Classification of fabric antistatic test experiments
Fabric antistatic test is a technical indicator that needs to be tested in the textile industry, especially for specific industries, static electricity must be controlled.
For example, antistatic clothing and other fabric types have clear standard requirements. Of course, antistatic test experiments for fabrics There are many types, including: frictional electrification, ash absorption, static decay, etc. The engineer of this article (Hong Kong) Co., Ltd. will give you a brief introduction:
1. Triboelectric charge measurement method makes the sample triboelectrically charged, and then put it into a Faraday cylinder , the sum of the charges carried by the test.
2. The impedance measurement method selects two points at a certain distance on the surface of the sample, touches them with electrodes, and tests the resistance between the electrodes. It is often used in the evaluation of the antistatic properties of clean clothes, computer room antistatic clothing and carpets.
3. Ash Test (Ash Test) The friction-charged sample is placed close to the dust to determine the degree of dust absorption.
4. The human body voltage measurement method is used to test the antistatic properties of decorative fabrics such as carpets and automobile fabrics.
5. The frictional voltage measurement (Rotary Statics) method makes the sample rubbed with a friction cloth on the rotary disk to test the voltage value due to friction.
6. Electrostatic decay time (Charge Decay) measurement method: Add a certain voltage (usually 5000V) to the sample, test the voltage induced by the sample, and test the time it takes for the charge to decay by half.
7. The walking (simulated walking) test method simulates the way a person walks on the sample to be tested, the shoes and the sample are frictionally charged, and the voltage on the human body is tested. Usually used for carpet antistatic performance test.
8. Friction charged decay method Japanese antistatic fabric test method standard, add a certain voltage (usually 5000V), use cotton and wool friction cloth to automatically rub with the sample, and output voltage and curve at the same time to obtain half-life and static voltage. Fabrics containing conductive fibers can be scientifically tested.
9. The electrostatic adsorption test (Cling) method makes the fabric triboelectrically charged, and tests the time that the electrostatic force of the fabric resists the gravity to adhere to the metal plate.
10. The half-life measurement method makes the sample charged under a certain applied voltage, and tests the time for the voltage on the sample to decay to half of the initial voltage.
More about Fabric Static Tester:
This Fabric Induction Electrostatic Tester is suitable for the determination of the electrostatic properties of fibers, yarns, fabrics, carpets, upholstery fabrics and other fabrics or various plate-shaped finished product under laboratory conditions.
The Fabrics Induction Type Electrostatic Tester host consists of a corona discharge device and a probe detector.Using a given high-voltage electric field, the fabric is discharged for a certain time, causing the fabric to induce static electricity, thereby performing electrostatic energy measurement, half-life of static voltage decay, and electrostatic residual amount to detect the electrostatic charging property of the fabric to be tested.
The seriousness of the charging of the fabric depends on the level of the static voltage after high-voltage discharge and on the other hand. The rate of static escaping on the fabric is expressed by the electrostatic half-life, which is an important indicator for testing the electrostatic properties of the fabric.
