Brief description
Fig. 1 is the structural representation of spinneret in one embodiment of this utility model.
Fig. 2 is the structural representation of the spinneret orifice on spinneret in Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in detail.
Fig. 1 is the structural representation of spinneret in one embodiment of this utility model.As shown in figure 1, using in the present embodiment
In produce doughnut spinneret be circle, on spinneret rule arrange multiple spinneret orifices 1.
Spinneret orifice 1 is on spinneret plane according to concentric circular layered distribution.Spinneret orifice 1 on each layer of concentric circular is circumferentially
Equidistantly distribute.Spinneret orifice 1 between layers is staggered.
Fig. 2 is the structural representation of the spinneret orifice on spinneret in Fig. 1.As shown in Fig. 2 each spinneret orifice 1 is by three
Umbrella shape groove is constituted, and wherein each umbrella shape groove includes the umbrella cover groove 11 of a circular arc and a umbrella handle groove being connected in the middle of umbrella cover
12.
Wherein umbrella cover groove 11 is an arc groove, and the umbrella cover groove 11 of three umbrella shape grooves is located at the same circle with spinneret orifice as the center of circle
Zhou Shang, is provided with gap between two neighboring umbrella cover groove 11.
The configuration of spinneret orifice 1 is crowded around according to 120 ° of angles by three umbrella shape grooves and is formed, the umbrella handle groove of three umbrella shape grooves
12 are connected in the circle centre position of spinneret orifice 1, each umbrella handle groove 12 point to the geometry center of circle of spinneret orifice 1, umbrella cover groove 11 circular arc to
Dissipate outward, form mode of appearance as vehicle steering for the shape.
Each spinneret orifice 1 described all has a umbrella handle groove 12 to point to the radial direction of spinneret 1 circle.
Shape convenience and spinning process melt cooling effect etc. in view of spinneret require, and internal layer " bifurcation " word supports
Center of arc is connected with outer layer, is spaced certain interval between three circular arcs of outer layer, is beneficial to inner skeleton part melt flow and spins
The timely and effective cooling of silk process.The spacing of outer layer circular arc gap location needs careful design, and spinning melt is from filament spinning component
Spinneret orifice in injection flow out when, one side spinning melt outer layer doughnut portions can expanded adhesion make circular arc closure, another
The outer layer spinning melt of aspect circular arc under the influence of cross air blasting can take the lead in cooling down knot compared with internal layer " bifurcation " word support frame part
Brilliant.If the spacing of peripheral gap is too small, peripheral melt is expanded be closed into sealing annular when, internal " bifurcation " word support frame
The still insufficient cooling crystallization of part spinning melt, the melt macromolecular chain structure being easily caused inside " bifurcation " character skeleton part is unstable
Fixed, under smelt surface tension effect, interior " bifurcation " word support section occurs convergence to inside contract makes three cavitys of doughnut occur
Gross distortion even closes disappearance, destroys the morphosiss of whole fiber；If spacing is excessive, peripheral spinning melt is expanded limited
Or premature solidification convergence, it is impossible to form the annular of complete closure, may be deformed into the SANYE Fructus Citri tangerinae lobed that three trianglees are piled up
Section, its degree of hollowness and warmth retention property will be had a greatly reduced quality.
In this utility model, spray webbing pore morphology main structure parameters have: length h of umbrella handle groove 12, the thickness of umbrella handle groove 12
The bifurcation font that gap c between a, the thickness b of umbrella cover groove 11, the width m of umbrella cover groove 11, umbrella cover groove 11 and three umbrellas are formed after crowding around
Inner support hollow circle name outside diameter d etc..Wherein, umbrella handle groove 12 length h and umbrella cover groove 11 width m all with spinneret orifice nominal diameter d
Associated, wherein, h=d/2-b, m=2 π d/3-c.Therefore, spinneret orifice name outside diameter d is bigger, then umbrella handle groove 12 length h and umbrella
Width m is also bigger for face groove 11.And spinneret orifice name outside diameter d depends on being spun into the single fiber diameter of silk, and it is subject to spinning melt viscosity flow
Property and spinning process drafting multiple impact, therefore first have to determine intend development specification, i.e. synnema fiber number, ultimate fibre fineness
With f number.And gap c between umbrella handle groove 12 thickness a, umbrella cover groove 11 thickness b and umbrella cover groove 11 etc. is then to determine to be spun into a single fiber
Can the key parameter of dimension cross section structure, and by the multifactor impact such as spinning melt viscosity flow, cooldown rate and drafting multiple, to
Spin more satisfactory fiber design section morphology most important.
When a, b, c, d all than larger when, fibre forming is bad, when spinning speed is high, wind speed is low, goes out spinneret orifice melt stream
Cooling is slow, and stretching convergence seriously leads to ultimate fibre arc outer layer can not close and lumen sky cracking phenomena；Spinning speed mistake
When low, wind speed is too high, go out the expanded rear quick cooling of spinneret orifice melt stream, stretching restrains generation at umbrella handle, although ultimate fibre
Arc outer layer closure is good, but umbrella handle is short and thick, leads to ultimate fibre lumen to diminish, and section assumes " three buttons " form.And work as
When a, b, c, d reduce simultaneously, fibre forming is also undesirable, shows as that ultimate fibre arc outer layer closure is good and lumen becomes triangle
Sharpen, degree of hollowness substantially reduces.
After optimization design, the gap c length between two neighboring umbrella cover groove 11 is 0.08-0.15mm, the length of umbrella handle groove 12
Degree h is 0.3-0.6mm, and the thickness a of umbrella handle groove 12 is 0.05-0.15mm, and the thickness b of umbrella cover groove 12 is 0.1-0.3mm, umbrella cover groove
12 width m is 1.0-1.5mm, and the nominal outside diameter d of spinneret orifice 1 is 1.1-1.55mm.
In preferred embodiment, d=1.25mm, a=0.1mm, b=0.125mm, c=0.1mm, m=1.2mm.
Although this utility model is disclosed as above with preferred embodiment, this utility model is not limited to this.Any
Skilled person, without departing from spirit and scope of the present utility model, all can make various changes or modifications, therefore this practicality
New protection domain should be defined by claim limited range.
