You can choose anti-static clothing that meets the company's use requirements according to the following principles
1. Choose from ESD performance. Under the premise of cost control, the better the ESD performance, the more you can meet the company's requirements;
2. Choose from the cleanliness. Anti-static clothing not only has ESD functions, but also has an important function, that is, the cleanliness index. On the premise that the static electricity index meets the requirements, choose a clothing system with good cleanliness;
3. Choose from clothing styles, the anti-static index of one-piece clothing is better than that of split clothing;
4. Choose from the characteristics of the fabric. The surface-coated fabric has the worst ESD performance. Choose the fabric blended with composite filament and conductive yarn as much as possible.
5. Choose from the size of the anti-static grid. In theory, the larger the grid, the worse the anti-static effect, such as 5mm striped fabric, ESD performance is worse than 5mm grid fabric, the best ESD performance is 2.5mm fabric;
6. From the choice of service life, you need to choose wear-resistant and wash-resistant clothing. Generally, the good domestic anti-static clothing has a service life of 2 years or more (according to the weekly replacement and cleaning, the life is about 100 times) ), the difference is only about 50 times and it has not met the requirements.
7. Choose from the level of comfort. If the ESD performance meets the standard, but the staff is very uncomfortable after wearing, it will not meet the requirements, so if only ESD requirements and no cleanliness requirements, choose a fabric with good air permeability, but if there is cleanliness Requirements, you must choose a balance between comfort and product requirements;
8. In addition, it is necessary to select the appropriate size from the height and body shape of the employees. Anti-static clothing that does not meet the height and body shape will affect the production operation on the one hand and will accelerate the elimination of dust-free clothing on the other hand.
9. In terms of frequency of use, frequent wear and tear in the process, such as cuffs, elbows, etc.; the replacement interval is too long or the cleaning frequency is low, which makes the cleaning of the fabric more difficult, thereby speeding up the conductive wire in the fabric Ageing.
