In addition to the sensitivity requirements of the product itself to static electricity, most clean rooms require the environment to be in constant temperature and humidity conditions for a long time. The static electricity generated in the clean room is more difficult to eliminate. The electrostatic control performance of the clean clothes is especially important.
Therefore, it is certain that the clean clothes of biopharmaceutical companies also need antistatic properties.
Here we talk about how to ensure the anti-static performance of clean clothes, the anti-static effect of a piece of clothing is good, and has a fundamental correlation with the selected fabrics and the craftsmanship.
There are two main ways to ensure the electrostatic performance of clean clothes. One is to choose a fabric with good antistatic performance, and the other is to ensure the electrical connectivity of the garment as a whole.
Good grounding when wearing.
The anti-static fiber resistance, the amount of addition and the way of adding determine the anti-static properties of the fabric.
In the case where the area is constant, the greater the amount of antistatic fiber added, the better the antistatic property of the fabric. Different amounts of fabric can be selected according to the electrostatic sensitivity level of the clean room. Antistatic fibers are generally black or gray, so the appearance of the embedded antistatic fibers is generally black stripes or lattices.
To ensure the electrical continuity of the whole clean clothes, conductive sewing threads must be used; for some clean clothes with extremely high static electricity requirements, conductive tape must be used in the splicing part of the fabric, and conductive ribs should be used at the cuffs and feet; if necessary, clean Add a grounding point to the appropriate position of the suit. The use of these excipients is an intuitive basis for judging the electrostatic performance of clean clothes.
