Apparatus for performing the invention is also disclosed.
Description
What the present invention relates to is open-end-spinning with the high-speed production textile yarn, and improve yarn qualities with this, wherein, staple fibre in air flow (as single fiber) is sent to fiber bundling zone from the fibre-opening unit having of fiber, be incorporated into the afterbody that freely rotates of the yarn that forms at this fiber, fibre bundle is twisted to form yarn then.
Require to form fibre bundle and go up twisting simultaneously mutually in identical operations because understanding goes up, this has hindered the development that is generally used in the previous friction spinning of producing textile yarn.The notion of general friction spinning is the fiber that produces the screw orientation structure, rather than stretching with parallel fiber.In fact also have skidding to appear between fibre bundle and the friction surface, this be since between friction surface the result in wide slit, and this gap is that to adapt to the double factor of fibre bundle and twisting necessary.This spirality fiber bundle and lack the reliable control that fibre bundle is applied twisting, the result has formed the low powerful yarn with different twist rates.
In other some friction spun yarn systems, the production of yarn has had similar difficulty, even when fibril aggregation and twisting separate, as system in, equipment can not guarantee that the rotation of the yarn that forming is maintained to its afterbody tip under free-ended state, and can not guarantee that such rotation is roughly synchronous with the added sth. made by twisting of rubbing surface, also have the same problem of this low powerful yarn and the different twists in the known air vortex spinning.
These problems that presented in the production are described in German patent application DE.3348045.0, this patent is attempted fibre transportation to a wide funnel shaped air chamber that spins, this air chamber is equipped with a series of compressed-air atomizer to produce the eddy current air that a kind of narrow end towards funnel increases peripheral speed gradually, at this air exhaust duct is arranged, it also can be used as the spinning pipe, and it is connected to a source of suction.The fiber entrained by the air flow that flows out obtained by the afterbody of formed yarn on blast pipe, and fiber must be to twine around the version of the yarn that is forming towards the increase of blast pipe direction along with eddy velocity, have the shaping yarn that twines fiber from blast pipe pull out by the funnel eddy current be incorporated into one with the axially aligned extraction tube of blast pipe, in this extraction tube, be provided with an additional twisting apparatus.
In such device can not to its free end of the yarn afterbody introduced by eddy current increase the twist, the rotational synchronization of the rotation that also can not make the free thread end afterbody and additional twisting apparatus.Therefore be false twisting by what add the twisting generation, so the straight sth. made by twisting of final yarns will depend on the different twists that are introduced on the yarn afterbody, like this, above-mentioned formed yarn will be low intensive.In addition, add true sth. made by twisting degree can not add up by the velocity of rotation that the twisting apparatus of yarn afterbody has been introduced in increase, consequently can not realize the high-quality yarn of high-speed production.
The application is to be solved to be above-mentioned problem and at open-end spinning device, comprises the restriction of being met in the practice of known friction spinning apparatus.
The objective of the invention is to provide by the Free-end Friction Yarn spinning technique a kind of method of formation fibre bundle of the yarn that is used to be shaped, it overcomes or reduces above-mentioned problem, and can realize high production speed and high-quality, and has the gratifying introducing twist.
According to this purpose, provide a kind of method that is used for by the fibre bundle of the open-end-spinning of twisting apparatus at this, comprise the aggregation zone that the air that is carrying fiber is input to a qualification, on this aggregation zone, keep a kind of circumference air flow around the air that carries fiber, described circumference air flow is a kind of pressure that is used for the radial compression fibre bundle in aggregation zone, and on the desired direction of final yarns twisting, control to adjust by twisting apparatus, the axial direction that air is introduced with fiber from described aggregation zone is extracted out then, and formed fibre bundle on the aggregation zone with this axially relative direction on extract out and be transported to twisting apparatus.
Usually, aggregation zone is made of an interior cylindrical surface, air flow is to enter aggregation zone with the tangent direction of described drum surface basically, the fiber that is loaded with air that axially enters aggregation zone by the air of circular motion around its rotation and compression radially, so that by air contained fiber and the afterbody that enters into the shaping yarn of aggregation zone, basically the periphery with formed aggregation zone does not come in contact, and its aggregation zone is fixed.Like this, for having true free-ended shaping yarn, continuous accumulation shaped fibers and extraction fibre bundle are possible.
The pressure of ring-type air is compressing the fiber that is loaded with air flow, impels on the afterbody that is attached to the shaping yarn of fiber with this, and prevents the fiber waste of dispersing, and helps the rotation as " free end " shaping yarn afterbody simultaneously.The air conveying fiber is to aggregation zone, throws off the free-ended fiber air that has been attached to the afterbody that is rotating and then arrives a source of suction of aggregation zone far-end with pressure air.Moving air stream on the relative direction of extracting out with fibre bundle applies a useful axial tensile force to its fibre bundle, to keep fiber stretching, helps the tensile strength of yarn thus.
The fiber of initial preparation is at a general fibre fibre-opening unit having, for example a kind of separator, and this fiber is carried in the air flow then, for example by a conduit, and enters into fiber bundling zone.
Fibre bundle can axially be incorporated in the friction spinning apparatus, for example at Australian Patent AU501999, or the friction spinning apparatus described in the U.S. Pat 4091605, can be at this in conjunction with above-mentioned each piece patent of reference.
Usually, the axle of fiber bundling zone is and the rectangular equipment of the rotational plane of friction twisting member therefore, to consider from the space, conveying be loaded with fiber air conduit can with the rectangular setting of passage that limits accumulation regions, or more not convenient be receding with an acute angle.In these structures, be subjected to a suddenly bigger direction change in order to enter fiber bundling zone air flow and fiber, this just produces adverse influence to air and fibre stream, causes the character that produces disorder and influence the fiber pack.Can not make fiber feeding pipe and aggregation zone passage more straightly in line, so that fibre stream can not interrupt sharp from normal route, because the position on pivoting friction surface, effect and characteristic are restricted this design and structure.
In addition, the good operation of free end system requires the rotation of its fibre bundle not hindered, and is that afterbody is short, and fiber bundling zone is near the inlet of the fibre bundle between the pivoting friction surface.Otherwise fibre bundle produces disadvantageous shake, and this for the stable rotation of fibre bundle of concentrating that is required by the friction surface effect to give negates.
According to a further aspect in the invention, it provides a kind of method of being carried out open-end-spinning by fiber, the step that it comprises is, fiber is carried in the air flow, the fibre transportation that is carried is arrived the fibril aggregation district, fiber on the described aggregation zone is attached to the fibre bundle afterbody that is rotating, afterbody is extracted out to flow in the fiber bundling zone opposite direction with air in company with the fiber from aggregation zone attached thereto, and between two rotating surfaces of fibre bundle by rotation, and with each the surface contact, twist thus and form yarn, it is characterized in that described fiber bundling zone is to be positioned at a catheter interior, this conduit has one and the straight axis of passage between described two friction surfaces, and tilt with its rotational plane, described fiber is transported to described fibril aggregation conduit between aggregation zone and rotating surface, and has an angle that is not less than 90 ° to be transported to described fibril aggregation conduit with the axis of the fibril aggregation catheter downstream that is connected with the fibril aggregation conduit.
Usually, fiber is transported to the fibril aggregation conduit along a passage, and this passage is arranged essentially parallel to the common plane of each the member rotation that constitutes rubbing surface.Be preferably rotating surface and relatively do identical inclination with turning cylinder separately, and they are installed make and form the gap between them.After leaving aggregation zone, by this gap, fibre bundle is pulled, and contacts with each friction surface.Provide the member of friction surface on relative direction, to be rotated thereon with identical peripheral speed, so, fibre bundle is by its " clamping zone ", and should " clamping zone " remains on the fixed position becoming with fibril aggregation conduit axis on the axial straight line.
In the former Free-end Friction Yarn spinning apparatus, wherein fibre bundle is to pull out by a gap between two pivoting friction surfaces, it exists two opposite frictional force, a frictional force is in a circumferential direction, fiber is produced afterturn or twisting to form yarn, and another frictional force is in the axial direction, and it is produced by the gap that fibre bundle is pulled through between two friction surfaces.Axial friction is being produced a tension force on the fibre bundle of twisting, it can cause the yarn broken string, thereby reduces reliability and speed of production.
These problems can be used the friction surface of taper and be reduced widely, and by the gap that the conical friction face is limited, fibre bundle is pulled, and fibre bundle is entered in the gap in the smaller diameter end of its conical surface, and come out than larger diameter end from it.
Because the result of this structure, and due to the fact that, the member that forms friction surface on it is in the opposite direction to be driven with same velocity of rotation, thus at the arrival end in gap on the length of the port of export, the superficial velocity of friction surface is from more slowly to comparatively fast increasing gradually.Because conical surface, frictionally act on the side of shaping yarn, axial rub between fibre bundle and friction surface advantageously is used for strengthening and simplifying the extraction of fibre bundle by the screw propulsion effect, the influence of its screw propulsion is by superficial velocity increasing and produce to the coupling of bigger end than small end from the circular cone friction surface.
Below in conjunction with the accompanying drawing embodiment that present invention will be further described, wherein:
Fig. 1 is the schematic diagram with the method for fiber spun yarn;
Fig. 2 is an axial section schematic diagram of fibril aggregation device and friction twisting device;
Fig. 3 is the generalized section that 3-3 along the line is cutd open among Fig. 2.
Now referring to Fig. 1, a kind of ribbon 1 is fed in the suitable separator 2, this fiber from cellucotton, separated seriatim and input air stream, known have various separators commonly used to can be used for above-mentioned purpose, and the feeding speed of ribbon then can come in known manner to be controlled according to the specific (special) requirements of fiber, desired one-tenth yarn count and the spinning proportion of goods damageds of estimating.
Fiber through separator 2 is crossed conduit 3 and is entered into fibril aggregation device 4 with air communication.The fibril aggregation device is a major part of the present invention, will be described in further detail in the back, and air is extracted out by source of suction 7 through conduit 5 from collector.And fibre bundle is drawn engaging friction twister 8 from collector 4, and the yarn after the twisting is drawn from twister 8 by withdrawal roller 11, is sent to yarn then and receives spool 12.
Now referring to Fig. 2, the defibre entrained by air outputs to fibril aggregation device 4 by conduit 3 by separator shown in Figure 1, its collector comprises tubular articles 17, it defines columnar concentrated fiber bundling zone 16, and form opening in each end 20 and 21, openend 20 is communicated with getter device 7 shown in Figure 1, and openend 21 is communicated with fibre transportation conduit 3, and conduit is transported to aggregation zone to fiber from separator.
For provide a smooth transition surface change fiber from conduit 3 to tubular articles 17 flow direction, the shield 18 of moulding is located on the join domain of conduit 3 and tubular articles 17.Simultaneously, baffle plate 18 prevented the fiber of introducing impact and prevent too early be attached to be transported to the fibre bundle that moves on the twisting apparatus 8 that will be further described below from collector on.
Resulting straight, parallel and fiber stratiform, and the fibre stream of protecting by boundary layer of air, along with they enter aggregation zone 16, the result is that most of fiber presents a kind of circle, its similar a kind of hollow disconnected warp thread.
It is not shown that continuous cavity 25 is provided at fiber bundling zone 16() periphery of going up tubular articles 17, fiber bundling zone 16 is connected with compressed air source through passage 26, cavity 25 is seen Fig. 2 illustration " A " by some apertures or slit 28() and be connected with fiber bundling zone 16, its aperture or slit are that the inwall of relative tubular articles 17 becomes the tangential wall that passes tubular articles 17.At least two such apertures or slit 28 are arranged on the radially relative position, and are on an axial common horizontal plane of aggregation zone 16 relatively.
On fiber bundling zone 16, by being set, the air that slit 28 produces rotation flows, and cause that gathering fiber in aggregation zone 16 is around axially rotating, select the tangential situation in aperture or slit 28, so that be same as the twist direction of introducing by twisting apparatus 8 by the direction of rotation that air is passed to fibre bundle.Except producing in aggregation zone 16 above-mentioned rotary air flows, its pressure of air by aperture or slit 28 is enough in the inside direction of the wall that leaves tubular articles 17, and compresses and obtain fine and close fibre bundle towards the axis of aggregation zone 16.
The effect that this compressed air forms also provides a fiber gap between the inner surface of fibre bundle and tubular articles 17 except forming the feltwork bundle, make fibre bundle can become a free end ground and rotate.Formed these desirable free end conditions are used to form the afterbody part of yarn and are just twisting with the fingers the fiber of tying in this afterbody.
Also will be understood that, getter device 7 air from aggregation zone 16 towards tubular articles 17 openend 20 extract out, and this axial tensile force was maintained on the fiber between the accumulative phase of fiber, and favourable impelling keeps fiber stretching in the fibril aggregation process like this.
Extracted out the axially aligned openend 29 of process baffle plate 18 and enter into friction spinning apparatus or twisting apparatus 8 from the end 21 of tubular articles 17 by condensing fibre bundle, this device was for example described at the applicant's the big Li Liya patent of early stage U.S. Pat 4091605 and Australia AU501999, can be incorporated into the application at this.Baffle plate 18 axially enters into aggregation zone 16 and do not strike the condensing fiber that is being incorporated into twisting apparatus with the change direction for the fibre guide of being introduced by conduit 3 is crucial.
Now referring to a preferred construction of as shown in Figure 2 twisting apparatus 8, it comprises the fixed bearing pedestal 50 of a component part basic structure 35, and its rotating external friction ring 51 and interior drag ring 52 of supporting, external friction ring 51 rotates around axle 53, and interior drag ring 52 rotates around the axle 54 that is eccentric in axle 53.
The butt female cone surface 55 of external friction ring 51 is a kind of friction materials, rubber for example, and the outer surface 56 of interior drag ring 52 is a kind of same or similar friction materials.Set inner surface 55 and outer surface 56 are sentenced friction-driven shown in Figure 3 60 and are contacted, interior drag ring 52 is incorporated into driving wheel 58 by the axle 59 of concentric, and driving wheel can be incorporated on the suitable CD-ROM drive motor, for example an electro-motor (not shown).This drives structure can make two drag rings 51 and 52 all rotate so that conical surface with identical peripheral speed backward rotation.
58 places of fibre bundle between inside and outside drag ring pass through, with each friction surface CONTACT WITH FRICTION, so fibre bundle its axially on by afterturn, make fibre bundle is applied real sth. made by twisting.Because rotate with identical peripheral speed on two surfaces, though be to rotate in the opposite direction, the fiber of assembling will keep a reliable and constant position between two surfaces simultaneously.
More clearly be that the other drives structure can be used for driving inner and outer ring, to obtain the same peripheral velocity of each inner and outer ring, makes to keep gap 61 on the fixed position with respect to the fibre bundle that is produced by aggregation zone 16.
Learn that by Fig. 2 the end 21 of the position in gap 61 and tubular articles 17 and guide pipe 29 are extracted out from aggregation zone 16 by this gap fibre bundle in line.Also can learn, encircle thereon 51 and 52 rotating planes with respect to tubular articles 17 the axle and be tilted, and make conduit 3 to it similar be tilted of conveying fiber thus to tubular articles 17, when fiber enters tubular articles 17, provide the flat rapid transition of fiber traffic direction at this, with with fibre transportation to aggregation zone 16, need shorten the distance between aggregation zone 16 and the inlet that enters gap 61 between two pivoting frictions surperficial 55 and 56 simultaneously.
Also can be with reference to former technology, because friction surface 55 and 56 tilts separately for its corresponding rotation parallel axes, and because fibre bundle enters gap 61 with its less diameter end, when fiber during from the large diameter port of export of minor diameter upstream end by gap 61, fibre bundle is subjected to the acceleration of the peripheral speed of friction surface.
This just helps lend some impetus to fibre bundle and passes through forward through gap 61, and by lead-in wire roller 11 yarn is pulled out the required tension force that is applied on the fibre bundle by twisting apparatus 8 and also reduced.
