How Xtegra™ Works
Stretch a bungee cord and it gets thinner. But wrap a string around it and stretch‚ and it gets effectively wider. Weaving these wrapped cords into bundles creates an Auxetix Structure that thickens when subjected to explosive forces.
Auxetic Fabric Design Principle
The performance of Xtegra™ in ballistic curtain and tent applications is directionally dependent, meaning that the length of the curtain or height of the tent is equivalent to the width of a roll of Xtegra™ fabric.

- The HAY is a fiber structure comprised of two components,
- HAY fiber structure: One fiber is helically wrapped around a core fiber
- Under tension, the wrap tends to straighten causing the core to displace laterally in a helical manner
HAY fiber structure unloaded.

If the wrap fiber is of a lower diameter than the core this behavior can result in a net increase in the effective diameter of the composite
Yarn - a negative Poisson’s ratio.
Successful blast tests have been conducted by the UK Ministry of Defense. Additional blast and ballistic tests are under way on a variety of fronts. Results and test photos and videos will be posted on this Web site as they become available.
Xtegra™ is the only blast-mitigation fabric on the market that stops shattered glass and metal shrapnel and other flying debris from an explosion.
Xtegra™ won awards in the Global Security Challenge European Semi-finals (2007 & 2009), has been cited for Business Excellence and Innovation by the Performance Textiles Association, and received TechTextile's 2007 Innovation Prize.
