In the textile industry, antistatic properties are an important indicator that is commonly used to assess whether textiles can generate problems caused by static electricity during use and wear.
Below are a few common test methods for textile antistatic properties:
1. Surface Resistance Test: This test method is used to measure the resistance of the textile surface to determine its conductive or insulating properties. The test is usually performed with a surface resistivity meter or test apparatus according to the standard ASTM D257. The test sample should be prepared in the specified size. Please make sure that the surface of the sample is clean and free from any contaminants that may affect the test.
2. Electrostatic Charge Test: This test method is used to measure the amount of electrostatic charge generated by textiles under friction or other stimuli. Commonly used test equipment are electrostatic charge meters or electrostatic charge balance methods. These devices can be used to quantitatively measure the electrostatic charge of textiles and provide relevant charge property data.
3. Electrostatic Dissipation Time Test: This test method is used to evaluate the time it takes for a textile to go from a charged state to a fully dissipated charge. A common test method is the use of an electrostatic dissipation meter. During the test, the sample is charged and the dissipation time is recorded, with a shorter time indicating a better dissipation of static electricity in the textile.
4. Electrostatic field test: This test method is used to measure the strength of the electrostatic field generated by the textile. An electrostatic field meter or other appropriate equipment is used and placed around the textile to measure the strength of the electrostatic field. This helps to assess the antistatic properties of the textile and to prevent static build-up.
5. Human Simulation Test: This test method is used to assess the effect of textiles on human electrostatic discharge. Commonly used test equipment includes human body simulators and electrostatic charge meters. During the test, friction or contact is simulated between the textile and the human body, and the associated electrostatic charge and release time are measured.
These textile antistatic test methods can be selected as applicable according to requirements and relevant standards. Specific test procedures and operating steps should follow the recommendations of the respective standards or equipment manufacturers. In order to obtain accurate test results, it is necessary to use appropriate test equipment and to ensure that the test environment meets the requirements in order to exclude the influence of any interfering factors.
