D'autres caractéristiques et avantages de l'invention ressortiront de la description qui suit et qui est donnée à titre d'exemple sans caractère limitatif.Other characteristics and advantages of the invention will emerge from the description which follows and which is given by way of example without limitation.
Dans le cadre de la mise en oeuvre de la présente invention en vue de la réalisation du matériau complexe défini précédemment on utilise un non-tissé répondant aux caractéristiques ciaprès:
- Voie de fabrication : Spunlaced
- Nature des Fibres : Polyester
- Liant : Maximum 3 à 5 t
- Nature du Liant : Acrylique
- Grammage : 80 - 85 Grs M2
- élasticité : 150 (Norme ISO 5081)
- #ésistance Sens Machine : 30.In the context of the implementation of the present invention with a view to producing the complex material defined above, a nonwoven is used which meets the following characteristics:
- Manufacturing method: Spunlaced
- Nature of Fibers: Polyester

- Machine direction resistance: 30.
Sur cette première couche de départ on rapporte un film plastique répondant aux caractéristiques ci-après
- Film : Obtenu par extrusion
- Nature : Acrylique
- Grammage : 30 Grs. M2
- élasticité : 100 à 150 t
sans perdre ses propriétés
d'étanchéité
- Perméabilité à la : Norme ASTM E 96
Vapeur d'Eau 50 - 60 Grs. M2 par 24 heures. On this first starting layer, a plastic film corresponding to the characteristics below is added.
- Film: Obtained by extrusion
- Nature: Acrylic
- Weight: 30 Grs. M2
- elasticity: 100 to 150 t
without losing its properties
sealing
- Permeability to: ASTM E 96 standard
Water vapor 50 - 60 Grs. M2 per 24 hours.
Le film de résine acrylique est rapporté, au sortir de sa production par extrusion et à l'état encore plastique.The acrylic resin film is added, at the end of its production by extrusion and in the still plastic state.
Et les deux couches sont soumises à une opération de laminage par calandrage qui provoque une imbrication intime du film de résine acrylique dans la structure fibreuse du tissu non-tissé au contact de laquelle il est amené par le jeu des calandres coopérant entre elles.And the two layers are subjected to a calendering laminating operation which causes an intimate nesting of the acrylic resin film in the fibrous structure of the nonwoven fabric in contact with which it is brought by the play of the cooperating calenders.
On obtient ainsi un matériau complexe particulièrement intéressant pour ses perspectives d'applications dans le domaine hospitalier notamment en milieu stérile.A complex material is thus obtained which is particularly advantageous for its prospects for applications in the hospital sector, in particular in a sterile environment.
Le matériau est en effet remarquable par sa solidité, par sa souplesse et son élasticité.The material is indeed remarkable for its solidity, its flexibility and its elasticity.
La présence de la couche de résine acrylique lui confère une propriété d'imperméabilité totale aux liquides ; alors qu'il conserve une perméabilité aux gaz de 50 à 60 grammes par m2 et par 24 heures.The presence of the acrylic resin layer gives it a property of total impermeability to liquids; while it retains a gas permeability of 50 to 60 grams per m2 and per 24 hours.
Ce matériau convient donc pour tous les types d'interventions chirurgicales et garantit aux praticiens utilisateurs, grâce à sa parfaite imperméabilité, le maximum d'asepsie qu'ils sont en droit d'attendre tout en conservant les spécificités du matériau non-tissé de départ à savoir : la souplesse et l'extensibilité, permettant notamment un allongement allant jusqu'à 100 . This material is therefore suitable for all types of surgical procedures and guarantees to user practitioners, thanks to its perfect waterproofness, the maximum asepsis that they are entitled to expect while retaining the specificities of the starting nonwoven material. namely: flexibility and extensibility, allowing in particular an elongation of up to 100.
Le matériau ne peluche pas et ne présente donc pas de risque de relarguer dans l'atmosphère des poussières parasites.The material does not fluff and therefore does not present a risk of releasing parasitic dust into the atmosphere.
Sa résistance mécanique est considérable, le matériau répondant à la traction par des possibilités d'allongement, plus importantes dans le sens transversal du non-tissé en résistant toutefois aux déchirements ; le matériau présentant une extensibilité suffisante à la traction dans le sens longitudinal lui permettant de s'adapter, de se prêter de façon à répondre aux conditions d'utilisations notamment à titre de champs opératoires.Its mechanical resistance is considerable, the material responding to traction by possibilities of elongation, greater in the transverse direction of the non-woven fabric, however resisting tearing; the material having sufficient extensibility to traction in the longitudinal direction allowing it to adapt, to lend itself so as to meet the conditions of use, in particular as operating fields.
Il est entendu que le non tissé de départ qui représente une des couches du matériau complexe peut subir par ailleurs des traitements appropriés en fonction des besoins.It is understood that the starting nonwoven which represents one of the layers of the complex material can also undergo appropriate treatments as required.
On peut notamment par des traitements connus modifier la tension superficielle du tissu non-tissé et rendre les structures fibreuses de ce tissu hydrophile.It is possible in particular by known treatments to modify the surface tension of the nonwoven fabric and to make the fibrous structures of this tissue hydrophilic.
Ceci notamment dans le cas où l'on souhaitera permettre à la nappe du matériau, par sa face correspondante au non-tissé, de présenter les propriétés minimales d'absrptin, tout en évitant le passage des liquides, par exemple des liquides biologiques, sur l'autre face ; en effet dans ce cas la couche de résine qui constitue l'autre face du matériau offre une barrière assurant une imperméabilité aux liquides.This in particular in the case where it is desired to allow the sheet of material, by its face corresponding to the nonwoven, to present the minimal properties of absrptin, while preventing the passage of liquids, for example biological liquids, over the other side; indeed in this case the resin layer which constitutes the other face of the material offers a barrier ensuring impermeability to liquids.
L'invention permet donc la réalisation d'un matériau présentant des propriétés combinées utilisables dans le domaine médical et hospitalier. The invention therefore allows the production of a material having combined properties usable in the medical and hospital field.
Et elle permettra la réalisation d'articles à usage unique, tels que des champs opératoires, mais également des articles vestimentaires tels que blouses de chirurgiens, surbottes, coiffes etc... utilisables en milieu stérile.And it will allow the production of single-use items, such as surgical drapes, but also clothing items such as surgical gowns, overboots, headdresses, etc., which can be used in a sterile environment.
L'invention pourra également trouver des utilisations parallèles dans la réalisation d'articles vestimentaires ou de survêtements, du type à jeter, utilisables dans les salles blanches de préparation, conditionnement ou recondit ionnement de préparations alimentaires. The invention may also find parallel uses in the production of clothing articles or tracksuits, of the disposable type, usable in clean rooms for preparation, packaging or re-packaging of food preparations.
