Zschimmer & Schwartz Unveils Lertisan HD 50

Zschimmer & Schwarz, Germany, a manufacturer of spin finishes and additives for fiber and nonwovens applications, reports its Lertisan HD 50 additive for the manufacture of durable hydrophilic nonwovens offers superior characteristics compared to products currently used for such applications.

According to the company, advantages include a simplified emulsion preparation and improved emulsion stability, simplified application, and superior durable hydrophilic properties. 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."
