Definitions

  • Such a problem of possibility of deformability of the reinforcement is also found in the context of the use of complex structures, constituted by a combination of a nonwoven mat and bidirectional or unidirectional woven structures, which are used in particular for the repair of pipes.
  • a technique which consists in covering the internal surface of the structure to be renovated with a tabular structure made from a complex material flexible, comprising a fluid-impermeable membrane and a fibrous base structure which is impregnated with a non-polymerized synthetic resin and, after plating said complex against the surface of the work to be repaired, causing the resin to polymerize so as to form an internal "sleeving".
  • the sheath After installation over the entire length of the pipe, the sheath is pressurized, so that it comes to press against the internal surface. The resin is then polymerized.
  • the polymerization can also be carried out continuously, for example by light radiation.
  • tubular structure can also present possibilities of deformation under the action of stresses exerted in the transverse direction in order to allow the sheath to press perfectly against the surface of the wall to be renovated when the structure is put under pressure, so that it perfectly matches the surface of the structure to be renovated.
  • the problem may arise of having a possibility of deformation both in the long direction and in the transverse direction while preserving, in the final product ( laminated article, molded article, waterproofing sheet, complex for repairing pipes), high mechanical characteristics in all directions.
  • the invention also relates to a method and an installation for the production of such a type of fabric as well as the use of the latter to produce complexes such as waterproofing coatings, structures for repairing pipes.
  • the material according to the invention consists of a warp and weft fabric made from twist-free wicks of continuous filaments for technical use (glass, carbon, aramid, etc.), wicks which, in the following of the description, will be designated by the generic term "son".
  • a fabric is characterized in that: - the fabric is produced in a plain weave or derived from plain, the density in warp and weft preferably being balanced; - The warp or weft threads are weakened or cut individually at predetermined intervals without significant deterioration in the characteristics of the weft or warp threads located below the weakening or cutting zone;
  • the weakening or cutting zones of a series of threads of the fabric are produced with a lateral and vertical detachment between two consecutive threads or groups of threads.
  • two wires or groups of consecutive wires M is meant that the embrittlement or cutting carried out is actually between two wires with offset of a neighboring wire, or possibly by groups of wires, for example simultaneously on the wire neighbor, this shift being made between two consecutive groups.
  • the strands of filaments constituting the warp and weft yarns are in the form of flattened ribbons, of great width compared to the thickness, width advantageously between 3 mm and
  • the warp and weft are based on wicks of continuous filaments for technical use, such as in particular glass rovings, the overall titer of which is advantageously between 200 tex and 9600 tex, each consisting of 1 to 8 rovings, having a unit titer between 200 to 4800 tex.
  • These rovings are untwisted and the weight of the fabric is generally between 300 g / m 2 and 3000 g / m 2 .
  • the basic fabric is, as indicated above, a fabric produced in a plain weave or derived from plain.
  • the plain armor such as Gros de Tours, fluted, Gros de Naples, plaited or similar, makes it possible to easily vary the width of the strips of thread in the warp or weft direction.
  • the weakened areas which will be produced either on the warp threads or the weft threads, are located on one of the faces of the fabric over the entire width of the locks, the interval between two weakening areas on a thread given is between 10 and 15 cm. These areas are offset from one wire to the wire adjacent to it. Thanks to such a design, a structure is obtained which, despite the embrittlement, or even the cutting of a series of its constituents (warp or weft threads), remains homogeneous and easy to handle and allows it to be used as such. what.
  • such a fabric is, prior to the production of the weakened or cut areas, associated with a fibrous sheet based on staple fibers such as a glass mat, the connection of the two components being obtained by sewing , knitting, the columns of stitches extending parallel between the warp threads, preferably on either side of each thread although this is not imperative.
  • connection could be obtained by not carrying out a straight seam, but a real knitting of the type with thrown stitches, the columns of stitches extending on the face of the fabric whose constituents (warp or weft) must be weakened or cut , and the connecting flanges on the reverse side of the complex formed by the fibrous mat.
  • the invention also relates to a method and an installation allowing the production of such a fabric or complex.
  • this fabric possibly with a fibrous mat
  • a total or partial cutting of the warp or weft threads is carried out, at regular intervals, on one of the faces of the fabric, without total deterioration of the weft or warp thread, located at the level of the embrittlement zone below the cut thread, this cutting being carried out with a lateral and vertical detachment between two consecutive threads with a lateral and vertical detachment between two consecutive threads or groups of juxtaposed threads working in the same way in the weave of the fabric and this, so that two consecutive yarns (or groups) can slide relative to each other when the material is used.
  • Such a method can be implemented on an installation which also forms part of the invention, an installation which is characterized in that it comprises, arranged between a supply station and a reception station, an assembly making it possible to carry out the cutting the warp or weft threads of the fabric, at regular intervals and offset from one thread to the next thread (or group of threads), said assembly comprising: - two cylinders driven in synchronism with the movement of the fabric;
  • these blades When it is desired to cut the warp threads, these blades will be arranged transversely, while in the case where it is desired to cut the weft threads, they will be arranged circumferentially.
  • Such an installation makes it possible to control the precision of the action of the knives so that the cutting is carried out only on the warp (or weft) thread of the visible fabric without deterioration of the weft or the warp thread situated below it. this.
  • FIG. 1 illustrates, schematically, the structure of a fabric according to the invention before making fragile or cut areas
  • Figure 1 schematically illustrates, in perspective, the basic structure of the fabric used in the production of a material according to the invention.
  • Figure 2 is, for its part, the graphic representation of such a fabric.
  • each square represents the crossing points between the warp threads (C) and the weft threads (T).
  • warp threads When the warp threads pass over a weft thread, they are identified by the sign (+) and, when they pass below a weft thread, they are identified by the sign (0).
  • Such a fabric is produced in a plain weave or derived from plain, the density in warp (C) and in weft (T) being balanced.
  • these warp or weft threads are weakened or cut individually at predetermined intervals.
  • the weakening zones are represented in FIG. 2 by the black zones, and are produced with a lateral and vertical detachment between two consecutive wires.
  • a fabric can be used such that, according to a preferred embodiment, it can be associated with a fibrous web based on staple fibers, such as glass mat, the connection of the components being obtained by sewing / knitting, said seams extending parallel between the warp threads, preferably on either side of each thread (C).

  • the upper cylinder has a series of blades (7) located on its surface, the width of which corresponds substantially to the width of the cut wires, said blades (7) being offset with respect to each other both laterally and circumferentially, so as to reproduce fabric structure.
  • these blades When it is desired to cut the warp threads (C), these blades are arranged transversely as illustrated in FIG. 4, while in the event that one wishes to cut the weft threads, they would be arranged circumferentially.
  • This fabric is made from wicks of glass threads having a global titer, both in warp and in weft, of 2400 tex each consisting of 2 elementary rovings of 1200 tex.
  • the weaving is carried out so that the warp threads (C) and the weft threads (T) appear, after the fabric has been produced, in the form of flattened ribbons having a width of 9 mm and a thickness of 0.5 mm.
