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 the high strong type polyester industrial filament yarn of a kind of spinning special spinning jet, belong to terylene industrial fibre technology field.
Background technology
Spinnerets is the critical piece that in the spinning production process spinning melt is converted into strand, and the spinnerets structural design is accounting for important role in spinning is produced.Experimental study by spinnerets hole count, guide hole, pore diameter, draw ratio, the reasonable in design of spinnerets, can improve stability and product quality that spinning is produced greatly, therefore for a long time, the spinning industry is with the research and design of the spinnerets main contents as explained hereafter.
Polyester industrial yarn production is domestic by introducing a kind of new spinning technique that external advanced production equipment has just grown up in recent years, owing to lack experience, technology is immature, selection design at spinnerets also is in the stage of fumbling, most of manufacturing enterprises still continue 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 a purpose to improve production stability only.And polyester industrial yarn is mainly used in industrial circle, compares with civilian silk, and its Main Feature is embodied in the intensity height, elongation is low.Facts have proved that the high strong type terylene industrial that small-bore, high length-diameter ratio hang down elongation to production high strength is very undesirable.That is to say that this design can't the production high-performance, high-quality high strong type polyester industrial yarn.
Summary of the invention
The objective of the invention is to, a kind of novel high-strength polyester industrial yarns special spinning jet is provided, with the spinnerets that overcomes small-bore that prior art exists, high length-diameter ratio can't the production high-performance, deficiency such as high-quality high strong type polyester industrial yarn.
The present invention is by the following technical solutions: gross thickness H1 is 34mm, and outside diameter D1 is 165mm, is that 145mm, interior thickness H2 are furnished with guide hole and corresponding pore in the zone of 19mm at working diameter D2; Guide hole diameter D3 is 3mm, and inlet chamfering α is 90 °, and bottom convergency β is 70 ° of degree; Pore diameter D4 is that 0.6mm, length L are 0.72mm.
The hole count of the pore of described spinnerets guide hole and correspondence is 192 holes.
Adopt SUS431 type stainless steel to make.
Compared with prior art, because the present invention has improved the intensity of the production stability and the product of high strong type polyester industrial yarn to improving design on the spinnerets basis of original high-strength polyester industrial yarns; And extend low, low in back process loss of strength, creative on 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.
The specific embodiment
Embodiments of the invention: this spinnerets key technology is creatively to have improved following parameter: hole count: 192 holes.
The diameter D3 of guide hole 1 is 3mm, and the inlet chamfering is 90 °, 70 ° of bottom convergencys.Pore 2 diameter D4 are that 0.6mm, length L are 0.72mm.Above design technology project mainly is to reduce spray silk process Spray silk pore to the shear stress of melt thread formation and the shearing of melt ejection, thereby the elastic energy that reduces in the melt-blowing process stores, improve stability of spinning process, reduce the viscosity of melt spinning process and fall, be exclusively used in the high strong type polyester industrial yarn of spinning.
Described spinnerets is that outside diameter D1 is the SUS431 type stainless steel spinnerets of 165mm, in working diameter D2 is effective perforated area of 145mm according to the design's technical scheme punching, punch and comprise and guide hole 1 and corresponding pore 2 are used to spin high strong type polyester industrial yarn.
Claims (3)
1. one kind high strong type polyester industrial yarn special spinning jet, it is characterized in that: gross thickness H1 is 34mm, outside diameter D1 is 165mm, is that 145mm, interior thickness H2 are furnished with guide hole (1) and corresponding pore (2) in the zone of 19mm at working diameter D2; Guide hole (1) diameter D3 is 3mm, and inlet chamfering α is 90 °, and bottom convergency β is 70 ° of degree; Pore diameter D4 is that 0.6mm, length L are 0.72mm.
2. high strong type polyester industrial yarn special spinning jet according to claim 1 is characterized in that: the hole count of the pore (2) of described spinnerets guide hole (1) and correspondence is 192 holes.
