1. Anti-static performance After controlling the cost, you can choose clothes with better anti-static performance to meet the needs of the company.
2. Cleanliness and dust-free clothing It not only has the performance of ESD, but also has a key function, that is, cleanliness index. Under the condition of ensuring that the electrostatic index reaches the standard, you can choose clothes with good cleanliness.
3. Fabric characteristics: try to choose the fabric woven by composite yarn and conductive yarn, and the antistatic performance of the surface coating is weak.
4. Compared with the split dust-free suit, the one-piece dust-free suit has a better antistatic index.
5. Service life At present, domestic dust-free clothing can generally reach more than 2 years (cleaning once a week is about 100 times), and it will not meet the demand if it is 50 times worse.
6. The larger the wire grid, the worse the antistatic effect. 2.5M cloth has good antistatic performance.
7. Suitability If only ESD performance meets the standard, but employees are uncomfortable to wear it, then it does not meet the requirements. If there is no cleanliness requirement, then choose a balance point between product demand and comfort.
8. Size and model Choose the dust-free clothing model suitable for employees' body shape, height and weight, otherwise inappropriate dust-free clothing will affect production.
9. Frequency of use If the cuffs and elbows are often worn during the process, less cleaning frequency or too long replacement time will cause the aging of the conductive wire.
