Abstract
The invention discloses a process for refining yarn or sliver having a length of at least 1 meter, including the step of feeding the yarn or sliver and a liquid into a refiner, which includes refiner fillings having a body surrounding a central hole (), and at least one inlet () for the yarn or sliver, and the thus obtained pulp-like materials and its use for making friction materials, paper, and gaskets. In particular, the refiner has a refiner filling (), wherein the yarn or sliver is fed through an inlet positioned in the refiner filling. The present invention further relates to the refiner filling including at least one, preferably eccentric, inlet for yarn or sliver. The inlet comprises an inlet hole which includes an inclined slope () on the outflow side of the inlet, the inclined slope serving to guide the yarn or sliver from the inlet hole to the surface of the refiner filling. The invention further relates to a refiner including such refiner filling.
