Abstract

A method and apparatus is provided for producing a synthetic multifilament yarn having appearance, bulk and hand characteristics of conventional spun yarns of staple fibers while retaining strength characteristics of continuous filament yarns. The multifilament yarn is air jet textured to form loops, bows, coils and the like in at least the surface filaments thereof and at least some of these loops, bows, coils and the like only in the surface filaments are parted while the interior or core filaments remain substantially intact to form a yarn having free filament or fiber ends projecting from a substantially continuous filament core. The interior or core filaments are shielded or protected from being parted by false twisting the yarn (without heat setting the twist therein) to provide a substantially closed form with the interior or core filaments surrounded by the surface filaments and by parting the surface filaments while the yarn has twist therein. Also, other steps are taken and means are provided for limiting the filament parting action solely to the surface filaments. Finally, the yarn is heat set after the filaments are parted and after the twist is removed to fix the characteristics imparted in the previous processing steps therein.
