The Austria-based Lenzing Group recently sent Murata Machinery Ltd., Japan, a letter of thanks for
Murata’s Vortex spinning machine and its contribution to the development of cellulose fiber yarns.
An examination of the machine and Murata’s commitment to the development of regenerated cellulose
fiber yarns led to a consensus of opinion that a cooperative technology relationship should be
established for the spinning of regenerated cellulose fibers.

In particular, the letter mentioned Murata’s contribution to the success of Ecosil yarns by
Korea-based Samil Spinning. The yarns are spun on Vortex machines using Tencel®, Lenzing Modal® and
Lenzing Viscose® fibers, among other Lenzing regenerated cellulose fibers. The three companies
worked in cooperation to develop the yarns, studying raw material choice and blending and drafting
ratios to create the optimum product. Vortex production gives the yarn resistance to pilling and
minimizes knit material shrinkage and torsion, according to Murata.
The letter of thanks was cosigned by Fritz Weninger, vice president, Lenzing Group Textile
Fibers business unit, and Dieter Eichinger, global marketing director, Textile Fibers.
