Burning identification method: cut a small cloth strips or pull a few fibers how to clean washing machine lit burning, based on the observed fiber combustion, with or without shrinkage and melting, burning difficulty, flame color, burning rate, flavor, color and character to determine the ashes. Before combustion, can be extracted first twist warp or weft yarn or open to see if they are short fibers. If you are short fibers of varying lengths is cotton, wool and other days of burning fibers; if the fiber length of the same, it is a viscose fibers or synthetic fibers. If the filament, it may be sticky filaments how to clean washing machine or silk. Difference between the two is the sticky filaments brighter than silk. The yarn was then tongue moist places such as wet sticky filaments how to clean washing machine is easy to pull off, if constantly how to clean washing machine wet place, is silk.
