  • the textile part 1 is solely formed by first threads 2a. In another embodiment, the textile part 1 is formed by first threads 2a and at least one additional thread 2b, preferably several additional threads 2b identical or different from each other.
  • Each first wire 2a has a core 4 of first material and a sheath 5 of second material different from the first material.
  • the first material is para-aramid, carbon fiber or glass fiber.
  • the first material is a para-aramid.
  • the second material forms the sheath 5, that is to say a protective layer around the core 4.

  • the first material has the highest value of resistance to rupture in the longitudinal direction above 50°C, preferably above 100°C and advantageously above 150°C relative to the sheath and preferably in relation to the other materials forming the textile part.
  • the core 4 also provides the characteristics relating to heat resistance according to the ISO17493 standard. It is advantageous for the core 4 to be formed in the material which has the highest heat resistance value of the textile part. It is advantageous to choose a core 4 made of first material whose title is between 110dTex and 8250dTex and in particular para-aramid.
  • the textile part 1 can be formed by different first threads 2a whose title is included in the previous range. The choice of title is made according to the needs to be achieved.
  • the interweaving of the first wires 2a with other wires 2b and preferably the interweaving of the first wires 2a between them makes it possible to define the resistance to piercing of the textile part 1 or the resistance to punching.
  • the type of interlacing as well as the tension in the first thread 2a during the interlacing step makes it possible to define the resistance to piercing of the textile part 1.
  • the sheath 5 forms a shell around the core 4 so as to reduce the aging of the core 4.

  • a textile devoid of a coating layer the sheath 5 of each first thread 2a is spaced from the sheath of the adjacent threads (first threads 2a or other threads 2b) by an empty zone.
  • the use of a textile whose sheath 5 of each first yarn 2a is spaced from the sheath of the yarns (first yarns 2a and second yarns 2b) adjacent by an empty zone is particularly advantageous because it makes it possible to form a material with high breathability.
  • Such a configuration makes it possible to form a fabric whose air permeability is greater than 300L/m 2 /s at 200Pa, or even 700L/m 2 /s at 200Pa.
  • the air permeability measurement is carried out in accordance with the ISO9237 standard. It is particularly advantageous to form a textile part 1 whose air permeability is between 300L/m 2 /s and 1200L/m 2 /s at 200Pa.
  • a thin coating layer may be possible in addition to the sheath 5.
  • the coating layer is a layer of a more flexible material than the second material forming the sheath 5.
  • the layer is more flexible than the second material so as not to degrade the flexibility of the textile.
  • first threads 2a are each covered by a sheath 5 distinct from each adjacent thread (in particular the first threads 2a), for an identical or substantially identical thickness of the same second material.
  • This configuration is advantageous compared to a coating layer common to several threads having a core of first material and in particular of para-aramid, the coating layer having a thickness identical to the sheath and being made of this same material.
  • the configuration is advantageous because it has better abrasion resistance.
  • the sheath 5 is more resistant to abrasion, it provides the protective characteristics of the core 4 for longer for washing operations and against attacks from ultraviolet radiation. Replacing the coating layer with the sheath 5 makes it possible to increase the lifespan of the cores 4 made of first material.
  • a sheath 5 independently protecting each core 4 and in a configuration devoid of a coating layer makes it possible to form, in addition, a fabric with better breathability. Breathability can be represented by the amount of air that can pass through a given surface of textile per unit of time.
  • the use of a textile comprising the first yarns 2a makes it possible to form a fabric having a breathability greater than or equal to 200L/m 2 /s at 200Pa.
  • the sheath 5 has a breaking strength along the longitudinal axis which is lower than the breaking strength of the core 4. It is advantageous for the sheath 5 to have an elastic limit at breaking which is greater than that of the core 4, preferably at least 50% higher. Preferably, the elastic limit at rupture of the sheath 5 is 500 times greater than that of the core 4.
  • the sheath 5 is made of a material which is devoid of glass transition temperature in a range between -20°C and 210°C in order to avoid a significant modification of the mechanical behavior when the temperature changes in this range. It is advantageous for the material of the sheath 5 to be between 3 and 10 MPa so as to have an interesting behavior for clothing.
  • the elongation at break of the sheath 5 is between 500% and 1500% in order to better adapt to the needs of a garment and in particular to the needs of fire protection clothing. It is also preferable that the material forming the sheath 5 has a degradation temperature greater than 210°C and more preferably greater than 230°C. The degradation temperature may be the melting temperature. It is also preferable that the material of the sheath 5 is not brittle at a temperature equal to -20°C so as to allow its use in clothing over a wide range of use temperatures.
  • the sheath 5 of a first wire 2a is distinct from the sheath 5 of an adjacent first wire 2a or from the sheath of an adjacent wire 2b.
  • the core and the sheath can be made of identical or different materials.
  • Such a configuration makes it possible to form a porous textile part 1.
  • the sheath 5 of a first wire 2a is mechanically connected to the sheath 5 of an adjacent first wire 2a or to the sheath of an adjacent wire 2b by means of a layer which is more flexible than the second material forming the sheath 5.
  • the flexibility of the layer makes it possible to have a textile part 1 whose flexibility provided by the interweaving is not or is only slightly modified by the addition of the layer.
  • the flexibility of the layer will result in rapid wear so that the layer is incapable of providing good sealing over time and/or good protection against UV radiation.
  • the material forming the layer may also have a melting temperature which is lower than the melting temperature of the sheath 5.
  • a textile which is devoid of a coating layer or whose areas having a coating layer do not face surfaces generating perspiration.
  • the coating layer blocks air and water so that the user's sweat cannot escape, which is unpleasant.
  • it is sought to form a thick coating layer which strongly modifies the mechanical behavior of the textile and blocks the passage of air and water.
  • the second material forming the sheath 5 is preferably chosen from polyurethane-ether, polyurethane-ester, polyurethane polyacrylate, silicone, a polyolefin, a thermoplastic polyurethane (TPU) or a mixture of these. These materials are particularly advantageous for forming a sheath 5 which is effective in blocking water as well as UV radiation with a low thickness which makes it possible not to modify too much the mechanical behavior of the core 4.
  • a flame retardant be used in the sheath 5. It is also possible to use a second material which contains a flame retardant polymer, preferably at least 5% by weight. Preferably, the flame retardant is an organo-phosphorus compound. It is also possible to use a flame retardant elastomer. It is then advantageous to provide a sheath 5 whose title is between 30dTex and 3000dTex.
  • one or more compounds to the second material so as to improve its technical characteristics, for example by adding one or more polymer materials, one or more elastomers, polymer particles, particles minerals or even metallic particles. It is possible to add a compound intended to improve the abrasion resistance of the sheath. It is possible to add a compound intended to improve the blocking power of UV radiation. It is possible to add a compound intended to improve resistance to ozone. It is possible to add a compound intended to improve Infrared camouflage. It is possible to add a compound intended to improve water repellency. It is possible to add a compound intended to reduce the wicking effect. It is possible to add a compound intended to improve resistance and/or repellency to chemicals.
  • the textile part 1 is configured so that the sheath 5 of each first wire 2a can be movable relative to the adjacent wire of the part textile 1. Mobility can be observed along the longitudinal axis of the first thread 2a as well as perpendicular to the longitudinal axis. The sheath 5 does not stick to the adjacent wire 2. The deformation of the threads 2 relative to each other makes it possible to provide better flexibility of the textile part 1 compared to the configurations of the prior art. In other words, the textile part 1 does not have a coating layer which continuously connects several first adjacent threads.
  • the formation of a porous textile part 1 is advantageous because it allows at least one flow of air to pass through the two opposite faces of the textile part 1.
  • the textile part 1 does not have a coating layer, it is possible to choose an interweaving configuration which makes the circulation of air through the textile part 1 more or less easy. It is also possible to choose a configuration interlacing which authorizes or prohibits the passage of humidity through the textile piece 1.
  • the interlacing configuration can be defined by the weave of the weave as well as by the number of threads 2 per surface unit. For a given diameter of wires 2, the greater the number of wires 2, the tighter the weaving, which modifies the permeability to air and water. It is possible to modify the number of warp threads for a unit of weft distance and it is possible to modify the number of weft threads for a unit of warp distance. This information can be provided in the form n threads / cm for the weft and/or the warp.
  • the interlacing configuration is chosen so that the textile part is watertight.
  • the interlacing configuration is chosen so that the textile part allows water to pass through.
  • a compromise is found in the interlacing configuration between the ability to let air and possibly water vapor pass through and resistance to abrasion and possibly punching.
  • the interlacing configuration of the textile part 1 will be adjusted. It is possible to choose one weave or another so as to promote or block the passage of air between one side of the textile piece 1 and the other side. It is also possible to choose the percentage of occupation by the threads for a given surface unit so as to modulate the capacity to allow the passage of air between one side of the textile piece 1 and the other side. The same goes for the ability to circulate water. It is possible to form a garment with several different zones. The zones are distinguished by a difference in weave and/or by a difference in the number of threads/cm.
  • first thread 2a which has a core 4 of first material and in particular of para-aramid covered by a protective sheath 5 which is specific to it makes it possible to form a textile part 1 whose performance is better preserved over time, particularly after multiple washes with water and after a period of exposure to ultraviolet radiation. It is possible to form a textile part 1 which is more flexible than the coated configuration of the prior art and which allows better ventilation while offering as good or even better performance over time.
  • the textile part 1 has a content of first threads 2a which is greater than or equal to 10%, the content is in number of threads.

  • Such breathability value is much higher than which is observed with a leather jacket or a jacket covered with a coating layer without degradation of fire resistance performance.
  • the content of first threads 2a corresponds to the number of first threads 2a out of the total number of threads for a given surface unit, for example 1cm 2 . It is particularly advantageous that the surface proportion of first wires 2a is never less than 10%, that is to say that the surface occupied by the first wires 2a is greater than 10% for a given unit of surface, for example 1cm 2 . Preferably, the content of first son 2a is greater than or equal to 30%, or even 50%. The more the content of first wires 2a increases, the more the mechanical performance at high temperature increases.
  • first yarns 2a having a core of first material and preferably para-aramid makes it possible to form a textile part 1 which has good resistance to opening under the effect of a flame and convective heat.
  • the content of first wires 2a is adapted. The more the content of first wires 2a increases, the more the resistance to opening under the effect of a flame and convective heat increases.

  • the textile part 1 is formed with a first thread 2a whose core 4 is in the form of a long fiber, that is to say that the core 4 is formed by one or more filaments which extend continuously from one end to the other of the textile piece 1.
  • the core 4 is formed by several filaments, the majority or all of the filaments extend continuously from one end to the other of the textile part 1.
  • the textile part has para-aramid threads whose core is formed with short fibers which are linked to each other. It is advantageous for the sheath 5 to also be in the form of a sheath 5 which extends continuously and monolithicly from one end to the other of the textile part 1.
  • the same first thread 2a can extend continuously several times from one end to the other.
  • the same first thread 2a forms several weft threads, preferably several adjacent weft threads.
  • the continuity of the weft threads can disappear once the textile piece 1 is cut to the shape of the garment 3 or part of the garment 3.
  • Pilling resistance can be quantified by the modified Martindale method (ISO12945-2-2000 standard). Better resistance to pilling allows the textile part 1 to be kept for longer.
  • first yarns 2a with long fibers makes it possible to form a textile part 1 whose yarns 2 are less tight against each other, which improves the thermal evaporative resistance called RET (in m 2 .Pa/W), that is to say the resistance that a fabric offers to the evacuation of humidity. This resistance value is measured according to the ISO11092 standard.
  • the textile part 1 has a first portion 1a and a second portion 1b.
  • the first portion 1a and the second portion 1b share at least one first wire 2a, preferably several first wires 2a. It is particularly advantageous that the first portion 1a and the second portion 1b come from the same manufacturing step of the textile part 1, for example the same weaving step, the same knitting step or the same braiding step.
  • the first portion 1a has a first thermal evaporative resistance value and the second portion 1b has a second thermal evaporative resistance value which is different from the first thermal evaporative resistance.
  • the first portion 1a has a first air permeability value and the second portion 1b has a second air permeability value which is different from the first air permeability value.
  • the first portion 1a has a first water permeability value and the second portion 1b has a second water permeability value which is different from the first water permeability value .
  • the first portion 1a has a first opening value to flame or convective heat and the second portion 1b has a second opening value to flame or heat convective which is different from the first value of opening to the flame or to convective heat.
  • the first portion 1a has a first mass value per unit area and the second portion 1b has a second mass value per unit area which is different from the first mass value per unit area .
  • the first portion 1a has a first abrasion resistance value and the second portion 1b has a second abrasion resistance value which is different from the first abrasion resistance value .
  • the first portion 1a has an interleaving configuration which is different from the interleaving configuration of the second portion 1b.
  • the first portion 1a has a content of first wire 2a which is different from the content of first wire 2a in the second portion 1b as is illustrated in figures 2, 3 and 4 .
  • the first portion 1a has a content of first additional wire 2b which is different from the content of first additional wire 2b in the second portion 1b.
  • the textile piece 1 forms all or part of a garment 3, for example a jacket.
  • the first portion 1a and the second portion 1b have different mechanical and/or thermal performances, which makes it possible to use the same textile piece to form several different parts of the garment 3.
  • the different parts of the garment 3 must meet different needs.
  • the steps of making the garment 3 are reduced, which makes it possible to reduce the manufacturing cost and this makes it possible to improve the compromise between strength and mass.
  • the textile part 1 may include a portion which has a low water permeability on the front face of the garment 3 and a water permeability which is high on the rear face of the garment 3 or the reverse depending on the identified needs. These two portions belong to the same monolithic textile part 1 and come from the same manufacturing step, for example the same weaving, knitting or braiding step.
  • two portions 1a and 1b are represented, but it is possible to produce three, four or more different portions.
  • the portions differ from each other by one of the parameters identified above: thermal evaporative resistance, resistance to opening under the effect of a flame or under the effect of convective heat, permeability to air, water permeability, abrasion resistance, pilling resistance.
  • the textile part 1 is particularly advantageous for forming all or part of a firefighter's jacket intended to fight fire. This allows us to provide a textile part 1 which differentiates between zones intended to resist intense heat and zones better suited to promoting the evacuation of perspiration.
  • the textile part 1 can also form all or part of a motor vehicle driver's suit.
  • the thermal constraints are approximately identical to those of firefighter clothing because it is necessary to be able to wick away perspiration throughout the race without neglecting flame resistance when an incident occurs.
  • Textile part 1 may be a textile piece of luggage.
  • the textile part can be a furnishing textile part in order to better meet the constraints on flame-retardant textiles.
  • the textile part 1 can be part of a piece of furniture, for example an armchair, a sofa, a seat.
  • the textile part 1 has meta-aramid threads and para-aramid threads in order to combine the advantages of each of the threads.
  • the meta-aramid yarns and the para-aramid yarns are bonded together so as to form only one yarn.
  • meta-aramid fibers and para-aramid fibers are combined together during the same spinning step.
  • the sheath is formed around the para-aramid and meta-aramid wire.
  • the internal ply is formed mainly or exclusively by meta-aramid threads while the external ply is formed mainly or exclusively by para-aramid threads each coated by a sheath 5. The reverse is also possible.
  • the textile part 1 is obtained by weaving.
  • the first threads 2a belong at least to the warp threads and they can belong to the warp threads and the weft threads.
  • a fabric 1 obtained by weaving has at least one warp thread as well as several weft threads as is illustrated in Figure 1. figure 2 .
  • the at least one warp thread and the weft threads are identical. If fabric 1 is formed by several warp threads and/or several weft threads, the latter are then identical.
  • fabric 1 is obtained by knitting as illustrated in Figure 3 , the threads forming the knitting are preferably identical. It is the same if fabric 1 is obtained by braiding as illustrated in Figure 1. figure 4 .
  • the fabric 1 has different threads.
  • the wires are different in their mechanical performance and/or in their compositions. If the fabric 1 is obtained by weaving, it is possible to use several weft threads and/or several warp threads and at least one of the threads is different from the first thread 2a. If the fabric 1 is obtained by knitting, it is possible to use several threads, at least one of which is different from the first thread 2a. If the fabric is obtained by braiding, it is possible to use several threads, at least one of which is different from the first thread 2a.
  • the Figure 3 illustrates an embodiment of which at least one additional wire 2b is different from the first wire 2a.
  • the sheath 5 can be formed around the core 4 by any known process, for example by coating, by extrusion, by physical vapor deposition or by chemical deposition, for example by a sol-gel process.
  • first yarn 2 which has a title of between 50dTex and 3300dTex.
  • the choice of the title of the first thread 2 can be made according to the expected flexibility characteristics. If fabric 1 is formed by several threads, it is advantageous for all the threads to have a title of between 50dTex and 3300dTex.
  • the core of the first wire 2a has a tenacity of between 6cN/Tex and 40cN/Tex.
  • Such toughness makes it possible to have a fabric 1 particularly well suited to resist the deformation of the fabric 1 without breaking.
  • the fabric 1 has a surface mass of between 110g/m 2 and 500g/m 2 .
  • the surface mass of the fabric 1 can be defined by judiciously choosing the title of the thread(s) forming the fabric and the weave of the fabric 1.
