Definitions

• the present invention relates to a thermal protection fabric, in particular a fabric which can be used for the production of clothing used by the fire brigade.
• An intervention textile jacket generally comprises an outer layer consisting of an aramid fabric or equivalent, a sealing barrier laminated on a non-fire felt, an insulation system consisting of a knitted fabric or an aramid felt or equivalent and an inner lining.
• Such a jacket has a number of disadvantages in use.
• Such a jacket is very heavy, and poses problems of ergonomics and ease of wearing due to the stacking of several layers. Finally, such a jacket is difficult to maintain, and can present appearance problems after washing.
• para-aramid multifilaments are very sensitive to hydrolysis. They can not withstand the washing conditions in an aqueous medium, they therefore quickly lose their mechanical performance, and become more sensitive to abrasion, thereby causing fibrillation. which is a deterioration of the thread resulting in the appearance of a whitish pollution on the fabric.
• Para-aramid multifilaments are sensitive to ultraviolet radiation and to part of the visible spectrum, for wavelengths between 300 and 450 nm, in the presence of which they fairly quickly lose their original mechanical properties.
• the object of the invention is to provide a thermal protection fabric having good qualities of thermal protection and mechanical protection, resistant to washing well and having a good surface appearance after washing, resistant to radiation, such as ultraviolet rays. , and offering a satin or shiny surface appearance making it possible to identify the wearer of a garment produced using such a fabric in poor visibility conditions, in particular during intervention in a smoky area.
• the thermal protection fabric which it concerns, comprising a weave of warp threads in one direction and of weft threads in the perpendicular direction, is characterized in that it comprises, in one direction, threads made up alternating continuous filaments and spun fibers, and in the other direction, threads made from spun fibers, the various continuous filaments and spun fibers being made of non-flammable and non-fusible materials.
• the continuous filaments are made of meta-aramid, as known under the brand Nomex,
• the yarns of fibers associated alternately with the continuous filaments are made of meta-aramid, as known under the brand
• the yarns formed by yarns of fibers in the other direction include meta-aramid fibers, as known under the brand Nomex and para-aramid fibers, as known under the brand Keviar.
• the combination of continuous filaments and fiber yarns in one direction of the fabric with fiber yarns in the other direction provides very good thermal protection, while providing the fabric with excellent mechanical properties.
• the para-aramid fibers are arranged in a core and the meta-aramid fibers are arranged in cover.
• the yarns are produced from yarns of fibers comprising approximately 1/3 of para-aramid fibers and 2/3 of meta-aramid fibers.
• the different threads in the two directions are combined so as to form a complex double-faced weave of satin type, such that the outer face of the fabric is composed essentially of continuous filaments and the inner face is mainly composed of fiber yarns.
• the surface thus formed has a very shiny appearance compared to that obtained with fiber yarns, this effect giving rise to excellent reflection by radiant heat.
• this shiny surface allows the wearer of the garment to be easily identified in the middle of smoke, fire or in the dark, since the continuous filaments reflect light, unlike the traditional outer layers which remain dull.
• this smooth outer layer improves ease of wearing by reducing the friction of the different parts of the jacket during movements relative to each other.
• the maintenance of the garment is facilitated, since during its use, the outer layer does not form a gripping surface, the dust and debris not coming not stick to this surface.
• the yarns of fibers dispersed among the continuous filaments in one direction bind to the yarns in the other direction on the rear face of the fabric, and they are more important than the continuous filaments.
• the yarns of fibers present on the rear face of the fabric have a higher count than the continuous filaments, they provide a relief effect with the formation of thickeners which, once in contact with the second layer of the textile complex, delimit an air space which contributes to the thermal insulation of the garment.
• the threads in one direction, are constituted by an alternation of continuous filaments and yarns of fibers in proportions of 5 to 1.
• Electrostatic properties can be obtained in this type of fabric by a combination of dissipative or electrostatic wires or fibers in either direction.
• This fabric comprises warp threads made up of continuous filaments of meta-aramid, of Nomex type, of 220 dtex title and of threads of meta-aramid fibers, of Nomex type of title Nm 60/2 in the proportion of 5 to 1. , and weft yarns made of spun fibers of Nm 55/2 titer made using the core yarn technique, composed of around 33% pararamid fibers of the Keviar type in the core and 67% meta fibers Nomex type aramid on the cover, the weave being of the satin type with the filaments on the right side, while the fiber yarns mainly appear on the reverse side where they are linked with the weft threads to form a reinforcement grid, the fabric possibly undergoing a waterproofing type finishing treatment making it possible to provide characteristics of repellency.
• this fabric can be combined with an intermediate layer constituted by a membrane laminated on a felt and an inner layer constituted by a lining.
