Abstract
The invention discloses a spinneret plate special for high-strength polyester industrial yarns. The spinneret plate has the total thickness H1 of 34mm and the excircle diameter D1 of 165mm, and guide holes (1) and corresponding capillary holes (2) are formed in an area with the working diameter D2 of 145mm and the intermediate thickness H2 of 19mm; each guide hole has the diameter D3 of 3mm, the inlet chamfer angle alpha of 90 degrees, and the bottom convergent angle beta of 70 degrees; each capillary hole has the diameter D4 of 0.6mm and the length L of 0.72mm; and the spinneret plate is provided with 192 guide holes (1) and 192 corresponding capillary holes (2) and is made of SUS431 stainless steel. By improving a design on the basis of the conventional spinneret plate for the high-strength polyester industrial yarns, the production stability and product strength of the high-strength polyester industrial yarns are improved, and the yarns have low elongation, and low strength loss in the postprocessing procedure.
Description
Technical field
The present invention relates to a kind of spinning high-strength polyester industrial filament yarn special spinning jet, belong to terylene industrial fibre technology field.
Background technology
Spinnerets is the critical piece in spinning production process, spinning melt being converted into strand, and spinneret plate structure design accounts for extremely important effect in spinning is produced.By the experimental study of spinnerets hole count, guide hole, pore diameter, draw ratio, the reasonable in design of spinnerets, greatly can improve stability and the product quality of spinning production, therefore for a long time, spinning industry is using the main contents of the research and design of spinnerets as explained hereafter.
It is the domestic a kind of new spinning technique just grown up in recent years by Introduced From Abroad advanced production equipment that polyester industrial yarn is produced, owing to lacking experience, technology is immature, also the stage of fumbling is in the selection design of spinnerets, most of manufacturing enterprise still continues to use the theory that civilian silk spinneret design is selected, adopt 0.3-0.5mm small-bore, draw ratio in 2-3 high length-diameter ratio design doubly, this design concept is only to improve for the purpose of production stability.And polyester industrial yarn is mainly used in industrial circle, compared with civilian silk, its Main Feature be embodied in intensity high, extend low.Facts have proved, small-bore, the high-strength terylene industrial of high length-diameter ratio to the low elongation of production high strength are very undesirable.That is, this design cannot production high-performance, high-quality high-strength polyester industrial yarn.
Summary of the invention
The object of the invention is to, a kind of novel high-strength polyester industrial yarns special spinning jet is provided, with overcome prior art exist small-bore, high length-diameter ratio spinnerets cannot the deficiency such as production high-performance, high-quality high-strength polyester industrial yarn.
The present invention is by the following technical solutions: gross thickness H1 is 34mm, and interior thickness H2 is 19mm, and outside diameter D1 is 165mm, is furnished with guide hole and corresponding pore in the region that working diameter D2 is 145mm; Guide hole diameter D3 is 3mm, and entrance chamfering α is 90 °, and bottom convergency β is 70 ° of degree; Pore diameter D4 is 0.6mm, length L is 0.72mm.
The hole count of described spinnerets guide hole and corresponding pore is 192 holes.
SUS431 type stainless steel is adopted to make.
Compared with prior art, because the present invention is to Curve guide impeller on the spinnerets basis of original high-strength polyester industrial yarns, improve the production stability of high-strength polyester industrial yarn and the intensity of product; And extend low, low in the loss of aft-loaded airfoil procedural strength, creative in polyester industrial yarn production industry spinneret design.

Fig. 2 is schematic diagram of the present invention, front view;
Fig. 3 is schematic diagram of the present invention, guide hole and pore enlarged diagram.
Detailed description of the invention
Embodiments of the invention: this spinnerets key technology is creatively to improve following parameter: hole count: 192 holes.
The diameter D3 of guide hole 1 is 3mm, and entrance chamfering is 90 °, bottom convergency 70 °.Pore 2 diameter D4 is 0.6mm, length L is 0.72mm.Above design technology project is mainly to reduce shear stress that spinning process Spray silk pore formed melt stream and the shearing that melt sprays, thus the elastic energy reduced in melt-blowing process stores, improve stability of spinning process, the viscosity reducing melt spinning process is fallen, and is exclusively used in spinning high-strength polyester industrial yarn.
The SUS431 type stainless steel spinnerets of described spinnerets to be outside diameter D1 be 165mm, punch according to the technical scheme of the design in effective perforated area that working diameter D2 is 145mm, punch and comprise guide hole 1 and corresponding pore 2, for spinning high-strength polyester industrial yarn.
Claims (2)
