In order to reduce the static electricity of sweaters, some measures can be taken. For example, wiping the sweater with a wet towel before wearing it, or adding a softener to the water, and wiping the sweater after the towel touches it, can increase the wetness of the sweater and reduce the occurrence of static electricity. In addition, you can also rub the battery on the surface of the sweater once to eliminate static electricity. In the dry winter, reducing the number of wearing sweaters or choosing to wear pure cotton clothes as much as possible can also effectively reduce the generation of static electricity.
