Description
Technical field
The present invention relates to a kind of methods of sir jet spinning machines of the operation at least one spinning jet nozzle, wherein the spinning
Nozzle includes the vortex chamber of inside, wherein being inputted fibre bundle by the entrance of the spinning jet nozzle during spinning jet nozzle works
The spinning jet nozzle, wherein the spinning jet nozzle has the air nozzle that one or more are connected to the vortex chamber, spin air
The vortex chamber is flowed by the air nozzle during the spinning jet nozzle works, it is empty to be generated in the vortex chamber
Gas eddy stream, wherein the fibre bundle obtains certain twist in the vortex chamber by the air-swirl, thus from described
Yarn is formed in fibre bundle, the yarn leaves the spinning jet nozzle finally by outlet.
The present invention also proposes a kind of sir jet spinning machines at least one spinning jet nozzle, the sir jet spinning machines be used for from
Input in the fibre bundle of the spinning jet nozzle and manufacture yarn, wherein the spinning jet nozzle have for the fibre bundle entrance,
Internal vortex chamber, the resultant yarn element for stretching into the vortex chamber, and yarn for being generated in the vortex chamber outlet,
The wherein described spinning jet nozzle has one or more air nozzles being connected to the vortex chamber, and spinning air is in the spinning jet nozzle
It can be admitted to the vortex chamber by the air nozzle during work, to generate air-swirl in the vortex chamber.
Background technology
Sir jet spinning machines with corresponding yarning position is known in the prior art, is used for from elongated fibre bundle
Middle manufacture yarn.In the process, the outer fiber of fibre bundle by air nozzle the generated air-swirl in vortex chamber,
And wound around internal core fibre in the entrance area of resultant yarn element, it eventually forms and decision is risen to desired yarn strength
Property effect winding fiber.It can thus generate with the yarn really twisted, it finally can be by extraction channel by from vortex chamber
It draws and for example coils on some sleeve.
Also that is, the concept " yarn " in the present invention is generally referred to as certain fibre bundle, wherein at least a part of fiber surrounds
Inner core is wound.Therefore, the traditional yarn that certain material can be for example processed to by loom, equally
It is included.The invention also relates to manufacture so-called " rove " (also referred to as：Lunte sir jet spinning machines).The spy of this yarn
Sign is, with being enough yarn transporting to some strength of next weaving loom, still has deformability.Also
I.e., it is possible to by the weaving loom (such as ring spinner) of deformation device (such as drafting system), processing rove rove is deformed,
Then finally spinned to rove again.
It, can be in resultant yarn member when processing chemical fibre (such as polyester) or the mixture being made of natural fiber and chemical fibre
Deposit is generated on the surface of part.Its reason is：The manufacturing process of chemical fibre includes so-called preparation in the fabrication process
Continuous fiber.In the process, apply the preparation agent (being usually oil) with different additive toward continuous fiber, so as in high speed
Under continuous fiber is handled, such as drawing-off.These prepare agent and can be partly attached on chemical fibre in next processing procedure,
And impurity is generated in sir jet spinning machines.
Deposit is mainly formed on the surface being in contact with the fiber of fibre bundle or yarn, such as stretch into vortex chamber at
On the surface of yarn element.Deposit may also produce on the surface of vortex chamber or the fiber guide element for forming spinning jet nozzle entrance
It is raw.These attachments can weaken the surface quality of respective surfaces, so that the air-flow in spinning jet nozzle is deteriorated, to reduce
The quality of manufactured yarn.Therefore, it is necessary to respective surfaces periodically be cleaned, so that the quality for spinning yarn remains unchanged.
For corresponding deposition is minimized the horizontal or contaminated surface of cleaning, it is known that scheme is to add additive
To spinning air.Such as this scheme was described in JP-2008-095-208.
Invention content
The object of the present invention is to propose a kind of solution for being used for preventing or at least inhibit to be formed deposit in spinning jet nozzle
Scheme.
The present invention to reach above-mentioned purpose solution be the feature with independent claims a kind of Air-Jet Spinning
Yarn machine and a kind of method.
Core of the invention theory is, the indoor temperature that is vortexed is greatly reduced compared with prior art.Such as it can lead to
Following manner is crossed to realize this point：The spinning air is cooled before entering the vortex chamber and by through in the form of cooling
