The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated:
Consult Fig. 1 and Fig. 2; A preferred embodiment of the manufacturing approach of thin nonwoven layers thing of the present invention is the thin nonwoven layers thing that has flow-guiding structure in order to manufacturing; This manufacturing approach is to utilize a spunbond device for spinning 2 and to melt and spray device for spinning 3 simultaneously to carry out, and it comprises following steps:
Step 11: melt polymerization raw material.Consult Fig. 2; This step is simultaneously polymer raw material to be sent into spunbond device for spinning 2 and melted and sprayed in the hopper 21,31 of device for spinning 3; Utilize spunbond device for spinning 2 and the extruding screw 22,32 that melts and sprays device for spinning 3 to push and the high-temperature fusion operation respectively; After making polymer raw material form molten condition, pass through melt filtration and melt-stoichiometry again.
Step 12: the melt polymerization raw material is pumped into spinning fibre.Consult Fig. 2; Spunbond device for spinning 2 with melt and spray in the device for spinning 3 the melt polymerization raw material through filtration with metering after, then it is pumped into spinning fibre, polymer raw material can be for example polypropylene (PP), polyester (PET), nylon thermoplastic polymer raw materials such as (NYLON); Wherein, Melt polymerization raw material in spunbond device for spinning 2 is with the mode of a spinning unit 23 through the cooling drawing-off, and just pull becomes the continous mode long fiber under air-conditioning cooling wind action, promptly forms spunbond spinning fibre; And the melt polymerization raw material in melting and spraying device for spinning 3; Then be that just pull becomes fine fibre under the high-temperature gas effect with the mode of a spinning unit 33 through the hot blast drawing-off, promptly form and melt and spray spinning fibre.
Step 13: collect layer spinning fibre form in a molding 4 one have a flow-guiding structure thin-layer substance 5.In the present embodiment; Be to make spunbond spinning fibre on a molding 4, collect layer earlier to become the spun-bonded fibre stratum reticulare; Then make again melt and spray spinning fibre on the spun-bonded fibre stratum reticulare again collection layer become a meltblown fiber web layer, and the meltblown fiber web layer formation skim thing 5 that combines with the spun-bonded fibre stratum reticulare.
Simultaneously with reference to Fig. 3, Fig. 4; The employed shaping mould 4 of present embodiment comprises that one first shape layer 41 and that is the web plate form repeatedly places second shape layer 42 of first shape layer, 41 tops, and the shaping mould 4 of present embodiment is to be sheathed on cylinder 43 and rotation through cylinder 43 drives the form that displacement forms similar conveyer belt.
The inboard that shaping mould 4 is positioned at first shape layer 41 also is provided with a negative pressure unit 6, when spunbond spinning fibre with melt and spray spinning fibre and successively collect layer during in shaping mould 4 since the spunbond spinning fibre of this moment with melting and spraying that spinning fibre still has certain high temperature hardened forming fully as yet; Therefore; The negative pressure that cooperates negative pressure unit 6 to be provided can make spunbond spinning fibre and melt and spray spinning fibre to be easier to bonding formation thin-layer substance 5, in addition; Another effect that negative pressure unit 6 is set is; Because this moment, the spun-bonded fibre stratum reticulare and the meltblown fiber web layer of collection layer yet had certain pliability, so, through the suction-operated of negative pressure unit 6; Also be easier to make thin-layer substance 5 to rise and fall along with rib 421 structures of shaping mould 4 and form a plurality of fins 51 with by said fin 51 around the depressed area of defining out 52, be described flow-guiding structure.
What remark additionally is, because spunbond spinning fibre is successively to collect layer in shaping mould 4, therefore with melting and spraying spinning fibre; The spun-bonded fibre stratum reticulare of collection layer formation can be after molding the flow-guiding structure of corresponding concaveconvex structure earlier on the shaping mould 4 earlier; When the meltblown fiber web layer that the collection layer forms was incorporated into the spun-bonded fibre stratum reticulare, reshaping went out the flow-guiding structure of corresponding concaveconvex structure, in other words; When spun-bonded fibre stratum reticulare and meltblown fiber web layer are molded over 4 last times of shaping mould respectively, just mold flow-guiding structure respectively.Certainly, the spun-bonded fibre stratum reticulare of collection layer formation also can wait after the meltblown fiber web layer combination on it earlier, molds the flow-guiding structure of corresponding concaveconvex structure more together, does not exceed in proper order with this moulding.
Therefore, as stated, present embodiment be through make spunbond spinning fibre with melt and spray spinning fibre directly in order to the shaping mould 4 that molds flow-guiding structure the collection layer becomes net, make nonwoven fabric direct flow-guiding structure of the corresponding shaping mould of formation in the process that becomes net.Subsidiary one carry be, the fin 51 that is formed on the thin-layer substance 5 mainly is when thin-layer substance is used for amenities, can destroy the surface tension of fluid, make fluid can be broken to the littler globule and be easy to through the depressed area toward around diffusion mobile, reach the effect of water conservancy diversion.
Supplementary notes be that aforesaid shaping mould 4 is to make thin-layer substance 5 form fins, but in fact; When thin-layer substance 5 is adsorbed on 4 last times of shaping mould; Except forming fin 51, through the adsorption strength of adjustment negative pressure unit 6, the holes (figure does not show) that also can let thin-layer substance 5 formation can supply fluid to pass through.In addition; When spunbond spinning fibre with melt and spray spinning fibre and collect layer during in shaping mould 4; If its pliability is not enough so that it is obedient to shaping mould 4; Also can heat again it is softened collecting spun-bonded fibre stratum reticulare and the meltblown fiber web layer of layer on shaping mould 4, help it bonding and be obedient to shaping mould 4 through extra heater is set again.
Supplementary notes is again; The manufacturing approach of present embodiment is to utilize a spunbond device for spinning 2 and to melt and spray device for spinning 3 simultaneously to carry out; That is to say, the manufacturing approach of this nonwoven fabric be with spunbond-to melt and spray combination process (SM technology) be example, but in other variation aspect; Technology of the present invention also can be applied to SMS, SMMS combination process or technology spunbond separately, that melt and spray; Generally speaking, as long as make spinning fibre directly on shaping mould 4, become net, make it when becoming net, also mold flow-guiding structure and get final product in order to the moulding flow-guiding structure.
For example shown in Figure 5; When being applied to independent melt-blown process; Corresponding above-mentioned step 11 to step 13 is directly to utilize to melt and spray device for spinning 3 melt polymerization raw materials, then again with the polymer raw material of fusion through hot blast drawing-off be pumped into melt and spray spinning fibre after; Melt and spray spinning fibre collection layer straticulation thing 5 ' on shaping mould 8 again; And mold the fin 51 ' of the rib 81 of corresponding shaping mould 8 simultaneously, flow-guiding structure just, and shaping mould 8 also can be to be wound in a roller frame and the wire mesh cage structures that forms the cylinder shape.
Perhaps, consult Fig. 2 and Fig. 6, when being applied to independent spunbond technology; Be to melt and spray device for spinning 3 as what omit Fig. 2; Corresponding above-mentioned step 11 to step 13 is directly to utilize spunbond device for spinning 2 melt polymerization raw materials, then again with the polymer raw material of fusion after spunbond spinning fibre is pumped in the supercooling drawing-off; Spunbond spinning fibre is a collection layer straticulation thing 5 on shaping mould 9 again ", and mold the fin 51 of the rib 91 of corresponding shaping mould 9 simultaneously ".
Therefore, as stated, the present invention is incorporated in the moulding process of nonwoven fabric through the moulding with flow-guiding structure; Make spinning fibre when the collection layer becomes net; Just can mold flow-guiding structure, utilize the spinning fibre of being pumped into when the collection layer becomes net, still to be in hot mastication state to a certain degree, and simultaneously it is carried out the moulding of flow-guiding structure; Compared to way in the past; Can shorten the length of whole product line, and shorten the time-histories of the processed conveying of nonwoven fabric, so can reach the effect of saving operation and reducing cost really.
