Abstract
The invention relates to a method and to a device for treating a fiber mass (21), for example a nonwoven or a woven. Such fiber masses are guided through a pressing stand (22) for treatment in which they are pressed in at least one pressing zone (53) by means of a press roller (51), thereby pressing out from the fiber mass (21) a treatment fluid already present in the fiber mass (21). Once the treatment fluid is pressed out, a second treatment fluid is introduced into the fiber mass (21). In order to achieve as rapid and homogeneous a distribution of the second treatment fluid in the pressed-out fiber mass (21) as possible, the treatment fluid is introduced in an expansion zone (55) in which the pressure exerted by the press roller (51) decreases in the direction of movement (B) of the fiber mass (21) through the press roll surface (59), the press roll surface (59) being the surface by which the pressure acts onto the fiber mass (21).
Description
Technical field
The present invention relates to a kind of method of handling fibrous material such as fabric or bondedfibre fabric, wherein, fibrous material transmits by extruder, fibrous material extrudes by the extruding force that acts on the fibrous material in the compressive surface of at least one crush zone by at least one pressure roller in extruder, and the fibrous material that is forced out floods with treatment fluid, fibrous material transmits by a breathing space in crush zone, and extruding force reduces by direction along fibrous material in the breathing space.
The invention still further relates to the press-roller device of a kind of processing with respect to the fibrous material of press-roller device motion, comprise a pressure roller, pressure roller has compressive surface, when working, produce an extruding force that acts on the fibrous material by it at crush zone, and an immersion system is arranged, when working, a kind of treatment fluid is infeeded fibrous material by it, wherein, crush zone constitutes a breathing space when work, and extruding force reduces along the direction of motion of fibrous material in this breathing space.
Background technology
Compressive surface is meant this surface, and it just refers to a kind of so Utopian enveloping surface as the boundary of the surface imagination or in esse formation fibrous material upside or downside crush zone, and extruding force acts on the fibrous material along this enveloping surface.
In order to make the fibrous material that the present invention relates to, melt or in a kind of solvent, dissolve a kind of polymeric material usually, then pull into continuous silk by spinning machine.Can implement different spinning processes in order to produce continuous silk, as the combination of dry-spinning method, wet spinning or dry-spinning and wet spinning.Make long filament in this process in spinning machine, long filament is pulled out from spinning machine by one or more draw-off mechanisms, and meanwhile they constitute tow or multiply silk.Then, long filament is further washing and post processing in the procedure of processing.
For example when producing staple fibre, the multiply silk that the continuous yarn by being arranged in parallel of pulling out from spinning machine before post processing are formed is imported cutter sweep.After leaving cutter sweep, constitute fiber web by staple fibre one by one usually, and be laid on the conveyer in order further to handle.
Staple fibre is made by Staple fibre cutting machines, for example carries out dried cutting by the machine that the 249-289 page or leaf is introduced in " Ullman-Band11, Fasern-Herstellungsverfahren ".
Viscose is as regenerated celulose fibre extrusion spinning in aqueous medium usually.In order to make staple fibre by spun continuous tow, for example be suitable for a kind of cutting machine, it mainly is made up of, real shearing device and staple fibre wash mill the roller that is used for tow is carried to shearing device.Shearing device will pull to the cutting knife that horizontally rotates from the tow that draw-off mechanism infeeds by an aqueous stream injectors.In cutting process, cutting knife keeps blade sharp by refacing of continuing.In addition,, before suspending, post-processor dismisses at the staple fibre bundle by supplying with the first time that water jet carries out the staple fibre bundle that forms in cutting-off process.For example produce this machine by Ing.A.Maurer S.A company.
Post processing for example viscose can maybe must be finished by a plurality of treatment steps.Typically implement following treatment step in the post-processor that viscose is used under the situation of supplying with treatment fluid: flexibilizing agent or grease coating are handled, are washed and apply in disacidify, desulfurization, washing, bleaching and washing, dechlorination.These treatment steps are implemented in an equipment usually, and the staple fibre that is called the cut-out of " bulk fibre " from cutting machine again arrives this equipment by levitation device, to constitute equally distributed as far as possible fiber web shop layer.
The equipment of handling fibrous material is designed to long unit traditionally, and in this unit, the fibrous material or the fibrous material that are scattered in the uniform fiber net are carried by each treatment region on conveyer.Can adopt belt conveyer, oscillating conveyor or eccentric slotted disk transporter (Exzenter-Rastenf rderer) as conveyer here, with for example circulate screen cloth band or metal wire knitted band.
When handling fibrous material, must be noted that, will manage the treatment fluid supplied with in the step throughout fast and be uniformly distributed in the fiber web of suspension.
Meanwhile advantageously, before implementing a treatment step, the treatment fluid of previous treatment step is got rid of from fibrous material as far as possible up hill and dale.
In order from fibrous material, to remove treatment fluid, adopt press-roller device usually, it applies an extruding force on fibrous material.By extruding force treatment fluid is extruded from fibrous material.The fibrous material that has extruded in the treatment step of following is used the treatment fluid dipping that matches with this treatment step again.Therefore, by press-roller device two treatment steps in succession are separated from each other.
Therein extruding force is acted in the zone that is crush zone on the fibrous material, behind the maximum extrusion pressure position,, constitute one nearby therein along zone that fibrous material throughput direction extruding force descends.This zone is called the breathing space.
In order to soak into fibrous material with treatment fluid, fibrous material moves on the conveyer below the spray pond usually.Directly after extrusion, treatment fluid is dropped on the fibrous material by the spray equipment that is positioned at its top.Yet this drippage of treatment fluid only causes a kind of uneven dipping of the fibrous material that just has been forced out and wetting.
A special problem occurred during the fiber web that constitutes in produce cellulose fibers or by cellulose fibre, they are by NMMO method or Lyocell manufactured.In this process, water, cellulose and the tertiary amine oxide extruding and the drawing-off that contain spinning solution are continuous silk.
Cellulose silk is subjected to big mechanical load when drawing-off.Long filament and the staple fibre produced by NMMO method or Lyocell method have high degree of crystallinity of cellulosic molecule or directionality.Because these are derived from the product performance of production process, cause the Lyocell fiber to tend to fibrillation.The implication of fibrillation is, because high-crystallinity and directionality make the circular fiber surface of single fiber split into little fibrillation.This fibril shape structure continues along fibre axis.
For reducing this fibrillation tendency, fiber can be handled with chemical cross-linking agent, and crosslinking agent is partial cross-linked on the fiber trunk with fibrillation.Usually control crosslinked or cross linkage process like this, that is with the plain tow of chemical cross-linking agent impregnation of fibers and cross-linking reaction by under higher temperature, beginning with steam treatment.
Crosslinking agent must add after fiber production in the fibrous material equably, and the temperature of fiber should be controlled where necessary, and washes out from fiber in treatment step subsequently.In addition, cellulose fibre as other non-cellulosic fibres, will carry out soft treatment and drying equally.
The problem that exists in this processing is that crosslinking agent tends to spontaneous chemical degradation reaction or hydrolysis, because chemicals is hydrolyzed in moisture environment or can not stablizes for a long time.When response parameter (for example reaction speed or reaction temperature) can not be observed exactly, will cause degraded and decomposition reaction equally.Therefore crosslinking agent must add in the enclosed areas under the situation of as far as possible accurately controlling course of reaction.Usually, crosslinking agent need join rapidly in the cellulose fibre, follows the quick adjustment temperature and as far as possible promptly washes out remaining chemicals subsequently and cooling meanwhile.So-called crosslinked during, effect raises on fibrous material temperature and alkalescence or acidic liquid.The chemical reaction of cellulose and crosslinking agent carries out under the situation of rising pH (for example about 11-14), causes the crosslinking agent hydrolysis thus.Crosslinking agent decomposes trend and can be contained by alap temperature in crosslinked pond.This low temperature can be in extruding device or preceding adjustment.After the crosslinking agent HEAT SETTING, that is crosslinking agent and cellulose chain must be removed from fibrous material in order to protect cellulose fibre alkali after reaction between about 20 and 98 ℃.
In addition, owing to fibre density and fiber swelling high in cellulosic fibre material, for the permeable fiber material must have the long time of staying, because only act on the little geography height that the liquid on it is arranged on fiber web, and the fibroreticulate pressure loss can only remedy by liquid long action time.
Traditional method and apparatus that wherein just sprays the fibrous material that is forced out with a kind of treatment fluid exactly for the treatment fluid of easy generation chemical reaction or decomposition, as crosslinking agent, is not meeting the demands aspect the accurate control procedure parameter.
Summary of the invention
Therefore, consider and be used in the method and apparatus that is in fibrous material usually, the objective of the invention is to improve described method of preface and the described equipment of preface, making can be as far as possible rapidly and distribution process liquid, thermoregulation agent (hot water, vapours and other heat carriers) in case of necessity and various washing agent in fibrous material equably, and thereby can realize process control accurately.
Is that to reach the measure that this purpose takes be that treatment fluid imports in the fibrous material by compressive surface in the breathing space for the described method of preface by the present invention.
For the described press-roller device of preface is to reach the measure that this purpose takes to be, press-roller device has some apertures in the breathing space, treatment fluid is imported in the fibrous material by compressive surface when the work by them.
This scheme is simple and advantage arranged, and treatment fluid can be very fast and be evenly distributed in the fibrous material that extrudes and be compressed and expand in the breathing space.Because extruding force reduces along the direction of motion of fibrous material in the breathing space, so fibrous material automatically sucks treatment fluid by compressive surface in this zone.Therefore the fibrous material that extrudes is all even takes place in crush zone with the treatment fluid infiltration apace.So can checking and compare, this processing procedure is easier to control.
Another advantage by the present invention program is that the structure length for the treatment of apparatus can significantly shorten.Opposite with traditional machine, there based on spray, the infiltration of fibrous material has only the action time of common length and fibrous material just can finish by the correspondingly longer transmission distance of treatment region, in pressing the solution of the present invention,,, fibrous material directly connects next treatment step so flooding the back with treatment fluid based on infiltration immediately.
That is to say, adopt that extruder might be designed to be similar to milling train, wherein, each roll along rolling direction directly each other in succession by the solution of the present invention.Therefore, by a kind of further developing of the present invention, when handling fibrous material, implement a plurality of treatment steps serially, fibrous material transmits by a plurality of press-roller devices in succession for this reason, always extrudes first kind of treatment fluid in the compressional zone and flood second kind of treatment fluid at the breathing space fibrous material in this process in a press-roller device from fibrous material.
Fibrous material is by independent for example carrying by crush zone for the transport of conveyer belt in form, and pressure roller rotates passively thereupon in this process.But pressure roller also can be established the drive unit of oneself.Can remove independent transport from this case, because pressure roller itself constitutes transport.The peripheral speed of pressure roller can 0.1 and 400m/min between, preferably 0.1 and 60m/min between, especially 0.1 and 10m/min between.Adopting these peripheral speeds, is 10 to 1500kg/ (m an accessible fiber throughput of treatment region
2H), preferably 10 with 1200kg/ (m
2H) between.The fiber throughput is to be calculated divided by the time of staying of each treatment region by the fibrous material weight that is in absolute dry condition, and it depends on the length of treatment region.
Before the breathing space, fibrous material can transmit by a compressional zone in crush zone, and extruding force increases along the direction of passing through of fibrous material in the compressional zone, so the treatment fluid that will be present in the fibrous material extrudes.By another favourable design, the treatment fluid that extrudes from fibrous material in the compressional zone can be derived by compressive surface.For this reason, can for example establish an aspirator, by it when work with treatment fluid from the compressional zone sucking-off.Can certainly only in compressive surface, establish some apertures and substitute aspirator, handle the cumulative extruding force of direction based on edge in the compressional zone, treatment fluid can pass through this aperture automatically, so almost no longer there is the treatment fluid from previous treatment step in fibrous material after fibrous material passes through crush zone.
The linear pressure that is pressed in the fibrous material by pressure roller of the present invention is the wide 100N of reaching of every mm roller.
As a supplement or be different from the compressional zone and derive or the sucking-off treatment fluid, treatment fluid also can import in the fibrous material by compressive surface before extrusion in order to wash fibrous material in the compressional zone.For example, fibrous material rinses out with the treatment fluid in the breathing space that infeeds the pressure roller that is connected the upstream in the compressional zone, so the treatment fluid that will be located at that treatment step of front, compressional zone along transmission or the throughput direction of fibrous material by this equipment not takes to along throughput direction and is located in the treatment step of back, breathing space.
For fibrous material can reach thoroughly and equably dipping with treatment fluid, by another favourable design, treatment fluid under pressure for example by be located at nozzle in the crush zone in the compressional zone and/or the breathing space be pressed in the fibrous material.The fluid flow that relates to the pressure roller width can be 0.1 and 125m
3(hm) between, preferably 0.1 and 50m
3/ (hm) between, especially 0.1 and 20m
3(hm) between.
In order to obtain a kind of special compact structure form, immersion system to the small part that treatment fluid is infeeded fibrous material by it is located at pressure roller inside.Treatment fluid can import in the fibrous material by the aperture from pressure roller inside by another design of the present invention in this case.Pressure roller can be provided with some apertures on its surface that faces fibrous material for this reason, and treatment fluid imports in the fibrous material by them.The aperture can be regular or brokenly in roller surface and nozzle-like cross section basically for example arranged.The opening degree of roller, that is the ratio of aperture area occupied and the total surface area of roller can be between 1 and 95%, preferably between 3 and 90%, especially preferably between 3 and 85%.
By another design, pressure roller also can face some ribs of surface design of fibrous material at it, and they constitute compressive surface to small part, and between them when work treatment fluid can import in the fibrous material.By another design, these ribs can extend substantially transversely to the direction of motion of fibrous material and extend.
Be the treatment fluid traction of two treatment steps avoiding separating by press-roller device, by another favourable design, rib can be designed to the weir, it prevents that treatment fluid from flowing to the breathing space and thereby having prevented traction by pressure roller from the compressional zone.This especially can accomplish when rib extends transverse to the fibrous material direction of motion.For this reason, the height dimension of rib can be designed to, and in crush zone, the upper end back to fibrous material of a rib between compressional zone and breathing space exceeds the treatment fluid level in compressional zone and/or breathing space all the time basically.
Especially in the design of the pressure roller of the rib that has the spacing of separating each other and preferably extend transverse to the fibrous material throughput direction, can be by another favourable design at some nozzles of the inner combination of pressure roller, by they when the work with treatment fluid vaporific or jet-like aligned fibers material in crush zone preferably.For preventing that treatment fluid is transported in the breathing space from the compressional zone by the pressure roller of rotation, nozzle also can be aimed at the compressional zone, so that desalination or squeeze there the treatment fluid that exists.If in the zone of fibrous material or at the injection conical surface of crush zone inner nozzle is overlapping basically, then reach fibrous material by treatment fluid complete wetting by the nozzle discharge.
According to the size of the treatment fluid type that is adopted, fibrous material and the composition of weight and fibrous material, be necessary treatment fluid being adjusted by the zone that compressive surface imports fibrous material by it.For this reason, immersion system can have regulator, adjusts the size and the orientation of treatment fluid discharge area in the compressive plane by it.By another favourable design, regulator can be designed to one for this reason and be contained in the covering that notch is arranged in the pressure roller, covering covers that should not flow through the compressive surface part or the pressure roller part of treatment fluid by it.Covering can for example be designed to one and be provided with cannelure and rotatably remain on tubular body in the pressure roller.
Replace or except from the treatment fluid input pipe of pressure roller inside, immersion system can have an input pipe, treatment fluid is imported in the breathing space basically from the pressure roller outside when the work always by it.By another favourable design, this input pipe can be located at two at least at least in part basically along between the rib of fibrous material direction of motion extension in crush zone.In this case advantageously, the section that input pipe faces compressive surface finishes with rib basically with flushing, so compressive surface is level and smooth as far as possible and produce low frictional resistance with respect to fibrous material.
At last, the invention still further relates to a kind of extruder that is used to handle fibrous material, press-roller device and a transport that is used for transmitting by extruder fibrous material that it has at least one extrusion fiber material here use by one of above-mentioned design described press-roller device.
In the extruder with a plurality of press-roller devices of connecting along the fibrous material throughput direction, these press-roller devices can be directly each other in succession.
Extruder and press-roller device can be with the operations of a kind of fibrous material, the absolutely dry weight of its per unit area 0.1 to 20kg/m
2Between, preferably 0.1 to 10kg/m
2Between.Can carry out post processing as fibrous material such as tow or heavy, thick fiber web.
Can adopt pure water, moisture organic or inorganic solvent, moisture or concentrated alkali lye and acid, bleaching agent, impregnating agent or inert gas, vaporous medium, heating or cooling medium and solvent vapo(u)r as treatment fluid.
In extruder, in the scope of crush zone, can establish another pressure roller in the face of this pressure roller, it is used to bear extruding force as the back-pressure device.This second pressure roller can be just like the identical design of first pressure roller recited above.In this design, fibrous material is guided through between these two pressure rollers.
Can adopt metal or plastics material as pressure roller, but their surface gluing, polishing or grinding.For avoiding damaged fiber, the limit of pressure roller and be located at aperture on the pressure roller in case of necessity and cavetto (gebrochen) is answered on the limit of rib.

The specific embodiment
The technical process of producd fibers material at first is described by Fig. 1.
Make a kind of press solution 2 in the system 1 that in Fig. 1, only schematically illustrates.For this reason, in one or more blenders by doing or wet debris is plain and water and/or tertiary amine oxide constitute a kind of suspension.Using the temperature that raises and under negative pressure, making suspension that water is evaporated to such degree, promptly forming a kind of cellulose solution as press solution.Preparation press solution 2 in reaction vessel 1.This press solution comprises cellulose, water and tertiary amine oxide, for example N-Methylmorpholin-N-Oxid (NMMO) and be used to make cellulose in case of necessity and the heat-staple stabilizing agent of solvent.Stabilizing agent can for example be: propyl gallate (Propylgalat) or the medium of alkalescence effect or mutual mixture are arranged.Can contain other additives in case of necessity, for example titanium dioxide, barium sulfate, graphite, carboxymethyl cellulose, polyethylene glycol, 2,5 dimethyl pyrazines, Ketusan, alginic acid, polysaccharide, pigment, play antibacterial action chemicals, the phosphorus that contains fireproof agent, halogen or nitrogen, active carbon, carbon black or conductive black, silicic acid and organic solvent as diluent etc.
Pipe-line system 4 is established the register (not shown), can accurately be controlled at the temperature of the press solution 2 that adopts as an example here by register, and establish the filter (not shown).This is necessary, because the chemistry of press solution and mechanical performance and temperature have confidential relation.For example the viscosity of press solution 2 reduces with the increase of temperature and/or the rising of shearing rate.
The apparatus for breaking of setting up defences in this external pipe-line system 4 is because press solution is tended to spontaneous exothermic reaction, so this is necessary.Because this rupture-protection arrangement is arranged, under the situation of spontaneous exothermic reaction, avoided pipe-line system 4 and equalizer tank 5 and be connected the extrusion head 6 in downstream because the contingent damage of reaction pressure.
Spontaneous exothermic reaction in press solution 2 for example occurs in and has surpassed certain temperature and especially in the slough under the rotten in time situation of press solution 2.For avoiding slough and separation flow occurring and guarantee that pipe-line system 4 flows through press solution equably, pipe-line system 4 is what help flowing in the whole zone design that flows through the high viscosity press solution.
In extrusion head 6, press solution is divided into many squeezing passages 8 of spinning capillary 8 that in form are in nozzle chambers.Spinning capillary 8 is arranged in Fig. 1 the row perpendicular to the figure paper plane.Therefore, make many continuous moldings simultaneously by single extrusion head 6.In addition, also can establish many extrusion heads 6, they constitute many continuous moulded bodies respectively, or constitute long filament under the situation of embodiment shown in Figure 1.In Fig. 1, only drawn a spinning capillary 8 in order to simplify.
The spinning capillary has the inside diameter D less than 500 μ m usually, and for special application, this diameter also can be less than 100 μ m, preferred about 50 to 70 μ m.
Being extruded the spinning length L capillaceous that flow of solution crosses is the twice of inside diameter D at least, is at most 100 to 150 times of inside diameter D.
Spinning capillary 8 to small part is centered on by heater 9, can control the wall temperature of spinning capillary 8 by it.The wall temperature of spinning capillary 8 is about 150 ℃ when work.The temperature of spinning solution when work between about 80 and 130 ℃.Spinning capillary 8 can be placed in any formwork of external control temperature or in the carrier, and making has high hole density in the extrusion head 6.
By heating squeezing passage directly or indirectly, wall and based on the viscosity of the press solution that depends on temperature within it constitutes one and is the mobile film of low-viscosity heating with respect to flowing of heart portion.Therefore velocity profile and the extrusion process in squeezing passage 8 inner press solution advantageously changes, and makes the spinning solution that is extruded reach better not kink property and lower fibrillation tendency.
Squeeze out press solution in squeezing passage 8, the form with long filament 11 enters in the air gap 12 then.There is a height H air gap along press solution flow direction S.
In air gap 12, air 13 is supplied with the press solution of discharging from extrusion head 6 with high speed.Flow direction can flatly be guided until extrusion spinning; The flowing velocity of air 13 can be discharged continuous moulded bodies with this speed from the squeezing passage mouth greater than the extrusion speed of long filament 11.By the air flow of coaxial guiding basically, tension of effect on the interface between continuous moulded bodies 11 and the air 13 can drawing-off continuous moulded bodies 11 by it.
After passing air gap 12, continuous moulded bodies enters and solidifies bath of liquid district 14, and it uses the wetting or humidification of solidification liquid in this district.Wetting can the realization by spray or damping device (not shown) maybe can be realized by continuous moulded bodies 11 is immersed in the solidification liquid bathing pool.Make the press solution stabilisation by this coagulation bath.
Another possibility is, after solidifying bath of liquid district 14, is laid on the transport 15 to continuous moulded bodies 11 essentially no tensions.Transport 15 is designed to vibrating conveyer.Because the reciprocating motion of vibrating conveyer 16, continuous filament yarn is placed on transport and piles up 17 orderly.Because this no tension ground transmission on transport 15, can steady and continuous molding 11, can not apply injurious effects to the mechanical performance of continuous moulded bodies 11, these injurious effects for example are soon because mechanical load is issuable prematurely after continuous moulded bodies 11 extruding.
Depend on design, continuous moulded bodies 11 is pulled out by pulling device 18 before or after transport 15, and through turning to or transport 19 supply cutting machines 20.Adjust corresponding fiber parameter by pulling device 18, as fiber number, intensity and percentage elongation.
A lead-in portion extrusion head 6 or import the continuous moulded bodies 11 of whole extrusion heads 6 abreast in cutting machine 20.A roller is housed to (not shown) in cutting machine 20, is used for the continuous moulded bodies bundle 11 of different extrusion heads 6 is supplied with shearing device, that is real shearing device (not shown) and staple fibre wash mill (not shown).The shearing device (not shown) will pull to the cutting knife that horizontally rotates to the tow that infeeds from pulling roll by an aqueous stream injectors.By cutting knife fibrous material is cut off by predetermined length.Cutting knife is sharp by the maintenance blade of refacing that continues in cutting-off process.By supplying with water jet, before the suspension of staple fibre bundle becomes fibrous material, carry out the dismission first time at the staple fibre bundle of cutting-off process formation.
Discharge the fibrous material 21 of straw mats shape basically from cutting machine 20, it is with the water of supplying with in cutting-off process flotation in an equipment 22 that is used to handle fibrous material 21.Fibrous material 21 constitutes by the omnidirectional configuration of the fiber of cut-out in cutting machine 20.
The equipment 22 that is used to handle fibrous material 21 constitutes object of the present invention basically.
Implement typical treatment step for viscose in equipment 22, flexibilizing agent/grease coating or other chemicalss are handled, are washed and apply in for example disacidify, desulfurization, washing, bleaching and washing, dechlorination.Various processes or stage carry out in treatment region 23,24,25,26,27 respectively, and they separate each other by press- roller device 28,29,30,31,32,33.In each treatment region 23 to 27, the treatment fluid that respectively a kind of treatment region for this reason or treatment step is set by immersion system 34,35,36,37,38 imports from corresponding storage tank 39,40,41,42,43.Treatment region has the spacing at least about 0.5m to the roller center from the roller center along the fibrous material throughput direction, but this spacing also can reach 10m and bigger according to the requirement of processing procedure.Under extreme case, each press- roller device 28,29,30,31,32,33 also can just in time not contact pressure roller each other directly in succession.
Press-roller device 28 to 33 can be designed to paired roller as shown in Figure 1, or also can be designed as the isolated roller of a fixed back-pressure face.The extruding force of roller can produce and can for example mechanically produce by lever force by electricity, hydraulic pressure or pneumatic approach.The wide 100N that reaches approximately of the every mm roller of the typical extruding force of pressure roller.
By the extruding force that is applied by press-roller device 28 to 33, treatment fluid that will adding in dealing with district 23 to 27 separately extrudes from fibrous material, and prevent with treatment fluid from that treatment step traction of front to next treatment step.
After passing through equipment 22, fibrous material 21 can resupply other treatment steps that does not have expression in Fig. 1.The drying device that the shredding unit is for example arranged can be used for fibrous material dehumidifying and shredding, and is attached thereto a packing unit that connects, and can be used for making the product that a packing finishes and can send.
Fig. 1 as case representation by the spinning solution producd fibers material of cellulose.But equipment 22 is not limited to be used in cellulose fibre, but can be used in fibrous web-like or woven fibrous material with the long filament system of other compositions equally.In order to produce this fibrous material that constitutes by non-sticky or non-cellulosic fibre, by known other manufacture methods of prior art.
Below as press-roller device of example explanation.Because the basic function of press-roller device 28 to 33 all is identical, so only describe a unique press-roller device in the following description as an example in detail.
Fig. 2 represents to be used to handle the section of 50 first kinds of embodiment of press-roller device of fibrous material 21 perpendicular to fibrous material 21 direction of motion B by the present invention.
The press-roller device of representing in Fig. 2 is applied to little speed washing tow or washing staple fibre and is applied to big fibrous material, and wherein, fibrous material moves with the speed of about 40m/min along throughput direction.This speed is equivalent to the extrusion speed of continuous moulded bodies on extrusion head.At absolutely dry fibrous material weight per unit area is 0.1kg/m
2The time, the fiber throughput is about 52kg/ (m
2H), wherein, treatment fluid is wide with every m roller to be 125m
3/ (hm) flow infeeds.
Press-roller device 50 has a pressure roller 51, and it can be rotated to support on the supporting arrangement of not representing among Fig. 2, and along the move rotation of direction of arrow P with fibrous material 21.Pressure roller 51 is pressed in the fibrous material 21 with extruding force F.Constitute a compressive surface 52 in this process, it is the enveloping surface around an imagination of pressure roller 51, will be acted on the fibrous material 21 by the extruding force that thrust F produces by this enveloping surface.
To be called crush zone 53 via the zone that compressive surface 52 acts on the fibrous material 21 as the thrust F of extruding force by it.Along the direction of motion B of fibrous material 21, at first extruding force increases up to pressure roller substantially 51 and invades fibrous materials 21 innermost those zones in crush zone 53.The zone that increases along fibrous material 21 direction of motion B extruding forces hereinafter claims compressional zone 54.Along fibrous material 21 direction of motion B, breathing space 55 is connected with compressional zone 54, and extruding force reduces again along the direction of motion B of fibrous material in the breathing space.
In compressional zone 54 because extruding force increases gradually, so the treatment fluids 56 that are absorbed in the fibrous material 21 be forced out, compressional zone 54 ends almost no longer fibrous material 21 in existence from the treatment fluid 56 of the treatment step of front.
In the embodiment of Fig. 2, pressure roller 51 is provided with through hole 57, and they extend to the pressure roller outside from pressure roller inside.On the outer circumference surface 59 of pressure roller 51, through hole 57 ends at groove 58, and the diameter of groove is greater than the diameter of through hole 57.Groove also can be processed into long groove shape and correspondingly distributes along circumference along the pressure roller axis.
When roller diameter was 400mm, the diameter in these holes was between 3 to 12mm.The opening degree of pressure roller 51 basically and its diameter irrespectively between about 5 to 40%.
Through hole 57 can random distribution, embark on journey vertically or along circumferential row, or arranges mutually on outer circumference surface 59 with staggering.
In the embodiment of Fig. 2, the inner part that constitutes immersion system of pressure roller, treatment fluid imports in the fibrous material by immersion system.
Establish a covering 60 in pressure roller 51 inside, it is designed to tubulose basically and has one along the pressure roller 51 axially extended formal openings 61 of groove that are, groove face is facing to crush zone.This covering 60 does not move with pressure roller 51, but fixing.In its each end that faces groove, covering 60 is provided with seal 62, does not enter between covering 60 and pressure roller 51 inner peripheral surfaces 64 from the inner chamber 63 of pressure roller 51 so do not have treatment fluid.
Covering 60 is used to constitute the border in zone 65, and treatment fluid adds in the fibrous material 21 by this zone 65.Press Fig. 2,65 mainly extend in the scope of breathing space 55 in the zone, but also (at least in part) in the scope of compressional zone 54, extend.If the treatment fluid that for example can be under 2.5 to the 3bar pressure is guided by through hole 57 from pressure roller 51 inner chambers 63, then the treatment fluid from the treatment step of front that schematically illustrates in Fig. 2 in compressional zone 54 of this treatment fluid rinses out, and meanwhile it is inhaled into owing to capillarity and fibrous material 21 reduce to produce to expand based on pressure in breathing space 55.Consequently people have obtained a kind of treatment fluid that imports by pressure roller 51 or compressive surface 52 and evenly and have fast distributed.In order to adjust the position of groove 61 with respect to crush zone 53, this first covering 60 can be in pressure roller 51 around its longitudinal axis X coaxial rotation fix, as representing with four-headed arrow A.
Fig. 3 represents embodiment illustrated in fig. 2 further developing.Below only describe in detail and difference embodiment illustrated in fig. 2.
The press-roller device of Fig. 3 can for example be used for washing and have the about 4.1kg/m of weight
2Cellulose bondedfibre fabric as fibrous material 21.In this used, fibrous material moved along throughput direction with the about 0.1m/min of speed.The wide fiber throughput of every m roller is about 40kg/ (hm in this type of is used
2).Treatment fluid is 0.7m with the flow
3/ (hm) infeed.
Different with monoblock type covering shown in Figure 2 60, by in the further developing of Fig. 3, covering is divided into two covering 60a and 60b.Each and another covering irrespectively can be fixing rotationally around its longitudinal axis X on the inner peripheral surface 64 of pressure roller 51 among two covering 60a, the 60b.Therefore in the press-roller device 50 of pressing Fig. 3, by adjusting covering 60a, a 60b or two covering 60a, 60b, not only can change angular aperture α but also can change the method for groove 61.For the inner chamber 63 of the pressure roller outside the zone that is sealed in groove 51, establish seal 66, it covers movement slots 67, and this movement slots is made of two covering 60a, 60b equally and guarantees that two covering 60a, 60b can relative motions.Seal 66 can be contained in covering 60a, 60b inside, or by another kind of selectable design, is located between covering 60a, 60b and the pressure roller 51.The seal that is shaped on cannelure 66 of tubulose is provided with seal 68 in its end, and they prevent between treatment fluid intrusion covering and the seal.
Can utilize big mutability aspect treatment region 65 sizes and position in the embodiments of figure 3, implement to mate exactly with separately treatment step and with the wetting requirement of the treatment fluid of in this step, supplying with.
With the give an example one-sided adjustment of left covering 60b in the presentation graphs 3 of imaginary line, 65 of treatment regions are seated in the breathing space 55, by this treatment region treatment fluid is imported fibrous material 21.
Fig. 4 represents second kind of embodiment by press-roller device of the present invention.Here, structure or consistent with the member of the front embodiment basically member of function aspects for them adopts same symbol.
In the embodiment of Fig. 4, pressure roller 51 is made of many ribs 70 that extend along the axial X of pressure roller 51.These ribs have radially from pressure roller 51 interior outwards cumulative wall thickness.In its outside, rib 70 constitutes compressive surface 52 at least in part in crush zone 53.Rib 70 is fixed on fixed disk or the retainer ring end of X vertically in compressive surface respectively.Rib 70 all extends parallel to each other and identical spacing is arranged each other, and the zone 71 that is between them is empty (not having material) basically.Rib 70 each other can be by being connected to each other along the plate-like of circumferentially extending or the support of ring-type, so they have higher mechanical stability.
In design shown in Figure 4, the opening degree of pressure roller 51 is assigned between 90 and 95% in individual cases.The quantity of rib between 30 and 80, preferred about 60.When the pressure roller diameter is 400mm, rib along circumferential width 1 and 20mm between, wherein, although adopt the rib of broad can obtain bigger pressure, fluid flow is less.
Otherwise this immersion system also can use with the covering 60 that has illustrated there by the embodiment of Fig. 2 or 3.
In addition, immersion system 72 is established one or more nozzles 74, their aligned fibers materials 21.Treatment fluid flows into fibrous material 21 from central input pipe or collector tube 73 by each nozzle 74 with between rib 70.
Fig. 5 represents the cross section perpendicular to axial X embodiment illustrated in fig. 4.
As seen from Figure 5, form an injection conical surface 75 respectively, wherein, spray the conical surface 75 and overlap each other, make in crush zone 53, not have the not zone of processed liquid wetting by the treatment fluid of discharging from nozzle 74.Spraying the conical surface 75 can be taper shape or plane.
For preventing treatment fluid 56 tractions to the zone that is positioned at crush zone 53 downstreams along fibrous material 21 direction of motion B, being designed and sized to of the height H of each rib 70, make the rib that has been in basically in the crush zone 53 constitute the weir, owing to there is this weir that treatment fluid can not directly be flowed between the zone of crush zone both sides.
Because rotation D by pressure roller 51, treatment fluid might be transported to next treatment step from a treatment step by the space 71 between per two ribs 70, so with a nozzle 74 ' aligning compressional zone, so that rinse out the treatment fluid 56 that might flow into from the treatment step of front there.
By regulator 78, for example by nozzle 74 is installed in can relatively rotate with respect to each other and with the concentric pipe 76 of input pipe 73 on, can adjust the size and the orientation of treatment regions 65 by moving nozzle 74.
Rib be along circumferential should being defined as apart from size of each interval, and making can be by the treatment fluid of q.s between the rib and meanwhile still can in crush zone 53 extruding force be acted on the fibrous material 21 equably.
Fig. 6 represents the perspective view by the third embodiment of press-roller device 50 of the present invention.Wherein for the member of its 26S Proteasome Structure and Function aspect and the member unanimity of front embodiment adopt with in front embodiment in identical symbol.
In addition, press-roller device 50 has two immersion system 72a, 72b, and they are located at the both sides of pressure roller 51 with respect to the direction of motion B that does not have the fibrous material of expression in Fig. 6 for simplification.
Each immersion system 72a, 72b have one to be parallel to the collector tube 73 that pressure roller 51 axial X extend, and input pipe 80 extends in the crush zone 53 in the space 71 of collector tube between rib 70 always.
In the embodiment of Fig. 6, the input pipe 80 of two immersion system 72a and 72b is connected to each other and is integral, so treatment fluid flows to the collector tube 73 of immersion system 72b from the collector tube 73 of immersion system 72a, and a part of treatment fluid is by mouthful entering in the crush zone 53 of the input pipe 80 of expression not among Fig. 6.
Mode as an alternative, the input pipe 80 of immersion system 72a and the input pipe 80 of immersion system 72b also can be separated from each other, so the different treatment fluid that is and imports by immersion system 72b that imports in crush zone 53 by immersion system 72a.Thus can enable pass crossing processing that press-roller device 50 implements has bigger changeability and with different fibrous material and treatment fluid better suitability is arranged.
The Cross-section Design of input pipe 80 is consistent with the cross section in space 71 basically also thereby fill up space 71 basically for it.Treatment fluid imports crush zone 53 by the mobile S of collector tube 73 via these input pipes 80 always.Especially this situation as can be seen in Fig. 7 is represented an end-view along fibrous material 21 direction of motion B embodiment illustrated in fig. 6 there.
Input pipe is expressed as in the scope of crush zone in Fig. 7, especially the part section in breathing space 55 scopes.
Input pipe has some apertures 81 in this zone, treatment fluid enters space 71 and enters fibrous material 21 by compressive plane 52 by them.
With shown in Figure 7 different, the part that input pipe 80 faces fibrous material 21 also can contact with fibrous material 21.But should take special counter-measure for the surface quality and the ABRASION RESISTANCE of input pipe 80 in this case, be worn and torn in advance by the fibrous material 21 of process under pressure to prevent damaged fiber material 21 and input pipe 80.
Press in another design of Fig. 6 and 7 described embodiment, in front that immersion system 72a also is designed to aspirator for fibrous material 21 direction of motion B, for example extracts treatment fluid by it out from the compressional zone by the apertures 81 in the input pipe 80.
Also represented drive unit 82 among this external Fig. 7, for example motor drives the synchronized movement ground rotation of pressure roller 51 and fibrous material by it.This drive unit 82 also can be applied among other embodiment.Pressure roller itself can be used as the transport of fibrous material 21 in this design, and fibrous material 21 transmits by the extruder various processes by it.
Fig. 8 represents that by the 4th kind of embodiment of press-roller device 50 of the present invention is parallel to fibrous material 21 direction of motion B and perpendicular to the section of pressure roller 51 axial X.Press-roller device 50 by Fig. 8 has an anti-roll 90, and it is with a thrust F with pressure roller 51
1The opposite extruding force F of size equidirectional
2Be pressed in the fibrous material 21.Both have identical structure pressure roller 51 and anti-roll 90, and this structure is consistent with the structure of first kind of embodiment represented in Fig. 2 and 3.
Therefore for simplicity, for the embodiment of Fig. 8, its 26S Proteasome Structure and Function adopts identical symbol with those members of the member unanimity of front embodiment.
In the embodiment of Fig. 8, as use arrow S
1Schematically illustrate like that, breathing space 55 in from the treatment fluid of the treatment step of front by anti-roll 90 extractions, and in breathing space 55, as use arrow S
2That represents is such, and the treatment fluid that is used for next treatment step imports fibrous materials by pressure roller 51.
As the alternative of this design, each roller 51,90 not only can play aspirator but also can play immersion system in crush zone 53.
As among Fig. 1 by equipment 22 expression, when in extruder 22, using by press-roller device 50 of the present invention, can directly connect the press-roller device that is given for next treatment step, because by compressive surface 52 dippings, be evenly distributed in immediately in the fibrous material 21 so treatment fluid takes place based on fibrous material 21.
Significantly shorten the structure length of extruding and treatment facility 22 thus.
Owing to distribute equably immediately at this of fibrous material 21 inside, the capillary support that this distribution obtains fiber spacing little in breathing space 55 again and causes thus is so can implement and more easily control dipping process exactly.Also might flood thus with those treatment fluids that care should be used to is grasped tending to spontaneous chemical reaction in some cases.
Also can be used in other positions of fiber production apparatus by roller of the present invention, for example as the pulling roll that comprises the last cured device in being combined in.
Except the fibrous material that constitutes by cellulose as example explanation, fibrous material with natural or synthetic fiber system also can be by pressing equipment of the present invention and pressing method processing of the present invention, for example fibrous material that is made of viscose, acetate fiber, polyester, polyamide and acrylic fiber.
Enumerate some concrete examples in order to further specify the foregoing description tabulation below.
In the example 1 to 4 of following table, the tow of making by the Lyocell method is processed into the staple fibre shape by wet cutting machine, and is placed on the treatment facility 22 as fibrous material 21 at this state.It is starting point that the weight data that wherein relates to is in absolutely dry state with fibrous material.In example 5, tow is directly supplied with treatment facility 22 as fibrous material 21 under situation about not cutting off in advance.Make water as treatment fluid all in for example.In whole example 1 to 5, equipment 22 is designed to, and permeates fully along the processed liquid of its full depth at each treatment region fibrous material 21.
| Example | 1 | 2 | 3 | 4 | 5 | |
| Dipping by means of | Spray | Roller | Roller | Roller | Roller | |
| The type of roller | - | Fig. 4 | Fig. 4 | Fig. 2 | Fig. 2 | |
| State | Staple fibre | Staple fibre | Staple fibre | Staple fibre | Tow | |
| The linear pressure of every mm pressure roller width | N/ | 12 | 12 | 10 | 10 | 10 |
| Every m 2The fibrous material of treatment region area | kg/m 2 | 7.2 | 7.2 | 3.1 | 4.1 | 0.1 |
| Washing speed | m/min | 1.5 | 1.5 | 0.3 | 0.1 | 36 |
| The wide fluid flow of every m roller | m 3/hm | 15.4 | 15.4 | 2.5 | 0.7 | 125 |
| Every m 2The fiber throughput of treatment region | kg/m 2h | 324.8 | 1299.4 | 93.8 | 41.3 | 51.6 |
The dipping of fibrous material is undertaken by spraying fibrous material with treatment fluid in the pressure roller downstream along throughput direction by the method for prior art in example 1.In the method, fibrous material 21 is not permeated after meeting with treatment fluid immediately fully, so treatment fluid accumulates in above the fibrous material as the lake and can only pass through fibrous material 21 seepage flow gradually.The formation in this lake increases with the increase of fibrous material thickness.Fibrous material only permeates fully fibrous material has the situation of long residence time more in treatment region under with treatment fluid and just can reach.Treatment region must have corresponding length along the throughput direction of fibrous material by treatment facility for this reason.
Then opposite in example 2, handle by under in addition consistent treatment conditions, implementing with example 1 by the pressure roller of the present invention's design.As by comparative example 1 and 2 as can be seen by table, in example 1, that is the scheme of pressing prior art, every m
2Much smaller than in example 2 of treatment region and fiber throughput hourly.
The same use by pressure roller of the present invention in example 3 to 5, so fibrous material permeates when contact with liquid immediately, and the treatment region that does not need to grow is used to make fibrous material to permeate fully.Therefore, the more all even liquid of distribution process more quickly in fibrous material consequently in these forms of implementation.
