Ready, Set, Stretch: Denim With Attitude

When it’s deliver-or-die, supply chains become the lifeblood of a company. To that end, the fashion industry has embraced technology to navigate today’s hyper-complicated supply chain, with myriad solutions shaping the first, middle and last mile. Call it Sourcing 2.0.

Lubrizol’s innovative fiber, X4zol™-J, takes denim fit to a new frontier with balanced, 360-degree comfortable stretch and support.

Wearers feel energized in denim fabrics containing X4zol™-J, allowing them to move comfortably and confidently in different climates, while it retains that “newness”
from wash to wash.

The Lubrizol Corporation, a Berkshire- Hathaway company, has engineered a thermoplastic polyurethane (TPU) fiber that revolutionizes denim fabric, as well as other fabric types. X4zol™-J is a unique elastomeric monofilament that is both finer and stronger than traditional spandex, and is manufactured without solvents.

The flat modulus of the X4zol™-J fiber allows the denim to stretch more easily and doesn’t feel restrictive, yet it provides support. Denim containing X4zol™-J shapes and sculpts different body types into a smooth silhouette, without the feeling of being restricted, so the wearer experiences the ultimate in comfort. This makes it ideal for different body shapes and sizes. Additionally, X4zol™-J requires at least 30 percent less force to stretch than spandex. The fiber is produced using a melt extrusion process. The resulting monofilament has significantly higher molecular weight vs spandex, making it both thinner and stronger. This translates to a higher breathability in denim fabrics creating a cooling sensation. X4zol™-J is produced without the use of solvents common in other stretch fiber production resulting in a reduced environmental impact*.

Lubrizol collaborated with Olah Inc., a New York-based denim marketing company with global experience, to develop denim fabrics with Prosperity Textiles to supply to brands and retailers. Olah Inc., in combination with Prosperity, has provided the technical expertise to create the next generation of stretch denim fabrics with attributes targeted to consumer demand. Other denim mills will join the Olah team with X4zol™-J in the future.

Michael Morrell, a partner at Olah Inc. believes, “X4zol™-J is the only true sculpting fiber because of its linear compression traits which are so essential to stretch jeans.”

“The secret to the success of X4zol™-J is in its very nature,” says Michael. Traditional elastane stretch fibers feature a steeper stress/strain curve, illustrating initial resistance to stretch, and then finally a rapid increase in resistance to the point of full elongation, or breakage. A compelling attribute of X4zol™-J is its distinctive stress/strain curve, which illustrates softer, more consistent stretch up to the point of full elongation, tracing a “J” shape. This allows the wearer to experience freedom of movement with no restriction.

Olah’s partner mill, Prosperity Textiles, will feature the Fall 2018 collection of denim garments made with X4zol™-J under the “J-Fit” trademark at the Amsterdam Kingpins Show April 19-20 and at the Paris Denim Premiere Vision Show April 26-27, 2017.
