Abstract
The utility model relates to a spinneret for moistured and ventilated long fibers, in particular to a spinneret for producing moistured and ventilated long fibers, wherein, the spinneret holes of the spinneret are crosswise distributed and consist of a lead hole and a spinneret pore, the section shape of the spinneret pore is cross-shaped; the left and the right sections of the cross shape are trapezia-shaped; the upper section and the lower section are two millipores which are large hemicycle-shaped; the upper bottom of the trapezia of the left section and the right section are stuck into a whole horizontally, the upside and the downside of the sticking point at the upper bottom of the trapezia of the left section and the right section are respectively stuck with one of the millipores which are of large hemicycle-shaped. With the spinneret, the moistured and ventilated long fibers produced are of good moistured and ventilated effects and good orderliness of fiber threads.
Description
Relate to the field:
The utility model relates to the long stapled spinnerets of a kind of spinning moistured and ventilated, is in particular a kind of spinning moistured and ventilated filament fiber spinnerets that is used for producing.
Background technology:
In the prior art, the doughnut speed of production of producing with conventional spinning method is low, and the scope of application is restricted, and general road, the work back DT silk that is fit to is produced, and tubular filament is of poor quality, and production efficiency is lower, and production cost is higher.
Summary of the invention:
The purpose of this utility model is to provide and adopts High-speed Spinning Production technology to spin moistured and ventilated filament fiber spinnerets.
The purpose of this utility model can realize by following technical solution:
A kind of spinning moistured and ventilated filament fiber spinnerets, spinneret orifice on the spinnerets can distribute in the form of a ring, also but diamond shape distributes or other distribution forms in addition, spinneret orifice is made up of guide hole and spray silk pore, the cross sectional shape of described spray silk pore is cross shape, two sections is trapezoidal about its cross shape, two sections are the micropore of two large semicircle shapes, about two sections trapezoidal upper base levels be bonded as one, be bonded as one with the micropore of a large semicircle shape up and down with respectively two sections horizontal bonding places of trapezoidal upper base.
The purpose of this utility model can further realize by following technical measures:
Aforesaid a kind of spinning moistured and ventilated filament fiber spinnerets, the trapezoidal slit in cross section of the wherein said spray silk pore wide B that partly goes to the bottom is 0.18-0.22mm, upper base width b is 0.09-0.13mm, circular portion diameter D1 is 0.15-0.25mm, and the pore total length is that L is 1.05-1.16mm; Overall width H is 0.48-0.54mm.
Aforesaid a kind of spinning moistured and ventilated filament fiber spinnerets, wherein said guide hole diameter is 0.28-0.40mm, spray silk pore height h is 0.4-0.9mm.
The utility model is compared with existing long filament production technology, spinneret orifice is made up of the guide hole and approximate cross micropore two parts of circle, the effect of guide hole is to enter micropore with guiding the melt continuously smooth, the high polymer molten that is viscous state is by behind the micropore, because the elasticity of high polymer molten, from the melt thread that micropore is extruded, processes such as drawn, cooling, curing become the fiber with moisture transported permeable performance, form the POY spinning cake or become the FDY spinning cake after drawing-off through reeling.Use the spinnerets of this shape pass to have that melt flowability is good, the expanded phenomenon of spinneret orifice exit melt normal, melt is difficult for breaking, the fiber of producing has advantages such as moisture transported permeable.Because special-shaped fibre section, make fiber have fine moisture absorption hydrofuge performance, made fabric not only can sop up the sweat that human body surface is discharged, and the moisture of being inhaled in the lining can also be discharged in the short period of time, have good wicking, shorten greatly lining moisture absorption, lead wet and the hydrofuge process.Under same condition, the moisture absorption of this fiber, lead wet rate apparently higher than fibers such as cotton, nylon, acrylic fibers, be particularly suitable for doing sportswear, military uniform etc., also be fit to making geotextiles etc.
Description of drawings:
Fig. 1 is the structural representation of a preferred embodiment of the utility model.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Fig. 3 is that the B of Fig. 2 is to structural representation.
The specific embodiment:
Shown in Fig. 1-4, the spinneret orifice 2 on the utility model spinnerets 1 distributes in the form of a ring, but in addition also diamond shape distribute or other distribution forms.The number of turns that spinneret orifice is arranged can be set according to the quantity of spinneret orifice, the requirement of production kind dpf number.Spinneret orifice 2 is made up of guide hole 3 and spray silk pore 4, the cross sectional shape of spray silk pore 4 is cross shape, two sections is trapezoidal about its cross shape, two sections are the micropore of two large semicircle shapes, about two sections trapezoidal upper base levels be bonded as one, be bonded as one with the micropore of a large semicircle shape up and down with respectively two sections horizontal bonding places of trapezoidal upper base.The trapezoidal slit in cross section of the spray silk pore width B of partly going to the bottom is 0.18-0.22mm, and upper base width b is 0.09-0.13mm, and circular portion diameter D1 is 0.15-0.25mm, and the pore total length is L=1.05-1.16mm; Overall width H=0.48-0.54mm.Guide hole diameter D is 0.28-0.40mm,, spray silk pore height h is 0.4-0.9mm.Adopt high-speed spinning long filament production Technology, the POY winding speed is 2500-3600m/min.Winding speed is 3600-4900m/min when producing FDY.
Moisture transported permeable doughnut spinnerets 1 of the present utility model is a core apparatus of producing the penetrable ventilated tubular filament assembly of polyester derivative, this spinnerets 1 is made by metal material, be provided with spinneret orifice 2 on it equably, this spinneret orifice 2 is vertical with 1 of spinnerets, this spinneret orifice 2 is made up of the guide hole 3 and spray silk pore 4 two parts of circle, and this guide hole mouth and this spray silk pore aperture are divided into the side, two ends of spray plate body.The length direction of approximate cross spinneret orifice is along spinnerets circular arc direction.Adopt this kind spinnerets, advantage such as it is good that the moistured and ventilated long fiber of production has the moisture transported permeable performance, and the regular shape property of strand is good.After making fabric, dress is nice and cool, moisture transported permeable, and very Chinese juniper shape is good, comfortable and easy to wear.
