Brief introduction of JIS rubbing color fastness tester
Native Japanese industrial standard JIS friction fastness tester based on textile color fastness to rubbing fastness test method of the test method of (JIS L 0849) specified in the friction tester Ⅱ form (learn vibration shape) is a standard machine.
It is mainly used to evaluate and judge the color fastness to friction of dyed fiber products.
The instrument is also suitable for flocking strength test of flocking processing cloth, friction and decolorization test of artificial leather, friction and wear test of paperboard, printing ink, coating, etc.
It is a friction testing machine suitable for a variety of materials.
The test principle of
In friction fastness tests: about 220 * 30 mm sample installed in the sample stage, about 50 * 50 mm friction with white cotton cloth (dry or wet state) installed in the front of the various friction head, under the weight of 2 n, at a speed of 30 per minute reciprocating do on 120 mm distance between 100 reciprocating motion, then white cotton cloth to remove, and assess the generalization of the grey CARDS are compared.
In the organic solvent rubbing fastness test: simulates the colour fastness of the fabric when cleaned with organic solvent.
During the test, the sample and the undyed cotton cloth stained with organic solvent were rubbed together in a certain way using the friction tester, and then the discoloration and seqing condition of the undyed cotton cloth were evaluated with the discoloration grey card and the stained grey card respectively.
In the test of the wear resistance of cardboard surface: under the pressure of 500g, the friction head and the width of 20mm cardboard friction to each other
Test standard
This friction color fastness tester meets the following standards:
JIS L0849 (Ⅱ) rubbing fastness test method (Ⅱ type)
JIS L0862 (Ⅱ) organic solvent friction fastness test method (Ⅰ type)
JIS L1084 Flocking Fabric Test (Colour fastness and flocking strength)
Test Method for wear resistance of JIS P8136 paperboard

Test method for
In a standard JIS L0849 (Ⅱ) as an example, introduces the use of the instrument.
Sample preparation
The size of the sample is about 220*30mm and it is cut parallel to the meridional and zonal directions.
The size of friction white cotton cloth is about 50*50mm.
When the sample is silk, approximately 220*30mm rectangular plate should be used, tightly wound in the direction of its long side to form a thin layer, or properly woven and used as a sample.
During the drying test, the sample and friction white cotton cloth should be prepared in the standard state for more than 4 hours in advance.
During the wetting test, the friction white cotton cloth is wetted with water to make it reach 100% wetting state. The sample is placed in the standard state for preparation.
Note:
Standard state of the sample: prepare and dry the sample (40±5℃ desiccant), make the moisture content below the common moisture content, then put it into the laboratory or device in the standard state (temperature 20±2℃, humidity 65±2%), make it reach the constant weight state.
The standard of the constant weight of the sample: the sample is placed in the laboratory and device in the standard state. When continuously reading and weighing, the quality of the sample is weighed at intervals of more than one hour. When the difference of the quality of the sample before and after weighing is within 0.1% of the next weighing, the state of the sample is.
test
Sample installation: first fix one end of the sample with the test fixture on the inside, then fix the other end with the test fixture on the front.
In order to make the sample not slack, the sample is fixed by slightly straining it.
When the specimen is a stretchable specimen, double-sided tape can be used to fix it on the test bench.
In addition, it will be difficult to install the sample when the sample table stops at the inside position, so you can press the inching button and then move it to the front position of the hand.
White cotton cloth for mounting friction: lift the friction head bracket and lean against the rear pole.
Lay white cotton cloth on the friction surface (surface) and secure it with square spring clamps.
Please note that no wrinkles should appear on the white cotton cloth at this time.
Place the friction head bracket on the sample table. Please confirm the position of the sample table in front of your hand before lowering the friction head bracket. If it is not in front of your hand, inching button will move it to the front of your hand before lowering the friction head bracket.
Turn on the power switch and set the counter number.
Inching the start button, the machine starts reciprocating motion, and automatically stops when it reaches the set number.
If you want to stop the test, please press the stop button.
Judge test results: After the test, judge the friction white cotton cloth according to JIS 0801's 9(determination of dyeing fastness).
(Compare with the grey sample card used to evaluate coloration)
Matters needing attention
During the learning and use of the instrument, please pay attention to the following points:
When the machine is running, please pay full attention, do not touch the sample, test bench and other moving parts, so as to avoid finger injury.
When placing the friction head bracket on the test bench, be careful to place it gently.
When put down forcefully, it will cause the surface of sample table concave or appear scar.
The stop button is not normally used, please use it when you need to stop the run during the test.
Please refer to relevant standards for detailed test methods and test conditions corresponding to test samples.
