The reciprocating movement structure 6 is installed on the right side of the machine base 1. The swing arm 3 is installed on the moving end of the reciprocating movement structure 6. The rubbing head 2 is installed on the swing arm 3. The reciprocating movement structure 6 drives the swing arm 3 to move left and right so that the rubbing head 2 rubs the surface of the textile on the rubbing table 11. The lifting structure 5 is installed on the machine base 1 and is located between the rubbing table 11 and the reciprocating movement structure 6. Its lifting end is connected to the middle of the swing arm 3 and drives the swing arm 3 to move up and down. During operation, the lifting structure 5 lifts the swing arm 3, places the textile on the rubbing table 11 and fixes it by the fixing structure 4. The lifting structure 5 lowers the swing arm 3. The reciprocating movement structure 6 drives the swing arm 3 to move left and right, so that the rubbing table 2 performs a reciprocating rubbing test on the surface of the textile. The rubbing color fastness detector of this embodiment uses the lifting structure to raise or lower the swing arm, which is convenient for the rubbing head to perform a rubbing test on the surface of the textile on the rubbing table and replace the textile, reduces manual operation, and effectively improves work efficiency.

[0023] In this embodiment, the lifting structure 5 includes a stepper motor 51, a push rod 52, and a lifting block 53. The stepper motor 51 is installed on the machine base 1 and is located between the friction table 11 and the reciprocating movement structure 6, with its output end facing upward. The push rod 52 is vertically installed on the output end of the stepper motor 51, and the lifting block 53 is installed on the top of the push rod 52. The swing arm 3 is placed on the top of the lifting block 53. When the stepper motor 51 rotates, it drives the push rod 52 to move up and down, causing the lifting block 53 to move up and down, and automatically lifting or lowering the swing arm 3. A through groove 31 vertically penetrating the swing arm 3 is provided in the middle of the swing arm 3. A limit block 54 is provided on the top of the lifting block 53, and the limit block 54 extends into the through groove 31. The swing arm 3 moves left and right on the top of the lifting block 53.
