摘要

Continuous process of spinning and stretching of polyamide yarns, comprising the steps of: extruding a polyamide composition with the aid of a spinneret, air cooling the extruded filaments, joining the filaments to form a bundle or compact yarn, heat conditioning treatment, yarn sizing before and/or after conditioning, hot stretching in one or more phases, and winding the yarn on a manufacturing support, the winding step may be preceded, if necessary, by a stage of relaxation; characterized in that the individual filaments are wetted with water or with an aqueous bath of sizing immediately before their joining to form the bundle or yarn.
