Abstract: An improved process for the production of springy, textured thermoplastic yarns wherein the yarns are compacted and compressed in an enclosed space by means of a flow of compressed fluid heated at a temperature that allows for the fixing of the yarn, a portion of the fluid affecting the movement of the yarn and another portion escaping to the side from the enclosed space, such process being characterized in that the escape of fluid is effected at a pressure which is lower than the feed pressure, but higher than atmospheric pressure. The apparatus for effecting such process comprises a suction nozzle constituting a passage for the yarn and a delivery tube for admission of pressurized fluid, a tubular chamber communicating with the nozzle, and having orifices therein, a housing defining a closed space enclosing at least a portion of the length of the tubular chamber and having a pressure regulation system associated therewith, and means for controlling the discharge of the treated yarn.
Abstract translation: 一种用于生产弹性织构的热塑性纱线的改进方法，其中纱线通过在允许纱线固定的温度下加热的压缩流体流在封闭空间中压实和压缩，一部分流体影响 纱线的移动和另一部分从封闭空间逸出到侧面，其特征在于流体的逸出是在低于进料压力但高于大气压力的压力下进行的。

Abstract: Yarns showing novel color effects varying along their length are made by feeding a thermoplastic yarn into a confined space, so forming a long stack of uniform cross section of folded yarn in the said space, by means of a jet of fluid at a temperature sufficient to set the resulting crimp in the yarn, and feeding a dye solution, preferably two or more dye solutions at different locations to the same cross section of the stack, under conditions such that the resulting intensity of color of the yarn due to each dye falls off across the stack from the point or points of application.
Abstract translation: 显示出沿其长度变化的新颜色效果的纱线是通过将热塑性纱线喂入密闭空间而形成的，从而在足够的温度下通过流体喷射形成在所述空间中的折叠纱线的均匀横截面的长堆叠 将所得到的卷曲设定在纱线中，并且在使得由于每种染料导致的纱线的颜色强度下降的条件下，在不同位置处将染料溶液，优选两个或更多个染料溶液馈送到叠层的相同横截面 跨越堆栈的点或应用点。

Abstract: A NOVEL SYNTHETIC FILAMENT AND ARTICLES PRODUCED THEREFROM WHEREIN SAID FILAMENT HAS A TETRALOBAL CONFIGURATION, THE FILAMENT AND ARTICLE PRODUCED THEREFROM POSSESSING IMPROVED CHARACTERISTICS OF RIGIDITY AND GOOD COVERING POWER. SUCH FILAMENTS ARE CHARACTERIZED IN THAT THE RATIO OF THE RADIUS OF THE INSCRIBED CIRCLE, I.E., THE CIRCLE WHICH PASSES THROUGH THE CONNECTING POINT OF THE LOBES, TO THE RADIUS OF THE CIRCUMSCRIBED CIRCLE, I.E., THE CIRCLE WHICH PASSES BY THE SPEX OF THE LOBES, IS WITHIN THE RANGE OF 0.25 AND 0.42. THE TETRALOBAL CONFIGURTION IS FURTHER CHARACTERIZED IN THAT TWO ADJACENT ANGLES FORMED BY THE AXES OF THE LOBES ARE BETWEEN GREATER THAN 90* TO 120*. THE TETRALOBAL SYNTHETIC FILAMENTS ARE PREPARED BY EXTRUDING A THERMOPLASTIC POLYMER IN A MOLTEN CONDITION THROUGH A SPINNERET, THE APERTURES OF WHICH ARE COMPOSED OF FOUR SLITS OF SUBSTANTIALLY EQUAL LENGTH FORMING A CROSS OF TWO ADJACENT ANGLES OF BETWEEN GREATER THAN 90* TO 120*, THE FILAMENTS BEING THEREAFTER PASSED THROUGH A GASEOUS ATMOPHERE AND THROUGH A COOLING BATH MAINTAINED AT A TEMPERATURE LOWER THAN 100*C.
