• the present invention relates to the field of textiles used for the manufacture of fireproof and heat resistant clothing. It relates more specifically to textiles obtained from fibers known to have good properties of resistance to heat and / or flame. It relates more particularly to textiles obtained by the intimate bonding of two textile layers of distinct compositions having complementary properties. Such intimate binding of the two layers is generally achieved by means of warp or weft threads of one of the layers punctually making a binding loop around a warp or weft thread of the other layer of the textile.
• textile materials sold in the form of fibers or multi-filaments with very high mechanical and / or thermal performance but which have major disadvantages when used on the outer face of clothing. We speak here of deterioration of the performances with the radiations notably UV or of deterioration of aspect with the use and the washings notably by fibrillation.

• One of the objectives of the invention is to modify such an arrangement so as to make it possible to produce a double-layer textile, one of the layers of which is substantially closed, thereby guaranteeing good protection against the external aggressions of the textile thus formed, and in particular a good protection. to projections of chemicals in particular.
• Another objective is to produce a double-layer textile whose face has a good textile behavior, that is to say optimum characteristics of resistance to abrasion, pilling, fibrillation and coloristic and mechanical resistance, radiation including UV, while retaining good textile properties and a color suitable for use.

According to this test, after applying the flame, the fabric must not show flame spread, inflamed debris, hole formation and flame persistence longer than 2 seconds.
• the invention therefore relates to a double-layer textile having a first flame retardant layer having good abrasion resistance, pilling and lubrication, a color suitable for use.

• This textile comprises a second layer formed on the one hand in a material having high mechanical and / or thermal performance and obtained by warp and weft weaving of yarns of a second composition distinct from the first composition, and other part of a third composition which is punctually linked with the son of the first layer to allow to intimately join together the first and second layers of the textile.
• Such a double-layered textile thus has a face that is easy to decline at the coloristic level in particular and a reverse side comprising a material with high mechanical performance and advantageously thermal.
• the material having high mechanical and / or thermal performance is present exclusively on one and only one layer, and more precisely the back side.
• the number of threads per centimeter arranged in warp and / or weft of the first layer is greater than the number of threads per centimeter arranged in warp and / or weft of the second layer.

• the first composition of the son forming the first layer has good flame and heat resistance properties, making it possible to use such a textile under extreme conditions, and in particular to allow the production of clothing of people who may have to fight against fires, such as firefighters.
• the choice of materials constituting this first composition allows the latter to obtain optimum characteristics of resistance to abrasion, pilling, fibrillation and coloristic and mechanical resistance to UV radiation, while retaining good textile properties and coloring suitable for use.
• the son arranged in warp and weft of the first layer may be of the same nature.
• the face of the double-layered textile has a visual uniformity in terms of appearance and / or color.
• the second composition, present on the inner surface only may be chosen from the group comprising the fibers of para-aramid, polybenzimidazole, poly (p-phenylene-2,6-benzobisoxazole) and the mixtures obtained from these fibers.
• the son of the inner layer are partly made of a material that guarantees excellent thermal properties including heat resistance and / or excellent mechanical performance.
• the son forming the second layer may have low resistance to radiation including UV and / or washing, they are indeed protected and made invisible by the tight weaving son constituting the first layer.
• the third composition may be chosen from the group comprising meta-aramid fibers, polyamide-imide fibers, modacrylic fibers, flame retarded or non-flame-resistant cellulosic fibers, polyester or flame-retarded polyamide fibers, and blends obtained from of these fibers
• the warp son of the second layer may be different in nature from the weft son of the second layer.
• the weft yarns and the warp yarns constituting the second layer may be of a different nature. They can also include aspects and / or colors distinct from each other. Such an embodiment is however not troublesome because these son are invisible at the face of the double-layer textile.
