Definitions
- the present invention relates to a fabric, in particular usable in the manufacture of clothing for personal protection, comprising at least one high-performance thermoplastic yarn such as an aromatic polyester yarn.
- the invention also relates to a garment for personal protection comprising such a fabric, in particular in the outer layer of said garment.
- Fabrics made of cotton or cotton/polyester blends flame retarded by means of a chemical treatment have been proposed.
- the fireproofing of these textiles consists of impregnation using baths comprising metal salts.
- such textiles have a relatively high surface density, for example of the order of 300 g/m 2 or more, in order to be able to meet the protection standards in force.
- Such a high basis weight makes the garment comprising such a textile not very comfortable.
- This type of textile can also be blamed for a significant alteration of the touch during use, also affecting the comfort of the user.
- the durability of the fire-resistant properties of such textiles may be insufficient and requires taking a certain number of maintenance precautions so as not to alter these textiles, in particular during cycles. washing.
- Textiles comprising heat-stable, fire-resistant fibers are also proposed, such as in particular fibers based on aramid, whether it is the meta-aramid PMIA or the para-aramid PPTA.
- Such textiles have good durability, good mechanical performance and good thermal protection properties. Usually transformed into an intimate mixture, these fibers are very widely used in the manufacture of equipment with high level requirements, in particular for firefighting equipment or for the police forces.
- a high percentage of para-aramid PPTA in a textile gives the latter interesting properties, namely a good level of flame resistance, no "break open", that is to say a good ability to textile to resist the opening of the textile under the effect of flame and heat, and low thermal shrinkage during a flashover.
- EP 2 762 618 A1 discloses a fabric comprising an arrangement of yarns arranged in a weave pattern forming a face of the fabric and a back of the fabric, said arrangement of yarns comprising one or more warp yarns and one or more weft yarns comprising aromatic polyester.
- the present invention aims to remedy this need by proposing a fabric comprising at least one yarn based on aromatic polyester, this fabric having in particular particularly remarkable mechanical and anti-fire properties while having a surface mass allowing optimal comfort for the user.
- the present invention relates to a fabric comprising an arrangement of yarns arranged in a weave pattern forming a face of the fabric and a reverse side of the fabric, said arrangement of yarns comprising one or more warp yarns and one or more weft yarns, characterized in that at least one of said warp yarns and said weft yarns is an aromatic polyester yarn, the other yarns being made of a material other than aromatic polyester, said aromatic polyester yarn being bonded to the other yarns within of the weaving weave so that this aromatic polyester yarn does not appear on the face of the fabric.
- the aromatic polyester yarn or yarns of the fabric according to the invention can be in the form of fiber spun yarns or continuous filaments. These yarns are produced from an aromatic polyester, a polyarylate, which is a liquid crystal thermotropic polymer. This polymer is obtained by the polymerization of parahydroxybenzoic acid with 6-hydroxynaphthalene-2-carboxylic acid. The molecular chain of this liquid crystal polymer has a very high degree of orientation in the direction of the length of the fiber, which gives the yarn spun from these fibers excellent physical properties.
- An aromatic polyester yarn particularly suitable for the manufacture of the fabric according to the invention is the aromatic polyester yarn sold under the trade name “ Vectran® ” by the company Kuraray. Due to its decomposition temperature above 400°C, such a wire has a very high resistance to heat. Moreover, when this wire is subjected to a strong source of heat, no toxic gas is emitted. Thus, the fabric according to the invention has good heat resistance as well as good chemical behavior under the conditions in which it can be used when it contributes to the manufacture of personal protective clothing such as intended to be worn by firefighters.
- the weaving weave of the fabric according to the invention can be a complex weaving weave making it possible to obtain different functionalities and/or aspects on the front side and on the reverse side of the fabric.
- the aromatic polyester yarn can thus be bonded to the yarns constituting the face of the fabric, without however appearing on the face of the fabric.
- the fabric according to the invention has excellent resistance to abrasion, in particular on its face, free of aromatic polyester yarn.
- the particular construction of the fabric according to the invention allows the aromatic polyester yarn to retain its integrity throughout the period of use of the fabric. The fabric thus retains its mechanical properties throughout the life of the fabric/garment.
- the other yarns forming the warp yarns and the weft yarns of the face of the fabric only the aromatic polyester yarns forming the warp yarns on the back of the fabric are linked to the other yarns by binding stitches.
- This embodiment of the weaving weave which ensures that the aromatic polyester yarns forming the weft yarns of the back of the fabric are not bound to the yarns forming the face of the fabric, guarantees the absence on the face of the fabric of the aromatic polyester weft yarns from the back of the fabric.
- the aromatic polyester yarns forming the warp yarns of the back of the fabric are linked to the other yarns at points chosen so that these aromatic polyester warp yarns do not appear on the place of the fabric.
- the aromatic polyester yarns are present in the fabric according to the invention in a proportion ranging from 10% to 25% by mass, preferably from 17% to 22% by mass, more preferably from 18% to 22% by mass, relative to the total mass of said tissue.
- the fabric thus has both good mechanical properties and good fire-retardant performance, while remaining within a range of surface mass allowing user comfort.
- the aromatic polyester yarns of the fabric according to the invention can be chosen from yarns of aromatic polyester fibers, continuous filaments of aromatic polyester and mixtures thereof.
- the aromatic polyester continuous filaments that can be used for the fabric according to the present invention preferably have a count ranging from 110 dtex to 880 dtex, preferably from 220 dtex to 440 dtex. Such a titration allows the yarns used to bring a certain resistance to the fabric while not overloading the latter too much by weight.
- one or more of the aromatic polyester yarns may be a cracked yarn. The mechanical resistance of the wire is thus increased.
- one or more of the aromatic polyester yarns is wrapped yarn, for example with a polyamide yarn.
- a covered yarn makes it possible to impart an external color to the aromatic polyester yarn, for example by dyeing the polyamide yarn.
- a covered yarn also makes it possible to improve the process of weaving of the fabric, by protecting the aromatic polyester yarn instead of the sizing oils usually used during the weaving process, these oils being poorly compatible with aromatic polyester yarns.
- one or more aromatic polyester yarns can be covered with a colored coating.
- the fabric according to the invention comprises yarns other than the aromatic polyester yarn or yarns described above. These other yarns generally form the basic structure of the fabric and are chosen from any yarn suitable for the manufacture of a fabric in particular for personal protection.
- These threads can be made of a material chosen from meta aramid, para aramid, viscose, cellulose, modacrylic, polybenzimidazole (PBI), poly( p -phenylene-2,6-benzobisoxazole) (PBO) and their mixtures.
- these yarns are chosen from yarns made up of fibers chosen from meta-aramid fibers, para-aramid fibers, antistatic fibers, cellulosic fibers and mixtures of these fibers, in particular from meta-aramid fibers.
- the yarns other than the aromatic polyester yarns form the face of the fabric according to the invention and can be arranged according to any known weave, for example a Ripstop weave, a Micro-Ripstop weave, a Twill weave or even any other weave. more elaborate.
- the type of weave of the fabric according to the invention is adapted, depending on the type and the count of the yarns forming the fabric, both of the aromatic polyester yarns and of the other yarns, so that the binding points of the polyester yarns aromatic with the other threads do not appear on the face.
- the aromatic polyester yarns are integrated into the internal structure of the fabric and do not appear on the face.
- Aromatic polyester threads may appear on the back of the fabric.
- the fabric according to the invention preferably has a surface mass ranging from 210 g/m 2 to 260 g/m 2 , preferably from 220 g/m 2 to 250 g/m 2 .
- the fabric according to the invention has a lightness making it particularly suitable for the manufacture of clothing for personal protection.
- the low surface mass of the fabric according to the invention makes it possible to manufacture comfortable personal protective clothing.
- the fabric according to the invention has very good mechanical properties, for example excellent mechanical strength both in warp and in weft.
- the fabric according to the invention has a mechanical warp resistance, measured according to standard NF EN ISO 13934-1, ranging from 190 daN/5cm to 288 daN/5cm, for example ranging from 190 daN/5cm to 250 daN /5cm.
- the fabric according to the invention has a mechanical strength in the weft, measured according to standard NF EN ISO 13934-1, ranging from 190 daN/5cm to 295 daN/5cm, for example ranging from 190 daN/5cm to 250 daN /5cm.
- the fabric according to the invention also has excellent tear resistance.
- the fabric according to the invention has a warp tear resistance, measured according to standard EN 13937-2, ranging from 15 daN to 27 daN.
- the fabric according to the invention has a weft tear resistance, measured according to standard EN 13937-2, ranging from 16 daN to 40 daN.
- the fabric according to the invention also has excellent cut resistance.
- the fabric according to the invention has a cut resistance, measured according to standard NF EN ISO 13977, ranging from 3.8 N to 4.7 N.
- the present invention also relates to personal protective clothing, in particular fireproof, comprising at least one fabric as described above, said fabric forming at least an outer part of said garment.
- personal protective clothing in particular fireproof, comprising at least one fabric as described above, said fabric forming at least an outer part of said garment.
- the face of the fabric according to the invention free of aromatic polyester yarn, will be placed on the outer surface of said garment.
- Such a garment will thus have excellent abrasion resistance.
- the “ Vectran® ” yarns have undergone a cracking treatment: they are therefore cracked “ Vectran® ” yarns; these yarns have a reinforced mechanical resistance compared to “ Vectran® ” yarns which have not undergone any cracking treatment.
- the weaving weave used to make CLOTH 1 is shown in the Figure 1 .
- This representation is well known to those skilled in the art.
- the weft threads are shown parallel to the horizontal direction TR, and the warp threads parallel to the vertical direction CH.
- a gray box indicates that the warp yarn is above the weft yarn
- a white box indicates that the weft yarn is above the warp yarn.
- threads 1 of cracked “Vectran ®” are present in the weave of the fabric both in warp and weft threads, and threads 2 of "Nomex ® N302" are also present in the weave in both warp and weft threads.
- This weaving weave means that the cracked “Vectran ® " threads 1 are bound to the other threads, here the "Nomex ® N302" threads 2, by binding points which are present in the heart of the fabric and/or on the reverse, but which are absent on the front. Thus, the cracked “ Vectran® ” threads 1 do not appear on the face of the fabric.
- the mass percentage of aromatic polyester yarns in other words of cracked “ Vectran® ”, is 17% by mass, relative to the total mass of the fabric.
- FABRIC 1 has a surface weight of 240 g/m 2 .
- TISSU 1 The mechanical strength and fire resistance properties of TISSU 1 were compared to those of a prior art fabric, TISSU 0.
- FABRIC 0 is a fabric comprising yarns mixing 93% meta-aramid fibers, 5% para-aramid fibers and 2% antistatic fibers sold under the trade name “ Nomex® N302”, with a count of 50/2Nm. FABRIC 0 does not include aromatic polyester yarn. It is composed solely of "Nomex ® N302" threads with a count of 50/2Nm, in warp and weft. The surface mass of TISSUE 0 is 240 g/m 2 .
- the weft mechanical resistance of FABRIC 1 is practically 1.4 times greater than that of FABRIC 0.
- the warp tear resistance of FABRIC 1 is 1.5 times greater than that of FABRIC 0.
- CM multilayer complex
- first layer corresponding to the fabric to be tested
- second layer comprising a nonwoven fabric complexed with a membrane
- third layer composed of a conventional fabric used in firefighter applications.
- the second and third layers were therefore identical for all the multilayer complexes.
- Table 2 fire resistance properties for CM TISSU 0 and CM TISSU 1
- the FABRIC 1 according to the invention has properties of mechanical strength and fire resistance superior to the FABRIC 0 according to the prior art, free of aromatic polyester threads.
- the “ Vectran® ” yarns are wrapped with a polyamide 66 yarn with a count of 44 dtex.
- This weaving weave means that the yarns 3 of covered “Vectran ® " are linked to the other yarns, here the yarns 4 of "Nomex ® N302", by binding points which are present in the heart of the fabric and/or on the reverse, but which are absent on the front. Moreover, according to this weaving weave, only the covered “ Vectran® ” yarns which form the warp yarns of the back of the fabric are bonded to the “ Nomex® N302” yarns forming the face of the fabric. The covered “Vectran ® ” yarns which form the weft yarns on the back of the fabric are not bonded to the “Nomex ® N302” yarns forming the face of the fabric. Thus, the covered “ Vectran® ” yarns 3 do not appear on the face of the fabric.
- the mass percentage of aromatic polyester yarns in other words “ Vectran® ”, is 19.5% by mass, relative to the total mass of the fabric.
- FABRIC 2 has a surface mass of 225 g/m 2 .
- FABRIC 2 The mechanical strength and fire resistance properties of FABRIC 2 were compared to those of the fabric of the prior art described in EXAMPLE 1, namely FABRIC 0. The tests of this example were carried out according to the same protocols than those of EXAMPLE 1.
- the fabric according to the invention TISSU 2 has mechanical strength properties much higher than those of the fabric according to the prior art TISSU 0 not including aromatic polyester yarn.

- TISSU 4 therefore makes it possible to ensure the stability of the mechanical performance of the garments throughout their lifespan.
- Nomex® N302 yarns which form the face of FABRIC 4 are in the form of fiber yarns.
- the “Vectran ® ” yarns, which form the back, are in the form of continuous filaments.
- the weaving weave of FABRIC 4 makes it possible to balance the potential differential shrinkages which could appear after several washes, between the face made up of fiber yarns and the back made up of continuous filaments.
- the fabric has a very good appearance after washing and has a durability of its mechanical performance, even after a large number of washing cycles.
- the weaving weave used to make CLOTH 5 is shown on the Picture 7 , according to a diagram of the same type as in Figure 1 .
- the yarns 13 of “Vectran ® ” with a count of 220 dtex are present in the weave of the warp fabric and the yarns 14 of “Vectran ® ” with a count of 440 dtex are present in the weft.
- the “ Nomex® N302” yarns 15 are present in the weave both as warp yarns and as weft yarns.
- This weaving weave means that the "Vectran ® " yarns 13 with a count of 220 dtex, which are present in the weave of the warp fabric, are linked to the "Nomex ® N302" yarns 15 by binding points which are present in the middle of the fabric and/or on the back, but which are absent on the front. Furthermore, the “ Vectran® ” yarns 14 with a count of 440 dtex, which are present in the weft, are not linked to the “ Nomex® N302” yarns in the face.
- FABRIC 5 has a surface weight of 240 g/m 2 .
- FABRIC 5 The mechanical strength and fire resistance properties of FABRIC 5 were compared to those of the fabric of the prior art described in EXAMPLE 1, namely FABRIC 0. The tests of the present example were carried out according to the same protocols than those of EXAMPLE 1.
- the mechanical resistances in warp and weft of FABRIC 5 are particularly higher than those of FABRIC 0. Furthermore, the tear resistance in weft for FABRIC 5 is practically 3 times higher than that of TISSUE 0.
