Description
Technical field
The present invention relates to yarn be handled, make yarn before Woven fabric or other final products, have desired characteristics with treat liquid.
Background technology
In textile technology, use of the processing of reagent liquid to yarn, can be widely used in many technical process, to different classes of fiber such as cotton, wool, silk, flax etc., this processing can make yarn obtain desired characteristics, perhaps removes the unwanted composition that can reduce its use value and potentiality.For example, for cotton fiber, this processing can relate to dyeing, mercerising, bleaching, rinsing, starching etc.
In generally popular industrial practice, these handle operation is with many discontinuous yarns, the yarn that particularly is prepared into a yarn or reeled yarn form carries out batch operation to be realized, these yarns or reeled yarn must be by unwinding and processing more by different way on production line after handling.
The batch processing of yarn normally extremely bothers, owing to wherein need considerable labour, the poor efficiency of treat liquid, the relevant environmental problem with high investment and that finally cause of factory owing to the residual reagent in the waste water, therefore this need more expense to be used to guarantee that draining is up to standard.Also there is other problem in batch operation, the quality homogeneity of each batch product can because the parameter in each single batch processing for example temperature, time, concentration etc. difference and change.
Therefore with handling economy, high efficiency and the quality homogeneity that yarn is handled continuously, be conclusive to the business success of whole yarn production.
Use treat liquid yarn to be carried out the characteristics of processed continuously system in order better to illustrate, in specification of the present invention, caustic dip technology with reference to the cotton fiber under the tension force---also make mercerising handle and be described, this technology is being represented with the exemplary of handling the liquid handling yarn; Should point out clearly that yarn continous processing system of the present invention can also advantageously be applied in other processing of yarn in the textile technology.
In known technology, mercerising is specially adapted to the reeled yarn by doff operation preparation, through caustic dip in batches, and rinsing then, oven dry, unwinding and be prepared into a yarn again.
And then in a broad sense, mercerising adopts the alkali lye of high concentration---normally caustic soda but also can be with other alkali compounds---processing yarn carries out drawing-off.The mercerising of cellulose yarn is handled the mechanical performance that can improve yarn, and strengthen the glossiness of yarn and improve absorbent properties and respond running product, and to the compatibility of dyestuff.The single fiber that this enhancing occurs in yarn is in the semi plastic stage that causes owing to the concentrated base dipping.
Also to using mercerising solution that yarn treatment has been proposed suggestion, the mercerising of yarn at first is wound up into each one thread on axle in handling in known technology, and every has the hundreds of one thread on axle.These yarns are from unwinding abreast on axle, respectively by a series of normal pressure grooves down that fill alkaline bath and other treatment fluids, also are wound up into other through on the axle or be wound up on the single bobbin by roller again to yarn being carried out drawing-off.
The bobbin of the yarn that mercerising was handled is loaded into bobbin winder then and is made into a yarn.These technical schemes are very complicated, and they have, and many defectives are therefore very not large-scale in the market yet to be popularized.For example, the size of alkaline bath groove is very huge; This has caused the expensive and technical immovability of factory, and the poor efficiency of alkaline bath groove.The surface that the alkaline bath groove is huge directly contacts with air, and the NaOH in the groove goes bad soon because contact the carbonation that produces with the top carbon dioxide in air.The fracture of any one thread all is difficult to discover and the very difficult recovery of Yarn break in the processed yarn, and processing under any circumstance all must be interrupted.
Summary of the invention
An object of the present invention is to provide and a kind ofly with treat liquid yarn is carried out processed continuously system, this system can overcome the defective that this type systematic exists in the known technology.

The present invention also provides a kind of yarn continous processing system, and the mercerising that is specially adapted to yarn is handled, and it is characterized in that comprising: the preparation of the wire harness of single yarn or threads and feed unit; Be used to handle the device of yarn, comprise one or more tubular reactors, at described tubular reactor place jet pipe in the venturi is arranged, jet pipe feeds treatment fluid in this venturi as pressurised driving liquid, by the suction of this driving liquid and carry wire harness, described reactor has output in the lower end, by distributing roller wire harness is pulled out, drafted subsequently roller drawing-off, described drawing roller is rotated with the speed higher than distributing roller.
As described herein, in following illustrative and nonrestrictive description, will seem more obvious with treat liquid to characteristic and the advantage that yarn carries out processed continuously system, following description explanation is to handle at the continuous mercerized cotton yarn of cotton fiber under the tension force to carry out, and the layout of equipment is shown as Fig. 1.
Description of drawings
Fig. 1 shows the total arrangement that carries out the system of yarn treatment with treat liquid.
Fig. 2 shows the change example of the embodiment of mercerising tubular reactor among the present invention.
The specific embodiment
In the overall plan of Fig. 1, processed yarn 1 is fed from a series of tube yarn 2 beginnings, tube yarn 2 is placed in parallel in one for succinct former thereby on the specific unwinding tube frame that does not illustrate on the figure, the many parallel yarns of its unwinding, these yarns are assembled to form a wire harness 4 together adhered to one another in a rope Split Down funnel 3.In theory, method and apparatus of the present invention also can be used for the processing of single yarn 1, but commercial Application of the present invention is more noticeable, and---because its high production rate and high efficiency---assembled a lot of one threads in the wire harness 4, preferably wherein include 20 to 200 even threads more, this depends on processed amount of yarn and characteristic.
Compactness for the yarn that comprises in the wire harness 4 that improves processed yarn, as described in the preferred embodiments of the present invention, zone 6 at the wire harness preparatory process, has the very boost line 5 of long loop (long coils) with at least one, shed open (shed) with 200 to 1500mm is by above described wire harness, in the processing procedure of wire harness, follow wire harness, subsequently in the last separated of process for producing line and be recovered.Under the situation that 1 fracture of one or more line is arranged, this means can prevent that the yarn of these fractures from can not continue to move and pass whole unit and along with continuous feeding occurs in a phenomenon of gathering in the continuous processor group.
For example, as shown in Figure 1, described coiling realizes by the auxiliary yarn 5 that one or more has higher chemistry and mechanical stability---for example the yarn of being made by Kevlar fabric 5---, and it is provided by one or more bobbins 8, bobbin supports for rotation coil holder succinct former thereby that do not express on figure by one, and boost line is turned round on wire harness 4 and according to the direction of arrow A.Another improves in wire harness 4, and the method for combination is that wire harness itself is added slight sth. made by twisting between yarn, and every meter a few sth. made by twisting is assemblied on the revolving platform according to the unwinding tube frame of putting down in writing in the rope making technology with tube yarn 2
Form pulling by a pair of cord roller 10 of wire harness 4 each root line and realize, they are according to the speed revolution of controlling and determine that thus the linearity of the wire harness 4 of processed yarn pulls speed, delivers to the mercerising reactor with hundreds of meters/minutes speed with it usually.
A key property of the present invention is the structure of treatment process and reactor, and the processing of wire harness 4 is finished by treat liquid in reactor, and in specific descriptions of the present invention, treat liquid is made up of the NaOH alkalescence aqueous solution of high concentration.This operation is carried out in a tubular reactor 15, and this reactor has a vertical axis, and is equiped with an injector or venturi tube 16 at the position that it begins.
The pressurised driving liquid that injector or venturi tube 16 are made up of the mercerising alkaline solution by feeding, for example be that concentration is the NaOH of 30 ° of Be, be equivalent to 297g/l, wire harness 4 is entered reactor 15 by break-in roller 9 guiding, and this reactor 15 has a consistent inlet aperture of negative pressure with venturi tube 16 liquid contraction mouths.Liquid suction wire harness 4 is also pulled the control of the guide roller 10 that the d/d speed of wire harness is begun from tube yarn 2.Wire harness passes along the axis direction of tubular reactor, leaves with mercerising liquid from the outlet 17 of reactor below.The inlet pressure of treat liquid is regulated, and contraction mouth feasible and injector 16 is consistent, and the speed that obtains driving liquid changes in the scope of 12 to 40 meter per seconds, preferably from 15 to 20 meter per seconds.Observe,, obtain a higher mass exchange coefficient in fiber and the fibre bundle gap between the liquid in tubular reactor, can reduce widely contact time simultaneously so can make because higher turbulent flow takes place.Subsequently washing and in and in the tubular reactor of operation, also can observe same exchange efficiency.
The feeder 18 of a mercerising solution is installed in injector tubulose reactor 15 belows and exports corresponding to direction.On the other hand, wire harness 4 is immersed in groove 18 at one and collects under the effect of angle pulley 19 in the liquid and move upward once more, pass squezzing group 20 of pine again, its loose roller 21 by one or more pairs of mutual extruding is formed, and it squeezes the excessive solution that oozes in wire harness 4.Groove 18 has one in order to keep the overfall of inner liquid level; Alkalescence mercerising solution is collected from described groove, filters, and readjusts concentration and temperature, is reproduced according to known technology then and is used in the mercerising zone.
As everyone knows,, equally wire harness 4 is also had such effect because the effect cotton yarn of alkaline mercerising solution can produce expanding and shorten clearly, thus the porch wire harness in rice/minute initial flow-rate can clearly reduce in the exit of reactor.For example, its corresponding wire harness has only 600-700 rice to the wire harness 4 of 1000 meters of porch in the exit.
The wire harness that rises is by the effect control of compensator 25 and the tension value of adjusting wire harness, compensator specifically illustrates in Fig. 2 subsequently, wire harness is comprised that the drafting system 30 of distributing roller 31 upwards pulls, distributing roller with reactor 15 in handle the corresponding to wire rate running of the shortening cause, for example with the 60-70% of wire harness 4 in the arrival rate at venturi tube 16 places.Because the effect of drawing roller 32, distributing roller 31 is done the time spent in the drawing-off of wire harness 4 and is also played nip roiler, drawing roller is positioned at the downstream of nip roiler and with the speed running higher than roller 31, for example with 90% running of wire harness 4 in the arrival rate at venturi tube 16 places, therefore can recover the most shortening that produces in the yarn fibers 1, and be provided as and to obtain the necessary tension force of mercerising beneficial effect fully.Yarn is discharged from from the effect of mercerising unit by break-in roller 33 then.
Processing in the mercerising unit can be repeated one or many in case on processed cotton fiber the accumulated process effect.For illustrative purposes, Fig. 1 shows second a mercerising reactor 15 ' with all fours in front.The parts that identical Reference numeral representative is identical also have identical functions.
Equally in second reaction process, alkaline mercerising solution makes the yarn that forms wire harness 4 produce again to expand and shortens, so it is pulled by distributing roller 31 ' corresponding to wire rate of new shortening of generation with reactor 15 ' middle the processing time.Distributing roller 31 ' and drawing roller 32 ', for example the mode with all fours roller noted earlier turns round, and to produce the wire rate running of similar tension force, makes the length response rate of wire harness reach wire harness 4 in 90% of venturi tube 16 place's arrival amounts at first.Yarn is sent by the effect of break-in roller 33 ' then.
Handle better and make yarn produce a new shortening at second reactor 15 ', its zone line quilt drawing-off once more between roller 31 ' and 32 ' for example returns to it with respect at 90% of the initial length at guide roller 10 places.
Be directed into by the wire harness 4 behind the mercerising of directed roller 33 ' guiding and carry out first rinsing process in the unit 40, rinsing is finished in the effect of jet pipe 41 in the venturi of the washings pressure current that comes from operation subsequently by feeding.Be similar to preceding road mercerising reaction process, it is lateral opening that wire harness enters of venturi tube 41, and this lateral opening direction is consistent with the negative pressure direction of the liquid contraction mouth of suction wire harness 4, formed contact closely between mercerized yarn that forms wire harness and washings.Be similar to previously described mercerising unit, wire harness 4 and washings leave venturi tube 41 together, and washings are collected in the mercerising solution feeder 42.On the contrary, wire harness 4 moves upward under the effect of a loose break-in roller 44 once more, pine break-in roller is immersed in the water of groove 42 collections, the squezzing group 45 of wire harness by forming by one or more pairs of mutual loose rollers 46 of pressing, and this squezzing group squeezes out the excessive treatment fluid that oozes in wire harness 4.Similarly, groove 42 provides an overfall 47, and washings are recovered and utilize again from overfall.
Its tension value is controlled and regulated by the effect of compensator from the wire harness 4 that rinse unit rises, be similar to the compensator of describing among Fig. 2 subsequently 25, the last drafting system 51 that is quite analogous to drafting system 30 and 30 ' then upwards pulls.Last drafting unit 51 between two rinsing processes is made up of a pair of nip roiler and a pair of subsequently drawing roller 53, and for example, they are used to recover the initial length of wire harness 4.Wire rate running when nip roiler leaves venturi tube 41 bottoms with wire harness 4.For example, on the other hand, drawing roller subsequently is to arrive the same line speed running at first venturi tube 16 places, therefore can recover the whole shortenings that produce in the yarn 1 fully and significant mercerising tension force is provided.Yarn is discharged by break-in roller 55 then.
Again for illustrative purposes, Fig. 1 has provided second rinse unit 40 ' that is quite analogous to unit, front 40.The parts that identical Reference numeral representative is identical also have identical functions.The pressurized stream of the pure washings of feeding in the jet pipe 41 ' in the venturi, however the washings that come from second unit 40 ' are used to feed first module 40.
The wire harness of rinsing is for example used the dilute solution of acetate then through in one and operation in unit 40 and 40 '.Neutralisation unit 40 " be quite analogous to rinse unit 40 ', equally also by jet pipe in the venturi 41 " running, the dilute solution pressurized stream of jet pipe feeding acetate in this venturi is in order to remove remaining alkali lye from wire harness 4.Unit 40 " in identical parts of the Reference numeral representative identical and have identical functions with unit 41 '.Neutralization solution below groove 42 " in be collected and be recycled utilization.The pH value of last acetum is at groove 42 " in determined, its component is controlled before recycle, with its pH value is carried out any possible correction and change in and trend.
In unit 40,40 ' rinsing and in unit 40 " in the wire harness 4 of neutralization then through a complete baking operation; for example in drying unit 60, this drying unit has along the coiling route of the outer surface of cylinder of the drier roll 62 of a succession of squeezing roll 61 and deep fat heating.As an alternative,, can be used to remove the liquid particle that still disperses with about 100 ℃ hot air dries by behind the venturi tube of 200 millibars of left and right sides low pressure.
According to acting on opposite operation with the front, the yarn 1 of the formation wire harness 4 after the mercerising is separated in wire harness 4 separative elements 70 then like this.
The first step be unwinding one or more when beginning around last boost line 5, it is wound up on one or more bobbins 71 again, bobbin is contained in one on the succinct former thereby rotation coil holder that do not illustrate in the drawings, rotate around wire harness 4 and according to the direction of the arrow B opposite, and have identical coiling yarn mouth with the arrow A direction.Yarn 1 becomes parallel again and no longer is collected in the wire harness, and they can be separated their and be wound up on the independent bobbin of yarn behind the mercerising by thread-carrier 72.
A mode that key property is the processed liquid infiltration of yarn of the present invention is actually the concrete situation that the mercerising of cellulose fibre is handled.The dipping in venturi tube 16 in the reactor 15 of beginning and the action time of reaction process are very short.In these devices, wire harness 4 is endowed higher flow velocity, and the yarn in the wire harness 4 equally also includes screw and violent spiral.As previously described, the mercerising processing can be repeated once in the subsequent reaction operation or several times, in order to accumulative effect, behind rinsing process, finish drafting process behind the result who obtains needs subsequently.
Fig. 2 has provided an alternate embodiment of reactor, and it has been made of the first of tubular filament Photoreactor 15 injector 16.In this changes, in the mercerising reactor 85 in the single venturi as described above jet pipe 16 by several, for example two or more, replace along the venturi tube of reactors in series, wire harness 4 is successively by them, from first venturi tube 86 ' to subsequently venturi tube 86 therein ", 86 " etc.Venturi tube drives liquid and also is made up of treatment fluid: be mercerising alkali lye in the present embodiment.In the embodiment that Fig. 2 describes, the inlet 87 of pressurised driving liquid is positioned at the side in the venturi tube 86, and wire harness 4 is with straight path axially-movable of jet pipe sequence in the venturi in the reactor 85.Pressurised driving liquid stream can be at inlet 87 ', 87 " ... locate to be segmented again, thereby from the beginning to finishing progressively to improve volumetric ratio of sequence, the i.e. long-pending and volumetric ratio between the yarn of axis direction processing of Wei Ru mercerising liquid.Processed yarn 4 is quilt break-in once more under the effect of break-in roller 9, enter and axially move from the axis direction of first venturi tube 86 ' along whole sequence, consistent with each contraction and the negative pressure direction of liquid contraction mouth, receive from 87 each several parts that arrive that enter the mouth and drive liquid stream.Therefore along the passage of yarn 4, the huge pulsation that can produce contact conditions, described contact conditions is flowing liquid speed and pressure around the wire harness 4 for example.In another alternate embodiment of the present invention, treat liquid first inlet 87 is corresponding with being used for, and has designed an inlet 88 that is used to connect the compressed air service, and it can be used for safeguarding, and the insertion of wire harness 4 drives in serial venturi tube 86.
Has jet pipe 86 in several venturis of series connection in this alternate embodiment of reactor 85, can allow the contact of liquid and sealing function more effective like this, this can be used to the mercerising reactor, also can be used for by alkali lye handle back yarn 4 rinsing and and technology in.
The amplification detail view of Fig. 2 shows an exemplary configurations of compensator 25, can regulate the tension force increase of wire harness 4 towards drafting system with this compensator.Compensator comprises two end wheels 91,91 ' that are positioned at expansion link 92 two ends, and the extreme position of expansion link is kept extended configuration by a built-in compressed spring 93.The higher tension force of wire harness 4 trends towards taking turns 91 and 91 ' the nearer and compression spring 93 that draws with two.For example, the low side of expansion link 92 is fixed on the equipment and high-end can freely the extension: therefore wheel 91 can freely do moving away from stationary wheel 91 ' direction.Two reference points 94 and 94 ' are positioned on the expansion link 92, and it represents recently and farthest fixing and adjustable limit of traverse of two wheels respectively, and it is by detecting near inductor 95 and 95 ' on two driver elements that are connected to device.
Arrived the nearest limit of setting when detector 95 detects reference point 94, or the compression limit of expansion link, tension force just risen to the maximum that can allow, and the driver element for the treatment of apparatus just turns round with the feeding rate of the wire harness 4 of a raising.Opposite, when detector 95 ' detects reference point 94 ' and has arrived the permission extension limit of the expansion link that allows, tension force reduces to the minimum of a value of permission, and then the driver element for the treatment of apparatus just reduces that the feeding of wire harness 4 is blunt to extend to a median to expansion link.When expansion link flexible remained in the setting range, the driver element of device remained unchanged in the feeding rate of wire harness is regulated.
According to the present invention, to the processed continuously technology of yarn, be mercerization recited above with treat liquid specifically, can obtain significant advantage with respect to known technology.Wherein Yi Xia characteristic should cause special attention.
According to the present invention, realize by continuous processing with the treatment process of treat liquid, do not need many batches yarn, in advance these batches yarn is made a yarn or reeled yarn, need be with tube yarn or reeled yarn unwinding and preparation again again after processing yet.
According to the present invention, continuous yarn is handled more economical, since the labour still less who uses, the high-performance of treat liquid and washings, investment of lower total factory and because finally still less the relevant environment expense that has reduced that the amount of reagent of discharging with waste water produces.The product quality homogeneity that continous processing system according to the present invention obtains has obtained significant raising, because the parameter of each road treatment process is more stable, they maintain desirable temperature, time, concentration value or the like.With regard to mercerising alkali lye, the amount of Treatment Solution is very little, and their carbonation reaction is appropriateness very.
