Manufacture of bamboo textiles
These fibers often have a beautiful shine with less curls and they are easier to clean than, for example, cotton. It all started with the development of viscose back in the late 1800s and most recently the Lyocell manufacturing method was introduced in the early 1990s for the purpose of finding a more environmentally friendly manufacturing method.
"We focus on more environmentally friendly production"
In general, the plant material is first cut into smaller pieces (wood chips). Then they are dissolved into a porridge and the cellulose is extracted.
The syrup-like substance is called schmelze. Next, it is pressed through a spinneret, a funnel with small holes.
The threads that come out are drawn to the desired thinness, after which the fibers are cooled, washed, dried and finally wound up on keys as infinitely long filament yarn. "Lyocell was created in the early 1990s"
PREPARATION OF LYOCELL
The Lyocell method is very similar to the process described above with the one, very important, difference that the Lyocell method takes place in a closed circuit and that you recycle the chemicals that are used in the decomposition process.
It has not yet been possible to find an environmentally friendly alternative to these chemicals used in the decomposition process. Therefore a system has been created that recycles about 99% of the chemicals. In addition, this method requires significantly less water consumption than the classic viscose production.
Just so you know, Lyocell is the same as Tencel, but the name Tencel may only be used when it comes from the Austrian factory Lenzing - pioneers in environmentally friendly production methods.
