Description

Technical Field

[0001] The utility model relates to the technical field of textile friction color fastness testing, in particular to a textile friction color fastness tester. Background Art

[0002] The rubbing color fastness test is a test method to evaluate the color retention ability of textiles by simulating the friction that may occur during normal use. This test can help manufacturers and consumers understand the color retention performance of textiles under different conditions, thereby ensuring product quality and safety. When conducting friction tests on textiles, the rotation method test and the curved surface method test are generally used;

[0003] Among them, the rotation method test is a method suitable for testing the color fastness to friction of textiles with small printing and dyeing areas or testing small areas. This method rubs the sample by rotating the friction head to simulate the friction effect during actual use, thereby evaluating the color retention ability. Compared with the linear method, the rotation method can not only test on a smaller sample size, but also more accurately reflect the degree of staining of a small local friction area;

[0004] The curved surface method test mainly simulates the friction that may occur to textiles when worn by the human body. The textiles are rubbed with a friction head of a specific shape and material to evaluate their color retention performance when worn by the human body. This method is particularly suitable for evaluating textiles that are worn close to the body.

[0005] Although the existing technology can test the color fastness of textiles by rubbing them, some consumers believe that seeing is believing. Therefore, in the sales process, some staff can allow consumers to observe the color fastness of textiles more intuitively through on-site friction tests, so as to observe the dyeing quality of textiles. However, the textile friction color fastness tester in the existing technology is large in size and the test is cumbersome, which is not convenient for intuitive display to consumers.

[0013] In a preferred example, the utility model can be further configured as follows: a number of circular holes are opened on the bottom side of the positioning ring, and anti-slip rubber blocks are fixedly connected in the circular holes.

[0014] In summary, the present invention includes at least one of the following beneficial technical effects:

[0015] 1. When displaying the textile color fastness to friction tester to consumers, the textile can be directly placed on the top side of the base, and then the electric telescopic joint is started to drive the counterweight column to descend, so that the friction head is finally fitted with the textile, and the counterweight column is rotated by the cooperation of the slider and the spiral groove, and finally the rotational friction is performed to test the textile color fastness to friction, so that consumers can observe the color fastness quality of the textile more intuitively.

[0016] 2. In the textile friction color fastness tester, when the pressure rotating part is started, the electric telescopic joint is started to extend downward, and the counterweight column will drop due to gravity.

[0017] 3. In the textile friction color fastness tester, the limiting plate will follow the weight column to descend, and the positioning plate will move with the extension of the electric telescopic joint. Therefore, after the weight column drives the friction head to fit the textile, the positioning plate will continue to descend, and the downward pressure spring will be compressed, thereby applying pressure to the weight column. At this time, the positioning piece will be subjected to the pressure drop to achieve the effect of positioning the textile;

[0018] 4. In this textile friction color fastness tester, when the counterweight column descends, the swivel ring connected to the bottom side of the outer peripheral wall of the counterweight column will be driven to descend, and then the locating ring will be driven to descend through the connecting block and the positioning rod. The locating ring will slide downward through the cooperation of the sliding rod and the sliding groove, wherein the cooperation of the sliding rod and the sliding groove prevents the locating ring from rotating with the counterweight column. When the locating ring descends to fit the textile, the anti-slip rubber block at the bottom will fit the textile and increase the pressure as the electric telescopic joint descends, so that the counterweight column can better position the friction head when it drives it to rotate, avoiding wrinkles on the product that affect the friction of the friction head.

Specific embodiments

[0025] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Embodiment:

[0027] Referring to Figure 1-Figure 4 , a friction color fastness tester for textiles disclosed by the present utility model includes a base 1 and a bracket 2. The bracket 2 is arranged in a U shape, and the end of the bracket 2 is fixedly connected to the bottom side of the outer peripheral wall of the base 1. A support tube 3 is fixedly connected to the top side of the bracket 2, and the bottom end of the support tube 3 extends below the top side of the bracket 2. A counterweight column 5 is connected in the support tube 3 through a pressure screw member 4. The counterweight column 5 is hollow, and a friction head 6 is fixedly connected to the bottom end of the counterweight column 5. A positioning member 7 is arranged on the bottom side of the outer peripheral wall of the counterweight column 5.

[0028] In this embodiment, the textile is placed on the top side of the base 1 and flattened, and then the pressing and rotating part 4 is started to descend, and the counterweight column 5 will follow the pressing and rotating part 4 to descend due to gravity. When the friction head 6 set at the bottom of the counterweight column 5 is in contact with the textile, the positioning part 7 will synchronously fit with the textile. Then, the continuous downward pressure of the pressing and rotating part 4 will drive the counterweight column 5 to rotate, and at the same time, pressure will be applied to the counterweight column 5. The positioning part 7 will increase the pressure and fit the textile to achieve the positioning effect, and the counterweight column 5 will drive the friction head 6 to rotate and rub the textile, thereby achieving the friction effect. After the friction is completed, the pressing and rotating part 4 is recovered, and the color fastness can be intuitively observed by directly comparing the rubbed position of the textile with the surrounding position, thereby facilitating consumers to intuitively observe the dyeing quality of the textile.

[0029] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the pressing and rotating part 4 includes an electric telescopic joint 8, which is fixedly installed at the top of the support tube 3. The output end of the electric telescopic joint 8 extends into the support tube 3. A spiral groove 21 is opened on the inner wall of the counterweight column 5. The upper and lower ends of the spiral groove 21 are both closed. A slider 9 matching the spiral groove 21 is installed on the side of the output end of the electric telescopic joint 8, and the slider 9 is slidably connected to the spiral groove 21.

[0030] In this embodiment, when the pressure-rotating part 4 is started, the electric telescopic joint 8 is started to extend downward, and the counterweight column 5 will drop due to gravity. Then, when the counterweight column 5 drives the friction head 6 to fit the textile, the slider 9 will drop along the spiral groove 21. However, the slider 9 is fixedly mounted on the bottom end of the outer peripheral wall of the electric telescopic joint 8, and the counterweight column 5 with the spiral groove 21 is rotatably mounted on the outer peripheral wall of the output end of the electric telescopic joint 8, and can slide up and down. Then, when the slider 9 drops, the counterweight column 5 will rotate due to the friction between the spiral groove 21 and the slider 9, thereby achieving the effect of allowing the friction head 6 to rotate and rub the textile.

[0031] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the top side of the counterweight column 5 is rotatably connected to a limiting plate 10, and the limiting plate 10 is slidably connected to the output end of the electric telescopic joint 8. A positioning plate 11 is arranged above the limiting plate 10, and the positioning plate 11 is fixedly connected to the output end of the electric telescopic joint 8. A downward pressure spring 12 is connected between the positioning plate 11 and the limiting plate 10.

[0032] In this embodiment, the limiting plate 10 will descend along with the counterweight column 5, and the positioning plate 11 will move along with the extension of the electric telescopic joint 8. Therefore, after the counterweight column 5 drives the friction head 6 to fit the textile, the positioning plate 11 will continue to descend, and the downward pressure spring 12 will be compressed, thereby applying pressure to the counterweight column 5. At this time, the positioning piece 7 will be subjected to the pressure drop to achieve the effect of positioning the textile.

[0033] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the positioning member 7 includes a swivel 13, which is rotatably mounted on the bottom side of the outer peripheral wall of the counterweight column 5. The outer peripheral wall of the swivel 13 is symmetrically connected to two connecting blocks 14 with the axis of the swivel 13 as a reference. A positioning rod 15 is fixedly connected to the two connecting blocks 14 on the side away from the swivel 13. A positioning ring 16 is sleeved between the ends of the two positioning rods 15. Two sliding rods 17 are connected to the outer peripheral wall of the positioning ring 16. Sliding grooves 18 are opened on both sides of the inner side of the bracket 2. The two sliding rods 17 are slidably connected to the two sliding grooves 18 respectively. A number of circular holes 19 are opened on the bottom side of the positioning ring 16. An anti-slip rubber block 20 is fixedly connected in the circular hole 19.

[0034] In this embodiment, when the counterweight column 5 descends, the swivel 13 rotatably connected to the bottom side of the outer peripheral wall of the counterweight column 5 will be driven to descend, and then the locating ring 16 will be driven to descend through the connecting block 14 and the positioning rod 15. The positioning ring 16 will slide downward through the cooperation of the slide rod 17 and the slide groove, wherein the cooperation of the slide rod 17 and the slide groove prevents the positioning ring 16 from rotating with the counterweight column 5 when the counterweight column 5 rotates. When the positioning ring 16 descends to fit the textile, the anti-slip rubber block 20 at the bottom will fit the textile and increase the pressure as the electric telescopic joint 8 descends, so that the counterweight column 5 can drive the friction head 6 to rotate better. Positioning can be avoided to prevent wrinkles on the product that affect the friction of the friction head 6.

[0035] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
