Zetix is a fabric invented by Auxetics Technologies, Ltd., a UK company. It is marketed in North America under the trade name Xtegra by Advanced Fabric Technologies of Houston, Texas.
Zetix is an auxetic material that is so strong it absorbs and disperses the energy from explosions without breaking. Zetix combines the very expensive high-performance materials with cheaper bulk components in a 1-to-100 ratio while maintaining the blast-resistant properties of the high-performance materials.
Usage
Zetix is used in a variety of products including body armor, seat belts, window covering, dental floss, military tents, hurricane defenses and medical sutures that will not damage body tissue. It also has some very interesting applications in composite materials.
Zetix is also used in threads and ropes. Knots under tension may be more secure because auxetic material expands when stretched.
