Description

La présente invention se rapporte à un procédé permettant d'obtenir des matières textiles indécelables aux rayonnements infrarouges.The present invention relates to a method for obtaining textile materials which cannot be detected by infrared radiation.

Le procédé suivant l'invention permet d'obtenir des textiles qui, soumis à une détection par rayonnements infrarouges, soit grâce à la photographie, soit par des appareils optiques électroniques de détection, absorbent ces rayonnements, ce qui les rend invisibles à ces procédés de détection.The method according to the invention makes it possible to obtain textiles which, subjected to detection by infrared radiation, either by photography or by electronic detection optical devices, absorb these radiation, which makes them invisible to these methods of detection.

Son application la plus importante se fait dans des articles destinés à des fins militaires, puisqu'elle y est particulièrement essentielle et s'utilise fréquemment pour ses propriétés de camouflage.Its most important application is in articles intended for military purposes, since it is particularly essential and is frequently used for its camouflage properties.

Actuellement, on connaît seulement deux procédés pour lesquels on possède des informations dans le domaine textile, l'un venu des Etats-Unis d'Amérique et l'autre de France, que l'on met en oeuvre grâce à l'incorporation de noir de fumée dans les pâtes prévues pour la préparation du filament de polyester, qui, par la suite, est transformé en fibre prête à une utilisation textile.Currently, only two processes are known for which there is information in the textile field, one from the United States of America and the other from France, which is implemented thanks to the incorporation of black. smoke in the doughs intended for the preparation of the polyester filament, which is subsequently transformed into fiber ready for textile use.

Le procédé faisant l'objet de la présente invention permet l'incorporation de noir de fumée à n'importe quelle classe de fibres textiles, qu'elles soient naturelles, synthétiques ou artificielles, dans n'importe quelle phase de leur élaboration textile, à savoir floc, peigné, fil ou tissu, indépendamment de la couleur, de la texture de l'armure ou du mélange de fibres entre elles. D'une manière générale, le procédé se base sur l'obtention de noir de fumée en dispersion dans des résines d'apprêt textile, en modifiant cet apprêt ou non, de manière que, par la suite, à l'incorporation dans un bain aqueux, on maintienne les particules de noir de fumée à l'état finement dispersé. De la sorte, après obtention de la solution aqueuse et avec les particules à l'état dispersé, on peut les déposer sur le substrat textile grâce à un procédé d'imprégnation et d'essorage avec séchage et polymérisation ultérieure ou par épuisement, grâce à l'hydrolyse du bain en pH légèrement acide.The process which is the subject of the present invention allows the incorporation of smoke black into any class of textile fibers, whether natural, synthetic or artificial, in any phase of their textile production, namely flock, combed, thread or fabric, regardless of the color, the texture of the weave or the mixture of fibers between them. In general, the process is based on obtaining smoke black in dispersion in textile finishing resins, modifying this finishing or not, so that, subsequently, when incorporated into a bath aqueous, the particles of smoke black are kept in the finely dispersed state. In this way, after obtaining the solu tion with the particles in the dispersed state, they can be deposited on the textile substrate by means of an impregnation and wringing process with drying and subsequent polymerization or by exhaustion, thanks to the hydrolysis of the bath in pH slightly acid.

La nouveauté apportée par ce procédé est manifeste, puisque, jusqu'à présent, c'est la première fois que l'utilisation du noir de fumée dans le domaine textile, non pas dans la fabrication des fibres, se fait à des fins de camouflage.The novelty brought by this process is obvious, since, until now, it is the first time that the use of smoke black in the textile field, not in the manufacture of fibers, is done for camouflage purposes. .

D'autre part, on peut déposer le noir de fumée, ce qui constitue un perfectionnement nouveau, sur une fibre textile quelconque en milieu aqueux, tel que celui traditionnellement utilisé dans l'industrie textile pour la transformation et l'apprêt des textiles.On the other hand, the smoke black can be deposited, which constitutes a new improvement, on any textile fiber in an aqueous medium, such as that traditionally used in the textile industry for the transformation and finishing of textiles.

Le noir de fumée est insoluble et, avec ce procédé, on obtient des dispersions aqueuses stables permettant leur utilisation industrielle. Il est en outre à signaler que le noir de fumée déposé en poussière dans les textiles n'élèvera pas les résistances ou solidités aux exigences permettant de satisfaire à la plupart des normes textiles DIN ou ISO, et communément acceptées dans le domaine textile, telles que les réssistances aux frottements, aux nettoyages à sec et aux lavages, et d'autres normes spécifiquement industrielles auxquelles les textiles sont soumis durant leur processus d'élaboration en tissus. Avec le procédé suivant la présente invention, la résine permet non seulement d'obtenir une dispersion d'une utilisation industrielle facile, mais en outre, après le séchage et la polymérisation, elle assure la fonction d'agent réticulant qui fait adhérer les particules aux textiles et les recouvre sous forme d'une pellicule très fine en leur donnant les mêmes résistances ou solidités que celles présentées par la résine, vis-à-vis des exigences particulières que doivent présenter les textiles, ce qui s'obtient avec une ou plusieurs résines d'apprêt textile, suivant le type de fini que demande le textile, selon la phase d'élaboration en cause ou selon ce qu'il faut atteindre en définitive.The smoke black is insoluble and, with this process, stable aqueous dispersions are obtained allowing their industrial use. It should also be noted that the black smoke deposited in dust in textiles will not raise the strengths or solidities to the requirements making it possible to satisfy most of the textile standards DIN or ISO, and commonly accepted in the textile field, such as resistance to friction, dry cleaning and washing, and other specifically industrial standards to which textiles are subjected during their fabric development process. With the process according to the present invention, the resin not only makes it possible to obtain a dispersion of easy industrial use, but also, after drying and polymerization, it performs the function of crosslinking agent which makes the particles adhere to the textiles and covers them in the form of a very thin film, giving them the same strengths or solidities as those presented by the resin, with regard to the specific requirements that textiles must have, which is obtained with one or more textile finishing resins, depending on the type of finish required by the textile, depending on the production phase in question or according to what must ultimately be achieved.

Une autre nouveauté importante de l'invention est la possibilité de pratiquer des dépôts de quantités en pourcentages divers sur le textile, suivant les degrés d'immunité aux détections par une lumière infrarouge, sans que le tissu ne soit altéré de façon substantielle, ni au toucher ni en ce qui concerne la couleur à un degré appréciable.Another important novelty of the invention is the possibility of practicing deposits of quantities in various percentages on the textile, according to the degrees of immunity to detections. infrared light, without the fabric being substantially altered, neither to the touch nor to the color to an appreciable degree.

Avec le procédé suivant l'invention, on obtient des tissus ou des textiles dans un état quelconque d'élaboration, qui, soumis à un éclairement ou à l'action de sources lumineuses ou infrarouges, plus particulièrement dans le rouge extrême, c'est-à-dire supérieures à environ 700 nanomètres, absorbent ces rayonnements sans être détectés par les moyens que l'on utilise habituellement pour une telle détection, par exemple avec les pellicules photographiques pour infrarouge en blanc et noir et les pellicules en couleurs, dont la détection maximale est proche d'envirion 1200 nanomètres, ce qui équivaut à une zone de sensibilisation comprise entre 6500 0 et 8500 A. La même chose se produit avec les appareils qui combinent l'optique et l'électronique pour rendre ces rayonnements visibles à la simple vue.With the process according to the invention, fabrics or textiles are obtained in any state of development, which, subjected to lighting or to the action of light or infrared sources, more particularly in extreme red, is that is to say greater than about 700 nanometers, absorb these radiations without being detected by the means that are usually used for such detection, for example with photographic films for infrared in black and white and color films, the maximum detection is close to around 1200 nanometers, which is equivalent to an awareness zone of between 6500 0 and 8500 A. The same thing happens with devices that combine optics and electronics to make these rays visible to the simple sight.

Le procédé suivant l'invention est, d'une manière générale, le suivant.The process according to the invention is, in general, the following.

On emploie du noir de fumée d'une variété très pure de carbone amorphe, d'une composition comportant 98-99% de carbone et 2 à 3% d'hydrogène. Ce noir de fumée s'obtient par une combustion convenablement réglée avec des quantités limitées d'air, d'huiles grasses, de goudrons, de pétrole, de térébenthine,etc., suivant ce qui peut convenir d'après ce qui existe sur le marché.Smoke black is used from a very pure variety of amorphous carbon, a composition comprising 98-99% carbon and 2 to 3% hydrogen. This black smoke is obtained by a suitably regulated combustion with limited quantities of air, fatty oils, tars, petroleum, turpentine, etc., according to what may be suitable according to what exists on the market.

Le noir de fumée en poudre ainsi obtenu est insoluble en milieu aqueux, de sorte qu'il est difficile de l'appliquer dans l'industrie textile et, pour éviter cet inconvénient, on suit le procédé exposé ci-après : on forme une pâte avec une résine concentrée jusqu'à l'obtention d'une dispersion homogène et stable, en se servant à cette fin des dispersants et des émulsionnants que comportent les résines sous une forme commerciale.The powdered smoke black thus obtained is insoluble in an aqueous medium, so that it is difficult to apply it in the textile industry and, to avoid this drawback, the process described below is followed: a paste is formed with a concentrated resin until a homogeneous and stable dispersion is obtained, using for this purpose the dispersants and emulsifiers which the resins contain in a commercial form.

Après cette phase de mise en pâte, on procède à la dissolution dans une solution aqueuse de la résine employée pour la mise en pâte, grâce à une agitation continue, jusqu'à son emploi comme apprêt.After this phase of pulping, the resin used for pulping is dissolved in an aqueous solution, by continuous stirring, until it is used as a primer.

L'imprégnation du textile se fait par le procédéd de foulardage et d'essorage, ou par épuisement, comme on l'expliquera en détail par la suite . Ensuite, on procède au séchage, à une température qui doit être comprise entre 50 et 90°C suivant le textile que l'on traite.The impregnation of the textile is done by the process of padding and wringing, or by exhaustion, as will be explained in detail below. Then, drying is carried out, at a temperature which must be between 50 and 90 ° C. depending on the textile which is being treated.

Enfin, on procède à la polymérisation dont l'opération doit être réalisée suivant les résines employées comme support pour le noir de fumée, mais qui, d'une façon générale, devra se faire à 130-140°C et sur une période de 3 à 5 minutes. Le séchage et la polymérisation sont tous deux communs à tous les procédés que l'on décrira. Résines à employer: l'emploi des résines assure une double fonction: d'une part, il permet la dispersion ou l'émulsion, suivant le cas, de la poudre de noir de fumée, ce qui permet de l'appliquer de manière industrielle avec l'outillage traditionnel employé dans l'industrie textile. D'autre part, ces résines constituent un réticulant approprié pour obtenir les résistances suivantes exigées pour des pièces et des matières textiles d'un usage courant :

  • solidité à la lumière 6-7
  • résistance au lavage à 30° 4-5
  • résistance à l'eau 5
  • résistance aux transpirations
  • alcalines 4
  • résistance aux transpirations
  • acides 4
  • solidité à la chaleur 180° 4-5
Finally, the polymerization is carried out, the operation of which must be carried out according to the resins used as a support for the smoke black, but which, in general, must be carried out at 130-140 ° C. and over a period of 3 5 minutes. Drying and polymerization are both common to all the processes which will be described. Resins to be used: the use of resins ensures a double function: on the one hand, it allows the dispersion or the emulsion, as the case may be, of the powder of black smoke, which makes it possible to apply it industrially with the traditional tools used in the textile industry. On the other hand, these resins constitute an appropriate crosslinking agent to obtain the following resistances required for parts and textile materials of common use:
  • light fastness 6-7
  • resistance to washing at 30 ° 4-5
  • water resistance 5
  • resistance to perspiration
  • alkaline 4
  • resistance to perspiration
  • acids 4
  • heat fastness 180 ° 4-5

Résines - Le choix des résines d'apprêt à utiliser comme diluants et supports du noir de fumée dépendra du fini que l'on désire obtenir, en tenant compte que doivent être satisfaites les exigences de chaque cas, déterminées par les divers types de textiles ou de tissus suivant le cas, qu'il s'agisse de vêtements, de fils pour travaux, de pièces de protection, de gabardines, etc. Après de très nombreux essais, on a obtenu les meilleurs résultats avec les résines et les concentrations de noir de fumée que l'on détaille ci-après.Resins - The choice of primer resins to be used as thinners and supports for smoke black will depend on the finish desired, taking into account that the requirements of each case must be satisfied, determined by the various types of textiles or fabrics as appropriate, whether clothing, yarn for work, protective parts, gabardines, etc. After numerous tests, the best results have been obtained with the resins and the concentrations of smoke black which are detailed below.

Tous les essais réalisés et à réaliser ont pour but l'incorporation de noir de fumée dans les textiles, avec des garanties de résistance ou solidité et d'application facile, comme on en n'a jamais employé jusqu'à présent dans l'industrie textile afin d'obtenir des textiles qui absorbent les rayonnements infrarouges au-dessus des 700 nanomètres, raison pour laquelle ces textiles sont faciles à camoufler aux détections faites grâce à des photographies avec des pellicules sensibles à l'infrarouge, de haute rapidité, d'un type quelconque, tout en empêchant aussi la détection par des appareils du type télescope infrarouge, une combinaison optique et électronique dans une gamme comprise entre 600 et 1250 nanomètres, et on obtient également une zone de tolérance obtenue avec le spectre de Beckman.All the tests carried out and to be carried out aim at incorporating smoke black in textiles, with guarantees of resistance or solidity and easy to apply, as has never been used in the industry until now. textile in order to obtain textiles which absorb infrared radiation above 700 nanometers, which is why these textiles are easy to camouflage with the detections made thanks to photographs with infrared-sensitive films, of high speed, of any type, while also preventing detection by apparatuses of the infrared telescope type, an optical and electronic combination in a range between 600 and 1250 nanometers, and a tolerance zone obtained with the Beckman spectrum is also obtained.
