Definitions

  • the invention relates to a textile fire barrier. It will find its application in particular in the field of security to form a protective screen and avoid any propagation of the flame. It concerns the clothing industry, furniture, construction, aeronautics and all means of land or sea transport.
  • the material must therefore not give off abundant harmful gases and also, must not propagate the flame.
  • Flame resistance standards can be broken down into two categories depending on the nature of the tests to be performed.
  • the test is essentially thermal. This involves bringing the object to be tested to a temperature close to 450 ° C under the action of a flame for a determined time and verifying that after this action, the hearth is not maintained.
  • the fire barrier must also have elasticity and deformability properties compatible with the seat cushion.
  • the main object of the present invention is the production of a fire-resistant textile barrier which has good mechanical flexibility properties which make it compatible with applications in clothing and furniture and which, moreover, in terms of safety, offer guarantees with regard to the action of a flame.
  • the fire-resistant textile barrier meets the standards imposed both with regard to public places and land vehicles as well as in aeronautics and marine.
  • the textile barrier of the invention protects it and prevents the mouse from spreading the fire.
  • the present invention relates to a fire-resistant textile barrier intended, in the field of security, to form a protective screen and avoid any propagation of the flame. It will find its application in particular in the clothing industry, of the furnishing, in particular for the confection of the seats of vehicles and in aeronautics and the Marine.
  • the present invention has been more particularly developed to equip the seats of vehicles, airplanes and boats. Its use may however be extended to other equipment such as performance halls, clothing or others.
  • the polyurethane foam generally used exhibits very poor behavior in the event of a fire because it melts and burns while maintaining the flame. It is therefore advisable to protect the foam by an enveloping screen which shelters it from the direct action of the flame, preventing it from being consumed. This is precisely the role of the textile fire barrier of the present invention which has the mission of forming a screen on the surface of the foam cushion to prevent it from propagating the flame.
  • the tests planned for rolling stock such as railroad cars, in which the seat is subjected to the action of a simple flame releasing for a predetermined time a temperature between 600 and 1000 ° C. .
  • this test is carried out using one hundred grams of parboiled paper at 140 ° C rolled into a ball. This paper is placed on the seat then lit. After the paper has gone out, for the test to be conclusive, a natural and rapid extinction of the flame on the surface of the seat must be observed.
  • the fire barrier must therefore prevent the flames from communicating with the ground or disintegrating the product.
  • the second type of test relates to aeronautics where a burner supplied with kerosene is used having a nozzle of twenty centimeters of cone and placed at a distance of ten centimeters from the seat. The latter is subjected to the action of the flame brought to 1040 ° C for two minutes.
  • FIG 1 shows a seat (1) having a cutout of the wafer (2) to illustrate the different internal elements.
  • This seat has an outer fabric (3) of upholstery made with a fire-retardant thread known to those skilled in the art.
  • the interior padding (4) is made of polyurethane foam with poor fire-fighting properties.
  • a fire-resistant textile barrier (5) is interposed between the padding foam (4) and the lining fabric (3) to protect said foam (4) from the external action of a flame.
  • FIG. 2 This arrangement is taken up in FIG. 2 illustrating in section view an exterior lining fabric (3), an intermediate fire-resistant textile barrier (5) and an interior polyurethane padding foam (4).
  • the textile fire barrier of the present invention calls for the use of polyacrylate fibers. It is a material having excellent fire-fighting characteristics but which cannot be spun to date and which consequently is in the form of quilted, polymerized or needled plies after carding.
  • Polyacrylate fibers resist the action of heat and that of chemicals. In addition, in the event of a fire, their degradation is minimal, which prevents the formation of smoke and gas.
  • the fibers exhibit good intrinsic behavior in the event of a fire, but the sheet produced suffers from cracking problems which create gaps revealing the polyurethane foam which, through these cracks, is subjected to the direct action of the flame. with the consequences that flow from it.
  • the polyacrylate sheet chars without flame and falls to dust after a certain time, the product turns yellow then blackens and chars in about fifteen minutes.
  • the fire-resistant textile barrier (5) consists of a sheet of non-woven and fire-resistant fibers of the polyacrylate type reinforced by flexible means providing the whole with a uniform hold of the skeleton. charred.
  • a core of glass threads is incorporated to contain the sheet and thus keep a homogeneous network of fabric.
  • the glass strands make it possible to avoid the formation of cracks by spreading the polyacrylate fibers. This solution is satisfactory with regard to the first category of tests, that is to say when the flame does not exert a mechanical blast action.
  • the fire-resistant textile barrier of the present invention consists in particular of flexible means which ensure mechanical cohesion of the entire charred skeleton of the textile barrier. This mechanical cohesion allows the barrier to also resist the blast of the flame.
  • the shape given to the padding (4) is retained at the start of the fire and throughout it, cracks and punctures are avoided so that the flame cannot penetrate inside. padding (4).
  • the cushion is only subjected to the action of heat, which makes it partially melt, but the foam does not ignite. Tests at 1040 ° C for two minutes showed that the cushions had a weight difference of less than 10% after the test.
  • Flexible means ensuring mechanical cohesion of the whole are in the form of aramid, aromatic polyamide, polybenzimidazol (PBI) or wool fibers. These fibers are intimately mixed with the polyacrylate fibers to form a homogeneous composition.
  • Aramid fibers have excellent mechanical resistance thanks to an important molecular orientation. Despite their loss of resistance with the rise in temperature, the aramid fibers, which do not burn, allow the carbonized skeleton to retain a mechanical cohesion preventing the formation of cracks even under the action of the burner at 1040 ° C.
  • composition comprising more than 30% of aramid fibers is very difficult to work in a mixture which becomes less intimate and risks of heterogeneous mechanical resistance exist.
  • a minimum threshold of 5% of aramid fibers must be reached for the mixture to be able to effectively act as a fire barrier.
  • the polyacrylate fibers used are sold by the company COURTAULDS under the name of "INIDEX”.
  • the aramid fibers used are sold by the company DU PONT DE NEMOURS under the name of "KEVLAR”.
  • An intimate and homogeneous mixture of these nonwoven fibers is produced from 80% polyacrylate fibers and 20% aramid fibers.
  • the manufacturing comprises a first carding step which makes it possible to obtain a veil which is then coated by superposition to form a barrier with a thickness of approximately four millimeters.
  • the homogeneity of the whole is achieved by needling.
