ABSTRACT:
This invention relates to a manufacturing process of synthetic yarn and the produced yarn which has superior texture and brightness, and excellent color developing, hygroscopicity, and anti-static properties. A plurality of monofilaments is drawn out at an appropriate speed, dried and heated. Then a property enhancing agent containing a metallic salt, alcohol, optional solvent and optional additional functional agent, such as a hygroscopic agent, ultraviolet protecting agent, or resist agent, etc. is applied onto the surface of the filaments which are melted and flame bonded to each other. Multi-filaments are formed with spaces therebetween in which the functional agent remains inserted. The new synthetic yarn is produced after the multi-filaments are subjected to washing, drying and take-up procedures.
