The appeal of denim has grown steadily over the last two decades. Its initial transition from heavy duty work wear to universal popularity in the 1960s revolutionized casual wear for both men and women. But the products of the time were less than ideal – traditional men’s jeans were heavy and stiff; on the women’s side even lighter weight variants were rigid. And all tended to bag and sag with regular use.

That was yesterday. Since then, unique LYCRA® technologies have enabled enterprising mills to develop a new generation of high-tech denim fabrics. Designers and brands have seized the opportunity to combine stylish looks with comfort, fit and freedom of movement. The world’s most popular garment is now more versatile than ever, with looks ranging from ultracasual to urban chic.

Thanks to an ongoing commitment to innovation, INVISTA has developed technologies to help consumers solve their most pressing denim dilemmas.  Our dualFX® technology by LYCRA® brand allows consumers to have super stretchy jeans that really do keep their shape, negating the bag and sag traditionally associated with high stretch fabrics. XFIT technology by LYCRA® brand provides moderate stretch in all directions so wearers can experience 360 degree comfort in wear. Fabrics with TOUGH MAX™ technology by LYCRA® brand bring new performance to the rugged end of the denim marketplace. Thanks to the use of LYCRA® T400® fiber, now jeans can be both durable and comfortable to wear. And jeans with lastingFIT technology provide comfort stretch with recovery that never quits.

Woven Fabric Technologies


LYCRA® dualFX® technology

LYCRA® dualFX® technology brand was developed in response to market demand for high-stretch denim fabrics that keep their shape. It is based on several patented technologies from INVISTA related to dual core yarns and bi-component yarns.

Typically, as fabric stretch increases so does the tendency for fabric growth or shrinkage. By combining LYCRA® fiber and LYCRA® T400® fiber together in one fabric, you get the best of both worlds — the high stretch of LYCRA® fiber and the excellent recovery power of LYCRA® T400® fiber.
