Abstract (en)
[origin: WO2015004074A1] The invention relates to spunbonded nonwovens and yarns made of fiber-forming polymers that can be produced from a spinning material that contains fiber-forming polymers, wherein the spinning material is spun from at least one spinning hole and the spun thread is drawn by gas streams that are continuously accelerated to a high speed by means of a de Laval nozzle, characterized in that the spinning material contains lignin as an additive.
