Why Choose LYCRA® dualFX® Technology?

Sep 03, 2019

The problem: 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 that deliver unmatched performance in denim. 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 intermingled together and covered with cotton to achieve an authentic denim look and feel, while offering extra flexibility, all day comfort and lasting fit.
