Embodiment Construction

[0014] The present invention will be further described in detail below in combination with specific embodiments.

[0015] The processing technology of glossy trilobal special-shaped polyester pre-oriented dyed yarn comprises the following steps:

[0016] Dry the Dayouguang PET slices in a dryer at a drying temperature of 160°C~165°C. After drying, the moisture content of the Dayouguang PET slices is controlled at 15~25ppm to prevent agglomeration. The general drying time is 8~12 hours for comparison Suitable.

[0017] After drying, the bright PET chips and colored masterbatch are added to the screw extruder for heating and melting. The temperature of each zone in the screw extruder is set at 285°C~292°C. Body filter filtration, filtration accuracy of 15μm;

[0018] Add the filtered melt into the spinning box for distribution and heat preservation. The temperature of the melt distribution pipe in the spinning box is 285 ° C ~ 290 ° C to reduce wool and broken ends; the heated...

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.

Description

technical field [0001] The invention relates to a process for processing glossy trilobal special-shaped polyester pre-oriented dyed yarn. Background technique [0002] In recent years, due to the rapid growth of polyester filament production capacity, most of them are conventional products. Compared with conventional silk, the glossy trefoil special-shaped section has a brighter surface, and its fabric is not easy to pilling, has a good hand feeling, and its performance is similar to natural silk, which can replace real silk and rayon fabrics. At the same time, colored yarn is very popular because it does not need dyeing treatment and does not pollute the environment in the subsequent processing process, so its market is optimistic. The product quality of the existing processing technology is on the low side. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the existing pre-oriented dyed yarn processing technology for glossy sp...
