Definitions

  • the present invention relates to a textile complex for producing thermal protective clothing.
  • the complex is aimed at providing thermal protection against heat and flame, being used for the realization of clothing for firefighters but also, more generally, in other areas of activity where there is a risk of burns due to heat or fire.
  • a jacket must have a number of criteria, including protection against radiant heat, protection against convective heat, have a good thermal stability of the constituent materials, meet criteria of pure fireproofness, and have good impermeability.
  • a textile complex for producing such equipment is known from US-A-5,274,849, which represents the preamble of claim 1.
  • a jacket must allow an operator to protect it in extreme conditions of an accidental nature, including by providing a time of escape.
  • it is necessary to protect a firefighter against a phenomenon of "flash-over". Flash-over is a very fast transition stage in the development of a city fire and occurs when gases and vapors in a room reach a temperature of 500 to 600 ° C and ignite suddenly. In a fraction of a second, the temperature rises from 500 to 1000 ° C, corresponding to an incident heat flux of the order of 40 kW / m 2 .
  • An operator should be allowed to resist this sudden increase in temperature long enough to be able to move away from home.
  • Such a textile complex comprises an outer protective fabric made of a non-flammable material, for example based on aramid fiber, meta-aramid or polyamide imide.
  • This fabric incorporates thermal protection qualities, provides mechanical resistance to abrasion and tear, and has been water-repellent to water-repellent and chemical-liquid-repellent in general.
  • Behind this protective fabric is a waterproof and breathable membrane, generally fixed on a textile surface ensuring its mechanical strength, allowing to let the water vapor resulting for example from the perspiration of a user, but not the water under its liquid form.
  • this membrane provides a windproof effect, which contributes to the thermal insulation of the jacket by slowing the penetration of heat flows.
  • thermal insulation consisting of a three-dimensional mesh knit, as described in document EP 0443991, or by a felt capable of trapping air, as described in document EP 0 364 370.
  • This thermal insulation is usually sewn on a liner.
  • Such a jacket has the advantage of providing excellent thermal protection under an extremely high heat flow of 40 kW / m 2 , a very important efficiency, even too important because of its high insulating power it does not allow to the user to be sensitive to heat to heat flows of 0 to 1 kW / m 2, corresponding to the usual working conditions of firefighters, and to detect a possible danger. Under these conditions, the overprotected operator may have to take unmeasured risks due to an alteration of the perception of the heat flow.
  • Such a jacket is also uncomfortable insofar as it is thick and heavy, and where it is loaded with water, especially at the level of the thermal insulating material, which can be translated, in case of sudden rise in temperature, by a vaporization of this water likely to burn the operator.
  • the felt or knit mesh absorbs a lot of water, resulting in a significant drying time during which the jacket is wet. is not usable.
  • Figures 1 and 2 show two graphs that illustrate the behavior of different complex designed to make clothing for firefighters, taking into account the European standard EN 469.
  • FIG. 1 illustrates the evolution of the heat transfer factor TF%, which is the ratio of the heat flux that has passed through the product to the incident heat flux Q o .
  • the incident heat flux is the heat flux generated by a thermal source to which the sample is exposed.
  • FIG. 2 illustrates the evolution of the warning time T. 12 as a function of the incident heat flux Q o .
  • the warning time is the time after which the user painfully feels the heat. It is sought to obtain a T. 12 of about 15 seconds for an incident flux of 40 kW / m 2 .
  • the object of the invention is to provide a textile complex for clothing production, which is light and comfortable, which, under usual conditions of intervention (flow of 0 to 1 kW / m 2 approximately), transmits the heat relatively well (which corresponds to a high TF%) and quickly alerts the operator of the presence of a hazard (which corresponds to a low T. 12 ), and which, in critical conditions, such as a resulting heat flow a flash-over phenomenon (flow of the order of 40 kW / m 2 ), ensures for a sufficient period of time and in compliance with the standards, a high insulation rate (ie a low TF%), to ensure the operator a reasonable time of escape.
  • this complex must allow rapid drying when wet.
  • the textile complex it concerns of the type comprising at least one fabric or a textile web, made of a non-flammable material, intended to form the outer face of the complex and a comfort and cleanliness lining intended to form the inner face of the complex, is characterized in that on the inner face of the fabric and / or on the outer face of the lining are disposed beads of textile material having substantially the same orientation, fixed by bonding to the fabric and / or on the lining during its manufacture, to be an integral part, and delimiting between the fabric and the lining of the channels filled with air.
  • the beads delimit with the lining, on the one hand, and the wall of the complex vis-à-vis the lining, on the other hand, channels that are filled with air.
  • This air is not static but can circulate, insofar as it is not trapped, by a tight mesh, as is the case for example with structures of knit type three-dimensional mesh or net.
  • the amount of air in the channels defined by the beads constitutes a sufficient thermal insulation, and meets the standard EN 469, to allow the operator to move away from the dangerous place.
  • the beads are made of a material that is not very compressible under the effect of an increase in heat.
  • each bead is made from thermostable fibers, such as para-aramid.
  • each bead is constituted by a bundle of son assembled to each other, for example two Nm 8/2 twists twisted together.
  • Such a structure is less compressible than an equivalent title wire composed of a single end.
  • each bead is attached to the liner by bonding with the son of this liner, during the manufacture thereof.
  • the thickness of each bead is greater than 0.3 mm, and preferably between 1 and 10 mm, and the spacing of the beads is greater at 2 mm, and preferably between 2 and 15 mm.
  • the beads and the channels they delimit have a longitudinal general orientation to the garment, and especially vertical in the case of a jacket, promoting air circulation by a natural phenomenon of convection.
  • the complex represented in the drawing comprises an outer protective fabric 2 made of a non-flammable material, consisting of a fabric reference 4781 from DMC Tissus Techniques, Twill 2/1, 195 g / m 2 , in Nomex® Delta TA from Dupont de Nemours, blend of 75% meta aramid fibers, 23% aramid fibers and 2% antistatic fibers.
  • a waterproof and breathable membrane consisting of the reference 89/55 of the company Proline, waterproof and breathable microporous membrane in flame retardant polyurethane of about 40 g / m 2 , laminated on a nonwoven Sontara ⁇ Nomex ⁇ SL Type E-89, mixture of meta and para aramid of about 90 g / m 2 .
  • the complex finally comprises a liner 4 consisting for example of a fabric reference 4948 from DMC Tissus Techniques, Canvas 120 g / m 2 , made of Nomex® / Viscose FR, a blend of 50% of meta-aramid fibers and 50% of fibers. viscose flame retardant in the mass.
  • a liner 4 consisting for example of a fabric reference 4948 from DMC Tissus Techniques, Canvas 120 g / m 2 , made of Nomex® / Viscose FR, a blend of 50% of meta-aramid fibers and 50% of fibers. viscose flame retardant in the mass.
  • a series of continuous parallel beads 5 representing a mass per unit area of 70/80 g / m 2 , in this case consisting of 100% Nm aramid fiber yarn. 8/2/2 (doubling of 2 ends of Nm 8/2).
  • the lining is constituted by a fabric, the connection of the beads with the fabric is obtained during weaving, by a particular evolution of certain background threads of said fabric.
  • the layers 2, 3 and 4 are generally not assembled, but simply juxtaposed. However it is quite possible that some of these layers are assembled by gluing for example, in the case of specific needs.
  • each bead is of the order of 1 mm, and the spacing of the beads is of the order of 10 mm.
  • FIG. 5 represents a jacket 6 made from the textile complex which has just been defined, and in which the beads 5 are oriented vertically.
  • FIGS. 1 and 2 illustrate the behavior of a complex I according to the invention.
  • This complex has the advantage, compared to some existing complexes, to be lighter and more flexible, the beads 5 advantageously replacing a felt for trapping air. These beads are lighter and more flexible than such a felt or knit three-dimensional mesh.
  • the pumping and water storage capacities of the insulating complex of the invention are practically reduced to those of the lining used as support for the beads, which in its embodiment as described above represents 2.5 times its weight. dry. In comparison that of the complex F using a felt, which acts as a sponge, is 10 times its dry weight.
  • the lining serving as a support for the complex of the invention is converted into an exchange surface of the sweat water (which it absorbs) with the air circulating in the formed channels. by these so-called beads, accelerating evaporation and allowing the body to thermoregulate much more quickly.
  • the onset of heat stress is delayed or suppressed, especially under the usual working conditions of 0-1 kW / m 2 .
  • This low water absorption capacity of the complex according to the invention also has the advantage of limiting the risk of burning by vaporization of the water trapped in the jacket in the event of exposure to a sudden heat flow.
  • the volume of air maintained in the channels ensures a satisfactory thermal insulation by limiting a rapid transmission of heat under critical conditions (flow of the order of 40 kW / m 2 ).
  • the structure of this complex also ensures good sensitivity to heat under normal conditions of use, and therefore a low warning time T. 12 , due to its low surface area, as shown in FIG. Warning in normal conditions is similar to that of leather + lining complexes, recognized as being more reassuring than that of traditional textiles too insulating (curves E and F).
  • the complex according to the invention provides a good comfort at low energy, 0 to 1 kW / m 2 (usual working conditions) comparable to that of leather + lining complexes recognized as posing few problems of heat stress, which results in a relatively high TF% (good heat transfer).
  • it has high incident heat fluxes (about 40 kW / m 2 ), a TF% heat transmission factor, low (good insulation), comparable to that of much heavier complexes, less comfortable and retaining much more the water.
  • the invention is not limited to the sole embodiment of this textile complex or its sole application to the realization of a jacket, it encompasses all variants. It is thus in particular that the lining could be associated with a membrane or a film, that the beads could be discontinuous and / or could be made of another material, such as silicone, or that the complex could be constituted by two unbonded layers, such as trousers and overpants on the inner side of which are arranged beads, without departing from the scope of the invention.
