Abstract
The utility model relates to an asymmetric pass spinneret, include: the plate body is provided with a plurality of spinneret orifices; each spinneret orifice comprises a guide hole and a micropore which are communicated with each other; the cross section of the micropore comprises a circular groove positioned in the center of the micropore; the circular groove extends outwards to form a first linear groove and a second linear groove; the first linear groove and the second linear groove are perpendicular to each other; the cross section of the extruded fiber spinning is circular, and the first strip and the second strip are connected with the circular cross section and are perpendicular to each other, the combination of the patterns is an asymmetric pattern, and asymmetric stress is generated during cooling shrinkage after fiber spinning, so that a better crimping effect can be obtained.
Description
Technical Field
The utility model relates to a spinneret specifically is an asymmetric pass spinneret.
Background
After the traditional fiber spinning is cooled, the uniform shrinkage to the middle part can be caused due to the existence of stress, and the curling effect is not obvious;
in conclusion, how to obtain fiber spinning with obvious crimping effect becomes a problem which needs to be solved urgently by researchers of the company.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: how to obtain fiber spinning with obvious crimping effect;
in order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model relates to an asymmetric pass spinneret, include: the plate body is provided with a plurality of spinneret orifices; each spinneret orifice comprises a guide hole and a micropore which are communicated with each other; the cross section of the micropore comprises a circular groove positioned in the center of the micropore; the circular groove extends outwards to form a first linear groove and a second linear groove; the first linear groove and the second linear groove are perpendicular to each other;
in the scheme, the section of the fiber spun by the spinneret plate is in a combined shape of the first straight line groove, the second straight line groove and the circular groove, the combined shape is an asymmetric pattern, and due to the asymmetric appearance, asymmetric stress is generated during cooling shrinkage after the fiber is spun, so that a better curling effect can be obtained.
The utility model has the advantages that: the utility model relates to an asymmetric pass spinneret, the fibre spinning cross-section of extruding in this scheme be circular and be connected first strip, second strip with circular, first strip, second strip mutually perpendicular, the combination of foretell figure is asymmetric figure, produces asymmetric stress when cooling shrink after the fibre spinning, consequently can obtain better curling effect.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a cross-sectional view of a micropore according to the present invention;
in the figure: 1-plate body, 2-circular groove, 3-first straight line groove and 4-second straight line groove.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1-2, the utility model relates to an asymmetric pass spinneret, include: the plate body 1 is provided with a plurality of spinneret orifices; each spinneret orifice comprises a guide hole and a micropore which are communicated with each other; the cross section of the micropore comprises a circular groove 2 positioned in the center of the micropore; the circular groove 2 extends outwards to form a first linear groove 3 and a second linear groove 4; the first linear groove 3 and the second linear groove 4 are perpendicular to each other;
in the scheme, the section of the fiber spun by the spinneret plate is in a combined shape of the first straight line groove, the second straight line groove and the circular groove, the combined shape is an asymmetric pattern, and due to the asymmetric appearance, asymmetric stress is generated during cooling shrinkage after the fiber is spun, so that a better curling effect can be obtained.
The utility model relates to an asymmetric pass spinneret, the fibre spinning cross-section of extruding in this scheme be circular and be connected first strip, second strip with circular, first strip, second strip mutually perpendicular, the combination of foretell figure is asymmetric figure, produces asymmetric stress when cooling shrink after the fibre spinning, consequently can obtain better curling effect.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
