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.The yarn that equipment 10 is produced is similar to traditional ring spinning.Equipment 12 then is used to produce a kind of free end type spinning that has.And the performance of this yarn was both similar to traditional ring spinning, again 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.
The cores of axle 15 punchings by 19 of valve jackets around.Quill shaft can provide by the bearing that links to each other with valve jacket end wall 20,21 and/or by the bearing 22,23 that supports from end wall 20,21 outward extending quill shaft outer ends around the rotation of its axis.After installing, axle 15 can rotate freely.
Inner and the axle 15 external suction vacuum to valve jacket 19, thus act on the yarn fibers of hollow inside of axle 15.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 link to each other 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 opposite side 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, and 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, makes schematic illustration by label 33.Sliver or rove S pull out 35,36,37 through feeding roller from bar 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 S is rolled tightly the fiber of about 75-90% in the sliver, and the fiber of remaining about 25-10% has loose end.
A pair of transmission roller 40 is by the opposite of frame at equipment 14, and as drafting system 33, roller also must be adjusted to consistent with the axis of rotation of axle 15 to 40 Clamping Center.Transmit roller and to 40 the yarns Y that forms is pulled out from equipment 14, final thread 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 basic fibre bundle then transmits along rectilinear direction A.The fiber that is adsorbed in surface of internal cavity 17 is appeared, when they during with axle 15 rotation, remain unchanged substantially in rectilinear direction, therefore, like this some fibre just be wrapped in main fiber beam around.Fibre bundle is whenever by 1 inch on axle, and axle 15 is rotation 1.5-6.0rpm approximately.Like this, just can obtain enough parcels, 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's spinning comprises a center fiber bundle 45, its rectilinear direction looping some fibre 46, and other fibers 47 have 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 steaming plant 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% wash wheel fiber, 45% wool fibre) has dyeability very uniformly.
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 pressing the transmission of straight line A direction, rotates by fiber with axle 15.These fibers have been controlled in this rotation fully, so they are different with the sort of winding that exists in the open-end-spinning of routine.Produce like this yarns Y '.Fibre bundle or core 45 ' (seeing Fig. 5 b) 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 ' from equipment 14, pull out by transmitting roller 38, then by traditional clip type or groove-shaped Wound-up roller 64 around to bobbin 65.Yarns Y ' can form 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 be spinned through 4 inches combing rollers that are arranged between the roller 38,40 by staple fibre (such as 1 1/2 inches cottons/wash wheel fiber).Equally, the fiber of nearly 20-40% forms core 45 ' (the seeing Fig. 5 b) with true sth. made by twisting, approximately the fibers encapsulation of 80-60% 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,, have 10 " Z " at outer wrapper fibre 47 ' middle per inch and twist with the fingers, twist with the fingers and also have 10 " Z " at heart yarn 45 ' middle per inch for yarn Y ' shown in Fig. 5 b.But, must be noted that, the fiber number that converts heart yarn to is variable to the ratio of wrapper fibre number, and determined: with respect to staple length, vacuum pressure and the nozzle arrangements of the roller that is arranged on roller 38 and 40 by following factor, nozzle rotary speed and orifice size, spinning speed and fiber properties be rigidity, frictional behaviour, diameter or the like for example.
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 it has one first end 151 and one second end 152.Be provided with the bore passages that always extends to second end 152 from first end 151 in the axle 150, it has one first section 153 and 1 second section 154.At least a portion on the whole circumference surface of axle 150 is punched.Preferably these holes are broken into four porose areas that are evenly distributed on axle 150 outer circumference surface, at Fig. 8 a not 155-157 that gets the bid.On the same fortunately plane P of these Kongzuis, P is perpendicular to the rotation A-A of axle 150, and these Kongzuis are good from the direction inclination (especially referring to Fig. 8 a mesopore 155,157) of bore passages portion 153 to second end.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 preferably be no 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 bore passages 153, communicates with hollow cavity passage 153,154 in its two opposite end, and communicates with eyelet 155-157 along circumference.Vacuum chamber not necessarily will be sphere, though this is more rational configuration.Another kind of desirable configuration is that the end is spherical cylindrical or similar configuration.The effect of vacuum chamber is that air flow can be flowed in axle 150 better, makes fiber appear looping better with spinning high-quality yarn at last.
When use equipment 114, require near first end 151 of axle 150, to make air flow to concentrate, for this reason, also require to do the size of channel part 153 more much bigger than channel part 154.Channel part 153 extends to vacuum chamber 162 from first end 151, and part 154 then extends to second end 152 from vacuum chamber 162, as a non-limiting instance.The diameter of part 153 is 1/8 inch, and the diameter of part 154 is 1/16 inch, and the diameter of spherical vacuum chamber 162 is approximately 1/4 inch.
In order more effectively to realize the looping effect, require to have a diffuser 164.Diffuser 164 comprises the sleeve pipe or the collar that are contained on axle 150 the excircle.Be preferably between the inner surface 166 of collar 164 and axle 150 the excircle 167 annulus 165 is provided, be formed with some long slits in the collar 164, slit extends along axis A-A.Preferably every slit is connected with eyelet 155-157.For example see the slit 169 and 170 among Fig. 8 a, they link to each other with 157 with eyelet 155 respectively, and the slit 171 among Fig. 8 b.These slits (such as 169,170) and space 165 help the air flow performance that provides required, to improve the quality of yarn that use device 114 is produced.
Collar 164 preferably is installed on the axle 150, can change the arrangement of slit (as 169-170) with respect to hole 155-157 like this.As collar 164 is installed, the surface 175 of first end surfaces 174 and axle 150 is engaged, thereby the surface 177 of another raising of second end surfaces 176 and axle 150 engages, 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 when holding collar 164 with hand or instrument it is rotated collar 164 and spools 150.Because the erroneous arrangement of slit (as 169-170) and hole 155-157 will exert an influence to yarns Y.
Be used for device that installation shaft 150 makes its rotation and preferably include bearing arrangement near its first and second end 151,152.As first end 151 of clutch shaft bearing device 180, between the antetheca 181 of an axle and an inaccessiable cylinder valve jacket 182 of air, provide to relatively rotate round axle 150.And second bearing 183 is installed near second end 152 of axle 150 on one side, makes between the rear wall 184 of axle 150 and clamshell 182 to relatively rotate.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 oil delivery, or because air flow causes other infringement.Clamshell 182 can be fixed on the workbench, or on other structures that fix on the ground.
Axle 150 is to act on axle by motor by belt and belt pulley upward to rotate.Belt pulley 192 is preferably formed an integral body with axle 150, and the output 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.
