Abstract

For the purpose of manufacturing carpets comprising a top layer at the top and at least one backing layer at the back thereof, the top layer (11) on the one side and the backing layer (14) on the other side are simultaneously pressed together with an extruded plastic (10) flowing down therebetween, said plastic flowing down being solidified together in such a way that the top layer is fixed thereby to said backing layer.

Description

METHOD FOR MANUFACTURING CARPETS
The invention relates to the manufacture of carpets consisting mainly of plastic.
Plastic has indeed been used previously for manufacturing carpets. The manufacture of tufted carpets, for example, is carried out by needling a polypropylene yarn into a base fabric each time along the back thereof, so that small loops are formed on the other side of the base fabric. Then the small loops are either cut or retained as loops. On the back of the base fabric a latex layer is then applied which secures the yarn along the back of the fabric and prevents it from coming loose. To said latex layer a backing layer is then applied which consists of latex foam or jute-like fabric depending on the intended use of the carpet.
Woven carpet is manufactured by pulling a poly¬ propylene yarn through between warp threads and weft threads. In known woven carpets, the warp thread consists of cotton and the weft thread normally of jute. A backing layer is applied on the back.
In the case of needlefelt carpets, a needlefelt is made of plastic and on the back a backing layer is then applied which normally consists of latex foam.
A drawback of such known carpets is that the manufacture thereof requires a so-called two-way system, in which the base fabric and the backing layer are moved separately.
Even in known carpets, at least two different base materials are used. This has the drawback that such carpets cannot be recycled completely, because in this case an impure plastic is obtained, which results in environmental pollution.
However, there are thermoformed carpets which largely consist of polyethylene. Such carpets are used in the car industry. The products added when manufacturing such carpets have the inevitable result, however, that recycling produces an impure plastic which is not readily reusable. One object of the present invention is to present a novel carpet development, in particular a novel method for manufacturing plastic carpets.
In order to achieve the above entioned object, the present invention provides a method for manufacturing a carpet comprising a top layer (pile, fabric or needle¬ felt) at the top and a backing layer at the back thereof, the top layer on the one side and said backing layer on the other side being simultaneously pressed together with an extruded plastic flowing down therebetween, said plastic flowing down being solidified together in such a way that the top layer is fixed thereby to said backing layer.
For example, the pressing together of said layers is effected by making them converge between two cooled rollers positioned parallel and next to one another. The spacing between the rollers is controlled in accordance with the total thickness of the carpet.
This method has the advantage that it provides for an economical manufacturing process which, moreover, is genuinely environmentally compatible, because the production process does not give rise to waste waters or the generation of smoke. As a result a carpet is ob¬ tained, comprising a top layer and a backing layer at the back thereof, the top layer being fixed to the backing layer by a solidified plastic layer.
The method according to the invention is suitable for manufacturing, primarily, tufted carpets, woven carpets and needlefelt carpets. It should be emphasised that, as a further advantage of said carpets made in the abovementioned manner, these are completely waterproof.
In particular, it is also an object of the invention to present plastic carpets which can be recycled completely. This object is achieved by using one and the same base material for the yarn, the backing layer, the possible base fabric and for the plastic flowing down. When recycling the carpet, a virtually 100% pure granular material is then obtained which, for example, can be reused for manufacturing the backing layer of new carpets, which has both economical advan¬ tages and advantages with regard to reduced environmental pollution. However, the granular material obtained may, for example, also be employed in the plastics industry for applications in injection and extrusion.
The invention will now be explained in more detail with reference to the accompanying drawings.
In Figure 1, reference number 11 indicates a top layer which may form the top side of a carpet, whether a tufted fabric, a woven fabric or a needlefelt. The back 12 of the layer 11 is turned upwards, and the top 13 thereof is turned downwards. The layer 11 consists of any plastic or natural product or a mixture of a plurality of these. Said layer 11 is moved as a whole between two rollers 15 and 16, respectively, which are positioned parallel and next to one another. Said rollers are water cooled and the spacing between them can be regulated. There is likewise arranged between the rollers a backing layer 14, either felt or web or fabric, or some other, which consists of any plastic or natural product.
Between the top layer 11 and the backing layer 14, a molten plastic 10 is made to flow down by means of an extruder 17. The extruder 17 is fed with a plastic granules or plastic powder. Thus the layers 11, 14 and the molten plastic 10 are pressed together, the backing layer 14 being directly bonded to the pile yarn and said pile yarn being fixed perfectly. The spacing between the rollers is regulated in order to exert a pressure on the running layers therebetween in accordance with the total thickness of the carpet. Cooling of the rollers is adjusted to the speed of the layers therebetween. Thus a robust, finished carpet 20 is obtained in one step.
It should be noted that the manufacturing process is considerably simplified with respect to the conven¬ tional coating procedures and is thus economical. Moreover, the process according to the invention is genuinely environmentally compatible, as it does not give rise to wastewater or the generation of smoke. Preferably, only those plastics are employed which can be recycled in the form of granules.
To summarise, the invention relates to the coating or laminating together of any top layer, either pile or woven fabric or needlefelt, with a backing layer, either felt or web or fabric or another, made of any plastic or natural product, by means of any extruded plastic.
For the top layer, one or more of the following base materials can be used, for example: inter alia polypropylene, polyethylene, polyester, polyamide, polyacrylic, wool.
Regarding the backing layer, one or more of the following base materials can be used, for example: inter alia polypropylene, polyethylene, polyester, polyamide, polyacrylic, jute, cotton.
As far as the extruded plastic is concerned, one or more among the following plastics may be used: inter alia, polypropylene, polyethylene, polyester, polyamide, polyacrylic. All the plastics can also be used with the addition of CaC03.
By means of the invention, a carpet is obtained which comprises a top layer at the top and a backing layer at the back thereof, the top layer being fixed to the backing layer by a solidified plastic interlayer.
Figure 2, for example, represents a tufted carpet in which the top layer comprises a base cloth 11a and a pile yarn lib needled thereinto. The top layer, i.e. the pile yarn together with the base cloth, is fixed to the backing layer 14 by the solidified plastic interlayer 10.
In the case of tufted or needlefelt carpets, in which said backing layer consists of a plastic felt, the method can be used in such a way that a second extruded plastic is made to flow down at .the rear side of the plastic felt in such a way that a plastic fabric can be bonded thereto. Figure 3 shows a carpet comprising a second solidified plastic interlayer 18 with a plastic fabric 19 thereon.
It is furthermore possible, by employing one and the same base material for the top layer, the backing layer and the extruded plastic, to manufacture plastic carpets which can be recycled completely, a virtually 100% pure granular material being obtained in the process. Moreover, it is possible to use, for the interlayer to be extruded, a recycled granular material or powder, resulting in a reduction in cost of manufacturing.
