Applicable scope:

Lay the sample flat and fix it on the clamp, so that the wet abrasive fixed on the friction head can perform reciprocating friction motion on the sample at a certain range of motion under the specified load until the specified number of times. Then, compared with the sample, visually evaluate the degree of fiber adhesion on the abrasive to characterize the degree of sample shedding. For various factories, research institutes, colleges and universities, import and export inspection, and textile testing instruments in various provinces and cities.
