EP0861931A1 - Method and device for the production of the yarn from at least two yarn components - Google Patents

Abstract

To produce a yarn, from at least two yarn components, before they are brought together at least one yarn component is processed differently from the other, or the other component is given a special treatment or is of a different type. Also claimed is an assembly where one yarn component passes through at least two processing stages, which are used selectively. At least one stage is for compaction.

Description

The invention relates to a method for producing a yarn from at least two Yarn components, the yarn components before a collection stage in a last one Treatment stage can be compacted together into a yarn, as well as a plant for creating a yarn from at least two yarn components.

One method and one is known from European Patent Application No. 0434 601 A1 Device for producing untwisted yarn from at least two relative to one another known fibril bundles in which the fibril bundles, here called yarn components, each separately before stretching in each treatment stage treated to be textured together after stretching. After general knowledge, the textured yarn is then swirled to the fluffy type of yarn through texturing into a processable one To form yarn. The treatment level consists of one before stretching False twist or intermingling stage around the individual fibrils of the yarn components to compact in order to get the possibility to change the distances between the to keep individual yarn components as small as possible without creating marginal fibrils intertwine of the individual yarn components and thereby cause faults or at least can lead to a mixture of the yarn components.

A method and a method are known from another European patent specification EP 485 871B1 Device known to produce a textured multicolor yarn, the individual colors spun separately from a spinning beam and cooled are then each separately via an oiling and then each to be passed separately through swirl nozzles. The swirling happens in such a way that they are at least as much as possible during the subsequent stretching is dissolved again. The purpose of swirling is to compact the individual bundles of fibrils, also called yarn components, if possible avoid that the individual fibril bundles with different colors interlock interweave to disturb the color separation in the end yarn. The stretched Fibril bundles are then immediately put together in a texturing nozzle textured, chilled and swirled together in a swirl, afterwards to be wound up. The latter vortex is a collective compacting i.e. a stitching of the three threads around an actual coherent, to produce windable yarn.

From the European patent application with the publication no. EP 0 784 109 A2 it can be seen that different types of partial threads, for example different colored or differently dyeable partial threads either from spinning beams or from Coils are delivered and each oiled before stretching and then be precompacted to either together in one after stretching or to be textured individually in a texturing device. After the texturing device the plug emerging from the texturing device is cooled, whereby the cooling already within the texturing device, towards the exit end of the Texturing device out, can happen at least partially.

After cooling the graft, the partial threads are each individually in a post-compaction preferably swirled around then together i.e. summarized to be swirled again in a collective compaction to get out of the Partial threads to form a windable yarn.

There are different types of texturing devices, as well as devices for Production of a corresponding yarn shown and described on which the Description of this application is related, which is why EP 0 784 109 A2 as integrating Part of this registration applies.

The object of this invention is to guide the individual yarn components and the treatment of these yarn components up to the common compacting stage to guide the yarn components clearly and predeterminably in order to follow the common compacting stage to influence the resulting yarn character.

According to the invention, this object is achieved in that at least procedurally a yarn component at least one treatment stage known per se passes through before this yarn component together with the further one or more treated or untreated yarn components the last treatment stage passes through, in order to then be collected as yarn in the collecting stage, during the plant at least two treatment stages for at least one yarn component are available, which can be used optionally and at least one Compacting stage and a collecting stage for one of at least two yarn components existing yarn is provided.

The yarn components can be freshly spun and drawn or act as drawn yarn components drawn from a spool. Likewise the yarn components can already be precompacted in the form of a swirl or have experienced a wrong turn.

The yarn components can also have other and different properties have, be it in relation to the type and / or structure and / or the color of the Yarn components. The type is based on differences in titer or in number Fibrils of yarn components or in polymer or in dyeability or in Cross section of the fibrils or the additives in the fibrils and the structure are on Changes or differences in the crystalline or molecular structure relates.

However, there is still the possibility of untreated in the sense of the invention Yarn components with treated yarn components in the common compacting stage in order to influence the character of the yarn in this way

In addition, a staple yarn can also be used as an untreated yarn component, be it from synthetic or natural fibers spun, which is understood before Collection level, i.e. winding out the finished yarn together with the others Yarn components is compacted compactly.

The treatment of the individual yarn components can be any known texturing, any known swirling, any known false twist or any other known method which in the yarn component an aforementioned type and / or structural change and / or causes a change in shape of the individual fibrils of the yarn component.

Since the yarn components mentioned, with the exception of the staple yarn components mentioned, are already stretched yarn components, the individual yarn components in an immediately following, also called "on-line", Treatment according to the invention, each separately textured, for example and compacted together after texturing, preferably swirled, to thereby produce a yarn ready for winding.

It is also possible to use texturing nozzles of the same type with different gas pressures or different temperatures or different amounts of gas per Time unit can be loaded or there is also the possibility for at least a yarn component to choose a different texturing nozzle, which also can be operated differently in the aforementioned manner.

There is also the possibility of a thread tension described later by means of the figures the individual yarn components before and / or in the common compacting to keep different in order to follow variations of the yarn character of compaction.

Furthermore, the individual can be guided later as described by means of the figures Yarn components in the compaction are kept different on this Way the influence of the compacting on the individual yarn component differently and thus an influence on the yarn after the compacting component receive.

Another variant is that at least one treated yarn component with at least one untreated yarn component in the common compacting stage is combined into a yarn, thereby the character of the yarn after the compacting stage.

Basically, it should be mentioned that the yarn components are separated from each other until Collective compacting level are carried out, in order to have as many possible influences to get the finished yarn after the collective compaction to either to simplify the process or to change the character or structure of the finished yarn can still get different, even within the process Yarn components are passed through a treatment stage together.

The invention is neither to the mentioned treatment means nor to those mentioned Compacting means limited, but any treatment or compacting means are used to carry out the method.

The invention is therefore not restricted to the elements shown and described.

The invention is shown with reference to FIGS. 1 to 20, for example and purely schematically and briefly described below.

In Fig. 1, the row marked with 1 relates to a yarn component template, each template being either an on-line from a spinning beam drawn or a drawn yarn component coming from a bobbin can be.

The number 2 denotes a number of treatment stages, whereby as from 1 shows that each yarn component has its own treatment stage.

3 denotes a common compacting stage which, as can be seen from FIG. 1, all yarn components 5 to 5.4 are summarized and then treated pass on as yarn 7 of collection level 4. At this collection level 4 it is a winding device.

2 is intended to show that the individual yarn components have no or no more can go through as a treatment step before the individual yarn components in the compacting stage 3 together to form a yarn 7.1.

The yarn 5 is by means of one treatment stage, the yarn 5.5 by means of two treatment stages and the yarn 5.6 is provided without treatment stages.

Furthermore, the yarn component 5.6 can either be a multifilament yarn or be a staple yarn or any other non-multifilament yarn.

The multifilament yarn can be an already textured or otherwise treated Trade yarn or any yarn of any yarn characteristic which is useful in one compacting stage together with at least one other Yarn component to be compacted.

If, as previously mentioned in Fig. 2, the yarn component 5.6 as a variant is a thread template not to be treated further, which with other thread components can be compacted, so it is usually the yarn templates 1 um yarn components, which may already be pre-compacted, usually stretched, but usually not textured, so the first Treatment level 2 for such yarns is texturing.

A further treatment step can then be carried out for a yarn component, as shown in FIG. 2 2.1 can be provided, for example, a so-called post-compaction is before this yarn component with the other two yarn components is combined into a yarn 7 in the collective compaction.

There is also the option of collective compacting two or more times perform what is shown in Fig. 2 with the dashed rectangle, designated 3.1 is shown.

The same applies if treatment stage 2.1 involves post-compaction acts, i.e. that such post-compaction is also done two or more times can be carried out, which also applies to collective compacting 3.1.

If treatment level 2 is texturing, any of these can be known texturing devices or texturing methods used will. The way of the method or the device of texturing is not the subject of this invention.

The same applies if treatment level 2 or 2.1 or 3 or 3.1 is concerned a swirling stage is concerned, any swirling methods known per se can be used or devices are used, since such methods and devices are not the subject of this invention.

The same applies if treatment levels 2 or 2.1 or 3 or 3.1 are concerned False twist levels are involved, any false twist levels known per se can can be used since they are not the subject of this invention.

The same applies to collection levels, i.e. there can be known winding devices or other collection levels not mentioned here.

It is also free to use the aforementioned treatment or collective Compacting levels due to variations in the equipment, for example with texturing nozzles by variations in the temperature, the amount (kg / h) and the pressure of the treatment gas operate differently.

3 shows an example of a swirl nozzle used as the compacting stage 3 or 3.1. This swirling nozzle corresponds to a swirling nozzle known per se the Heberlein company in Wattwil, Switzerland. However, it is understood that as mentioned earlier around any swirl nozzle or even one False twist nozzle of any make can act.

In Fig. 3 is the swirl nozzle with 6 and a passage opening with 9 and the entering Gas marked with 8.

Seen in the running direction of the yarn components, the intermingling nozzle 6 is a guide ring 11 upstream, which serves to guide the yarn components 5 to 5.6, around them, as shown in FIG. 4, in different positions in the passage opening 9 of the swirling nozzle 6 in order to thereby different swirling effects on the corresponding yarn components 5 to 5.6. Here are for example 3 yarn components shown, which are basically at least two and also to be any of the previously mentioned yarn components can.

The guide ring 11 can be moved as shown with the displacement directions 12 to change the positions of the yarn components in the passage opening.

There is also the possibility of the average opening 16 of the guide ring to be given either a circular or an oval or some form, thereby different positions of the yarn components in the passage opening 9, provided that the guide rollers 11 upstream of the guide ring themselves are not changeable in their position, the position of the yarn components 5 to 5.6 in the passage opening 9 together with the guide ring 11 change.

With pinch rollers 14, which lie opposite the guide rollers 13 and together with these can form a pair of pinch rollers, it should be shown that in combination with a draw-off roller pair 15 provided after the swirling nozzle 6 the tension in the yarn components 5 to 5.6 are kept different can.

This thread tension in the individual yarn components alone or in Combination with the different position of the yarn components to achieve a to obtain different yarn character of the yarn 7.

Fig. 4 shows the top view of the swirl nozzle 6 according to the lines I-I.

In Fig. 4, the yarn components are 5 to 5.6 with an example of 3 yarn components shown. Likewise, the gas inlet with the gas 8 is shown as it is in connection represented with swirling nozzles from the aforementioned Heberlein company becomes.

Figures 5 to 20 show variations in the use of the treatment levels for treating the same or different yarn components.

The treatment levels are already in the European patent application with the Number EP 0 784 109 A2 shown and described, which is why this document is an integrating It is part of this registration.

Figures 5 to 20 are partially provided with the same reference numerals as the figures 1 and 2, which together with Figures 3 and 4 already in the previous Swiss patent application No. CH 0441/97 shown and described are.

The squares marked with 1 are either yarn component templates from continuous filament bundles, either from a spinning beam or come from a bobbin or a thread from stacked yarn, which either can be spun from synthetic or natural fibers.

The squares marked with 2 relate to one in the aforementioned European one Patent application EP 0 784 109 A2 pre-compacting shown and described, while with 2.1 a texturing treatment stage, with 2.2 a post-compacting treatment stage is marked, which is also in the aforementioned Euro application are included.

Those shown and described in the aforementioned European patent application and there with a 4 marked stretching zones between the pre-compacting treatment stage and the texturing treatment level as well as those in the aforementioned European Patent application with 33, 34 and 35 marked stretching rollers are not drawn here for the sake of simplicity, the latter corresponding to the Description of the aforementioned European patent application are optional, wherein the stretching zones marked with 4 for yarn components from spools as well can be omitted.

As already mentioned at the beginning of this application, all treatment stages can be specified operated differently, thereby variations in yarn character or in the fabric made therefrom, for example a carpet.

5 shows with A1 that a filament bundle from the spinning beam in a pre-compacting treatment stage 2 is treated and together with a filament bundle A2, which comes from a bobbin with pre-stretched filament in the collective compaction treatment stage 3 compacted and then as yarn 7 in a gathering stage, for example, a winding device.

Instead of a bundle of filaments from a spool with pre-stretched synthetic filament can either be a synthetic or a natural fiber staple yarn together with the filament bundle of the spinning beam in the compacting stage 3 compacted and as Yarn 7 can be wound up in collection stage 4.

Basically, the yarn components are always in collective compaction level 3 grouped together before the collecting stage 4 to form a yarn 7, which is why the others Description relating to figures dispenses with the repetition of these functions becomes.

The difference between Fig. 6 and Fig. 5 is that the spinning beam Coming filament bundles A1 after the pre-compacting stage 2 another texturing stage 2.1 runs through this filament bundle with the yarn component of the bobbin A2 is led to collective compacting level 3.

FIG. 7 shows that the filament bundle A1 coming from the spinning beam opposite 6 additionally after the texturing stage 2.1 in the post-compacting stage 2.2 is compacted before this filament bundle with the yarn component the coil A2 reaches the collective compacting stage 3.

The. 11 shows, compared to FIG. 10, the variant that the right-hand filament bundle A1 additionally after pre-compacting level 2 through texturing level 2.1 is performed before the two filament bundles in the collective compacting stage 3 to one Yarn 7 are merged.

Fig. 12 shows a filament bundle or staple yarn of a bobbin A2, the staple yarn can exist either as synthetic fibers or natural fibers, which with two filament bundles of Fig. 8 or 9 or 10 or 11 in the collective compacting stage 3 compacted into a yarn 7.

13 shows three filament bundles A1, each originating from a spinning beam, the right-hand filament bundle all treatment stages 2,2.1,2.2 before the collective compaction stage 3 passes through alone while the left and middle filament bundle after precompacting stage 2 and texturing stage 2.1 together through the post-compacting stage 2.2 and then together with the right-hand filament bundle in the collective stage 3 compacted into a yarn 7 to become.

Basically, _“ right-hand filament bundle” is to be understood as the one that is shown in the corresponding figure with a view of the figure on the right of a corresponding middle or corresponding “left-hand filament bundle”.

FIG. 14 shows, as a variant of FIG. 13, that the left-hand and middle filament bundle After precompacting stage 2, textured together in stage 2.1 and then in stage 2.2 is compacted again with the right-hand filament bundle, which is carried out through all treatment levels 2 to 2.2, in the collective compacting level 3 to be compacted into a yarn 7.

Fig. 15 shows the combination of a filament bundle A2 made of either synthetic fibers or natural fibers, which in the collective compacting stage 3 with filament bundle 13 or 14 is collectively compacted to obtain a yarn 7.

16 shows three filament bundles A1, each from a spinning beam, the right-hand side Filament bundle goes through all treatment stages 2 to 2.2 alone while the middle and left-hand filament bundles precompacted together in treatment stage 2 is then used as a precompacted bundle of filaments textured in stage 2.1 and to be compacted in stage 2.2 before this common filament bundle with the right-hand filament bundle in the collective compacting stage 3 is compacted into a yarn 7.

17 shows four filament bundles A1, each originating from a spinning beam, whereby the two right-hand filament bundles are precompacted together in stage 2 then as a common filament bundle through the texturing stage 2.1 and then through the post-compaction stage 2.2 before this common filament bundle with the two filament bundles on the left a yarn 7 can be compacted collectively. The two left-hand filament bundles each pre-compacted in stage 2 to work together in stage 2.1 textured and to be compacted together in level 2.2 to be as a common Bundles as mentioned above with the common right-hand filament bundle to be compacted collectively in level 3.

18 also shows four filament bundles originating from a spinning beam A1, the left-hand filament bundle going through all stages 2 to 2.2 alone, before this with one from the adjacent single filament bundle Triple filament bundle combined filament bundle in the collective compacting stage 3 is compacted into a yarn 7. The triple filament bundle settles on the one hand from a single filament bundle A1 and one from two single filament bundles A1 summarized double filament bundle together, the Single filament bundle on its own and the double filament bundle together through a precompacting stage 2, and then together through the texturing stage 2.1 and then through the post-compacting stage 2.2 are then together in the stage before collective compacting 3 2.2 to be compacted.

19 shows on the right-hand side two yarns A2 of one bobbin each, one bobbin a staple yarn with synthetic fibers and the other spool A2 a staple yarn with natural fibers can have or both bobbins have different synthetic staple yarns or different natural staple yarns. The summarized Stacking yarn in collection stage 3 either with the filament bundles of FIGS. 16 or 17 or 18 as a combined filament bundle in the collective compacting stage 3 is compacted into a yarn 7.
