Basic Facts About Tyvek Coveralls

By Essie Osborn


Have you ever seen these distinctive, life-saving garments? If you've seen a one-piece, full-body garment, white, worn by a worker at a construction site, a laboratory, or even by a mechanic in a garage, you've probably seen Tyvek coveralls. They protect the wearer against basic hazards, especially aerosol materials, airborne particulate matter, and even some liquids.

Many protective clothing materials are manufactured by taking a simple fabric, and adding another more complex layer of protective film, separate from the textile itself. Typically, a fabric will be coated or lined with a layer of protective materials. However, with Tyvek the barrier is flashspun right into the threads of the textile itself, so that it can't be scratched or worn away.

Some coveralls have open wrists and ankles, whereas others offer an elastic closure at these extremities. The elastic causes the fabric to hug the wearer's joints. That means additional protection, and less chance there is of a hazardous substance making its way inside the suit, where it can become dangerous.

Dry particles like lead or asbestos are stopped by this fabric, which makes these affordable garments popular for construction, painting, and insulation installation jobs. It allows water vapor to permeate, which makes it breathable and comfortable, but still offers some protection against liquids. However, for jobs or projects where chemical splashes and other highly hazardous liquids will be present, more expensive and more elaborate safety gear is a smart choice.

One of the nicest things about these garments is that they are inexpensive enough to be disposable. Instead of the worry of laundering and handling coveralls after they have been exposed to dangerous materials, you can simply throw the worn items away. This reduces risk of harm for everyone on your team.

This material, while developed for safety wear, has other uses as well. Fashionable retailer American Apparel sells shorts made of this textile to its youthful audience of stylish shoppers. Rock band Devo, known for their avant-garde music and sensibility, have been spotted wearing this material in their stage shows and music videos. Because the material is so unique and modern, its visual appeal to fashionistas takes it beyond its original purpose on job sites.

Why does it matter that this is such a high density material? Because the strength of the textile means it is difficult to accidentally rip or tear. While it can be deliberately cut with scissors or a blade, it is almost impossible to snag or damage without meaning to, so wearers can be assured of safety, and won't be surprised by a vent in their protective layer of outerwear.

The company that produces this unique fabric, DuPont, has instituted a program of recycling. If a Tyvek garment or object, like a United States Priority Mail envelope, has been used but has not been exposed to hazardous materials, the company will accept it and reprocess the disposable item anew. This makes it a relatively eco-friendly synthetic material.
