Definitions

  • the present invention relates to fabrics, sheet or tablecloth, intended to make protective clothing, including jackets intervention of people to be subjected to extreme conditions, especially in the case of fire.
  • It relates in particular to a new type of material that can be used to make firefighters' clothing, without excluding other applications.
  • WO-A-99 05926 describes an insulating material that can have different levels of thermal insulation depending on the conditions.
  • meta-aramids include the polymer sold by KERMEL Company under the same name, the fibers sold under the trademark " NOMEX” by the company DUPONT DE NEMOURS and those marketed under the trademark " CONEX” by TEIJIN.
  • the invention therefore relates to the sector of producing multilayer materials as illustrated in FIG.
  • a problem arises with regard to the thermal barrier, generally constituted by needle felt, and the finishing lining located on the user's side.
  • the complexes proposed to date have a disadvantage that lies essentially in the fact that the clothes made lack comfort both physically and physiologically. In addition, under certain conditions, they lack effectiveness.
  • heat stress is a condition in which the body can no longer maintain a temperature below 39 ° C, resulting in in addition to a loss of physical capacity, loss of lucidity, fainting or cardiac arrest.
  • Such a state of stress is caused, in particular by the weight of equipment that can exceed 20 kilograms, and the sometimes too insulating capacity of their protective clothing.
  • thermal barrier allows moderate insulation in a normal situation by the fact that it has a low thickness and a low thermal load, which improves comfort and which, depending on the increase of the temperature, allows to have an increase of the insulation, this increase being able to be localized to the zones where the heat is the most important when the user is confronted with a situation of urgency in the face of fire.
  • a warp of the upper face may, in a predetermined sequence, be linked with a frame (or pick) of the lower face.
  • This link can to be made according to any type of pattern, conventionally to form lozenges or tubes.
  • reverse faces and locations of different colors are reversed to obtain a decorative effect, which is not desirable in the context of the invention where each face must have a specific function.
  • such double-sided structures can also be made by knitting, either according to the stitch technique or by the technique of knit stitch, more particularly on knitting chain or Rachel knitting.
  • the layer having a shrinkage under the effect of heat consists, in whole or in part, of son having a shrinkage under said effect of heat.
  • the bags constitute channels, only the family of wires perpendicular to said channels, considered in whole or in part, having a shrinkage under the effect of heat.
  • the effect of removal of the layer of the thermal barrier may result from the presence of a membrane attached to said layer, or a coating.
  • the basic structure according to the invention is constituted by a pocket fabric comprising an inner layer designated by the general reference (1), an outer layer designated by the general reference (2) these two layers being contiguous to one another and being intermittently bonded together by a selection of warp threads (3) selected from among those constituting the inner layer.
  • the connecting lines (3) form, between them, flat pockets formed between the inner layer (1) and the outer layer (2).
  • the warp yarns (C1) intended to form the inner layer (1) on the lining side, as well as the weft yarns (T1), consist of yarns and more particularly fiber yarns having practically no shrinkage power under the effect of intense heat.
  • the warp yarns (C2) intended to constitute the outer layer (2) consist, in turn, of yarns having a slight shrinking power with respect to the yarns (C1).
  • the weft threads (T2) intended to constitute the outer layer are also based on yarns having no shrinkage power.
  • the temperature reached by the outer layer (2) is high, for example in the case of the use for making the meta-aramid thread son son such as, for example: isostamides and polyaramides, a temperature of the order of 300 ° C, there is a retraction of the external chain (C2) which causes a rimpedement generatrices (3) of the connecting areas.
  • the layer (1) is, in turn, dimensionally stable to heat, and is otherwise protected in part by the outer layer, this causes the creation of a relaxation of the inner side, and thus the formation of pockets in relief .
  • a complex according to the invention of the type illustrated in FIG. 2 is produced, the weave of which is illustrated in FIG.
  • the chain (C1) intended to form the face directed towards the user, and the weft (T1) also intended to form this face, are made from a mixed fiber yarn comprising polyamide imide fibers (KERMEL) and FR viscose fibers (containing a flame retardant), in a 70/30 mixture, the title of these yarns being equal to Nm 70/2.
  • KERMEL polyamide imide fibers
  • FR viscose fibers containing a flame retardant
  • This face of the fabric has 26 threads / cm and 24 picks / cm.
  • the chain (C2) which has this heat-shrinkable property and which constitutes the insulating layer is, for its part, made of a 100% fiber yarn based on polyamide imide fibers marketed under the trade name KERMEL TECH, the title of these wire being Nm 60/2.
  • the chain density (C2) is 13 threads / cm.
  • the frame (T2) is, for its part, identical to the internal frame and its density is 12 picks / cm.
  • this complex fabric is about 230 g / m2.
  • the internal face (1) the most contextured, thus acts as a lining, and is the one that is directed to the user.
  • the face (2) consisting of heat-shrinkable son in the chain is that which serves as a thermal barrier.
  • the invention relates to any multilayer complex material in sheets for the purpose of producing a thermal barrier composed of a first and a second layer by producing a superposed double-sided structure connected intermittently, so as to form pockets.
  • the layers are bonded by intermittently bonding a selection of wires.
  • One of the layers has shrinkage under the effect of heat. This shrinkage effect is obtained, if one considers the illustrated example, on all or part of the connecting son constituting the pockets.
  • this effect of removing one of the layers can also result from the presence of a membrane fixed on the layer in question.
  • this membrane may be made of any material capable of exhibiting a shrinkage under the effect of heat such as microporous polyurethane, hydrophilic polyurethane, hydrophilic polyester,
  • the layer of the complex material may be subjected to a coating operation such as polyurethane, PVC, silicone, ..., to create the desired shrinkage effect under the action of heat.
  • a coating operation such as polyurethane, PVC, silicone, ...
  • this complex does not present the aging problems of conventional needle felt (fiber migration, compaction, ...), nor the abrasion problems experienced or created by the thermal barriers having a permanent relief.
  • this new thermal barrier makes it possible to visualize the state of degradation of the complex. Indeed, the reaction being only in extreme situation, it corresponds to a loss of efficiency of the outer fabric and especially the membrane generally associated in this type of clothing.
  • channel-shaped pockets in the double fabric according to the invention will preferably be arranged vertically in the garment to prevent the slight perpendicular retraction up the bottom of the jacket and sleeves .
  • This slight tightening of the layer in question on the body of the wearer is not problematic, because it is actually a redistribution of the protective air contained in the garment automatically favoring the places where the heat is punctually the highest.
  • multilayer complex material according to the invention may advantageously be combined with a structure also including an outer fabric and a breathable inner membrane generally associated with a substrate in accordance with the general features illustrated in FIG.
