What is the common name for fiber-resistant clothing made by Dupont?

The common name for fiber-resistant clothing made by DuPont is Tyvek. Tyvek is a brand of synthetic material made from high-density polyethylene fibers, which is known for its durability, resistance to water, and ability to protect against particulates and chemicals.

Tyvek is widely used in personal protective equipment (PPE), including coveralls and suits, commonly utilized in the construction, hazardous waste handling, and chemical manufacturing industries, due to its breathable yet protective qualities. This makes it an ideal fabric for situations where contamination by fibers or hazardous materials is a concern.

The other options mentioned, such as polyester suits, burlap coveralls, and nylon suits, do not provide the same level of specialized fiber resistance and protection that Tyvek offers, thereby making them less suitable for occupational hygiene monitoring where protection against hazardous exposures is necessary.
