Andreas Wilhelm Gürtler is Head of Global Business Development for the Lenzing Group. Lenzing is responsible for developing the unique fiber known as TENCEL®, which is derived from the wood pulp of sustainably farmed eucalyptus trees. Icebreaker harnesses the power of TENCEL® in Cool-Lite™, a fabric innovation that combines the next gen fiber with New Zealand merino wool with outstanding results.
Cool-Lite™ clothing is designed for anyone who is looking for high performance natural alternatives to synthetic fabrics and cares about the impact their clothing has on the environment. Andreas is a fountain of information when it comes to why TENCEL® is such an essential fiber to ensure the future of our planet, and why it’s such a great choice for the modern adventurer.Tell us a little about the Lenzing Group…
We’re based in Lenzing, Austria and started out as a paper mill. Now the Lenzing Group supplies the global textile and non-wovens industry with high-quality, botanic cellulose fibers – viscose, modal and TENCEL®. We’re the only company worldwide combining the manufacturing of all three cellulose fiber generations on a large scale under one roof. We employ over 6000 people worldwide.What is the philosophy at the heart of Lenzing?
We like to think we’re leaders in the fields of innovation, technology and quality. Lenzing is committed to the principles of sustainable management and very high environmental standards. We buy the trees we turn into wood chips, which become pulp and eventually, fiber. Only 40 per cent of the tree is actually used for fiber production. We then take an extra 10 per cent – made up of by products – for use in the food and oil industries. The other 50 per cent – resin, bark from the trees and the like – we incinerate in an environmentally friendly way. This means we are independent of fossil fuel and use natural energy for our engines and plants. We don’t need it to drive our company. In addition, our water treatment plant is so big that if needed, it could treat water for a community of one million people.
“No other man-made fiber today can be produced in such a sustainable way, and unlike polyester, TENCEL® dissolves completely in the ocean so is of no threat to marine life.”
First of all, TENCEL® is produced via a surprisingly simple physical, as opposed to chemical, production process. It’s basically created with water, a non-harmful solvent and wood pulp, and the wood is sustainably sourced eucalyptus from forests in Austria and our neighbouring countries. No other man-made fiber today can be produced in such a sustainable way, and unlike polyester, it dissolves completely in the ocean so is of no threat to marine life.What are the key benefits of TENCEL® to the consumer who lives a life in nature and looks for adventurewear when considering their outerwear?
There are so many. First, the smooth fiber surface of TENCEL® absorbs moisture more efficiently than cotton. This supports the body’s natural thermal regulating mechanism, keeping your skin pleasantly cool and dry throughout the day and night. The fabric next to your skin feels cool and smooth, and it dries very quickly. It also doesn’t smell. In comparison to polyester and synthetics, there is less available moisture formed on the surface of the fiber for bacteria to grow, so it’s super hygienic.
Aesthetically, it drapes really well so is a great choice for creating more high fashion styles and activewear.
“Combining TENCEL® with wool makes perfect sense as both fibers are natural, and both degrade back into the ground.”
We’d started casually talking to the German Icebreaker team. I then completed some workshops – about the benefits of TENCEL® for adventurewear – with them. I eventually got to meet Jeremy Moon, the founder of Icebreaker, and this led to meetings with Lee Gladish, the company’s Advanced Materials Developer.What excites you the most about working with natural fibers?
Definitely the sustainability factor. Combining TENCEL® with wool makes perfect sense as both fibers are natural, and both degrade back into the ground. TENCEL® compost is very clean and natural; it doesn’t have any negative impact on the earth.
It’s definitely moving faster now as we’re investing so much more in research and development all the time. Sustainability is essential – it’s our key asset – so we’re also re-looking at our other fibers and how we can make changes or improvements.Lastly, what does nature mean to you?
Nature is that which has not been modified by humans. It was here before us and if we’re lucky, we can find it everywhere.
