Abstract

1. Improved process for the stretching of synthetic filaments, especially filaments on a base of polypropylene or the like, composed of two steps, each of which corresponds to a partial stretching, the first step taking place under wet conditions by means of a filament feed mill (1) and a stretching mill (2), a liquid bath (3) and submerged guide rolls (4) being provided between these two elements (1, 2), the second stretching step using the stretching mill (2) of the first step, which now functions as a feed mill for the filaments laden with liquid as a result of their passage through the said bath (3), the said filaments being conveyed towards heated means of the second stretching step (6), characterized in that the said heated means are brought to a temperature higher than the fusion temperature of the filaments in the dry state.
