Scott Type Crease-Flex Abrasion Tester TF119
Scott Type Crease-Flex Abrasion Tester, to determine the crease-flex abrasion resistance of leather, rubber cloth etc. Scott Type Crease-Flex Abrasion Tester complies with GMW 3217, etc.
Scott Type Crease-Flex Abrasion Tester, to determine the crease-flex abrasion resistance of leather, rubber cloth, etc. This test method is used to determine an automotive seat fabric’s resisitance to ravelling during seat cover manufacture and during normal vehicle life. This test is recommended for woven fabrics without lamination or with laminates up to 5 mm thick.
Clamp the two specimens in cross shape. Based on the various materials of the specimen, apply the appropriate load. The force loaded on specimen, distance between grips and the two-way distance can be adjustable. And the force loaded on specimen is of spring type. During the test, two specimens undergo crease abrasion and reciprocal movement. After reaching the specified number of abrasions, remove the test specimens and inspect them for cracks, wrinkles, or discolouration.
Holders: 0~50mm(standard: 30mm)
Pressure load: 9.8N (adjustable)
Friction distance: 0~60mm(standard: 50mm)
Friction speed: 120+/-2cpm
|220 V||50/60 Hz|
|Length: 500 mm||Width: 580 mm||Height: 350 mm|
1 Prepare specimens of suitable size and condition them according to standard GMW 3221 code A.
2 Separate the jigs by (30 ± 3) mm and secure the specimen in the jigs.
3 Place the two sets of jigs together, ensuring that the loose fabric is only allowed to fold once on each side of the jig.
4 Perform 1000 tests at a speed of 120 cpm and a stroke length of 50 mm.
5 Test the other specimens in the same way.
After the test, assess the specimen rating according to the table below.
|Rating||After 1000 cycles|
|10||No apparent ravelling or yarn slippage in the fabric structure.|
|8||Slight, non-objectionable ravelling and/or minimal yarn slippage in the fabric structure. No ravelled threads span the tested length.|
|6||Moderate ravelling or yarn slippage with a maximum of one ravelled thread spanning the tested length.|
|4||Significant ravelling or yarn slippage with a maximum of three ravelled threads spanning the tested length.|
|2||Excessive ravelling or yarn slippage with a maximum of five ravelled threads spanning the tested length.|

The Scott Type Crease-Flex Abrasion test determines the durability of the product by rubbing back and forth on the sample and then observing the degree of crack, wrinkles, or discoloration of the sample. Scott crease-flex test and Martindale abrasion test are used to testing the durability of textiles from different angles, so the combination of them can improve the stability of the test results.
Differences between Martindale abrasion test and Scott Type abrasion test
1. Different testing methods: the Martindale abrasion test mainly implement friction between the tested sample and the specified substance, while the Scott Type crease-flex abrasion test is rubbed back and forth with the sample itself.
2. The testing range is different: the Martindale abrasion tester is mainly used to test the pilling ability of textiles to judge the durability of fabrics, while Scott Type crease-flex abrasion tester not only can test the durability of textiles but also can test the rubbed strength of the plastic film, artificial leather, rubber cloth and leather.
3. Different test standards: the Martindale abrasion test mainly meets international standards, while the Scott crease-flex abrasion test is mainly aimed at some of the standards in Japan. For example, JIS L1096 accord with the Japanese industrial standard, JASO conforming to Japanese Automobile Standards, JIS-K6404-6 conforming to Japanese Rubber Industry Standard, is a more professional test.
Scott Type crease-flex abrasion tester is easy to operate and practical. Please contact us if you want to buy it.
