Description
Technical field
The utility model belongs to spinning field, and in particular to a kind of profile spinneret of spinning.
Background technology
Terylene is weaving with a maximum kind of the yield controled the whole situation in chemical fibre, and its textile product is to function
Change, intelligent direction develops.Some can also provide various excellent functions, dacron by the new textile of special finishing
Windproof water repellent it is warming be exactly one of them.
Warming windproof water repellent is a kind of functional fabric, and fabric can not be impregnated under a certain pressure in wearing process reclaimed water
Inside, due to the tight structure of fabric, rainwater and wind cannot pass through fabric, so as to keep wearer pleasant, warm.Terylene it is anti-
Wind water repellent fabric mainly has three kinds of modes：Coated fabric, laminated fabric, tight type waterproof fabric.Wherein bind film and coating
Fabric there are problems that having discordant sound equipment when slightly hard feel, friction, should not dry-clean and.Tight type fabric is profit
The purpose of windproof water repellent is reached with change fabric construction, makes between fiber, is stacked between yarn closely, wind and rainwater are difficult leaching
Thoroughly.It is now to use tight type fabric more.Fiber is the non-conductor of heat, but the thermal conductivity ratio fiber of air is smaller, therefore
Air is good insulation medium, and air layer is thicker, and warming effect is better, therefore the doughnut with degree of hollowness has well
Warming effect.The high fabric of degree of hollowness can cause clothing light, and in especially moving out of doors, light clothing can mitigate people
Burden and expand its application.
Profiled filament can change the cross sectional shape of fiber so as to change in the structure of fabric, profiled filament spinning process,
There is recoverable elastic deformation in polymer melt, extrudate diameter is bigger than port mould diameter during flow, i.e., extrusion swelling is imitated
Should, extrusion swelling effect influences whether fiber degree of profile and conformal effect.Existing square hollow fiber setting due to spinneret orifice
Meter is unreasonable, and the extrusion swelling effect of melt causes squareness, degree of hollowness not high, and corresponding wind and water preventing effect can not embody
Come.
Utility model content
The purpose of this utility model is in view of the shortcomings of the prior art there is provided a kind of profile spinneret, by reasonable in design
Spinneret orifice shape and its arrangement can be used for producing the square hollow windproof hydrophobic polyester fibre in section there is provided a kind of
Spinneret, the hollow polyester fibre with rounded square tee section has been spinned by the spinneret, and is improved between polyester fiber
Tightness degree, the windproof water repellent fabric of high-performance is prepared for, while the fabric also has light-weighted advantage.
To achieve the above object, the utility model is adopted the following technical scheme that：
A kind of profile spinneret, the cross sectional shape of the profile spinneret spinneret orifice is square shape, and the square shape is
It is spaced and is formed by four shape identical quadrilateral holes；
The quadrilateral hole is slot or curl slot；
Arrangement mode between quadrilateral hole for the axis of each quadrilateral hole quadrilateral hole adjacent thereto axis
It is mutually perpendicular between line, another quadrilateral hole outside shorter side that the outer long side of each quadrilateral hole is adjacent thereto constitutes square shape
One side and each quadrilateral hole on the inside of short side on the inside of the corresponding two summits line in long side another quadrilateral hole adjacent thereto
The distance between corresponding two summit line is equal；
The axis direction of quadrilateral hole two summits line direction corresponding with the long side of quadrilateral hole is parallel.
The cross sectional shape of spinneret orifice has sphere of movements for the elephants type Ji " Swastika in the prior art " design of font spinneret orifice, sphere of movements for the elephants type
Spinneret orifice is bigger than the spinning pressure that narrow part is subject to compared with wide part, and spinning pressure is uneven suffered by melt, spinning pressure
Less part melt is easy to not squeeze, and square hollow fiber then deforms , " Swastika " font spinneret orifice design only one
After slit, melt extrusion, because fiber both sides squareness is inconsistent made from extrusion swelling effect, the wide side in side is narrow, it is difficult to
Ensure its squareness.The cross sectional shape of spinneret orifice, length and width when arranged distribution of the spinneret orifice on spinneret, are that influence is fine
Section squareness, degree of hollowness and the stable key factor of production are tieed up, the cross sectional shape of spinneret orifice of the present utility model is mouth word
Shape, it is ensured that section is rounded square hollow form after the fiber spinned is extruded through spinneret orifice；Suitable length-width ratio is used, is ensured
The degree of hollowness of fiber, it is ensured that the lightweight of fiber；Especially the present invention is spaced into mouth word from curl slot
Shape spinneret orifice, effectively overcomes polyester fiber due to the influence of extrusion swelling effect and surface tension, fibre section " fat big " shadow
Squareness and degree of hollowness are rung, the rounded square hollow form regularity in section is higher after the fiber spinned is extruded through spinneret orifice.
In summary, the utility model can spin out the hollow filament that section is positive square by above-mentioned spinneret, so that
So that filament stack tightness degree greatly improve, the windproof water repellent fabric of high-performance can be prepared, can meet cold, sleet, greatly
Dress in the bad weathers such as wind needs, and the light-weighted advantage of fabric has expanded the application of square fiber significantly.
It is used as preferred technical scheme：
Profile spinneret as described above, four sides of curl slot are all curl, and curl is curved for smooth single
Curve, the side of slot is straight flange.
Profile spinneret as described above, the length-width ratio of slot is 3-7:1；The long side of curl slot corresponding two
The ratio of distances constant of the distance of summit line two summit line corresponding with short side is 3-7:1.
On the inside of profile spinneret as described above, the long side in inner side of each slot another slot adjacent thereto
The short side ratio of distances constant of the distance between short side and slot is 0.2-0.5:1；Long side pair on the inside of each curl slot
On the inside of the two summit lines answered another curl slot adjacent thereto the distance between corresponding two summits line of short side it
Than for 0.2-0.5:1.
Profile spinneret as described above, the single buckling curve is parabola.
Profile spinneret as described above, arrangement mode of the spinneret orifice on spinneret is that spinneret orifice is flat in spinneret
According to concentric circles layered distribution on face.
As above polyester fiber made from any described profile spinneret spinning, the cross sectional shape of the polyester fiber is circle
Angle square hollow shape.
In polyester fiber as described above, rounded square hollow form polyester fiber the corresponding chord length of fillet with it is square corresponding
The ratio between length of side is 4-5:1, the fillet refers to the fillet in outside, the square corresponding length of side refer to it is square in be parallel to each other
