Invista & Lenzing to add aesthetics to stretch fabrics

By combining INVISTA’s patented LYCRA dualFX fabric technology with LENZING’s TENCEL fibre, the two companies are delivering a unique solution to the industry: cellulosic denim fabrics with significantly improved shape retention.

According to Federica Albiero, INVISTA’s Denim Account Manager for Southern Europe, about a year ago INVISTA began hearing about the challenges its mill customers were facing in developing stretch cellulosic fabrics. The company initiated a study to identify the underlying mechanisms of these issues and determine how to improve them.

“Given the growing popularity of both LYCRA fibre and TENCEL fibre in the denim market, it was only natural that people wanted to combine them to come up with really amazing fabrics”, Albiero said. “However, as mills began experimenting they encountered issues such as growth, fabrics not keeping their shape, and fabric puckering due to seam slippage.”

To address these issues INVISTA looked to its LYCRA dualFX fabric technology, which combines two stretch fibres – LYCRA fibre and LYCRA T400 fibre – into a single yarn. INVISTA ran trials pairing this technology with blends of cotton and TENCEL fibre.

The trials showed significant improvement in fabric recovery and slippage to the point where the fabric performance met or exceeded INVISTA’s and the industry’s standards. From there, INVISTA and Lenzing decided to work together to promote these fabrics in the marketplace.

Lenzing is pleased to work with INVISTA to help our customers develop commercial fabrics with strong marketing attributes. Both companies have global sales, marketing and technical teams supporting the developments and they will provide joint promotional materials as well as supply chain support and marketing information.

“This initiative represents two globally innovative fibre companies working together to provide the denim market with fabrics that meet the performance needs of modern consumers”, says Michael Kininmonth, Senior Project Manager of Denim at Lenzing Fibres Inc. “Superior comfort with stretch and long-lasting recovery are set to become the next core product in women’s wear.”
