The innovation relates to carpets, rugs and similar woven goods.

Woven carpets are generally made by using the basic chain forming the carpet pattern, Pile warp, pile warp and the like. · With a weft thread, mainly made of flax or hemp, woven. the The quality of a carpet produced in this way is judged by how tight the loops the warp thread is through the weft threads are tied in. This is especially true for

So-called pile carpets the case in which the pile warp is cut open during the weaving process, so that the result resulting individual loops are only held by the weft thread.

The weft threads made from flax, hemp or jute have only a low elasticity in contrast to other weft threads, but the remaining elasticity is sufficient, to bring about a certain loosening of the association between the warp and weft threads, which leads to The consequence is that the cut loops can be removed more easily.

The problem with the innovation is to improve the bond between the warp threads and weft threads significantly und.to avoid the disadvantages described.

According to the innovation, this task is solved by that the weft thread binding the pile or pile warp or the like consists of a thermoplastic material or is provided with a thermoplastically reactive coating, with the help of which during weaving or afterwards a stronger connection of the threads in the loop area can be achieved by heating.

A carpet, runner or the like produced in this way has the advantage that the warp thread loops

are particularly firmly connected to the weft threads, because the mechanical integration that is already present is superimposed an adhesive connection of the threads in the contact area, because the heating of the carpet causes the covering the weft thread is softened and thereby has adhesive properties. The individual loops are thus completely or partially encompassed by the softened coating compound, this connection being fixed when the The carpet is then cooled down again. A single cut loop can then only be underneath Tear destruction of the cover out of the carpet.

In this way, however, other advantages are also achieved, because the application of a coating on the Weft thread means that its elasticity is significantly reduced. A weft thread prepared in this way; extremely low-shrinkage, so that the mechanical durability of the carpet alone is significantly greater than is the case with known procedures. The thermoplastic coating also reduces the friction of the thread elevated. If the weft thread also comes to rest on the underside of the carpet, it wears due to its cover significantly contributes to making the carpet more slip-resistant. Finally, through the coating of the weft thread an isolation brought about / 'that the adhesion of the

Dirt on the weft thread difficult. The one after the innovation produced carpets are thus characterized by a. reduced risk of contamination. After the wefts Mainly made of flax, hemp or jute, which normally over time a certain Are subject to the risk of rotting, this risk is also reduced or reduced by the coating according to the invention; eliminated, because the flax, jute or hemp core of the weft thread is protected from the ingress of air.

Although it is known to have the back of a carpet with different To coat finishing agents. On the one hand, coatings made of latex or rubber are used to to make the carpet non-slip. But it is also already known to cover the back of a carpet with a heat-sealing lacquer to be coated in order to create an adhesive connection between the loops and the remaining threads. This procedure is extremely expensive and cumbersome because a large amount of the heat seal varnish is applied must in order to penetrate the basic chain at all. In any case, a special step is required for this finished carpet required.

In contrast to this, the working hours in the production of the carpets according to the innovation are not affected, because already

a pre-coated weft is used. It lies It is also clear that the amount of the coating processed in the sense of the innovation is significantly less than for the known measures is.

For the sake of innovation it is recommended to use the warp thread to cover with a copolymer and to dry the cover before winding the warp thread. To this This ensures that the coating on the bobbin does not impair the running properties of the warp thread. It also proves to be particularly advantageous if the coating is based on polyvinyl alcohol or polyethylene. These chemical substances have the advantage that they can be used in dry cleaning of a carpet behave relatively neutrally, while coatings based on polyvinyl chloride through the chemical solvent, especially perchlorethylene, are attacked to the extent that the plasticizer is dissolved out. The carpets produced according to the innovation can thus be cleaned using chemical cleaning.

The subject of the innovation is also a woven carpet, runner or the like, in which the pile or pile warp .Or the like. Binding weft thread consists of a thermoplastic material. For this, there are essentially

Some synthetic threads are considered, but it is also possible to use a mixed thread as weft thread, in which a thread component consists of a thermoplastic material. It is essential that the so produced Carpet is subjected to a heat treatment whose terapeirur in the softening range of the thermoplastic Material lies so that the warp thread from the thermoplastic and softened material are grasped and adhesively bonded to the weft thread.

In terms of the innovation, the warp thread can also have a thermoplastic coating, for example on Based on polyethylene, polyvinyl chloride or polyvinyl alcohol, which is obtained when the carpet is finished by heating is softened.

Details of the revision can be found in the drawing. In it the innovation is shown schematically and for example. Show it:

In the embodiments of the Pig. ' 1. To 3 is the Longitudinal section through the binding of a smooth carpet 1, a knobbed or looped carpet 2 and a pile carpet 3 shown. In each case a basic chain 4 and a binding chain 5 is used, the Binding chain 5 is woven with the weft thread 6 and thereby results in the carpet pattern. The firmness of the carpet in particular the loops of the knobbed or looped carpet shown in FIG. 2 depends essentially on the strength the binding through the lock thread 6. If the Weft thread 6 is elastic, a loosening of the binding can take place through elongation phenomena.

In terms of the innovation, the weft thread 6 is provided with a sticky property that only occurs when heated of the carpet or the weft 6 comes into play. This thermoplastic property can be used in the sense of Achieving innovation in various ways. First of all, it is possible to make the weft thread 6 entirely from a thermoplastic Manufacture material, especially synthetic material. By heating and adhesive connection this weft thread 6 with the warp threads, these threads, which are very elastic in themselves, lose a considerable amount of elasticity. In order to reduce the elasticity even further, a thread made of different materials can be used, for example to form the weft thread 6 are produced at

for example the soul made of flax, hemp or jute and the jacket is made of a thermoplastic material. Ultimately, however, the innovation looks too before, the weft thread 6 with a coating 9 (see. FigA) provided, whereby it is also recommended to use hemp, flax or jute as the soul, because these materials are in in carpet weaving have proven themselves very well.

No matter how the thermoplastic material is connected to the weft thread 6, the carpet in the region of the softening point is due to the heat up S \ mung an adhesive connection between the loops 10 and the weft threads 6, which supports the mechanical integration of the warp extremely effective This affects in particular in the pile carpets $ shown in FIG. 3 from where the loops are cut 10 so that each loop is held only by the weft yarn 6 10. In the enlarged view according to FIG. 4- it can be seen that in a connection area 11 of more than 180 ° there is an adhesive connection between the loop 10 and the weft thread 6 when the overcoat 9 is made thermoplastic by heating and then cooled again.

In the example of Fig. * 5 a device is shown, with the help of which it is possible in the simplest possible way to find the

To apply coating 9 to the weft thread 6 as shown in FIG. The weft thread, which in this example consists of hemp, flax or jute, is pulled off a pay-off spool, passed through an applicator 14, where the Weft thread 6 receives its coating in an overdose. With the help of the squeegee rollers 15 or similar stripping elements (z. B. felt strips) the excess amount of weft thread 6 is removed. The remaining coating will completely dried out within the drying channel 16, so that the coated weft thread 6 with the aid of the pair of draw rollers 17 easily wound onto the supply reel I3 can be without the risk of mutual adhesion of the turns.
