Overview
The AISRY friction colour fastness tester is used to rub colored test pieces with a specific load and number of times by drying or wetting white cotton cloth, and then to evaluate the dyeing friction fastness grade against the grey standard. The device can also be used for friction testing of organic solvents.
Features
1. Adopt an electronic 6-digit counter for accurate counting.
2. Friction hammer load and auxiliary load can be adjusted to meet different testing requirements.
3. Compact design, machine size is approximately 50x55x35 centimeters.
4. Multiple sets of friction tests can be performed simultaneously, and the number of friction groups is 6.
Principle
The device drives the friction hammer to reciprocate through the motor. The white cotton cloth is fixed on the surface of the friction hammer, and the specified load is applied to the colored test piece placed below to rub. After the set number of friction times, the dyeing friction fastness grade of the test piece is evaluated by observing the color change of the test piece and comparing it with the gray standard.
Applications
Spinning & weaving, leather
Standards
JIS-L0801、0823、0849、1006、1084、K6328、P8236
Steps
1. Prepare the sample, measuring 22x3 centimeters.
2. Tie the drying or wet white cotton cloth (the friction area is about 5 * 5 cm) on the surface of the friction hammer.
3. Fix the specimen on the test bench.
4. Set parameters such as the number of frictions.
5. Start the machine, and the friction hammer is rubbed at a speed of 30 times per minute under a load of 200g and an auxiliary load of 300g.
6. After the friction is completed, remove the sample and grade it against the gray standard.
Notice
• Please confirm that the power supply is AC 220V 50Hz before use.
• Make sure that the white cotton cloth is tied evenly on the surface of the friction hammer to ensure the accurate friction area.
• According to the requirements of the test standard, choose the correct drying or wet friction cloth.
• Regularly check whether the load and movement of the friction hammer are normal.
The weight of the machine is about 60kg, and attention should be paid to safety when moving and placing.
