INVISTA and Lenzing are teaming up to improve performance of denim
INVISTA, owner of LYCRA® fibre, and Austrian Lenzing, a leading producer of man-made cellulosics like rayon, modal, and lyocell, are teaming up to bring improved aesthetic performance to stretch fabrics
The principle of the cooperation is through combining INVISTA’s patented LYCRA® dualFX® fabric technology with LENZING’s TENCEL® fibre, thus the two companies will deliver a unique solution to the industry: cellulosic denim fabrics with significantly improved shape retention.
The reason for this collaboration: INVENTA recognised the challenges its mill customers were facing in developing stretch cellulosic fabrics. Thus, the company initiated a year ago a study to identify the underlying mechanisms of these issues and to determine how to improve them.
According to Federica Albiero, INVISTA’s Denim Account Manager for Southern Europe, states: “Given the growing popularity of both LYCRA® and TENCEL® fibre in the denim market, it was only natural that customers wanted to combine them to come up with really amazing fabrics. 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 investigated its LYCRA® dualFX® fabric technology, which combines two stretch fibres (LYCRA® fibre and LYCRA® T 400®) into a single yarn. INVISTA ran trials by pairing its technology with blends of cotton and TENCEL® fibre. The trails 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. This was the decisive point for INVISTA and Lenzing to promote these fabrics in the market place.
Recently, TENCEL® fibre has been reinvented by denim designers as perfect complement to today’s fashion trends. Jeans with TENCEL® fibre are attractive and lasting. They become immediate favourites to their enhanced comfort. The fibre’s smooth surface and optimal moisture transfer benefits turn jeans into articles of clothing that enhance physical well being and at the same being trendy. The revival of TENCEL® fibre in denim has also an environmental aspect, because it results in a significant improvement, because the fibre is made from wood growth in sustainably managed forests. In addition the production process for TENCEL® fibre is based on a closed loop solvent spinning process.
INVISTA introduced its LYCRA® dualFX® fabric technology around two years ago. Initial applications were with cotton bringing improve shape retention to denim fabrics, particularly to super stretch styles difficult to control using standard core spun yarns. Now the same benefits can be realised in fabrics with TENCEL®, offering a wide palette of new applications and styles.
