Abstract
The utility model discloses a filature spinneret, which comprises a spinneret plate, wherein, the spinneret plate is provided with a first group of separating spinneret orifices and a second group of separating spinneret orifices, wherein, the axial lead of the first group of separating spinneret orifices is intersected with the axial lead of the second group of the separating spinneret orifices outside the spinneret plate. The spinneret has simple structure, and is suitable for producing different paralleling composite fibers; the produced paralleling composite fibers have clear marginal and curving property.
Description
Technical field
The utility model relates to the spinning equipment of making composite fibre, particularly relates to a kind of spinning nozzle of producing parallel composite fiber.
Background technology
Filament spinning component is a key equipment of producing composite fibre, has determined elasticity, crimpiness, dyeability and other performances whether good of composite fibre.Original parallel composite fiber all is to produce with traditional composite spining module.Adopt the composite spinning technology of traditional filament spinning component to be, before entering spinneret orifice, two kinds of compositions are separated from one another, do not mix mutually, in the moment that enters spinneret orifice, two kinds of liquid contacts, solidify and be bonded into a rhizoid bar, thereby form composite fibre with two or more different component.This composite fiber spinning assembly generally comprise the distribution plate that makes two kinds of different compositions interflow and being used for of combining with distribution plate will two kinds of polymer diameter reduction at interflow after from spinning the spinneret plate of weaving out in the hole, complex structure, manufacturing cost height, technique controlling difficulty is big, and fiber two components are diffusion mutually easily on the interface, influences every performance of composite fibre; In addition, most of spinneret orifices are designed to circle, and the cross sectional shape of the composite fibre of producing also is circular, does not have different crimp property.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of spinning nozzle is provided, this spinning nozzle is simple in structure, is suitable for producing various parallel composite fibers, and the boundary of the parallel composite fiber of producing clear, have a different crimp property.
For solving above technical problem, the utility model is taked following technical scheme:
A kind of spinning nozzle comprises spinnerets, offers the first component spinneret orifice and the second component spinneret orifice on the described spinnerets, and intersect in the place of axial line outside spinnerets of the axial line of the first component spinneret orifice and the second component spinneret orifice.
Described first spinneret orifice has first entrance that is positioned at described spinnerets upper surface and first ejiction opening that is positioned at the spinnerets lower surface, second spinneret orifice has second entrance that is positioned at the spinnerets upper surface and second ejiction opening that is positioned at the spinnerets lower surface, the diameter of first entrance is greater than the diameter of first ejiction opening, and the diameter of second entrance is greater than the diameter of second ejiction opening.
Distance between described first ejiction opening, second ejiction opening is for being preferably 0.1～0.5 millimeter.
More preferably 0.15～0.3 millimeter of distance between described first ejiction opening, second ejiction opening.
Angle between the axial line of the axial line of described first ejiction opening and second ejiction opening is preferably 0～90 degree, and further is preferably 45～90 degree.
The above-mentioned first spray component spinneret orifice, the second component spinneret orifice are circular port.On spinnerets, can offer a plurality of first above-mentioned spinneret orifices and second spinneret orifice.
Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:
Spinning nozzle has two row spinneret orifices, and the axle center opposite tilt of this two row spinneret orifice, the place of position outside spinnerets that intersect in the axle center, two kinds of components making composite fibre are flowed out in two close spinneret orifices, two rhizoids are bonded as one after going out spinnerets, because two components all are independently more than the outlet of composite spinneret, the bounding point of component is below spinnerets, use it for when producing composite fibre, polymer viscosity and spinning temperature can (kneeing) not impact parallel composite fiber " canting ", technique controlling difficulty is little, the boundary of the parallel composite fiber of producing is clear, when having the premium properties of composite fibre, two components of forming composite fibre can fully keep separately feature performance benefit (as curling naturally that the crimp property difference causes, the contrast effect that the dye-uptake difference causes etc.).
Description of drawings
Fig. 1 is a longitudinal section of the present utility model schematic diagram;
Wherein:
1, spinnerets; 10, the first component spinneret orifice; 11, the second component spinneret orifice; 100, first entrance; 101, first ejiction opening; 110, second entrance; 111, second ejiction opening.
The specific embodiment
The utility model is described in more detail below in conjunction with accompanying drawing and concrete embodiment:
As shown in Figure 1, offer the first component spinneret orifice 10 and the second component spinneret orifice 11 of opposite tilt on the spinnerets 1 according to the spinning nozzle of present embodiment.
The first component spinneret orifice 10 narrows down in the position contraction near spinnerets 1 lower surface, and the diameter of first entrance 100 is greater than the diameter of first ejiction opening 101; The second component spinneret orifice 11 also shrinks in the position of close spinnerets 1 lower surface and narrows down, and the diameter of second entrance 110 is greater than the diameter of second ejiction opening 111.
First ejiction opening 101 and second ejiction opening 111 all are positioned on its lower surface.For the every performance that guarantees spun compound silk all reaches best, the distance c between first ejiction opening 101 and second ejiction opening 111 is designed to 0.15～0.3 millimeter, and the angle α between first ejiction opening 101, second ejiction opening 111 is designed to 45～90 degree.
In the present embodiment, the first component spinneret orifice 10 and the second component spinneret orifice 11 are circular.
To sum up, two kinds of components making composite fibre are flowed out in two close spinneret orifices, two rhizoids are bonded as one after going out spinnerets, because two components all are independently more than the outlet of composite spinneret, the bounding point of component is below spinnerets, use it for when producing composite fibre, polymer viscosity and spinning temperature can not impact parallel composite fiber " canting ", technique controlling difficulty is little, the boundary of the parallel composite fiber of producing is clear, when having the premium properties of composite fibre, two components of forming composite fibre can fully keep separately feature performance benefit (as curling naturally that the crimp property difference causes, the contrast effect that the dye-uptake difference causes etc.), thus final body reveals unexistent special shape of general composite fibre and performance.
