Description

Technical Field

[0001] This invention relates to the field of down jacket fabric testing technology, specifically a device for testing the wrinkle resistance of down jacket fabrics. Background Technology

[0002] The wrinkle resistance of down jacket fabric is one of the important indicators for evaluating its quality, and it is of great significance for improving wearing comfort and maintaining the appearance of the garment.

[0003] Currently, the industry commonly uses the angle of recovery method to test the wrinkle resistance of down jacket fabrics. This method measures only one crease on the fabric each time, which cannot reflect the complex wrinkles that the fabric faces during actual wear. In actual wear, down jacket fabrics often form multiple intersecting wrinkles in a region due to various factors such as human activity, sitting posture, and walking. These wrinkles are not only numerous but also crisscrossed, making them far more complex than a single crease. Although the angle of recovery method can assess the fabric's ability to recover from a single crease to some extent, it cannot intuitively and accurately reflect the wrinkle resistance of down jacket fabrics under regional wrinkle conditions, resulting in a certain deviation between the test results and actual wear.

[0004] Therefore, the present invention proposes a device for testing the wrinkle resistance of down jacket fabrics to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a device for testing the wrinkle resistance of down jacket fabrics to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A device for testing the wrinkle resistance of down jacket fabric includes a base and a mounting plate. The base has a concave cavity containing a parallel light source. The mounting plate is positioned opposite the concave cavity and has evenly distributed photosensitive probes for receiving light emitted from the parallel light source. The device also includes a suspension assembly for suspending the test fabric between the concave cavity and the mounting plate, and a wrinkling assembly for creating regional wrinkles in the test fabric. After the test fabric is wrinkled by the wrinkling assembly and allowed to recover for a certain period, the wrinkle resistance of the test fabric is evaluated by the difference in the number of photosensitive probes receiving light from the parallel light source before and after the wrinkle formation. The wrinkle resistance of the test fabric is positively correlated with this difference.

[0007] In one alternative embodiment: the suspension assembly includes a slot on a base component and two base blocks that can be slidably engaged in the slot. The slot is located above the concave cavity. Each of the two base blocks is provided with a front extension rod. Each of the two front extension rods is provided with a clamp for holding the fabric. The slot wall is provided with a magnetic strip. The base blocks are made of iron material.

[0008] In one alternative: the mounting plate is movable to be misaligned with the concave cavity; the base component has a horizontally oriented strip frame; a slidable support seat is fitted into the strip frame; the mounting plate is mounted on the support seat; a through groove is provided on one side of the strip frame; a column adapted to the through groove is provided on the support seat; the end of the column away from the support seat passes through the through groove; and a positioning sleeve is threaded onto the column segment outside the strip frame.

[0009] In one alternative: the wrinkling assembly is liftable, the wrinkling assembly includes a support platform and a soft rubber tube disposed on the support platform, the support platform is provided with a rotatable annular component, the annular component is symmetrically provided with two telescopic components, the telescopic ends of the two telescopic components are provided with pressure plates, and a pressure sensor is provided between the telescopic ends of the telescopic components and the pressure plates. The bottom side of the annular component is provided with a gear ring, and the bottom side of the support platform is provided with a gear that meshes with the gear ring and a drive component for driving the gear to rotate.

[0010] In one alternative: the base component is provided with a telescopic support rod for raising and lowering the wrinkling assembly. The telescopic support rod includes a square cylinder, a first sealing piston disposed in the square cylinder, and a vertical rod disposed on the first sealing piston. The upper end of the vertical rod is fixedly connected to the support platform.

[0011] In one alternative embodiment: the strip frame is provided with an inflation component for inflating the square cylinder. The inflation component includes an air cylinder, a second sealing piston disposed in the air cylinder, and a push rod disposed on the second sealing piston. The end of the push rod away from the second sealing piston is located outside the air cylinder. An air guide pipe is provided between the air cylinder and the square cylinder. During the movement of the misaligned concave cavity of the mounting plate, the bearing seat abuts against the end of the push rod away from the second sealing piston, thereby pushing the second sealing piston to move towards the bottom of the air cylinder, realizing the injection of air into the square cylinder to drive the wrinkling assembly to rise. When the misaligned concave cavity of the mounting plate moves into place, the wrinkling assembly moves up into place.

[0012] In one alternative: the opening of the concave cavity is provided with a transparent plate.

[0013] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows: First, the test fabric is suspended between the concave cavity and the mounting plate using a suspension assembly, ensuring the upper edge of the fabric is straight. Then, a wrinkling assembly is used to create regional wrinkles in the fabric. Next, a parallel light source is turned on, and the number of light sensors that can receive light normally at this moment is recorded as the initial number. After a certain period of time, the number of light sensors that can receive light normally at this moment is recorded again as the timed recovery number. The wrinkle resistance of the test fabric is evaluated by the difference between the initial number and the timed recovery number. The wrinkle resistance of the test fabric is positively correlated with this difference: the larger the difference, the higher the recovery rate of the test fabric per unit time, i.e., the better the wrinkle resistance; conversely, the smaller the difference, the worse the wrinkle resistance. This simulates the regional wrinkling of the fabric under the actual wearing scenario of a down jacket, thus intuitively and accurately reflecting the wrinkle resistance of the test fabric under actual wearing conditions.

Detailed Implementation

[0025] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Please see Figures 1-3 A device for testing the wrinkle resistance of down jacket fabric includes a base component 1 and a mounting plate 6. The base component 1 has a concave cavity 2, and a parallel light source 3 is provided in the concave cavity 2. The mounting plate 6 is arranged opposite to the concave cavity 2. Photosensitive probes 10 are evenly distributed on the mounting plate 6 to receive the light emitted by the parallel light source 3. The testing device also includes a suspension component 5 for suspending the test fabric between the concave cavity 2 and the mounting plate 6, and a wrinkling component 11 for creating regional wrinkles in the test fabric. After the test fabric is wrinkled by the wrinkling component 11 and recovers for a certain period of time, the wrinkle resistance of the test fabric is evaluated by the difference in the number of photosensitive probes 10 that receive the light emitted by the parallel light source 3 before and after the wrinkle formation. The wrinkle resistance of the test fabric is positively correlated with this difference.

[0027] First, the test fabric is suspended between the concave cavity 2 and the mounting plate 6 using the suspension assembly 5, ensuring the upper edge of the fabric is straight. Then, the wrinkling assembly 11 causes regional wrinkles in the fabric. Next, the parallel light source 3 is turned on. Due to the light-blocking effect of the test fabric, only a portion of the photosensitive probes 10 can normally receive the light emitted by the parallel light source 3. The number of photosensitive probes 10 that can normally receive the light at this moment is recorded (automatically counted and fed back by the corresponding system; this system is not shown in the diagram, is existing technology, and does not present any technical obstacles, so it will not be elaborated here). This number is recorded as the initial number. After a certain period of time... (For fabric self-recovery), record the number of light sensors 10 that can receive light normally at this moment, and record it as the timed recovery number. The wrinkle resistance of the test fabric is evaluated by the difference between the initial number and the timed recovery number. The wrinkle resistance of the test fabric is positively correlated with this difference. Specifically, the larger the difference, the higher the recovery rate of the test fabric per unit time (when the fabric recovers, its unfolded area continuously increases, thus blocking more light sensors 10), that is, the better the wrinkle resistance. Conversely, the wrinkle resistance is worse. This simulates the regional wrinkling of the fabric in the actual wearing scenario of a down jacket, so as to intuitively and accurately reflect the wrinkle resistance of the test fabric when it is actually worn.

[0028] Furthermore, the opening of the concave cavity 2 is provided with a transparent plate 4, which serves to protect the parallel light source 3.

[0029] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the suspension assembly 5 includes a slot 501 disposed on the base component 1 and two base blocks 502 slidably disposed in the slot 501. The slot 501 is located above the concave cavity 2. Each of the two base blocks 502 is provided with a front extension rod 505. Each of the two front extension rods 505 is provided with a clamp 504 for clamping the fabric. The slot 501 has a magnetic strip 503 on its groove wall. The base blocks 502 are made of iron material.

[0030] In this embodiment, two clamps 504 respectively hold the two ends of the upper edge of the test fabric, and then push the front extension rod 505 to make the two base blocks 502 move away from each other until the upper edge of the test fabric is straightened. Since the base blocks 502 are made of iron material, the magnetic strip 503 can be used to position the base blocks 502 (a certain external force needs to be applied to slide), which can slide and stop at the same time, making the suspension assembly 5 convenient and quick to operate.

[0031] Please see Figure 1 , Figure 2 and Figure 4In one embodiment of the present invention, the mounting plate 6 is movable to be misaligned with the concave cavity 2. The base component 1 is provided with a horizontally oriented strip frame 7. A slidable support seat 13 is fitted in the strip frame 7. The mounting plate 6 is disposed on the support seat 13. A through groove 15 is provided on one side of the strip frame 7. A column 14 adapted to the through groove 15 is provided on the support seat 13. The end of the column 14 away from the support seat 13 passes through the through groove 15. A positioning sleeve 16 is threadedly fitted on the column section of the column 14 located outside the strip frame 7.

[0032] In this embodiment, when the mounting plate 6 needs to be moved, first loosen the positioning sleeve 16, then hold the positioning sleeve 16 to make the bearing seat 13 slide along the strip frame 7, thereby moving the mounting plate 6. After it is moved into place, tighten the positioning sleeve 16 to position the mounting plate 6. The purpose of making the mounting plate 6 movable is to move the mounting plate 6 to misalign it with the concave cavity 2 when suspending the test fabric, so as to avoid the mounting plate 6 blocking the front of the concave cavity 2 (i.e., to prevent it from blocking the front of the concave cavity 2). Figure 1 , Figure 2 (The angle shown is explained) The interference affects the suspension operation of the test fabric. After the test fabric is suspended, the mounting plate 6 is moved to face the concave cavity 2.

[0033] Please see Figure 5 and Figure 6 In one embodiment of the present invention, the wrinkling component 11 is liftable. The wrinkling component 11 includes a support platform 1101 and a soft rubber tube 1102 disposed on the support platform 1101. The support platform 1101 is provided with a rotatable annular component 1104. Two telescopic components 1105 are symmetrically provided on the annular component 1104 (the telescopic component 1105 is a telescopic cylinder, electric telescopic rod, etc. in the prior art, which will not be limited or described in detail here). The telescopic ends of the two telescopic components 1105 are provided with pressure plates 1103, and a pressure sensor 1106 is provided between the telescopic ends of the telescopic components 1105 and the pressure plates 1103. The bottom side of the annular component 1104 is provided with a gear ring 1107, and the bottom side of the support platform 1101 is provided with a gear that meshes with the gear ring 1107 and a drive component 1108 for driving the gear to rotate (the drive component 1108 is a rotating device such as a servo motor or a geared motor in the prior art, which is not limited or described in detail here).

[0034] In this embodiment, after the test fabric is suspended, the lower part of the test fabric is crumpled into a ball and placed in the soft rubber tube 1102. Then, two telescopic members 1105 extend synchronously, driving two pressure plates 1103 to press the soft rubber tube 1102, thereby causing wrinkles in the test fabric. The pressure sensor 1106 monitors the compressive force. When the pressure plates 1103 press the soft rubber tube 1102 to the set force, the two telescopic members 1105 stop extending, maintaining the current pressing state for a certain period of time. Then, the two telescopic members 1105 retract and return to their original position. The two pressure plates 1103 are reset, and then the ring part 1104 is driven to rotate by the driving component 1108, thereby causing the two pressure plates 1103 to revolve to adjust the pressing direction. After the adjustment is in place, the above pressing action is repeated. By changing the pressing direction multiple times, the test fabric will produce regional rich wrinkles. It should be noted that the adjustment of the pressing direction and the number of times are randomly controlled by the operator. The purpose is to make the test fabric produce random and rich wrinkles, so as to accurately reflect the wrinkle resistance performance of the test fabric under regional wrinkle conditions in subsequent tests.

[0035] Please see Figure 1 , Figure 7 and Figure 8 In one embodiment of the present invention, the base component 1 is provided with a telescopic support rod 9 for realizing the lifting and lowering of the wrinkling component 11. The telescopic support rod 9 includes a square cylinder 901, a first sealing piston 902 disposed in the square cylinder 901, and a vertical rod 903 disposed on the first sealing piston 902. The upper end of the vertical rod 903 is fixedly connected to the support platform 1101. The strip frame 7 is provided with an inflation component 12 for inflating the square cylinder 901. The inflation component 12 includes an air cylinder 1201, a second sealing piston 1202 disposed in the air cylinder 1201, and a push rod 1203 disposed on the second sealing piston 1202. One end of the push rod 1203 away from the second sealing piston 1202 is located outside the air cylinder 1201. An air guide pipe 8 is provided between the air cylinder 1201 and the square cylinder 901. During the movement of the misaligned concave cavity 2 of the mounting plate 6, the bearing seat 13 abuts against the end of the push rod 1203 away from the second sealing piston 1202, thereby pushing the second sealing piston 1202 to move toward the bottom of the air cylinder 1201, realizing the injection of air into the square cylinder 901 to drive the wrinkling component 11 to rise. When the misaligned concave cavity 2 of the mounting plate 6 moves into place, the wrinkling component 11 moves up into place.

[0036] In this embodiment, when suspending the test fabric, the wrinkling component 11 is located directly in front of the concave cavity 2 (within the center of the cavity). Figure 1(The angle shown is used for explanation). The mounting plate 6 is misaligned with the concave cavity 2. At this time, the end of the push rod 1203 away from the second sealing piston 1202 abuts against the support seat 13, and the second sealing piston 1202 is at the bottom of the air cylinder 1201. The first sealing piston 902 is at the top of the square cylinder 901 under air pressure. After the test fabric is suspended and regional wrinkles are generated on the test fabric through the wrinkling component 11, the mounting plate 6 is moved to a position opposite to the concave cavity 2. The support seat 13 is no longer away from the push rod 1203 and the second sealing piston 1202. When one end of the cylinder 2 is against the other, the air pressure support inside the square cylinder 901 is lost. The first sealing piston 902 moves down under the gravity of the wrinkling assembly 11, thereby injecting air into the air cylinder 1201. The second sealing piston 1202 moves the push rod 1203 towards the support seat 13 under the push of air pressure, thus completing the position switch between the wrinkling assembly 11 and the mounting plate 6. Conversely, the support seat 13 pushes the push rod 1203 against the second sealing piston 1202 towards the bottom of the air cylinder 1201, injecting air into the square cylinder 901 and thus causing the wrinkling assembly 11 to rise.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
