[0002] Color fastness refers to the degree of fading of dyed fabrics under the influence of external factors (extrusion, friction, washing, rain, exposure, light, seawater immersion, saliva immersion, water stains, sweat stains, etc.) during use or processing. It is an important indicator of fabrics. In the field of textile quality control, color fastness is a core indicator to measure the durability and appearance retention of fabrics. Its accurate detection is crucial to ensuring the quality of textiles.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 5 In an embodiment of the utility model, a multi-directional friction color fastness detection device for clothing fabrics comprises a rotating cylinder 10, a base 21, a fabric fixing mechanism 40 and a detection mechanism 50. The fabric fixing mechanism 40 is fixed with the fabric to be tested. In this embodiment, the color fastness of the fabric is detected by a friction test; the rotating cylinder 10 is rotatably mounted on the base 21, and a plurality of the fabric fixing mechanisms 40 are arranged on the rotating cylinder 10. The fabric fixing mechanisms 40 are slidably mounted on the inner wall of the rotating cylinder 10. It should be noted that the fabric fixing mechanisms 40 slide up and down along the vertical direction on the inner wall of the rotating cylinder 10; the detection mechanism 50 is mounted on the base 21, and the detection mechanism 50 comprises a rotating shaft 51, a connecting frame 52 and a friction The friction device 53 comprises a rotating shaft 51 which is rotatably mounted on the base 21, and the rotation direction of the rotating shaft 51 is opposite to the rotation direction of the rotating cylinder 10, and the rotation angle of the rotating shaft 51 is 0-60°; when the rotating shaft 51 and the rotating cylinder 10 rotate, the friction device 53 contacts the fabric fixed on the fabric fixing mechanism 40 to perform friction detection on the color fastness of the fabric. Since the rotation direction of the rotating shaft 51 is opposite to the rotation direction of the rotating cylinder 10, and the fabric fixing mechanism 40 can slide up and down along the inner wall of the rotating cylinder 10, during the detection process, when the rotating shaft 51 rotates, the friction device 53 performs friction test on the fabric in the horizontal direction and the inclined direction; when the rotating shaft 51 is stationary, the friction device 53 performs friction test on the fabric in the vertical direction.

[0021] In the embodiment of the present application, a first gear 511 is fixedly mounted on the rotating shaft 51, a second gear 22 is rotatably mounted on the bottom of the base 21, a ring gear 11 is fixedly mounted on the bottom of the rotating cylinder 10, and the second gear 22 is meshed with the first gear 511 and the ring gear 11. It can be understood that when the rotating shaft 51 rotates, the first gear 511 drives the ring gear 11 to rotate through the second gear 22, thereby driving the rotating cylinder 10 to rotate on the base 21, and during the rotation process, the rotation direction of the rotating cylinder 10 is opposite to the rotation direction of the rotating shaft 51.

[0022] Furthermore, in the embodiment of the present application, a bottom protective cover 20 is also provided below the base 21, and the bottom protective cover 20 is detachably connected to the base 21, and a rotating motor for driving the rotating shaft 51 to rotate is installed inside the bottom protective cover 20. It should be noted that the rotating motor is a forward and reverse motor, and the rotating motor controls the rotating shaft 51 to intermittently change the direction, so that the rotating shaft 51 rotates in a clockwise and counterclockwise manner, and in the present embodiment, the rotation angles of the rotating shaft 51 when rotating clockwise and counterclockwise are both 0-60°.

[0023] In the embodiment of the present application, it also includes a lifting and adjusting mechanism 30 for controlling the up and down sliding of the fabric fixing mechanism 40. The lifting and adjusting mechanism 30 includes an adjusting screw 31 rotatably installed on the outside of the rotating cylinder 10 and an adjusting screw sleeve 32 threadedly connected to the adjusting screw 31, and the adjusting screw sleeve 32 is fixedly connected to the fabric fixing mechanism 40; the rotating cylinder 10 is also equipped with a driving motor 33 for driving the adjusting screw 31 to rotate. When the driving motor 33 controls the rotation of the adjusting screw 31, the adjusting screw 31 drives the fabric fixing mechanism 40 to move up and down through the adjusting screw sleeve 32, thereby changing the contact trajectory (friction direction) of the friction device 53 and the fabric during the friction test. In this embodiment, the driving motor 33 can adopt a variable frequency motor. By changing the rotation speed of the driving motor 33, the up and down moving speed of the fabric fixing mechanism 40 can be controlled, and the contact trajectory of the friction device 53 and the fabric can be further changed, so that the friction device 53 can contact the fabric in different directions, thereby improving the friction test effect of the fabric.

[0024] It should be noted that the fabric fixing mechanism 40 can use the fabric fixing component on the color fastness detection device in the prior art. In this embodiment, the fabric fixing mechanism 40 includes a fabric fixing plate 41 and two fixers 42 arranged on the sides of the fabric fixing plate 41, and the fixers 42 are used to squeeze and fix the two sides of the fabric.

[0025] See also Figure 5In this embodiment, the friction device 53 includes a shell 531, a movable frame 533 and a friction head 537. A partition 532 is fixedly installed inside the shell 531. The partition 532 divides the internal space of the shell 531 into a first cavity and a second cavity. A guide rod 536 is fixedly installed inside the first cavity. The movable frame 533 is slidably connected with the guide rod 536, and one side of the movable frame 533 is fixedly connected with the friction head 537. An insertion port is opened on the other side of the movable frame 533. A telescopic rod 538 is fixedly installed inside the second cavity. The telescopic end of the telescopic rod 538 is connected with a pull plate 534 after passing through the insertion port. The size of the pull plate 534 is larger than the size of the insertion port. The movable frame 533 is also connected to the partition 532 through a tensioning spring 535. During the fabric friction test, the tension of the tensioning spring 535 can be changed by adjusting the length of the telescopic rod 538, so that the friction force applied by the friction head to the fabric when it contacts the fabric can be adjusted, thereby improving the friction test effect.
