LYCRA® DUALFX® technology

dualFX

The leading solution for performance denim and wovens with super stretch and recovery

Why choose LYCRA® dualFX® technology?

The challenge:

As fabric stretch increases, so does the tendency for fabric growth or shrinkage. This can negatively impact garment performance and lead to poor fitting jeans that don’t hold their shape, product returns, and dissatisfied consumers.

The solution:

Patented LYCRA® dualFX® technology consists of two stretch fibers - one spandex (elastane) and the other polyester bi-component fiber - that create denim with unmatched performance. LYCRA® fiber provides durable stretch for comfort and fit, while the LYCRA® T400® fiber provides bounce-back recovery for exceptional shape retention. These fibers are put together and covered with cotton to achieve an authentic denim look and feel, while offering extra flexibility, all-day comfort and lasting fit.

Testimonial

Voice of the expert

"At The LYCRA Company, we believe in continuous improvement and are always working hard to make our products even better. When we learned from our customers that they were having tremendous issues with high stretch fabrics, we said “How can we make this better?” We worked with our customers to prove out our hypothesis that adding LYCRA® T400® fiber into the yarn could really make a difference. The resulting product has truly revolutionized denim."
