Embodiment
Technical scheme is further elaborated with reference to embodiment and accompanying drawing.
Embodiment
A kind of spinning jet nozzle of sir jet spinning machines is present embodiments provided, including drafting system 25, the drafting system include
Drafting system roller 24, fibre bundle 2, the tow transport for example in the form of bifilar drafting machine sliver to the drawing-off corresponding to multiple
System roller 24.In principle, shown sir jet spinning machines also include the formation yarn unit 33 that is spaced apart with drafting system 25 and
The formation yarn members 8 of the hollow spindle form shown in Fig. 2, the formation yarn unit have what is shown in following accompanying drawing
Built-in spinning jet nozzle 3, wherein spinning jet nozzle 3 at least partially define minor air cell 6.In minor air cell 6, fibre bundle 2 or fiber
At least a portion fiber of beam 2 is provided with protection and twisted with the fingers.
Sir jet spinning machines can also include (the drawing of drawing unit 27 with preferably two pulling rolls 26 for rove 1
Unit 27 is not indispensable).It there is typically further the winding dress for being arranged in drawing unit 27 or forming the downstream of yarn unit 33
31 are put, the coiler device should include at least one pipe driver 30 again and be connected respectively with pipe driver 30 and in principle
Know the pipe keeper of (but being not shown), by the pipe keeper, pipe 29 can be fixed and be placed in rotation by pipe driver 30
During transhipment is dynamic, so as to by rove 1, be preferably wound up into by the support of traversing unit 28 on pipe 29.
Sir jet spinning machines is according to special air-jet spinning technique come work.In order to form rove 1, fibre bundle 2 is along conveying side
It is directed to T via the entrance opening 4 not shown in following accompanying drawing in the minor air cell 6 for the spinning jet nozzle 3 to form yarn unit.
Fibre bundle obtains protection and twisted with the fingers there, that is to say, that at least a portion fiber of fibre bundle 2 is by the spinning by suitably arranging
Air stream caused by air duct 9 is caught.Therefore, a part of fiber pulls out at least a small amount of distance and twined from fibre bundle 2
It is wound on the tip for the formation yarn members 8 being projected into minor air cell 6.
Finally, the fiber of fibre bundle 2 to be formed via the entrance opening 35 (participation Fig. 2) and being arranged in for forming yarn members 8
The drawing passage 34 of inside yarn members 8 and adjacent entrance opening 35 is drawn out from minor air cell 6.Here, it is last free
Fiber end also pulls along the direction of entrance opening 35 on helical trajectory and is wrapped in center traveling as winding fiber
Around core fibre, the rove 1 that there is desired protection to twist with the fingers is obtained.
Due to the twisting of the only part of fiber, rove 1 has a drawability, the drawability for downstream spinning machine,
Such as it is essential to be processed further in ring spinner for rove 1.On on the other hand, traditional air-jet spinning dress
Put and significant sth. made by twisting is applied to fibre bundle 2 so that necessary drawing-off can not be carried out again after yarn production.In this case,
This is also desired, because conventional sir jet spinning machines is designed to produce finished yarn, the finished yarn is generally intended to height
Intensity is characterized.
Fig. 2 shows the spinning jet nozzle 3 according to known, in the case of spinning jet nozzle 3 there is also formation yarn
