Introducing T859 LYCRA
HyFit® fiber

T859 is our latest commercial fiber. T859 offers a lower consumption rate, supply chain savings and operating efficiencies that align with our hygiene customers’ sustainability goals. It will result in an overall more environmentally friendly product offering and a smaller carbon footprint. With T859, we have changed a key raw ingredient of the polymer so that the retractive force per decitex is higher than previous product offerings. This polymer upgrade enables lighter decitex T859 products to replace heavier weight materials. For example, 600 dtx T859 may be used in place of 800 dtx T837. A patent application has been filed for this new polymer formulation.



Results of numerous trials at equipment makers and diaper producers have validated the decitex reduction in both laminates and finished diapers.

Current T837 Decitex New T859 Decitex Percent Decrease
800 600 25%
680 530 22%

The table above contains two examples of the relationship between our current T837 product offering and our new T859 fiber.

Lighter decitex replaces heavier decitex to deliver more meters per kilogram of fiber, which results in longer package run time with fewer package-to-package transfers. This should increase diaper line uptime, reduce product handling and boost overall savings.

By converting to T859, you’ll also benefit from a significant reduction in elastic consumption per unit while continuing to achieve similar stretch and recovery.
