Tyvek
Tyvek /taɪˈvɛk/ is a brand of flashspun high-density polyethylene fibers, a synthetic material; the name is a registered trademark of DuPont. It is often seen used as housewrap, a synthetic material used to protect buildings during construction. The material is very strong; it is difficult to tear but can easily be cut with scissors or a knife. Water vapor can pass through Tyvek, but liquid water cannot. All of these properties make Tyvek useful in a variety of applications.
History
Tyvek is a nonwoven product consisting of spunbond olefin fiber. It was first discovered in 1955 by DuPont researcher Jim White who saw polyethylene fluff coming out of a pipe in a DuPont experimental lab. It was trademarked in 1965 and was first introduced for commercial purposes in April 1967.
According to DuPont's website, the fibers are 0.5–10 µm (compared to 75 µm for a human hair). The nondirectional fibers (plexifilaments) are first spun and then bonded together by heat and pressure, without binders.
