Beech wood is being barked, cut up and cooked with sulfide under pressure until the so-called cellulose develops. After a cleaning process this cellulose is chemically treated with a 18% caustic soda. This syrup-like viscose is stirred and cooled and pressed through shower-like nozzles with a speed of 50-150 meters, and in a so-called drop bath then the firm filament hardens.
Now the fiber in its wet condition is mechanically stretched to reach its final thickness and then rolled up on a coil (continuous filament). All used chemicals are washed carefully from the fiber and brought back to the production cycle.
In contrast to viscose the Lenzing Modal® fiber shows firmness in wet and dry conditions, furthermore it is extraordinarily resistant against stretching. Lenzing succeeded to obtain and even exceed the firmness level of cotton by the use of regenerated cellulose material. Therefore the Lenzing Modal® fiber is the perfect partner for Chillaz.
