Product development involved intensive R&D work, and Zschimmer & Schwarz held discussions with nonwoven producers, industry organizations and consumer goods producers to evaluate the requirements for a new product in this field. "The bottom line in all these discussions was that a new product should 'have it all,'" the company said.
"The focus for the team working on this development was to come up with a product that is of course fully [Food and Drug Administration] compliant and has an unrivaled safety background as well as a superior technical performance," Zschimmer & Schwarz explained. "The work started with laboratory scale formulations of the finish itself, followed by small scale applications to fabrics. The next step after this initial phase was the application of the new finish using the nonwoven treatment pilot line at Zschimmer & Schwarz Centre of Fiber excellence in Lahnstein, Germany."
