JIS Gakushin type friction color fastness tester experimental steps
JIS Gakushin type friction color fastness tester is mainly used for the evaluation and determination of the friction color fastness of dyed fiber textile products, which conforms to the Japanese JIS series standards.
Shanghai Qianshi Precision Electromechanical Technology Co., Ltd. was established in 2012. It focuses on the research and development, design, and production of textile testing instruments, and provides textile testing instruments and services for academic research units and testing institutions. Shanghai Qianshi is one of the most competitive R&D textile testing instrument manufacturers in China. The R&D team is composed of a group of experienced engineers. We are committed to serving customers wholeheartedly and striving to promote the technological innovation of textile testing instruments.
Test principle:
Use dry or wet white cotton cloth to tie the surface of the friction head of the machine. According to the prescribed method, rub the sample and the friction white cotton cloth against each other. Compare the staining degree of the friction white cotton cloth with the staining rating gray sample card against the gray standard to evaluate the dyeing friction fastness grade.
Experimental steps:
1. Install the sample: First, fix one end of the sample with the inner sample clamp, and then fix the other end with the front sample clamp. To prevent the sample from loosening, tighten the sample slightly to fix it. When the sample is tensile, it can be fixed on the test bench with double-sided tape. In addition, because it will be difficult to install the sample when the sample table stops at the inner position, you can press the inching button at this time and then move it to the front side of the hand.
2. Install the white cotton cloth for friction: lift the friction head bracket and lean it on the rear leaning rod. Spread the white cotton cloth on the friction surface (curved surface), and then fix it on it with a square spring clamp. Please note that there should be no wrinkles on the white cotton cloth at this time.
3. Put the friction head bracket down on the sample table. Please confirm that the sample table is on the front side of the hand before putting down the friction head bracket. If it is not on the front side of the hand, press the inching button to move it to the front side of the hand and then put down the friction head bracket.
4. Turn on the power switch and set the counter times.
5. Press the start button, the machine starts to reciprocate and stops automatically when the set number of times is reached. If you need to stop the test midway, please press the stop button.
6. Determine the test results: After the test, judge the friction of white cotton cloth according to 9 (dye fastness determination) of JIS 0801. (Compare with the gray sample card for staining)
