Technical Field

[0001] This utility model belongs to the technical field of fabric testing equipment, specifically relating to a fabric color fastness to perspiration testing device. Background Technology

[0002] The colorfastness tester for perspiration is used to assess the colorfastness of textiles to perspiration, water, and seawater; it can also be used for yellowing tests, meeting US and European standards. It can determine the colorfastness of textiles to water and perspiration.

[0003] Color fastness to perspiration is a test used to assess the color fastness of various colored textiles to perspiration, water, and seawater. The current testing procedure for color fastness to perspiration often involves immersing the fabric to be tested in a prepared solution, then removing it, squeezing out the water, drying it, and finally analyzing it using a testing instrument. People tend to sweat more easily in areas such as underarms, and the fabric in these areas is often repeatedly rubbed. However, the traditional soaking method cannot simulate the actual effect of the clothing under these conditions. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a device for testing the color fastness of fabrics to perspiration stains.

[0006] The friction structure includes a fixed block fixedly connected to the rear end of the device cylinder. The front end surface of the fixed block has multiple sliding grooves opened laterally. Each of the multiple sliding grooves is laterally slidably connected to a sliding rod. The front end of each of the multiple sliding rods is fixedly connected to a fixed friction block. Multiple springs are laterally fixedly connected between the fixed friction block and the fixed block.

[0010] Preferably, a cap is detachably mounted on the top of the device cylinder.

[0011] Preferably, a reinforcing rib is fixedly connected between the upper surface of the base and the front surface of the upright plate.

[0012] The beneficial effects of this invention are as follows: By setting a fixed friction block and a movable friction block, the fabric to be tested is placed between the fixed friction block and the movable friction block during actual use.

[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] Example: A device for testing the colorfastness of fabrics to perspiration, such as... Figures 1-3 As shown, it includes a base 1, a vertical plate 2 is fixedly connected to the rear end of the upper surface of the base 1, a connecting frame 3 is fixedly connected to the upper part of the front side surface of the vertical plate 2, and a device cylinder 4 with an open top is fixedly connected to the inside of the connecting frame 3. A friction structure is provided inside the device cylinder 4.

[0019] The friction structure includes a fixed block 12 fixedly connected to the rear end of the device cylinder 4. The front surface of the fixed block 12 is provided with multiple sliding grooves in the horizontal direction. The sliding rods 13 are slidably connected to the interior of each sliding groove in the horizontal direction. The front ends of the sliding rods 13 are fixedly connected to a fixed friction block 14. Multiple springs 15 are fixedly connected to the fixed friction block 14 and the fixed block 12 in the horizontal direction. A movable friction block 11 that can move vertically back and forth is provided inside the device cylinder 4 and in front of the fixed friction block 14.

[0020] When the multiple springs 15 are not under force, the fixed friction block 14 and the movable friction block 11 are in contact with each other.

[0021] A cap 5 is detachably mounted on the top of the device cylinder 4.

[0022] When using the device, the fixed friction block 14 is pushed backward, creating a certain gap between its front end and the movable friction block 11. The fabric to be tested is then fed between them. Next, the fixed friction block 14 is released, and under the action of multiple springs 15, the fixed friction block 14 is pushed forward, with its front end adhering to the rear end surface of the movable friction block 11. The fabric between them is then clamped. At this time, the prepared solution is poured into the device cylinder 4. After pouring, the cap 5 is installed on the top of the device cylinder 4. Then, the device is started, and the movable friction block 11 will reciprocate vertically to simulate the effect of the fabric being worn on the human body, making the final test results more reliable.

[0023] A support base 6 is fixedly connected to the upper surface of the base 1. A motor 7 is fixedly connected to the upper surface of the support base 6 laterally. A rotating disk 8 is fixedly connected to the outer end of the output shaft of the motor 7. An eccentrically set connecting block is fixedly connected to the rear surface of the rotating disk 8. A sliding hole is vertically opened through the bottom end of the device cylinder 4. A sliding shaft 10 is vertically slidably connected inside the sliding hole. A connecting rod 9 is hinged between the bottom end of the sliding shaft 10 and the connecting block.

[0024] The movable friction block 11 is fixedly connected to the top of the sliding shaft 10.

[0025] When the motor 7 is running, its output shaft drives the rotating disk 8 to rotate. The connecting block on the back of the rotating disk 8 performs circular motion, which drives one end of the connecting rod 9 to perform synchronous circular motion. The other end of the connecting rod 9 will drive the sliding shaft 10 to move. Since the sliding shaft 10 is limited by the sliding hole and can only move vertically, the sliding shaft 10 will perform reciprocating vertical motion, thereby driving the movable friction block 11 to perform synchronous vertical reciprocating motion.

[0026] A rubber sealing ring is installed inside the sliding hole at the bottom of the device cylinder 4. It does not affect the normal movement of the sliding shaft 10, and can also play a sealing role to prevent liquid leakage.

[0027] A reinforcing rib 16 is fixedly connected between the upper surface of the base 1 and the front surface of the upright plate 2.

[0028] The reinforcing rib 16 improves the stability of the connection between the base 1 and the upright plate 2, thus improving the overall stability of the device.

[0029] The principle of this invention is as follows: When using the device, the fixed friction block 14 is pushed backward, creating a certain gap between its front end and the movable friction block 11. The fabric to be tested is then fed between them. Next, the fixed friction block 14 is released, and under the action of multiple springs 15, it is pushed forward, with its front end adhering to the rear end surface of the movable friction block 11. The fabric between them is then clamped. At this time, the prepared solution is poured into the device cylinder 4. After pouring, the cap 5 is installed on the top of the device cylinder 4. Then, the device is started. Driven by the motor 7, the rotating disk 8 begins to rotate, and the connecting block on its rear side performs a circular motion, driving one end of the connecting rod 9 to perform a synchronous circular motion. The sliding shaft 10 then performs a reciprocating vertical motion, thereby driving the movable friction block 11 to perform a synchronous vertical reciprocating motion. This simulates the effect of the fabric being worn on the human body, making the final test results more reliable.

[0030] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
