Problems solved by technology

The latest also has the production process of POY and FDY one-step colored fiber plying, but these existing technologies improve the production, that is, the one-step method is mainly the winding stage, and the pre-spinning step uses POY and FDY respectively. Production of different polyester yarns, and then ply winding, did not realize the real co-spinning and winding one-step method, did not realize the online additive production technology of melt direct spinning, and did not realize the process integration of colored skin-core structure composite polyester yarns

Abstract

The invention relates to a spinning method, in particular to a system for producing POY and FDY composite polyester yarns from melt direct spinning stock solution and a preparation method thereof, which is used for spinning POY and FDY. The PET melt tower is connected with the melt cooler, the color paste silo and the melt cooler are respectively connected with the multi-element coupler, the multi-element coupler is connected with the dynamic mixer, the dynamic mixer is connected with the spinning box, and the spinning The silk box is connected with the POY device and the FDY device respectively. Carry out the following steps: PET melt conveying → color paste conveying → entering into the spinning box for diversion treatment → POY spinning → FDY spinning. The system and its preparation method for producing POY and FDY composite polyester yarns from melt direct spinning dope have compact structure, shorter production process, easier operation, higher production efficiency, lower energy consumption loss, more stable quality, and reduced pollutant discharge. Eco-friendly.

Description

technical field [0001] The invention relates to a spinning method, in particular to a system for producing POY and FDY composite polyester yarns from melt direct spinning stock solution and a preparation method thereof, which is used for spinning POY and FDY. Background technique [0002] The technology of white mixed fiber composite polyester yarn is relatively mature, but it is mostly produced by two-step process, which has long process flow, low production efficiency, large energy consumption and loss, and to make colored fabrics, it is necessary to dye the fabric after weaving. Subsequent deep processing links are seriously polluted and not environmentally friendly. [0003] For example, the equipment and method for one-step production of chemical fiber polyester composite yarn disclosed in the patent application document CN102618983A, the one-step 24 head / position multi-different mixed fiber composite fiber spinning and winding joint production device disclosed in the p...
