[Textile Testing] Textile antistatic test methods

01. Friction charged voltage measurement method

 

Principle: Under certain tension conditions, make the sample and standard cloth rub against each other, to the highest voltage generated at this time and the average voltage evaluation. Note: When the sample front and back electrostatic properties are different, both sides should be measured.

 

02. Friction charged charge measurement method

 

After the sample is rubbed with static electricity, it is put into a Faraday cylinder and the total amount of charge is tested.

03.Impedance measurement method

 

Select two points at a certain distance on the surface of the specimen, contact them with electrodes, and test the inter-pole resistance. It is commonly used in the evaluation of antistatic performance of dust-free clothes, computer room antistatic clothes and carpets.
