In the process of processing and wearing, medical non-woven fabrics will rub against the human body and various objects to generate static electricity. If the conductivity of the fiber or the object is not good, the charge is not easy to escape, which will often affect the production and processing and reduce the quality of the fabric. Clothing is easily stained when static electricity is generated, and the phenomenon of entanglement occurs, which makes the human body inconvenient, uncomfortable and unsightly to wear, and even causes a fire.
The strength of the static electricity charged by the material can be expressed by the charge half-life, that is, the time required for the electrostatic voltage or charge on the fiber material to decay to half of the original value; it can also be expressed indirectly by the specific resistance of the fiber. The maximum charge amount of various fibers is roughly the same, but the static attenuation speed is very different. The surface specific resistance of the material is reduced to a certain level. One-time, medical disposable surgical gowns consider static electricity issues to prevent static electricity from occurring.
