MATIERE FIBREUSE A BASE DE FIBRES D'ARAMIDE A RESISTANCE AMELIOREE  FIBROUS MATERIAL BASED ON IMPROVED RESISTANCE ARAMIDE FIBERS

La présente invention concerne une matière fibreuse à base de  The present invention relates to a fibrous material based on

fibres d'aramide, à résistance améliorée.  aramid fibers, improved strength.

Les fibres d'aramide sont des fibres à base de polyamide aromatique qui sont très utilisées dans les domaines techniques o l'on  Aramid fibers are aromatic polyamide-based fibers which are widely used in technical fields where

recherche des performances mécaniques et thermiques élevées.  looking for high mechanical and thermal performance.

Un emploi tout indiqué pour ces fibres est le domaine des  A perfect job for these fibers is the field of

vêtements de protection contre les agressions thermiques.  protective clothing against thermal aggressions.

Or, on sait que l'ensemble des fibres aramides peut être classé en deux catégories: - les fibres dites haut module, à hautes performances mécaniques et thermiques; - les fibres dites bas module, présentant de bonnes performances 15 thermiques et bénéficiant d'un excellent toucher textile; malheureusement, leur résistance mécanique est faible, et elles présentent, de plus, une  However, it is known that all aramid fibers can be classified into two categories: high modulus fibers, with high mechanical and thermal performance; the so-called low modulus fibers, having good thermal performances and benefiting from an excellent textile feel; unfortunately, their mechanical strength is low, and they have, moreover, a

mauvaise résistance à l'abrasion.poor resistance to abrasion.

Les fibres dites de haut module sembleraient donc plus désignées pour la réalisation de vêtements de protection; malheureusement, quand 20 elles sont employées seules, elles ne permettent pas d'obtenir un confort au  So-called high modulus fibers would seem more suitable for the realization of protective clothing; unfortunately, when they are used alone, they do not make it possible to

porter satisfaisant; d'autre part, elles ne présentent pas d'affinité pour les colorants et, de ce fait, leur aspect ne peut être modifié par teinture.  wear satisfying; on the other hand, they do not have an affinity for the dyes and, therefore, their appearance can not be modified by dyeing.

La Demanderesse a découvert qu'il était possible de renforcer, de façon spectaculaire, les propriétés mécaniques des filés de fibres d'aramide 25 bas module, si on leur adjoignait une quantité relativement faible, se situant au-dessus de 20 % et, de préférence, entre 20 et 25 %, de fibres d'aramide  Applicants have discovered that it is possible to dramatically increase the mechanical properties of low modulus aramid fiber yarns by adding a relatively small amount, above 20%, and preferably between 20 and 25% of aramid fibers

haut module.high module.

L'augmentation de la résistance des filés obtenus à partir de ce mélange de fibres est tout à fait surprenante, puisqu'elle atteint et dépasse 30 même 40 % par rapport à la résistance des filés de fibres aramide bas  The increase in the strength of yarns obtained from this blend of fibers is quite surprising, since it reaches and even exceeds 40% of the strength of low aramid fiber yarns.

module employés seuls.module alone.

Selon un autre mode de réalisation de l'invention, on remplace une  According to another embodiment of the invention, one replaces a

partie des fibres aramide bas module par des fibres de viscose dite "viscose non feu", ce qui élargit encore le domaine d'application du mélange selon 35 l'invention aux vêtements de protection contre les agressions thermiques.  part of the low aramid fibers modulus by viscose fibers called "viscose not fire", which further widens the range of application of the mixture according to the invention protective clothing against thermal attack.

La matière fibreuse comporte environ 47 % de fibres d'aramide bas module, environ 30 % de fibres de viscose non feu et environ 23% de  The fibrous material comprises about 47% low modulus aramid fibers, about 30% nonfire viscose fibers and about 23%

fibres d'aramide haut module.high modulus aramid fibers.

Les fibres d'aramide, qu'il s'agisse de fibres d'aramide haut module ou de fibres d'aramide bas module, sont avantageusement obtenues par craquage de filaments à une hauteur moyenne de 110 mm. 5 Cette transformation des filaments continus s'effectue selon un procédé de craquage par étirage et rupture contrôlée; elle est effectuée sur des câbles de multifilaments de fibres unitaires, dont le titre se situe entre 0,8 et 6 dtex. On obtient ainsi des fibres longues, ce qui permet de filer une très large gamme de titres entre 1/1 (1000lQOtex) et 200/1 (5tex). 10 Le mélange intime des fibres ainsi obtenues, auxquelles on rajoute  The aramid fibers, whether they are high modulus aramid fibers or low modulus aramid fibers, are advantageously obtained by cracking filaments at an average height of 110 mm. This transformation of the continuous filaments is carried out according to a process of cracking by stretching and controlled breaking; it is performed on multifilament cables of unitary fibers, whose title is between 0.8 and 6 dtex. Long fibers are thus obtained, which makes it possible to spin a very wide range of titles between 1/1 (1000lQOtex) and 200/1 (5tex). 10 The intimate mixture of the fibers thus obtained, to which we add

éventuellement la viscose non feu sous forme de fibres coupées de 80 mm, s'effectue par tout procédé connu en soi, en amont de la préparation.  optionally the non-fire viscose in the form of cut fibers of 80 mm, is carried out by any method known per se, upstream of the preparation.

Les opérations complémentaires de finition, telles que le retordage  Complementary finishing operations, such as twisting

ou le câblage, sont ensuite effectuées sur les produits obtenus.  or cabling, are then performed on the products obtained.

On dispose ainsi d'une matière fibreuse extrêmement intéressante, puisqu'elle présente les principaux avantages des fibres d'aramide bas module, parmi lesquels on peut citer le confort au porter et l'aptitude à la teinture, des propriétés de résistance améliorée, et ceci tout en conservant les excellentes propriétés de résistance aux expositions thermiques, ainsi 20 qu'à certains produits chimiques, ce qui la rend tout à fait adaptée à la  There is thus a fibrous material extremely interesting, since it has the main advantages of low modulus aramid fibers, among which include wear comfort and dyeability, improved strength properties, and this while retaining the excellent thermal exposure resistance properties as well as certain chemical products, which makes it quite suitable for

réalisation de vêtements de protection contre les agressions thermiques.  production of protective clothing against thermal aggressions.
