Eastman expands Cyphrex range

February 6, 2014

Blending microfibers helps achieve precision, consistency.

In response to the nonwovens market’s need for expanded formulation options with fine fibers, Eastman Chemical Company is enhancing its platform capability with a 4.5-micron diameter PET microfiber, specifically designed for wetlaid processing. This addition to the family of Eastman Cyphrex microfibers comes less than a year after the successful launch in April 2013 of its commercially available 2.5-micron diameter microfiber. When blended, the company says these highly uniform microfibers can allow the formulator to help pinpoint permeability and control pore size, resulting in greater precision for targeted functionality.

The introduction of this larger, 4.5-micron (0.2-denier), round PET fiber opens up the space formulators can access with regard to targeting specific pore sizes and desired permeability in their media, making it a highly suitable material for filtration applications. In addition, it opens more possibilities for manufacturers, and can provide even better formation, or sheet uniformity, when compared with the 2.5-micron (0.06-denier) fiber.

Eastman says its Cyphrex microfibers offer a unique combination of capability in variation of size, shape and material, a high level of uniformity and consistency, and ease of wetlaid processing. This combination opens new possibilities to nonwovens formulators and their customers in achieving an expanded reach of desired properties with a high degree of precision and consistency.

“The new 4.5-micron fiber demonstrates our capability of changing size, and manufacturers can use this unique fiber to pinpoint permeability and pore size and to improve media uniformity even further,” says Fred Dulin, director, microfibers platform, Eastman. “These results demonstrate that significant value can be created in nonwoven formulations through specific design of fiber size characteristics and insights provided by industry-standard application development capabilities.”
