Next, above-mentioned textile apparatus 13 is described.
Fig. 2 is near the longitudinal section of the general configuration of the spindle front end of expression textile apparatus shown in Figure 1, and Fig. 3 is near the sectional elevation of the general configuration of the air nozzle of expression textile apparatus shown in Figure 1.
With reference to Fig. 2 and Fig. 3; Send the yarn direction along what made textile yarns 18 by fibre bundle 17, textile apparatus 13 has: guiding parts supporting mass 30, the nozzle body 33 that is formed with spatial portion 55, front end 42 sides are inserted the spindle 38 of above-mentioned spatial portion 55 from sending yarn direction downstream.Spatial portion 55 specifically constitutes; Comprise and form columned cylindric spatial portion 43 and circular cone shape spatial portion 49; This circular cone shape spatial portion 49 is connected with the downstream of cylindric spatial portion 43; And the diameter of the face of the upstream side that is connected is identical with the diameter of cylindric spatial portion 43, and enlarges towards the downstream.Nozzle body 33 and spindle 38 arranged coaxial.Spindle 38 is not to leave configuration with guiding parts supporting mass 30 and nozzle body 33 these the two modes that contact.Importing is formed on the wire guiding member supporting mass 30 sending the yarn direction to connect from the importing path 32 of the fibre bundle 17 that drafting system 12 is sent here.In addition, between the front end 42 of guiding parts supporting mass 30 and spindle 38, be formed with cylindric space, the i.e. chamber 36 of reversing, between the periphery wall 45 of the internal perisporium 44 of nozzle body 33 and spindle 38, be formed with space cylindraceous, be swirling eddy generating chamber 37.On spindle 38, connect spindle 38 axially, on shaft core position, be formed with yarn through hole 39.Above-mentioned importing path 32, swirling eddy generating chamber 37 and yarn are interconnected via counter-rotating chamber 36 through hole 39.
Guiding parts supporting mass 30 has the guiding parts 31 of needle-like, and the front end of this guiding parts 31 is projected in the counter-rotating chamber 36 as the part of cylindric spatial portion 43, towards the inlet of yarn through hole 39.Through this guiding parts 31, be imported into the fibre bundle 17 of counter-rotating in the chamber 36 a part, be that the core fibre that is positioned at the center of fibre bundle 17 is directed to yarn through hole 39.In addition, guiding parts 31 can freely be adjusted through the overhang of hole 39 sides to yarn.
Be formed with a plurality of air nozzles 34 on the nozzle body 33, these air nozzles 34 are towards cylindric spatial portion 43 and to sending yarn direction downstream to tilt a little, and have circular cross-section.The outlet 35 of air nozzle 34 is internal perisporium 44 upper sheds of nozzle body 33 in the peripheral wall surfaces of cylindric spatial portion 43.In addition, as shown in Figure 3, each air nozzle 34 equally spaced forms six on the tangential direction of the circle that the internal perisporium 44 of nozzle body 33 is constituted.Through not shown air feed mechanism,, thereby in counter-rotating chamber 36 and swirling eddy generating chamber 37, be created on the direction of the axle of spindle 38 swirling eddy with the certain speed rotation from each injection air equably of these air nozzles 34.In addition, because air nozzle 34 to sending yarn direction downstream to tilt a little, so air flow not only has the rotation composition, also has the composition that trend is sent the yarn direction.
Then, the manufacturing process to textile yarn 18 describes.
Fig. 4 schematically illustrates the figure of coiling fiber along the state of the peripheral wall surfaces rotation of the cylindric spatial portion of Fig. 2 and nozzle body shown in Figure 3.
Mainly with reference to Fig. 4, at first, 22 fibre bundles of seeing off 17 are imported into counter-rotating chamber 36 via the importing path 32 that is formed on the guiding parts supporting mass 30 from the front roller of drafting system 12.Fibre bundle 17 is on the guiding parts 31 about the coiling half cycle.In this counter-rotating chamber 36 and the swirling eddy generating chamber 37 that send yarn direction downstream that is connected counter-rotating chamber 36, along the generation of the direction shown in the arrow of Fig. 2 and Fig. 3 swirling eddy.Because this swirling eddy has the composition that trend is sent the yarn direction as stated, so, attracting outside air from importing path 32, fibre bundle 17 is imported into counter-rotating chamber 36 easily.
Then, be that core fibre is wound up on the guiding parts 31 on one side be imported into the center fiber of the fibre bundle 17 of counter-rotating chamber 36, Yi Bian be imported into yarn through hole 39.On the other hand, the end of sending yarn direction downstream of fiber 46 is wound up into and is imported into yarn on the above-mentioned core fibre through hole 39 while other fibers of fibre bundle 17 are promptly reeled.And throw off 22 from front roller the end of sending yarn direction upstream side of coiling fiber 46, send that kind of composition shown in the double dot dash line of Fig. 2 of yarn direction to reverse because of the trend of swirling eddy, and be imported into swirling eddy generating chamber 37.In addition, be restricted, thereby be imported into yarn, thereby can reduce the fiber that can not become textile yarn 18, will become fiber loss through hole 39 while the end of sending yarn direction downstream of coiling fiber 46 is wound up on the guiding parts 31.
Then, as shown in Figure 4, the coiling fiber 46 after the counter-rotating is wound up into and is continued to import yarn through on the core fibre in the hole 39 because of internal perisporium 44 rotations along nozzle body 33 of the rotation composition of swirling eddy.
Then, the reeled core fibre of fiber 46 is seen off from textile apparatus 13 through hole 39 via yarn.Like this, just, produced textile yarn 18.
At this, the diameter of the cylindric spatial portion 43 that is formed at nozzle body 33 is described.
Mainly with reference to Fig. 2, the diameter of establishing cylindric spatial portion 43 be T, air nozzle 34 with respect to the inclination angle with the axial plane orthogonal of cylindric spatial portion 43 be θ, from being L to the d/d P that grips of 22 coiling fibers that grip 46 to the length of yarn through the inlet center R in hole 39 by front roller.In addition because the width of fibre bundle 17 with regulation, thereby by front roller to 22 coiling fibers that grip 46 are d/d grip a little on, along front roller to 22 the axial width that also has regulation.Grip a P and be have the afore mentioned rules width grip a little in, gripping a little of constituting shortest path that fibre bundle 17 can advance.In addition, above-mentioned length L with from front roller to 22 grip path that a P advanced through the fibre bundle 17 of the center R of the inlet in hole 39 to yarn about equally.And, the coiling fiber 46 in above-mentioned length L and when counter-rotating from the inlet of yarn through hole 39 be exposed to the length of the part in the outside, when reversing the part of rotation length about equally.And, if it is had
The relation of T >=Lcos θ/π; Then the coiling fiber 46 that reverses because of swirling eddy when counter-rotating and from the end on observation of cylindric spatial portion 43 to vertical view, along the peripheral wall surfaces of cylindric spatial portion 43, be that the internal perisporium 44 of nozzle body 33 is roughly around a week.In addition, because the fibre length of coiling fiber 46 is not certain, so be not that all coiling fiber 46 is all roughly around a week.
Among Fig. 5; (1) is the expanded view of peripheral wall surfaces of the cylindric spatial portion of Fig. 2 and nozzle body shown in Figure 3 in the specific length scope; (2) be a plurality of coiling fibers of expression continuous sketch mapes of the state of rotation on the expanded view of (1), (3) be a plurality of coiling fibers of expression on sketch map of the state of rotation continuously than the little expanded view of the cylindric spatial portion diameter of (1).
With reference to Fig. 5 (1); In the textile apparatus 13 of relation with above-mentioned T >=Lcos θ/π; Cylindric spatial portion 43 axially on specific length H scope and from the end on observation of cylindric spatial portion 43 to vertical view, above-mentioned length L along the internal perisporium 44 of nozzle body 33 around a week.Wherein, specific length H be coiling fiber 46 rotation the zone cylindric spatial portion 43 axially on length.With reference to Fig. 5 (2), schematically show: the state that the consistent a plurality of coiling fibers 50,51,52,53 of above-mentioned length L during for example with counter-rotating rotate on the expanded view shown in Fig. 5 (1) continuously.This respectively reel fiber 50,51,52,53 when counter-rotating and from the end on observation of cylindric spatial portion 43 to vertical view, along the internal perisporium 44 of nozzle body 33 around a week.For example, in a coiling fiber 50, do not produce overlapping part.Then; With reference to Fig. 5 (3); Schematically show: the same with Fig. 5 (2), the state that for example consistent with the above-mentioned length L in when counter-rotating a plurality of coiling fibers 50,51,52,53 rotate on than the little expanded view of Fig. 5 (1) at the diameter of cylindric spatial portion 43 continuously.At this moment because compare the diameter of cylindric spatial portion 43 with Fig. 5 (1) little, so respectively reel fiber 50,51,52,53 when counter-rotating and from the end on observation of cylindric spatial portion 43 to vertical view more than a week.For example, in a coiling fiber 50, produce overlapping part a.
In addition, the coiling fiber 46 of counter-rotating and is wound up into and is continued to import yarn through on the core fibre in the hole 39 along 44 rotations of the internal perisporium of nozzle body 33 as above-mentioned, thereby makes textile yarn 18.At this moment, while rotating, the coiling fiber 46 of counter-rotating is directed to yarn gradually in swirling eddy generating chamber 37 through in the hole 39.Therefore; Shown in Fig. 5 (3); If respectively reel fiber 50,51,52,53 when counter-rotating and from the end on observation of cylindric spatial portion 43 to vertical view more than a week, the fiber 50,51,52,53 of then respectively reeling is imported into yarn and is easy to generate mutual winding through time in the hole 39.And shown in Fig. 5 (2); If respectively reel fiber 50,51,52,53 when counter-rotating and from the end on observation of cylindric spatial portion 43 to vertical view around a week, the fiber 50,51,52,53 of then respectively reeling is imported into yarn and is difficult for twining each other through time in the hole 39.In addition, if increase the diameter T of cylindric spatial portion 43, though coiling fiber 46 can be more than a week, the size of swirling eddy generating chamber 37 becomes too big thereby produces problem such as swirling eddy instability, and has influence on the whole size of textile apparatus 13.Therefore, only the diameter T of the cylindric spatial portion 43 of merely unlimited increase is also improper.
In weaving loom 10 with such textile apparatus 13; When counter-rotating and from the end on observation of cylindric spatial portion 43 to vertical view; The coiling fiber 46 that reverses because of swirling eddy along the peripheral wall surfaces of cylindric spatial portion 43 while drawing a circle around week roughly; That is, not overlapping in a coiling fiber 46.Therefore, when coiling fiber 46 rotated smoothly, the coiling fiber 46 in the rotation was difficult for twining each other each other, can produce the good textile yarn of texture 18.
In addition; Though in the above-described embodiment; The part of the spatial portion of nozzle body forms cylindric, but as long as from the end on observation of spatial portion to vertical view, the coiling fiber around week roughly, also can form other shapes such as circular cone shape along the peripheral wall surfaces of spatial portion.
In addition, though in the above-described embodiment, the part of the spatial portion of nozzle body forms cylindric, also can form cylindric by whole spatial portion.
In addition, though be formed with six air nozzles in the above-mentioned embodiment, be not certain formation like this, also can form other quantity.
At this, to the interval between the periphery wall 45 of the internal perisporium 44 of nozzle body 33 and spindle 38 and and the diameter of the outlet 35 of air nozzle 34 between relation describe.
With reference to Fig. 3 and Fig. 6, establish between the periphery wall 45 of the internal perisporium 44 of axially going up the nozzle body 33 in the specific length H scope and spindle 38 of spindle 38 be spaced apart S, air nozzle 34 with axial plane orthogonal on the diameter of outlet 35 be D.Length H be from removing of spindle 38 chamfered part cylindrical portion 40 the face that send the upstream side of yarn direction to the face in the downstream that is formed at cylindric spatial portion 43 on the nozzle body 33 spindle 38 axially on length.In length H scope, it is the cylindric of center that the cylindric spatial portion 43 of the internal perisporium 44 of formation nozzle body 33 and the cylindrical portion of spindle 38 40 form with same axle.Therefore, above-mentioned interval is S in length H scope, is definite value.
In addition, length H is set at least bigger than spindle 38 length in the axial direction in the zone of coiling fiber 46 rotations.In other words; If from front roller to 22 the yarn that grips the some spindle 38 inlet center through hole 39, fibre bundle the shortest path that can advance be that the radius of L, cylindric spatial portion 43 be R, air nozzle 34 with respect to the angle of inclination with the axial plane orthogonal of cylindric spatial portion 43 is θ, then length H is set to the length greater than (L-R) sin θ.Spindle 38 length in the axial direction in the zone of coiling fiber 46 rotations is roughly (L-R) sin θ.In addition, above-mentioned shortest path L is shorter than the effective fibre length of employed fiber.Effective fibre length is defined in the kind Co., Ltd. of " fiber brief guide-processing a piece of writing " ball, clear and the 4th printing distribution of second edition on January 20th, 61,10. in the 10.1.2 fiber long (1093～1094 pages) of standard test method.Because preseting length H as above-mentioned so apply the stable rotation air-flow to coiling fiber 46 integral body of rotation, can produce swirling eddy effectively.
Wherein, have 0.7D≤S≤relation of 1.3D, then can make the textile yarn with regulation yarn strength 18 of following explanation if textile apparatus 13 is configured.In addition, the injection pressure of the gas that sprays from each air nozzle 34 has nothing to do with the size of diameter D, is definite value.That is the emitted dose of gas time per units and changing of diameter D, from respectively going out 35 discharges with being in proportion.
Fig. 7 is that the yarn strength of expression when be maximum with 100% compares the figure with the relation of interval S/ air nozzle outlet diameter D.
With reference to Fig. 7, the yarn strength ratio the when longitudinal axis has adopted and has been maximum with 100%, transverse axis has adopted the interval S/ air nozzle outlet diameter D of prescribed limit.Showing and making S/ diameter D at interval is that each yarn strength of 0.5,0.7,0.8,1.0,1.2,1.3,1.5 o'clock compares the curve that is connected into.S/ diameter D is 0.5 o'clock at interval, and yarn strength is than about 78%; Equally, 0.7 o'clock about 87%; Equally, 0.8 o'clock about 95%; Equally, 1.0 o'clock about 100%; Equally, 1.2 o'clock about 92%; Equally, 1.3 o'clock about 87%; Equally, 1.5 o'clock about 77%.
At interval S/ diameter D is 0.5 o'clock, and S is too little at interval, and the air that sprays from air nozzle or stop or adverse current can not stably produce swirling eddy.Therefore, the coiling fiber 46 of counter-rotating is difficult to be wound up into equably on the core fibre, and yarn strength descends significantly.And S/ diameter D is 1.5 o'clock at interval, and S is too big at interval, and the air that sprays from air nozzle spreads apart, and can not produce the stable rotation air-flow.Therefore, the coiling fiber 46 of counter-rotating is difficult to be wound up into equably on the core fibre, and yarn strength descends significantly.
When making textile yarn 18, when being maximum with 100% the decline ratio of the yarn strength ratio that can allow be about 15%.In addition, except that yarn strength, textile yarn 18 also need be considered texture and fiber loss etc., therefore, the minimizing of texture paid the utmost attention to and fiber loss is also arranged and situation that yarn strength is reduced a little.The reduction ratio of yarn strength ratio is 15%, be that the yarn strength ratio is 85% to appear at interval S/ diameter D about 0.67 and at about 1.33 o'clock.Therefore, if at interval S/ diameter D is set in 0.7～1.3 the scope, then the yarn strength ratio is more than 85%.That is, if textile apparatus 13 is designed to have 0.7D≤S≤relation of 1.3D, by the yarn strength of the textile yarn 18 of these textile apparatus 13 manufacturings than being suppressed in 15% the reduction scope.
Be designed to have 0.7D≤S≤textile apparatus 13 of the relation of 1.3D in; The swirling eddy of rotation is difficult to spread, stagnation and adverse current, is stable between the periphery wall 45 of the internal perisporium 44 of nozzle body 33 and spindle 38, so that the conduct in the fibre bundle 17 imports to the rotation of coiling fiber 46 of the fiber in the swirling eddy generating chamber is also stable.Thereby, can make textile yarn with the yarn strength of stipulating, the yarn strength ratio when promptly being maximum with 100% with the yarn strength more than 85%.In addition, the spindle 38 in the length H scope and the shape of cylindric spatial portion 43 form cylindric respectively, so swirling eddy flows smoothly, can produce swirling eddy effectively.
In addition, though in the above-described embodiment, the spatial portion of nozzle body and spindle form cylindric in the scope of regulation, as long as the interval of the periphery wall of the internal perisporium of nozzle body and spindle is certain, also can form other shapes such as the frustum of a cone.
In addition, though in the above-described embodiment, the part of the spatial portion of nozzle body forms cylindric, and it is cylindric also can be that spatial portion whole form.
In addition, though form six air nozzles in the above-described embodiment, be not certain formation like this, also can be other quantity.
Wherein, the sectional area A of swirling eddy generating chamber 37 shown in Figure 3 spindle 38 axially on length H scope shown in Figure 8 in be definite value.Sectional area A be and the axial plane orthogonal of spindle 38 on, the sectional area in circular zone between the periphery wall 45 of the internal perisporium 44 of nozzle body 33 and cylindrical portion 40.Length H be the face from the face that send the upstream side of yarn direction of the cylindrical portion except that the chamfered part of spindle 38 40 to the downstream that is formed at cylindric spatial portion 43 on the nozzle body 33 spindle 38 axially on length.In length H scope, it is the cylindric of center that the cylindric spatial portion 43 of the internal perisporium 44 of formation nozzle body 33 and the cylindrical portion of spindle 38 40 form with same axle.Therefore, in the scope of length H, sectional area A is a definite value.
In addition, length H is set at least bigger than spindle 38 length in the axial direction in the zone of coiling fiber 46 rotations.In other words; If from front roller to 22 the yarn that grips the some spindle 38 inlet center through hole 39,17 shortest paths that can advance of fibre bundle are that the radius of L, cylindric spatial portion 43 be R, air nozzle 34 with respect to the angle of inclination with the axial plane orthogonal of cylindric spatial portion 43 is θ, then length H is set to the length greater than (L-R) sin θ.The zone of coiling fiber 46 rotation spindle 38 axially on length be roughly (L-R) sin θ.In addition, above-mentioned shortest path L is shorter than the effective fibre length of employed fiber.Effective fibre length is defined in the kind Co., Ltd. of " fiber brief guide-processing a piece of writing " ball, clear and the 4th printing distribution of second edition on January 20th, 61,10. in the 10.1.2 fiber long (1093～1094 pages) of standard test method.Because preseting length H as above-mentioned so apply the stable rotation air-flow to coiling fiber 46 integral body of rotation, can produce swirling eddy effectively.
In above-mentioned length H scope, each air nozzle 34 respectively export 35 be formed on internal perisporium 44 send yarn direction upstream side.Outlet 35 is not its part but the whole scope that enters into above-mentioned length H that forms.
Then, the manufacturing process to textile yarn 18 describes.
Mainly with reference to Fig. 2, at first the front roller from drafting system 12 is imported into counter-rotating chamber 36 to 22 fibre bundles of seeing off 17 via the importing path 32 that is formed on the guiding parts supporting mass 30.Fibre bundle 17 is on the guiding parts 31 about the coiling half cycle.In this counter-rotating chamber 36 and the swirling eddy generating chamber 37 that send yarn direction downstream that is connected in counter-rotating chamber 36, on the direction shown in the arrow of Fig. 2 and Fig. 3, produce swirling eddy.Because this swirling eddy has the composition that trend is sent the yarn direction as stated, so outside air is attracted from importing path 32, fibre bundle 17 is imported into counter-rotating chamber 36 easily.
Then, be that core fibre is wound up on the guiding parts 31 on one side import to the center fiber of the fibre bundle 17 of counter-rotating chamber 36, Yi Bian be imported into yarn through hole 39.And promptly the reel end of sending yarn direction downstream of fiber 46 of other fibers of fibre bundle 17 is imported into yarn through hole 39 to be wound up into state on the above-mentioned core fibre.And the end of sending yarn direction upstream side of coiling fiber 46 is left 22 from front roller, because of the composition that send the yarn direction that tends to swirling eddy reverses shown in the double dot dash line of Fig. 2, is imported into swirling eddy generating chamber 37.
Then, the coiling fiber 46 of counter-rotating is rotated along the internal perisporium 44 of the nozzle body 33 rotation composition because of swirling eddy, and is wound up into and continues to be imported into yarn through on the core fibre in the hole 39.
Then, the reeled core fibre of fiber 46 is seen off from textile apparatus 13 through hole 39 via yarn.Like this, just, produced textile yarn 18.
In such textile apparatus 13, each air nozzle 34 respectively export 35 not towards counter-rotating chamber 36 as large space.Thereby, can suppress sharply to spread from the air that air nozzle 34 sprays.In addition, owing to being swirling eddy generating chamber 37 injection airs of definite value, so air intensity continues the turbulent flow of long distance and reduction swirling eddy to sectional area A.And, because that swirling eddy generating chamber 37 its cross sections form is cylindric, so air flows swimmingly.Therefore, can make swirling eddy stable, and produce swirling eddy effectively.If can produce swirling eddy effectively, the coiling fiber 46 in the then above-mentioned manufacturing process is also stable to the coiling of core fibre, can improve the yarn strength of textile yarn 18.
In addition, though in above-mentioned, the spatial portion of nozzle body and spindle form cylindric in prescribed limit, as long as the area of the swirling eddy generating chamber on the cross section is definite value in prescribed limit, also can form other shape.
In addition; Though in the above-described embodiment; Form the circle of identical size on the optional position of each shape in length H scope on the cross section of the internal perisporium of nozzle body and the periphery wall of spindle; But, also can form the circle of different sizes as long as the area of the swirling eddy generating chamber on the cross section is a definite value.
In addition, though in the above-described embodiment, what the outlet of each air nozzle was formed on internal perisporium send yarn direction upstream side, as long as in length H scope, also can be formed on the optional position.
In addition, though form six air nozzles in the above-described embodiment, be not certain formation like this, also can form other quantity.
