Abstract
A spinneret plate for weaving hollow fiber is provided, in particular to a spinneret plate for weaving hollow fiber with high speed, which is characterized in that: spinneret holes on the spinneret plate are distributed in ring shape, which are composed of guiding holes and spinneret pores; the section of the spinneret pores is the discontinuous ring body composed of at least two segments of arc slits. The spinneret plate with the hole shaped as above adopted has the advantages of excellent fluidity of fused mass, normal fused mass expansion at outlet of the spinneret hole, uneasy for break down of fused mass, proper hollow degree of the hollow fiber produced, reliable hollow size and regulated section of the strand silk, which, after been made as textile, is warm, puff, light and comfortable.
Description
Relate to the field:
The utility model relates to a kind of spinnerets that spins doughnut, is in particular a kind of high-speed spinning tubular filament fiber spinnerets.
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 DT silk that is fit to is produced, and tubular filament is of poor quality, and production efficiency is lower, and production cost is higher.
Summary of the invention:
The purpose of this utility model is to provide a kind of spinnerets that adopts the spinning doughnut that High-speed Spinning Production explained hereafter tubular filament fiber uses.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of high-speed spinning tubular filament fiber spinnerets, the spinneret orifice on the spinnerets distributes in the form of a ring, and spinneret orifice is made up of a guide hole and a spray silk pore, and the cross sectional shape of a described spray pore is the ring bodies of the interruption be made up of two sections circular arc slits at least.
The purpose of this utility model can also further realize by following technical measures:
Aforesaid a kind of high-speed spinning tubular filament fiber spinnerets, the cross sectional shape of wherein said spray silk pore are the ring bodies of the interruption of two sections or three sections circular arc slit compositions.
Aforesaid a kind of high-speed spinning tubular filament fiber spinnerets, the transversal face width b of wherein said each section of spray silk pore circular arc slit is 0.06-0.12mm, gap L is 0.06-0.12mm between two sections adjacent circular arc slits.
Aforesaid a kind of high-speed spinning tubular filament fiber spinnerets, wherein said each circular arc slit two ends are arc, circular arc slit two ends circular arc R is 0.03-0.06mm.
Aforesaid a kind of spinning tubular filament fiber spinnerets, the height h of wherein said spray silk pore is 0.4-0.9mm.
Use this spinnerets to produce polyester POY fiber, winding speed can reach 2500-3600m/min, and winding speed can reach 3800-4900m/min when producing FDY.
The utility model is compared with existing long filament production technology, spinneret orifice is made up of the guide hole of circle and circular arc slit two parts that are divided into three sections or two sections, the effect of guide hole is to enter micropore with guiding the melt continuously smooth, the high polymer molten that is viscous state is by behind the circular arc slit, because the elasticity of high polymer molten, the high polymer of extruding from the circular arc slit can closed adhesion form blind bore between adjacent circular arc slit, change melt thread into hollow section, drawn, cooling, processes such as curing become doughnut, form the POY spinning cake through reeling.Use the spinnerets of this shape pass to have that melt flowability is good, the expanded phenomenon of spinneret orifice exit melt normal, be difficult for making melt fracture, moderate, the hollow dimensionally stable of the doughnut degree of hollowness of producing, strand cross section regularity is good.The POY that produces can be used for directly weaving (directly use or with other fibers plying) or is used for reprocessing (as being processed into DTY, ATY, DT etc.).After making fabric, warmth retention property is good, and fluffy sense is strong, fabric weight is light, comfortable and easy to wear.
Description of drawings:
Fig. 1 is the structural representation of a preferred embodiment of the utility model;
Fig. 2 is the A-A cross-sectional view of Fig. 1;
Fig. 3 is that the B of Fig. 2 is to structural representation.
The specific embodiment:
As Figure 1-3, the utility model spinnerets 1 can be made by metal material, be provided with spinneret orifice 4 on it equably, this spinneret orifice 4 is vertical with spinning plate surface, this spinneret orifice 4 is made up of the guide hole 2 and spray silk pore 3 two parts of circle, and this guide hole mouth and this spray silk pore aperture are divided into the side, two ends of spray plate body.The effect of guide hole 2 be guiding melt continuously smooth enter micropore, the high polymer molten that is viscous state is transformed into by the circular arc slit and has the melt thread that the cross section is a hollow form, processes such as drawn, cooling, curing become doughnut.Spinneret orifice on the spinnerets 1 distributes in the form of a ring, and its distribution can be that circle distribution, rhombus distribute or other distribution forms.The number of turns that spinneret orifice 4 is arranged can be set according to the quantity of spinneret orifice, the requirement of production kind dpf number.Spinneret orifice 4 is made up of guide hole 2 and spray silk pore 3, guide hole diameter D=0.25-0.30mm, and spray silk pore height is h=0.4-0.9mm.The cross sectional shape of spray silk pore 3 is the ring bodies of the interruption be made up of two sections circular arc slits at least.The cross sectional shape of spray silk pore 3 is the ring bodies of the interruption of two sections or three sections circular arc slit compositions.The transversal face width of spray silk pore each section circular arc slit is b=0.06-0.12mm, and the gap is L=0.06-0.12mm between two sections adjacent circular arc slits.Each circular arc slit two ends is an arc, circular arc slit two ends circular arc R=0.03-0.06mm.Circular arc slit outside diameter D1=0.60-0.12mm is convenient to the spinnerets capillary processing, and can make the two or three part melts of extruding after going out spinnerets, and is adhered to one another easily, forms doughnut.Can adopt high-speed spinning long filament production Technology, the POY winding speed is 2500-3600m/min, and winding speed is 3800-4900m/min when producing FDY.When adopting high-speed spinning long filament production Technology, adjusting process parameter reasonably, the degree of hollowness that can make fiber is in the 8-30% scope.
