Literature review:
In order to protect our customers Lenzing has developed technology that enables it to differentiate Lenzing Modal from all other fibers in yarn, fabric or garment form, including other fibers claiming to be Modal.
Modal – makes the world a softer place
Softness to perfection
Perfect for fabrics next to the skin
In homewear for softness & absorbency
World’s No 1 branded modal fibre
The perfect blend partner
Natural partner for cotton
Unique cross-section adds permanent softness
Enhances touch even after repeated washing
Natural wood
Made from beech wood – natural raw material
Consistent and reliable quality
3.1 Beechwood fiber
Out of the wood
Lenzing Modal®, a modal fiber from Lenzing, is extracted from beechwood. The beech tree is quite unique and has grown in Europe for a very long time. Directly from beechwood forests, Lenzing Modal® gives each and every textile a natural image.
3.2 Edelweiss technology
Fiber from Austria
Lenzing Modal®, a modal fiber from Lenzing, is like the Edelweiss flower: made in Austria, pure and natural. Full integration at the Lenzing site in Austria makes it possible to produce the fiber in an environmentally sound way due to the generation of excess energy and the recovery of component parts of the wood. Even pulp producti on at Lenzing is self-sufficient in terms of energy and is an important supplier of energy for the entire operation.
A solvent, an amine oxide, is used to dissolve the cellulose directly into a very viscous solution. After filtration, the solution is extruded to yield fine filaments, from which the

solvent is subsequently removed by washing and then recycled. The resulting tow is then cut to produce staple fiber. Modal is third generation viscose fiber. This third generation viscose fiber is made from Eucalyptus raw material which is also used in viscose manufacturing. Modal is made from special process only which makes it very strong in both dry & wet conditions.
Modal is a regenerated cellulose fibre made from dissolving pulp ( bleached wood pulp).it was first manufactured in 2010 it is manufactured by Lenzing AG of Lenzing, Austria, under the brand name “ Modal by Lenzing”, and under the brand name Lenzing Modal by the Tencel Group, now owned by Lenzing AG.
According to Faderal Trade Commision Definition for Modal fibre: A cellulose fibre obtained by an organic solvent spinning process where:
“Organic solvent” means a mixture of organic chemicals and water, and
“ Solvent spinning” means dissolving and spinning without the formation of a derivative.
Although it is givien a separate generic name, the FTC classifies ”Lyocell as a sub-category under Rayon”. Lenzing fibers are man-made cellulose fibers. They are made from the natural raw material wood which contains about forty percent cellulose. The natural origin contributes to the fibers‘ excellent properties such as absorbency and moisture management, the industrial production process provides purity and clearly defined, uniform quality. Lenzing Group is the only company worldwide combining the manufacturing of all three man-made cellulose fiber generations on a large industrial scale under one roof – from the classic viscose to modal and lyocell fibers.
3.3 Product Types and Applications
Uses of Lenzing Modal® in textiles
Homeware
Fashion knitwear
Underwear and socks
Terry products
3.4 The softest Lenzing fiber is naturally soft on the skin and exceptionally ecological.
As a result of using Edelweiss technology, Lenzing Modal is CO2 neutral. Edelweiss stands for a “symbiotic” production process – pulp, the raw material, is produced at the same site as the Modal fiber itself. Thus production can be done while going easy on energy and other resources. Simply Edelweiss!
Lenzing Modal is a cellulose fiber speciality distinguished by its particular softness. It is preferably used for high quality clothing. The fiber has enhanced user properties (strength, dimensional stability and others).
