Test principle and operation steps of Japanese standard rubbing color fastness t
The Japanese standard rubbing color fastness tester complies with the Japanese JIS series standards and is used to evaluate and determine the color fastness of rubbing dyed fiber textile products. The equipment is independently produced by our company Shanghai Qianshi Precision Electromechanical Technology Co., Ltd. It has high-cost performance and fast and complete after-sales service. Customers with needs are welcome to call for inquiries.
Applicable standards:
JIS L0801-2004 General rules for color fastness test methods;
JIS L0823, JIS L1006;
JIS L1084-2009 Test method for flocked fabrics;
JIS K6328-1999 Test method for rubber-coated fabrics;
JIS P8136 Determination method for abrasion resistance of cardboard;
JIS L0849-2004 Type II (Xuezhen type) test method for color fastness to rubbing.
Test principle:
Friction color fastness test: Install a sample of about 220*30mm on the sample table, and install a friction white cotton cloth of about 50*50mm (dry or wet) at the front end of each friction head. Under a load of 2N, make 100 reciprocating movements at a speed of 30 times per minute at a distance of 120mm, then remove the white cotton cloth and compare it with the gray sample card for staining assessment for evaluation.
Organic solvent friction color fastness test: simulate the color fastness of fabrics when washed with organic solvents. During the test, the sample and the undyed cotton cloth stained with organic solvent are rubbed against each other in a certain way using a friction tester, and then the discoloration of the sample and the staining of the undyed cotton cloth are evaluated using the discoloration gray card and the staining gray card respectively.
Operation steps:
Install the sample: First, fix one end of the sample with the inner sample fixture, and then fix the other end with the front sample fixture. 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, since it is difficult to install the sample when the sample table stops at the inner position, you can press the inching button at this time and move it to the front of the hand.
Install the white cotton cloth for friction: lift the friction head bracket and lean it on the rear support rod. Spread the white cotton cloth on the friction surface (curved surface) and 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.
Put the friction head bracket down on the sample table. Please confirm that the sample table is in the front of the hand before lowering the friction head bracket. If it is not in the front of the hand, press the inching button to move it to the front of the hand and then lower the friction head bracket.
Turn on the power switch and set the counter number.
Press the start button, and the machine starts reciprocating and stops automatically when the set number of times is reached. If you need to stop the test midway, press the stop button.
Judge the test results: After the test, judge the 9 pairs of white cotton cloth for friction according to JIS 0801 and compare them with the gray sample card for evaluating staining.
