Anti-static textile evaluation criteria
The anti-static function of textiles is usually obtained by means of special finishing (coating, surface metallization, etc.) and using conductive fiber materials (metal fibers, metal coating fibers, conductive composite fibers, etc.) According to the fabric selection test method
The evaluation of antistatic properties of textiles should be based on the different properties of the fabric using different methods, test items vary from one method to another. Static tests include static parameters of the static test, static testing of materials and products, electrostatic susceptibility testing of flammable and explosive materials. The main parameters that characterize the electrostatic properties of materials or products are resistivity, leakage resistance, charge density and half-life, triboelectric charging voltage and half-life. The evaluation of electrostatic properties of textile materials are mainly indicators of resistance type, electrostatic voltage and half-life, charge density and other indicators, as well as simple low-precision test indicators such as ash absorption test, Zhang Fan test, adsorption metal sheet test. Test method type
China currently used in textiles, apparel anti-static performance testing of the national and industry standards are: GB / T12014-1989 "anti-static overalls", GB / T12703-1991 "static test methods for textiles", FZ / T01042-1996 "textile materials FZ / T01044-1996 Determination of Electrostatic Property Fiber Leakage Resistance of Textile Materials FZ / T01059-1 999 Method of Measurement of Frictional Electrostatic Adsorption FZ / T01060-1999 Fabric Friction Determination of charged charge density ", FZZY0 1061-1999" Determination of triboelectric triboelectric voltage. " The company is located in:
It must be noted that the applicability of different test method standards is different. Take GB / T12703-1991 Textile Electrostatic Testing Method as an example, this method provides several different testing methods. Not only the testing items are different, the technical conditions are different, but also the applicable products are different, and the meanings of the tests are also different. Such as:
A method (half-life method, the same as FZ / T01042-1996): With +10 kV high voltage on the optional metal platform on the sample discharge 30s, measuring the half-life of the induced voltage (s). This method can be used to evaluate the electrostatic decay characteristics of fabrics, but the contact state of the conductive fiber-containing samples on the grounded metal platform can not be controlled. When the conductive fibers contact well with the platform, the charge rapidly leaks. When the contact is poor, Similarly, the test results obtained by the same sample under different conditions are very different, so it is not suitable for evaluating the antistatic performance of the fabric containing conductive fibers. The company is located in:
B method (triboelectric charging voltage method, basically the same as FZ / T01061-1999): 4 samples (2 by 2 latitudes and 4 cm × 8 cm) were placed on the drum, the drum at a speed of 400r / min and Standard cloth (nylon or polypropylene) friction, test within 1min maximum charged voltage of the sample (V). This method because the sample size is too small, woven fabric woven conductive fibers, the distribution of conductive fibers with the sampling location will have a great difference, it is not suitable for evaluation of antistatic properties with conductive fiber textiles . The company is located in:

C method (charge density method, basically the same with the FZ / T01060-1999): Specimen in the specified conditions and nylon standard cloth friction Faraday cup after the charge measured by the sample size to obtain the charge density (μC / m2). The charge density method is suitable for evaluating the ease of electrostatic accumulation of various fabrics, including the conductive fiber-containing fabrics by friction. The measured results are closely related to the gray level of the sample. Due to friction triboelectricity between the sample and the standard cloth is achieved by manual operation, the consistency of the test conditions, the accuracy and reproducibility of the test results are susceptible to manipulation. The company is located in:
D method (clothing strip method): according to a specific way to rub the overalls and chemical fiber underwear after taking off uniforms, into the Faraday cup, get the charge (μC / piece). The test object of this method is limited to clothing, but because of the material underwear is not provided, friction is difficult to unanimous, lack of comparability. The company is located in:
Looking at the existing national and international standards for testing the electrostatic properties of textiles, the actual testing method for the electrostatic properties of fabrics containing conductive fibers is only the surface charge density method of GB / T12703-1991 or FZ / T01060-1999. Therefore, the evaluation of the antistatic properties of textiles does not require the determination of a certain correlation between different indicators, but should establish a complete and multi-lateral evaluation system to reflect the textile under different test conditions and conditions Antistatic properties and the actual use of results. Some experts suggest that the existing charge density method should further study and improve the relevant test conditions, the manual friction to automation, in order to further improve the accuracy and reproducibility of the test
