The Yarn for Winners –
PTFE Cooperation Project with Lenzing Plastics and Pforzheim University

"Sharing the textile future together" – that's the slogan of the Technology and Development Center (TEZ). Not only machine builders, users, textile producers and scientific institutions are welcome project partners here, but also academies and universities. One current example is the cooperation project between Lenzing Plastics GmbH and Pforzheim University.

The background: Innovative yarn, intelligent cooperation

The main headquarters of Lenzing AG in Lenzing
Pforzheim University

Lenzing Plastics GmbH is a subsidiary of Lenzing AG, Austria, and one of the world's leading manufacturers of products made from polyolefins and fluoropolymers. The PTFE (polytetrafluoroethylene) division of Lenzing Plastics GmbH developed a wire sheathed in PTFE for specific technological applications. To find new areas of application for this yarn, the Fashion study course at Pforzheim University organized a student competition. Eight highly motivated female students took part in it.

The task: New fields of application, tangible benefits

Perfect working conditions...
... in the Technical Center Knitting at the TEZ.
Every one of the students...
...worked hard and happily.

Dimensional stability and strength on the one hand – and resistance to chemicals, ultraviolet light and temperature, ultra-low friction and clean surfaces on the other. The "Lenzing PROFILEN© PPW" yarn developed by Lenzing Plastics combines the properties of wire with those of PTFE yarn.

Under the supervision of Ms. Kerstin Nägler-Bothner, lecturer in concept knitting, and study course director Professor Johann Stockhammer, the eight students who took part were now faced with a complex task. Their job was to find new applications in which the abovementioned properties could be put to optimum use. The focus was primarily on technical textiles, which is why the applications were not exclusively fashion-related.

In cooperation with their professor, the students developed concepts that were all based on knitted fabrics. This is where the Technology and Development Center (TEZ) entered the picture. For implementation of the concepts, Groz-Beckert allowed the students to utilize the Technical Center Knitting in the TEZ, as well as the services of experienced knitting specialists. The enthusiastic students took full advantage of this opportunity in groups of two and three, and spent a busy and exciting day in the TEZ – with expert discussions, practice-based problems, and new insights into the textile industry.

The result: Eight concepts and a win-win situation

The Flowerpot by Stefanie Stohwassers
The "Lawn or Flower Mat" by Alexia Stohler
The knit by Verena Lehner
The winner of the competition – the illuminated 'hanging seat' by Konstanze Blickle

The students adopted the most diverse approaches:

  • Ms. Maria Fernandes dos Santos developed a cape that acted as a protective cover.
  • Ms. Damaris Moos created a multiple-use beach mat.
  • Ms. Stefanie Stohwassers produced a flowerpot made of "Lenzing PROFILEN© PPW"
  • Ms. Alexia Stohler was inspired by the trend of "city gardening" and developed a portable "Lawn or Flower Mat”.
  • Ms. Heike Hilpert contributed a folding origami tent.
  • Ms. Verena Lehner modeled a fabric in plissé form (made of "Lenzing PROFILEN© PPW"), and this generated a great deal of interest in terms of its potential architectural applications.
  • Ms. Selina Friedmann invented a global raft concept which gained much positive feedback as a marketing impulse.
  • Ms. Konstanze Blickle impressed the jury at Lenzing with her illuminated hanging seat, and was pronounced the winner of the competition.

Well received

On July 13 and 14, as part of an exhibition at Pforzheim University, the developments were presented to a broad public and met with a very positive reception. The competition has proved how innovations from the industry and the inexhaustible creativity of young junior employees can result in magnificent synergies. Groz-Beckert is proud of having supported this project by supplying know-how, machinery and equipment.

Here's what those involved in the project had to say about it:

Ms. Kerstin Nägler-Bothner: "We were really impressed by the machinery in the TEZ. Without the support of Groz-Beckert we wouldn't have been able to implement the concepts in this form. Thanks very much!"

Professor Johann Stockhammer: "It was very interesting to get a direct insight into the industry, with so much stimulating input. We were especially impressed by Groz-Beckert's quality awareness."

Ms. Stefanie Stohwassers, on behalf of all those who took part in the competition: "The project was definitely a very interesting and very exciting experience. We'd definitely be interested in taking part in a similar project anytime."

Mr. Volker Biladt, Marketing & Sales Director, Lenzing PROFILEN© PPW: "Of course we were aware that our new yarn offers huge potential – but the sheer variety of these first-class application concepts and their implementation still surprised us greatly. We're more than satisfied with the project."
