Tyvek® Soft Structure / Tyvek® Fabric

 

Tyvek® Soft Structure is part of a family of tough, durable sheet products used in a variety of applications. Tyvek® Soft Structure is often referred to as Tyvek® fabric because of its fabric-like texture. Tyvek® Soft Structure is designed specifically for applications where drape, hand, and soft feel are of prime importance. Made from very fine high density polyethylene fibers, Tyvek® offers all the best characteristics of paper, film, and fabric in one material. This unique balance of properties, which cannot be found in any other material, makes Tyvek® Soft Structure fabric lightweight yet strong. It is vapor-permeable, yet water-, chemical-, puncture-, tear-, and abrasion-resistant. Available products include Type 14 (Style 1443R, Style 14-S metalized) and Type 16 (Style 1622E). Tyvek® Soft Structure is also low-linting, smooth, and opaque. Tyvek® meets all the requirements of the USA Flammable Fabrics Act, CA-191-53, for wearing apparel* and is widely used in edgy fashion designs.

Uses of the Tyvek

 

 

 

 

 

Large sheets of Tyvek are frequently used as "housewrap," to provide an air barrier between the outer cladding of a structure and the frame, insulation, etc., allowing water vapor to pass yet restricting air infiltration.

 

Tyvek is used by the United States Postal Service for some of its Priority Mail and Express Mail envelopes. New Zealand used it for its driver's licenses from 1986 to 1999,[6] and Costa Rica, the Isle of Man,[and Haiti have made banknotes from it. These banknotes are no longer in circulation and have become collectors' items.

 

 

 

Tyvek coveralls

 

 

 

Tyvek coveralls are one-piece garments, usually white, commonly worn by mechanics, oil industry workers, painters, insulation installers, and laboratory and cleanroom workers where a disposable, one-time use coverall is needed. They are also used for some light HAZMAT applications, such as asbestos and radiation work but do not provide the protection of a full hazmat suit. Tychem is a sub-brand of Tyvek rated for a higher level of liquid protection, especially from chemicals. DuPont makes Tyvek clothing in different styles from laboratory coats and aprons to complete head-to-toe coveralls with hoods and booties. The latter was notably used by the Japan Ground Self-Defense Force as emergency limited CBRN gear during the Fukushima nuclear incident.

 

In 1976, fashion house Fiorucci made an entire collection out of Tyvek. More recently fashion retailer and manufacturer American Apparel has included white Tyvek shorts as part of its range Rock band Devo is known for wearing large, two-piece Tyvek suits with black elastic belts and 3-D glasses. In 1979, Devo appeared with Tyvek leisure suits and shirts made specifically for the band, with the band's own designs and images.In 2005, Dynomighty Design ntroduced a Tyvek wallet made from a single sheet of Tyvek. The ultralight backpacking community has begun to use Tyvek for the construction of extremely light yet durable backpacks.In 2012, The Open Company released a foldable city map made of one of the stiffer variants of Tyvek

 

Increasingly, reused Tyvek material is being used by home crafters. Protective sleeves for Compact Discs and DVDs, tote bags,and origami wallets also use Tyvek-containing materials.

 

Tyvek is also used as a durable fabric in shoes.

 

Tyvek is used in archery to construct waterproof target faces, replacing paper.

 

Tyvek is also extensively used for packaging in laboratory and medical equipment as the material withstands conditions used to sterilize equipment

 

Tyvek wristbands are used at festivals, conventions, and events where admission and security are concerns,as well as hospitals, resorts, nightclubs, schools, and reunions.

 

 

 

Tyvek was used to cover and protect the Reaction Control System (RCS) thruster ports from water and debris while the shuttle stack was exposed on the launchpad during the latter years of the Space Shuttle program.[The Tyvek covers were dislodged shortly after ignition and before the shuttle cleared the tower, posing no strike risk as the shuttle was travelling below 100 MPH
