Abstract
False twist texturing uses the thermoplastic property of synthetic yarn and produces a bulk and a stretch by giving the filament a permanent crimp. This study investigated the effects of false twist texturing parameters, disk/yarn(D/Y) and heater temperature, on the physical properties of nylon textured yarn. D/Y was a primary determinant of twist numbers of filaments and was proportionally increased with the twist numbers of filaments, resulting in an increase of crimp rigidity of the textured yarn. Heater temperature, a determinant of the heat setting of transformed filaments, was proportionally increased with the increase of crimp rigidity. Nylon 6 was partially melted at $190^{\circ}C$. This study consequently suggested the optimal parameters of nylon 6 85d/68f full-dull POY.
