Embodiment Construction

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0019] Such as figure 1 with figure 2 As shown, a production device for producing fine denier POY by sub-end spinning includes a spinneret 1 with a spinneret distribution disc 2, wherein the spinneret distribution disc 2 is divided into a first part on the left and a second part on the right. Two parts, the first and second parts are isolated from each other, the spinneret 1 includes four circles of radially distributed spinneret holes 3, and each spinneret hole 3 in each circle of spinneret holes is communicated through a shallow groove 4; the spinneret holes 3 includes a guide hole groove 5 and a microhole 6. The gui...

Abstract

The invention discloses a device for producing fine denier POY (polyester pre-orientated yarn) by a head spinning method, which comprises a spinneret plate with a spinneret plate distribution plate, wherein the spinneret plate distribution plate comprises a first part positioned at the left side and a second part positioned at the right side, and the first part and the second part are separated from each other; the spinneret plate comprises four rings of radially distributed spinneret holes, and the spinneret holes in each ring of spinneret holes are communicated by shallow grooves; each spinneret hole comprises a pilot hole groove and a microhole, and the pilot hole groove comprises a cavity, a first-stage cone and a second-stage cone which are sequentially arranged, so that two-stage cone angle transition is formed; and the microhole is arranged at the lower end of the second-stage cone. Therefore, the defect of size unevenness of products can be overcome, and the size unevenness linear density deviation value of the products can be reduced.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a production device for producing fine denier POY (Polyester Pre-Oriented Yarn) by sub-end spinning. Background technique [0002] In the field of spinning technology, sub-end spinning is a split-fiber technology. Polyester melt is extruded through components to form filaments. In conventional spinning, each component corresponds to a bundle of filaments. Sub-end spinning is a component that is divided into two bundles. Silk, the spinning method is characterized by large output and low energy consumption. The production device of sub-end spinning to produce fine denier POY is an important equipment, which usually consists of hopper, screw extruder, metering pump, spinning box, blowing device, side blowing window, oil nozzle and winding, etc. The process The process mainly includes: melt, metering, spinning, side blow molding, oiling and winding, etc. [0003] However, during t...
