Definitions
- the present invention relates to a method and a plant for processing fibers, and more particularly to a process for producing a yarn by the air-spinning process.
- the fibers of a sliver are spirally swirled by means of compressed air in a nozzle and processed into a yarn.
- a fiber length of at least 30 mm is necessary in order to achieve sufficient yarn strength.
- Mainly synthetic fibers such as viscose or polyester, or yarn blends of cotton with viscose or polyester are processed.
- the fibers are carded in accordance with the prior art and doubled in three subsequent drafting systems, each with six to eight cans template and stretched. It is in the preparation of the sliver to be processed to a very complex process, since the space required for the card and the subsequent three drafting is very large. Furthermore, the cost of can transport, each with different fiber quality is very large and labor-intensive.
- the object of the invention is to provide a simplified method and the associated system for processing fibers.
- a carded fiber band formed on a carding machine is preferably pre-stretched more than three times on this card and deposited in a first can.
- At least nine of these pre-stretched slivers produced from a plurality of the first cans, corresponding to the number of slivers provided by / stretched, are laid without distortion, preferably stretched at least 8.5 times into a stretched sliver and deposited in one of second cans , This thus produced, stretched sliver in each of the second cans is presented to a spinning station of an air-spinning machine. There, the presented, stretched sliver spun accordingly. Alternatively or additionally, the stretched sliver presented to the air-spinning machine is preferably stretched at least 20 times in relation to the carded sliver.
- the core idea of the invention is a stretching of a preferably heavy, carded sliver in only two steps.
- a first step the carded sliver is pre-stretched on the card in an integrated section and placed in one of the first cans.
- first can in the context of the invention means: for the picking up of the sliver produced on the carding machine
- second can means accordingly: intended for picking up the stretched sliver produced on the line; then the air-jet spinning machine is submitted.
- the first and second cans can be completely identical and, in the context of the method, differ from one another only with regard to the type of fiber sliver picked up.
- a second step at least nine of these extended slivers of a stretch are presented.
- a driven gate is used to run the slivers without distortion in the track.
- the second stretching of the sliver allows, in turn, removal of the hook located at the rear ends of the fibers in the direction of transport.
- the fibers are withdrawn from the respective first jer in reverse direction to the card so that the direction of movement of the fibers in the course reverses. This makes it possible to eliminate as much as possible the hooks at both ends of the fibers due to the two-time stretching.
- a heavier strip is preferably warped or stretched by at least 8 times, 8.5 times or even 9 times in the path (30), can be dispensed with two separate draw frames.
- the carded sliver has at least 2.7 ktex. Due to the high band weight can be worked with greater delays.
- the carded sliver is stretched on the card by at least 2.5 times, 3 times or even at least 3.5 times. This results in the best yarn values on the air-spinning machine for the entire process.
- the card Due to the preferably unregulated stretching of the sliver on the carding results in a very space-saving arrangement of an integrated route that can be placed in vertical alignment on the head of a can tray.
- the card will produce at least 80 kg / h sliver. This results in an optimal machine configuration to provide the spinning units of the air spinning machine with a minimum of cards and tracks
- the carded sliver has at least 2.9 ktex, preferably at least 3.5 ktex.
- the sliver when changing the can, can be stored on the card prior to the pre-stretching.
- the card does not need to be stopped when changing the can, but can continue with a lower productivity, whereby the productivity of the card is lowered so that no loss of quality occur in the produced, carded sliver.
- the card in the storage mode (ie during the can change), the card is operated at a speed of at least 100 m / min.
- a stretched sliver is produced with a single regulated stretch, which has a sufficient quality for presentation to an air spinning machine.
- at least 12 slivers run into the line without distortion.
- a plant according to the invention for producing a yarn by the air-spinning method comprises a carding machine with an integrated path and a can changer, a single drafting system, which is designed as a regulated drafting system and to which a driven gate is arranged, and an air-spinning machine.
- the system can be operated with a greater variation in band numbers and higher Verschn, which can be dispensed with two drafting.
- the system becomes more compact and the can change can be reduced to a minimum.
- the carding machine advantageously has a transverse belt withdrawal with which the carded nonwoven fabric is drawn off as a card sliver or sliver.
- a belt loop memory is arranged between the card and the integrated route, with which a continuous operation of the system is ensured. The fact that the card to change the can not be stopped, higher productivity can be achieved with a constant quality.
- the driven gate on a drive which is operable and controllable independently of a drive of the drafting system.
- the tensioning distortion can be regulated very precisely on the slivers when entering the drafting system
- the drafting system on a track regulation, which adapts the main delay of the route to possible mass fluctuations of the incoming slivers.
- the very high doubling of at least nine slivers, preferably 12 slivers, and the high distortion in the track results in a high quality sliver, which can be presented without further processing of a spinning station on an air-jet spinning machine.
- the distance regulation is preceded by a funnel, which has a decreasing opening angle in the strip running direction. In the funnel thus takes place a first compaction or compaction of the at least nine slivers, wherein the decreasing opening angle ensures continuous compression.
- the opening angle can decrease in steps or continuously.
- the stepped arrangement of the opening angle can be implemented inexpensively in terms of production technology.
- the continuous decrease in the opening angle is more advantageous for the first densification of the slivers.
- Each of the aforementioned systems is preferably arranged to be operated according to one of the aforementioned methods. Ie. a system that is relatively simple in construction is capable of achieving the advantages indicated in the aforementioned methods.
- FIG. 1 shows a plant layout according to the prior art
- FIG. 2 shows a plant layout according to the invention
- Figure 5 representation of a sliver inlet with measuring rollers on the track.
- Figure 1 fibers are aligned in a carding machine 10 and stored as a carded sliver in a pot C. A total of six to eight of these cans C are submitted to a first distance DF1 and relined and stretched. The sliver produced in the first distance DF1 is again deposited in a can C1 and doubled and drawn with another five to seven slivers in a second distance DF2. The then stretched sliver is deposited in a can C2 and stretched with a total of six to eight slivers in the distance DF3. The sliver stretched in the third section DF3 is in turn deposited in cans C3 and presented to the air-spinning machine 50.
- the third route DF3 is designed as a regulating section.
- the sliver is warped six to eight times in each span DF1, DF2, DF3 to give a maximum total stretch of up to 512x.
- the main disadvantages of this method are the high space requirements for a total of five machines with the associated cans and the laborious and labor-intensive handling of the cans, with which the sliver is transported to the next machine.
- the inventive method according to Figures 2 to 5 provides a stretching of the side of the card 10 carded sliver in only two Steps ahead. The first (pre-) stretching takes place on the carding machine 10 before the sliver is deposited in the can C.
- an integrated section 20 with an unregulated delay zone is arranged in front of and above the can tray 22, which stretches the card or sliver by a factor of> 2.5, preferably 3.0 and more preferably> 3.5.
- the then laid down in the pot C, by / extended sliver is transported to a distance 30 and there stretched by a factor of> 8.5, preferably by a factor> 9, stored in a pot C1 and processed in the air spinning machine 50 into a yarn ,
- the invention has the advantage that it is possible to dispense with two full-length drafting systems, for example DF1 and DF2, and thus only two instead of four can transports for the sliver are necessary.
- the sliver is stretched only twice, with a distance 20 on or in the can shelf of the card 10 is integrated.
- Figure 2a shows a suitable plant.
- the functionally integrated into the card 10 route 20 has a much smaller additional space compared to the card 10 with Kannenablage than two full paths DF2, DF3 with respective gates and cans.
- FIG. 2b shows the card 10 with integrated section 20 in greater detail and serves to clarify the size relationships of this part of the system. It can be seen in particular that the integrated route 20 has dimensions that in extreme cases, no enlargement of the can shelf in length and width result, so that the space required by card 10 and can tray 22 does not change and so in existing systems, for example as a substitute wholly or partially integrate.
- FIG. 2c shows a section 30 with, by way of example, twelve canned cans C, which include / extend slivers which enter the route 30.
- FIG. 2d shows the air-spinning machine 50 from one end side, ie in the direction of its longitudinal extension.
- the technological difference with the prior art is that, according to the invention, a much heavier and thicker strip is processed throughout the entire process, which is much more stretched in the single section 30.
- the sliver produced in the carding machine 10 has a quality of advantageously at least 2.7 ktex, preferably at least 2.9 ktex. Particularly good results can be achieved with a carded sliver of at least 3.5 ktex.
- the card 10 has a transverse band deduction due to the weight of the band, with which the carded nonwoven can be pulled off to a carded or card sliver.
- the production of card 10 is at least 80 kg / h.
- a belt loop memory 25 may also be useful, which will be explained in detail in Figure 3.
- the integrated into the tape tray 22 section 20 has been modified to heavy and thick slivers by only one unregulated delay zone is used, in which the incoming slivers are stretched by a factor of> 3.0, preferably> 3.5.
- the arranged between the card 10 and the integrated track 20 memory is preferably designed as a ribbon loop memory 25, with which the continuous process of sliver production is to be ensured. Without the tape loop memory 25, the card 10 would have to shut down the production output much more when changing the can, which is Quality degradation in the uniformity of the sliver 15 and reflected in an increase of the thin spots in the produced yarn.
- the mass fluctuations in the fiber sliver 15 produced by different production capacities have an extremely unfavorable effect on the yarn produced in the air spinning machine in the subsequent very strong two-stage drawing on the section 30 or in its drafting system, which is thereby uneven. After the SdT, unevenly made card sliver can be improved in quality by multi-stage drawing, whereby the slit store 25 is not needed in this application.
- the carded sliver 15 which is formed by the transverse band deduction within the housing 1 1 of a nonwoven, withdrawn through an opening 12 of the card 10 and passed through a ring 13.
- the sliver 15 is then fed via a drive roller 27 via a roller 26 to a roller 21, which then directs the sliver 15 in the integrated path 20.
- the rollers 21, 26 and 27 are arranged at a height above the integrated track 20, which may be about 1, 8 m to 2.5 m.
- the rollers 26 and 27 may be arranged on a separate frame which is fixed on the floor or on the ceiling of the spinning mill.
- the drive roller 27 may be driven, idle, or fixed so that the sliver 15 is pulled from the integrated track 20 or the head and slides over it.
- the drive roller 27 can be operated at a speed which corresponds to an entry speed of the can changer 22 or the distance 20 at which the sliver 15 is drawn into the can changer 22.
- the delivery speed of the sliver 15 from the card 10 can be between 140 to 250 m / min, preferably 200 m / min, amount.
- the carded sliver 15 can be accelerated to a speed of about 700 m / min before it is deposited in the can C. If the pot C is filled, the sliver 15 must be significantly reduced in speed or stopped until the filled can C is replaced by a new, empty pot C. For this process, a certain amount of time is required in which the card 10 is actually not intended to supply any sliver 15. Only this leads to a very unsteady operation of the card 10, in particular due to the frequent deceleration to a standstill and Wiederbe devisens the relatively large carding drum. To avoid this, an intermediate storage of the sliver 15 between the rollers 26 and 27 and between the roller 27 and the ring 13 is provided.
- the drive roller 27 is driven and at the same time the sliver between the drive roller 27 and a pressure element 28 (pressure roller or spring) clamped.
- the sliver 15 is thus transported independently of the speed of the card 10 and the integrated drafting system 20 by the drive roller 27 on.
- the card 10 is braked to a speed at which a minimum of mass fluctuations in the sliver 15 produced.
- the delivery speed of the carding machine 10 is preferably at least 100 m / min.
- the drive roller 27 is operated at a speed which is equal to or less than the output speed of the card 10 on the ring 13. This results in a loop in the sliver 15 between the ring 13 and the drive roller 27, which may extend to the ground. Since the fiber can 15 is not further transported by the can change on the drafting system of the integrated section 20, a second loop between the rollers 26 and 27. This loop formation, which results from the difference in the transport speed between drive roller 27 and card 10, is sufficient as a temporary storage for the time of a can change, in which the card 10 produces at a reduced speed.
- the route 30 differs from the prior art by the processing of at least 9 of / extended slivers (see Figure 2a), preferably 12 of / extended slivers (see Figure 2c), by the factor> 8.5, preferably in order stretched the factor> 9 and stored in the cans C1 as a stretched sliver.
- a delay up to a factor of 12 may be useful. Since the inlet of the route 30 provides a much longer gate 40, enter through the 9, 10, 12 or more slivers in the drafting head, can be compensated with a driven gate 40 due to the longer transport path, the resulting friction and regulate the tension distortion.
- the gate 40 has a profile 41 which extends in the working direction of the route 30 and is arranged above the cans C.
- the profile 41 is mounted on at least one support 42, which is preferably adjustable in height.
- rotatable deflecting elements 43 Arranged laterally on the profile 41 are rotatable deflecting elements 43, wherein each can C is associated with a rotatable deflecting element 43.
- the deflecting elements 43 extend horizontally and at right angles to the longitudinal axis of the profile 41 and lead the sliver from the cans C in the drafting 30. They are driven by a drive element, not shown, which is disposed within the profile 41.
- a drive 44 for example a controllable electric motor or a servomotor, is arranged on the profile 41 at an end opposite the distance 30. Via a belt drive or another drive element which can be integrated in the profile 41, the deflecting elements 43 are driven. This is done to reduce the tensile forces on these slivers due to the extended inlet path of the slivers in the route 30 and the associated friction.
- the tensioning distortion of the slivers can be optimally adjusted to the distance 30. Due to the long feed path of the slivers from the last can C to the drafting system results in a non-driven gate high friction, which may be different for each sliver. By the driven deflecting elements 43, this friction can be minimized and at the same time the Anspannverzug the slivers are adjusted to the drafting out.
- the section 30 is a regulating section with a pre- and a subsequent main draft zone.
- a pair of contact rollers 35, 36 is arranged for the distance regulation 34 in front of the section 30, with which variations in thickness in the sliver are measured and compensated in the section 30.
- the contact roller pair 35, 36 is further preceded by a tape guide as a hopper 33, which is adapted to receive at least 9 slivers and lead into the Tastwalzenzip 35, 36.
- a first feeler roller 35 is fixedly arranged on or on the track 30.
- a second feeler roll 36 is movably arranged to the first feeler roll 35, wherein the second feeler roll 36 is movably mounted on a lever 37 with a pivot point.
- the sliver is guided and measured the mass fluctuations.
- the lever 37 is acted upon by a pressure element 39, which may be formed as a spring or piston.
- a pressure element 39 which may be formed as a spring or piston.
- the feeler roller 36 springs back over the lever 37, whereby a signal is produced in the sensor 38, which is processed in the control of the path 30 and adapts the delay of the path 30 in the main delay.
- the distance regulation 34 is preceded by a funnel 33, which has a variable inlet angle ⁇ in the strip running direction 32.
- the funnel 33 is formed in two stages, wherein the first stage has an opening angle a1 between 1 10 ° and 80 ° .
- the opening angle a2 of the second stage is between 80 ° and 45 ° .
- the opening angle of the funnel can also be rounded and thus taper without step or step continuously from 1 10 ° to 80 ° to 80 ° to 45 ° .
- Each spinning station in the air-jet spinning machine 50 is provided with a sliver C1 with sliver from the line 30, which processes the sliver at a speed of 500 m / min with a default factor of 216. At this speed, a yarn can be made with Ne30. With a yarn of Ne40, the production speed of the air-spinning machine is around 420 to 470 m / min. Due to the fact that the card has an integrated section 20, the section 30 operates with higher deflections and the section 30 simultaneously stretches more than eight slivers, the entire process can be optimized and two separate drafting arrangements can be dispensed with.
- a viscose sliver with a fineness of 9.45 ktex is processed at a production rate of 80 kg / h.
- the result is a card sliver that comes out of the integrated section 20 with a quality of 3.05 ktex.
- the card sliver is warped by a factor of 3.1 at a speed of 437 m / min and deposited in a pot C.
- a total of 12 cans C are presented with this sliver of the route 30. That is, 12 slivers are doubled and drawn together at a speed of 500 m / min. The stretching takes place with a factor of 8.61, so that a fiber sliver with a quality of 4.25 ktex is produced at a production rate of 127.5 kg / h.
- the resulting sliver is placed in a pot C1, and fed to an air-spinning machine.
- the air-spinning machine processes the sliver at a speed of 500 m / min and warps the sliver by a factor of 216, creating a Viscose yarn with Ne30. Since only one pot C1 is submitted to each spinning station, the production capacity of this spinning station is 0.6 kg / h at 100% efficiency.
