23。
As shown in fig. 6, bonding trail 220 in adhesive section 22 is located at two spinneret channels, 2 inside, by bonding trail 2
Hot-melt polymer in two spinneret channels 2 is bonded in advance, is had between the parallel composite fiber made relatively strong
Adhesion strength, effectively interface is avoided to remove.
As shown in Figures 3 to 5,2 side wall of spinneret channel in diversion section 21 is equipped with water conservancy diversion trail 210, water conservancy diversion trail 210
Side along squeeze out direction gradually to other side spinneret channel 2 extend.Purpose is so that the hot melt in water conservancy diversion trail 210 polymerize
Object can slowly flow and be filled up completely water conservancy diversion trail 210, and allow hot-melt polymer gradually to opposite spinneret
Channel 2 is close, and 210 section of water conservancy diversion trail is more slowly, to generate when can avoid close dead with the deformation velocity for squeezing out direction
Area.
Secondly, 210 section of water conservancy diversion trail is round or oval, the hot melt entered in the water conservancy diversion trail 210 can be made
Polymer flow rate maximizes, and can be sufficient filling with water conservancy diversion trail 210 and bonding trail 220, avoid dead zone.
As shown in Figure 4 and Figure 5, it is staggered between the water conservancy diversion trail 210 on two spinneret channels 2, passes through water conservancy diversion trail
Hot-melt polymer in 210 pairs of respective spinneret channels 2 is dredged, so that two finally flowed out from spinneret orifice 23 polymer
Fiber filament 3 is rendered as the structure in Fig. 7, and the binding part 30 between fiber filament 3 passes through the guidance of water conservancy diversion trail 210 to bonding trail
220 form, and the filametntary binding part 30 of two kinds of polymer is intersecting state, in addition to left and right is the same as the bonding of filament
Outside, there are also the face contact between the binding part 30 under laminated arrangement, adhesion strength is greatly improved, interface is avoided to remove.
Since water conservancy diversion trail 210 mainly guides the flow direction of hot-melt polymer, and bond trail 220 and spray
Wire hole 23 is to need to bond the binding part 30 in fiber filament, therefore the axis between diversion section 21 and two spinneret channels 2
The angle of heart line is greater than the angle between adhesive section 22 and axial line, since the section in water conservancy diversion trail 210 in diversion section 21 is bigger,
Therefore it is bigger to can permit the inclination of diversion section 21；But it is adhered state since the binding part 30 of fiber filament 3 in adhesive section 22 is in,
It needs for binding part 30 at two to be slowly pressed against, therefore bonding trail 220 in adhesive section 22 and spinneret channel 2 are slowly to lean on
Close, the inclined degree opposite flow section 21 of adhesive section 22 is smaller.
The initial cross-section area in water conservancy diversion trail 210 is greater than bonding 220 area of section of trail, the polymerization in water conservancy diversion trail 210
Logistics speed can be higher, and the polymer of receiving is also just more, so that a large amount of hot-melt polymer is entered by water conservancy diversion trail 210
It bonds in trail 220, guarantees that in bonding trail 220 be not in dead zone, gap is avoided to generate.
Along section conversion of the direction gradually to bonding trail 220 is squeezed out, water conservancy diversion trail 210 is flowed in the section in water conservancy diversion trail 210
The flow velocity for entering to bond the polymer in trail 220 is slowly varying process, and unexpected change in ladder shape is not present, and avoids flow velocity prominent
Raw gap or bubble are sold of one's property, dead zone is avoided the formation of.
If Fig. 3 is into Fig. 5, when moving in water conservancy diversion trail 210, the filametntary binding part 30 in side is gradually to other side fibre
Silk movement is tieed up, and forms the shape of intersecting in moving process.
When binding part 30 enters bonding trail 220 by water conservancy diversion trail 210, the filametntary binding part 30 in side start with
Fiber filament connection in the other side bonds, and still there are certain gaps between binding part 30 adjacent at this time.
Binding part 30 is pressed by spinneret orifice 23 to middle part after as shown in figure 8, completes the bonding of middle part binding part 30.
The section of spinneret orifice is " Lv " shape in this implementation, and the composite fibre finally come out is in " Lv " shape structure, for liquid
Body fluid has stronger guiding role, so that liquid is more faster in composite fiber surface flowing, assigns the compound fibre
Tie up higher wet guilding.
Embodiment 2:
As shown in figure 9, since the flow cavity in the filter chamber 6 in the spinning appts in embodiment 1 needs to carry out bubble
It excludes, therefore its placement angle is very limited, it is necessary to vertical display, therefore spinning appts bottom needs a large amount of space
For being collected to composite fibre silk.
Therefore for expansion space, as shown in figure 11, spinneret 8 is turned down 90 degree in the present embodiment, so that spinneret 8
Outlet is towards level, and the location of filter chamber 6 is constant.
Therefore fiber filament comes out direction towards side, can utilize to horizontal space, greatly expands needed for operation
Space.
The above is a preferred embodiment of the present invention, does not depart from this hair for those of ordinary skill in the art
Under the premise of bright principle, several variations and modifications can also be made, these also should be regarded as protection scope of the present invention.
