Abstract
The utility model relates to a spinneret plate. The spinneret plate comprises a round spinneret plate body, a plurality of spinneret orifices penetrating through the spinneret plate body are formed in the spinneret plate body, the spinneret orifices are composed of guide holes and capillary holes, wherein the guide holes and the capillary holes are coaxial. The spinneret plate is characterized in that the cross section of each guide hole is in a double-curve shape, a guide groove is formed between every two adjacent guide holes, and two free ends of the guide grooves extend into the guide holes; the cross section of each capillary hole is in a cone shape, and regularly-distributed protruding blocks are arranged on inner walls of the capillary holes. The spinneret plate is simple in structure and easy to machine, shortens the standing time of melt at an inlet area, reduces possibilities of dead corners and avoids degradation and generation of carbonization, is capable of being used for spinning hollow, fluffy, elastic and soft fibers with three-dimensional curling effects and can be widely applied to manufacturing of various textile articles.
Description
Technical field
The utility model relates to a kind of spinning accessory, relates in particular to a kind of spinnerets.
Background technology
Spinnerets claims again spinning cap, and the Main Function of spinnerets is that high polymer molten or solution are transformed into the thread with particular cross section by micropore, and through wind, cooling or coagulating bath is solidified to form slice, thereby affects fiberizing.
Current spinnerets has plain edition and abnormity and composite spinneret, and the section of plain edition spinning fibre is circular, and the section of the fiber of different in nature spinnerets spinning is non-circular, and composite spinneret is to manufacture composite fibre.
For needs, spin out conjugate effect and the fluffy whippy fiber of hollow, the spinnerets of above three types can't spin out at present.
For existing spinnerets, melt is when entering inlet region, and elasticity can be larger, there will be the phenomenon at dead angle, produces degraded and carbonization, has affected fiberizing effect.
Utility model content
The utility model has overcome the deficiencies in the prior art, and a kind of spinnerets simple in structure is provided, this spinnerets can spin out there is conjugate effect, fluffy and high resilience, soft fiber, and there will not be dead angle in spinning process.
For achieving the above object, the technical solution adopted in the utility model is: a kind of spinnerets, comprise circular jetting filament plate plate body, described spinnerets plate body is provided with the spinneret orifice that several run through described spinnerets plate body, described spinneret orifice is comprised of coaxial guide hole and pore, it is characterized in that: the cross section of described guide hole is hyperbola, between described adjacent passages, be provided with guide groove, two free ends of described guide groove extend in described guide hole, the cross section of described pore is conical, and described pore inwall is also provided with the protruding block of regular distribution.
In preferred embodiment of the utility model, further comprise that described spinneret orifice is circular concentric and is arranged on described spinnerets plate body, between the above adjacent passages of same circumference, be provided with guide groove.
In preferred embodiment of the utility model, further comprise that two free ends of described guide groove seamlessly transit to described guide groove.
In preferred embodiment of the utility model, further comprise that described protruding block distributes in the shape of a spiral at described pore inwall.
The utility model has solved the defect existing in background technology, spinneret plate structure of the present utility model is simple, easily processing, shortened the time of staying of melt in inlet region, reduce to occur the possibility at dead angle, avoided the generation of degraded and carbonization, can spin out there is conjugate effect, the fluffy and high resilience of hollow, soft fiber, can be widely used in and manufacture multiple textile product.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Fig. 2 is spinneret orifice cutaway view of the present utility model;
In figure: 1, spinnerets body, 2, spinneret orifice, 21, guide hole, 22, pore, 3, guide groove, 4, protruding block.
The specific embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As depicted in figs. 1 and 2, a kind of spinnerets, comprise circular spinnerets plate body 1, can select the stainless steel high temperature resistant, corrosion-resistant, mechanical strength is large to manufacture spinnerets plate body 1, spinnerets plate body 1 is provided with several spinneret orifices 2, spinneret orifice 2 of the present utility model is circular concentric and is arranged on spinnerets plate body 1, easily processing.Spinneret orifice 2 is comprised of coaxial guide hole 21 and pore 22, as shown in Figure 2, the cross section of guide hole 21 is hyperbola, pore 22 cross sections are conical, the guide hole 21 of hyperboloid shape and conical pore 22 can be controlled the shear velocity of melt flows, make melt obtain larger pressure differential, thereby the fiber filaments that spinneret orifice 2 is blown out is separated from each other, can be not bonding.21 of adjacent passages are provided with guide groove 3, and two free ends of guide groove 3 extend in guide hole 21.Pore 22 inwalls are also provided with the protruding block 4 of regular distribution.
As preferred embodiment of the present utility model, guide groove 3 is located on same circumference between adjacent passages 21, and two free ends of guide groove 3 seamlessly transit to described guide hole 21.On the basis of guide hole 21, establish guide groove 3 newly, can increase melt potential energy and mobility, reduce the elasticity energy that melt obtains in inlet region, reduce the contact-making surface at the front net of plate and the spinnerets back side, reduce as far as possible the possibility that occurs dead angle, also shortened the time of staying of melt, avoided the generation of degraded and carbonization, guaranteed the effect of fibre forming simultaneously.
Further, protruding block 4 distributes in the shape of a spiral at pore 22 inwalls, and melt-flow, through protruding block, can form on surface three-dimensional rolled efficiency.
Spinneret plate structure of the present utility model is simple, easily processing, shortened the time of staying of melt in inlet region, reduce to occur the possibility at dead angle, avoided the generation of degraded and carbonization, can spin out there is conjugate effect, the fluffy and high resilience of hollow, soft fiber, can be widely used in and manufacture multiple textile product.
According to desirable embodiment of the present utility model, be enlightenment above, by above-mentioned description, related personnel can, not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on description, must determine technical scope according to claim scope.
