Definitions

  • the present invention relates to the general technical field of textile grids formed of a network of warp and weft threads held in place by bonding at the crossover point of the threads, such grids acting in particular as reinforcements or supports in different industrial applications .
  • the present application discloses a textile grid formed by a network of crossed or superimposed nonwoven threads comprising at least two plies of warp threads between which is interposed at least one ply of weft threads, the warp and weft threads being linked between them at their crossing by a binder creating a series of bonding points.
  • the present application also discloses any finished or unfinished industrial product incorporating such a textile grid.
  • the present invention relates to a process for manufacturing a textile grid in which a network of crossed or superimposed nonwoven yarns is produced comprising at least two plies of warp yarns between which is interposed at least one ply of weft yarns, and coated the network of wires with a binder to ensure the connection of the weft and warp threads with each other.
  • the grids produced according to this technique generally give satisfaction and serve as reinforcements or supports in very varied technical fields such as for example without limitation, in the building industry, as a support for parquet floors and ceramics or wall coverings and carpets, in the paper industry, or even as a reinforcement element in synthetic or other foams.
  • the textile grids known to date suffer from a certain number of drawbacks and in particular a drawback linked to the relatively large and mainly very irregular thickness of the grid.
  • the method of manufacturing known grids involves a simple coating of an adhesive or thermoplastic binder, of the PVC or PVA type for example, without any other additional operation.
  • the textile grids obtained have a relatively large thickness whatever the nature, type, number of threads used, leading to a relative lack of flexibility of the grid obtained.
  • the thickness of the textile grids known to date is particularly irregular due to the existence of a relief at the crossing points of the warp 1 and weft 2 threads. The presence of such irregularities at the Textile grids of the prior art obviously have a certain number of drawbacks on the industrial level, and particularly in certain specific applications.
  • the textile grids of the prior art appear to involve a relatively large consumption of the adhesive or thermoplastic binder used, particularly if one wishes to try to reinforce the mechanical strength of the network of wires at the crossing points. . This leads to an increase in the cost price of the products obtained, which constitutes an industrial disadvantage.
  • the technique of compression by calendering of the textile grid is not accompanied by a reduction in the amount of adhesive used.
  • the calendered textile grids in addition to the relative complexity and difficulty of obtaining the product on the industrial level, suffer from a certain number of drawbacks making their use limited or even inappropriate in certain applications.
  • the invention aims to propose a new method for manufacturing a textile grid formed by a network of crossed or superimposed nonwoven yarns which is particularly simple to carry out.
  • the textile grid produced according to the method of the invention is formed by a network of crossed or superimposed nonwoven threads comprising at least two plies A, B, of warp threads 1 between which is interposed at least one ply C of threads of frame 2.
  • the construction of the network of warp threads 1 and weft threads 2 is obtained by shifting the warp and weft threads without overlapping, or on the contrary by ensuring a overlapping of the wires.
  • the network of warp 1 and weft 2 threads can be obtained with a crossover of the warp and weft threads at 90 ° (square construction) or according to a different angular inclination, for example tri-directional.
  • the textile grid may be formed by a number of variable threads, which can, for warp threads, vary from 0.5 thread per centimeter to 8 threads per centimeter, and for weft threads, which can vary, for example, from 0 , 5 threads per centimeter to 5 threads per centimeter.
  • any type of textile thread commonly used to date in the production of textile grids may be used, and for example threads of the Silionne, polyester type, cellulosic, aramids or polyamides.
  • the warp 1 and weft 2 threads are linked together at their crossing 3 by a binder 4 creating a series of bonding points at the intersection of the network of threads.
  • any binder or adhesive commonly used to date in the technical field considered may be used, and in particular any binder or thermoplastic adhesive.
  • the connection and coating of the network of threads forming the textile grid according to the invention may be formed by synthetic latexes (SBR, etc.), PVAC, plastisols, PVC, polyvinyl alcohol (PVA), conventional iron-on impregnations, polyurethane binders or acrylic binders for example.
  • a textile grid which has a reduced thickness, and for example preferably less than 0.175 mm and regular without the existence of a significant relief at the crossing of the warp 1 and weft 2 son, while having a excellent mechanical strength of the wire network with a glue consumption lower by at least 30% at least compared to conventional textile grids.
  • the thickness of the grid is substantially equal to twice the thickness of the single wire excluding the crossover.
  • the textile grid obtained has good flexibility as well as a reduced bulk since, in comparison with the known conventional textile grids, the footage wound on the same spool can be multiplied by two in the case of a textile grid conforming to the invention.
  • a grid is disclosed, the thickness E of which is preferably less than 0.150 mm and even more preferably between 0.150 and 0.06 mm.
  • T is obtained by averaging the titles of the warp and weft threads used: Headline chain + title weft 2
  • Table 1 expresses in a comparative manner the measured values, characteristic of a fine grid in accordance with the invention and of a normal grid of the prior art, for the same composition of a network of wires for the same thermoplastic binder, for six different compositions of the wire networks.
  • table 1 state grids produced from identical warp and weft threads and also of identical title, it being understood that, within the meaning of the invention, the networks of warp threads and weft of the same grid can be made with threads of different nature and of different title without departing from the scope of the invention.
  • the performance rate of the textile grid according to the invention is then calculated by taking the statistical average of the titles of the warp and weft threads.
  • grids of the prior art produced with warp and weft yarns composed of 68 tex glass yarns with an EVA (ethylvinylacetate) thermoplastic binder (adhesive content 20 to 30%) exhibited mechanical resistance to breakage. less than 0.55N, while the breaking strength of grids of the same composition produced according to the process of the invention, with an adhesive content reduced to about 12 to 15% was close to 0.95N.
  • EVA ethylvinylacetate
  • the application discloses the use of glass yarns whose title of warp and weft yarns is between 5.5 gr / km and 136 gr / km.
  • the measurement method used to calculate the area of the bonding point expressed in square millimeters was carried out by measuring the overlap area of warp thread 1 on the weft thread and taking the average value from ten measurement points. .
  • the method used for determining the linear mass or the titer of the wire complies with standard NF G07-317 (ISO 2060 of 06/95) for wires other than glass and carbon.
  • the method for determining the linear mass, expressed in gr / km was carried out according to standard T25-020 (ISO 1889 of 08/97).
  • the thickness of the grid was measured in accordance with standard NF G37-102.
  • Rate of glue 1 - the mass of son sure a metre square the mass of the wire rack in g sure a metre square
  • the method of manufacturing a textile grid according to the invention and as described above implements a series of conventional production steps well known to those skilled in the art using conventional parameters of manufacturing adapted to the nature and title of the weft and warp threads used, and to the nature and the rate of glue used.
  • the manufacturing process implements a general stage of construction of the network of wires, followed by a stage of impregnation and determination of the appropriate rate of glue, then by a stage of drying of the grid obtained.
  • These devices essentially comprise a rotating element, commonly called a fin, which distributes one or more weft threads around two support elements for rotating threads, spaced from one another so as to form between these elements a series of spaced loops which form a web of wefts.
  • the shaft supporting the fin is hollow and at least one of the weft threads is brought to the fin by passage inside said shaft.
  • the rotation of the support elements moves the weft ply laterally, the wire loops forming this ply remaining parallel to each other. This ply of moving wefts is then assembled by gluing with one or more plies of warp threads which are brought into adjacent coplanar relationship with it by means of appropriate guides.
  • the peculiarity of the manufacturing process according to the invention resides in the fact of ensuring the pressing of the network of warp and weft threads before the drying phase of the binder is completed, the glue still being in a substantially or completely liquid or fluid state.
  • the pressing of the network of wires is carried out at least in part simultaneously with the drying phase of the binder.
  • the manufacturing process can be carried out industrially continuously using conventional elements involving reels, pressing elements and drying elements including a series of cylinders.
  • the textile grid produced in accordance with the process of the invention can be used as such in the various conventional applications as mentioned above, namely as reinforcing or stabilizing elements. In addition, it can also be used and incorporated into another element to form an industrial product incorporating it.
  • the structural characteristics to be taken into account for the realization of the grid will be identical to those of the simple grids, the thickness E of the complex grid being that of the grid itself, equal to the thickness of that of the complex minus that of the nonwoven element.
