聚对苯二甲酸乙二醇酯着色方法和用于制造膨化变形地毯长丝的系统
摘要：
用于从PET制造具有色调着色的膨化变形长丝的方法和系统包括：挤出机(202)；静态混合组件(208)，联接到挤出机并包括壳体和设置在壳体内的一个或多个单独的静态混合元件；该方法和系统还包括多个着色剂端口和一个或多个纺纱机(212)，该多个着色剂端口沿着静态混合组件的长度，使得多个着色剂端口中的每个被配置为在沿着静态混合组件的长度的不同位置处向聚合物流提供着色剂(204)，该一个或多个纺纱机定位在静态混合组件的下游并联接到静态混合组件以接收着色的聚合物流。纺纱机可以被配置为将着色的聚合物流形成为具有色调颜色效果的膨化变形地毯长丝。
摘要（英）：

Systems for manufacturing bulked continuous filament having tonal coloring from PET comprise, in various embodiments: (1) an extruder; (2) a static mixing assembly coupled to the extruder comprising: (a) a housing, and (b) one or more individual static mixing elements disposed within the housing; (3) a plurality of colorant ports along a length of the static mixing assembly such that each of the plurality of colorant ports is configured to provide colorant to a polymer stream at a different location along the length of the static mixing assembly; and (4) one or more spinning machines positioned downstream of the static mixing assembly and coupled to the static mixing assembly to receive the colored polymer stream. The spinning machine(s) may be configured to form the colored polymer stream into bulked continuous carpet filament having a tonal color effect.
