What's so great about wool dryer balls? They are a natural, antimicrobial fiber and help reduce drying time at the same time reducing static. It is recommended that you use 3-5 dryer balls per average load of laundry; the more wool dryer balls you have in the dyer, the faster your drying time. By investing in this set of dryer balls, they will save you money over time.
When you rub two materials together, some combinations can cause or create more static electricity than others. Since static electricity is the collection of electrically charged particles on the surface of a material, various materials have a tendency of either giving up electrons and becoming positive (+) in charge or attracting electrons and becoming negative (−) in charge.
Skin and polyester clothes
A common complaint people have in the winter is that they shoot sparks when touching objects. This is typically caused because they have dry skin, which can become highly positive (+) in charge, especially when the clothes they wear are made of polyester material, which can become negative (−) in charge.
People that build up static charges due to dry skin are advised to wear all-cotton clothes, which is neutral. Also, moist skin reduces the collection of charges.
