Description
Technical field
The present invention relates to special-shaped superhigh molecular weight polyethylene fibers field, more particularly to one kind to be used for special-shaped super high molecular weight
The spinneret of polyethylene fibre production.
Background technology
Superhigh molecular weight polyethylene fibers are also known as high strength and modulus polyethylene fibre, are 10 by molecular weight6More than
Polyethylene powders are formed by wet spinning extraction stretching again after being swelled with technical white oil through spinneret spinneret, and spinneret is super
An important part in high molecular weight polyethylene fiber spinning, it is included into charge level and discharge feed side, enters charge level and is provided with
Charging hole, discharge feed side are provided with discharge opening, and the high molecular polymer of viscous state is transformed into the thin of particular cross section shape by spinneret
Stream, then can be changed into specific fiber through supercooling stretching.
The architectural feature of common superhigh molecular weight polyethylene fibers spinneret is circle in production, due to super high molecular weight
Polyethylene viscous state has higher viscosity, is difficult that the ultra-high molecular weight polyethylene of viscous state and white oil are swelled into thing in production
Fiber of the section for abnormity is converted into by spinneret.
The content of the invention
In order to solve the above problems, it is used for special-shaped superhigh molecular weight polyethylene fibers it is an object of the invention to provide one kind and gives birth to
The spinneret of production, the present invention have higher draw ratio, and its special template, charging aperture and discharge hole structure can make spun different
Shape superhigh molecular weight polyethylene fibers moisture absorbing and sweat releasing, washable rapid-curing cutback.
The present invention provides a kind of spinneret for the production of special-shaped superhigh molecular weight polyethylene fibers, including spinneret sheet
Body, the section of the spinnerette body is rounded rectangular-shaped, and it is provided with some spinneret orifices, and the spinneret orifice includes charging and imported
Section, in lead to section and thin footpath introduction segment and thin diameter section.
The both ends of the spinnerette body are respectively to feed end face and discharging end face, and the spinneret orifice of described charging end face is in
Circle, the spinneret orifice of described discharging end face is in I-shaped.
Charging aperture is symmetrically arranged with the feed zone face of described spinnerette body, short row is divided into charging aperture longitudinal arrangement
With long row, short row and long row are arranged at intervals successively in charging hole, short 4 ~ 14 charging holes of behavior, long 5 ~ 15 charging holes of behavior.
Rounded, the circular a diameter of 3.0 ~ 5.9mm of the described spinneret orifice for feeding end face, the discharge end of spinnerette body
Face is provided with the discharging opening corresponding with gating location, quantity, by through spray between corresponding discharging opening and charging aperture
The Zhong Tongduan roads of filament plate body are linked, and a diameter of 0.95mm ~ 3.95mm of section is led in material passing passage.
The thin diameter section draw ratio of described discharging end face is 8 ~ 16, and its end face is in I-shaped, the width of I-shaped body
For 0.15 ~ 0.48mm.I-shaped body corner is roundlet, and the shape size of described four roundlets is identical and the center of circle is positioned at pros
On the corner of shape.
Before use, spinneret, screen pack and distribution plate are first assembled into spinning pack, because whole spinneret is right for rule
The design of title property, assembling process is simple, and deflection error problem is not present in round rectangle design.
The beneficial effects of the invention are as follows：High polymer after this profile spinneret spinneret, accumulate to form " work " word by its fibre section
Shape, I-shaped are internally formed two halves cavity structure and make it have larger specific surface area so as to add capillarity, improve
The moisture absorbing and sweat releasing and gas permeability of fabric；And extraction area is effectively increased in process of production, the white oil of swelling can be made faster
Extract, reduce in drawing process produce lousiness phenomenon.
