Dying Rubbing Fastness Tester（Model: G238BBC）
The Dying Rubbing Fastness Tester is a laboratory instrument used to determine the resistance of dyed textiles to dry and wet rubbing. The test is performed by a standard-weight rubbing head executing reciprocating linear motion at a specified speed and stroke length. After completion of the preset number of cycles, the motor automatically stops, ensuring consistent and repeatable test results.
Application
The Dying Rubbing Fastness Tester is suitable for evaluating dry and wet rubbing fastness of various textile materials, including:
Cotton, wool, linen, and silk fabrics
Knitted fabrics
Printed and dyed textiles
The instrument is used in textile manufacturing, printing and dyeing industries, quality inspection laboratories, and research institutions.

Test Procedures
Fix the textile specimen securely on the test table.
Select dry or wet rubbing mode according to the test standard.
Set the required number of rubbing cycles on the control interface.
Start the test; the rubbing head performs reciprocating motion under standard load.
After completion, remove the specimen and evaluate rubbing fastness using the appropriate gray scale.
Maintenance Information
Keep the rubbing head and test table clean and free of fiber residue.
Periodically inspect the rubbing head load and stroke accuracy.
Replace worn sandpaper cushions as required by the test standard.
Disconnect power when the instrument is not in use for extended periods.
