According to the different use occasions of antistatic textiles, various industries also have different technical requirements. Therefore, product standards and corresponding technical requirements for different industries are divided, mainly including: military industry, special industries, civilian use, etc. Our country has formulated GB 12014-2009 “Anti-static Clothing”, GB/T 24249-2009 “Anti-static Clean Fabric”, GBT 22845-2009 “Anti-static Gloves” and other standards to serve special industries as needed, as well as supporting labor protection The product’s GB/T 23464-2009 “Standard for Anti-static Wool Knitted Clothing” and other related product standards. The test methods and technical requirements of the above standards are introduced below.
As can be seen from the table above, textile antistatic testing has relatively strict environmental requirements. This is because temperature and humidity have a greater impact on antistatic indicators and directly affect the accuracy and repeatability of test results. Therefore, it is usually necessary to conduct testing in a constant temperature and humidity laboratory that meets the test conditions.
In the anti-static test in the currently more commonly used product standard GB 12014-2009 “Anti-static Work Clothing”, the possible factors that cause large deviations in the test results include the following aspects: whether the specific operation of the washing procedure complies with the standard; humidity control after washing process (according to the requirements of Appendix A5 of the standard, the humidity should be adjusted and tested after 24 hours); washing machine and friction machine, whether these two key equipments meet the standard requirements; whether the friction machine has a timing function, and whether it has a discharge or static electricity removal function; test When the sample is taken out of the friction machine after rubbing, whether it should be entered directly according to the standard requirements or operated with insulating gloves.
