Abstract
The invention relates to a method for producing an air spun yarn (10). Two adjacent fibre bundles (4, 4') are drafted by virtue of a drafting device (5), and are then transmitted to a pneumatic twisting mechanism (6) and are drawn out from the twisting mechanism (6) in the form of yarn (10), and the yarn (10) is thereafter wound on a cross winding bobbin (11). According to the method, an air-flowing type true-twisting spinning mechanism having a drafting stop device is used as the twisting mechanism (6), and the two conveyed fibre bundles (4, 4') are differentiated from each other in at least one characteristic aspect, wherein the first fibre bundle (4, 4') is conveyed closer to a longitudinal axis of the twisting mechanism (6) than the second fibre bundle (4, 4').
Description
Technical field
The present invention relates to a kind of method manufacturing yarn, wherein two adjacent fibre bundles are drafted by drafting system, then be fed to pneumatic type twisting mechanism together and be drawn out of from this twisting mechanism with the form of yarn, after this this yarn is winding on cross winding bobbin.
Background technology
In open-end spinning, especially in the single spraying head spinning method being in leading position now, the fibre bundle left between the outlet roller of drafting system arrives the yarn inlet of the Yarn-spinning spindle of hollow via nozzle member.When fibre bundle enters in Yarn-spinning spindle, free fiber ends is wound around around the spindle top that the cone-shaped form of Yarn-spinning spindle is formed by circling gas flow and fiber is wound as so-called core part fiber in a spiral form when being gathered in described Yarn-spinning spindle by yarn.Core part fiber and so-called coiled fiber form new line jointly, and this new line is pulled out, monitored by yarn cleaning device, cleaned if desired and be wound.
When open-end spinning yarn, only by fiber roll around, the effect of tightening particularly by being wound up into the fiber on yarn core realizes yarn strength.For this reason, this fiber end must move in yarn core when the other end winding yarn core of fiber.The yarn core of the fiber other end can be tightened by means of only anchoring fibers end securely.
Many fibers of open-end spinning yarn are parallel with yarn core, only have the fiber of about 10% to 30% to be coiled fiber.Object will control spinning process like this, that is, make fiber can reel as far as possible equably and have enough coiled fiber all the time.
DE4032117A1 discloses a kind of spinning machine spinned for pneumatic false twisting, and position that this spinning machine spins is constructed to two-strand yarn position.After the fibre bundle of every two adjacent guiding to keep through drafting system and by guiding piece (such as infundibulate guiding device) in separated mode, fibre bundle separately arrives false-twisting device place after leaving drafting system.In order to prevent fibre bundle from forming ballooning of yarn and mutually disturb after leaving drafting system, between drafting system and a pair delivery roller of pneumatic type false-twisting device, arrange that so-called selecting device is using as guiding piece.This selecting device is driven with the speed higher than the speed of delivery roller and drawnwork device and in guide surface, is had bothrium for this reason.Thus achieve, the edge fibers stretched out in advance (that is, than fibre bundle core quickly) move in drawnwork device, wherein, these edge fibers are wound on the core of fibre bundle because of false twisting on this position.The edge fibers stretched out can not contact with each other with the fibre bundle rotated around himself axis because of false twisting, between the guide surface of this selecting device, be furnished with so-called separator in addition.
The shortcoming of this spinning machine is relatively many fibre sheddings, this is because fiber (its fiber end is not enough to be anchored in core) may be removed from fibre bundle axis, and therefore only access in the yarn joint produced deficiently or not and be used to anchor yarns.In addition, arrange that two false-twisting devices, sorting unit and separators are quite complicated and Expenses Cost, this is because need for each spinning position provides these devices.
Known a kind of pneumatic type spinning apparatus and a kind of spinning method in EP1279756A2.EP1279756A2 based on following aspect, that is, formed rotating fibers photosphere (Fasersonne) that carried by air-swirl, that be made up of fiber before entering spindle passage.Wherein, the end of fiber is arranged in the fiber photosphere of rotation and forms a part of yarn there in spindle passage.But owing to being not that all fibres is obtained by yarn forming process, therefore a part of fiber, particularly staple fibre falls into waste gas streams.
In order to improve yarn qualities and minimizing (short) fibre loss, the fiber comprised in waste gas in the first improvement project is crawled, regeneration and being reintroduced in spinning process in restriction position.Wherein, the position of this restriction can be positioned at the region of fiber optic ball center, particularly before drafting system or between drafting system roller.If be transmitted back to by fiber in fiber photosphere, then this produces via at least one independent fiber transmission channel.
Second improvement project is, is discharged in advance by fiber from fibre stream to be processed, therefore yarn forming process can be introduced the region of fiber optic ball center.
This spinning apparatus and being according to the shortcoming of the method for EP1279756A2, the so structurally very complicated and therefore also suitable Expenses Cost of the spinning apparatus of design.
A kind of yarn tight with artificial fibre bundle and manufacture method thereof is disclosed according to DE3433282A1.In order to produce such yarn (being used as the concept of line mistakenly here), to drafting system conveying fiber bundle, this fibre bundle is divided at least two fine fibre bundles in drafting process.Produce one by every bar fine fibre bundle and have coiled fiber and the yarn of corresponding rotation and two yarns will be merged into by rotation twists thread, wherein this is twisted thread and also has coiled fiber.
The shortcoming of the method is also, can cause many fiber losses.Because the deflection that some fibre end occurs from fibre bundle (stretching out the yarn core that reels) both realized because of the natural draft ventilation effect of drafting system roller, also by other External Force Acting, such as, realized by electrostatic field, suppressing action, scavenging action or mechanical arrangement.
As known at DE4032941A1, the uniform as far as possible yarn of one should be able to be spun out by a kind of method and a kind of device for pneumatic type false twisting spinning.Carry two fibre bundles for this reason or to drafting system, or carry by the fibre bundle separated before drawing-off or in drafting process to drafting system, wherein, at the end of drafting process, these two fibre bundles have the interval of restriction relative to each other.Fibre bundle reaches the interval of this restriction relative to each other by such mode, that is, wherein fibre bundle guides via infundibulate guiding device.In order to affect the coiling direction of edge fibers, between a pair delivery roller and false-twisting device, arrange so-called rotor, this rotor with than a pair delivery roller and drawnwork device faster speed drive and there is bothrium.These two fibre bundles are also advanced together on the outer surface of rotor, and the edge fibers stretched out from fibre bundle is sucked by two row's through holes of rotor and is carried in advance and exceedes fiber core junction surface.Fiber core junction surface is with less speed reverse slide on the outer surface of rotor.Article two, fibre bundle rotates around the axis of himself because applying false twisting thereon and enters together in the yarn inlet of false-twisting device, and the edge fibers of two fibre bundles is interconnected and is wound around fabric.
The shortcoming of the method is also the fiber loss of higher degree, especially compared with the fiber loss of staple fibre.Even fiber loss is accelerated to a certain extent, because the fiber of fiber end to reach in fibre bundle dark not, so it is separated therefore completely from this fibre bundle via rotor.
In addition, it is very complicated that a kind of like this false twisting spinning apparatus is structurally designed, because infundibulate guiding device must be guaranteed, fibre bundle to enter in drafting system with the interval of necessity and rotor makes edge fibers exceed fibre core junction surface.These mechanical parts must be present on each station.
In addition, although by the coiling direction affecting edge fibers according to the method and apparatus of DE4032941A1, can not affect the ratio of coiled fiber.
Summary of the invention
Therefore task of the present invention is, provides a kind of method, can produce the open-end spinning yarn of improvement by the method, and without the need to making open-end spinning frame become complicated and Expenses Cost.In addition by method according to the present invention, should be able to the ratio being responsible for the coiled fiber of yarn strength in yarn connection be had an impact.
This task will solve according to a first aspect of the invention.
In order to solve this task, be set to according to a first aspect of the invention, the air-flowing type with drawing-off stop device is really twisted with the fingers spinning mechanism and be used as twisting mechanism, and be transferred two fibre bundle is mutually distinguished at least one characteristic, wherein the first fibre bundle is carried than the longitudinal axis of the second fibre bundle closer to twisting mechanism.
If really twisted with the fingers in spinning process in air-flowing type, two fibre bundles are flowed to drafting system together and flow to twisting mechanism subsequently, then the position of every bar fibre bundle has a great impact open-end spinning process and the yarn texture tool that produces when yarn feeding.Finding in practice, when spinning open-end spinning yarn, more may be arranged in fiber core in middle position or closer to the fiber that middle position enters the fibre bundle in twisting mechanism.On the contrary, the fiber roughly departing from the fibre bundle of centre position feeding more may become coiled fiber and therefore more may be positioned on the outside of open-end spinning yarn.
Now according to the present invention, open-end spinning yarn can be spinned by two different fibre bundles and form.Wherein, by arranging this two fibre bundles when entering twisting mechanism, can the situation that after this fiber more still may be got back in yarn as coiled fiber as core part fiber be controlled.
The present invention proposes special circumstances simultaneously, and the fibre bundle of namely advancing near the longitudinal axis of twisting mechanism is positioned at the longitudinal axis place of this twisting mechanism.
The advantage that the present invention realizes especially is, different fibre bundles open-end spinning yarn can be processed into because of the method and produced yarn texture can be so affected, that is, the fiber of every bar fibre bundle more may use as fiber core or coiled fiber.
The advantage of the method is thus, when performing the method without the need to carrying out intricately transformation to open-end spinning frame and thus not producing too much extra cost.
According to a second aspect of the present invention, the advantageous feature that two fibre bundles are distinguished mutually is the average fiber length of fibre bundle.
Have longer average fiber length fibre bundle should when entering in twisting mechanism further from centre position and the comparatively staple fibre of the fibre bundle therefore protecting the longitudinal axis closer to twisting mechanism to aim at from airflow influence.
Occur because of the method in open-end spinning process thus and fiber loss less compared with method and apparatus well known in the prior art.
Thus in the method according to the invention, shorter fiber is also used in an economical manner, this is because by arranging that fiber and fibre bundle can have an impact the position residing in open-end spinning yarn to these fibers.
This especially plays a role when spinning 100% carded cotton (kardierterBaumwolle), because fiber loss produces special adverse influence to commercial value just in such infed material situation up to now.
In addition, can also affect now the ratio of coiled fiber because by arrange fibre bundle can have abundant coiled fiber all the time by guaranteeing and can realize uniform fiber roll around.
As described in third aspect present invention, another characteristic that two fibre bundles are distinguished mutually is the fiber raw material of fibre bundle.
Open-end spinning yarn can be manufactured in a controlled manner by this method by different materials.
Such as fibre bundle is made up of polyester fiber and another fibre bundle is made up of viscose.Can be furnished with by fibre bundle like this and affect which kind of fiber pointedly and be found as coiled fiber.
If the high wear-resistant of yarn and rub resistance important, then the fibre bundle with polyester fiber should be positioned at than having the fibre bundle of viscose more away from the position of twisting mechanism longitudinal axis.Thus in yarn core, the following characteristic of the fibre bundle entered in middle position more may play a role, i.e. the good hygroscopicity of viscose and soft sense of touch.Contrary in the outside of yarn, the characteristic (such as high-durability) of polyester is apparent.
Certainly within the scope of the invention other characteristic of two fibre bundles in other words another characteristic can be different.
According to a forth aspect of the invention, preferably drawing-off band is used as fibre bundle.
This modification has the following advantages, that is, drawing-off band can be directly out processed from drawing-off passage.By this mode, without the need to being manufactured the intermediate steps of flier rove (Flyerlunten) or so-called rove by drawing-off band.This has not only saved the time, also means and saves a large amount of costs, this is because not only eliminate the manufacture of flier rove like this, also without the need to manufacturing the machine of flier rove.
As described in fifth aspect present invention, in another embodiment, flier rove is used as fibre bundle.
This flier rove be also referred to as rove and during open-end spinning process need not again as drawing-off band by height drawing-off.The advantage of this modification is, can spin out very even and high-quality yarn.
According to a sixth aspect of the invention, every bar fibre bundle all has uniform fibers mixture.
In order to obtain the advantage achieved by the present invention, can use such fibre bundle, that is, wherein every bar fibre bundle all comprises uniform fibers mixture.That is, the fibre bundle with shorter or longer average fiber length is such as used.Therefore, although the fibre bundle used is distinguished mutually, every bar fibre bundle itself is consistent.In feeding open-end spinning process, depending on which kind of fibre bundle arrange in middle or in the mode departing from centre position, fiber is arranged in yarn core in advance or exists as the coiled fiber of yarn.
