Abstract
The invention discloses a scattering fiber spinneret plate. The scattering fiber spinneret plate is characterized in that a spinneret plate body, spinneret holes and air needles are included, the air needles are located in the spinneret holes, the spinneret holes are arrayed in the spinneret plate body, spinneret hole inlets and spinneret hole outlets are respectively located in the upper side and the lower side of the spinneret plate body, and an air needle air inlet and an air needle air outlet are respectively located in the upper end and the lower end of each air needle. According to the scattering fiber spinneret plate, one air needle is further arranged in each spinneret hole so as to enable molten high polymer just extruded from each spinneret hole to be scattered by high-speed air currents. Consequently, fiber with stronger randomness can be formed, and formed fabric is more fluffy and softer. Meanwhile, due to the function of air currents, the molten high polymer extruded from the spinneret holes can be thinner.
Description
Technical field
The invention belongs to synthetic fiber spinning field, relate in particular to a kind of scattering fiber spinnerets.
Background technology
Spinnerets claims again spinning cap, and spinnerets can be transformed into the thread that has particular cross section shape by the high polymer molten of viscous state or solution by spinneret orifice, and process setting medium is as air or the curing strand that forms afterwards of coagulating bath.In spinneret orifice, install an air tube additional, utilize compressed-air actuated high velocity jet the molten high polymer spraying can be broken up to the fiber that formation is thinner in spinneret orifice, can manufacture the nonwoven material of more fluffy softness like this, utilize the method for air tube also not occur in current prior art, adopt the randomness of the fibre morphology structure that the method for air tube gas jet produces can be larger, can play purpose less than technique effect.
Summary of the invention
In order to overcome this problem, the invention provides a kind of scattering fiber spinnerets, can produce the scattering fiber that randomness is higher, the more fluffy softness of fabric of its composition.
Technical scheme of the present invention is to provide a kind of scattering fiber spinnerets, it is characterized in that: comprise spinnerets, spinneret orifice and air tube, it is inner that described air tube is positioned at described spinneret orifice, described spinneret orifice is arranged on described spinnerets, described spinneret orifice entrance and exit lays respectively at the upper and lower both sides of described spinnerets, and described air tube air inlet and gas outlet lay respectively at its upper and lower two ends.
As preferred version, described air tube gas outlet is conical, and described air tube gas outlet upper diameter is greater than described air tube gas outlet lower diameter.
As preferred version, described air tube is positioned at described spinneret orifice middle position.
As preferred version, described air tube is positioned at described spinneret orifice eccentric position.
As preferred version, place, described air tube gas outlet horizontal plane is higher than described spinneret orifice outlet place horizontal plane.
As preferred version, place, described air tube gas outlet horizontal plane is concordant with described spinneret orifice outlet place horizontal plane.
As preferred version, place, described air tube gas outlet horizontal plane is lower than described spinneret orifice outlet place horizontal plane.
Scattering fiber spinnerets of the present invention, in each spinneret orifice, set up an air tube, make just the molten high polymer of extruding in spinneret orifice be broken up by high velocity air, can form the fiber that randomness is stronger, the fabric of its composition is more fluffy and soft, due to the effect of air-flow, the molten high polymer that spinneret orifice is extruded can be more very thin simultaneously.
Accompanying drawing explanation
Fig. 1 is scattering fiber spinnerets tangent plane schematic diagram of the present invention;
Fig. 2 is the structural section figure of spinneret orifice and air tube on scattering fiber spinnerets of the present invention;
In figure: 1. spinnerets, 2. spinneret orifice, 3. air tube, 4. entrance, 5. outlet, 6. air inlet, 7. gas outlet.
The specific embodiment
Below the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, 2, a kind of scattering fiber spinnerets of the present invention, it is characterized in that: comprise spinnerets 1, spinneret orifice 2 and air tube 3, air tube 3 is positioned at described spinneret orifice 2 inside, spinneret orifice 2 is arranged on spinnerets 1, and spinneret orifice entrance 4 lays respectively at spinnerets with outlet 5, and Shang Xia 1 both sides, and air tube air inlet 6 and gas outlet 7 lay respectively at its upper and lower two ends, air tube gas outlet 7 is conical, and air tube gas outlet 7 upper diameter are greater than air tube gas outlet 7 lower diameter.
The gas outlet 7 of air tube is designed to conical structure, and air tube 3 radial dimensions that gas is flowed through before ejection are more and more less, when gas sprays from tip suddenly, has more burst, and the unexpected scattering of air-flow is come, and molten high polymer is broken up to formation scattering fiber.
Same spinnerets 1 is provided with several with the spinneret orifice 2 of air tube 3, can extrude the scattering fiber of corresponding radical simultaneously.
As a kind of embodiment of the present invention, air tube 3 is positioned at spinneret orifice 2 middle positions, and 7 horizontal plane positions, place, air tube gas outlet export 5 horizontal plane positions, place with respect to spinneret orifice can be adjusted to three kinds of situations: 1) air tube gas outlet 7 place horizontal planes export 5 place horizontal planes higher than spinneret orifice; 2) to export 5 place horizontal planes concordant for air tube gas outlet 7 place horizontal planes and spinneret orifice; 3) air tube gas outlet 7 place horizontal planes export 5 place horizontal planes lower than spinneret orifice.
As a kind of embodiment of the present invention, air tube 3 is positioned at spinneret orifice 2 eccentric positions, and 7 horizontal plane positions, place, air tube gas outlet export 5 horizontal plane positions, place with respect to spinneret orifice can be adjusted to three kinds of situations: 1) air tube gas outlet 7 place horizontal planes export 5 place horizontal planes higher than spinneret orifice; 2) to export 5 place horizontal planes concordant for air tube gas outlet 7 place horizontal planes and spinneret orifice; 3) air tube gas outlet 7 place horizontal planes export 5 place horizontal planes lower than spinneret orifice.
The explanation of a same embodiment, just air tube 3 is positioned at spinneret orifice 2 eccentric positions, the power that the molten high polymer being extruded in spinneret orifice 2 is sprayed by gas in each direction with respect to air tube 3 is inhomogeneous, and the molten high polymer in same spinneret orifice 2 is dispersed into the scattering fiber of thickness inequality simultaneously.
The scattering fiber that the present invention can produce has higher fiber number, the fabric that scattering fiber forms, the more fluffy softness of supatex fabric feel particularly, the randomness that supatex fabric needs also fully demonstrates in jet-impingement process, and the structure of fiber is more random.
Above embodiment is only the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
