Eastman debuts flat PET fibre for wetlaid nonwovens
September 06, 2014 - United States Of America
New product possibilities are on the horizon for manufacturers of wetlaid nonwovens and specialty papers with the addition of a flat PET fiber to the Cyphrex microfibers portfolio at Eastman Chemical Company.
The flat PET Cyphrex fibers which are less than 0.4 denier in size with their novel cross section, enable functional benefits such as uniformity, lightweight strength and improved processing compared with other synthetic microfibers, Eastman informs
With its distinctive, consistent cross section, the flat PET microfiber greatly improves nonwovens formation and sheet uniformity when compared with other synthetic fibers and offers functional benefits in applications, for which dimensional consistency within and across the nonwoven is critical, the fibre producer adds.
Eastman adds, “In addition, the flat PET fiber provides greater lightweight strength in nonwoven media. Compared with other synthetic fibers, flat PET fibers enable impressive tensile, tear and burst strength within a very lightweight nonwoven sheet, as well as outstanding green strength.”
“In some applications, these fibers can also improve strength-to-weight ratio and dimensional stability”, it claims.
“By offering round and flat fibers, nonwovens producers can more precisely manufacture media to fit their customers’ needs, giving them an advantage in formulation capability”, says Fred Dulin, Director, Microfibers platform at Eastman.
Since, flat PET microfibers disperse easily in water; they are compatible with standard wetlaid and papermaking processes and equipment and do not require special shear or agitation and also allow easy blending with a broader range of fibers.
“The flat PET fiber is part of our ongoing effort to create and give our customers innovative microfibers that fit their specific needs,” Dulin said. “This is the latest example of how Cyphrex can keep creating new possibilities for wetlaid nonwovens manufacturers.”
US-based Eastman Chemical serves customers in around 100 countries, posted revenues of around $9.4 billion in 2013 and employs approximately 14,000 people around the world. (AR)
