Problems solved by technology

[0003] During the processing of polyester filaments, polyester filaments need to be stretched. Before stretching, polyester filaments need to be thermally softened. Since the spinning is stretched under uneven heating, the stretching effect of polyester filaments will be poor. There are hairs, broken ends, and uneven thickness

Embodiment Construction

[0040] The following is attached Figure 1-3 The application is described in further detail.

[0041] The embodiment of the present application discloses a polyester filament preparation process. The process includes the following steps: step S1, melting, first select polyester slices, feed the polyester slices into a screw extruder and melt and extrude them into spinning stock solution; step S2, spinning, send the spinning stock solution into the spinning machine and It is sprayed out from the spinneret to form a mother filament with a thicker diameter; step S3, cooling and oiling, blowing the sprayed mother filament to cool it, and then oiling the mother filament, when oiling, immerse the mother filament in polyester oil agent, the mother silk is oiled through the polyester oil agent; first, the oiled mother silk is sent to the network device and pre-networked; step S4, stretching and setting, firstly, the mother silk is preheated, and the preheating temperature is 105 -11...

Abstract

The invention relates to a polyester filament preparation technology and equipment. The technology comprises the following steps: S1, performing melting: selecting polyester slices, and melting the polyester slices into a spinning solution; S2, performing spinning: feeding the spinning solution into a spinning machine, and spraying out the spinning solution through a spinneret plate to form motheryarns; S3, performing cooling and oiling: cooling the sprayed mother yarns through air blowing, and then performing oiling treatment on the mother yarns; S4, performing stretching and shaping: feeding the mother yarns into a stretching device for stretching and shaping to form slender filaments; S5, performing network processing, wherein the stretched and shaped filaments are fed into a network device for network processing; and S6, performing winding: specifically, winding the interlaced yarns to obtain a finished product. The technology and the equipment disclosed by the application have the effects of improving the yarn stretching effect and reducing the phenomena of fuzzing and yarn breaking in the stretching process.

Description

technical field [0001] The present application relates to the field of polyester filament processing technology, in particular to a polyester filament preparation process and its equipment. Background technique [0002] Polyester filament is made of polyester. Polyester is an important variety in synthetic yarn. It is the trade name of polyester yarn in my country. It is based on purified terephthalic acid (PTA) or dimethyl terephthalate ( DMT) and ethylene glycol (MEG) as raw materials, the fiber-forming high polymer prepared by esterification or transesterification and polycondensation reaction - polyethylene terephthalate (PET), after spinning and post-spinning Process the finished silk thread. [0003] During the processing of polyester filaments, polyester filaments need to be stretched. Before stretching, polyester filaments need to be thermally softened. Since the spinning is stretched under uneven heating, the stretching effect of polyester filaments will be poor. Th...
