These spinning machines are relatively expensive, however, and much research has been done to obtain an artificial fiber suitable for spinning on ordinary three-roll spinning machines used in cotton spinning. However, it has been found that roving fibers of the corresponding length of about 20 to 40 millimeters could not be processed because of their weaving and their brittleness, for example by the simple spinning processes used.

It has been found that several conditions must be fulfilled simultaneously to obtain a fiber which
