The utility model is characterized in that the section shape of the spinneret capillary holes is composed of three sections of Y-shaped slits; the upper part of every section of Y-shaped slit is an inwards-concave circular arc slit; the lower part is a linear slit which is positioned in the middle part of the circular arc slit and is connected with the outer circumference of the circular arc slit. An intermittent circular arc is formed at intervals between two endpoints of the circular arc slit at the upper part of every section of the Y-shaped slit. The hole-shaped spinneret plate has the advantages of superior flowing performance of melting bodies, normal expanded phenomenon of the melting bodies at outlet parts of the spinneret holes, difficult rupture of the melting bodies; moderate hollow degree of produced hollow fibers, stable hollow dimension, etc.
Description
Technical field
The utility model relates to a kind of spinnerets of producing doughnut, particularly a kind of spinnerets of producing doughnut.
Background technology
In the prior art, the doughnut speed of production of producing with conventional spinning method is low, and the scope of application is restricted, and general road, the work back TD silk that is fit to is produced, and doughnut is of poor quality, and production efficiency is low, the production cost height.
Summary of the invention
The purpose of this utility model is to provide a kind of spinnerets that adopts High-speed Spinning Production explained hereafter fiber to use.
The purpose of this utility model realizes by following technical solution:
A kind of spinnerets of suitable production doughnut, spinneret orifice on the spinnerets distributes in the form of a ring or diamond shape distributes or other distribution forms, spinneret orifice is made up of guide hole and spray silk capillary, the cross sectional shape of its described spray silk pore is that three sections Y shape slits are formed, the top of Y shape slit is the circular arc slit of indent, the bottom is the linear slit, the linear slit is positioned at the middle part of circular arc slit, and join with its excircle, form an annulus that is interrupted with certain clearance between the two-end-point of the top circular arc slit of each section Y slit.
The purpose of this utility model can also be come further accomplished by following technical measures:
Aforesaid a kind of spinnerets of producing doughnut, each end points of wherein said Y shape slit is circular arc.
The spinnerets spinnerets of aforesaid a kind of suitable production doughnut, wherein said circular arc slit two ends circular arc R is 0.03-0.06mm, circular arc slit width B is 0.06-0.12mm, linear slit end face circle r is 0.03-0.05mm, linear slit width b is that 0.06-0.10mm. circular arc slit outer diameter D 1 is 0.60 for 0.03-0.05mm, linear slit width b is 0.06-0.10mm, circular arc slit outer diameter D 1 is 0.60-0.12mm, and gap L is 0.06-0.09mm between two sections circular arc slits.Linear slit end points is to spinneret orifice centre-to-centre spacing H=0.75-1.20mm.
The spinnerets of aforesaid a kind of suitable production doughnut, wherein said guide hole diameter D is 0.25-0.40mm, spray silk pore height H is 0.4-0.9mm.
The utility model is compared with existing fiber production technology, spinneret orifice is by the guide hole of circle and be divided into three sections circular arc slits and close linear slit two parts and form, the effect of guide hole is that guiding enters micropore with melting the body continuously smooth, the high polymer that is viscous state melt body by the circular arc slit after because the elasticity that high polymer melts body, the high polymer of extruding from the circular arc slit can closed adhesion form blind bore between adjacent circular arc slit, change have a hollow section melt the body thread, drawn, cooling, processes such as curing become doughnut, form the POY spinning cake through reeling.Use the spinnerets of this shape pass have the liquid flowability of melting can good spinneret orifice exit melt the expanded phenomenon of body normal, melt body and be difficult for breaking, the doughnut degree of hollowness of producing is moderate, advantages such as hollow dimensionally stable.
