Below the main process that briefly explains above-mentioned textile apparatus generation yarn with Fig. 2 and Fig. 3.
The fiber bundle F of sending, being stretched from the preliminary roller 6 of stretching device D enters the fiber entrance hole 14a of knitting needle frame 14, enters then among the weaving chamber p1 that forms between the top ends of jet element 15 and rotation or irrotational hollow guide shaft body 21.In weaving chamber p1, the air of the air jet hole 15a ejection from be arranged in jet element 15 forms swirling eddy, Yi Bian 21 rotations of swirling eddy one edge hollow guide shaft body flow into air chamber 23 downwards, discharges from attracting hole 17c through pipe 17d then.Because the effect of the air of the ejection of the air jet hole 15a from be arranged in jet element 15, produce near the inlet of the fiber entrance hole 14a of preliminary roller 6 sides of knitting needle frame 14 and attract air-flow, therefore the fiber bundle F of sending, being stretched from preliminary roller 6 is inhaled into the fiber entrance hole 14a of knitting needle frame 14.
The fiber bundle F of coming out from the fiber entrance hole 14a of knitting needle frame 14 is wrapped on the knitting needle 14b of top near the inlet 21a1 configuration of the hollow channel 21a of hollow guide shaft body 21, Yi Bian be imported among the hollow channel 21a of hollow guide shaft body 21 on one side.And, the part of the fiber f of the fiber bundle F that formation is come out from the fiber entrance hole 14a of knitting needle frame 14, its top is wound on the textile strand Y ' that constantly generates in the hollow channel 21a of hollow guide shaft body 21, be imported among the hollow channel 21a of hollow guide shaft body 21, in addition, the part of the fiber f of the fiber bundle F that formation is come out from the fiber entrance hole 14a of knitting needle frame 14, its top is wound on the textile strand Y ' that constantly generates in the hollow channel 21a of hollow guide shaft body 21, be imported among the hollow channel 21a of hollow guide shaft body 21, and end f1a passes through the interior swirling eddy that produces of weaving chamber p1 thereafter, the top ends revolution of one edge hollow guide shaft body 21, the periphery wall buckling of one edge hollow guide shaft body 21 is (in the following hollow channel 21a that top ends is inserted hollow guide shaft body 21, rearward end f1a disposes like that along the periphery wall of the top ends of hollow guide shaft body 21, crooked fiber is called " counter-rotating fiber ", adds Reference numeral f1).And, along with moving of the textile strand Y ' in the generative process, the rearward end f1a of counter-rotating fiber f1 is during near the inlet 21a1 of the hollow channel 21a of hollow guide shaft body 21, the rearward end f1a of counter-rotating fiber f1 passes through swirling eddy, one side is at the whirling on every side of the textile strand Y ' of the generative process of the hollow channel 21a that is arranged in hollow guide shaft body 21, be wrapped in its periphery on one side, generate textile strand Y.Like this, generate by state and import core fibre that the fiber f in the hollow channel 21a of hollow guide shaft body 21 constitutes and the textile strand Y of the fibroplastic real sth. made by twisting state of winding that constitutes by the counter-rotating fiber f1 that is wrapped in around the core fibre with near linear.Because fiber bundle F is to be wrapped on the knitting needle 14b temporarily, twist with the fingers direction expansion even be rotated a part that air-flow adds to preliminary roller 6, this expansion is also stoped by knitting needle 14b, so the situation that does not exist the fiber bundle F sent here from preliminary roller 6 to be twisted.
Below mainly jet element 15 and the detailed structure of hollow guide shaft body 21 and the relation between them are described with Fig. 4 and Fig. 5.
Be formed with through hole 24 at jet element 15 along its axis direction, through hole 24 is by constituting with the lower part: the certain cylindric spatial portion 24a of inlet portion, internal diameter that constitutes the through hole 24 of knitting needle frame 14 sides (the importing side of fiber bundle F) that are positioned at through hole 24, the 1st circular cone shape spatial portion 24b that is connected with cylindric spatial portion 24a, the 2nd circular cone shape spatial portion 24c that is connected with the 1st circular cone shape spatial portion 24b and the 3rd circular cone shape spatial portion 24d that is connected with the 2nd circular cone shape spatial portion 24c.Constitute the angle theta 1 of the centre line L 1 of the bus of internal perisporium face 15b of jet element 15 of the 1st circular cone shape spatial portion 24b and through hole 24, the angle theta 2 of the bus of the internal perisporium face 15c of the jet element 15 of ratio formation the 2nd circular cone shape spatial portion 24c and the centre line L 1 of through hole 24 is big, and, constitute the angle theta 2 of the centre line L 1 of the bus of internal perisporium face 15c of jet element 15 of the 2nd circular cone shape spatial portion 24c and through hole 24, littler than the angle theta 3 of the centre line L 1 of the bus of the internal perisporium face 15d of the jet element 15 that constitutes the 3rd circular cone shape spatial portion 24d and through hole 24.Promptly, constitute the angle theta 3 of the centre line L 1 of the bus of internal perisporium face 15d of jet element 15 of the 3rd circular cone shape spatial portion 24d and through hole 24, bus than the internal perisporium face 15b of the jet element 15 that constitutes the 1st circular cone shape spatial portion 24b is little with the angle theta 1 of the centre line L 1 of through hole 24, and is bigger than the angle theta 2 of the centre line L 1 of the bus of the internal perisporium face 15c of the jet element 15 of formation the 2nd circular cone shape spatial portion 24c and through hole 24.
Be arranged in a plurality of air jet hole 15a in the jet element 15, approximately half is positioned on the internal perisporium face 15e of the jet element 15 that constitutes cylindric spatial portion 24a its outlet 15a1, and remaining pact half be positioned at from the dirty end of the internal perisporium face 15e of the jet element 15 that constitutes cylindric spatial portion 24a and enlarge on the internal perisporium face 15b that is inclined to horn-like, as to constitute the 1st circular cone shape spatial portion 24b jet element 15 to downstream side.
Hollow guide shaft body 21 disposes like this: its center line L2 is consistent with the centre line L 1 of through hole 24 in being arranged in jet element 15.Hollow guide shaft body 21 is made of with the 3rd 21e of circular cone shape portion that is connected with cylindrical portion 21d the 1st 21b of circular cone shape portion that constitutes its top ends, the 2nd 21c of circular cone shape portion that is connected with the 1st 21b of circular cone shape portion, the cylindrical portion 21d that is connected with the 2nd 21c of circular cone shape portion.And, the angle theta 4 of the centre line L 2 of the bus of the 2nd 21c of circular cone shape portion and hollow guide shaft body 21 is bigger than the angle theta 5 of the centre line L 2 of the bus of the 1st 21b of circular cone shape portion and hollow guide shaft body 21.And, hollow guide shaft body 21 is configured to its 1st circular cone shape 21b of portion and is arranged in the through hole 24 that is arranged in jet element 15, and air jet hole 15a is located in the jet element 15 like this: from the air of air jet hole 15a ejection, on the tangential direction of the fillet part 21b1 of the upper reaches vertex angle part of the 1st 21b of circular cone shape portion that is formed at hollow guide shaft body 21, and ejection downwards.
At the internal perisporium face 15b of formation the 1st circular cone shape spatial portion 24b of jet element 15, constitute the internal perisporium face 15c of the 2nd circular cone shape spatial portion 24c and enough become the internal perisporium face 15d of the 3rd circular cone shape spatial portion 24d, and be formed with the space S of approximate tubular between the periphery wall 21b2 of the 1st 21b of circular cone shape portion of hollow guide shaft body 21.This space S swirling eddy that to be the rearward end f1a that is used to insert the counter-rotating fiber f1 in the hollow channel 21a of hollow guide shaft body 21 form by the air from air jet hole 15a ejection and along the space of the periphery wall buckling of the top ends of hollow guide shaft body 21, but also have the effect that is discharged to the exhaust space of air chamber 23 as air from air jet hole 15a ejection.
Owing to make the angle theta 2 of the centre line L 1 of the bus of internal perisporium face 15c of the jet element 15 that constitutes the 2nd circular cone shape spatial portion 24c and through hole 24, the angle theta 3 of the bus of the internal perisporium face 15d of the jet element 15 of ratio formation the 3rd circular cone shape spatial portion 24d and the centre line L 1 of through hole 24 is little, therefore at the internal perisporium face 15c of the jet element 15 that constitutes the 2nd circular cone shape spatial portion 24c and the intersection of the internal perisporium face 15d of the jet element 15 that constitutes the 3rd circular cone shape spatial portion 24d, formed the annular protrusion 25 that protrudes to the direction of the periphery wall 21b2 of the 1st 21b of circular cone shape portion of hollow guide shaft body 21, in this position as the protuberance 25 of contraction flow region, the internal perisporium face 15c of formation the 2nd circular cone shape spatial portion 24c of jet element 15 and constitute the internal perisporium face 15d of the 3rd circular cone shape spatial portion 24d, and the contraction maximum of the space S that forms between the periphery wall 21b2 of the 1st 21b of circular cone shape portion of hollow guide shaft body 21.
The bus of not necessarily leaveing no choice but the internal perisporium face 15c by making the jet element 15 that constitutes the 2nd circular cone shape spatial portion 24c and the angle theta 2 of the centre line L 1 of through hole 24 form above-mentioned protuberance 25 than the angle theta 3 of the centre line L 1 of the bus of the internal perisporium face 15d of the jet element 15 that constitutes the 3rd circular cone shape spatial portion 24d and through hole 24 is little.Can for example not form the 3rd circular cone shape spatial portion 24d yet, and the through hole 24 that makes jet element 15 is formed with the 2nd circular cone shape spatial portion 24c that is connected with the 1st circular cone shape spatial portion 24b by cylindric spatial portion 24a, the 1st circular cone shape spatial portion 24b that is connected with cylindric spatial portion 24a, and on the internal perisporium face 15c of the 2nd circular cone shape spatial portion 24c, protrude annular protrusion, form and above-mentioned same protuberance 25.
But, as mentioned above, though air from the air jet hole 15a of jet element 15 ejection, for on the tangential direction of the fillet part 21b1 in the bight, upper end of the 1st 21b of circular cone shape portion that is formed at hollow guide shaft body 21, spraying to downstream side, and hollow guide shaft body 21 around in the shape of a spiral shape to the swirling eddy of dirty side flow, but this swirling eddy comprises that making the rotation composition of counter-rotating fiber f1 along the periphery wall of the top ends of hollow guide shaft body 21 towards the circumferencial direction rotation and the axial flow composition that counter-rotating fiber f1 is moved along the axis direction of hollow guide shaft body 21, this axial flow composition also is to have the gas of effect that rearward end f1a with counter-rotating fiber f1 is pressed in the periphery wall of hollow guide shaft body 21.If the rotation composition of swirling eddy is big, then constitute the core fibre of textile strand and twine in the fiber, the ratio of twining fiber increases, and if the rotation composition is little, the ratio of then twining fiber reduces.
The rotation composition of swirling eddy and axial flow components in proportions, can be by changing the projecting inward such protuberance that forms 25 of space S that between the periphery wall 21b2 of the 1st 21b of circular cone shape portion of internal perisporium face 15b, 15c, 15d and the hollow guide shaft body 21 of above-mentioned jet element 15, forms to the projecting inward amount of space S, in other words, the sectional area by changing protuberance 25 place's space S (with center line (axis) L1 of jet element 15 area of the face of orthogonal mutually) is adjusted.
If make protuberance 25 big to the projecting inward amount of space S, make the sectional area of protuberance 25 place's space S little, in other words, make the amount of contraction of space S big, the then rotation composition of swirling eddy increase, axial flow composition reduce, and the ratio that therefore constitutes the winding fiber of textile strand increases.
If protuberance 25 is excessive to the projecting inward amount of space S, the sectional area of protuberance 25 place's space S is too small, then hinder swirling eddy to the flowing of air chamber 23 directions, the axial flow composition of swirling eddy is extremely low, and then the swirling eddy reverse flow.Like this, if swirling eddy reverse flow, then near the attraction air-flow that produces the inlet of the fiber entrance hole 14a of preliminary roller 6 sides of knitting needle frame 14 dies down, therefore should attract the attraction step-down to the fiber entrance hole 14a of knitting needle frame 14 direction of air-flow to fiber bundle F, the textile strand intensity step-down that generates, even can not generate textile strand.And if protuberance 25 is excessive to the projecting inward amount of space S, then swirling eddy produces disorder, and the rearward end f1a of counter-rotating fiber f1 is disarrayed the physical characteristic of the textile strand of generation and degraded appearance.Though can be by increasing the amount of contraction of protuberance 25 place's space S, in other words, by reducing the sectional area of protuberance 25 place's space S, increase the rotation composition of swirling eddy, increase the ratio of the winding fiber that constitutes textile strand, but the effect that the rearward end f1a of fiber f1 is pressed on the periphery wall 21b2 of hollow guide shaft body 21 because the axial flow composition will reverse diminishes, then become its opposite effect, the winding power of winding fiber is step-down also, the intensity step-down of the textile strand of generation, perhaps, as mentioned above, the axial flow composition is extremely low, and swirling eddy flows in the other direction, therefore must suitably set the sectional area of protuberance 25 place's space S.
If reduce the sectional area of protuberance 25 to the projecting inward amount of space S, increase protuberance 25 place's space S, the then axial flow composition of swirling eddy increase, rotation composition reduce, and the ratio that therefore constitutes the winding fiber of textile strand reduces.And, if the axial flow composition of swirling eddy increases, the resistance when the fiber f1 that then reverses is inhaled in the hollow channel 21a of hollow guide shaft body 21 becomes big, therefore, counter-rotating fiber f1 strengthens to the power that the core fibre that constitutes textile strand twines, and can make to twine textile strand tight and that intensity increases.
But, if protuberance 25 is too small to the projecting inward amount of space S, the sectional area of protuberance 25 place's space S is excessive, then the axial flow composition of swirling eddy becomes excessive, swirling eddy became strong to the mobile of downstream side, therefore the fiber that constitutes fiber bundle F separates from fiber bundle F, increased floating fiber, promptly so-called fiber loss.When such fiber loss increases, can reduce the fibre weight that constitutes the textile strand that generates certainly, so the intensity step-down of textile strand.And if the axial flow composition of swirling eddy becomes excessive, the winding fiber that then is wrapped on the core fibre tails off, the intensity step-down of textile strand.
Fig. 6 has represented the intensity (gram/spy: gr/tex) and the experimental result of the relation of the sectional area (square millimeter) of protuberance 25 place's space S of the textile strand that generates.
The textile strand of the textile strand intensity of the practicality that purposes is wider in order to generate, 8 gram/spies are above, the sectional area of protuberance 25 place's space S must be roughly at 6～15 square millimeters.Particularly the purposes scope is wide in order to generate, the above better textile strand of the intensity of textile strand of 10 gram/spies, and the sectional area that should make protuberance 25 place's space S is roughly at 7～12 square millimeters.
And, because the allocation position of above-mentioned protuberance 25 also influences the physical characteristic and the weaving property of textile strand, therefore must suitably adjust the distance H 1 of protuberance 25 to the upstream side end face of hollow guide shaft body 21 (comprising the inlet 21a1 of hollow channel 21a, the upstream side end face vertical) 21f with the centre line L 2 of hollow guide shaft body 21.
If protuberance 25 is too short with the distance H 1 of the upstream side end face 21f of hollow guide shaft body 21, counter-rotating fiber f1 contacts with protuberance 25, hinders the counter-rotating of fiber, and the ratio that then constitutes the winding fiber of textile strand reduces, generate and twine the textile strand that fiber is few, core fibre is many, the intensity step-down of textile strand.And, if counter-rotating fiber f1 contacts with protuberance 25, then there is the situation of the rearward end f1a bending of counter-rotating fiber f1, so intensity step-down, the degraded appearance of textile strand.
If protuberance 25 is long with the distance H 1 of the upstream side end face 21f of hollow guide shaft body 21, then constitute the end 15d1 of internal perisporium face 15d of jet element 15 of the 3rd circular cone shape spatial portion 24d of jet element 15, and the gap turn narrow between the end of the periphery wall 21b2 of the 1st 21b of circular cone shape portion of hollow guide shaft body 21, be mixed in field trash in the fiber bundle F, that disperse etc. and be blocked in this narrow gap, so-called " obstruction " takes place easily.If such obstruction takes place, then hinder swirling eddy to the flowing of air chamber 23, the axial flow composition is extremely low, and then the swirling eddy reverse flow, and the intensity step-down of textile strand or can not generate textile strand hinders the weaving property.
The 2nd 21c of circular cone shape portion that constitutes hollow guide shaft body 21 had better not be arranged in the through hole 24 that is arranged in jet element 15, that is, preferably have only the 1st 21b of circular cone shape portion to be arranged in the through hole 24 that is arranged in jet element 15.Because the 2nd 21c of circular cone shape portion is big with respect to the angle θ 5 of bus centre line L 2 with respect to angle θ 4 to the 1 21b of circular cone shape portion of centre line L 2, in other words, because the outer peripheral face of the 2nd 21c of circular cone shape portion expands outwardly more than the outer peripheral face of the 1st 21b of circular cone shape portion, if therefore the 2nd 21c of circular cone shape portion is arranged in the through hole 24 that is arranged in jet element 15, then space S has been shunk at the export department S1 place of space S, thus, can damage above-mentioned protuberance 25 is formed on action effect in the space S.
But, by making the 2nd 21c of circular cone shape portion be positioned at the downstream side (S1 of the export department side of space S) of the protuberance 25 that constitutes contraction flow region, not only can suitably adjust the rotation composition and the axial flow components in proportions of swirling eddy by protuberance 25, and play the effect that needn't form the space S between jet element 15 and the hollow guide shaft body 21 too much by the 2nd 21c of circular cone shape portion.
Because the outlet 15a1 of the air jet hole 15a of jet element 15 is positioned at the size of the internal diameter W1 of cylindric spatial portion 24a, influence the physical characteristic and the weaving property of textile strand, therefore must make this internal diameter W1 size to fit.
If the internal diameter W1 of cylindric spatial portion 24a is little, then the rotation girth of swirling eddy shortens, and the air velocity of the rotation composition of swirling eddy increases.Therefore, make the revolving force of counter-rotating fiber f1 become big, be wrapped on the core fibre, generate and extort textile strand tight, that intensity increases with big winding power.But if the internal diameter W1 of cylindric spatial portion 24a is too small, then the counter-rotating space of fiber narrows down, and fiber reverses and becomes difficult, therefore, and owing to the ratio reduction of the winding fiber that is made of counter-rotating fiber f1, the ratio of core fibre increase, so the intensity step-down of textile strand.And, if the internal diameter W1 of cylindric spatial portion 24a is too small, then the air velocity of the rotation composition of swirling eddy too increases, therefore, the rearward end f1a of fiber f1 is pressed in the effect reduction on the periphery wall 21b2 of hollow guide shaft body 21 because the axial flow composition will reverse, so become its opposite effect, the winding power of winding fiber is step-down also, the intensity step-down of textile strand.
If the internal diameter W1 of cylindric spatial portion 24a is excessive, then because the girth of swirling eddy rotation is long, the air velocity of the rotation composition of swirling eddy diminishes.Therefore, the revolving force of counter-rotating fiber f1 diminishes, and the power that counter-rotating fiber f1 is wrapped on the core fibre dies down, and generates and twines not tight textile strand, the intensity step-down of textile strand.And if the internal diameter W1 of cylindric spatial portion 24a is excessive, the air velocity of the rotation composition of swirling eddy becomes too small, therefore, because the axial flow composition of swirling eddy becomes excessive, the generation core fibre is many, the few textile strand of winding fiber, the intensity step-down of textile strand.
The internal diameter W1 of above-mentioned cylindric spatial portion 24a is preferably roughly in 4～6 millimeters scope.If the internal diameter W1 of cylindric spatial portion 24a is less than 4 millimeters, the internal diameter W1 of then cylindric spatial portion 24a is too small, as mentioned above, the counter-rotating space of fiber narrows down, it is difficult that fiber counter-rotating becomes, therefore, and the ratio step-down of the winding fiber that constitutes by counter-rotating fiber f1, the ratio of core fibre increases, so the intensity step-down of textile strand.If the internal diameter W1 of cylindric spatial portion 24a surpasses 6 millimeters, the internal diameter W1 of then cylindric spatial portion 24a becomes excessive, as mentioned above, the revolving force of counter-rotating fiber f1 diminishes, the power that counter-rotating fiber f1 is wrapped on the core fibre dies down, and generates and twines not tight textile strand, the intensity step-down of textile strand.
Because the size of the external diameter W2 on the top of hollow guide shaft body 21 also influences the physical characteristic and the weaving property of textile strand, the size that therefore must make this external diameter W2 suitably.In addition, the external diameter W2 on the top of so-called hollow guide shaft body 21 is meant the distance between an antinode X1, the X1 that the upstream side end face 21f of extended line L3, L3 and hollow guide shaft body 21 of relative a pair of bus of the periphery wall 21b2 of the 1st 21b of circular cone shape portion intersects.
If the external diameter W2 on the top of hollow guide shaft body 21 is little, then the outlet 15a1 of the air jet hole 15a of jet element 15 is elongated to the distance of the fillet part 21b1 of hollow guide shaft body 21, therefore, big with the external diameter W2 on the top of hollow guide shaft body 21, the outlet 15a1 of the air jet hole 15a of jet element 15 compares in short-term to the distance of the fillet part 21b1 of hollow guide shaft body 21, the rotation composition of the swirling eddy of the top end of hollow guide shaft body 21 diminishes to the effect of fiber f, counter-rotating fiber f1 diminishes to the strong winding power of core fibre, and it is not tight therefore to generate winding, the textile strand that intensity is low.And, if the rotation composition of swirling eddy diminishes to the effect of fiber f, then generate core fibre many, twine the few textile strand of fiber, the intensity step-down of textile strand.
And the size influence of the external diameter W2 on the top of hollow guide shaft body 21 is wrapped in the winding angle (twining the angle of inclination of fiber with respect to the length direction of textile strand) of the counter-rotating fiber f1 on the core fibre.That is, compare when big with the external diameter W2 on the top of hollow guide shaft body 21, the external diameter W2 on the top of hollow guide shaft body 21 hour, the winding angle of the winding fiber that is made of counter-rotating fiber f1 became big.That is, twine fiber more, near horizontal line (with the perpendicular direction of the length direction of textile strand) with respect to the angle of inclination of the length direction of textile strand.And, if the external diameter W2 on the top of hollow guide shaft body 21 is too small, the winding angle of winding fiber becomes excessive, the intensity step-down of the textile strand of Sheng Chenging then, and, when the winding angle excessive, that twine fiber of the external diameter W2 on the top of hollow guide shaft body 21 is too small, the same step-down of intensity of the same textile strand that generates.
In addition, if the external diameter W2 on the top of hollow guide shaft body 21 is too small, then the air from the air jet hole 15a of jet element 15 ejection does not contact with the fillet part 21b1 in the bight, upper end that is formed at hollow guide shaft body 21, depart from easily, therefore can not produce sufficient swirling eddy, generate the low textile strand of intensity.
And if the external diameter W2 on the top of hollow guide shaft body 21 is excessive, then the counter-rotating space of fiber narrows down, and it is difficult that fiber counter-rotating becomes, and therefore the ratio of the winding fiber that is made of counter-rotating fiber f1 reduces, the ratio of core fibre increases, so the intensity step-down of textile strand.And, if the external diameter W2 on the top of hollow guide shaft body 21 is excessive, then the outlet 15a1 of the air jet hole 15a of jet element 15 becomes too short to the distance of the fillet part 21b1 of hollow guide shaft body 21, swirling eddy tails off to the capacity of air chamber 23, so swirling eddy is to mobile being blocked of air chamber 23 directions, it is extreme low that the axial flow composition becomes, perhaps swirling eddy reverse flow, therefore, near the attraction air flow that produces the inlet of the fiber entrance hole 14a of preliminary roller 6 sides of knitting needle frame 14 is to the attraction step-down to the fiber entrance hole 14a of knitting needle frame 14 direction of fiber bundle F, the intensity step-down of textile strand under opposite extreme situations, can not generate textile strand.
Therefore, consider above-mentioned situation, suitably set the external diameter W2 on the top of hollow guide shaft body 21.
Fig. 7 has represented the experimental result of the relation between the external diameter W2 (millimeter) on top of the intensity (gram/spy) of the textile strand that generates and hollow guide shaft body 21.
The textile strand of the textile strand intensity of the practicality that purposes is wider in order to generate, 10 gram/spies are above, the external diameter W2 on the top of hollow guide shaft body 21 is preferably roughly at 2.4～3.9 millimeters.
If the external diameter W2 on the top of hollow guide shaft body 21 is less than 2.4 millimeters, then as mentioned above, the rotation composition of swirling eddy is too small to the effect of fiber f, generates to twine the low textile strand of intensity that fiber is few, core fibre is many; Perhaps, from the air of the air jet hole 15a of jet element 15 ejection, the fillet part 21b1 with the bight, upper end that is formed at hollow guide shaft body 21 contact, skew, so the effect deficiency of swirling eddy easily, the low textile strand of generation intensity.And, if the external diameter W2 on the top of hollow guide shaft body 21 is above 3.9 millimeters, then as mentioned above, ratio step-down owing to the winding fiber that constitutes by counter-rotating fiber f1, the ratio of core fibre increases, therefore the intensity step-down of textile strand not only, and the outlet 15a1 of the air jet hole 15a of jet element 15 becomes too short to the distance of the fillet part 21b1 of hollow guide shaft body 21, swirling eddy is suppressed to the exhaust of air chamber 23 directions, so, swirling eddy is to mobile being blocked of air chamber 23 directions, it is extreme low that the axial flow composition becomes, perhaps, the swirling eddy reverse flow, therefore near the attraction air-flow that produces the inlet of the fiber entrance hole 14a of preliminary roller 6 sides of knitting needle frame 14 is to the attraction step-down to the fiber entrance hole 14a of knitting needle frame 14 direction of fiber bundle F, the intensity step-down of textile strand under opposite extreme situations, can not generate textile strand.
Because swirling eddy is from the space S that forms between the periphery wall 21b2 of the internal perisporium face 15b of formation the 1st circular cone shape spatial portion 24b of jet element 15, the internal perisporium face 15d that constitutes the internal perisporium face 15c of the 2nd circular cone shape spatial portion 24c and constitute the 3rd circular cone shape spatial portion 24d and the 1st 21b of circular cone shape portion of hollow guide shaft body 21 discharge area to air chamber 23 discharges, also influence the physical characteristic and the weaving property of textile strand, therefore, must make the S of export department 1 place space S discharge area size suitably.
Compare when big with above-mentioned discharge area, the rotation composition of this discharge area hour swirling eddy increases, the axial flow composition reduces, so the ratio of the winding fiber of textile strand increases, the ratio of core fibre reduces.And, to compare when big with above-mentioned discharge area, this discharge area hour swirling eddy is suppressed to the exhaust of air chamber 23, and therefore, swirling eddy is to mobile being blocked of air chamber 23 directions.
If above-mentioned discharge area is too small, then swirling eddy is suppressed to the exhaust of air chamber 23, and therefore, swirling eddy is to mobile being blocked of air chamber 23 directions, and the axial flow composition is extremely low, perhaps swirling eddy reverse flow.Like this, if the axial flow composition of swirling eddy is extremely low, perhaps swirling eddy reverse flow, then near the attraction air flow that produces the inlet of the fiber entrance hole 14a of preliminary roller 6 sides of knitting needle frame 14 dies down, therefore should attract the attraction step-down to the fiber entrance hole 14a of knitting needle frame 14 direction of air-flow to fiber bundle F, the textile strand intensity decreases that generates under extreme case, can not generate textile strand.And, because the rotation composition of swirling eddy is strong excessively, the effect that the rearward end f1a of fiber f1 is pressed on the periphery wall 21b2 of hollow guide shaft body 21 of will reverse of axial flow composition is low, so becomes its opposite effect, the winding power of twining fiber is also low, generates the low textile strand of intensity.
And if above-mentioned discharge area is excessive, then the axial flow composition of swirling eddy becomes excessive, and swirling eddy is to the mobile grow of downstream side, and the fiber that constitutes fiber bundle F separates from fiber bundle F, and floating fiber increases, and promptly so-called fiber loss increases.If such fiber loss increases, the fibre weight that constitutes the textile strand that generates can reduce certainly, so the intensity step-down of textile strand.In addition, because the axial flow composition of swirling eddy is strong excessively, core fibre is many, the few low textile strand of intensity of winding fiber so generate.
Fig. 8 has represented the experimental result of the relation of the intensity (gram/spy) of the textile strand that generates and above-mentioned discharge area (square millimeter).
The textile strand of the textile strand intensity of the practicality that purposes is wider in order to generate, 10 gram/spies are above, the discharge area of space S is preferably roughly at 10～42 square millimeters.If discharge area is less than 10 square millimeters, then as mentioned above, swirling eddy is to mobile being blocked of air chamber 23 directions, the axial flow composition is extremely low, perhaps, the swirling eddy reverse flow, therefore, near the attraction air-flow that produces the inlet of the fiber entrance hole 14a of preliminary roller 6 sides of knitting needle frame 14 is to the attraction step-down to the fiber entrance hole 14a of knitting needle frame 14 direction of fiber bundle F, the intensity step-down of textile strand or can not generate textile strand, perhaps, the rotation composition of swirling eddy is strong excessively, generates the low textile strand of intensity.If discharge area is above 42 square millimeters, then as mentioned above, the axial flow composition of swirling eddy is excessive, swirling eddy is strong excessively to the flow of downstream side, fiber loss increases, the intensity step-down of textile strand, perhaps, the axial flow composition of swirling eddy is strong excessively, and the generation core fibre is many, the few low textile strand of intensity of winding fiber.
The 2nd 21c of circular cone shape portion that constitutes hollow guide shaft body 21 had better not be arranged in the through hole 24 that is arranged in jet element 15, that is, preferably have only the 1st 21b of circular cone shape portion to be arranged in the through hole 24 that is arranged in jet element 15.Because the bus of the 2nd 21c of circular cone shape portion and the angle theta 4 of centre line L 2, the bus of ratio the 1st 21b of circular cone shape portion and the angle theta 5 of centre line L 2 are big, in other words, because the outer peripheral face of the 2nd 21c of circular cone shape portion is expanded more laterally than the outer peripheral face of the 1st 21b of circular cone shape portion, if therefore the 2nd 21c of circular cone shape portion is arranged in the through hole 24 that is arranged in jet element 15, then the discharge area of space S can become too small.
Owing to the top roll 6a that constitutes preliminary roller 6 and physical characteristic that the gap W3 between lower roll 6b and the knitting needle frame 14 influences textile strand and weaving property, so must make the size of this gap W3 suitable.Though in the space 26 of the top roll 6a that constitutes preliminary roller 6 and lower roll 6b and the approximate triangle column of knitting needle frame 14 formation, along with air-flow is followed in the rotation generation of top roll 6a that constitutes preliminary roller 6 and lower roll 6b, but this follows air-flow can not be enclosed in the above-mentioned space 26, and must suitably discharge from top roll 6a and the gap W3 between the knitting needle frame 14 that constitutes preliminary roller 6.
If it is too small to constitute the top roll 6a and the gap W3 between lower roll 6b and the knitting needle frame 14 of preliminary roller 6, then the air-flow of following along with top roll 6a and lower roll 6b rotation is closed in the space 26, it is disorderly to follow air-flow to produce, the interior fiber bundle F of fiber entrance hole 14a that is imported into knitting needle frame 14 is disarrayed the uniformity of the textile strand of generation and intensity and degraded appearance.And, if it is too small to constitute the top roll 6a and the gap W3 between lower roll 6b and the knitting needle frame 14 of preliminary roller 6, then constituting the fiber f of the fiber bundle F of discharging from preliminary roller 6 and field trash etc. is blocked in the W3 of this gap, follow the discharge area of air-flow blocked, perhaps because discharge area is blocked, the field trash that enters later etc. enters weaving in the p1 of chamber etc., produces and above-mentioned same problem.
And, if it is excessive to constitute the top roll 6a and the gap W3 between lower roll 6b and the knitting needle frame 14 of preliminary roller 6, then because the top roll 6a of formation preliminary roller 6 and the bite between the lower roll 6b 27 are long to the distance of the inlet 21a1 of the hollow channel 21a of hollow guide shaft body 21, be clamped on the bite 27 and arrive the inlet 21a1 of the hollow channel 21a of hollow guide shaft body 21, the qualification fiber that the two ends of fiber are being limited simultaneously reduces, the two ends of fiber do not have confined free-fiber to increase.Because the two ends of this free-fiber are not limited, therefore be subjected to the above-mentioned influence of following air-flow easily, not only the physical characteristic of the textile strand of Sheng Chenging, particularly intensity are low, and also variation of outward appearance.And, if it is excessive to constitute the top roll 6a and the gap W3 between lower roll 6b and the knitting needle frame 14 of preliminary roller 6, the fiber f that then constitutes the fiber bundle F of discharging from preliminary roller 6 is subjected to being configured in the influence of attraction air flow of the attraction mouth C1 of the dust catcher C the lower roll 6b that constitutes preliminary roller 6 near easily, bring influence for the traveling of fiber bundle F, bring harmful effect for the importing of fiber bundle F in Ministry of Textile Industry P.Therefore, not only particularly intensity is low for the physical characteristic of the textile strand of Sheng Chenging, and also variation of outward appearance.
Fig. 9 has represented the experimental result of the relation of the top roll 6a of the intensity (gram/spy) of the textile strand that generates and formation preliminary roller 6 and gap W3 between lower roll 6b and the knitting needle frame 14.
The textile strand of the intensity of the good textile strand that purposes is wider in order to generate, 10 gram/spies are above, the top roll 6a and the gap W3 between lower roll 6b and the knitting needle frame 14 that constitute preliminary roller 6 are preferably in about below 2.3 millimeters.
The top roll 6a of formation preliminary roller 6 and the gap W3 between lower roll 6b and the knitting needle frame 14 are preferably roughly in 0.3～2.3 millimeter scope.If the top roll 6a of formation preliminary roller 6 and the gap W3 between lower roll 6b and the knitting needle frame 14 are less than 0.3 millimeter, then as mentioned above, follow the air-flow of following of top roll 6a and lower roll 6b rotation to be closed in the space 26, it is disorderly to follow air-flow to produce, the interior fiber bundle F of fiber entrance hole 14a that is imported into knitting needle frame 14 is disarrayed, the not only uniformity of the textile strand of Sheng Chenging, intensity and degraded appearance, and fiber and field trash etc. are blocked in the W3 of this gap, follow the discharge area of air-flow blocked, produce and above-mentioned same problem.If the top roll 6a of formation preliminary roller 6 and the gap W3 between lower roll 6b and the knitting needle frame 14 are above 2.3 millimeters, then as mentioned above, followed the free-fiber of airflow influence to increase easily, not only particularly intensity is low for the physical characteristic of the textile strand of Sheng Chenging, and also variation of outward appearance; In addition, the fiber f that constitutes fiber bundle F is subject to be configured near the influence of the attraction air-flow of the dust catcher C the lower roll 6b that constitutes preliminary roller 6, and therefore, with above-mentioned same, not only particularly intensity is low for the physical characteristic of the textile strand of Sheng Chenging, and also variation of outward appearance.
As mentioned above, be arranged in the air jet hole 15a in the jet element 15 outlet 15a1 pact half be positioned on the internal perisporium face 15e of the jet element 15 that constitutes cylindric spatial portion 24a, and remaining pact half be positioned at from the lower end of the internal perisporium face 15e of the jet element 15 that constitutes cylindric spatial portion 24a and enlarge on the internal perisporium face 15b that is inclined to horn-like, as to constitute the 1st circular cone shape spatial portion 24b jet element 15.So, because the air of the ejection of the air jet hole 15a from be arranged in jet element 15 is to being positioned at the characteristic of the close gradually wall lateral deviation in below to this air flow, enlarge the internal perisporium face 15b that is inclined to horn-like, as to constitute the 1st circular cone shape spatial portion 24b jet element 15 from the air of air jet hole 15a ejection along lower end and flow, so the axial flow composition of swirling eddy increases from the internal perisporium face 15e of the jet element 15 that constitutes cylindric spatial portion 24a.Therefore, near because the attraction air-flow grow that the inlet of the fiber entrance hole 14a of preliminary roller 6 sides of knitting needle frame 14, produces, this attracts air flow that the attraction to the fiber entrance hole 14a of knitting needle frame 14 of fiber bundle F is become big, carry out effectively to the importing of fiber entrance hole 14a from the fiber bundle F that preliminary roller 6 is discharged, so not only fiber loss reduces, the intensity of the textile strand of generation becomes big, and weaving property also improves.
The invention effect
Owing to the present invention includes formation described above, so can play following effect.
Owing to set contraction flow region in the space that forms between the part in the through hole that is inserted into jet element of jet element and hollow guide shaft body, therefore can suitably adjust the rotation composition and the axial flow components in proportions of swirling eddy, so can control core fibre that constitutes textile strand and the ratio of twining fiber, produce desirable textile strand.
Because contraction flow region is formed on not and counter-rotating fiber position contacting, the fiber that therefore can prevent to reverse contacts, hinders the such situation of counter-rotating of fiber with contraction flow region.
Since make the place that is formed with contraction flow region, with the axis of jet element mutually the sectional area of the face of orthogonal roughly at 6～15 square millimeters, so can generate the textile strand that purposes is wider, the intensity of practicality is arranged.
Because on the cylindric spatial portion that is positioned at fibre bundle importing side of the through hole that the outlet of air jet hole is positioned at be arranged in jet element, the internal diameter that makes cylindric spatial portion is roughly 4～6 millimeters scope, therefore can generate and twine tight textile strand, and can generate the textile strand that intensity increases.
Since the 1st circular cone shape portion that hollow guide shaft body is not only comprised at least constitute its top ends with the 1st circular cone shape portion is connected and its outer peripheral face is expanded laterally than the outer peripheral face of the 1st circular cone shape portion the 2nd circular cone shape portion, and make the 2nd circular cone shape portion be positioned at the downstream side of contraction flow region, therefore not only can suitably adjust the rotation composition and the axial flow components in proportions of swirling eddy by contraction flow region, and needn't form space between jet element and the hollow guide shaft body too much by the 2nd circular cone shape portion.
Since the 1st circular cone shape portion that hollow guide shaft body is not only comprised at least constitute its top ends with the 1st circular cone shape portion is connected and its outer peripheral face is expanded laterally than the outer peripheral face of the 1st circular cone shape portion the 2nd circular cone shape portion, and have only the 1st circular cone shape portion to be positioned at the through hole of jet element, therefore can not damage the what is called of the contraction flow region that forms in the space and can suitably adjust the rotation composition of swirling eddy and the action effect of axial flow components in proportions.
Because the external diameter on top that makes hollow guide shaft body is roughly 2.4～3.9 millimeters scope, so near produce the inlet of the fiber entrance hole of the preliminary roller side of knitting needle frame attraction air flow is become lowly to the attraction to the fiber entrance hole of knitting needle frame of fibre bundle, can generate the textile strand that intensity increases.
Owing to be not subjected near the influence of the attraction air flow the attraction mouth of dust catcher to constitute gap between preliminary roller and the fiber importing member like that according to the traveling of the fibre bundle that imports the fiber entrance hole, therefore the intensity of the textile strand that not only generates increases, and outward appearance is better.
Owing to import the gap that has formed the discharge region of following air-flow of preliminary roller between the member at preliminary roller and fiber, therefore can prevent to follow air-flow produce disorderly, import that fiber imports that the interior fibre bundle of the fiber entrance hole of member is at random, the uniformity of the textile strand of generation and intensity and outward appearance be low.
Because what make preliminary roller imports the gap of position of member in 0.3～2.3 millimeter scope near fiber, that therefore follows the preliminary roller rotation follows air-flow not disorderly, fibre bundle in the fiber entrance hole that fiber imports member is at random, the uniformity and the intensity and the low such situation of outward appearance of the textile strand that generates so not only can prevent from more effectively to import, and can prevent the such situation of discharge region that fiber and field trash etc. are blocked in this gap in, air-flow is followed in obstruction more effectively.
