EP1408143B1 - Carpet made on a pile wire loom - Google Patents

Abstract

The woollen pile yarns have a thickness of Nm 4 - 10 (250 - 100 tex) and the pile nep (2) count amounts to 120,000 - 200,000 per m2 of carpet. The pile height is 2 mm or less and yarn consumption per pile warp is 600 - 1000 g/m2 of carpet. The carpet incorporates two yarns systems that intersect at a right angle and at least 34 rows of pile neps (3) per 10 cm in the direction of the transverse yarn system.

Description

The invention relates to a rod carpet with two right angles crossed thread systems, the longitudinal thread system from a pile chain integrated into a basic fabric, a binding chain and a basic chain and the transverse one Thread system consists of the weft threads, the threads of the Base and tie chain with the weft threads the base fabric form. Such a rod carpet with a pile of wool is known from US-A-2 571 860.

When weaving a rod carpet, two thread systems are used crossed at right angles. The longitudinal threads become warp called, while with the transverse threads of the Weft speaks.

The longitudinal threads are called a pile chain, tie chain and Designated basic chain. The binding chain connects the transverse ones Weft threads with the longitudinal pole and base chain. The basic chain forms the foundation of the rod carpet.

The weft threads are alternated across the base chain as Shortfall or upper shot. The weft threads form together with the threads of the binding and basic chain the base fabric of the rod carpet. The weft threads exist especially made of jute, polypropylene, glass fiber, polyester, Cotton and blends of the aforementioned fibers.

The threads are used to make the rod carpet Basic and binding chain formed a simple compartment in which the weft thread is entered by the shooter. At the same time, the pile-forming pile threads form a second Compartment, in which a fixed one above the weft Rod, the rod, is entered. If now with the next Weft entry just made a simple compartment and the pile thread is integrated in the base fabric, it forms over the Tail a noose that remains raised when after some more weft and rod entries the first inserted rods pulled out again in the weft direction become.

Are these rods not round and smooth, but on provided with a cutting knife at the ends Pull out the pimples formed by the loops cut open so that a velor carpet is created. Becomes while using a smooth-walled rod, the pimples remain receive. A bouclé carpet is created.

According to the method described above, the applicant has been making rod carpets for about 30 years, the thread density in the direction of the longitudinal thread system being 28-34 pile threads per 10 cm, 33 rows of pile knobs per 10 cm being arranged in the direction of the transverse thread system. This results in a maximum number of polnubs of 112,000 per m ² . The pile threads of the well-known rod carpet are made with carded or semi-worsted yarn from polyamide fibers or from endless polyamide threads. The thread size of the pile threads produced in this way is in the range from Nm 3 to 6 (Nm =: number metric) ≈ (333 tex - 167 tex). This well-known rod carpet achieves an object suitability, the classification of which according to the test standard EN 1307, which is generally applicable to carpets made of polyamide fibers, gives the overall rating "extreme".

The disadvantage of the known rod carpet is the appearance from Pilling. Pilling refers to small nodules that are by walking, rubbing, rubbing or wrong Clean up on synthetic fabrics.

The invention is based on this prior art the task is based on a rod carpet of the aforementioned Type to create the classification according to the test standard EN 1307 "extreme" achieved in the overall assessment and at which prevents the pilling effect.

• dass die die Polkette bildenden Polfäden ausschließlich aus Wolle bestehen,
• die Polfäden eine Garnstärke von Nm 4,0 - 10,0 (250 tex - 100 tex) aufweisen
• die Polnoppenzahl zwischen 120.000 und 200.000 Polnoppen je m² des Rutenteppichs beträgt,
• die Polhöhe kleiner oder gleich 2 mm ist und
• der Garneinsatz der Polkette (P) zwischen 600 - 1000 Gramm je m² des Rutenteppichs beträgt.

This object is achieved in the rod carpet of the type mentioned at the outset by

• that the pile threads forming the pile chain consist exclusively of wool,
• the pile threads have a thread size of Nm 4.0 - 10.0 (250 tex - 100 tex)
• the number of poles is between 120,000 and 200,000 poles per m ^{2 of} the rod carpet,
• the pole height is less than or equal to 2 mm and
• the yarn use of the pile chain (P) is between 600 - 1000 grams per m ^{2 of} the rod carpet.

Because the pile-forming pile threads consist exclusively of wool, the undesirable pilling effect is effectively avoided.

The use of wool not only eliminates the pilling effect, but is also from an ecological perspective advantageous because the wool used is a renewable natural textile raw material. For the The production of rod carpets is only suitable a robust and resistant wool, such as New Zealand wool. The carpet pile of the invention Rod carpet recovers even under extreme stress extraordinarily fast, so that always an even Appearance is guaranteed. The use of wool bears in addition to the moisture balance of the indoor air. This effect is due to the ability of the wool to Attributed to moisture absorption. After all, that is Carpet according to the invention heavier for a given object suitability flammable and thus compared to conventional carpets in this class safer.

The suitability for the object is achieved by the pile threads of the pile chain having a yarn size of Nm 4 to 10 (250 tex-100 tex), the number of pile nubs per m ² compared to the known rod carpet to at least 120,000 nubs per m ² , but no more than 200,000 nubs, while simultaneously reducing the pole height from 2.2 mm to a pole height </ = 2 mm. The pile height is the distance from the highest point of the cut or drawn pile nubs to the base fabric. Surprisingly, it has been shown that reducing the pole height not only results in a particularly good pole position, but also has a favorable influence on the load-bearing capacity of the rod carpet. For the extreme loads of the rod carpet according to the invention, the yarn use of the pile chain is between 600 to 1000 g / m ² .

The increased number of poles is preferably achieved by that deviates from the previously common reed setting Reed setting of more than 34 reed / 10 cm, preferably 40 Riet / 10 cm is chosen. From this reed setting follows a thread density in the direction of the longitudinal thread system, which are larger than 34 pile threads per 10 cm, in particular 40 pile threads is 10 cm each. In the direction of the transverse thread system to arrange so many rows of studs that after the Main claim required number of polnubs of at least 120,000 is achieved.

In the direction of the transverse thread system are preferred to arrange at least 34 rows of polnubs each 10 cm. at Compliance with this lower limit is the thread density in To increase the direction of the longitudinal thread system accordingly, to achieve the required number of poles.

The pole knobs can be drawn in a manner known per se Loops or cut nubs his. In addition, it is possible to go through the rod carpet the combination of drawn loops and cut knobs to give a structure.

The rod carpet is preferably woven in a two-weft weave. However, a three-shot binding is also conceivable. in the In the first case, two weft entries are used to form a pimple needed, in the second case three.

A rod carpet woven using the shaft-rod method either plain or striped in the warp direction. For the production color-patterned goods, it is necessary that each individual thread of the pile chain individually and independently can be raised and lowered for pattern formation. The requirement to control every thread by itself, is made by making the rod carpet after the Jacquard rod weaving process fulfilled.

The invention is described below using an exemplary embodiment explained in more detail.

Figure 1 shows a section through a rod carpet according to the invention 1 with loops drawn into two poles.

The carpet fabric consists of the binding chain labeled B, which consists of longitudinal threads. The threads of Tie chain connects the weft threads running across the figure with upper shot OS and lower shot US are. The carpet fabric also includes a pile-forming pile chain P, the individual threads according to the invention exclusively from Wool. Together with the threads of the binding chain B and The basic warp G forms the weft threads OS, US the basic fabric of the rod carpet 1 according to the invention.

In Figure 1, 6 rows 3 are shown with Polnoppen 2. In the direction of the longitudinal thread system, the thread density of the rod carpet according to the invention is at least 34 pile threads / 10 cm. The distance A between the weft entries is chosen at the given thread density in such a way that a number of pile nubs of at least 120,000 pile nubs per m ^{2 is} achieved.

The rod entry R is carried out such that a Pole height H of less than 2 mm results.
