Invista, one of the world’s largest integrated producers of polymers and fibers, and owner of the Lycra HyFit brand for the hygiene industry, and Aurizon Ultrasonics, a leading supplier of ultrasonic processing equipment to the hygiene industry, are cooperating on a new joint development project. This project will focus on the collective development of novel ultrasonic bonding equipment and innovative stretch fibers for the construction of stretch laminates, without the use of hot melt elastic attachment adhesives. The desired outcome of this collaboration is a step-change advancement allowing hygiene producers to improve product fit and comfort without the cost and complexity of glue.
 
“Invista is excited to explore the combination of Aurizon’s cutting edge capabilities in ultrasonic bonding with our market leading research and development team that has delivered continuous innovations to our Lycra HyFit fiber offering,” says Scott Blackadar, global vice president, Invista. “We believe that step change innovations in diaper design and cost reduction will result from this joint effort.”
 
“We are thrilled to join efforts with Invista, the market leader in stretch fibers, to further advance next generation stretch materials for the hygiene market,” says Greg Benrud, Aurizon president. ”Aurizon’s current technology to ultrasonically secure elastics in nonwovens without the need for adhesives can enable lower material costs, increased operational efficiency, and improved product comfort and performance. We believe this collaboration will provide an opportunity to leverage the strengths of both companies and accelerate further development of exciting new materials and processes for our customers.”
 
Blackadar adds, “We look forward to collaborating with Aurizon and discovering the potential synergy between our new fiber innovations and Aurizon’s high speed rotary ultrasonic bonding technology.”
