Abstract
The utility model relates to spinneret plate orifices for three-blade hollow composite fibers, wherein the spinneret plate orifices for the three-blade hollow composite fibers can be used for spinning the composite fibers. Each spinneret orifice is of a symmetrical three-blade profile structure formed by a V-shaped slit unit with a 120-degree opening and a linear slit unit, wherein the adjacent parts at the bottoms of the V-shaped slit unit and the linear slit unit are respectively an inwards-concave arc, not communicated with each other and spaced by a certain distance. The spinneret plate orifices of the three-blade hollow composite fibers are high in structure precision, the cross sections of the spun fibers are in the three-blade hollow type, the spinneret plate orifices can be applied to a twin-screw extrusion device, the spun composite fibers are of the three-blade hollow structure, and thus the requirement for production of multifunctional fibers is met.
Description
Technical field
The utility model relates to a kind of spinning spinneret plate structure, particularly a kind of spinneret hole structure for the production of three leaf hollow type composite fibres.
Background technology
That Profiled hollow fiber has is fluffy, warming, moisture absorbing and sweat releasing, the plurality of advantages such as soft, the composite fibre with special-shaped hollow structure, according to the selection collocation of matrix component, also can there is more functional characteristics, as elasticity, electric conductivity etc., thereby have great importance in the exploitation of new textile.For satisfying the demands, the utility model has designed a kind of features simple structure, and the spinneret hole structure that precision is high can be used for producing three leaf hollow type composite fibres.
Summary of the invention
The purpose of this utility model is to provide a kind of spinneret hole structure of producing three leaf hollow type composite fibres, coordinate corresponding spinning equipment and assembly, can manufacture order component or three leaf hollow type fibers of two components, spinneret pore structure is easy, precision is high, good spinnability, institute's producd fibers can be designed abundant multifunctionality.
The designed spinneret hole structure of the utility model adopts following preferred technical scheme:
Each spinneret orifice forms symmetrical trilobal cross contour structure by " V " shape slit unit and " one " font slit unit of 120 ° of openings.The bottom adjacent part of " V " shape and " one " font slit unit is the circular arc of indent, and the two is not connected.
Each blade length and width of the formed trilobal cross structure of spinneret orifice is identical, and between adjacent blades, angle is 120 °.
Wherein, the length a of each blade of trilobal cross structure is 0.1～0.8mm, and slit width b is 0.05～0.4mm, and length-width ratio a/b is 1～4.
Beeline c between " V " shape of each spinneret orifice and " one " font slit unit is 0.02～0.1mm.
The beneficial effects of the utility model:
The utility model spinneret pore structure is simple and easy, guarantees the good spinnability of precision height and fiber; The split-type structural that spinneret orifice is comprised of two slit unit, can be used for producing bi-component composite fiber; The design of middle circular cavity can flexible modulation, makes fiber reach desirable degree of hollowness.Therefore, use the spinnerets of this structural design to spin three leaf hollow type fibers, there is abundant multifunctionality.
Accompanying drawing explanation
Fig. 1 the utility model spinneret hole structural representation
The specific embodiment
The utility model is described in further detail by reference to the accompanying drawings.
Embodiment
As the structural representation that Fig. 1 is spinneret hole, spinneret orifice forms symmetrical trilobal cross contour structure by " V " shape slit unit and " one " font slit unit of 120 ° of openings.The bottom adjacent part of " V " shape and " one " font slit unit is the circular arc of indent, and the two is not connected.
Each length of blade a of the formed trilobal cross structure of spinneret orifice is 0.5mm, and slit width b is 0.2mm, and length-width ratio a/b is 2.5; Between adjacent blades, angle is 120 °; Beeline c between " V " shape of spinneret orifice and " one " font slit unit is 0.05mm.
The spinnerets being designed by said structure spinneret orifice, can be used for manufacture order component or bi-component composite fiber, and fibre section structure is three leaf hollow types.
Above are only illustrating of the utility model possible embodiments, not technical scope of the present utility model is imposed any restrictions, allly do not depart from any trickle modification, equivalent variations and the retouching that the utility model is done, still belong in technical scope of the present utility model.
