Abstract
The utility model relates to anti-squash hollow fibers and a spinneret plate for producing the hollow fibers. The sections of the anti-squash hollow fibers are circular externally and square internally. The spinneret plate comprises a spinneret plate body and a plurality of spinneret orifices regularly distributed on the spinneret plate body, wherein each spinneret orifice comprises a guide hole and a spinneret pore; and particularly, the section of each spinneret pore is in the shape of a discontinuous ring which is formed by three sections of arc-shaped slits, and the inner side surfaces of two ends of all the arc-shaped slits are protruded to form a semi-circle. As the sections of the fibers disclosed by the utility model are designed to be circular externally and square internally, compared with fibers with circular hollow parts, the squashed degree of the fibers disclosed by the utility can be reduced effectively, and thus the fibers can achieve desired effects according to design. By virtue of the specific design of the spinneret pores of the spinneret plate, the spinneret plate can successfully produce the hollow fibers with the sections being circular externally and square internally; in addition, the spinneret plate has a simple structure.
Description
Technical field
The utility model belongs to the doughnut production technical field, particularly a kind of doughnut of anti-collapse and be exclusively used in the spinnerets of the doughnut of producing this anti-collapse.
Background technology
In the existing doughnut of producing, the hollow space of most doughnut all is circular, because circular hollow space can form the situation that is crushed easily under the effect that receives external force, makes that the original intention of design can not be accomplished.
Known, spinnerets is the critical component of device for spinning.Existing spinnerets generally comprises the spinnerets body and is distributed in a plurality of spinneret orifices on the spinnerets body regularly, and wherein spinneret orifice further comprises guide hole and spray silk pore two parts.Guide hole is generally circle, and its effect is that the guiding spinning melt gets into spray silk pore continuously and gently, and in order to increase guiding function, the rear and front end of guide hole generally also is provided with bullport.A spray silk pore is the key position of melt forming, need carry out special design to a spray silk pore to the doughnut of specific sectional shape.
Summary of the invention
The utility model technical problem to be solved is the deficiency that overcomes prior art, and a kind of doughnut of anti-collapse is provided.
The utility model also will provide a kind of spinnerets that is exclusively used in the doughnut of production anti-collapse simultaneously.
For solving the problems of the technologies described above, a kind of technical scheme of the utility model is:
A kind of doughnut of anti-collapse, the cross section of this fiber is cylindrical, interior side's hollow shape.
The another technical scheme that the utility model is taked is:
A kind of spinnerets of above-mentioned doughnut production usefulness; It comprises the spinnerets body and is distributed in a plurality of spinneret orifices on the spinnerets body regularly; Each spinneret orifice comprises guide hole and spray silk pore; Particularly, the annular of being interrupted of cross sectional shape for forming of described spray silk pore by three sections circular arc slits, the two ends inner surface of each described circular arc slit convexes to form semicircle.
Further embodiment according to the utility model: described a plurality of spinneret orifices on the spinnerets body in the form of a ring, rhombus or distributed rectangular.
According to a concrete aspect of the utility model, the radius r of said semicircle is 0.06mm～0.09mm.The width w of described circular arc slit is 0.3～0.5mm.Spacing d between adjacent two sections said circular arc slits is 0.14～0.18mm.Preferably, the spacing d between adjacent two sections circular arc slits equates.
In a specific embodiment of the utility model, the spacing d between adjacent two sections said circular arc slits equates, and spacing d is 0.14～0.18mm, and the width w of circular arc slit is 0.3～0.5mm; The radius r of semicircle is 0.06mm～0.09mm; The inside diameter D of spray silk pore is 0.07～0.85mm.
Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:
The utility model is designed to cylindrical, interior side's shape with the fibre section, compares for circular fiber with hollow space, can effectively reduce the degree that is crushed, and makes fiber to obtain expected effect according to design.
The utility model designs through the spray silk pore to spinnerets especially, makes it possible to success and produces the doughnut that the cross section is cylindrical, interior square shape; In addition, the spinnerets of the utility model is simple in structure.
Description of drawings
Below in conjunction with accompanying drawing and concrete embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation according to the spinnerets of the utility model;
Fig. 2 is the cross-sectional schematic of single spinneret orifice;
Fig. 3 is the sectional view according to the spray silk pore of the utility model;
Wherein: 1, spinnerets body; 2, spinneret orifice; 20, guide hole; 21, spray silk pore; 210, circular arc slit; 211, semicircle.
The specific embodiment
As shown in Figure 1, comprise spinnerets body 1 and be distributed in a plurality of spinneret orifices 2 on the spinnerets body 1 in the form of a ring according to the spinnerets of present embodiment.As shown in Figure 2, spinneret orifice 2 further comprises guide hole 20 and spray silk pore 21.Guide hole 20 is circular, and its effect is that the guiding spinning melt gets into spray silk pore 21 continuously and gently, and in order to increase guiding function, the rear and front end of guide hole 20 is provided with bullport.As shown in Figure 3, spray silk pore 21 is the ring bodies of being made up of three sections circular arc slits 210 that is interrupted, and the two ends inner surface of each circular arc slit 210 convexes to form semicircle 211.
Take the spinnerets of structure; Through the guiding of guide hole 20, the high polymer molten that is viscous state evenly and gently gets into the circular arc slit 210 of spray silk pore 21, because the elastic reaction of high polymer molten; The high polymer of extruding from three sections circular arc slits 210 can adhesion between adjacent slit; Closure, the middle part forms hollow, becomes the melt thread with hollow section.This melt thread drawn, cooling, processes such as curing just become the doughnut that the cross section is cylindrical, interior side.
Further, the specification of spinneret orifice can be selected according to reality fiber to be processed.In this example, relevant parameter is: the spacing d between adjacent two sections said circular arc slits 210 is all identical, and is 0.14～0.18mm, and the width w of circular arc slit 210 is 0.3～0.5mm; The radius r of semicircle 211 is 0.06 mm～0.09mm; The inside diameter D of spray silk pore 21 is 0.07～0.85mm.
