Eastman Launches Microfibers Platform

April 25, 2013

Cyphrex microfibers unlock unlimited possibilities for product performance, quality and value for specialty nonwovens.

Eastman Chemical has launched the new and innovative Eastman Cyphrex microfibers at IDEA13. These microfibers offer tunable fiber properties of size, shape and material that provide the wet-laid nonwoven producers with advantages that aren’t currently available says the company. The microfibers have demonstrated nearly drop-in compatibility with existing wet-laid nonwoven processes. Cyphrex microfibers have the potential to be used in such markets as air, water or fuel filtration; specialty papers; and battery separators.

“The technology behind Eastman Cyphrex microfibers and the functionality it enables is unique and revolutionary, unlike anything else on the market,” says Mark Costa, executive vice president, Eastman Chemical Company. “These microfibers unlock possibilities that provide innovation in the nonwovens marketplace by allowing cost-effective access to a previously unavailable size range of highly uniform synthetic fibers. Consequently, we believe these new possibilities will result in breakthrough product performance, quality and value for specialty nonwovens.”

Eastman has invested in growing its application development expertise to help address specific customer and market needs. This experience, combined with the capability to manipulate the size, shape and material of Eastman Cyphrex microfibers, enables what it says are market-changing solutions for a new level of performance.

Eastman Cyphrex microfibers, which are less than 5 microns in diameter, deliver a high surface-to-mass ratio and offer a narrow diameter distribution. They provide optionality of fiber cross-sections in shapes such as round, flat and wedge. The fiber material can consist of different polymer types, such as PET, PP and nylon, and has consistent properties that enable new formulations and design flexibility.

The ability to customize size, shape and material offers functional and competitive advantages for nonwovens media in areas such as strength, uniformity and targeted permeability.

“To satisfy challenging industry needs, the technology behind Eastman Cyphrex provides a revolution in microfibers,” says Fred Dulin, director, microfibers platform, Eastman Chemical Company. “Our innovation allows precise, consistent and unique fiber designs that are thoughtfully and purposefully created for varied applications across numerous markets.”

Eastman has long had an investment in research and development and manufacturing for many successful products. To support the Eastman Cyphrex microfibers, at its Kingsport, TN, headquarters, Eastman has a world-class synthetic fibers developmental spinning line as well as a nonwoven and specialty paper research lab.
