowered, ensuring the effective clamping and restraining treatment between the dislocation plates 4;

[0048] The end of the limiting rod 3 is in pressing contact with the inner wall of the detection pool 1, thereby ensuring its restraining and clamping effect on the shifting plate 4. At the same time, the friction of the rubber sleeve can ensure that the limiting rod 3 will not slide down under the action of gravity.

[0049] The gap between adjacent friction strips 43 in the vertical direction is smaller than the height of a single friction strip 43 , and the ends of the friction strips 43 are chamfered.

[0050] Specifically, the design of the gap value size ensures that the friction strip 43 will not be engaged when the dislocation plate 4 moves, thereby ensuring the normal dislocation movement of the dislocation plate 4.

[0051] Second implementation method:

[0052] Figure 7-9 As shown, a friction strip 43 on the surface of one of the shift plates 4 is of hollow design, and the surface of the friction strip 43 is provided with a plurality of recesses 431 facing the electromagnetic plate 41, a liquid collecting pipe 432 is installed inside the recess 431, a liquid drain pipe 433 is installed through the bottom of the friction strip 43 and the tail end thereof extends through and extends to the outer surface of the shift plate 4, and a pressure sensor electrically connected to the electronic valve is installed at the end of the liquid collecting pipe 432.

[0053] Different from the first embodiment, in the prior art, the rubbed fabric is usually dried after the rubbing treatment and then compared with the color card to obtain the color comparison result. However, in actual operation, in order to simplify the operation, the color fastness can be judged by observing whether the solution changes color after immersion and the degree of color change;

[0054] However, since the volume of the soaking liquid is large and the amount of discoloration is limited, checking the degree of discoloration has certain limitations and is inconvenient to operate, so this implementation method is adopted;

[0055] Specifically, as the shifting plate 4 moves upward, after a period of time, the friction strip 43 without the recess 431 is squeezed and contacted with the friction strip 43 installed. At this time, the pressure sensor senses the squeezing effect, and then sends a start signal to the electronic valve. At this time, the liquid in the fabric is squeezed and enters the friction strip 43 through the liquid collecting pipe 432, and is subsequently discharged through the liquid drain pipe 433. Since the liquid entering the friction strip 43 is squeezed out of the fabric and has not yet been widely diffused and dissolved in the detection pool 1, the degree of discoloration is relatively convenient to check;

[0056] According to the prescribed cycle time, the liquid collecting pipes 432 are started from top to bottom in sequence, so that the discoloring liquid after different friction times can be collected for centralized removal later.

[0057] Electronic valves are installed on the surface of the liquid collecting pipe 432 , and the electronic valves on the surface of the liquid collecting pipe 432 are electrically connected to each other. The cross-sectional area of ​​the recess 431 is less than one third of the cross-sectional area of ​​the friction strip 43 .

[0058] Specifically, the area of ​​the depression 431 is relatively small, and will not interfere with the movement of the fabric on the surface of the shifting plate 4, nor will it damage the friction detection process of the fabric.

[0059] The bottom of the friction strip 43 is designed as a valley bottom, and the installation position of the drain pipe 433 is located at the lowest position of the valley bottom.

[0060] Specifically, the valley bottom design facilitates the centralized discharge of internal fading liquid, making it easier to collect.

[0061] In summary, the present application utilizes the displaced plate 4 and the internal slidable friction strip 43, and can achieve friction between the fabrics themselves through dislocation movement when the friction strip 43 is flush with the surface of the displaced plate 4, thereby obtaining corresponding color fastness test results. When the friction strip 43 protrudes from the surface of the displaced plate 3, the rigid friction and adjustable protrusion degree are utilized to detect the color fastness test results of the fabric under different external friction degrees. In addition, the rapid acquisition of fabric leachate can be utilized to achieve instant sampling, and the color fastness test results after the test can be observed after friction treatment of different lengths, thereby avoiding the problem of difficulty in observing discoloration due to water diffusion, and further comprehensively improving the accuracy of the test results.

[0062] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
