Summary of the invention
The present invention provides a kind of porous, thin dawn spinnerets, and its purpose mainly is to solve the spinnerets that uses in the prior art to cause same batch performances such as filament strength, elongation and dyeing inhomogeneous the problem of stability of spinning process difference.
For achieving the above object, the technical scheme that the present invention adopts is: a kind of porous, thin dawn spinnerets, comprise the spinnerets body, and be distributed with spinneret orifice on the spinnerets body, the hole count of said spinneret orifice is more than or equal to 192, and the aperture of spinneret orifice is less than 0.18 millimeter; State these spinneret orifices in arranged distribution on the spinnerets body on a plurality of concentric circles; Circle between each concentric circles is apart from equating, the pitch-row on each concentric circles between adjacent two spinneret orifices also equates; And said circle distance is greater than said pitch-row; The radius of said concentrically ringed inner ring is greater than said circle distance.
Related content in the technique scheme is explained as follows:
1, in the such scheme, the hole count of said spinneret orifice is 192～576.
2, in the such scheme, an end of said spinneret orifice is a charging aperture, and this charging aperture is a circular hole, and the other end of spinneret orifice is a discharging opening, and this discharge opening is that the cross section is the flat hole of " one " font, and the center of spinnerets body is pointed in this flat hole along its length.
3, in the such scheme, the hole wide region in said flat hole is 0.05～0.08mm, preferred Kong Kuanwei 0.06mm.
4, in the such scheme, the length and width ratio range in said flat hole is 8～12, and preferred length and width ratio is l0.
5, in the such scheme, said spinnerets body is circular.
6, in the such scheme, said circle is apart from referring in a plurality of concentric circles the radius difference between every two concentric circles that face mutually.
7, in the such scheme, said pitch-row refers to the distance between two the adjacent spinneret orifices on the same concentric circles.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
In the structure of the present invention, in the spinneret orifice arranged distribution on the spinnerets, when cooling air blows over; Though monofilament also has swing, owing to enclose distance greater than pitch-row, the monofilament of two adjacent rings can not intersect, bond together; And the penetrability of cooling air is better, makes cooling effect more even.In addition, because in the structure of the present invention, the concentrically ringed radius of inner ring is greater than the circle distance between each concentric circles; The wind direction of cooling air all points to the center of spinnerets; Form cooling air integrated air exhaust zone between spinnerets center and the inner ring concentric circles, make air draft smooth and easy, cool off more even.
