    • A process is described for the production of high strength polyester yarn wherein the conventional spin draw process has been modified. Yarn having a tenacity of at least 7.5 g/d and an elongation of at least 9% may be spun using this process at a speed of at least 1900 meters per minute. The yarn may be used in tire cord and other industrial applications. Figures 1 and 2 illustrate in schematic form the general process steps of spinning and drawing respectively. Polyester in the form of melt extrudable polyethylene terephthalate (PET) is charged to a hopper 12 which empties into a screw extruder 14 which thereupon mixes and heats the polyester to a temperature of about 287°C. The now molten polyester is pressure fed by the extruder to a spinnarette 16 having a plurality of capillaries 17 through which the polyester is extruded. The number of capillaries can vary from about 50 to over 100. The extruded filaments are maintained at a temperature near the melting point of PET by a quench delay collar 20 often referred to simply as a quench collar. The filaments are then quenched by an inert gas or air stream 22 of ambient temperature before passing though a chute 24. The filaments 18 are now in a solid state. At the end of the chute 24 is a tray and kiss roll 26 which applies a conventional spin finish compound to the filaments. The filaments are then converged at point 28 into yarn 30, which is thereafter transported by a pretension godet 32, godets 34 and guide rolls 36 to winder 38, where the yarn is wound and may be either stored for future drawing or may be used as feed immediately to the drawing process in continuous fashion. The drawing process is illustrated in Figure 2. Yarn 30 from winder 38 passes between pretention rolls 42 and over guide roll 44 to top godet 46. The yarn then travels around draw pin 50 which localizes the draw at a point just below top godet 46. The amount of draw is governed by the relative rotational speeds of top godet 46 and a bottom godet 56, the latter rotating at a high speed than top godet 46. After passing over draw pin 50, the yarn 30 passes over a platen 52 before being wound on the bottom godet 56. Rolls 48 and 58 separate the wraps and keep them from rubbing against each other. Platen 52 is heated to a temperature of about 215°C. to about 230°C. From the bottom godet, the now drawn yarn passes through guide loops 60 and is wound onto a spool 62. The yarn is now ready for use at this point.
    • 描述了用于生产高强度聚酯纱线的方法，其中常规旋转拉伸方法已经被修改。 具有至少7.5g / d的韧度和至少9％的伸长率的纱线可以以至少1900米/分钟的速度使用该方法纺丝。 纱线可用于轮胎帘线和其他工业应用中。 图1和图2分别示意性地示出了纺丝和拉伸的一般工艺步骤。 将可熔融挤出的聚对苯二甲酸乙二醇酯（PET）形式的聚酯装入料斗12中，料斗12倒入螺杆挤出机14中，随后将该聚酯混合并加热到约287℃。现在熔融的聚酯由 挤出机到具有多个毛细管17的纺丝纱布16，挤出聚酯。 毛细管的数量可以在约50到100之间变化。挤出的长丝通过淬火延迟轴环20保持在接近PET熔点的温度，通常简称为淬火轴环。 然后在通过斜槽24之前，通过环境温度的惰性气体或空气流22淬灭长丝。细丝18现在处于固态。 在滑槽24的末端是托盘和接触辊26，其将常规的旋涂完成剂施加到长丝上。 然后，细丝在点28处会聚到纱线30中，纱线30此后由预紧导丝管32，导丝辊34和导辊36输送到卷绕器38，纱线被缠绕在其上，纱线可以被储存以供将来拉拔，或者可以用作 以连续的方式立即进行绘图过程。 牵引过程如图2所示。来自络纱机38的纱线30在预制辊42之间经过引导辊44到顶部导丝辊46.然后纱线绕着拉销50行进，拉销50在​​最下导丝托46正下方的位置将拉线定位。 拉伸量由顶部导丝辊46和底部导丝管56的相对旋转速度决定，底部导丝辊56以比顶部导丝辊46高的速度旋转。经过拉丝销50后，纱线30在压板52之前经过， 缠绕在底部导丝辊56上。卷48和58分开包装并防止它们彼此摩擦。 将台板52加热至约215℃至约230℃的温度。从底部的导丝辊中，现在拉伸的纱线通过导向环60并卷绕到卷轴62上。纱线现在准备用于此 点。
