ABSTRACT:
An apparatus and a method is disclosed for the production of synthetic filament yarns containing substantial portions of additives which retain or develop a stickiness under certain yarn spinning conditions. Such additives cause the individual filaments in the yarn to adhere to each other under hot, humid spinning conditions such as are countered more particularly in nylon spinning-steam conditioning. The apparatus disclosed is a convergence guide which brings the filaments together in the spinning column just prior to the steam conditioner, but in so converging the filaments, maintains the individual filaments in a spaced relationship to each other such that they remain separate from each other as they pass through a steam conditioner.
