Abstract
PURPOSE: After treated with a finishing oil of aqueous emulsion and passed through a fluid nozzle, an extruded polyamide yarn is exposed to air under extension and heating and immediately drawn, thus producing stably a polyamide yarn of high tenacity and low shrinkage using an oil of aqueous emulsion.
CONSTITUTION: An extruded polyamide yarn is treated with a finishing oil of aqueous emulsion and passed through a fluid nozzle so that the oil is redistributed to each filament. Then, the yarn is exposed to air under extension of 1W10% to convert the emulsion film from oil-in-water into water-in-oil phase, heated to lower the water content and directly, without being wound up, drawn. The above direct spin-draw produces high-tenacity polyamide yarns of low shrinkage in high drawing yield.
