Soft structure Type 14 is soft, fabric-like and drapeable. Sewing, gluing and, to a limited extent, ultrasonic seaming and heat sealing, may be used in fabricating these styles. Type 14 styles are used where barrier, durability and breathability are required. They offer excellent barrier against particulate matter and can provide an excellent bacterial barrier. The unique low-linting properties, combined with the barrier properties, make Type 14 an excellent material for cleanroom garments and pharmaceutical manufacturing garments.

Q29: Can Tyvek® be laminated? Will the process affect water resistant performance and breathability? Tyvek is best known as a weatherproof house wrap. It’s that white, papery stuff you’ve probably seen on the sides of unfinished buildings – though its all-around bad-assery is deployed seemingly everywhere. Those hooded, hazmat-esque garments that have made a fashionable appearance during COVID times? Tyvek. The crinkly, white priority mail envelopes from the USPS? Tyvek! Race bibs? Concert bracelets? (Remember concerts?) Those “world’s thinnest” and “world’s strongest” wallets? Whenever the world needs something cheap, rainproof, lightweight, and durable, Tyvek is there.A: Ironing is not recommended, because the heat of the iron will melt or damage Tyvek®, Tyvek® melts at 135°C. Made of high-density polyethylene fibres (HDPE), Tyvek® is 100% recyclable just like plastic bottles. Costa Rica (solely their 20 colones bank note, Z series), [17] the Isle of Man, [18] and Haiti [19] have made banknotes from Tyvek. These banknotes are no longer in circulation and have become collectors' items. As plastic bag recycling has become more prevalent in the United States, the American Chemistry Council has recommended that plastic film drop-off recycling locations should be able to accept Tyvek. [9] Properties of Tyvek [ edit ] That said, on my own soggy, northbound AT hike, the off-brand variety I used as a groundcloth started to soak through during the first few hundred miles. I switched it out for a seemingly more robust Tyvek-brand sheet in Erwin, Tennessee, and fared just fine for the rest of my hike. Is Tyvek really breathable?

A: Yes. Water-based adhesive, solvent adhesive, animal glue, hot melt adhesive and so on can be used for Tyvek® gluing. When selecting an adhesive, consider the composition of the materials to be glued, the processing conditions, and the end-use conditions. Some adhesives contain ingredients (such as plasticizers, solvents, or monomers) that can distort Tyvek®. Work with your adhesive supplier to select and thoroughly test the adhesive for your application, before beginning mass production.
