The wool was originally found in wool, which did not originate directly from the animal, but it was obtained from wool containing lumps. Artificial wool was thus not synthetic wool but came from reuse.
The artificial turf production process was developed in the early 19th century. Artwolf factories existed until the beginning of the 2nd half of the 20th century. Process
The lumps were stripped of dust and dirt in a knuckle mill. Then they were subjected to a wet carbonization process or a dry carbonization process. The purpose of this was to destroy the vegetable fibers. The lumps were treated with an acid (sulfuric acid or hydrochloric acid gas) and then subjected to a temperature of 110 ° C or higher. By knocking, the charred vegetable fibers (cotton, linen) were then removed.
Then the lumps were washed and greased, after which they were dismantled by the lump tear machine (also called artificial wool mill) until a waxy mass was formed. This was delivered to the waste spindles where the resulting shorter wool fibers were often mixed with longer fibers. By greasing the lumps, they became smooth and less short fibers were produced. Industry
In the Netherlands there are dozens of artificial wolf mills and artificial wool mills. The first dates from the 1940s, and until the 1950s, some of these factories were still active.
