Which material is considered a good static electricity insulator?

• A. Nylon
• B. 100% cotton
• C. Polyester
• D. Leather

Answer: (B)

100% cotton is regarded as a good static electricity insulator because it is a natural fiber that does not easily accumulate static charges. Unlike synthetic materials, which can generate static electricity through friction, cotton has properties that allow it to dissipate charges rather than hold them. This characteristic makes 100% cotton a preferable choice in environments where preventing static electricity buildup is crucial, such as in the handling of sensitive electronic components. Other materials listed, such as nylon, polyester, and leather, can carry static charges more easily under friction and do not dissipate charges as effectively as cotton. Hence, they are less effective as insulators against static electricity compared to 100% cotton.
