Description
Technical field
The present invention relates to be used for spinneret/spinning head, oiling device, manufacturing installation and the manufacture method of synthetic fiber.To describe the present invention in detail below.
At first, the present invention relates to a kind of be used to spin plurality of threads/filament and then when cutting apart, solidifying this long filament to its spinneret of reeling, and relate to a kind of manufacture method of using the synthetic fiber of this spinneret.More specifically, the present invention relates to a kind of spinneret that reduces the physical property difference between plurality of threads.
Secondly, the present invention relates to a kind of spinneret that is suitable for making polyurethane fiber, polyester fiber, polyamide fiber, polyamide fiber etc., and more specifically, relate to a kind of spinneret that can prolong the service life of filter medium and stably discharge polymer.
The 3rd, the present invention relates to a kind of device that comprises elastomer such as polyurethane that is used on clothes and the other products that is used to make, a kind of method that is used to make this elastomer and a kind of oiling device of refueling to by continuous spun elastic filament of being used for.
Background technology
The device for spinning that is used for synthetic fiber has a spinneret that is used for polymer is carried out spinning usually, and one is used for the oiling device and that refuels from the spun long filament of the spinneret orifice of this spinneret be used for reeling after the oiling roller that batches of this long filament.
Up to now, device for spinning various improvement have been made so that can stably produce high-quality long filament.Yet, as described below, what time need in addition to improve at building block and aspect being provided with.
Spinneret
Therein polymer from a spinneret, discharge and the manufacturing of the synthetic fiber of when solidifying, being reeled in, use a kind of following method usually.That is,, discharge polymer and winding several threads then from a plurality of spinnerets of every spinning machine from the viewpoint of productivity ratio.
Traditionally, in order to simplify its operation, maintenance etc., the spinneret that is used for this device for spinning have be arranged to arrange for example circumference, rhombus layout, grid layout, interlaced arrangement etc. more spinneret orifice to be mainly used in the effective use that realizes this spinneret area.
Yet in this employed up to now spinneret, variations in temperature is very big between the position of spinneret orifice.In addition, because polymer is to discharge from many rows, so blow to the cooling conditions of air difference on the long filament of being discharged.These factors have increased the differences of physical properties between long filament, and this is a problem.
Especially, during melt spinning, spin a kind of fusion elastomer with extremely low spinning tension.Therefore, for example can not cause that at common melt spinning the variation of state that is used to cool off a long filament of discharging of any problem can influence the fusion elastomer significantly in the polyester spinning etc., and cause it inhomogeneous, thereby make its deterioration.
In addition, in this spinneret, usually by before molten polymer is discharged from spinneret orifice, this molten polymer being filtered by a kind of filter medium with foreign matter/contaminant removal.In a kind of like this melt spinning is handled,, be known that by using a kind of being provided with as letter in Figure 13 shown in to filter from aspects such as processing ease, simplified equipment.Promptly, placing tight the place ahead of an assembly 102 spinnerets 101 to make a filter medium 100 has a space so that this polymer passes through the whole surface of this filter medium equably between this filter medium 100 and spinneret 101, thus the whole surface that can use filter medium 100 effectively.
Yet in melt spinning, it is usually higher and pollutant will be deposited on the filter medium 100 during operation gradually to be applied to pressure on the filter medium 100.As a result, the pressure that is applied on the filter medium 100 raises, and as shown in figure 14, the distortion of the whole or part building block of filter medium 100.This can cause irregular flow in the intake section of the spinneret orifice 103 of spinneret 101, and, in some cases, spinneret orifice 103 half obstruction that can become.A kind of like this state can cause the rapid rising of filter pressure, the decline and irregular the flowing of filter efficiency, and this can cause negative effect to the long filament of discharging from spinneret orifice, causes incomplete discharge etc.Therefore, when the some parts of filter medium was out of shape, even this filter medium itself still can filter, this whole filter medium should be changed immediately, thereby caused productivity ratio to reduce.Especially, compare with filter medium when having less discharge area when spinneret, for example be used for the spinneret of monofilament, this problem is very obvious.
Oiling device
Be used for the device for spinning of synthetic fiber, a kind of oiling device refuels to prevent because the wearing and tearing grade causes the damage of this long filament to long filament, and increases its smoothness and make processing ease.
A kind of such oiling device is a roller formula oiling device, wherein, one roller under being immersed in state in one oil groove/fuel tank, is rotated its some parts, on the surface of this roller, applying a uniform oil reservoir, and make long filament with this roller surperficial attached in advance and apply to carry out oil.
Also have a kind of guiding oiling device, wherein oil is supplied in the groove that is formed in the guiding piece, and a long filament is introduced this groove and it is advanced, thereby on this long filament, refuel.
In these oiling devices, before this long filament is wound on the roller, this long filament that is discharged from when oil is applied on this long filament or this not long ago contacted with the surface of described guiding piece.
The long filament that is discharged from refuel and contact surface on part because it solidifies etc. fully instability extremely.Therefore, any fluctuation of frictional resistance can be strengthened the labile state of this long filament, and this can to the character of the long filament of reeling particularly its homogeney have a negative impact.
In order to address the above problem, the inventor proposes a kind of oiling device that comprises at least one induction element, this induction element is used for by making a long filament will be applied to this long filament by an oil that is formed on the fuel feeding opening supply of this groove by a groove, wherein, this groove has: a summit, this summit have a tangent line on (this long filament) vertical curve/vertical line; All from this summit with respect to sweptback upper inclined surface of (this long filament) vertical line and inclined-plane, a bottom, simultaneously, this groove has the narrowest part with summit position adjacent place.This fuel feeding opening is arranged in above the summit 3mm or higher and be formed at this from (this long filament) vertical curve 2mm or farther position rooved face is arranged one, and has a bigger diameter (the open No.1993-23076 of Japanese unexamined patent publication No.) of width than the narrowest part of this groove.
Disclosed oiling device is an outstanding invention in the open No.1993-230706 of this Japanese unexamined patent publication No., wherein, is carrying out fuel feeding by when making that contact area between this long filament and guiding piece is as far as possible little and reduce to rub.
In recent years, to the increase in demand of elastomer, but because they can realize surcharge by increasing elasticity, improvement adaptability (fitting ability) etc.Elastomer for example as a kind of polyurethane elastomeric fiber of exemplary, shows the high extensibility of 50-300% in the actual scope of application.The long filament of one elastomer spins from a spinneret orifice and by air drying, spinning oil is applied thereto to reduce the friction between this long filament and guiding piece etc. then.Consider its high extensibility, compare, apply about 10 times oil mass with general fibre.
Yet, in the open No.1993-230706 of above-mentioned Japanese unexamined patent publication No. in the disclosed oiling device, even it is described a large amount of when oily when planning on an elastic filament, to apply, if this elastic filament does not contact consistently with this oiling device, promptly, if it, also will occur the part of fully not refueled because spinning swing, vibration or other factors and from oiling device or even temporarily break away from this elastic filament, thereby reduce the performance of this elastomer significantly.
The layout of device for spinning
As mentioned above, in recent years, polyurethane elastomeric fiber is owing to its excellent elasticity causes a large amount of attentions.Polyurethane fiber can be used for various purposes, but thereby because it can increase elasticity, improvement adaptability, stable shaped etc. make the dress material increment by the less amount of only mixing in dress material.
As the manufacture method of polyurethane elastomeric fiber, known have dried spin processes, wet spin processes and a melt spinning method.Wherein, the polyurethane elastomeric fiber that obtains by melt spinning method has good thermosetting, erosion resistant degree and transparency and low production cost.Therefore, in recent years, the use amount of polyurethane elastomeric fiber increases.In melt spinning method, as mentioned above, molten polymer is discharged from a spinneret, and the long filament of this discharge solidifies by cooling air (cold wind), and is refueled, and is wound on then on the roller.
The coiling of elastic filament normally carries out in the mode identical with the polyester filament with low elasticity, Tynex etc.Especially, molten polymer is expressed in the spinneret from an extruder (not shown), and from each spinneret orifice the long filament of elastomer is discharged along substantially straight down a direction.Each long filament of elastomer blows and solidifies on it by will cool off air with a hair-dryer, and refuels by an oiling device, and platoon leader's silk turns to by an induction element.After this, regulate the tension force of this elastomer of arranging again, and this long filament is fed to a work beam and is wound into the silk volume by two godet rollers.
In above-mentioned manufacturing installation, reeled in distortion with the state of 90 ℃ of its orientation rotations from the spun elastic filament of spinneret.Therefore, the length in this long filament road and dissimilate in this elastic filament from the frictional force that guiding piece is subjected to.Therefore an impossible problem when reel above-mentioned polyester, nylon etc. has appearred.That is, because polyurethane elastomeric fiber becomes than easier strains such as polyester, when this polyurethane elastomeric fiber was reeled with different long filament road length and frictional force, the performance of this elastomer in each volume dissimilated, and causes product performance to alter a great deal.For example, be arranged in the silk volume of work beam central authorities, almost do not having to twist and reel from the spun elastomer of spinneret.On the other hand, being arranged in the silk volume of work beam one end, reel with the bigger twist angle of variation that causes by guiding piece from the spun elastomer of spinneret.Therefore, owing to the frictional resistance that contacts this long filament that produces of long filament and guiding piece becomes bigger, and between a plurality of volumes, produce the tension difference of this elastic filament.Especially, in the silk volume of end, because the length in elastic filament road is longer, this elastic filament stands bigger air drag.This has further increased the tension difference between end silk volume and the central authorities' elastic filament of rolling up.
The difference of the frictional force that each elastic filament is subjected to causes the shape of thickness, elasticity, intensity and the undrawn yarn volume of long filament to produce difference.If by making fabric in conjunction with the silk volume that is wound with long filament of different nature on it, then the value of this product will be owing to as reducing by the bad outward appearance as shown in the striped etc.
Summary of the invention
The invention provides following invention to solve the problems referred to above of prior art.
Spinneret
First purpose of the present invention is to provide a kind of can be controlled at the spinneret of the physical property difference between long filament from their temperature differences when they are cooled spinneret orifice by what minimize the plurality of threads of discharging from spinning machine as far as possible.
First purpose of the present invention can be by a spinneret realization that is used to make plurality of threads, and this spinneret comprises a plurality of spinneret orifices that are formed in the single spinning plate, and wherein, described spinneret orifice is set to become substantially delegation.
A plurality of spinneret orifices of formation and spinneret orifice are set to become substantially delegation can reduce the spinneret surface temperature change in a single spinning plate of spinneret.Simultaneously, in cooling during from long filament that spinneret orifice is discharged, be set to become substantially delegation by spinneret orifice, can avoid fully, and the cold wind that blows on the long filament that moves ahead does not influence the long filament of going in the back owing to the temperature of cooling off the cold wind that causes at the spun long filament that moves ahead raises.When satisfying these conditions, can make uniform long filament and do not have the variation of the state of cooling.
Preferably, in spinneret of the present invention, be formed with 8 or more a plurality of spinneret orifice.This is because in the field of a large amount of spinneret orifice of needs, that is, in the large-duty field of needs, effect of the present invention can easily show by having 8 or more a plurality of spinneret orifice.
In addition, preferably, cold wind blows from a direction that is basically perpendicular to the polymer of discharging from above-mentioned spinneret with spinneret orifice of being arranged to delegation.This is because by blowing cold wind in such a way, the temperature of the cold wind of being accepted by each long filament becomes evenly, and the temperature of spinneret becomes even in above-mentioned direction.This has reduced the temperature difference between spinneret orifice.
The present invention preferably is applied to make the fusion elastomer, and this is because its effect is remarkable especially.Compare with multiduty fibers such as polyester fiber, polyamide fibers, elastomer has extremely low spinning tension usually.The temperature and being used to that its physical property is subjected to spinneret is cooled off the very big influence of temperature of the air of the long filament of discharging from spinneret orifice.Therefore, in elastomer, not only between long filament, show tangible differences of physical properties, and the swing of the long filament in cooling segment is also different because of long filament, and causes the inhomogeneous of long filament and fracture.
It is an essential characteristic of the present invention that spinneret orifice is set to become substantially delegation.In this was provided with, it was at interval necessary to consider that being used between spinneret orifice is easy to the long filament separate operation, and preferably the long filament number is 1 to 3.
Second purpose of the present invention is to provide a kind of spinneret, thereby this spinneret can the filter capacity that be arranged on the filter medium in this spinneret prevents from not exclusively to discharge and the replacement cycle of prolongation filter medium boosts productivity by making full use of.
Consider that filter efficiency can descend when contact when filter medium distortion and with spinneret, the inventor has carried out a large amount of research solving prior art problems, and so and finishes the present invention.
In order to realize above-mentioned second purpose, the invention provides a kind of spinneret, wherein, be provided with one on the top of this spinneret and be used for removing the filter medium of foreign matter, and be formed with and be used to guide through the molten polymer of filter medium guiding groove to spinneret orifice from molten polymer.
By being provided for guiding the guiding groove of the molten polymer of process filter medium to spinneret, even filter medium is out of shape and contacts with spinneret, also can be so that polymer passes through the surface of the filter medium directly over this groove reliably at least.This is arranged so that and can effectively utilizes filter area, and with replacement cycle of filter medium extend to one very long during and can not cause incomplete discharge.
Preferably, of the present invention be used to guide through molten polymer to the groove of spinneret orifice of filter medium arrange radially and be its center with spinneret orifice.This is because a kind of like this polymer that can guide the process filter medium reposefully that is arranged so that is to spinneret orifice.
In addition, when spinneret has a spinneret orifice corresponding to a filter medium, can realize effect of the present invention significantly.In other words, for example be used for the spinneret of monofilament, the area of the inlet in the top of spinneret orifice with respect to the area of filtration members hour, effect of the present invention can display significantly.
Consider the design difference of the size of spinneret, the intensity of filter medium etc., the shape of above-mentioned groove, the degree of depth etc. are unrestricted.Yet polymer should be directed in the spinneret orifice.Having above-mentioned other setting in addition causes polymer can not pass through filter medium.Preferably, the groove of spinneret is arranged on the whole surface of filter medium, and the distance between groove is less, and the number of groove is more.This is because if the distance between groove is excessive, this groove can be owing to the distortion of filter medium is stopped up.In addition, if groove forms inhomogeneously or the number of groove seldom, then can not utilize the filter capacity of filter medium fully or can not discharge stably.
Can be owing to the protuberance that groove forms is set with an acute angle towards filter medium.This makes and can reduce area that groove contacts with filter medium and the intensity that keeps protuberance, feasiblely can use filter medium effectively.
By being set in spinneret, protuberance that groove forms can begin to contact when filter medium is set with this filter medium.Even under this state, also can realize the effect of spinneret of the present invention.
Preferably, spinneret of the present invention can be used to spin for example elastic filament of typical polyurethane filament.With multiduty long filament for example polyester, polyamide etc. compare, elastic filament often is subjected to the uneven influence of long filament that causes because of disturbance, and therefore effect of the present invention becomes remarkable.

Illustrate according to an embodiment who is used for the oiling device of elastomer of the present invention below with reference to Fig. 5 to 9.
In Fig. 5 and 6, with reference to label 31 expressions one oiling device, with reference to label 32 expressions one nozzle block, with reference to label 33 and 33 ' expression godet roller, reference marks F represents friction roller, and reference marks P represents paper tube.In Fig. 6, with reference to label 34 expression gear pumps, with reference to label 35 expression extruders, with reference to label 36 expression hair-dryers.The elastic filament W that discharges from nozzle block 32 through oiling device 31, godet roller 33,33 ' and friction roller F be wound on the paper tube P.
Oiling device 31 comprises that one is used for oil is added to the guiding piece 39 that the element 38 and that oils on the elastic filament W is used for elastic filament W is guided to the element 38 that oils.This elastic filament W one guiding device is made of oil element 38 and guiding piece 39.
Shown in Fig. 7 and 8, the element 38 that oils comprises that a slot part 40 that is used for guiding elastic filament W and one are towards the opening 41 that is formed at this slot part 40 oil supplying hole 42 of opening to be used for refueling to the elastic filament W that advances at slot part 40 communicatively.This slot part 40 comprise one with Fig. 7 in vertically the apex portion that contact of dotted line H 43, one with respect to the vertical curve H from these apex portion 43 extensions have the upper inclined surface 44 of back rake angle and lower bevel 43 and with the narrowest part 46 of these apex portion 43 adjacent position.
Preferably, this apex portion 43 be circle and have a little radius (for example, 0.1 to 20mm); But, to the not restriction of its shape.Importantly elastic filament W only contacts with slot part in this apex portion 43.Therefore, to upper inclined surface 44 and lower bevel 43 without limits with respect to the back rake angle α of the vertical curve H that extends from this apex portion 43 and β, but preferably this angle in 15 ° to 70 ° scopes.
As shown in Figure 7, preferably, the opening 41 in this slot part 40 is provided with in such a way, promptly, 41 beeline dH is 3mm or bigger from apex portion 43 to opening, is positioned at the direct of travel top of elastomer, and is 2mm or bigger from the beeline L of vertical dotted line H.Notice that above-mentioned " vertical curve " is the term that is used to limit oiling device of the present invention, and in the spinning of reality, this elastic filament can enter from (between α and β) between upper inclined surface 44 (lower bevel 45) and this vertical curve.
In addition, preferably, the maximum gauge of opening 41 is greater than the narrowest width (N among Fig. 8) of slot part 40.It is one trapezoidal that this slot part 40 can form its side-looking section, as shown in Figure 7, and as shown in Figure 8, when when the front is seen, this have slot part form can one from upward to narrowing down to the angled V-arrangement of the narrowest part adjacent with apex portion 43, and broaden with an inverted V-shaped angled towards the below.The sidewall of this slot part 40 forms a groove toward each other and with upper inclined surface and lower bevel; Yet this slot part 40 can have a flexure plane shape that does not have tangible sidewall.
Preferably, the width N of the narrowest part 46 of this slot part 40 is 0.1 to 1.5mm.This is because if the width N of the narrowest part 46 of this slot part 40 greater than 1.5mm, will be difficult to prevent the swing of the long filament in this slot part 40, and oiling tends to become inhomogeneous.In addition, preferably, this slot part 40 to the depth D of apex portion 43 is 3 to 10mm.Note, preferably, the maximum gauge of opening 41 than the minimum widith N big 0.2 of the narrowest part 46 of slot part 40 to 0.4mm.
The element 38 that oils with said structure remains on spun elastic filament and prevents in the groove that change in location from being reeled until them, and has reduced significantly owing to following the labile state that the into friction variation in holding point of direction (along the vertical curve direction of this elastomer) causes.
Guiding piece 39 can constitute: for example, as shown in Figure 9, along a direction that is parallel to elastic filament two pectinate plates 39 ', 39 ' are being set, and this elastic filament is by the gap between this broach.
Guiding piece 39 must be arranged to: the part of this elastic filament below the apex portion 43 of element 38 that oils has one greater than 0 ° and be not more than 3 ° back rake angle ε (see figure 7) with respect to the vertical dotted line H that draws from apex portion 43, and more preferably is a back rake angle ε who is not more than 2 °.As long as satisfy this requirement, without limits to shape of guiding piece 39 etc.
Preferably, owing to following reason, around the apex portion of the element 38 that oils and the surface roughness of guiding piece 39 be 2 to 10S.If this surface roughness is less than 2S, it is big that real contact area becomes, and friction becomes big.On the other hand, excessive if surface roughness becomes, it is big that capillary variation becomes, and keep the ability of oil to change easily.If surface roughness surpasses 10S, what tend to refuel is inhomogeneous.
In addition, this oiling device of the present invention is preferably used for elastomer, and wherein the long filament number is 2 or still less, and its overall fineness is 88dtex or littler.This be because if the long filament number greater than 2, the boundling state between long filament can change, and almost can not obtain effect of the present invention.When total fineness surpassed 88dtex, the part of not refueling appearred in a circumferential direction easily.When such part contacted with induction element, this long filament partly was subjected to excessive frictional resistance.
Table 3 and 4 shows the evaluation result of the melt spinning device with above-mentioned oiling device.
Table 3 shows the measurement result with the tension force of advancing of the long filament of 200% elongation of reeling when changing back rake angle ε.Table 4 shows the defective incidence of measuring in rolled long filament (cheese), promptly so-called step incidence (step-occurrence rate) when changing back rake angle ε.Be used for measuring the test of tension force of advancing, the feed speed of elastomer is set at 15.7 meters/minute, and Measuring Time is set at 1 minute, and the time set that is used to import data is 0.2 second/time.In table 3 and 4, A to L is corresponding to 12 cheeses (be cheese-form and be wound on elastic filament on the work beam).

As clearly shown in Figure 3, reach 3 ° up to back rake angle ε, the tension force of advancing does not all almost change; Yet, when back rake angle ε becomes 4 ° or when bigger, it changes and becomes greatly.
Equally as clearly shown in Figure 4, when back rake angle ε surpasses 2 °, step (a kind of defective of the cheese of coiling) appears, and along with this stage incidence of increase of this back rake angle ε becomes big.According to table 4, back rake angle ε preferably is not more than 2 °; Yet what need only this back rake angle ε is not more than 3 °, just falls within the allowed band of practical operation.
Shown in clear in Fig. 3 and 4, according to above-mentioned evaluation test, oiling device of the present invention can be by using induction element to set for back rake angle ε greater than 0 ° and being not more than 3 ° of maximum and the difference between the minimum of a value and stage defectives that reduce the tension force of advancing.As a result, oiling device of the present invention can keep the elastic filament quality by spun elastic filament is contacted with guiding device so that oil is applied on the long filament, and prevents simultaneously because the frictional force that contact produces becomes excessive.
Then, a kind of below with reference to Fig. 2 and 10 explanations according to the device that is used to make elastomer of the present invention.
In the present embodiment, with a kind of melt spinning device that is used to make polyurethane elastomeric fiber of explanation.
Importantly, as shown in Figure 2, in this melt spinning device 4, a kind of spinneret 3 that is used to spin elastic filament W is arranged to extend along the direction of the axial direction that is basically parallel to a work beam 12, and the spinneret orifice 2 that is used to discharge elastic filament W is at regular intervals along the setting that vertically is in line of spinneret 3.
One is used for molten polymer and its extruder 5 that is extruded into spinneret 3 is passed through gear pump 6 being connected with spinneret 3.Almost under spinneret 3, be provided with a plurality of being used for elastic filament W is arranged to the induction element that waves 59 that is parallel to the alignment direction of spinneret orifice 2 and controls this long filament.As shown in Figure 10, the direction of the parallel longitudinal of induction element 59 edges and spinneret 3 is arranged on and makes on the supporting member 51 that the interval between the induction element 59 is bigger than the interval between the spinneret orifice 2.Thereby each elastic filament W is being reeled in the longitudinal extension of spinneret 3.Notice that it is 1.5 ° or littler with respect to maximum and the difference between the minimum of a value of the inclination angle λ of vertical curve that the distance between each induction element 59 is arranged to each elastic filament W.
In each induction element 59, be formed with the slot part 53 that an elastic filament W engages therein, and, in slot part 53 with the contacted part of elastic filament W in be formed with a jet pipe 55 that is used to discharge oil.In each jet pipe 55, as shown in Figure 2, oil is supplied with through a gear pump 57 from a fuel tank 59.In addition, the direction of exerting pressure that each jet pipe 55 is configured to continue to use in the induction element 59 that elastomer is tilted refuels to elastic filament W, and reason is as described below.Because each elastic filament W has a down dip and expansion downwards in the effect of induction element 59, be applied to that thread-tension on this long filament works so that this long filament returns towards the central authorities of supporting member 51, and this has increased the friction between induction element 59 and elastic filament in the direction.As mentioned above, discharge oil towards elastic filament W, can increase the effect of the friction of reduction and induction element 59 by direction of exerting pressure along induction element 59.Notice that in the present embodiment, oiling device of the present invention is made of a jet pipe 55, gear pump 57 and fuel tank 59.
As shown in Figure 2, be provided with a hair-dryer 7 between spinneret 3 and induction element 59, this hair-dryer blows cold wind along the direction vertical with the alignment direction of elastic filament W on elastic filament W.Below this induction element 59, be provided with 9,10 and work beams 12 of two godet rollers.They are arranged to the edge and extend with the direction of the parallel longitudinal of spinneret 3.With on winding filament to the silk volume 60 be by one in this long filament of guiding the lateral guides (not shown) along the axially reciprocating of this volume 60 carry out.
Below, a kind of use of explanation is had the elastic filament manufacture method of the device for spinning of above-mentioned setting.Polymer by an extruder 5 fusions is extruded to spinneret 3 by a gear pump 6 when its quantity delivered is conditioned, and spins elastic filament W downwards by spinneret orifice 2.This elastic filament W extends the distance of also expanding a little simultaneously therebetween along downward direction.After being refueled by an induction element 59, this elastic filament is being wound onto on two godet rollers 9,10 when the direction identical with the alignment direction of spinneret orifice 2 alignd.Then, after regulating its tension force by this godet roller 9,10, this elastic filament W delivers to a work beam 12, and is wound on the silk volume 60.
As mentioned above, according to present embodiment, because the alignment direction of the spinneret orifice 2 of spinneret 3 is arranged to be basically parallel to the axial of godet roller 9,10 and work beam 12, elastic filament W is wound onto on the work beam 12 with the alignment direction identical with the alignment direction of spinneret orifice 2, and can not make this row elastic filament produce deflection largely.Therefore, thus can reduce owing to the difference that acts on friction on the elastic filament and the tension force between elastic filament that the difference of each long filament road length causes after making this row elastic filament deflection and reduce therebetween differences of physical properties.Therefore, even when the silk volume that uses at the diverse location place of same device, also can prevent from striped etc. on cloth, to occur, thereby high-quality product is provided.
In addition, as shown in Figure 10, each elastic filament W is 1.5 ° or littler with respect to maximum and the difference between the minimum of a value of the inclination angle λ of induction element 59.This makes and can further reduce the difference of the frictional force that produces between elastic filament and make the physical property homogenising of respectively rolling up long filament between elastic filament W and induction element 59.
In the above-described embodiments, in induction element 59, refuel; Yet this oiling device can be arranged with this induction element in 59 minutes.As an oiling device, for example, can use a kind of wherein elastic filament be configured to its surface on be applied with the type that contacts of roller of oil.Yet, importantly this long filament with refuel before induction element 59 contacts, that is, refuel in the somewhere between spinneret orifice 2 and induction element 5.Thereby, can prevent from that elastic filament from not refueled and having under the state of a bigger coefficient of friction at it to contact with induction element 59.This has prevented that elastic filament is directed element and tangles and be damaged.
To the structure of this induction element without limits, as long as it can control waving of long filament, and therefore, except an induction element is provided for an elastic filament, can also be arranged to: for example, a plurality of grooves of formation and each groove guide an elastic filament in supporting member, or the like.
In the above-described embodiments, device for spinning of the present invention is used for making a kind of elastic polyurethane long filament by melt spinning; Yet this device can be used for other method, for example dry spinning and wet type spinning.
Can also use this device to make above-mentioned elastic polyurethane long filament elastic filament in addition.
The following describes example of the present invention and comparative examples about above-mentioned elastomer manufacturing installation.In example 5, use shown in Fig. 2 and 10 device and in comparative examples 9, use the device shown in Figure 11 and 12.
Device for spinning 81 shown in Figure 11 and 12 comprises that one has that a plurality of vertically the spinneret 3, one of the spinneret orifice 2 of alignment are used for being arranged on hair-dryer 7, the godet roller 9,10 between spinneret 3 and the oiling device 8 and being used for elastic filament W is wound to a work beam 69 on the volume 67 the oiling device that refuels 8, one along it in the downward direction guiding elastic filament W of spinneret 3.Aspect this, this device for spinning 81 has the identical structure of device as shown in Figure 2.Yet, the difference of its structure and device shown in Figure 2 be a guided rings 82, godet roller 9,10 and work beam 12 be configured to below the oiling device 8 its axially with spinneret 3 vertical between angle be 90 ° to utilize the space fully.
In device for spinning 81, make the elastic polyurethane long filament in the following manner with said structure.Molten polymer is extruded into spinneret 3 from an extruder (not shown), and elastic filament W discharges along direction substantially straight down from spinneret orifice 2.Each elastic filament W is by being blown cold wind cooling on it to be cured by hair-dryer 7, oil is applied on each elastic filament by oiling device 8, and this row elastic filament W turns to by guided rings 82.Its alignment direction therefore and the tension force of the elastic filament W of distortion is regulated by two godet rollers 9,10, this long filament is sent on the work beam 12 and is wound on the silk volume 60 then.
In above-mentioned example 5 and comparative examples 9, the diameter of spinneret orifice is set at 0.28mm, and spinning speed is set at 550m/min, and the resin melt temperature is set at 200 ℃, and this long filament is wound on 12 silk volumes.
Table 5 is illustrated in the stress ST value of the elastic polyurethane long filament in example 5 and the comparative examples 9.This stress ST value is the tension force of advancing of the elastic filament of the elongation 200% of reeling in the above described manner when with the supply of the speed of 15.7m/min.
