Problems solved by technology

Although they are mechanically pleasing, para-aramid fibers have the disadvantage of discoloration during use and washing and thus become more visible over time; this phenomenon (known as fibrillation) is not too beautiful

example 1

[0041] According to this example, a textile having two layers may comprise a first layer, by using a weight of 165 g / m 2 The 2 / 1 twill fabric is formed by weaving by changing the organization. The density of the warp threads of this first layer may be 32.4 threads per centimeter and the density of the weft threads may be equal to 22.5 threads per centimeter. Said first layer is advantageously constituted only in the warp and weft direction by the same yarn comprising 93% fully dyed meta-aramid fibers, 5% fully dyed para-aramid fibers and 2% antistatic fiber. Such yarns can be produced by combining several spun yarns of fibers which are joined or combined in a twisting manner. Advantageously, said yarn may consist of two spun yarns of metric count 70. Such yarns can therefore be characterized by a metric count Mc of a value of 70 / 2 (ie, 285 decitex).

[0042] According to this example, the second layer can be obtained by using a weight of 85g / m 2 The canvas weave is formed...

example 2

[0059] According to this example, a textile with two layers may comprise a first layer by using a weight of 195 g / m 2 2 / 1 twill fabric to weave and form. The density of warp threads of this first layer may be 35.3 threads per centimeter and the density of weft threads may be equal to 21.0 threads per centimeter. Said first layer is advantageously composed only of the same yarns in the warp and weft directions, comprising 60% modacrylic fibers and 40% cotton fibers. Such yarns can be produced by combining several individual spun yarns which are joined or combined in a twisting manner. Advantageously, the yarn may consist of two spun yarns of 60 metric count. This yarn is therefore characterized by a metric count Mc having a value of 60 / 2 (ie 333 decitex).

[0060] According to this example, the fabric forming the second layer can be obtained by using a weight of 55 g / m 2 The canvas weave is formed by weaving the fabric. The second layer may have a warp yarn density of 11.8...

Abstract

The invention relates to a fabric (1) for manufacturing garments for fire protection, comprising two woven layers, namely an outer layer (2), made up mainly of threads (6, 7) of a first type, and an inner layer (3), made up mainly of threads (8) of a second type different from the first type, wherein the threads (6, 7) of the first type have resistance to degradation, caused by wear and washing, of the appearance properties thereof which is greater than that of the threads (8) of the second type, and the threads of the second type have mechanical tearing strength properties which are greater than those of the threads of the first type, characterised in that the inner layer (3) comprises threads (9) of a third type which are different from the threads (8) of the second type, the threads of the third type having a resistance to the degradation, caused by wear and washing, of the appearance properties thereof which is greater than that of the threads (8) of the second type, said threads (9) of the third type also working with the outer surface in order to ensure the binding of the two layers (2, 3), and in that the number of threads per centimetre arranged in the warp and / or weft of the first layer is greater than the number of threads per centimetre arranged in the warp and / or weft of the second layer.

Description

technical field [0001] The present invention relates to the field of textiles for the manufacture of fire and heat resistant clothing. More particularly, the present invention relates to textiles obtained from fibers known to have good heat and / or flame retardant properties. More specifically, the invention is directed to textiles obtained by intimately combining two textile layers containing different compositions with complementary properties. Such intimate bonding of the two layers is generally performed using the warp or weft yarns of one of the two layers to periodically form bonding loops around the warp or weft yarns of the other layer of the textile fabric. Background technique [0002] There are textile materials for the production of outer layers of protective clothing which impart good abrasion resistance, pilling resistance, good color strength and mechanical resistance to radiation (especially UV) to the textile layer and which are suitable for its Use the col...
