Method for providing a filtered spinning dope

Abstract

The present invention describes a method of dissolving cellulose, said method comprising: dissolving cellulose in an alkali solution: —filtering the dissolved cellulose, thereby forming a filtered dissolved cellulose solution and a filter reject; —mixing said filter reject having a first viscosity value with a dissolution liquid having a second viscosity value, wherein the second viscosity value is lower than the first viscosity value, to provide a diluted reject stream having a third viscosity value being lower than the first viscosity value of the filter reject; and—separating inhomogeneities from the diluted reject stream.
