Description
Usually spinning all is with RING SPINNING or open-end spinning, though it is fine with the yarn quality that these methods obtain, but be subjected to certain restriction, therefore technology is also complicated, as the open-end spinning system other character such as the bending modulus of the fiber number in the length of short fiber, spinner velocity, twist direction, wrapper fibre, the unit cross-sectional area, fiber, stiffness is all had certain limitation.The present invention can reduce a series of restrictions that open-end spinning brings provides a kind of special apparatus and method.Making in this way can be simply and produce spun yarn easily.The spun yarn and the conventional spinning method of producing with the present invention compare, and have some different outward appearances and architectural feature, exactly are the outward appearances with spun yarn.
Basic device of the present invention comprises a hollow shaft, and it is drilled that the axle surface has a part at least.Axle rotates around its axle center and is consistent with the fiber movement direction that remains to be spun into spun yarn.Fiber is in first end feeding of hollow shaft, second end of hollow shaft output from then on.Axle can rotate at a high speed.The free end that vacuumizes with fiber in to axle in the outside of axle provides suction.Vacuum is passed through clamshell internal suction air, and impels the fiber rotation in the axle.
Spun yarn by this patent production can be made raw material with various types of fibers, as cotton, polyester, viscose glue, acrylic, wool, mohair etc.Spinning process does not resemble bending modulus and the stiffness that depends on combined filament traditional open-end spinning.This patent can the unit of spinning cross section in the less open-end spinning type spun yarn of number of fiber, and this yarn has the real twist, no matter be that " Z " twists with the fingers or " S " twists with the fingers, the restriction of open-end spinning type spun yarn of the present invention aspect terminal use can not be compared with traditional open-end spinning spun yarn, but may be close with ring spun yarn.
By one of method of the present invention, spun yarn can spin through following steps: (a) draw ginning bar or rove so that loose the appearing of some fiber in rove or sliver; (b) sliver or the rove that clamp are carried with a substantially invariable linear velocity by straight line A direction; (c) after clamping, long filament fed in rove or the sliver go, so the core silk also can the A direction identical with sliver that clamps or rove pass through; (d) when when the A direction is carried sliver or rove and core silk, make fiber loose end rotation around staple fibre and tow, during rotation, these loose ends remain unchanged substantially in rectilinear direction, the spun yarn that has the core silk that the result just obtains requiring.The core silk is preferably selected the elater that adds of full drawing-off for use.Be preferably in when carrying yarn is applied tension force, it is pulled through on the sharp edge of a non-conducting material, remove tension force then and form curling.
By two of method of the present invention, the step (a) identical with method one and (b) can be provided, and comprise that following additional step (c) incorporates a long filament of controlling certain overfeeding into clamping sliver or rove that the A direction moves at the B point; (d) B point and then, the loose end of rotation sliver and yarn makes it to remain unchanged substantially by rectilinear direction when rotated, lives core silk or other fiber with looping, obtains having the spun yarn of circle or tubercle effect at last.
By other method of the present invention, except that step (a) and (b) constant, further comprising the steps of: as (c) long filament to be imported on straight line A direction with the sliver of clamping or rove and merged, meanwhile long filament is applied certain tension force and make in the long filament about 20% fibrous fracture.(d) when at A when conveying has the sliver of broken fiber or rove, the loose end of rotation fiber and to broken fiber effect makes its looping around the sliver of clamping and rove, broken fiber and clamping sliver or rove interact, the spun yarn that obtains having the staple fibre outward appearance at last.
It is described to press this patent, and another kind of method can also be provided.The method comprises: (a) sliver or rove are drawn to roll to make the generation loose fiber, therefore, almost all basically fibers all are to have staple length and free-ended fiber, (b) fiber is transmitted with essentially identical linear velocity by rectilinear direction A, (c) when transmitting fiber, make the loose end rotation form core with the fiber that about 20-40% is provided.This core has the real twist, and the fibre bag of nearly 80-60% is entangled in around the core so that skin effect to be provided, and makes its outward appearance similar with the spun yarn of fully twisting.The spun yarn and the full twist yarn of getting along well by this program spinning are similar.
Main purpose of the present invention provides a kind of simple, effective spun yarn production method, and this purpose of the present invention and other purpose can obtain clear and definite understanding by detailed introduction of the present invention and explanation and appended claim.

Below introduce in detail each figure:
By the present invention, two kinds of equipment that are used to produce vacuum spinning are arranged, this is illustrated in Fig. 1 and Fig. 6, and respectively by total reference number 10 and 12 marks.Equipment 10 is used to produce the yarn identical with traditional ring spinning, and equipment 12 then is used to produce airflow spinning, and this spun yarn was both similar to the yarn that traditional RING SPINNING obtains, again the yarn that obtains similar in appearance to open-end spinning.The critical piece of system 10,12 is a vacuum spinning equipment 14, and Fig. 2 and Fig. 3 have the most clearly illustrated this equipment.
Equipment 14 comprises its major part-quill shaft 15.It is drilled having a part of periphery on the quill shaft 15 at least.The core that is preferably in axle is drilled with a plurality of holes 16, and quill shaft is erected can be around the rotation of its axle center, and it is consistent that this axle center and the fiber straight line that remains to be processed into spun yarn feed direction A.The axle size should be selected like this, must guarantee that promptly fiber passes through therein, and allow enough air take out of and allow with fiber fiber by vacuum suction on its inner surface 17.
The cores of axle 15 punchings by 19 of valve jackets around.Quill shaft can be by the bearing transmission that links to each other with valve jacket outer wall 20,21 around the rotation in its axle center.Or provide by the bearing 22,23 that supports from outer wall 20,21 outward extending quill shaft outer ends.After installing, axle 15 can rotate freely.
In order to make fiber enter the hollow cavity of axle 15, need reaching axle 15 external suction vacuum in the valve jacket 19.Be preferably in valve jacket 19 inwall parts and adorn a vacuum pipeline 27, conduit and conventional vacuum source 28(such as vavuum pump) link to each other, what be connected is the conduit 29 that is connected with surrounding air or other source of the gas with the inwall of the valve jacket 19 that faces conduit 27 right opposite of axle 15 (promptly).
Continuous (the preferably integral body) of axle is many blades 31 that radially extend therewith.These blades 31 extend to just in time the radius less than valve jacket 19 inwalls.When conduit 27 was vacuumized, air promoted blade 31 and makes axle 15 rotations promptly by conduit 29, and air is discharged from conduit 27 then.At this moment, air also passes from the inner surface of axle 15, and fiber is adsorbed on the inner surface 17 of axle 15.According to the said structure arrangement of Fig. 3, rotation certainly, also can change structure arrangement and make direction of rotation just in time opposite in the direction of arrow B.
Equipment 14 provides a kind of simple, effective structure of producing spun yarn.This is simple in structure and for ease of maintenaince, can stablize rotation at a high speed, and can adopt in light weight, durable material manufacturing.
What be connected with vacuum spinning equipment 14 and equipment 10 is drafting system, in Fig. 1, does simple explanation by label 33.Sliver or rove 5 are pulled out 35,36,37 through feeding roller from silk tube 34, and preceding yarn feeding roller should be consistent with the axis of rotation of axle 15 to 38 the folder center of rolling.The fiber that drafting system 33 acts on sliver or rove 5 is rolled tightly the fiber of about 75-95% in the sliver, and the remaining approximately fiber of 20-10% has loose end.
A pair of transmission roller 40 is by the opposite of frame at equipment 14, as drafting system 33, roller to 40 Clamping Center also must adjust to axle 15 to revolve the axle center consistent.Transmit roller and to 40 the yarn Y that forms is pulled out from equipment 14, last yarn Y can be reeled by the Wound-up roller device 41 of routine.
When fiber was admitted to the inner chamber of quill shaft 15, the loose of fiber appeared by vacuum draw to inner surface 17, and fibre bundle then transmits along rectilinear direction A.The fiber that is adsorbed in surface of internal cavity 17 appear when they during with axle 15 rotations, remain unchanged substantially in rectilinear direction, therefore, like this some fibre just be wrapped in main fiber beam around.Fibre bundle whenever passed through axle at 1 o'clock, and axle 15 is rotation 1.5-6.0rpm approximately.Like this, just can obtain enough loopings, and make the intensity of yarn reach requirement.
Yarns Y by Fig. 1 to Fig. 3 spinning apparatus of the present invention can schematically be illustrated by Fig. 5 a.This yarn is compared with the yarn of conventional RING SPINNING shown in Figure 4.The yarn of Fig. 4 has must hair shape outward appearance.All add sth. made by twisting on the whole yarn diameter.Yet the yarn of the present invention spinning has then comprised a center fiber bundle 45, and the rectilinear direction looping some fibre 46 and other have the fiber 47 of reverse plying looping.
If be necessary, yarns Y can be by steam treatment with typing wrapper fibre 46,47.This can be before roller 41 be reeled, and allows the decatizing apparatus 48 of yarn through a routine.Perhaps also the decatize process can be used as a diverse step carries out after reeling.
The fabric made from yarns Y (55% polyster fibre, 45% wool fibre) has dyeability very uniformly.
Device 12 leads 33 places, district at device 10 and comprises among Fig. 6: conventional combing roller 50 and boundling roller device 51.Combing roller 50 is appeared sliver or rove 5 generation fibers, and makes sliver or rove arrive boundling rollers 51 devices through air trunnion 52.The boundling roller 53 of boundling roller device 51 has more detailed description in Fig. 7, comprise an equipment that is carved with groove 54 in the above.And, be drilled with many apertures 55 in the groove 54.Boundling roller device 51 also comprises a valve jacket that does not vacuumize 57 and another vacuumized part 58.58 link to each other with vacuum source 28, thus air from the outside of roller 53 by the inside of hole 55 suction rollers 53, be extracted into vacuum source 28 through conduit 59 at last.
Fiber in trunnion 52 is brought into by the balance air flow.Air enters air drawn device 60, is extracted into vacuum source 28 by roller 53 and eyelet 55 equally.Therefore the fiber in air trunnion 52 generally is parallel.Typical staple length is 1/2-1/6 o'clock, and fiber is collected on the roller 53 side by side, and the fibrage of generation depends on the speed of roller 53.About 3/8 of roller 53 leads to vacuum source 28, and other 5/8 does not then vacuumize.Fiber is earlier through roller 53 shreddings of roller device 51 upper ends, and then, because vacuum has been taken out in the inside of the valve jacket 19 of vacuum spinning equipment 14, fiber is admitted to air trunnion 62.
When the loose fiber bundle enters the hollow cavity of axle 15 by air trunnion 62, just be adsorbed on the inner surface 17 of axle 15, when transmitting by straight line A direction, fiber is rotated.These fibers have been controlled in this rotation fully, so the sort of winding that they do not exist in the open-end spinning of routine.But also production yarns Y '.Fibre bundle or core 45 ' (seeing Figure 56) has the real twist, these twist with the fingers both desirable " Z " to, also desirable " S " to.Typical fibre bundle or heart yarn comprise the fiber of 20-40%, the fiber of 80-60% then become wrapper fibre 47 '.Yarns Y ' have extremely effectively skin effect, its outward appearance is similar to full twist yarn.Yarns Y ' pull out from equipment 14 by transmitting roller 38, then by traditional clip type or groove-shaped Wound-up roller 64 coiled bobbins 65.Yarns Y ' can produce with various fibers.Other performance of bending modulus, stiffness and fiber can not resemble has certain limitation traditional open-end spinning.The less yarn of fiber in yarns Y ' also can the be spun into unit are.
Yarns Y ' also can spin through the 4 inch combing rollers that are fixed between the roller 38,40 by staple fibre (cotton/polyster fibres) such as 1 1/2.Equally, the fiber of nearly 20-40% forms core 45, and approximately the fibre bag of 80-60% is entangled in the core outside so that skin effect to be provided.The outward appearance of this kind yarn is similar to the outward appearance of full twist yarn.For example, for the Y ' of yarn shown in Figure 56, outer wrapper fibre 47 ' in every inch have 10 " Z " and twist with the fingers, and heart yarn 45 ' in every inch also have 10 " Z " and twist with the fingers.But, must be noted that the fiber number that converts heart yarn to is variable to the ratio of wrapper fibre number.This is determined by following factor: process is fixed on roller 38 and 40 staple length, vacuum and nozzle arrangements, nozzle rotary speed and orifice size, and spinning speed and fiber properties are such as rigidity, frictional behaviour, diameter or the like.
Preferable vacuum spinning equipment 114 is shown in Fig. 8 a and 8b.Wherein major part comprises the quill shaft 150 of a prolongation, and first end (entrance point) on it is designated as 151, the second ends (port of export) and is designated as 152.Bore passages in the axle 150, its first is designated as 153, and second portion is designated as 154, extends to second end 152 from first end 151 always.The whole circumference surface of axle 150 has at least a part to punch.Preferably these holes are broken into four porose areas of the outer garden side face that is evenly distributed on axle 150, in Fig. 8 a, be designated as 155-157.On the same fortunately plane P of these Kongzuis, P is perpendicular to the axis of rotation A-A of axle 150, and these Kongzuis are good from hollow cavity 153 tilt to the direction of second end (especially can referring to Fig. 8 a mesopore 155,157).Hole 155-157 is in an acute angle with axle A-A, and the air that such arrangement can allow to suck hollow cavity 153 by vacuum source 160 flows into vacuum source 160 from the outside of axle 150 more equably.So just can make the yarn of spinning meet the requirements of performance.
Eyelet 155-157 also can beat along the other parts of axle on 150 length, and number is not necessarily four (that is, can be more, but had better not be less than 3) also, at the position of first end 151 that closes on axle 150 punching 155-157, also can meet the requirements of the result.
Axle has a vacuum chamber 162 in 150, and vacuum chamber 162 as shown in the figure comprises that a diameter is approximately the spherical chamber of 2 times of the diameters of cavity path 153, communicates with hollow cavity passage 153 154 at its two, and on its circumference, then communicates with eyelet 155-157.It is spherical that vacuum chamber is not necessarily wanted, though this is more rational configuration.Another kind of desirable configuration is that the one end is spherical cylindrical or similar configuration.The effect of vacuum chamber is that air flow can evenly be flowed in axle 150, makes fiber appear looping better with spinning high-quality yarn at last.
In order more effectively to realize the looping effect, require to have a diffuser 164.Diffuser 164 comprises that a sleeve pipe or collar are contained on the excircle of axle 150.Be preferably between the inner surface 166 of collar 164 and axle 150 the excircle 167 annulus 165 is provided, include some long slits on the collar 164, slit extends towards axle center A-A.Preferably each slit links to each other with eyelet 155-157, for example sees the slit 169 and 170 among Fig. 8 a, and they link to each other with 157 with eyelet 155 respectively, and 171 among Fig. 8 b.These slits (such as 169,170) and space 165 help to provide the air flow of requirement.
Collar 164 preferably is installed on the axle 150, can change the arrangement between slit (as 169-170) and the hole 155-157 like this, as collar 164 is installed, first end surfaces 174 is linked to each other with the surface 175 of axle 150, and the surface 177 of second end surfaces 176 and the raising of axle 150 links to each other, on surface 174,175 and 176, a CONTACT WITH FRICTION is arranged between 177, but this CONTACT WITH FRICTION can be even as big as not stoping relatively rotating between collar 164 and the axle 150, tighten owing to collar 164 usefulness hands or with instrument, rotation is achieved like this.Because slit (as 169-170) and hole 155-157 align-err, " effect " will have influence on yarn Y.
Roller is to 38,40 2 parts are in order to allow textile fabric enter and to pass through 153,154 channel part, best roller 38,40 bite wants mutual one to also being consistent with an axle A-A, and these two pairs of rollers also provide by dress axle 150, make it to rotate around axle center A-A, and make it can be continuous, high speed rotating relatively.
Preferably include the bearing assembly of connection first and second ends 151,152 for the installation component of turning cylinder 50.Be centered around axle 150 first end 151 as clutch shaft bearing assembly 180, between the antetheca 181 of it and the inaccessiable garden of an air barrel shell cover 182, provide to relatively rotate.And second end 152 that second bearing 183 is installed near axle 150 makes it to relatively rotate between the rear wall 184 of axle 150 and clamshell 182.Clamshell 182 is preferably transparent, and bearing 180,183 can be any medium-sized, only otherwise allow more air stream pass through, just can not have the oil running, or because other danger that air flow causes.Clamshell 182 can be fixed on the desk, or on other structures that fix on the ground.
Axle 150 is to rotate by the axle of motor by belt and belt pulley transmission.Belt pulley 192 is preferably formed an integral body with axle 150, and the shaft of another belt pulley and motor is formed one.Motor is with constant desirable speed drive axle 150, and this speed can change along with the variation of motor speed.
Fig. 9 shows a kind of device that core spins that is used for, and the structure of this concrete equipment and the device structure of Fig. 1 have illustrated in more in front the reference number " 2 ".The vacuum spinning device preferably is used in Fig. 8 a, the device 114 shown in the 8b.In this concrete equipment, heart yarn C by one group of roller 70 feed roller 238 also and sliver or rove S together move along rectilinear direction A.If be necessary, usually add a power on yarn C in the A direction, make about 20% core fibre C fracture, this can be at roller 240, adding one between 238 gives pulling force and finishes, the fiber of these fractures just forms short yarn fiber in the internal action of vacuum spinning device 114, thereby produces a kind of yarn YY of imitative short yarn outward appearance.
Figure 10 and the another kind of typical core-spun yarn device of 11 explanations, curling in this concrete equipment forms on heart yarn, so that provide the effect of entwining of good inside between the sliver of core fibre and clamping or rove S.
Add with reference to Figure 10 and 11, full drawing-offs and to play yarn CC and send here, and between roller is to 73,74, keep certain force of strain by feeding yarn 72, between roller is to 73,74 by sharp (as a plastic sheet) making by non-conducting material.After yarn CC is by sharp, between roller 74 and 338, removes tension force, thereby form curl (Figure 10, the structure of 11 concrete equipment and the equipment of Fig. 1 have illustrated more) in above-mentioned reference number " 3 ".This stage of curling into causes yarn CC single fiber to repel each other each other (seeing Figure 11) and forms a thick loose fiber that separates, and when the fiber that separates on the yarn CC mixes with the sliver fiber S that clamps, just provides the effect of entwining of good inside.When this fiber enters when removing vacuum spinning in the vacuum spinning device 114, just generated a kind of special yarn YYY.This YYY yarn has 100% short fiber and adds the top performance that plays yarn, in the yarn outside that generates a large amount of short fibers is arranged.The manufacturing of typical case's yarn is as follows:
