Definitions

  • the present invention relates to a method of manufacturing a textile coating, as well as such a textile coating, which can in particular be a floor covering, a wall covering or a covering carpet of the passenger compartment of a vehicle.
  • the back of the velveteen is impregnated with an aqueous solution of latex. Then, the assembly is subjected to a drying which has the function of removing the water from this solution until the latex reticles, but which has the drawbacks of requiring important equipment and being expensive.
  • the latex After drying, the latex forms bridges which bind the fibers of the web together, in the area below the loops.
  • the latex is non-thermoplastic and its presence in the textile coating impairs the recycling of the latter.
  • a textile coating by coating the underside of a fiber web with a coating which can be deposited in molten form to then solidify by cooling.
  • This coating can also come from a powder or a hot melt film which is melted only after its deposit on the underside of the sheet.
  • the coating on the underside of the web does not provide satisfactory mechanical properties, especially in terms of dimensional stability and abrasion resistance of the textile coating.
  • the invention aims at least to simplify the manufacture of a textile coating, without this is accompanied by a degradation of some of the mechanical properties of the textile coating.
  • the alternating electric field concentrates the powdered binder in the cohesion zone. Indeed, it would have been expected that the alternating electric field disperses the binder powder over the entire thickness of the textile coating, to the extent that it is known, for example document WO 99/22920 , one Similar alternating electric field could effectively be used to effect homogeneous impregnation of a fibrous layer with powder.
  • the upper part of the coating that is to say the second region, is as free of binder as possible.
  • the previously defined process does not use dissolution and no drying is required. It can be implemented by means of a significantly less significant installation and less expensive than a facility handling a latex solution.
  • the method defined above has the further advantage of offering flexibility as to the amount of binder in the textile coating and the location of this binder.
  • This location can be modified by changing the face where the binder is deposited in powder and / or by varying the proportion of this powder binder deposited on one of the face of the web, relative to the amount of binder in powder deposited on the other side of the sheet.
  • the location of the binder inside the web also depends on the residence time of the web between the electrodes, setting parameters of the field created by these electrodes, the peculiarities of the powder and in particular its particle size, as well as the fibers of the web and the density of this web.
  • the hot melt binder is more specifically a thermoplastic binder. It can also be otherwise.
  • the hot melt binder may be a fusible binder at a first temperature and thermosetting at a second temperature above this first temperature.
  • the hot melt binder may be a polyethylene, a polypropylene, a polyester, an epoxy resin or a mixture thereof.
  • the fibers of the web are advantageously made of a polymer, such as polypropylene, polyester, polyamide or a mixture thereof. It may also be cellulosic fibers. The web may also comprise different kinds of mixed fibers.
  • the powder binder is a mixture of powders of different chemical natures.
  • the method comprises a step in which the back side is coated with a coating containing fillers.
  • the invention also relates to a textile covering comprising a web which is made of fibers and which comprises a reverse side, a first region, a second region and a locus face, the first region being a cohesion zone where the fibers of the ply fit into a tight entanglement holding these fibers and which is located on only a portion of the thickness of the ply, the second region extending over another portion of the thickness of the ply, above said ply first region, up to said face-face, a hot-melt binder joining fibers of the web between them and concentrating in the first region which comprises a core and a surface area connecting this core to the reverse side of the web, the proportion of binder hot melt with respect to the fibers being lower in the superficial zone than in the heart.
  • an undercoat such as a coating may cover the underside of the web. It is easier to adhere to the back of the tablecloth if this back is poor in binding. In the absence of an underlayer, the underside of the web also forms the underside of the coating.
  • the hot melt binder is advantageous in that it can be melted again by further heating the textile coating, after which this coating can be compression formed between two forms.
  • the textile coating results from the implementation of a method as defined above.
  • FIG. 1 On the figure 1 is represented a plant 1 for manufacturing textile coatings or carpet 2 from a velorized needled web 3, using a method according to the invention.
  • the web 3 is initially dry, that is to say not impregnated. It is composed of polymer fibers 4 which interlock and thus form a tight entanglement 5 located on only a part of the thickness 6 of the web 3.
  • the entanglement 5 holds the fibers 4 and is located in another part 7 of this thickness 6.
  • the fibers 4 are generally independent of each other at this other part 7, where they form loops 9 and which extends to one of the two main faces 8A and 8B of the web 3, namely its face 8A intended to form the top or location of the belt 2, the face 8B being intended to form the bottom or back.
  • the web 3 has loops 9 on the side of its face 8A, since it is a needled velvet ply.
  • the web 3 may have a simple needling, that is to say, not be velvety.
  • a roll 10 of web 3 is unwound towards an impregnation device 11, in the direction symbolized by the arrow F at the figure 1 .
  • an impregnation device 11 Upstream of this impregnation device 11, a substance consisting essentially of a hot-melt binder 12 in powder form and which may also contain one or more additives, in particular fluidifying additives, is sprinkled on one of the main faces 8A and 8B of the sheet 3 .
  • This binder 12 is made of a thermofusible material whose melting temperature is lower than that of the fibers 4. Its flow rate is determined by a sprinkling device 13 synchronized with the speed of advance of the web 3 in the direction F.
  • the impregnation device 11 comprises two facing electrodes 14 and 15 that are generally plane and parallel to one another, between which the layer 3 carrying the binder 12 in powder passes. These electrodes 14 and 15 generate between them an alternating electric field to which the ply 3 and the binder powder 12 are subjected at the same time. This field makes penetrate the binder 12 in powder in the thickness of the sheet 3, including in its entanglement 5. It was also found that, surprisingly, the alternating electric field produced between the electrodes 14 and 15 concentrates the binder 12 powder at this tangle 5 so that, at the portion 7 of the web 3, the fibers 4 contain practically no powder binder 12, which is desired.
  • the electrodes are flat and parallel to each other. However, in some cases, it may be advantageous to use electrodes having another shape and / or not parallel to each other. These electrodes may especially be those described in the document WO 2005/038123 .
  • an aspirator 16 subjects the face 8A to suction, that is to say to a cleaning intended to remove any binder grains 12 found in the part 7 of the sheet 3. This suction can be removed by being replaced or not by brushing.
  • the structure of the sheet 3 directly after the vacuum cleaner 16 is visible at the figure 3 , where it can be seen that the binder 12 in powder concentrates essentially at the level of entanglement 5.
  • a hot air oven 17 Downstream of the vacuum cleaner 16 is a hot air oven 17, in which a supply of heat melts the binder 12. Following this, the sheet 3 passes between two pressure rollers 20.
  • the sheet 3 is subjected to a jet of cooling air 21 that one or more nozzles 22 expel and which causes the solidification of the binder 12. Also, the rollers 20 can be cooled and participate in the solidification of the binder 12. They can even cause this solidification without the presence of the cooling jet 21. It is also possible to allow the cooling of the binder 12 alone.
  • the web 3 After solidification of the binder 12, the web 3 forms a textile coating, which is cut into several mats 2 by a knife 23 in the example shown.
  • Binder bridges 12 unite the fibers 4 to each other at the level of the entanglement 5 and, in doing so, secure the loops 9 to the remainder of the carpet 2.
  • the proportion by weight of binder 12 with respect to the fibers 4 varies in the direction of the thickness, at the level of the entanglement 5. specifically, this proportion is greater at a center 25 of the entanglement 5 than at a surface region 26 bordering this core 25 opposite to the portion 7 and defines the lower face 8B of the carpet 2.
  • the small proportion of binder 12 in the superficial zone 26 is visually observed on the lower face 8B. It can also be verified by measurements. These measurements can be based on a comparison by thermal analysis of the enthalpy of fusion of the fibers 4 alone and the enthalpy of fusion of the sample to be evaluated, for a fusion only of the fibers 4 present in this sample, to the Excluding its binder 12. From this comparison, we deduce the proportion by mass of fibers 4 in the sample and therefore that of binder 12.
  • the sample is prepared by sanding performed so as to leave only what must be measured and remove the rest. For example, the sample prepared to measure the amount of binder 12 in the surface area 26 results from sanding removal of the portion 7 and the core 25.
  • a hot melt binder 12 compatible with the carpet fibers can be selected so that the carpet 2 can be recycled.
  • the sheet 3 is a needled velor product having a basis weight of 600g / m 2 and a thickness of about 6mm. It consists of a mixture of fibers 4 of 6.5 dtex, 17 dtex and 150 dtex, made of polypropylene and initially devoid of any binder.

  • the sheet 3 provided with the binder 12 in powder form is subjected for 20 s to the alternating electric field. It then stays longer than 2 minutes in the oven 17 set at a temperature above the melting temperature of the binder and below the melting temperature of the fibers.
  • a carpet 2 obtained according to this example 1 was subjected to the Lisson test as defined by the EN 1963 standard of the year 1997. After this test, a determination by visual evaluation of the level of defibration of the carpet 2 was carried out and gave a value of 3/5 in the machine direction, that is to say in the direction of arrow F to figure 1 and a value of 3/5 in the transverse direction, that is to say in the direction perpendicular to the machine direction.
  • the carpet 2 had an average thickness of 6 mm.
  • the proportion of binder 12 throughout its thickness was evaluated at 29.5% by weight by the method mentioned above and involving measurements of fusion enthalpy.
  • the proportion of binder 12 in the last millimeter before the face 8B, that is to say on the back of the belt 2, globally at its surface area 26, was evaluated at 16.9% by mass by the same method. It can be deduced that the proportion of binder 12 in the surface zone 26 is less than that in the core 25. This is to compare the same measurements made on a second carpet, made from the same web but by implementing the method of the prior art, that is to say using a latex solution.
