    Abstract: A process for producing a partially ester-exchanged SIPM such as an alkali metal bis(2-hydroxyethyl) 5-sulfoisophthalate produced from an alkali metal dimethyl 5-sulfoisophthalate in an alcohol is disclosed. The partially ester-exchanged SIPM in an alcohol can be used to copolymerize with oligomer of terephthalic acid or dimethyl terephthalate and an alcohol. Also disclosed is a process for controlling the color of a dyeable polyester using a phosphorous compound.

    Abstract: 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 2.0, and a tip ratio in the range from about 2.0 to about 4.0. 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 (R M ) from the geometric center of the void to each major apex and the distance (R m ) from the geometric center of the void to each minor apex defines an apex ratio (R M /R m ) in the range from about 1.0 to about 1.55. The void occupies from about four percent (4%) to about twenty-five percent (25%) of the cross sectional area of the filament.

    Abstract translation: 具有三面外部结构的膨胀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，并且向内延伸的凹陷区域邻近于每个尖端设置。 通常，细丝具有约1.4至约2.0范围内的外部改性比，并且尖端比在约2.0至约4.0的范围内。 长丝通常为三角形空隙，三个主要顶点中心延伸并且轴向延伸穿过其中。 空隙的每个侧面都是凸出的形状，并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（RM）和从空隙的几何中心到每个次要顶点的距离（Rm）定义在约1.0至约的范围内的顶点比率（RM / Rm） 1.55。 空隙占细丝横截面面积的约4％（4％）至约25％（25％）。

    Abstract: 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 corresponding to a major 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 a minor apex of the void. Each radially outwardly extending leg is wider than the other legs of the Y-shaped orifice.
