Federal Way, Washington, USA, 18 July 2008 — Lenzing, the world market leader in cellulose staple fibers, and Weyerhaeuser, one of the world's largest forest products companies, will work together on the development of novel lyocell-based nonwoven fabrics. A memorandum of understanding was signed on 15 July 2008.
The objective of the collaboration is to develop a technology for the large-scale industrial production of an innovative and sustainable cellulose-based material for industrial and personal care applications. The technology will provide an alternative to petroleum-based materials in nonwoven products with raw materials based on renewable wood fiber.
The product to be developed is based on lyocell technology in which a solution of cellulose is processed directly and without intermediate process steps into a nonwoven fabric.
Lenzing, the leader in lyocell technology, is the only commercial global supplier of lyocell fibers. The company brings more than 20 years of expertise in the development of this environmentally sustainable technology to create cellulose products from the renewable raw material wood. The company has a strong intellectual property portfolio in lyocell technology and the brand name TENCEL®.
Weyerhaeuser is a global forest products company that grows and harvests trees, builds homes, and applies technology to cellulose to create innovative, sustainable products essential to everyday living. The company has an extensive intellectual property portfolio in forestry, wood products, and cellulose fibers. Its focus on technology and innovation has resulted in the introduction of a number of new cellulose-based products, such as Peach® pulp. Weyerhaeuser has invented and patented unique technology to form nonwoven materials. This technology is based on the extrusion of a cellulose solution through a multihole nozzle to directly form lyocell nonwoven material.
The new collaboration combines the expertise of these two innovative companies. Both companies are dedicated to expanding the range of applications for renewable resources and both are committed to the principles of sustainability.
