Textile antistatic test methods - Antistatic tips

What are the methods for testing the antistatic properties of textiles?

1. Rotary Statics method

Principle: Under a certain tension condition, the sample and the standard cloth are rubbed against each other, and the highest voltage and the average voltage generated at this time are evaluated. Note: When the electrostatic properties of the front and back sides of the sample are quite different, both sides should be measured.

2. Triboelectric charge measurement method

After the sample is frictionally charged with static electricity, it is placed in a Faraday cell to test the sum of the charges.

3. Impedance Assay

Select two points at a certain distance on the surface of the sample, contact them with electrodes, and measure the inter-electrode resistance.

It is often used to evaluate the antistatic performance of dust-free clothing, computer room antistatic clothing and carpets.

4. Human body voltage measurement method

It is used to test the antistatic performance of decorative fabrics such as carpets and automotive fabrics.

5. Electrostatic adsorption test (Cling) method

Triboelectrically electrify the fabric and test the time it takes for the fabric to adhere to the metal plate against the force of gravity by electrostatic force.

6. Electrostatic decay time (Charge Decay) measurement method

Apply a certain voltage (usually 5000V) to the sample, test the induced voltage of the sample, and test the time it takes for the charge to decay by half.

7. Walking (simulated walking) test method

Walk on the tested sample in the way of simulating human walking, the shoes and the sample are frictionally electrified, and the voltage carried by the human body is tested. It is usually used to test the antistatic performance of carpets.

8. Half-life Assay

The principle is to make the sample charged to a stable high-voltage electrostatic field, disconnect the high-voltage power supply, and make its voltage decay naturally through the grounded metal platform. Measure the time required for its voltage to decay to half of its initial value. Half-life performance technical grade requirements: Grade A≤1.0S, Grade B≤5.0S, Grade C≤15.0S. Anti-static work clothes should reach A-level indicators, and daily-use clothing (functional) should reach B and C-level indicators.

9. Ash Test

The triboelectrically charged sample is brought close to the dust, and the degree of dust adsorption is judged.

10. Frictional electrification decay method

The Japanese antistatic fabric test method standard, apply a certain voltage (usually 5000V), use cotton and wool friction cloth to automatically rub the sample, and output the voltage and curve at the same time to obtain the half-life and static voltage. Fabrics containing conductive fibers can be scientifically tested.
