Description

La présente invention concerne un non-tissé dont la structure frisée ou ondulée lui confère d'excellentes propriétés d'absorption permettant notamment son emploi en tant que compresse médicale ou chirurgicale.The present invention relates to a nonwoven whose curly or wavy structure gives it excellent absorption properties, making it particularly suitable for use as a medical or surgical compress.

Actuellement les compresses médicales sont obtenues à partir d'un tissu léger - appelé gaze à pansements - (grammage compris entre 25 et 28 g/m2) dont la fabrication nécessite l'emploi d'un matériel de tissage coûteux et peu performant. Ce tissu est ensuite plié et découpé en plusieurs dimensions : puis, chaque compresse est, en général, enveloppée individuellement et stérilisée.Currently, medical compresses are obtained from a light fabric - called gauze for dressings - (grammage between 25 and 28 g / m 2 ), the manufacture of which requires the use of expensive and ineffective weaving material. This tissue is then folded and cut into several dimensions: then, each compress is, in general, individually wrapped and sterilized.

Les compresses en gaze traditionnelle sont des produits très plats, adhérant aux plaies et présentant un coefficient d'absorption des fluides assez faible. En outre, leurs caractéristiques d'élasticité et de résilience sont très nettement insuffisantes.Traditional gauze compresses are very flat products, adhering to wounds and having a relatively low coefficient of absorption of fluids. In addition, their elasticity and resilience characteristics are very clearly insufficient.

De nombreuses recherches ont visé à remplacer la gaze par des non-tissés obtenus par voie sèche, par voie humide ou par la technique dite « spun-bonded et composés de mélanges de fibres synthétiques et/ou naturelles.Numerous researches have aimed at replacing the gauze with nonwovens obtained by the dry route, by the wet route or by the technique known as “spun-bonded and composed of mixtures of synthetic and / or natural fibers.

Si les propriétés des compresses en non-tissé sont sensiblement supérieures à celles fabriquées en gaze, pour ce qui est notamment de la non-adhérence aux plaies, elles restent cependant très en deçà de ce qui est désiré quant à la capacité d'absorption.If the properties of non-woven compresses are appreciably superior to those produced in gauze, with regard in particular to non-adhesion to wounds, they nevertheless remain far below what is desired as regards the absorption capacity.

On connaît par le brevet US-A-4 001 472 un non-tissé comprenant au moins un voile de fibres cellulosiques renforcé par une grille non-tissée à laquelle il est fixé au moyen d'un adhésif. Le voile présente un réseau de zones comprimées destinées à former des points de liaison avec les fils de la grille. La surface collée étant réduite à ces points, on évite le blocage de canaux capillaires par lesquels les liquides diffusent dans toute la masse. On améliore ainsi la capacité d'absorption des non-tissés de ce type. Cependant l'emploi d'un adhésif, comme de tout liant chimique, dans un tel produit le rend impropre à un usage médical à cause des risques de dissolution par les désinfectants. Par ailleurs ce produit reste très plat, l'épaisseur apparente coïncidant avec celle du matériau.US Pat. No. 4,001,472 discloses a nonwoven comprising at least one veil of cellulosic fibers reinforced by a nonwoven grid to which it is fixed by means of an adhesive. The veil has a network of compressed zones intended to form connection points with the wires of the grid. The bonded surface being reduced at these points, the blockage of capillary channels through which the liquids diffuse throughout the mass is avoided. This improves the absorption capacity of nonwovens of this type. However, the use of an adhesive, like any chemical binder, in such a product makes it unsuitable for medical use because of the risks of dissolution by disinfectants. Furthermore, this product remains very flat, the apparent thickness coinciding with that of the material.

La présente invention concerne un non-tissé compatible avec un usage médical ou chirurgical palliant les défauts des non-tissés et de la gaze traditionnels. Sa structure particulière permet d'allier des propriétés telles que capacité d'absorption élevée, non-adhérence aux plaies, élasticité et résilience.The present invention relates to a nonwoven compatible with medical or surgical use overcoming the defects of traditional nonwovens and gauze. Its particular structure allows to combine properties such as high absorption capacity, non-adhesion to wounds, elasticity and resilience.

D'une manière générale ce non-tissé pour compresse médicale ou chirurgicale présente une succession d'ondulations uniformément réparties et dont les ventres adjacents sont alternativement disposés au-dessus et au-dessous du plan médian du non-tissé et est constitué d'une grille synthétique sur une des faces de laquelle est fixé par thermoliage un voile de fibres cellulosiques.In general, this nonwoven for medical or surgical compress has a succession of ripples uniformly distributed and whose adjacent bellies are alternately arranged above and below the median plane of the nonwoven and consists of a synthetic grid on one side of which is fixed by thermobonding a web of cellulosic fibers.

En particulier, les ventres contigus de deux ondulations voisines, situés d'un même côté du plan médian du non-tissé sont constitués de petits coussinets adjacents.In particular, the contiguous bellies of two neighboring undulations, situated on the same side of the median plane of the nonwoven, are made up of small adjacent pads.

Le brevet FR-A-2 418 819 montre bien un produit fibreux présentant des ondulations mais d'une part, il comporte une quantité notable de liant le rendant impropre à l'usage médical, d'autre part, les ondulations n'ont qu'une fonction soit décorative soit structurale pour améliorer la rigidité.Patent FR-A-2 418 819 clearly shows a fibrous product having undulations, but on the one hand, it contains a significant amount of binder making it unsuitable for medical use, on the other hand, the undulations have only 'either a decorative or structural function to improve rigidity.

L'invention sera mieux comprise à l'aide des dessins, lesquels représentent des exemples non limitatifs de réalisation du non-tissé :

  • la figure 1 est une vue de dessus du non-tissé,
  • la figure 2 est une vue en coupe de la figure 1 selon un plan parallèle au sens machine du non-tissé,
  • la figure 3 est une vue en coupe de la figure 1 selon un plan perpendiculaire au sens machine du non-tissé,
  • la figure 4 est une vue en perspective d'un non-tissé constitué d'une grille synthétique et d'un voile de fibres cellulosiques.
The invention will be better understood with the aid of the drawings, which represent nonlimiting examples of embodiment of the nonwoven:
  • FIG. 1 is a top view of the nonwoven,
  • FIG. 2 is a sectional view of FIG. 1 along a plane parallel to the machine direction of the nonwoven,
  • FIG. 3 is a sectional view of FIG. 1 along a plane perpendicular to the machine direction of the nonwoven,
  • Figure 4 is a perspective view of a nonwoven consisting of a synthetic grid and a web of cellulosic fibers.

La figure 1 est une vue de dessus d'un non-tissé (1) qui présente un sens machine (2), correspondant au sens longitudinal de production dudit non-tissé, et un sens travers (3) perpendiculaire au sens machine (2).Figure 1 is a top view of a nonwoven (1) which has a machine direction (2), corresponding to the longitudinal direction of production of said nonwoven, and a cross direction (3) perpendicular to the machine direction (2 ).

Ce non-tissé (1) comporte des ondulations ou frisures régulièrement espacées et disposées le long de lignes (5) parallèles au sens machine (2).This nonwoven (1) has corrugations or crimps regularly spaced and arranged along lines (5) parallel to the machine direction (2).

La figure 2 qui est une en coupe de ta figure 1 selon AA, plan parallèle au sens machine (2), montre que le non-tissé présente des ondulations (4) dont les ventres (6, 7) sont alternativement au-dessus et au-dessous de son plan médian (8).Figure 2 which is a section of your Figure 1 along AA, plane parallel to the machine direction (2), shows that the nonwoven has undulations (4) whose bellies (6, 7) are alternately above and below its median plane (8).

La figure 3 qui est une vue en coupe de la figure 1 selon BB, plan perpendiculaire au sens machine (2), montre que les ventres contigus (9, 10) d'ondulations voisines sont constitués de petits coussinets adjacents (11, 12) situés d'un même côté du plan médian (8) du non-tissé. En arrière du plan de coupe on voit le profil des coussinets situés en dessous du plan médian (8). La hauteur et la largeur de ces coussinets sont comprises entre 0,1 et 3 mm.Figure 3 which is a sectional view of Figure 1 along BB, plane perpendicular to the machine direction (2), shows that the contiguous bellies (9, 10) of neighboring corrugations consist of small adjacent pads (11, 12) located on the same side of the median plane (8) of the nonwoven. Behind the cutting plane we see the profile of the pads located below the median plane (8). The height and width of these pads are between 0.1 and 3 mm.

La figure 4 présente une forme préférée de l'invention : le non-tissé est constitué d'une grille synthétique (13) formée de filaments (15) d'un premier polymère enrobés dans une gaine d'un second polymère et reliés par de fines lamelles (16) du second polymère, grille sur une face de laquelle est déposé un voile de fibres cellulosiques (14).FIG. 4 shows a preferred form of the invention: the nonwoven consists of a synthetic grid (13) formed of filaments (15) of a first polymer coated in a sheath of a second polymer and connected by thin strips (16) of the second polymer, grid on one side of which is deposited a web of cellulosic fibers (14).

Le voile (14) est thermolié à la grille (13) : ainsi le non-tissé ne comporte aucun liant chimique et peut donc être utilisé en tant que compresse médicale ou chirurgicale.The veil (14) is thermally bonded to the grid (13): thus the nonwoven does not contain any chemical binder and can therefore be used as a medical or surgical compress.

Selon une forme préférée de l'invention la grille synthétique (13) est une grille bi-étirée comportant dans le sens machine (2) des filaments de polyamide parallèles (15) régulièrement espacés d'une distance comprise entre 0,1 et 3 mm et reliés entre eux par des bandes étroites de polypropylène (16) régulièrement espacées d'une distance comprise entre 0,1 et 3 mm et perpendiculaires aux filaments (15). Le voile (14) de fibres cellulosiques est constitué d'un voile de carde de fibres de coton.According to a preferred form of the invention, the synthetic grid (13) is a bi-stretched grid comprising in the machine direction (2) parallel polyamide filaments (15) regularly spaced by a distance of between 0.1 and 3 mm. and connected together by narrow polypropylene strips (16) regularly spaced by a distance between 0.1 and 3 mm and perpendicular to the filaments (15). The veil (14) of cellulosic fibers consists of a carding veil of cotton fibers.

En outre, ce non-tissé présente l'avantage d'être plus léger que la gaze traditionnelle. La grille (13) a un grammage compris entre 5 et 15 g/m2 de préférence 7 g/m2 et le voile de fibres cellulosiques (14) un grammage compris entre 10 et 20 g/m2, de préférence 16 g/m2.In addition, this nonwoven has the advantage of being lighter than traditional gauze. The grid (13) has a grammage between 5 and 15 g / m 2 preferably 7 g / m 2 and the web of cellulosic fibers (14) a grammage between 10 and 20 g / m 2 , preferably 16 g / m 2 .

Sa densité apparente est inférieure à 0,15 - de préférence 0,1 - et sa capacité d'absorption est supérieure à 13 cm3/g - de préférence 16 cm3/g.Its apparent density is less than 0.15 - preferably 0.1 - and its absorption capacity is greater than 13 cm 3 / g - preferably 16 cm 3 / g.

Le tableau ci-après donne les résultats de mesures effectuées sur le non-tissé selon l'invention, sur de la gaze traditionnelle et sur un non-tissé de commerce dénommé PELY-TEX :
