Testing Item： Electric Friction Decolorization Test
Test Principle: Testing Colour Fastness Strength of Fabric By Machine
Attention Point：
A.testing way divide into Dry Friction and Wet Friction
B.Set counter to 10 times
C.Testing panel split into nylon fabric（right picture, CODE: N）
and cotton fabric(left picture，CODE:C),it's necessary to put them into separate box
and write the titles on it.
Power-on state

Attention Point：
- Dry Friction：
- Using ATTC cotton wrap the head of the Friction and chuck the Friction head
- The test board size is150mm*200mm, the distance of Friction keeps105mm, with a strength of 9N, speed 60times per min, testing 10 times
- When 50mm*200mm testing materials are put into the machine board, chucking and laying down the Friction head
2.WetFriction：
- Testing way and testing materials size same as dry friction.
- Using distilled water soak cotton testing fabric 3mins(the water only can use once.)
- Pat dries the testing cotton fabric with a towel before wrapping the friction head
- Open the machine that processes the friction testing
- The machine should be stopped when settled testing times finish.

Proceed Friction Testing
The machine should be stopped when settled testing times finish
Attention Point：If you want to make some marks on the testing fabric, must use a pencil and write smaller
Attention Point：
Put the testing cotton fabric together with the pollution color swatch into a multifunctional light color matching box for judging the pollution level of the testing fabric
A.Dry Friction： if the pollution level is up from LV.4(including LV.4), the result is OK.
B.Wet Friction： if the pollution level is up from LV.3(including LV.3), the result is OK.
