The specific embodiment
See Fig. 1-11, the nonwoven production of present embodiment comprises with rectangle composite spinneret assembly and stacking up and down successively: feedboard 1, flow guide distribution plate 2, compound distribution plate 3 and spinnerets 4.
Said feedboard 1 is provided with first, second group melt charging hole 11,12 that is used for importing respectively first, second component raw material, and is distributed in the pilot hole 13 that is used to connect flow guide distribution plate 2, compound distribution plate 3 and spinnerets 4 around the feedboard 1.
Said flow guide distribution plate 2 is provided with respectively first, second guiding gutter group 21,22 relative with said first, second group melt charging hole 11,12, is distributed with first, second pod apertures 25,23 in first, second guiding gutter group 21,22 respectively.Said first group of melt charging hole 11 on the said flow guide distribution plate 2 is located at the central portion of flow guide distribution plate 2, and said second group of melt charging hole 11,12 is provided with around first group of melt charging hole 11.On the bottom surface of said flow guide distribution plate 2, the exit of said first pod apertures 25 is provided with conical tank 24.
Said compound distribution plate 3 is provided with respectively first, second composite flow guide hole 33,31 relative with said first, second pod apertures 25,23; The bottom face in the first composite flow guide hole 33 is provided with discharging boss 34, and the bottom surface of this discharging boss 34 is provided with " rice " word guiding gutter 36, should be evenly distributed with 8 pores 35 that communicate with the said first composite flow guide hole 33 by " rice " word guiding gutter interior 36.The port in said first, second composite flow guide hole 33,31 on the said compound distribution plate 3 is distributed in respectively in first, second guiding gutter 34,32; Second guiding gutter 32 is says font; First guiding gutter 34 is a pair of rectangular channel, and this is located at the said a pair of rectangular portion of saying second guiding gutter 32 of font respectively to rectangular channel.
Said spinnerets 4 be provided with respectively with the said first composite flow guide hole 33 on the spinneret orifice 41 that is oppositely arranged of discharging boss 34.Be provided with Compound Cavity between compound distribution plate 3 and the spinnerets 4.
The course of work when carrying out composite spinning: the raw material of two kinds of heterogeneitys, different melting points flows into two groups of melt charging holes of feedboard 1 respectively under force, two kinds of raw materials are injected under force in the corresponding flow guide distribution groove group on the flow guide distribution plate 2.Different raw materials each pod apertures on bottom land in corresponding flow guide distribution groove group flows in each the composite flow guide hole on the compound distribution plate 3, and flow guide distribution plate 2 goes out that the position in composite flow guide hole is corresponding accordingly on pod apertures and the compound distribution plate 3 on the charge level.
Raw material can advance in the Compound Cavity through pod apertures and composite flow guide orifice flow under the promotion of ambient pressure; Because each the discharging boss 34 on the bottom face 34 of compound distribution plate 3 is corresponding with each spinnerets guide hole 41 on the spinnerets 4; The A raw material can directly flow to spinnerets guide hole 41 by pressure through A raw material pod apertures like this; And the B raw material is through " rice " word guiding gutter entering spinnerets guide hole 41 of discharging boss; Two kinds of raw materials get into a duct at synchronization by different paths, so just formed composite spinning.
