Cyphrex reinvents paper performance

These microfibers can be run at standard consistency (1.0 percent to 3.2 percent) on the wet end, disperse easily with minimal sheer and can blend with cellulose to improve strength and formation of paper products.

Another benefit is that Eastman Cyphrex™ microfibers can be easily run as 100 percent of the fiber furnish on conventional papermaking machinery and can be processed very much like cellulose on flat wire machines, a benefit not typically expected from synthetic fibers.

An improved synthetic Overall Cyphrex microfibers improve strength, formation and permeability of high-strength paper products — without requiring significant processing compromises.

These microfibers, too, can be converted to nonwoven substrates without the processing and performance tradeoffs often observed when incorporating existing synthetic fibers. Eastman Cyphrex™ microfibers provide excellent wet strength, they can be run at standard consistency on the wet end and they provide high dry strength without the use of a wet strength agent or bonding agent; they do, however, respond exceptionally well to wet strength agents when those materials are used.

Ideal for papermakers “Eastman Cyphrex™ microfibers are well-suited for paper, pulp and nonwoven industry technical professionals who want innovations that can help them stay ahead of product commoditization,” said Jon Woods, general manager, nonwovens microfibers, Eastman. “Because technical professionals want synthetic fibers to enable product performance without the processing challenges that often accompany them, Cyphrex microfibers could enable new attributes to allow for more customizable applications in the high-strength paper applications.”
