Description
Technical field
The invention belongs to spinneret fields, are related to a kind of porous spinneret of melting spinning filament, in particular to a kind of spinneret
The porous spinneret of the melting spinning filament of hole oval shaped arrangements.
Background technique
Polyethylene terephthalate (PET) has high mechanical properties, wear-resisting, creep resistant and electrical insulation capability good etc. special
Point, and abundant raw material are to develop most rapid, the fine kind of the maximum conjunction of production capacity in recent years.PET superfine fibre is that a kind of performance is excellent
Good, unique style high-tech, high value added product, it is anti-in medium-to-high grade fabric, building, biomedicine, industrial filter, military affairs
The fields such as shield, environmental protection present wide application prospect.There are many method for preparing PET superfine fibre, wherein melt spinning
Method is one kind more in current industrial production application.
There are many parameter during melt spinning, these parameters determine the course of fiberizing and spin fiber structure and
Performance is exactly the fiber of performance needed for being made by controlling these parameters in production.It can will be controlled in production according to technical process
The main spinning parameter of system is summarized as melting condition, spinning conditions, condition of cure, wrapping wire condition etc., and wherein strand cools and solidifies
Condition has conclusive influence to fibre structure and performance, raw for the cooling velocity and its uniformity for controlling polyester fondant thread
Cooling blowing is generally taken in production.Cooling blowing can accelerate the cooling velocity of melt stream, be conducive to improve spinning speed；Reinforce
The convection current of strand surrounding air keeps ectonexine strand cooling uniformly, to create condition using porous spinneret；Cooling blowing can
Make as-spun fibre Quality advance, tensile property improves, and is conducive to the production capacity for improving equipment.
Experimental branch line all uses cross air blasting as the type of cooling for a long time, and energy consumption accounts for long filament production cost very
Most of, as people increasingly improve chemical fibre performance and quality requirements, the exploitation of chemical-fibres filaments new product is to high added value
Fibre in differentiation direction is developed, it is desirable that higher cooling blowing condition then proposes circular blow wind apparatus.Circular blow wind apparatus is not only
Have a uniform advantage of every synnema wind-engaging, and energy consumption is compared to lower, effective solution cross air blasting since blowing area is big and
Caused by wind energy lose problem.
During the spinning process, although circular blow wind has apparent advantage, the cooling of porous yarn can not be well solved
Uneven problem.Since spun silk is after round spinneret extrusion, by ring wind quenching, due to round spinneret circle number compared with
It is more, so that circular blow wind hardly enters innermost layer, lead to that the silk of innermost layer may be also uncolled after cooling in outermost silk,
To which the problems such as fiber number is irregular, and intensity is irregular, uneven dyeing occurs in resulting silk, the subsequent further processing to silk is caused to occur
Difficulty.
Summary of the invention
The purpose of the present invention is overcoming the problems, such as that existing spinneret sweeps that blow down inhomogeneous cooling even in circular blow wind, and realize big
The production spinning of scale, provides a kind of novel spinneret plate.
In order to achieve the above objectives, the technical solution adopted by the present invention are as follows:
A kind of porous spinneret of melting spinning filament, the arrangement mode of spinneret orifice is oval shaped arrangements on the spinneret,
The oval shaped arrangements refer to that the hole center of spinneret orifice is located on concentration ellipse, and the concentration ellipse is that series is oval, all ellipse
Round long axis is conllinear, and short axle is conllinear.
As a preferred technical scheme:
Spinneret as described above, the spinneret orifice be arranged as long axis and/or short axle is symmetrical.
The ratio of spinneret as described above, elliptical long axis and minor axis length is 1.3~1.8.It is effective when spinneret
For area phase simultaneously as the perimeter of ellipse is greater than circular perimeter, the number of plies of spinneret orifice oval shaped arrangements is less than circular arrangement
The number of plies, the hole counts of spinneret orifice oval shaped arrangements is greater than the hole count of circular arrangement, and therefore, spinneret orifice oval shaped arrangements are conducive to ring
The cooling of blowing, improves the cooling efficiency of circular blow wind, and the fibre property of preparation is also more excellent.The ratio of long axis and minor axis length
Closer to 1, ellipse is more similar to justify, and the difference of cooling efficiency and cooling effect is little；Long axis and the ratio of minor axis length are
When 1.3, cooling effect is significantly improved, and individual pen hole count increase accordingly 16%；It is cooling when long axis and the ratio of minor axis length are 1.8
Effect improves larger, and individual pen hole count increase accordingly 33%, and in the case of identical hole count, oval shaped arrangements of the invention compare conventional concentric
The circle number of circle best-fit is reduced, and is easy to cooling wind and is blown through, makes the fiber cooling condition of Internal and external cycle more evenly；Long axis and minor axis length
When ratio is greater than 1.8, ellipse is partial to form flat shape, is not easy to punch, cooling no longer increases.Therefore, it is
The ratio for arranging elliptical long axis and minor axis length is 1.3~1.8, can reach higher cooling efficiency and preferable cooling effect
Fruit.
Spinneret as described above, the guide hole diameter that the spacing of adjacent spinneret orifice is more than or equal to spinneret orifice add 1.5mm.
Spinneret as described above, the spinneret are round spinneret or elliptical spinneret plate.
Spinneret as described above, the diameter of the circle spinneret and the difference of serial oval maximum long axis length are big
In 10mm, the difference of the elliptical spinneret plate and the oval maximum long axis length of series is greater than 10mm.
Spinneret as described above, the guide hole diameter of the spinneret orifice are 1.5~2.5mm.
The spinneret hole count of spinneret as described above, the spinneret is more than or equal to 192.
Spinneret as described above, the cross-sectional shape of the spinneret orifice of the spinneret be circle, square, diamond shape,
"-" type, triangular form, trilobal cross, hollow type or platypelloid type.
The utility model has the advantages that
1) arrangement mode of spinneret orifice is oval shaped arrangements on spinneret of the invention, and the effective area of spinneret is identical
When, the number of plies of spinneret orifice oval shaped arrangements is less than the number of plies of circular arrangement, and circular blow wind is easier to blow through dynamic analysis of spinning, dynamic analysis of spinning
Cooling effect it is more preferable, the fibre property of preparation is also more excellent.
2) arrangement mode of spinneret orifice is oval shaped arrangements on spinneret of the invention, and the effective area of spinneret is identical
When, the hole count of spinneret orifice oval shaped arrangements is greater than the hole count of circular arrangement, and oval shaped arrangements can be realized a greater degree of cooling,
Significantly improve cooling efficiency.
