Very comprehensive leather rubbing color fastness tester scientific guide
The leather rubbing color fastness tester is an instrument for testing the rubbing resistance of leather materials. It evaluates its color fastness performance by simulating the friction force of leather during use and measuring the degree of color change. During the test, the leather sample is fixed on the test bench, and then rubbed against its surface with a certain force and speed, and then the degree of color change is measured with a colorimeter or spectrometer, and finally its color fastness grade is obtained. This tester is widely used in the fields of production and quality inspection of leather products.
The leather rubbing color fastness tester continuously rubs the friction head on the leather surface to simulate the wear of the leather during use, and then uses a color difference meter or a colorimeter to measure the degree of change in the color of the leather to evaluate the color fastness of the leather. This test method can help manufacturers determine whether the color fastness of leather products meets the standards, and improve product design and production processes to improve product quality and competitiveness.
The following is the process of using the leather rubbing color fastness tester:
1. Preparation: Place the tester on a stable workbench, plug in the power and turn on the power switch, and wait for the tester to enter the standby state.
2. Prepare test samples: Cut the leather samples to be tested into the specified size and shape according to the requirements, and record the number and related information of each sample.
3. Debugging before testing: According to the instruction manual of the tester, adjust the friction head, load, speed and other parameters of the tester to ensure that the test conditions meet the standard requirements.
4. Test operation: Fix the test sample on the tester, place the friction head on the surface of the sample, and start the tester to start the test. During the test, pay attention to observe the display screen of the tester and the changes on the surface of the sample, and record the test data and results.
5. Treatment after the test: After the test is over, remove the test sample and perform necessary treatment, such as cleaning, drying, drying, etc. At the same time, organize and record the test data.
6. Analysis and judgment of test results: Analyze and judge according to test results and standard requirements, and draw test conclusions. If necessary, repeated tests or other related tests can be carried out to further verify the accuracy and reliability of the test results.
7. Maintenance and maintenance of test equipment: After the test, the test equipment should be cleaned and maintained to keep the equipment in good condition for the next test use. At the same time, regular equipment maintenance and repairs are required to ensure the performance and accuracy of the tester.
It should be noted that when using the leather rubbing color fastness tester, the operation must be strictly followed to ensure the accuracy and reliability of the test results. At the same time, regular inspection and maintenance are required to ensure the normal operation and long-term stability of the tester.
