Abstract
The properties of textured POY PES multifilament yarns are conditioned by texturing temperature, texturing speed,
stretching degree and by the ratio of disc peripheral speed and yarn speed. In the paper attention is focused on crimping
of yarns. New method for defining crimping limits is proposed. The method is based on the flow analysis of the
force-elongation function. POY multifilament polyester yarns, having the fineness of 167f36x1 dtex were analyzed. The
texturing of PES multifilament yarns was performed using different first heater temperatures (350 oC, 400 oC, 450 oC)
and maintaining the constant temperature of the second heater (180 oC), then with different texturing speeds
(500 m/min, 600 m/min, 700 m/min, 900 m/min, 1000 m/min, 1100 m/min), using different ratio of the disc circumferential
speed to yarn speed (2.15, 2.20, 2.25) and at the extension degree of 1.665.
