Description
Technical field
The present invention relates to utilize in the crush cutting operation tow to cut off machineries such as sett frame, Yi Bian be applied in the tension force of regulation, Yi Bian become the fiber of sliver, the manufacturing installation and the manufacture method thereof of this fiber by crush cutting.
Background technology
In general, fiber is in spinning process, with fusion or the polymer that dissolved from nozzle spit into the solution, in the air or carry out spinning in the inert gas, fiber after the spinning is pulled roller traction, afterwards, gives the aqueous solution of surfactant or finish etc., making its boundling by the batching licker-in is specific fibre bundle (tow, fibre bundle) batches the time, and be accommodated in the accommodating container, carry out batch processing.Treated like this fibre bundle from the debatching of batching licker-in or be drawn out from accommodating container, is sent in the stretching process or curling operation as the dyeing and finishing treatment process, makes the fibre bundle as goods.
Produced like this fibre bundle utilizes 2 kinds of manufacture methods to be manufactured into sliver (aggregate of staple fibre, the precursor of short fibre yarn).A kind of manufacture method is the method that is fabricated to sliver with the staple fibre (staple fibre) that machineries such as carding machine form the cut staple bundle, another kind of manufacture method is to utilize tow to cut off when machinery (tow to yarn machine) such as sett frame applies the tension force of regulation to fibre bundle to carry out crush cutting, thus the method for manufacturing sliver.
Using tow to cut off in the crush cutting operation of machineries such as sett frame, if the local fiber footpath portion of existence becomes the position than minor diameter on the fiber axis direction of fiber, then in directly slivering was handled, stress concentrated on this position, caused carrying out in the crush cutting of the near zone at this position.
Therefore, if the above-mentioned position that becomes path exists in fibre bundle at random, the shearing length of being undertaken by crush cutting becomes irregular, produces the sliver from short shearing length to long shearing length.At this moment, if watch the distribution of the fibre length that obtains according to the fibre length Pareto diagram, shearing length is distributed in widely in the length range as can be known.If the fiber from the fiber of short shearing length to long shearing length mixes at random, not only become the occurrence cause of the fault in the spinning process thereafter, also can become the big problem that causes shrinking spinning such as generations correlation of attributes with the fiber that long shearing length takes place.
Therefore, in spinning process, do not become partly than this fibre bundle in the position of minor diameter, thought the whole bag of tricks for fibre diameter does not take place on the fiber axis direction that is manufactured on fiber.On the fiber axis direction of fibre bundle, fibre diameter becomes the position than minor diameter partly, can think because the fiber that spues from nozzle or the hauling speed of fibre bundle are changed, cause changing with respect to the elongation of fiber stress in the spinning, local path position takes place in the superficial layer of fiber or fibre bundle as a result.
Generation for the path position that prevents the part on the fiber axis direction, usually will become constant with respect to the hauling speed of fiber that spues from nozzle or fibre bundle, or lubricated the becoming along sliding between guide member such as cord roller and fiber or the fibre bundle, make simultaneously lubricatedly can not produce change.
In addition, even under the situation of the fibre bundle of the generation of using the path position controlled the part on the fiber axis direction, when in the crush cutting operation, carrying out the crush cutting processing, still there is the problem that the cut-out of shearing length in the scope of predefined regulation shearing length is difficult to.
That is,, be not limited to usually be cut off, produced error by the shearing length of crush cutting in the position of regulation even when machineries such as utilizing tow cut-out sett frame applies regulation tension force to fibre bundle, carry out crush cutting.As long as see the distribution of the shearing length on the shearing length Pareto diagram at this moment, just know that this distribution is dispersed in the wide scope.
Therefore, when applying regulation tension force, machineries such as utilizing tow cut-out sett frame carries out crush cutting even need exploitation, on shearing length, do not produce error yet, and watch according to the shearing length Pareto diagram obtain by the distribution of the shearing length of crush cutting the time, its distribution may be limited to fiber, the manufacturing installation of making this fiber and the manufacture method thereof in the narrow range.
Summary of the invention
The objective of the invention is to, provide a kind of and utilize the shearing length in the shearing length Pareto diagram that tow cuts off the sliver that carries out crush cutting when machinery such as sett frame applies regulation tension force to distribute, may be limited to narrow range interior fiber, the manufacturing installation of making this fiber and manufacture method thereof.
The objective of the invention is to realize by following each invention.
Promptly, first scheme of the present invention is a kind of fiber, it is characterized in that, this fiber roughly equally spaced has the less fiber footpath portion of diameter along the fiber axis direction, fibre diameter in this less fiber footpath portion is setting diameter-5%～-40% of this fiber, above-mentioned roughly equally spaced length be with the crush cutting operation in maybe will be extended by predefined shearing length length about equally and estimate in interior length.
In this is invented, to handle if use fiber to carry out crush cutting with above-mentioned formation, the shearing length distribution that can obtain in the shearing length Pareto diagram can be limited in the interior sliver of narrow range.
That is in the crush cutting operation, be that the fiber footpath portion that roughly equally spaced forms on the fiber axis direction is that the position of path is that the zone at center cuts off.And, because interval at interval about equally, maybe will extend estimation in interior length as the length that should cut off in the crush cutting operation, become and predefined shearing length length about equally for wanting cut each fiber, therefore, in the crush cutting operation, want cut length can become the length that satisfies the predefined shearing length of fiber.
In addition, fiber footpath portion becomes the diameter at path position, with respect to the setting diameter of fiber used herein, and must be in-5%～-40% scope.If less than-5%, it is more difficult that the stress that is caused by tractive force in the crush cutting operation as path is concentrated with respect to the setting diameter of fiber for the diameter at path position, then carry out in that the cut-out at this path position is more difficult.In addition, if the diameter at path position with respect to the setting diameter of fiber greater than-40%, the situation of fiber beam cutting then will take place in the postprocessing working procedures such as the stretching after spinning, heat treatment.
Alternative plan of the present invention is a kind of fiber, it is characterized in that, this fiber by the cut effective shearing length of crush cutting operation 70% or more than, be maybe will be extended by predefined shearing length in the crush cutting operation to estimate in about 70%～130% of interior length.

To pass through guide member, counter-rotating roller by the fiber that wet type spinning or dry spinning spue from nozzle, with the traction roller traction of constant-speed drive.At this moment, by making the peripheral speed cyclical movement of the counter-rotating roller that is configured between nozzle and the traction roller, can be so that the tensile stress change between the tensile stress between guide member and the counter-rotating roller and counter-rotating roller and the traction roller.Because tensile stress periodically raises,, can periodically form the position that fiber footpath portion becomes path for being between guide member and the counter-rotating roller and the fiber between counter-rotating roller and the traction roller.
And, the relation of the cycle of the counter-rotating roller by the adjustment cycle change and the speed of travel of fiber or fibre bundle, and the distance between guide member and the counter-rotating roller, the interval that fiber footpath portion can be become path is adjusted into the length of predefined shearing length in the crush cutting operation maybe will extend estimation in interior length length about equally.Thus, can estimate to form the position that fiber directly becomes path continuously maybe will extend with the length of predefined shearing length at interior length interval about equally.
The manufacturing installation of the fiber that the invention of the cubic case of the present invention relates to is on the basis of the 3rd scheme, limits the counter-rotating roller and has along the shape of its circumferencial direction periodically deforming.
In this invention, the peripheral shape of counter-rotating roller is the shape of periodically deforming, the roller of the shape by will having the peripheral shape periodically deforming uses as the counter-rotating roller, can roughly equally spaced form the position that fiber directly becomes path on the fiber that spues from nozzle.
As the counter-rotating roller, also can use the rotating shaft eccentric roller different with the shaft position of traction roller, can also use the roller of the periphery of counter-rotating roller as cam face.In addition, also can use the roller that has formed jut on the outer peripheral face of roller.As above-mentioned jut, can be the jut that is fixed on the roller outer peripheral face, also can constitute the protuberance of giving prominence to from the outer peripheral face of roller with freely haunting.When jut freely haunts, can utilize controlling organization to control with respect to haunting of jut.
The manufacturing installation of the fiber of the present invention's the 5th scheme is to limit to have the control device that the peripheral speed of above-mentioned counter-rotating roller is controlled in cyclical movement on the basis of the 3rd scheme.

The specific embodiment
Below specifically describe the preferred embodiments of the invention with reference to the accompanying drawings.The present invention as make fusion or the dissolving after polymer spue from nozzle dry type or wet type, thereby carry out the fiber of spinning, the manufacturing installation and the manufacture method thereof of this fiber, can be suitable for effectively.In addition, though being example, the fiber that forms with the wet type spinning in the present embodiment describes, but the present invention is not limited to the made fiber of damp process, no matter be dry type or wet type, so long as synthetic fiber just can be suitable for, also comprise the technical scope that those skilled in the art can be suitable for easily certainly.
What represent among Fig. 1 is the schematic diagram of spinning process of the present invention.In spinning process, the Polymer Solution or the solution that obtain by fusion or dissolving, spued by the nozzle 2 that possesses a plurality of pores (hole) in solution, yarn guiding chase comb 4, counter-rotating roller 3 through as guide member are pulled by the traction roller 6 that drives with the constant speed rotation.Traction roller 6 is driven engine 7 and drives with the constant speed rotation.
In spinning process, the fiber 1 that spues from a plurality of nozzles 2 is pulled roller 6 tractions, and then, subsequent processing not shown in figure moves.In addition, guide member is not limited to yarn guiding chase comb 4, can also use free roller or be guide plate of curve form etc. with the sliding contacting part of fiber.
Like this, be in the fiber 1 that periodically increases the tensile stress state, by the tensile stress that has increased, its fiber footpath portion is reduced, forms the position of path.Particularly, when the position of the path that forms between counter-rotating roller 3 and the yarn guiding chase comb 4 is come between counter-rotating roller 3 and the traction roller 6, because the increase of the tensile stress between counter-rotating roller 3 and the traction roller 6, increase with respect to above-mentioned path position concentrated load, the fiber footpath portion at this position can become the littler position of diameter.So, can periodically form this path position with respect to fiber 1.
The fiber that forms the path position is handled if carry out crush cutting in the crush cutting operation through subsequent treatment, is that the center cuts off with this path position, can make the sliver of the shearing length that possesses expectation.Become the diameter at the position of path as fiber footpath portion, must be in-5%～-40% scope with respect to the setting diameter restrictions in the fiber that forms the path position.If less than-5%, forming the position for path in crush cutting is handled, to increase the concentrated load that tractive force causes more difficult with respect to the setting diameter of fiber for the diameter at path position, then carry out in that the cut-out at this path position is more difficult.In addition, if the diameter at path position is compared greater than-40% with the setting diameter of fiber, the situation of fiber beam cutting will take place in the postprocessing working procedures such as the stretching after spinning, heat treatment then.
Now, suppose the traction roller 6 of use, the fiber 1 that traction spues from nozzle 2 with the hauling speed constant speed rotation of 10m/min.At this moment, if by control control engine 5, with the peripheral speed of counter-rotating roller 3 cycle with 6～8Hz, and supply with the amplitude of 2m/min with respect to above-mentioned hauling speed, then each cycle, the peripheral speed of counter-rotating roller 3 is 12m/min to the maximum, and minimum is 8m/min.
The travel distance of the fiber 1 that within 1 cycle in the cycle that the counter-rotating roller is supplied with, spues from nozzle 2, can think that with under the state of the hauling speed of keeping traction roller 6 substantially (10m/min), the distance that fiber 1 was walked is divided by the distance of the value gained in cycle in 1 second.At this moment, the travel distance of fiber 1 is approximately 2.7cm when the cycle of 6Hz, then be approximately 2.08cm when the cycle of 8Hz.Therefore, on each this travel distance, with respect to fiber 1, can form fiber footpath portion is the position of path.
If carry out 5 times stretching by stretching process with respect to such fiber 1 that has formed the path position, the distance of each several part walking also becomes 5 times distance, that is, when the cycle of 6Hz every about 13.9cm, every about 10.4cm, can form fiber footpath portion is the position of path when the cycle of 8Hz.Therefore, this length is predefined shearing length in the crush cutting operation, for example can for 14cm or 10.5cm length about equally.Also can be set at elongation is estimated that the sliver that obtains in this case has the highly shrinkable energy in interior length.Interval between the path position is adjusted, and can carry out arbitrarily by adjusting distance between counter-rotating roller diameter, average hauling speed, variable cycle, stretching ratio and counter-rotating roller and the yarn guiding chase comb etc.
In the above description, the peripheral speed of control inversion roller 3, although understand to be to be used for that the control engine 5 of this counter-rotating roller 3 of drive controlling carries out by control, but also can be by rotating the control engine that control drives the driving engine 7 of traction roller 6, when making this control engine cycle rotation change, the roller 3 that will reverse disposes as free roller and carries out.At this moment, by making the hauling speed of traction roller 6 periodically change, with respect to fiber 1, can periodically form fiber footpath portion is the position of path.In this case, the fiber footpath portion position that becomes path is formed between counter-rotating roller 3 and the traction roller 6.
In addition, undertaken also passable by the peripheral shape formation as described below of the roller 3 self that will reverse.That is,, also can use the rotating shaft of counter-rotating roller 3 and the different eccentric roller in central shaft position of counter-rotating roller 3 as counter-rotating roller 3.Also have, be formed with the counter-rotating roller of jut on the outer peripheral face of the peripheral shape that also can use roller as the counter-rotating roller of cam face or roller.Have again, use when being formed with the roller of jut on the roller outer peripheral face, can constitute the jut that is fixed on the roller outer peripheral face, in addition, also can be constituted as the jut 10 that jut is given prominence to from roller outer peripheral face 9 as shown in Figure 2 with freely haunting.Under the situation that jut freely haunts, can utilize by the sliding-contact of spring 13 bullets between the cam 12 that is provided with on the rotating shaft 11 of the jut 10 of disappearance direction and the roller 3 that reverses, and make the mechanism that jut 10 haunts, or the slide mechanism of the jut 10 of the not shown electric or hydraulic control control of haunting.
Peripheral shape by the roller 3 that will reverse constitutes as described above, can be so that peripheral speed increases in each specified period.The path position that forms in specified period can be by the extrusion position on the circumferencial direction of the roller diameter of adjusting counter-rotating roller 3, average hauling speed and counter-rotating roller etc., forms with arbitrary interval.And then, by adjusting the distance between counter-rotating roller 3 and the yarn guiding chase comb 4, the interval between also can the path position of adjustment cycle generation.Because by such adjustment, can adjust the interval between the path position of the fiber footpath portion that each cycle takes place, the formation at path position can be adjusted at interval with the crush cutting operation in the shearing length that preestablished maybe will extend and estimate about equally in interior length.
Because utilize traction roller 6 to adjust the hauling speed of fiber 1, form and the identical peripheral shape of above-mentioned counter-rotating roller by peripheral shape traction roller 6, also can be so that the hauling speed of traction roller 6 periodically changes.
By utilizing manufacturing installation of the present invention or manufacture method, with respect to the fiber after the spinning, can be with expectation uniformly-spaced form the position that fiber footpath portion becomes path.In addition, by utilizing the fiber that produces like this, can in the crush cutting operation, carry out rupturing operation with the shearing length of the shearing length that meets the expectation.Have, the sliver that produces like this can become with the cut fiber of the shearing length that meets the desired shearing length again.
Below be illustrated in the ensuing spinning process, with the fiber that uses the fiber that produces by manufacturing installation of the present invention and the change of counter-rotating roller is produced, the situation that the shearing length Pareto diagram when cutting off in the crush cutting operation compares.
