ISO4920 Textile Negative Ion Tester Textile Testing Instruments
Application
It is used to test the amount of negative ions excited by textiles under friction.
Features
In a certain volume of test chamber, install the sample on the upper and lower friction plates and rub it under the specified conditions. Measure the number of negative ions excited in the unit volume space when the sample and the sample rub each other with an air ion measuring instrument, and record the curve of the amount of negative ions with time.
