Description

Yarn processing method and yarn processing machine

Figure 1 shows the path of the yarn in the yarn processing machine according to the present invention.

Figure 2 shows an example of filament yarn tension upon implementation of the method according to the invention.

The present invention comprises the steps of supplying the filament yarn to the processing unit (false twist method) using a false twist method while flowing a thread having a filament yarn tension force and processing the filament yarn by the processing device, at least A yarn processing method for producing one decorative yarn from one filament yarn, and a yarn processing machine installed for producing one decorative yarn from at least one filament yarn.

Thread processing devices (air-processing devices) for processing filament yarns with air-processing nozzles are also known. Such air-procurement is disclosed in German patent 39 09 516 A1. Pneumatic presses are used to permanently crimp soft and tissueless filament yarns. In this case, the plurality of supply chambers (center yarns) may be processed into decorative yarns that are over-delivery differently to form a textured yarn. In this process the filament yarns are uniformly crimped and optionally arranged around the feed chamber. The sheath may be composed of various decorative yarns. The filament yarns, i.e. the coated yarns and the core yarns, are fed to the air-processing nozzle via a delivery system, for example goderol. After the yarns have passed through the air-processing nozzle, the decorative yarn (multicomponent yarn) composed of a plurality of components is wound on a spool in which the multicomponent yarns are wound. The multicomponent yarns may be stretched again, fixed, shrunk and / or finished before winding up.

Thread mills for carrying out the flammable or flammable processes are also known. This method is also known as the torsion crimping method. In this case, the filament yarn has a so-called twist between the two pairs of cylinders, namely the delivery system and the winding system, by means of a twisting device, which is the capillary threads by heating the filament yarn using thermoplastic. Is fixed to. After cooling, crimping of the product, decorative yarn, occurs under the influence of the potential torsional force.

A disadvantage of the known thread processor is that the produced decorative yarn has a regular structure. However, in order to produce various types of fibers, it is preferable that the decorative yarns have an irregular structure. For example, this may have the effect of giving the impression that the decorative yarn produced or the fibers woven from it are handmade. In addition, the structure of the decorative yarn to be produced cannot be deformed sufficiently flexible during the manufacturing process.

European patent application EP 01 117 809 also discloses a so-called Fancyflex system. Fancyflex systems of this type have thread guides that produce inventory of the yarn to be processed at successive irregular time intervals. This thread stock is again fed into the path of the yarn to be machined in a cramped fashion. This results in a sudden interruption of the tensile force of the yarn to be processed, which interrupts the path of the yarn and affects the yarn after being processed.

It is an object of the present invention to avoid the problems of the prior art, and in particular to provide a yarn processing method and a yarn machine for producing a yarn by texturing, which can be used to produce a yarn having an irregular structure. .

This object is solved by the thread processing method and the thread machine described in the independent claims. The dependent claims represent preferred embodiments of the invention.

In the yarn processing method of the present invention for producing one decorative yarn from at least one filament yarn, the filament yarn is fed to the processing device while flowing the yarn having the filament yarn tensile force. The filament yarn is processed by a processing device. The basic component of the filament yarn tensile force is produced, for example, by placing a delivery system in the path of the yarn before the processing apparatus and after the leaving system. These yarn guides, ie delivery systems and take-off systems, run at different rotational speeds, producing the basic components of the filament yarn tension of the yarn flow. According to the present invention, the filament yarn tensile force is repeatedly reduced over time by repeatedly producing in each case a filament yarn stock that is repeatedly supplied to the path of the yarn before feeding the filament yarn to the processing apparatus. The filament yarn tension can be reduced repeatedly, for example, in each case by suddenly pulling the decorative yarn in the path of the yarn. That is, the filament yarn tension is initially increased compared to the base component. When the filament yarn is loosened again, the filament yarn tension suddenly collapses, so that the filament yarn stock is produced as desired and fed into the yarn path. As a result of passing the filament yarn through the processing apparatus at various filament yarn tensioning force, the produced decorative yarn has a structure that is somewhat stronger according to the filament yarn tension force.

The structure of the decorative yarn can be flexibly produced using the method according to the invention. The repeated reduction in filament yarn tension can be arbitrarily adjusted randomly by a suitable control system. Thus an entirely new decorator can be produced. A variable distribution of the material, ie a variable distribution of filament yarns over the length of the product decoration yarns can be obtained. Product decorators can have a sparking or cumulative effect, creating a completely new type of material.

A filament yarn tension variation module is preferably inserted before the heater to deflect the path of the yarn in the flow direction of the yarn and to create a feed of the yarn. If the filament yarn tension shift module is inserted before the cooler and / or after the cooler region, and / or after the cooler, the deflection towards the thread feed is in the direction of the thread's path or α ≦ 90 °. These measures can increase the stability of the process and affect the tensile strength of the yarn in the process. The various tensile force peaks for the yarns to be processed having different sizes and periods particularly affect the yarns to be processed.

The filament yarn tension is preferably reduced at irregular time intervals and / or at different strengths. Thus, the effect of giving a clear random variation on the structure of the product decoration yarn can be obtained.

The filament yarn stock is particularly preferably passed through the heater before being fed to the processing apparatus. As a result of the changed filament yarn tension, different parts of the filament yarn have different residence times in the heater. The irregular effect of decorative yarns produced in accordance with the present invention is enhanced by the filament yarns to be processed heated to different strengths, resulting in the various uses of filament yarn thermoplastics.

The process according to the invention consists of false twist texturing. Irregular effects of particular note can be achieved in the product decorative yarns by this processing method.

After the processing apparatus, at least one yarn, preferably filament yarn, may be fed with additionally flowing yarn having a constant filament yarn tension. In this case, the additionally supplied filament yarn may preferably pass through the entire production process, except that it does not pass through a module that changes the filament yarn tensile force (the filament yarn tension transition module). The yarn leaving the processing apparatus is twisted together with the supplied yarn.

The thread processor according to the invention is set to produce one decorative yarn from at least one filament yarn. The thread processing machine comprises at least one processing device, and thread guide devices installed on the air so that the thread can pass through the processing device while flowing a thread having a filament yarn tension force. According to the present invention, the thread processor has one or a plurality of filament yarn tension shift modules, which are located along the thread path before the processing apparatus on the thread machine. In this case, the filament yarn tension variation module (s), each of the filament yarn inventory that is repeatedly supplied to the path of the thread before feeding the filament yarn to the processing device at different time intervals and / or over-delivered amount, respectively In the case of repeated production is installed to repeatedly reduce the tensile force of the filament yarn over time. The thread guide device consists of one release system and at least one delivery system having different rotational speeds so that the basic components of the filament yarn tension can be produced. The thread processor according to the invention is installed to carry out the method of the invention. The advantages of the process according to the invention are thus realized with a thread machine according to the invention.

The filament yarn tensioning modules or modules are deflected in the direction of the path of the yarn to be positioned before the heater and / or before the cooler, and / or after the cooler area, or after the cooler to improve the quality of the processing or seal.

The combustible plant value is particularly advantageously composed of a Fancyflex device as the filament yarn tension shift module. Almost all filament yarn tensile profiles can be produced using a computer-controlled Fancyflex system. Thus, the desired irregular effect in the product decoration yarn can be obtained simply.

Next, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The accompanying drawings illustrate the subject matter of the present invention quite schematically and should not be construed as limited thereto. The individual elements of the object of protection according to the invention are shown so that their construction can be clearly shown.

1 schematically shows the flow path of a yarn in a yarn machine according to the invention. The filament yarn 1 first passes through the delivery system 2. At the end of the yarn path the filament yarn passes through the release system 3. The filament yarns can be composed of, for example, partially oriented yarns (POY) made of polyethylene terephthalate (PET) consisting of 36 filaments and having a fineness of 100 denier. The release system may have the same configuration as the delivery system. In order to form the basic component of the filament yarn tensile force, the filament yarn 1 is fed from the delivery system 2 to the production process at a lower speed than the filament yarn 1, or the product decorator is provided with the release system ( 3) is removed from the production process. The path of the yarn is further deflected by the various deflection rods 4. After the filament yarn 1 has passed through the delivery system, the filament yarn flows through the deflection rod 4 and then directly into the filament yarn tension transition module 5, ie preferably the Fancyflex unit. To pass. The path of the yarn in the filament yarn tension transition module 5 has an acute angle so that the filament yarn returns to another deflection rod 4 before being fed to the heater 6. In FIG. 1, the filament yarn tension shift module 5 is positioned horizontally (deflected in the yarn flow direction). The filament yarn tension shift module 5 may also be arranged before the cooler 7 and / or after the cooler 7 in the region of the cooler 7. In this region the yarn feed is deflected at the yarn flow direction and / or at an angle of? A plurality of filament yarn tension shift modules 5 may also be used. These different arrangements can affect the structure of the product decorator, as the shrinking supply of filament yarn stock in the path of the thread may be affected.

The heater 6 is equipped with a subsequent cooler 7. The filament yarn 1 is fed to the processing apparatus 10 after passing through the heater 6 and the cooler 7.

Figure 2 shows an example of filament yarn tension when carrying out the method according to the invention. The portion of the temporal profile for the tensile curve 20, ie filament yarn tensile force, is shown in a coordinate system composed of the tensile force axis 21 and the time axis 22. The tensile curve 20 is characterized by a basic tensile force and repeating peaks of different heights, that is, peaks of different intensities over irregular time intervals. Since the filament yarn tension is initially increased by the filament yarn tension shift module, ie the filament yarn is pulled in the path of the yarn, a stock of filament yarn is produced. When it is loosened again, the filament yarn tension repeatedly decreases with time in a convulsive type.

The method according to the invention can be carried out on individual filament yarns. The effect of the filament yarn tensioning module placed in front of the heater is a strong and irregular oscillation of the filament yarn tension in the path of the yarn and eventually in the processing equipment. Thus an irregular distribution of the material is obtained over the length of the product decorator. The profile of the tensile curve 20 shown results in this desired effect on the product decoration yarn. The profile can be generated using a computer-controlled filament yarn tension shift module. By modifying the software controlling the method according to the invention, the tensile curve can be made more flexible or optimized for various desired effects. For example, larger interruptions can be introduced between each of the two tensile peaks. The operation of the operator can be improved, for example by using different thread guides, eg open seal guides, for example using so-called wolf-teeth profiles instead of closed seal guides, or Improved manipulation of the operator can be obtained by better bending the outer surface that the filaments contact.

The method according to the invention can alternatively be combined with various manufacturing methods for application to a single filament yarn.

-Two POY PET yarns can be processed together from different POY spools. The two seals can be joined immediately after unwinding from the spool. One of the yarns can pass through the filament yarn tension shift module, while the other yarn is maintained at a constant yarn tension. Both yarns may be used together after the processing unit.

Two POY PET yarns are used, one of which passes through a standard machining process and the other passes only through the filament yarn tensile transition module, the two yarns being joined together, for example by interlacing Can be.
