Abstract
The utility model relates to a spinneret plate for producing hollow fibers. The spinneret plate for producing hollow fibers comprises a plate body; the plate body is provided with guide holes and spinneret capillary holes; the cross-section shapes of the spinneret capillary holes are intermittent ring forms consisting of three circular arc slits; the central parts of inner surfaces of the circular arc slits are provided with protruding rectangles; or the cross-section shapes of the spinneret capillary holes are intermittent triangles consisting of three rectangular slits with two circular arc ends; and the central parts of the inner surfaces of the rectangular slits are provided with protruding rectangles. The spinneret plate has the advantages that due to the existence of the protruding rectangles, the monofilament cross section of the spun hollow fibers not only is a closed loop, but also the inner side of the closed loop is provided with protrusions which are distributed at intervals; the protrusions can play a filling effect; when the hollow fibers are extruded by an external force, deformation and flattening can be prevented, so that the fibers always keep the hollow shape, and the deserved performances of the spinneret plate for producing hollow fibers are developed.
Description
Technical field
The utility model relates to a kind of spinnerets, especially a kind of spinnerets for the production of doughnut.
Background technology
Along with the progress of society, chemical fibre industry has had larger development, and existing doughnut easily is crushed because of extruding, therefore production equipment is had higher requirement.
In the present daily life, the use of doughnut is more and more, and doughnut has lighter warmer, plentiful softness, dry and comfortable wet effect is very popular.In the doughnut of producing at present, the hollow space of most doughnut all is circular, because circular hollow space is in the situation that be subject to external force easily because push the situation that is crushed and occurs being out of shape, thereby affects the quality of fiber; So that doughnut does not reach original design performance; So that the result of use of doughnut reduces greatly.
Existing hollow fibre spinneret generally comprises the spinnerets body and is distributed in regularly a plurality of spinneret orifices on the spinnerets body, wherein spinneret orifice further comprises guide hole and spray silk pore two parts, guide hole is generally circle, its effect is that the guiding spinning melt enters spray silk pore continuously and gently, in order to increase guiding function, the rear and front end of guide hole generally also is provided with bullport.Spray silk pore is the key position of melt forming, existing spray silk pore cross sectional shape is the annular of the interruption that is comprised of three sections circular arc slits, its shortcoming is: the doughnut of producing is in the situation that be subject to external force and easily be crushed because of extruding, thereby loses original performance.
Therefore be necessary existing spinnerets for the production of doughnut is improved.
Summary of the invention
The purpose of this utility model is the spinnerets of a kind of doughnut of designing for the deficiency of understanding above-mentioned technology, utilizes the doughnut of this spinnerets production in the situation that be subject to external force and be difficult for being crushed.
The spinnerets for the production of doughnut that the utility model is designed, comprise plate body, be provided with guide hole and spray silk pore at plate body, the cross sectional shape of described spray silk pore be the annular of the interruption that is comprised of three sections circular arc slits, is provided with protruding rectangle in the center of circular arc slit inner surface.
As preferably, the circular arc slit width is 0.25mm, is spaced apart 0.10mm between the circular arc slit, and the length of described rectangular preiection is 0.10mm.
The spinnerets for the production of doughnut that the utility model is designed, its beneficial effect is: owing to being provided with the rectangle of projection in the center of circular arc slit inner surface, the doughnut monofilament cross section of ejection not only is the annulus of a sealing like this, and be provided with the projection that is spaced apart in the inboard of annulus of sealing, this projection can play filling effect, when doughnut is subject to the external force extruding, can prevent distortion, become flat, so that fiber remains hollow form; Bring into play its due performance, thereby so that lighter warmer, the plentiful softness of this doughnut, dry and comfortable wet, result of use is better.
The spinnerets for the production of doughnut that the utility model is designed, comprise plate body, be provided with guide hole and spray silk pore at plate body, the triangle of the interruption that the rectangle slit that the cross sectional shape of described spray silk pore is is circular arc by three two ends forms is provided with protruding rectangle in the center of rectangle slit inner surface.
As preferably, the rectangle slit width is 0.25mm, is spaced apart 0.10mm between the rectangle slit, and the length of described rectangular preiection is 0.10mm.
The spinnerets for the production of doughnut that the utility model is designed, its beneficial effect is: owing to being provided with the rectangle of projection in the center of circular arc slit inner surface, the doughnut monofilament cross section of ejection not only is three square rings of a sealing like this, and be provided with the projection that is spaced apart in the inboard of three square rings of sealing, this projection can play filling effect, when doughnut is subject to the external force extruding, can prevent distortion, become flat, so that fiber remains hollow form; Bring into play its due performance, thereby so that lighter warmer, the plentiful softness of this doughnut, dry and comfortable wet, result of use is better.
