Abstract
The utility model discloses a cross profile spinneret, which comprises a spinneret body and spinneret orifice distributed on the spinneret body and is characterized in that the cross section of each spinneret orifice is formed by arranging four isosceles trapezoids with upper bases facing a circle center and four semicircles in a circumferential array manner, and each semicircle is connected with the lower base of each isosceles trapezoid. Compared with the prior art, the cross profile spinneret has the advantages that by adoption of the specific arrangement manner of the spinneret orifices, profile yarns can be cooled more uniformly and sufficiently under a cross air blow condition, in addition, the manner of combining the isosceles trapezoids with the semicircles is adopted for the cross section of the spinneret orifices, the distribution uniformity of fusant can be improved further, and thus, the extrusion swelling phenomenon of the fusant is alleviated effectively.
Description
Technical field
The utility model relates to a kind of cross special-shaped spinnerets, especially a kind of spinnerets of producing cross special-shaped polyester filament.
Background technology
There is the extrusion swelling phenomenon in polyester fondant after going out spinneret orifice; Obtain desirable degree of profile and must strengthen special-shaped spinneret orifice blade length-width ratio; But excessive spinneret orifice blade length-width ratio is distributed melt in micropore uniformity variation, melt can not arrive the top of blade uniformly, and the top form can not get good maintenance; Be prone to produce melt fracture; Influence stability of spinning process, and spinnerets processing and the difficulty of cleaning increasing, also is limited through increasing spinneret orifice blade length-width ratio to the influence of degree of profile in addition.For this reason, develop a kind of novel cross spinnerets and satisfy practical demand, imperative.
The utility model content
The utility model technical problem to be solved is the spinnerets that a kind of wire vent efficient height, steady quality is provided to the above-mentioned state of the art, is prone to cleaning.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: cross special-shaped spinnerets; Include the spinnerets body and be distributed in the spinneret orifice on the aforementioned spinnerets body; The cross section that its sign is said spinneret orifice is the circumferential array by four upper bases towards the isosceles trapezoid in the center of circle and four semicircles and forms, and said semicircle is connecting going to the bottom of aforementioned isosceles trapezoid.
Said spinneret orifice on said spinnerets body, can be square or rhombus is evenly distributed.
Further, evenly distributed on the said spinnerets body with rhombus, and this diamond crossing acute angle angle is 60 °～80.
As preferably, going to the bottom of said isosceles trapezoid longly equates that with said semicircle diameter length the high length of said isosceles trapezoid is the twice of said semicircle diameter length.Further, the long 0.1mm that is that goes to the bottom of said isosceles trapezoid, upper base is long to be 0.075mm.
Compared with prior art; The advantage of the utility model is: the spinneret orifice on the utility model adopts specific arrangement mode; Can make shaped filaments under the lateral blowing condition, cooling more evenly, fully trapezoidally adds semicircle mode and the spinneret orifice cross section is taked; The uniformity that melt is distributed further improves, and has effectively alleviated the extrusion swelling phenomenon of melt.

Fig. 2 is the enlarged drawing of spinneret orifice among Fig. 1.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2; Cross special-shaped spinnerets in the present embodiment includes spinnerets body 1 and is evenly distributed on the spinneret orifice 2 on the spinnerets body 1; Be evenly distributed on the spinnerets body 1 spinneret orifice 2; The cross section of spinneret orifice 2 is the circumferential array by four upper bases towards the isosceles trapezoid in the center of circle and four semicircles and forms, and semicircle is connecting going to the bottom of isosceles trapezoid.Each blade that is spinneret orifice 2 is formed by a semicircle and an isosceles trapezoid; Semicircle diameter and the isosceles trapezoid long L2 that goes to the bottom equates; The high H of isosceles trapezoid is 2 times of semicircle diameter, is further preferred version, and the long L1 of isosceles trapezoid upper base is 0.075mm; The long L2 that goes to the bottom is 0.1mm, and preferred specification is 36 holes, external diameter 75mm.Adopt gradually wide blade aperture and semicircle blade nose end, the uniformity that melt distributes improves, and has effectively alleviated the extrusion swelling phenomenon of melt; Compare with the cross special-shaped spinnerets of routine; This cross special-shaped spinnerets micropore blade length-width ratio reduces, and reduce at spinneret orifice corner angle, dead angle, and the flow resistance of spinning polyester fondant reduces; The degree of profile of cross special-shaped polyester filament, stability of spinning process all improve greatly, and fibre section and cross are more approaching.With diamond array, the acute angle angle of preferably intersecting during diamond array is 60 °～80 ° to spinneret orifice 2 on spinnerets body 1, and such design can make shaped filaments under the lateral blowing condition, the cooling more evenly, more abundant.
