Description
Technical field
The present invention relates to a kind of method of producing a kind of short fibre yarn.
Background technology
As everybody knows, produce short fibre yarn different production methods is arranged.
Except ring spinning and rotor spinning, for example centrifugal spinning is exactly early known a kind of method.
Pot spinning method is divided into two kinds of different spinning forms again, i.e. one-step method and two-step method spinning.
These two kinds of spinning forms, infed material can be the ribbon that leaves in the yarning can, an or rove of rove bobbin, in a drafting system, carry out drawing-off, and be contained in the yarn-guide tube that can move axially supporting by one and carry yarn to enter in the spinning tophan box of high speed rotary according to desired yarn count.
By the infed material that yarn-guide tube exports out, form that a spun yarn is around on the centrifugal tank skin and by through taking away together.
Fibrous material is by the rotation of tophan box and obtain the twist.
The yarn that forms by twisting is to be around on the centrifugal tank skin and the so-called yarn cake of formation in jar by the yarn-guide tube that can move axially supporting.
One process spinning, the feed speed of its tophan box revolution and infed material is so mutual harmony, the yarn of the resultant yarn cake of having reeled has its enough twist and can be unwound in next step operation on the rewinding pipe that enters in the tophan box.Afterwards, this cop that in the unwinding process, forms will one with bobbin winder that production procedure is connected on be wound up on the cross winding bobbin of a large volume.
Aspect the two-step method spinning, the supply rate of tophan box revolution and infed material is such selection, promptly is coiled in the yarn of tophan box inwall in the first step spinning stage, only has earlier the part of its final twist.The yarn that the part twist is arranged of coiling resultant yarn cake has only it in second spinning stage in step during from the tophan box unwinding and directly be wound up into an intersected coiled bobbin period of the day from 11 p.m. to 1 a.m just obtain the twist that it lacks on a winding device.
No matter be one-step method or two-step method centrifugal spinning, the yarn amount of this discontinuous production is subjected to the restriction of yarn cake volume, therefore by forcibly producing the intersected coiled bobbin period of the day from 11 p.m. to 1 a.m, must carry out interconnecting of many loose threads.
From a kind of centrifugal spinning machine/bobbin winder that DE 40 00 059 A1 learn, its work ingot position is respectively the winding device under a centrifugal spinning jar and.
Known said apparatus is by two above-mentioned step spinning method work.Be that spun yarn is in the at first part twisting of first step spinning stage.When the first step spinning stage finished, infed material disconnected in the drafting system zone.The loose thread that part twist yarn is arranged that link to each other with the yarn cake this moment is drawn in the intermediate storage by an injector.And then, the loose thread same loose thread that obtains to twist fully from cross winding bobbin in a device of splicer that is stored in the intermediate storage is connected.
By the corresponding transmission of cross winding bobbin, promptly began for the second spinning stage in step.
In the second spinning stage in step, be wound in the tophan box yarn cake to go out from the tophan box unwinding, and obtain its final twist with sliver partial draft, be wound up on the cross winding bobbin.
That yes is imperfect for this known spinning method, the yarn joint of in splicer, finishing, and especially from the knot structure, the yarn that obviously is spun into " regular " is distinguished to some extent all the time.
It is impossible promptly coming the yarn of production same yarn to connect with this device known to everybody.
Summary of the invention
From above-mentioned prior art, task of the present invention is, aspect two-step method centrifugal spinning, develops a kind of improvement yarn quality, especially in the sand quality in link position zone.
According to the present invention, this task can solve by the described a kind of method of claim 1.
The favourable technical scheme of this method all belongs to the dependent claims content.
The method according to this invention has special advantage, and promptly the knot structure of two loose thread tie points much at one.
That is, new yarn is seen the similar same yarn of fiber alignment/drawing of fiber/twist in its link position zone by its cross section.
Because the tie point by producing approximate same yarn no longer includes " yarn length that nothing is spliced " QUALITY STANDARD, adopts the present invention in addition, can significantly reduce the volume of tophan box, thereby reach obvious saving transmission energy.
According to method of the present invention, except improving the finished product yarn quality, also improved the economy of centrifugal spinning machine.
In embodiment preferred, the loose thread under the cross winding bobbin unwinding as described in the claim 2,, is handled in a pretreatment unit known to everybody earlier before the infed material at lay.
Promptly the loose thread of twisted yarn fully for example is subjected to gas shock in a preliminary treatment tubule.
A kind of preferably form of implementation is, described in claim 3, for example loose thread has the partly untwisting of yarn length of a regulation at least by corresponding air blowing.
The possibility of another kind of preliminary treatment loose thread is, yarn attenuated described in claim 4.
Loose thread attenuates and also can carry out in a special-purpose preliminary treatment tubule, for example is mounted with the tubule of comb shape element, and loose thread is stretched by the shredding of comb shape element or along comb.
Another possibility be guarantee that the loose thread of yarn spun in the lay infed material beginning under the unwinding from the cross winding bobbin before, have the twist that is less than regular yarn, so yarn is with higher transporting velocity (claim 5) doff during the stage in the second step spinning.
Owing to improved doff speed, yarn particularly obtains the corresponding few loose thread of the twist, spins operation for the later beginning and plays positive role at the link position of loose thread.
As described in claim 6 and 7, loose thread is that later foundation yarn joint of the present invention process has been done this preparation, promptly not only at the initial spinning process in first step spinning stage, and when finishing, all improves the draft speed of drafting system in short time in the first spinning stage.For this reason, for example the front roller of drafting system to can be in a short time with higher speed transmission.These measures are got ready loose thread, guarantee that the yarn link position has the structure of approximate same yarn.
In addition, a kind of preferred form of implementation is, in the rotating centrifugal jar, be wound into the part twisted yarn of yarn cake for unwinding, can be by described in the claim 8, change the right outbound course of drafting system front roller, also can be described by claim 9, adopt a pressure roller of pressing a rotating doff roller of yarn unreeling direction and a rotatable supporting.
These two kinds of forms of implementation guarantee that the part twisted yarn of coiling resultant yarn cakes can be in the unwinding of the second step spinning stage safety, and yarn also obtains the not enough twist when unwinding.
This yarn is being wound up on the winding device on the cross winding bobbin as previously described simultaneously.
