[0002] The wear resistance test of textile fabrics is an important part of evaluating fabric quality. During the test, the fabrics are subjected to mechanical friction to simulate the wear and tear that may be encountered in daily use.

[0046] A controller 10 is installed on the mounting frame 1, and the controller 10 includes a friction control system. The friction control system includes a control module, and the input end of the control module is respectively connected to a first speed monitoring module, a second speed monitoring module and a contact pressure monitoring module, the input end of the first speed monitoring module is connected to the first photoelectric encoder 203, the input end of the second speed monitoring module is connected to the second photoelectric encoder, and the input end of the contact pressure monitoring module is connected to the pressure sensor 9; the output end of the control module is respectively connected to a contact pressure regulating module, a friction speed regulating module and a contact pressure self-regulating module, and the output ends of the contact pressure regulating module, the friction speed regulating module and the contact pressure self-regulating module are all connected to the first motor 202 and the second motor; a touch display panel is provided at the front end of the controller 10.

[0047] See also Figure 7-10 , a method for using a textile fabric wear resistance testing device comprises the following steps:

[0048] Step 1: fix the two ends of the fabric body 11 on the first winding assembly 2 and the second winding assembly 3 respectively, and input the contact pressure value and the friction speed value during friction through the touch display panel of the controller 10;

[0049] Step 2: The controller 10 starts the first motor 202 and the second motor, and the first motor 202 and the second motor rotate in opposite directions, so that the fabric body 11 is gradually tightened from the drooping state and pushes the friction roller 4 to move upward, and the friction roller 4 pushes the lifting rod 6 to move upward through the roller frame 5, and the lifting rod 6 squeezes the pressure sensor 9 through the coil spring 8 until the contact pressure between the friction roller 4 and the fabric body 11 reaches the set contact pressure value;

[0050] Specifically, the fabric body 11 is rolled up by the reverse rotation of the first winding roller 201 and the second winding roller, and then the fabric body 11 is lifted, so that the fabric body 11 gradually tightens and rises to press the pressure sensor 9 to reach a set contact pressure value;

[0051] Step 3: When the contact pressure reaches the set contact pressure value, the controller 10 controls the first motor 202 and the second motor so that the first motor 202 and the second motor reciprocate in the same direction, and the rotation speed of the reciprocating movement in the same direction is equal to the set friction speed value, and the friction operation is performed;

[0052] Specifically, the first winding roller 201 and the second winding roller reciprocate in the same direction to realize the winding movement of the fabric body 11 between the first winding roller 201 and the second winding roller, so that the fabric body 11 passes through the friction roller 4 at a stable linear speed and rubs against it at a constant speed, and at the same time, the unwound length of the fabric body 11 is kept consistent, thereby ensuring that the contact pressure remains unchanged;

[0053] Step four, friction is performed under the set friction speed conditions, and the pressure sensor 9 monitors the contact pressure in real time. When the real-time contact pressure is less than the set contact pressure value, the controller 10 controls one of the first motor 202 and the second motor to accelerate the rotation until the real-time contact pressure is equal to the set contact pressure value, and then makes one of the accelerated motors return to the set friction speed value again; when the real-time contact pressure is greater than the set contact pressure value, the controller 10 controls one of the first motor 202 and the second motor to decelerate the rotation until the real-time contact pressure is equal to the set contact pressure value, and then makes one of the decelerated motors return to the set friction speed value again, thereby realizing automatic adjustment of the friction contact pressure.

[0054] Specifically, when the real-time contact pressure value is less than the set contact pressure value, it means that the unwound length of the fabric body 11 is too large. By accelerating one of the motors, the unwound length of the fabric body 11 is reduced, and then the real-time contact pressure value is increased to reach the set contact pressure value, and then the set friction speed value is restored; when the real-time contact pressure value is greater than the set contact pressure value, it means that the unwound length of the fabric body 11 is too small. By decelerating one of the motors, the unwound length of the fabric body 11 is increased, and then the real-time contact pressure value is reduced to reach the set contact pressure value, and then the set friction speed value is restored.

[0055] Compared with the traditional fabric wear resistance detection equipment, the present invention rewinds the fabric body 11 and squeezes the friction roller 4 by the reverse rotation of the first winding component 2 and the second winding component 3, so that the contact pressure between the friction roller 4 and the fabric body 11 reaches the set contact pressure value, which is convenient for adjusting the contact pressure; by the reciprocating rotation of the first winding component 2 and the second winding component 3 in the same direction, the unwound fabric maintains a stable linear speed and contacts and rubs with the friction roller 4 at a constant speed, which is convenient for adjusting the friction speed between the fabric body 11 and the friction roller 4; by controlling the winding speed of the first winding component 2 or the second winding component 3, when the contact pressure changes, the length of the unwound fabric is dynamically controlled, and then the contact pressure is controlled to maintain the set contact pressure value, thereby realizing automatic adjustment and maintenance of the contact pressure.

[0057] Specifically, the friction roller 4 moves vertically upward when being squeezed by the fabric body 11, so that the friction roller 4 maintains a longitudinal setting posture without rotating, thereby ensuring the accuracy of contact pressure value monitoring.

[0061] Specifically, it is convenient for a person to insert his fingers into the pressing groove 2011 through the opening to pull out the pressure strip 204, and then insert the end of the fabric body 11 under the pressure strip 204, and then release the pressure strip 204, so as to quickly fix the end of the fabric body 11.

[0062] See also Figure 3 and Figure 6 A U-shaped cavity is formed between the pressure strip 204 and the pressing groove 2011. An elastic pin 207 penetrates the pressure strip 204 at the open position of the pressing groove 2011.

[0063] Specifically, by providing an elastic pin 207 and a locking bolt 209 for locking it, the fabric body 11 is passed through the bottom of the pressure strip 204 and then stretched upward, so that the elastic pin 207 is squeezed on the end of the fabric body 11 and locked with the locking bolt 209, thereby improving the stability of the clamping of the end of the fabric body 11 and preventing the fabric body 11 from falling out during reciprocating winding.
