    摘要： A spinneret plate for producing a thermoplastic synthetic polymer filament having an exterior configuration with three sides and a generally delta-shaped void extending centrally and axially therethrough, each side of the filament defining a smoothly curved contour extending between a first with a second tip with an inwardly extending depressed region being disposed adjacent to each tip, the void having a geometric center and three major apices, each side of the void being convex in shape and having a first and a second end, each side of the void being formed from two facets that meet to define a minor apex intermediate the first and second end of each side. The spinneret is characterized by a cluster of three Y-shaped orifices centered about a central point. Each Y-shaped orifice has three linear legs joined at a junction point. A connection point of the edges of the two legs located in the straight line connecting to the junction point and the central point corresponds to the minor apex of the void. Each leg has an axis therethrough. One leg of each orifice extends radially outwardly from the junction point with the axis of the outwardly extending leg aligning with a radius extending outwardly from the central point. The axes of each of the other two legs of each orifice project toward a point disposed intermediate adjacent orifices, each intermediate point corresponding to the major apex of the void. Each radially outwardly extending leg is wider than the other legs of the Y-shaped orifice.

    摘要： A bulked continuous filament with a three-sided exterior configuration is characterized in that each side has a smoothly curved contour extending between a first and a second rounded tip with an inwardly extending depressed region being disposed adjacent to each tip. Generally, the filament has an exterior modification ratio in the range from about 1.4 to about 2.5, and a tip ratio in the range from about 2.0 to about 10.0. The filament generally delta-shaped void with three major apices extending centrally and axially therethrough. Each side of the void is convexly shaped and formed from a pair of facets that meet to define minor apices. The void is oriented such that each major apex extends toward the approximate midpoint of one side of the exterior of the filament and each minor apex extends toward a tip of an exterior side. The distance (RM) from the geometric center of the void to each major apex and the distance (Rm) from the geometric center of the void to each minor apex defines an apex ratio (RM/Rm) in the range from about 1.0 to about 1.55. The void occupies from about one percent (1%) to about twenty-five percent (25%) of the cross sectional area of the filament.

    摘要翻译： 具有三面外部结构的膨胀的连续长丝的特征在于，每个侧面具有在第一和第二圆形末端之间延伸的平滑弯曲轮廓，并且与每个尖端相邻设置向内延伸的凹陷区域。 通常，细丝具有在约1.4至约2.5范围内的外部改性比，并且尖端比在约2.0至约10.0的范围内。 长丝通常是三角形的空隙，具有三个主要顶点，其中心地并且轴向延伸穿过其中。 空隙的每个侧面是凸形的，并且由一对面相交以形成较小的顶点形成。 空隙被定向成使得每个主顶点朝向长丝的外部的一侧的大致中点延伸，并且每个次要顶点朝向外侧的尖端延伸。 从空隙的几何中心到每个主顶点的距离（R SUB M N）以及从空隙的几何中心到每个次要顶点的距离（R SUB m N）定义为 在约1.0至约1.55的范围内的顶点比（R M M / R M m）。 空隙占细丝横截面积的约百分之一（1％）至约百分之二十五（25％）。

    摘要： This invention relates to a new cable-twisting process for making yarns suitable for use in carpets. The process involves cable-twisting together two component yarns. At least one of the component yarns comprises two singles yarns co-twisted but not cabled together. The singles yarns may be differentially colored to provide the resulting multi-colored cable-twisted yarn with good color separation and vividness.

    摘要： Disclosed are processes for application of dyes and topical chemistries to single yarns during a yarn rewind process. The process foregoes the need for downstream environmentally unfavorable dyeing and low PH chemical treatment processes on the finished carpet. Further, neutral pH dye solutions can be used instead of the prior art low pH dye solutions. The single, treated yarn can then be twisted, weaved and tufted, twisted yarn under dry conditions, and the twisted yarn subsequently weaved or weaved and tufted, into a finished fabric or carpet. Also disclosed are systems, BCF yarns, and carpets made from the BCF yarn treated by the disclosed processes.

    摘要： Intermittently colored yarns having an intermittent and random dye spacing pattern, and systems and methods of making the same, are disclosed. Such intermittently colored yarns exhibit higher quality and lower manufacturing costs over the known intermittently colored yarns. The intermittent coloring takes place while the yarn is in caterpillar form. Carpets made from such intermittently colored yarns exhibit enhanced aesthetics over carpets made from known intermittently colored yarns. Alternatively, a stain resist, colorless base dye, or bleaching agent can be applied in the same intermittent and random spacing pattern to the intermittently colored yarns prior to subsequent dyeing. This creates a mirror image like color effect to the resulting yarn.
