Abstract

Woven carpet is has two visible surface zones (6, 7) that form the patterning. The ratios of spun yarn (1) to continuous filament yarn (2) differs in each of the two zones (6, 7). Preferred Features: The different appearances in the two surface zones (6,7) are through a spun yarn (1) with an S-twist and a continuous filament yarn (2) in a Z-twist, in different proportions in each zone (6,7). With a pile carpet, the pile formations differ in the two surface zones (6,7).

Description

State of the art

Both floor carpets and tapestries are predominant for aesthetic reasons with a more or less rich pattern - a so-called carpet pattern - Mistake. In particular for large-scale floor carpets, such as those for example in public buildings, banks, insurance companies, conference rooms, Wide-bodied aircraft, etc. are used, rather quiet, subtle patterns preferred, which gives the carpeted interiors an elegant look Give appearance. Such patterns are usually proportional predominant surface area on the visible side of the carpet in a uniform, uniform color and structure. This surface area is as follows referred to as the background of the pattern. That contrasts with the background Motif of the pattern can be a comparative one with calm, subtle patterns Take up a small surface area on the visible side of the carpet.

It has long been known to use motifs to create patterns in carpets of the pattern with a different color than the background of the pattern. However, such a two-colored or multi-colored visible side is particularly effective large-scale carpets often restless and not very elegant.

That is why large carpets that give a room a subtle, elegant look To give the appearance, visible sides with a uniform color (i.e. plain colored visible sides) prefers. In order to provide a pattern even for carpets in a uniform color create, it is known for the background and the motif of the pattern different To use weaves. This makes one with plain-colored carpets subtle pattern tone on tone achieved. However, it has been shown that there is a distinction of the motif from the background of a pattern due to different Weaves are often difficult to identify. This is particularly the case for heavily used vehicles Carpets, for example in aircraft, are pronounced the case where through the intensive use after a short time no visible difference between the background and the motif of the pattern can be seen more.

Presentation of the invention

The object of the present invention is to create a woven carpet with a pattern tone on tone, in which the pattern even after heavy use of the carpet is still clearly and clearly visible.

The solution to the problem is the subject of the independent claims.

According to the invention, a woven carpet with a first surface area is distinguished on the visible side of the carpet, the appearance of which forms a Pattern from a second surface area on the visible side of the carpet differs in that to create the different appearance (in visible yarn on the carpet surface) the proportional ratio of spun yarn for continuous yarn in the first surface area different from the proportional Ratio of spun yarn to continuous yarn in the second surface area.

Spun yarn is a yarn that is made up of comparatively short fibers is spun together. Most natural fiber yarns are spun yarns. Spun yarns can, however, also be made from plastic fibers if they are in cut short pieces and then spun them together. Spun yarns have a somewhat rough, fibrous, "textile" surface due to the fiber ends on. In contrast, continuous yarn is a yarn that essentially consists of Continuous fiber is composed. Continuous fibers are based on the English Description "bulked continuous filament" also as BCF fibers and continuous yarn referred to as BCF yarn. Continuous yarns mostly consist of synthetic fibers and have a smooth surface compared to spun yarns.

Under the proportional ratio of yarn (with a certain property) in A surface area on the visible side of a carpet is in the course of the present Description and claims of the visible surface portion of the surface area to understand who is covered by this yarn.

In a preferred embodiment of the invention, the difference is in appearance between the first surface area and the second surface area even exclusively on the fact that in the first surface area in relation to the second surface area the proportional ratio of spun yarn to continuous yarn is different.

The larger is advantageously used for the large-area background of the pattern Proportional ratio of spun yarn to continuous yarn used as for the small area Motif of the pattern.

In a variant of the invention is a woven carpet with a first surface area on the visible side of the carpet, the appearance of which forms a Pattern from a second surface area on the visible side of the carpet differs, designed such that to create the different appearance (in the visible yarn on the carpet surface) the proportional ratio of Yarn with twist twist S to yarn with twist twist Z in the first surface area different from the proportional ratio of yarn with twist S to yarn with Thread twist Z is in the second surface area. In a preferred embodiment this variant of the invention is based on the difference in appearance between the first surface area and the second surface area even exclusively on that in the first surface area with respect to the second surface area the proportional ratio of yarn with twist S to yarn with twist Z is different.

In contrast to screw threads, where there is a left-hand thread and a right-hand thread is spoken - the twist depending on the direction of rotation referred to as either twist S or twist Z.

In the case of loop carpets, the difference in the ratio of yarn with a twist is S for yarn with twist twist Z with long pimples (floating pimples) more recognizable than with short pimples, because the pimples made of yarn with twist S topple differently than the knobs made of twisted yarn Z. Therefore, the embodiment of the invention, in which the proportional to generate the different appearance Ratio of yarn with twist S to yarn with twist Z in the first surface area different from the proportional ratio of twisted yarn S for twisted yarn Z is in the second surface area, preferably applied to carpets with a long pile.

In a further preferred embodiment of the invention are in the first surface area with respect to the second surface area, both the proportional Ratio of spun yarn to continuous yarn as well as the proportional ratio of Yarn with twist twist S is different from yarn with twist twist Z. Preferably is the difference in appearance between the first surface area and the second surface area even exclusively on that in the first surface area compared to the second surface area, both the proportional Ratio of spun yarn to continuous yarn as well as the proportional ratio of Yarn with twist S are different from yarn with twist Z.

The invention provides a woven carpet with a pattern that Even after heavy use of the carpet, it is still clearly visible is. Neither the difference in appearance from spun yarn to continuous yarn, nor the difference in the appearance of twisted yarn S becomes twisted yarn Z affected by the use of the carpet. So it’s not absolutely necessary in the case of a carpet according to the invention, the motif of a pattern with another Color to be used as the background of the pattern. Rather, the invention enables creating a pattern tone on tone that is still clearly and distinctly recognizable and it remains even after intensive use of the carpet.

In the case of a carpet according to the invention, the visible yarn in the first preferably has Surface area the same uniform color as the visible yarn in the second Surface area.

In a further preferred embodiment of the invention, the fibers are made of visible yarn in the first surface area even from the same fiber material like the fibers of the visible yarn in the second surface area. With the fiber material can be any of the common carpet fiber materials, such as Wool, camel hair, cotton, silk, polyamide or any other plastic or Trade natural fibers.

According to a further embodiment of the invention, the woven Carpet around a loop carpet, in its manufacture by inserting rods a pile cover is formed between the base fabric and the pile warp threads is also known as a rod carpet. Because pull rods are used, it acts around a rod carpet with a pile of closed loops. Further it is preferred that the rod carpet with closed loops (also knobs called) according to this embodiment of the invention, the type of pole binding in the first Surface area different from the pole bond type in the second surface area is. Preferably based on a carpet according to this embodiment of the invention the difference in appearance between the first surface area and the second surface area even exclusively on that in the first surface area compared to the second surface area, both the proportional ratio from spun yarn to continuous yarn as well as the proportional ratio of yarn with twist twist S to yarn with twist twist Z as well as the type of pile weave are.

In the case of a woven carpet according to a further preferred embodiment of the Invention is the proportional ratio to create the different appearance from a first yarn from a first multiple thread to a second yarn a second, different from the first multi-ply in the first surface area different from the proportional ratio of the first yarn to the second Yarn in the second surface area. The first yarn can for example consist of a triple thread and the second thread consist of a four-ply thread. At a Carpet according to this embodiment of the invention can be a rod carpet trade with a pile of closed loops. Preferably based with such a carpet the difference in appearance between the first one Surface area and the second surface area even exclusively on that both in the first surface area compared to the second surface area the proportional ratio of spun yarn to continuous yarn as well as the proportional Ratio of yarn with twist S to yarn with twist Z as well the proportional ratio of the first yarn to the second yarn as well as the type of pile weave are different.

The following detailed description of an embodiment of the present In connection with the accompanying drawing, the invention serves only as an example of a better understanding of the invention and is not intended to limit the scope of the claims. For those skilled in the art are from the following Description in conjunction with the accompanying drawings and the entirety of the claims further advantageous embodiments and combinations of features readily recognizable, but still within the range of present invention.

The drawing represents a preferred embodiment of the present invention. It shows:

Fig. 1

a simplified schematic representation of a cross section along a warp line through part of a carpet according to a preferred embodiment of the invention.

Ways of Carrying Out the Invention

In FIG. 1, a part of a woven is shown in a simplified schematic representation Carpet shown according to a preferred embodiment of the invention. In the cross-sectional representation along a warp line are only the pole chains, the top and Shots shown as well as the draft rods. The rest, for the representation of the Invention of other essential components of the carpet (such as binding chains, Filling chains etc.) have been shown in FIG. 1 for reasons of clarity omitted. In Figure 1, the carpet is at one point during manufacture of the carpet, shown, on which those used to manufacture the carpet Grid 5.1 - 5.10 still between the pile threads 1, 2 and the base fabric of the Carpet (not shown) are registered. These are used during the weaving process continuously pulled out of the carpet fabric and are at the finished carpet not available anymore.

The carpet, a section of which is shown in FIG. 1, is a two-loom rod weave, which is on a jacquard-controlled weaving machine was manufactured with a fleet e-center. The upper shots 3.1 - 3.10 and the lower shots 4.1 - 4.10, which are perpendicular to the sheet plane of Figure 1, are in the Cross-sectional representation of Figure 1 shown as squares. In the case of carpet production Rods 5.1 - 5.10 used are pull rods, so that the Carpet has a pile of closed loops. The cross section of the Figure 1 loops are formed by the pile threads 1, 2. The two Pole threads 1, 2, to the pile warp line shown in the cross-sectional view of Figure 1 belong to a different choir of the two-loom weaving machine.

The pile threads of the two choirs of the carpet shown in FIG. 1 are each made a different thread. The first pile thread 1 and all threads of the Corresponding choirs are made from a pile yarn made from a polyamide spun fiber in 3-ply thread. It is therefore a spun yarn. The Spun yarn of the first pile thread 1 is provided with a twist S. In contrast are the second pile thread 2 and all threads of the corresponding choir a pile yarn made from a polyamide continuous fiber in 4-ply thread Thread twist Z exists. Otherwise there are no differences between the pile yarns of the two choirs. In particular, they do not differ in terms of their Color still in terms of the fiber material from which they are made. It is about in both cases around polyamide fibers, which is essential only in the case of spun yarn are shorter than in the case of continuous or BCF yarn.

1 shows three different surface areas 6, 7, 8 visible on the visible side of the carpet. The first surface area 6 corresponds to this Background of the pattern on the visible side of the carpet. In the cross-sectional view 1, the first surface area 6 is divided into two partial areas, which however related in the plane on the visible side of the carpet. In horizontal The one partial area of the first surface area 6 extends in the direction about the top shots 3.1, 3.2, the rods 5.1, 5.2 and the bottom shots 4.1, 4.2. The other partial area of the first surface area 6 extends over the top wefts 3.9, 3.10, the rods 5.9, 5.10 and the shortfalls 4.9, 4.10. The second Surface area 7 corresponds to the motif of the pattern on the visible side of the carpet. It extends over the top shots 3.4, 3.5, 3.6, 3.7, 3.8, rods 5.4, 5.5, 5.6, 5.7, 5.8 and the shortfalls 4.4, 4.5, 4.6, 4.7, 4.8. 1 a third surface area 8 can be seen, which is at a boundary between the first Surface area 6 and the second surface area 7 is arranged and extends over the top 3.3, the tail 5.3 and the bottom 4.3.

In the first surface area 6, the first pile thread 1 runs under an excess 3.1, over the next rod 5.1, under the next upper shot 3.2, over the next Tail 5.2, etc. Due to the type of pole binding in the first surface area 6 short Nubs formed from the first pile thread 1. The second pile thread 2 runs in the first Surface area 6 invisible under the top shoots and rods.

In the second surface area 7, the first pile thread 1 runs under an excess 3.5 and the next rod 5.5, over the next upper shot 3.6 and the next Tail 5.6, under the next top shot 3.7 and the next tail 5.7 etc. The second pile thread 2 runs alternately to the first over the top 3.5 and the next rod 5.5, under the next upper shot 3.6 and the next rod 5.6, over the next top shot 3.7 and the next rod 5.7 etc. By the type of pole binding in the second surface area 7 long nubs are alternately formed the first pile thread 1 and the second pile thread 2. These long pimples are also used as floating nubs and the type of pile binding in the second surface area referred to as floatation.

Both the first pile thread 1 and the run in the third surface area 8 second pile thread 2 under a top weft 3.3 and the next tail 5.3. This type of pole binding is also known as an empty space.

The two pile threads 1, 2 always run over in all three surface areas the deficits 4.1 - 4.10.

In the representation of Figure 1, the three surface areas 6, 7 and 8 through three different types of pole binding. The first surface area 6 differentiates further from the second surface area 7 through the visible one Surface recognizable portion of yarn of the type of the second pile thread 2: this Proportion is zero in the first surface area 6, while it is in the second surface area 7 is approximately half.

Overall, the difference in appearance is based on the carpet shown in FIG between the first surface area 6 and the second surface area 7 that in the first surface area 6 compared to the second surface area 7 both the proportional ratio of spun yarn 1 to continuous yarn 2 as well as the proportional ratio of yarn 1 with twist S to yarn 2 Thread twist Z as well as the proportional ratio of yarn 1 with a 3-fold Thread to yarn 2 with a 4-ply thread and the type of pile weave are different.

In summary, it can be stated that the invention provides a woven carpet with a pattern is provided, which can be carried out tone on tone and itself is still clearly visible after heavy use of the carpet and stays.
