Abstract
A process for pre-drying textile filaments after wet treatment and a device for practicing this process. The process consists essentially in applying simultaneously to a layer of wet filaments (3) passing by on a conveyor (4) with a permeable conveying surface, on the one hand, a mechanical squeeze-drying action and, on the other hand, a pressure difference by circulation of air through said layer (3).
