Technical Overview
Dukane’s Curved Leg Elastic (CLE) technology introduces a breakthrough method for attaching elastic strands with ultrasonic bonding—completely eliminating the need for hotmelt adhesives. This delivers a cleaner, more efficient, and more reliable process for modern nonwoven applications.
Building on Dukane’s patented elastic attachment technology, CLE enables manufacturers to combine curved and straight elastics within a simple two-layer nonwoven panel. This innovation improves product performance, reduces material complexity, and provides greater design flexibility while maintaining consistency and repeatability in high-volume production.
Design Freedom: CLE allows easy adjustment of strand spacing by changing the infeed roll, eliminating spray nozzle limitations. Side seams become more discrete, aesthetics improve, and gathering effects can be tailored.
Consistent Performance: Bonds remain secure at both ambient and extreme “boxcar” shipping temperatures, ensuring reliable strand attachment and long-term durability.
With CLE, manufacturers deliver softer, more breathable, and more comfortable products while streamlining operations and reducing waste.
