Abstract

The invention relates to a spinning method, and in particular relates to a system for producing POY-FDY (Pre-Oriented Yarn-Full Drawn Yarn) compound polyester yarns from a melt direct-spinning stock solution and a preparation method thereof. The system is used for spinning POY and FDY. A PET (Poly Ethylene Terephthalate) melt tower is communicated with a melt cooler, a color paste stock bin and the melt cooler are communicated with a multi-factor coupler, the multi-factor coupler is communicated with a dynamic mixer, the dynamic mixer is communicated with a spinning manifold, and the spinning manifold is communicated with a POY device and an FDY device. The preparation method comprises the steps of PET melt delivery, color paste delivery, split-flow treatment in the spinning manifold, POY spinning and FDY spinning. The system for producing the POY-FDY compound polyester yarns from the melt direct-spinning stock solution and the preparation method thereof have the advantages of compact structure, shorter production process flow, simpler and more convenient operation, higher production efficiency, lower energy consumption and loss, more stable quality, reduction of pollutant emission, and ecological environmental protection.

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 i...
