Definitions
- the invention relates to a method for producing mixed yarns according to the preamble of the independent claim.
- Blended yarns are now carried out in three different, independent sub-processes and in different operations.
- Each sub-process as such is set up for optimal speed. Of course, this affects not only the sub-process as such, but also the entire periphery around the sub-process.
- the process sequence begins with the spinning of synthetic fibers. This spinning stretching takes place at a first, very high processing speed and is carried out on large plants in a spinning mill. Everything is geared towards large production. Each spinning machine has a large number of individual spinning positions. Therefore, the raw yarn produced is also wound on large spinning reels of normally 30 kg yarn weight.
- the texturer resp. The stretch-texturing process takes place in a separate plant, usually in a separate factory.
- synthetic fiber raw yarn is removed from the supplied 30 kg spools and textured in a known manner. Since the volume increases, texturing can only take place at a significantly slower second speed. To ensure that texturing is fast and productive enough, each texturing machine has a large number of texturing points.
- the textured yarn is then usually wound onto packages with a yarn weight of 5 kg. This process takes place in our own production facilities. The 5 kg yarn packages are then passed on.
- the textured yarn is unwound from the 5 kg. Wraps and proportioned with elastane, lycra and similar fibers in an air swirling process. This process is always dependent on the quality of the textured yarn and the type of admixture, for example intermingling and the quantitative proportion of the fed fibers dependent.
- This third sub-process will be carried out at a third, usually even lower, speed. So that this sub-process is productive enough, each admixing, for example, swirling machine has a plurality of admixing, for example swirling points. Again, this takes place in a separate and specially designed production facility.
- the object of the invention is to change at least one of these three sub-processes so that at least two of the sub-processes can be combined.
- An additional advantage of the invention is that at least one rewinding point from one reel to the next and thus also a source of error is eliminated.
- Another advantage of the invention is that two previously separate production facilities can be combined. Either texturing takes place in the spinning mill directly after the spinning process or the texturing process runs directly before and together with the Airtex process. As a result, there is no longer any need to transport yarn packages between two production sites.
- FIG. 1 process sequence from spinning to the finished elastic yarn according to the prior art
- FIG. 2 process flow according to variant 1 by combining two sub-processes
- FIG. 3 process sequence according to variant 2 by combining two other sub-processes
- FIG. 1 The process flow according to the prior art is shown in FIG. 1.
- the production of a blended yarn begins with the spinning of a synthetic fiber raw yarn in the first sub-process P1.
- This raw yarn is produced in large quantities using known technology in known spinning machines.
- the raw yarn is spun from a granulate and stretched appropriately. Both are done on the same machine and mostly in the same operation.
- Such spinning machines work with a very high production speed V1.
- Each spinning machine has a large number of individual spinning positions. Since the production speed V1 is high, the take-off of the raw yarn for further use must also be appropriately equipped.
- the raw yarn produced is therefore also wound onto large spinning reels W1, normally weighing 30 kg each.
- the spinning reels W1 are now transported to a texturing company T1.
- the raw yarn is drawn off from the spinning reels W1 and is now treated in tetexturing machines as a second sub-process P2.
- the raw yarn gets a desired texture.
- the volume of the yarn increases considerably.
- each texturing machine has a large number of texturing points.
- the texturing machines work with a second production speed V2 suitable for these machines.
- the textured yarn is then usually wound onto second windings W2, each with a weight of 5 kg.
- the second reels W2 are now transported to the next company T2
- the textured yarn is unwound from the 5 kg windings and proportionally provided with elastic fibers in an air swirling process.
- This third sub-process will be carried out at a third, usually even lower production speed V3. So that this sub-process is productive enough, each admixing, for example, swirling machine has a plurality of admixing points. In this case, an additional filament is drawn off from a fourth winding W3 and swirled together with the textured yarn at the mixing point to form the mixed yarn. It is obvious that this can be done using various methods known per se, such as air swirling, twisting, twisting and the like.
- the finished elastic yarn is now placed on third packages of around 6 kg each Thread weight wound up.
- the second windings W2 and the third windings W3 can be the same, since the volume of the finished elastic yarn differs only slightly from the textured yarn only, although the yarn weight increases by the proportion of the elastic fibers.
- the second subprocess P2 and the third subprocess P3 are now combined. This is done by adapting the second production speed V2 to the third production speed V3 to such an extent that both are identical. This makes it possible for a swirling point W1 to be connected directly to each texturing point T1 and for the finished elastic yarn to be wound up again. This means that the second transport T2 of the second reel W2 from the second sub-process P2 to the third sub-process P3 including unclamping, chucking and mounting on the elements of the following processing stage is omitted. It is obvious that production is cheaper and there are no sources of error. It is also possible to dispense with an intermediate quality control after texturing. The configuration of the elements required for the second subprocess P2 is discussed in more detail in connection with FIG. 4.
- the first subprocess P1 and the second subprocess P2 are now combined. This is done by adapting the second production speed V2 to the first production speed V1 to such an extent that both are identical. This makes it possible for a single texturing point T1 to be connected directly to each individual spinning position S 1. The finished textured yarn is then wound up again. This means that the first transport T1 of the heavy spinning reels W1 from the first subprocess P1 to the second subprocess P2 including unclamping, clamping and winding onto the elements of the following processing stage is omitted. Here too, steps such as intermediate quality control can be omitted.
- the configuration of the elements required for the second subprocess P2 is discussed in more detail in connection with FIG. 4.
- the second production speed V2 of the second sub-process P2 can be adapted to the first production speed V1 of the first sub-process P1, the second sub-process must be changed accordingly and equipped with the necessary means.
- FIG. 4 The adaptation of the second production speed V2 is made possible in that a texturing machine is constructed from individually controllable texturing modules 4. This means that each texturing module 4 has its own control. In addition, it must be of compact construction, since it is to be arranged directly in front of the swirling point of the third sub-process P3 or directly behind the spinning point of the first sub-process P1. So that a texturing module 4 can be built sufficiently compact, it is equipped with a heating section with its own special preheating 41, 42.
- the raw yarn which comes directly from a spinning position of a spinning machine or from a spinning reel W1, reaches a first heating device 41 via a yarn inlet 48, where it is heated to a first preheating temperature T1.
- the preheated raw yarn is then pre-drawn to a certain extent, whereupon it is heated to the full texturing temperature T2 using a second heating device 42.
- the fully warmed raw yarn now runs over a twist stop 43, through an actively cooled texturing section 44 to a false twist element 45.
- the twist generated by the false twist element 45 runs backwards to the twist stop 43.
- the texture is generated in the yarn.
- the texture is frozen or fixed during production, in that it is cooled to a fixing temperature T3.
- the now textured yarn then arrives at an elasticity correction station 46, where it is brought to a selectable temperature T4.
- T4 a selectable temperature
- the second production speed V2 can be adapted sufficiently to the other subprocess P1, P3.
- the drive, such as preheating, texturing heating and active cooling in the cooling channel of the texturing section 44 can be controlled individually for each texturing module 4.
- the pre-stretching can either be produced with two heating godets arranged one behind the other, which have different speeds and possibly different temperatures. But it can also be achieved with a stylus and a heating godet.
- the preheating and the heating must be provided with sufficient power. This can be done, for example, by using heating godets, infrared, air nozzle heating, resistance contact heating and combinations thereof.
- the cooling must be able to provide sufficient power and be able to transfer it to the yarn, whereby special attention must be paid to the fact that yarn must be cooled to the necessary temperatures during the full production speed during texturing. Not only is air cooling suitable for this, but also liquid cooling with and without direct contact with the yarn.
- the heat in the heated yarn can also be dissipated quickly enough from the cooling section.
- a cooling channel can be filled or rinsed with water, oil, refrigerant or liquid sodium or saline medium, a salt or salt mixture with a suitable melting temperature.
- a coolant which evaporates in the temperature range between about 50 ° and 300 ° is particularly suitable.
- the latent heat or the resulting evaporation cold helps considerably to remove enough heat from the yarn to cool it down to the appropriate temperature within the texturing section 44.
- Thread tension control with measurement and control can be just as important.
- a sensor for monitoring the thread tension is arranged in the area of the texturing section 44 and its measured values are used to regulate the thread tension.
- the thread temperature be measured as contactlessly as possible, at least in the area of the false wire organ 45. From these measured values, heating and cooling are regulated as simultaneously as possible by online evaluation. This is essential so that the adjusted second production speed V2 can be maintained. The more precise the temperature control, the better the adaptation to the previous or subsequent sub-process.
- FIG. 5 shows schematically a combination of the second subprocess P2 with the third subprocess P3 in connection with a single stretch texturing module 4.
- the additional filament is now mixed in from the fourth winding W4 after the directly after the withdrawal from the texturing section, as the elasticity correction station 64 in the third sub-process P3. In other cases, this can be done by swirling, twisting or twisting. Because of the individual adaptability of the speed of the individual texturing module, the production speeds V2 and V3 of the two sub-processes P2, P3 can be precisely coordinated and optimized.
- Such a mixed yarn can be produced by admixing a synthetic filament, for example one with special elastic properties or else a filament made of cotton, wool and others.
- the combination of the second and third subprocesses P2, P3 according to the invention can be expanded by a further subprocess without coils in between. It is thus possible to feed the mixed yarn produced directly to a circular knitting machine, which these individual process speeds can be adapted to one another under the conditions mentioned and with the means mentioned.
