Abstract

The invention relates to a processing process of lustrous trilobal profiled polyester pre-oriented color yarn. The pre-oriented color yarn processing process comprises the following steps of: drying large lustrous PET (polyester) chips in a drying machine; adding the dried large lustrous PET chips and coloring masterbatch into a screw extruder for heating and melting; filtering heated and molten melt through a CPF (catalyzed particulate filtering) double-cylinder melt filter; adding the filtered melt into a spinning manifold for distributing and preserving heat; metering the heated and molten melt through a metering pump of the spinning manifold, and pressing the melt into a spinneret plate, wherein the ejection hole of the spinneret plate is in the shape of Y; ejecting the melt through the spinneret plate to form melt thin flows, and performing air cooling by means of an air cooling device; and oiling after cooling; and winding the oiled yarns through a winding head. According to the pre-oriented color yarn processing process, the product quality is improved by optimizing the process, and the products have stable tension, high profile degree and high color fastness in the post-processing process.
