Abstract
Description
La presente invention se referme aux feuilles propres à former enveloppes étanches aux liquides, mais à se dégrader progressivement par la suite au sein du milieu dans lequel elles ont été placées avec leur contenu, de manière à pleinement exposer celui- ci à l'action de ce milieu. Un exemple typique d'application de telles feuilles est la réalisation de linceuls ou housses d'inhumation qui doivent assurer d'etanchéité autour du corps pendant un temps suffisant, puis se dégrader à la longue afin que le corps puisse subir les phénomènes naturels de décomposition.Mais l'invention n'est pas limitée à ce domaine particulier et lton peut la mettre en oeuvre dans tous les cas posant des problèmes analogues, notamment quand on veut disposer de déchets organiques (ordures ménagères, débris de végétaux, etc...). The present invention closes with the sheets suitable for forming liquid-tight envelopes, but for gradually degrading thereafter within the medium in which they have been placed with their contents, so as to fully expose the latter to the action of this medium. A typical example of application of such sheets is the production of shrouds or burial covers which must ensure sealing around the body for a sufficient time, then degrade over time so that the body can undergo the natural phenomena of decomposition. .But the invention is not limited to this particular field and can be used in all cases posing similar problems, in particular when it is desired to dispose of organic waste (household waste, plant debris, etc.). ).
L'invention vise à résoudre ce problème de façon particulièrement simple, fiable et peu coûteuse. The invention aims to solve this problem in a particularly simple, reliable and inexpensive manner.
Conformément à l'invention l'on établit la feuille à l'aide d'un support non étanche qu'on enduit ou imprègne d'un agent d'étanchéité auto-destructible, notamment bio-degradable. In accordance with the invention, the sheet is established using a non-waterproof support which is coated or impregnated with a self-destructing sealing agent, in particular bio-degradable.
On comprend que dans ces conditions la feuille est initialement étanche et peut plus particulièrement servir notamment de housse autour d'un corps à inhumer en empêehant toute sortie de liquide (les gaz pouvant en général s'échapper à travers des filtres appropries judicieusement disposés). Puis avec le temps l'agent d'étancheité se detruit et le support ne forme plus cloison s'opposant à la decomposition normale du corps. It is understood that under these conditions the sheet is initially waterproof and can more particularly serve in particular as a cover around a body to be buried by preventing any outflow of liquid (the gases generally being able to escape through suitably disposed filters). Then over time the sealant is destroyed and the support no longer forms a partition opposing normal decomposition of the body.
L'on établit préfErablement le support à l'aide de fibres textiles non tissées disposées sous la forme d'une nappe que l'enduction ou imprégnation par l'agent d'étanchéité transforme en feuille continue. The support is preferably established using non-woven textile fibers arranged in the form of a sheet which the coating or impregnation with the sealing agent transforms into a continuous sheet.
Cette disposition pressente l'avantage que lorsque cet agent s'est détruit, le support lui-meme se désagrège et disparaît plus ou moins complètement. Les fibres mises en oeuvre peuvent entre de tout genre, naturelles ou synthétiques, étant note que les premières sont souvent bio-dégradables, ce qui constitue un avantage pour le résultat recherché.This arrangement has the advantage that when this agent is destroyed, the support itself disintegrates and disappears more or less completely. The fibers used can be of any kind, natural or synthetic, it being noted that the former are often biodegradable, which constitutes an advantage for the desired result.
On peut encore utiliser avantageusement des mélanges des deux genres de fibres, par exemple 70 % de fibres cellulosiques et 30 % de fibres acryliques.It is also advantageous to use mixtures of the two kinds of fibers, for example 70% of cellulose fibers and 30% of acrylic fibers.
En variante on peut réaliser le support à l'aide de papier, préférablement de papier poreux propre à mieux absorber l'agent d'étanchéité. On sait que de tels papiers se dégradent assez facilement dans le sol et sous l'effet de l'humidité, de sorte que là encore le support disparatt après destruction de l'agent d'étanchéité qui le protégeait. As a variant, the support can be produced using paper, preferably porous paper capable of better absorbing the sealing agent. It is known that such papers degrade quite easily in the soil and under the effect of humidity, so that again the support disappears after destruction of the sealing agent which protected it.
Conformément à une autre caractéristique de l'invention l'on utilise en guise d'agent d'étanchéité un collagène et l'on soumet le support imprégné d'un tel agent à une opération de tannage de manière à durcir l'agent et à ralentir son processus d'auto-destruction ou bio-dégradation au contact du sol. Les collagènes ainsi tannés assurent à la feuille une bonne tenue au point de vue de la résistance et de l'indéformabilité.En prévision de la nécessité de plier la feuille ainsi obtenue pour tapisser sar exemple les parois d'un cercueil sans provoquer des fissures ou craquelures nuisibles à l'étanchéité, on mélange avantageusement au collagène une quantité suffisante d'un plastifiant approprié, tel par exemple que le sulforicinate d'ammoniub Les essais ont démontré que les collagènes ainsi traités présentent des qualités de souplesse et de solidité qui en facilitent, en même temps qu'ils permettent plus particulièrement de réaliser le support à l'aide de nappes de fibres sans que la feuille finalement obtenue s'avère excessivement déchirable. In accordance with another characteristic of the invention, collagen is used as a sealing agent and the support impregnated with such a agent is subjected to a tanning operation so as to harden the agent and slow down its process of self-destruction or bio-degradation in contact with the ground. The collagen thus tanned ensures good resistance to the sheet in terms of strength and non-deformability. In anticipation of the need to fold the sheet thus obtained to line the walls of a coffin, for example, without causing cracks or cracking detrimental to sealing, advantageously a sufficient quantity of a suitable plasticizer is mixed with collagen, for example such as ammonium sulforicinate. Tests have demonstrated that the collagens thus treated have qualities of flexibility and solidity which facilitate them. , at the same time as they make it possible more particularly to produce the support using sheets of fibers without the sheet finally obtained proving excessively tearable.
Avant l'imprégnation ou enduction au collagène il est possible de procéder à une sorte de pré-encollage à l'aide d'un agent tel que l'alcool polyvinilique, qui assemble les fibres sans toutefois imperméabiliser leur ensemble. Before impregnation or coating with collagen, it is possible to carry out a kind of pre-sizing using an agent such as polyvinyl alcohol, which assembles the fibers without, however, waterproofing them as a whole.
De quelque manière qu'on procède, on obtient finalement une feuille souple parfaitement étanche, qui se prête bien aux applications précitées, notamment pour envelopper les corps à inhumer, puis qui s'auto-détruit ensuite dans le sol en permettant la décomposition naturelle de son contenu. However one proceeds, one obtains finally a perfectly waterproof flexible sheet, which lends itself well to the aforementioned applications, in particular for enveloping the bodies to be buried, then which self-destructs then in the ground by allowing the natural decomposition of its content.
Il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents. It should moreover be understood that the above description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
