Description

La présente invention concerne le domaine technique des articles d'entretien pour le nettoyage des surfaces au sol ainsi que les dispositifs de nettoyage pour la mise en oeuvre de tels articles d'entretien et les procédés de fabrication de tels articles d'entretien.The present invention relates to the technical field of maintenance articles for cleaning floor surfaces as well as cleaning devices for the implementation of such maintenance items and methods of manufacturing such maintenance items.

Arrière-plan de l'inventionBackground of the invention

Lorsque l'on souhaite nettoyer une surface au sol, il est connu d'utiliser des articles d'entretien comportant selon leur surface inférieure dite de nettoyage un textile constitué de boucles et/ou poils en microfibres et de boucles et/ou poils de fibres ayant un titrage supérieur à 1 dtex, également désignées sous le terme de fibres de grattage. Les microfibres sont connues pour former un réseau capillaire extrêmement dense qui leur confère une excellente absorption des liquides et une bonne récupération des particules plus petites, telle que la poussière. On comprend par microfibres dans le présent texte toutes fibres dont le titrage est inférieur ou égal à 1 dtex.When it is desired to clean a floor surface, it is known to use cleaning articles comprising, according to their lower cleaning surface, a textile consisting of loops and / or microfibre bristles and loops and / or fiber bristles. having a titration greater than 1 dtex, also referred to as scraping fibers. Microfibers are known to form an extremely dense capillary network that gives them excellent liquid absorption and good recovery of smaller particles, such as dust. Microfibers in the present text include all fibers whose titration is less than or equal to 1 dtex.

Les boucles ou poils formés par des fibres ayant un titre supérieur à 1 dtex confèrent un pouvoir abrasif ou grattant audit article d'entretien afin de détacher les éventuelles salissures disposées sur la surface à nettoyer.The loops or bristles formed by fibers having a titre greater than 1 dtex confer an abrasive or scraping power to said maintenance article in order to detach any dirt disposed on the surface to be cleaned.

Les microfibres ont un pouvoir absorbant tel, que si elles constituent intégralement la surface de nettoyage, l'article d'entretien manipulé à distance à l'aide d'un plateau et d'un balai, adhère tellement fortement sur le sol à nettoyer, en particulier lorsque l'article d'entretien est humide, que l'utilisateur ne parvient plus alors à déplacer ledit article (on parle « d'effet ventouse » généré par le réseau capillaire). Si l'article d'entretien est trop difficile à manipuler, il peut engendrer des troubles musculo-squelettiques (dits TMS) pour son utilisateur, en particulier lorsque ce dernier effectue ces tâches répétitives quotidiennement.Microfibres have such an absorbing power that if they constitute the entire cleaning surface, the maintenance item handled remotely using a tray and a broom, so strongly adheres to the floor to be cleaned, in particular when the maintenance article is wet, the user can no longer move the article (it is called "suction effect" generated by the capillary network). If the article of maintenance is too difficult to handle, it can cause musculoskeletal disorders (so-called TMS) for the user, especially when the user performs these repetitive tasks daily.

Pour pallier cet inconvénient, et améliorer l'ergonomie des articles d'entretien, des fibres de grattage ayant un titre supérieur à 1 dtex sont disposées de façon alternée avec lesdites microfibres. Les fibres de grattage ayant un titre plus élevé que celui des microfibres, sont plus rigides et forment des points d'appui selon la surface dite de nettoyage sur lesquels l'article d'entretien peut glisser sur la surface du sol à nettoyer.To overcome this disadvantage, and improve the ergonomics of maintenance articles, scraping fibers having a title greater than 1 dtex are arranged alternately with said microfibers. Scraping fibers with a higher titer than microfibres are more rigid and form points of support according to the so-called cleaning surface on which the maintenance article can slide on the surface of the soil to be cleaned.

Généralement, de tels articles d'entretien comprennent selon leurs surfaces inférieures -destinées à former la surface dite de nettoyage entrant en contact avec le sol- environ 50% en poids de microfibres par rapport à la proportion en poids de fibres sur lesdites faces inférieures, le restant étant formé de fibres ayant un titre supérieur à 1 dtex.Generally, such maintenance articles comprise, according to their lower surfaces - intended to form the so-called cleaning surface coming into contact with the floor - about 50% by weight of microfibers with respect to the proportion by weight of fibers on said lower faces, the remainder being fibers having a titre greater than 1 dtex.

Ces articles d'entretien peuvent être laminés avec une mousse ou comporter d'autres panneaux textiles absorbants disposés sur leurs faces supérieures.These maintenance articles may be laminated with a foam or comprise other absorbent textile panels disposed on their upper faces.

De tels articles d'entretien sont ainsi limités dans la quantité de microfibres que leurs surfaces de nettoyage peuvent présenter ainsi que par leur finesse (ou titre en dtex). En effet, plus les microfibres sont fines (i.e plus leur titre (dtex) est faible), mieux elles absorbent les liquides et récupèrent les poussières présentes sur le sol, mais plus elles ont tendance à adhérer à la surface de nettoyage au sol, rendant leur utilisation difficile.Such maintenance articles are thus limited in the amount of microfiber that their cleaning surfaces can present as well as in their fineness (or dtex title). In fact, the finer the microfibers (ie, the lower their titre (dtex)), the better they absorb the liquids and recover the dust present on the ground, but the more they tend to adhere to the floor cleaning surface, making their difficult use.

Par ailleurs, les microfibres ayant une capacité d'absorption et de récupération plus importantes que les fibres grattantes, il y a donc un intérêt à rechercher l'optimisation de leur quantité et/ou de leur finesse selon la surface de nettoyage des articles d'entretien.Moreover, since microfibers have a higher absorption and recovery capacity than scratching fibers, there is therefore an interest in seeking the optimization of their quantity and / or fineness according to the cleaning surface of the articles. interview.

A chaque surface et zone de nettoyage déterminées correspond un article d'entretien, en particulier lorsque le nettoyage est effectué par des professionnels dans des locaux à usage professionnel. Pour le nettoyage des surfaces au sol de pièces dans lesquelles on cherche à maitriser et éviter la production de particules (poussières, cheveux, peaux,....), il est important de ne pas introduire dans ces pièces d'articles d'entretien susceptibles de libérer ces particules. De telles pièces peuvent être, par exemple, des salles blanches, des salles de chirurgie, des salles de fabrication de produits électroniques ou pharmaceutiques. Les articles d'entretien utilisés pour le nettoyage de ces pièces peuvent même être lavés puis stérilisés avant leur utilisation. Les articles d'entretien utilisés à ce jour pour nettoyer ces pièces se présentent sous la forme d'un complexe multicouche. Ce complexe comprend deux couches externes entre lesquelles sont disposées une pluralité de feutre ou autres couches absorbantes, tels que des nontissés. La couche externe peut comprendre des microfibres. Le complexe comprend en outre une couture, par exemple un surjet, effectué sur tout son pourtour afin de maintenir les couches ensembles et limiter la perte de particules. Une couture transversale sur toute l'épaisseur du complexe est également requise afin d'empêcher les multiples couches intermédiaires de vriller dans la poche délimitée entre les couches externes solidarisées selon leurs bordures et faciliter la manipulation du complexe. Ce type de complexe présente un taux d'absorption compris entre 200% et 400% en eau par rapport à sa masse sèche.At each surface and cleaning area determined is a maintenance item, especially when the cleaning is done by professionals in professional premises. For the cleaning of the floor surfaces of rooms in which we try to control and avoid the production of particles (dust, hair, skin, ....), it is important not to introduce into these rooms maintenance articles likely to release these particles. Such parts may be, for example, clean rooms, surgical rooms, manufacturing rooms for electronic or pharmaceutical products. Maintenance items used for cleaning these parts can even be washed and sterilized before use. The maintenance items used to date to clean these parts are present in the form of a multilayer complex. This complex comprises two outer layers between which are disposed a plurality of felt or other absorbent layers, such as nonwovens. The outer layer may comprise microfibers. The complex further comprises a seam, for example an overlock, performed all around its periphery to maintain the layers together and limit the loss of particles. A transverse seam over the entire thickness of the complex is also required to prevent the multiple intermediate layers from twisting in the pocket delimited between the outer layers secured along their edges and facilitate handling of the complex. This type of complex has an absorption rate of between 200% and 400% water relative to its dry mass.

La présence de multiples coutures et de nombreuses couches rend fastidieuse et couteuse la confection d'un tel complexe multicouche. De plus, la présence des coutures et des nombreuses couches favorise le relargage de particules. Enfin la structure en multicouches superposées rend difficile la restitution en eau absorbée et limite la superficie de la surface à nettoyer à 15m2 environ.The presence of multiple seams and many layers makes tedious and expensive the making of such a multilayer complex. In addition, the presence of seams and many layers promotes the release of particles. Finally, the multilayer structure superimposed makes it difficult to return water absorbed and limits the area of the surface to be cleaned to 15m 2 approximately.

Il existe donc un besoin pour un article d'entretien ayant une capacité d'absorption en eau importante, limitant le relargage de particules et la prolifération des bactéries.There is therefore a need for a maintenance article having a high water absorption capacity, limiting the release of particles and the proliferation of bacteria.

Il existe également un besoin pour un article d'entretien simplifié, qui puisse être réutilisable et donc lavable, ayant une bonne tenue au lavage, et ergonomique.There is also a need for a simplified maintenance article, which can be reusable and therefore washable, with good washing behavior, and ergonomic.

Enfin, il existe un besoin pour un article d'entretien qui soit facilement recyclable, et d'un coût de fabrication maîtrisé afin de pouvoir être jetable (usage unique).Finally, there is a need for a maintenance item that is easily recyclable, and a controlled manufacturing cost to be disposable (single use).

Objet et résumé de l'inventionObject and summary of the invention

La présente invention a pour objet, selon un premier aspect, un article d'entretien pour le nettoyage d'une surface déterminée, palliant tout ou partie des problèmes ci-dessus mentionnés, comprenant avantageusement une pièce textile en trois dimensions, de construction tricotée unitaire, comprenant une première couche textile tricotée et une seconde couche textile tricotée, reliées par des fils de liaison s'étendant entre la première couche textile et la seconde couche textile. La première couche textile comprend, sur sa face externe dite de nettoyage, des microfibres, et éventuellement des fibres de grattage ayant un titrage supérieur à 1 dtex. De plus, les fils de liaison forment une couche intermédiaire absorbant l'eau.The subject of the present invention is, according to a first aspect, a maintenance article for cleaning a given surface, overcoming all or part of above-mentioned problems, advantageously comprising a three-dimensional textile piece, of unitary knit construction, comprising a first knitted textile layer and a second knitted textile layer, connected by connecting threads extending between the first textile layer and the second textile layer. The first textile layer comprises, on its outer face called cleaning, microfibers, and possibly scraping fibers having a titration greater than 1 dtex. In addition, the bonding wires form a water-absorbing intermediate layer.

Avantageusement, la couche intermédiaire comprenant les fils de liaison est capable de restituer l'eau absorbée progressivement pour le nettoyage de la surface déterminée sous l'effet de la pression exercée sur cette dernière lorsque l'article d'entretien est appliqué avec une certaine pression (pression manuelle de l'utilisateur par exemple) sur la surface à nettoyer.Advantageously, the intermediate layer comprising the binding son is capable of returning the absorbed water gradually for cleaning the determined surface under the effect of the pressure exerted on the latter when the maintenance article is applied with a certain pressure (manual pressure of the user for example) on the surface to be cleaned.

Avantageusement, la pièce textile étant de construction tricotée unitaire, sa construction est simplifiée. L'ergonomie de l'article d'entretien est également améliorée comparativement aux complexes multicouches de l'état de la technique.Advantageously, the textile piece being of unitary knit construction, its construction is simplified. The ergonomics of the article of maintenance is also improved compared to multi-layer complexes of the state of the art.

Le fait que l'article d'entretien soit en une seule pièce facilite sa découpe, évitant ainsi de multiples découpes de plusieurs couches en vue de leur assemblage.The fact that the maintenance article is in one piece facilitates its cutting, thus avoiding multiple cuts of several layers for assembly.

On comprend par l'expression « une pièce textile de construction tricotée unitaire » que la pièce textile comprenant les première et seconde couches textiles tricotées et la couche intermédiaire comprenant les fils de liaison, est formée intégralement par tricotage sur un métier à tricoter.It is understood by the expression "a textile piece of unitary knitted construction" that the textile piece comprising the first and second knitted textile layers and the intermediate layer comprising the binding threads, is integrally formed by knitting on a knitting machine.

On comprend par titre (ou titrage) moyen (dtex) des fibres présentes sur la surface dite de nettoyage, et de manière générale des fibres dans la pièce textile selon l'invention, la moyenne pondérale des titres (dtex) des différentes fibres.The term "titration" (or titration) means (dtex) fibers present on the so-called cleaning surface, and generally fibers in the textile part according to the invention, the weight average of the titers (dtex) of the different fibers.

On désigne dans le présent texte sous le terme de fibre (que ce soit une fibre de grattage ou une microfibre), une fibre ou un filament.Fiber (either a scraping fiber or a microfiber), a fiber or a filament is referred to herein as the fiber.

De préférence, la première couche est différente de la seconde couche, en particulier de par leur composition en fibres et/ou leur schéma de mailles. Encore de préférence, la seconde couche textile (considérée sans les fils de liaison) ne comprend pas de microfibres.Preferably, the first layer is different from the second layer, in particular because of their fiber composition and / or their mesh pattern. Even more preferably, the second textile layer (considered without the connecting threads) does not include microfibers.

De préférence, la première couche est la couche fonctionnelle de la pièce textile tricotée supportant les fibres de grattage et/ou les microfibres tandis que la seconde couche assure la configuration en trois dimensions de la pièce textile par sa liaison avec la première couche par l'intermédiaire des fils de liaison.Preferably, the first layer is the functional layer of the knitted fabric piece supporting the scraping fibers and / or the microfibers while the second layer provides the three-dimensional configuration of the textile piece by its connection with the first layer by the intermediate connecting wires.

Les fibres de grattage selon l'invention sont de préférence des fils multi-filamentaires et/ou des fils mono-filamentaires, ayant un titre supérieur à 1 dtex, en particulier chaque filament d'un fil multifilamentaire et/ou un fil mono-filamentaire a un titre supérieur à 1 dtex.The scraping fibers according to the invention are preferably multi-filament yarns and / or monofilament yarns, having a titre greater than 1 dtex, in particular each filament of a multifilament yarn and / or a monofilament yarn has a title greater than 1 dtex.

On désigne par le terme de microfibre, une fibre ou un filament. Une microfibre se présente ainsi de préférence sous la forme d'un (micro)filament d'un fil multi-filamentaire (les dits filaments pouvant être irréguliers du fait de leur procédé d'obtention, bien connu de l'homme du métier).The term microfiber refers to a fiber or filament. A microfiber is thus preferably in the form of a (micro) filament of a multi-filament yarn (the said filaments being able to be irregular because of their method of production, well known to those skilled in the art).

Les microfibres et les fibres de grattage, et éventuellement les fils de liaison, sont de préférence choisi(e)s parmi les polymères suivants : polyamide 6, polyamide 6-6, polyamide 4-6, polyamide 12, polyéthylène téréphtalate, polypropylène et polyéthylène, ou leurs mélanges, de préférence en polyéthylène téréphtalate.The microfibers and the scraping fibers, and optionally the binding threads, are preferably chosen from the following polymers: polyamide 6, polyamide 6-6, polyamide 4-6, polyamide 12, polyethylene terephthalate, polypropylene and polyethylene or mixtures thereof, preferably polyethylene terephthalate.

Les fibres de grattage, et éventuellement les fils de liaison (à l'exception des microfibres), peuvent comprendre des fibres et/ou fils absorbant les mauvaises odeurs, notamment à base de café, telles que les fibres commercialisées sous la marque s.café®.The scraping fibers, and possibly the binding yarns (with the exception of microfibers), may comprise fibers and / or yarns that absorb bad odors, especially those based on coffee, such as the fibers marketed under the brand name s.café. ®.

Avantageusement, la pièce textile tricotée est dans un seul polymère, en particulier en polyéthylène téréphtalate (PET), ce qui facilite son recyclage.Advantageously, the knitted textile piece is in a single polymer, in particular polyethylene terephthalate (PET), which facilitates its recycling.

Dans un mode de réalisation, la pièce textile tricotée est dans un ou plusieurs matériau(x) polymère(s) thermoplastique(s).In one embodiment, the knitted textile piece is in one or more thermoplastic polymer (s) material (s).

Les microfibres, en particulier chaque microfilament d'un fil multi-filamentaire, ont/a de préférence un titre inférieur ou égal à 1 dtex, de préférence inférieur ou égal à 0,87 dtex.Microfibers, in particular each microfilament of a multi-filament yarn, preferably have a titer of less than or equal to 1 dtex, preferably less than or equal to 0.87 dtex.

De préférence, les microfibres, en particulier chaque microfilament d'un fil multi-filamentaire, ont/a un titre de l'ordre de 0,58 dtex ou de 0,26 dtex, à +/-0,15 dtex près.Preferably, the microfibers, in particular each microfilament of a multi-filament yarn, have a title of the order of 0.58 dtex or 0.26 dtex, within +/- 0.15 dtex.

Un tel fil multi-filamentaire peut être, par exemple, un fil multi-filamentaires de 167 dtex pour 192 filaments ou 288 filaments, ou encore de 78 dtex pour 300 filaments.Preferably, the microfibers are in the form of multifilament yarns. Such a multi-filament yarn may be, for example, a multi-filament yarn of 167 dtex for 192 filaments or 288 filaments, or 78 dtex for 300 filaments.

De préférence, les fibres de grattage, en particulier chaque filament d'un fil multifilamentaire de grattage et/ou un fil mono-filamentaire de grattage, ont/a un titre supérieur à 1 dtex, encore de préférence supérieur ou égal à 3 dtex, en particulier inférieur ou égal à 65 dtex, plus particulièrement inférieur ou égal à 46 dtex.Preferably, the scraping fibers, in particular each filament of a multifilament scraping yarn and / or a monofilament scraping yarn, have a titre greater than 1 dtex, more preferably greater than or equal to 3 dtex, in particular less than or equal to 65 dtex, more particularly less than or equal to 46 dtex.

Le calcul du titre (dtex) d'une fibre (et donc d'un fil) est bien connu de l'homme du métier, il existe de nombreuses normes qui permettent de le calculer, dont notamment les normes suivantes citées de façon non exhaustive :

  • NF G01-001 : Expression de la masse linéique - Système TEX ;
  • NF EN ISO 1973 : Détermination de la masse linéique : méthode gravimétrique et méthode au vibroscope ;
  • ISO 7211-5 : 1984 : Tissus. Construction. Méthode d'analyse. Partie 5 : détermination de la masse linéique d'un fil prélevé dans un tissu.
The calculation of the title (dtex) of a fiber (and therefore of a thread) is well known to those skilled in the art, there are many standards that allow to calculate it, including in particular the following standards cited in a non-exhaustive way :
  • NF G01-001: Linear mass expression - TEX system;
  • NF EN ISO 1973: Determination of linear density: gravimetric method and vibroscope method;
  • ISO 7211-5: 1984: Fabrics. Construction. Method of analysis. Part 5: Determination of the linear density of a yarn taken from a fabric.

Les valeurs données dans le présent texte sont indiquées à plus ou moins 10%.The values given in this text are indicated at plus or minus 10%.

Dans une variante, la première couche textile et la seconde couche textile sont chacune un tricot à mailles jetées.In a variant, the first textile layer and the second textile layer are each a knitted mesh knit.

Cette disposition permet d'agencer les fibres de grattage et les microfibres selon de nombreux motifs et/ou d'agencer des jours dans la première couche de taille et forme variées.This arrangement makes it possible to arrange the scraping fibers and the microfibers according to numerous patterns and / or to arrange days in the first layer of varied size and shape.

La pièce textile en trois dimensions selon l'invention est de préférence tricotée sur un métier à tricoter comprenant deux fontures (ou lits) d'aiguilles, par exemple un métier à tricoter Rachel, tels que ceux commercialisés par la société Karl Mayer.The three-dimensional textile piece according to the invention is preferably knitted on a knitting machine comprising two needle beds (or beds), for example a Rachel knitting machine, such as those marketed by the company Karl Mayer.

De préférence, la masse surfacique (g/m2) de la pièce textile en trois dimensions est supérieure ou égale à 100 g/m2, encore de préférence supérieure ou égale à 150 g/m2, encore plus préférentiellement supérieure ou égale à 200 g/m2, en particulier supérieure ou égale à 250 g/m2.Preferably, the density (g / m 2 ) of the textile piece in three dimensions is greater than or equal to 100 g / m 2 , more preferably greater than or equal to 150 g / m 2 , even more preferably greater than or equal to 200 g / m 2 , in particular greater than or equal to 250 g / m 2 .

De préférence, la masse surfacique (g/m2) de la pièce textile en trois dimensions est inférieure ou égale à 850 g/m2, encore de préférence inférieure ou égale à 750 g/m2, encore plus préférentiellement inférieure ou égale à 650 g/m2, en particulier inférieure ou égale à 550 g/m2, plus particulièrement inférieure ou égale à 500 g/m2.Preferably, the density (g / m 2 ) of the textile part in three dimensions is less than or equal to 850 g / m 2 , more preferably less than or equal to 750 g / m 2 , even more preferably less than or equal to 650 g / m 2 , in particular less than or equal to 550 g / m 2 , more particularly less than or equal to 500 g / m 2 .

Dans une variante, les fils de liaison comprennent des microfibres.In one variant, the connecting threads comprise microfibers.

Avantageusement, la pièce textile selon l'invention permet d'atteindre des seuils d'absorption en eau de l'ordre de 600%, ce qui est très nettement supérieur à la capacité d'absorption des complexes multicouches de l'état de la technique entre 200% et 400%.Advantageously, the textile piece according to the invention makes it possible to reach water absorption thresholds of the order of 600%, which is very clearly greater than the absorption capacity of the multilayer complexes of the state of the art. between 200% and 400%.

Dans une variante, les fils de liaison comprennent des fils mono-filamentaires.In a variant, the connection son comprise monofilament son.

Cette disposition améliore la résistance à la compression entre les première et seconde couches de la pièce textile lorsque l'article d'entretien est appliqué sur la surface à nettoyer, ainsi que l'ergonomie de l'article d'entretien puisque sa tenue est améliorée.This arrangement improves the compressive strength between the first and second layers of the textile part when the maintenance article is applied to the surface to be cleaned, as well as the ergonomics of the article of maintenance since its behavior is improved. .

De préférence, un fil mono-filamentaire a un titre supérieur ou égal à 20 dtex et inférieur ou égal à 60 dtex, en particulier inférieur ou égal à 50 dtex.Preferably, a monofilament yarn has a titre greater than or equal to 20 dtex and less than or equal to 60 dtex, in particular less than or equal to 50 dtex.

Dans une variante, un fil mono-filamentaire a un diamètre supérieur ou égal à 10 µm (microns), de préférence supérieur ou égal à 15 µm (microns), en particulier inférieur ou égal à 90 µm (microns), plus particulièrement inférieur ou égal à 70 µm (microns).In one variant, a monofilament yarn has a diameter greater than or equal to 10 μm (microns), preferably greater than or equal to 15 μm (microns), in particular less than or equal to 90 μm (microns), more particularly less than or equal to equal to 70 μm (microns).

Dans une variante, les fils de liaison comprennent des microfibres et des fils mono-filamentaires.In one variant, the connecting threads comprise microfibers and monofilament yarns.

Cette combinaison des microfibres et des fils monofilamentaires pour la couche intermédiaire permet d'améliorer l'ergonomie de l'article d'entretien, sa résistance à la compression mais également de favoriser les propriétés de la couche intermédiaire : à savoir l'absorption d'eau et sa restitution lorsqu'elle est comprimée.This combination of microfibres and monofilament yarns for the intermediate layer makes it possible to improve the ergonomics of the article of maintenance, its compressive strength, but also to favor the properties of the intermediate layer: namely the absorption of water and its restitution when it is compressed.

Dans une variante, la pièce textile en trois dimensions comprend selon tout ou partie de son pourtour (c'est-à-dire de sa bordure externe) une zone de solidarisation dans laquelle les première et seconde couches textiles, et les fils de liaison, sont thermosoudés.In one variant, the three-dimensional textile piece comprises, according to all or part of its periphery (that is to say of its external border), a zone of attachment in which the first and second textile layers, and the connecting threads, are heat sealed.

De préférence, la zone de soudure est obtenue par soudure ultrasons.Preferably, the welding zone is obtained by ultrasonic welding.

Dans la zone de soudure, les première et seconde couches ainsi que les fils de liaison sont fondus, au moins partiellement, il n'y a pas d'espace généré entre des trous et des fils de couture comme cela est le cas dans l'état de la technique, ce qui évite, ou à tout le moins limite, l'émission de particules par la couche intermédiaire à l'extérieur de l'article d'entretien.In the weld zone, the first and second layers as well as the bonding wires are melted, at least partially, there is no space generated between holes and sewing threads as is the case in the state of the art, which avoids, or at least limit, the emission of particles by the intermediate layer outside the maintenance article.

La zone de solidarisation pourrait également être effectuée, de manière alternative, par couture, mais cette technique représente moins d'avantages dans le cadre de la présente invention.The securing zone could also be performed, alternatively, by sewing, but this technique represents less advantages in the context of the present invention.

De plus, l'article d'entretien avec une zone de solidarisation thermosoudée présente un aspect radicalement différent des articles de l'état de la technique, et une esthétique améliorée.In addition, the maintenance article with a heat-sealed fastening zone has a radically different aspect of articles of the state of the art, and improved aesthetics.

Dans un mode de réalisation, la zone de soudure est de préférence obtenue lors de la découpe de la pièce textile dans le panneau textile tricoté.In one embodiment, the weld zone is preferably obtained during the cutting of the textile piece in the knitted textile panel.

Avantageusement, la découpe de la pièce textile et la finition de sa bordure sont réalisées en une seule et même opération.Advantageously, the cutting of the textile piece and the finishing of its border are performed in one and the same operation.

Dans une variante, la couche intermédiaire a une épaisseur supérieure ou égale à 1 mm, de préférence inférieure ou égale à 20 mm, encore de préférence inférieure ou égale à 10 mm, en particulier inférieure ou égale à 6 mm.In a variant, the intermediate layer has a thickness greater than or equal to 1 mm, preferably less than or equal to 20 mm, more preferably less than or equal to 10 mm, in particular less than or equal to 6 mm.

Dans une variante, la première couche textile comprend des jours, ayant notamment au moins une dimension supérieure ou égale à 1 mm. Par définition, un jour est une zone sans fibres.In a variant, the first textile layer comprises days, in particular having at least one dimension greater than or equal to 1 mm. By definition, a day is a zone without fibers.

Ces jours débouchent sur la couche intermédiaire ce qui facilite l'absorption de fluide, en particulier de l'eau, par la couche intermédiaire, en particulier par les fils de liaison.These days lead to the intermediate layer which facilitates the absorption of fluid, in particular water, by the intermediate layer, in particular by the connecting son.

Ces jours dans la première couche peuvent avoir n'importe quelle forme à partir du moment qu'ils débouchent sur la couche intermédiaire.These days in the first layer can have any shape from the moment that they come to the intermediate layer.

Dans une variante, la première couche textile comprend, sur sa face externe dite de nettoyage, des microfibres alternées avec des fibres de grattage selon un premier motif.In a variant, the first textile layer comprises, on its outer face, said cleaning surface, alternating microfibers with scraping fibers in a first pattern.

Dans une variante, la face externe de la première couche comprend une partie avant et une partie arrière dans le prolongement l'une de l'autre ayant des faces externes respectives, la partie avant comprend, selon sa face externe, des microfibres et des fibres de grattage, la partie arrière comprend, selon sa face externe, des microfibres, et éventuellement des fibres de grattage ayant un titre supérieur à 1 dtex. Le titre moyen T1 (dtex) des microfibres et des fibres de grattage sur ladite face externe de la partie avant est supérieur ou égal à 0,5 dtex, le titre moyen T2 (dtex) des microfibres, et éventuellement des fibres de grattage, sur la face externe de la partie arrière est inférieur ou égal à 2 dtex, et le titre moyen T1 (dtex) est différent du titre moyen T2 (dtex).In a variant, the outer face of the first layer comprises a front portion and a rear portion in the extension of one another having respective outer faces, the front portion comprises, according to its outer face, microfibers and fibers. scraping, the rear portion comprises, according to its outer face, microfibres, and possibly scraping fibers having a title greater than 1 dtex. The average titer T1 (dtex) of the microfibers and scraping fibers on said outer face of the front part is greater than or equal to 0.5 dtex, the average titer T2 (dtex) of the microfibres, and possibly scraping fibers, on the outer face of the rear part is less than or equal to 2 dtex, and the average title T1 (dtex) is different from the average title T2 (dtex).

Avantageusement, le réseau capillaire entre les parties avant et arrière est différencié, l'article d'entretien présente un pouvoir d'adhérence sur la surface de nettoyage au sol différent entre la face externe de la partie avant et la face externe de la partie arrière et donc une capacité de récupération et d'absorption des salissures différentes entre ces parties.Advantageously, the capillary network between the front and rear parts is differentiated, the maintenance article has a power of adhesion on the different floor cleaning surface between the outer face of the front part and the outer face of the rear part. and therefore a capacity for recovery and absorption of different soils between these parts.

Les intervalles de titres spécifiés pour chacune des parties confèrent à la face externe de la partie avant la fonction de glissance sur la surface au sol à nettoyer. La face externe de la partie avant forme ainsi la face « d'attaque », c'est-à-dire la face à partir de laquelle l'utilisateur fait glisser l'article d'entretien sur la surface au sol.The titration intervals specified for each of the parts give the outer face of the front part the sliding function on the floor surface to be cleaned. The outer face of the front part thus forms the face "attack", that is to say the face from which the user slides the maintenance item on the floor surface.

Les masses surfaciques (g/m2) et titre (dtex) indiqués par rapport à la première (ou seconde) couche sont calculés sur la première (ou seconde) couche exempte des fils de liaison. En effet, les fils de liaison s'étendant entre les première et seconde couches, sont liés à la structure de la première (et de la seconde) couche mais ne sont pas comptés comme faisant partie de la première (ou de la seconde) couche lorsque des calculs sont effectués concernant le titre moyen de la première couche (par rapport aux microfibres et/ou aux fibres de grattage) et le poids (g) ou masse surfacique (g/m2) de la première couche.The surface weights (g / m 2 ) and the density (dtex) indicated relative to the first (or second) layer are calculated on the first (or second) layer free of the connecting wires. Indeed, the bonding wires extending between the first and second layers are bonded to the structure of the first (and second) layer but are not counted as part of the first (or second) layer. when calculations are made concerning the average titre of the first layer (with respect to microfibers and / or scraping fibers) and the weight (g) or basis weight (g / m 2 ) of the first layer.

Les inventeurs ont ainsi observé de façon surprenante que la face externe de la partie avant décolle les salissures et les récupère grâce aux microfibres qu'elle comporte et que la face externe de la partie arrière récupère encore davantage de poussières et autres salissures que celle de la partie avant. Cette constatation est faite visuellement.The inventors have thus surprisingly observed that the outer face of the front part takes off the stains and recovers them thanks to the microfibers which it comprises and that the external face of the rear part recovers even more dust and other soiling than that of the front part. This finding is made visually.

De plus, l'utilisateur n'a aucune difficulté à faire glisser l'article d'entretien sur la surface au sol du moment qu'il débute le déplacement dudit article selon sa surface dite de nettoyage par la face externe de la partie avant.In addition, the user has no difficulty in sliding the maintenance item on the ground surface as it begins the movement of said article according to its so-called cleaning surface by the outer face of the front portion.

Les parties avant et arrière sont dans le prolongement l'une de l'autre et sont constituées de la première couche textile.The front and rear parts are in the extension of one another and consist of the first textile layer.

Les valeurs spécifiées concernant les titres moyens ou encore les proportions en poids de fibres sont calculées par rapport aux fibres présentes sur les surfaces externes des parties avant et arrière de la première couche, exempte des fils de liaison.The specified values for the average strengths or the proportions by weight of fibers are calculated with respect to the fibers present on the outer surfaces of the front and back portions of the first layer, which are free of the connecting threads.

Dans une variante, le titre moyen T1 (dtex) est supérieur au titre moyen T2 (dtex).In a variant, the average titer T1 (dtex) is greater than the average titer T2 (dtex).

Dans une variante, la partie arrière de la première couche comprend, selon sa face externe, une proportion en poids de microfibres supérieure à la proportion en poids de microfibres de la partie avant, par rapport au poids total de la première couche.In a variant, the rear portion of the first layer comprises, according to its external face, a proportion by weight of microfibers greater than the proportion by weight of microfibres of the front part, relative to the total weight of the first layer.

Dans une variante, les microfibres et les fibres de grattage sur la face externe de la partie avant de la première couche sont alternées de façon répétée selon un premier motif donné, et les microfibres et les fibres de grattage sur la face externe de la partie arrière de la première couche sont alternées de façon répétée selon un second motif donné, éventuellement le premier motif est différent du second motif.In a variant, the microfibres and the scraping fibers on the outer face of the front part of the first layer are alternately alternated according to a given first pattern, and the microfibers and the scratching fibers on the outer face of the rear part. of the first layer are alternately repeated in a second given pattern, possibly the first pattern is different from the second pattern.

Dans une variante, le premier motif et/ou le second motif est/sont choisi(s) parmi : des lignes alternées continues ou discontinues de microfibres et/ou de fibres de grattage, des zig-zags de microfibres et/ou de fibres de grattage, des ilots ou zones localisées de fibres de grattage ou de microfibres.In a variant, the first pattern and / or the second pattern is / are chosen from: alternating continuous or discontinuous lines of microfibers and / or scraping fibers, zigzags of microfibres and / or fibers of scraping, islands or localized areas of scratch or microfiber fibers.

Dans une variante, la seconde couche comprend selon sa face externe des moyens d'attache aptes à coopérer avec des moyens d'attache complémentaires disposés sur le plateau d'un balai.In a variant, the second layer comprises, according to its external face, fastening means capable of cooperating with complementary fastening means arranged on the plate of a broom.

Lesdits moyens d'attache peuvent être formés par la structure de la seconde couche textile, en particulier tricotée, en sorte de coopérer avec les moyens d'attache complémentaires, tels que des crochets.Said fastening means may be formed by the structure of the second textile layer, in particular knitted, so as to cooperate with the complementary fastening means, such as hooks.

Dans une variante, la pièce textile comprend deux poches latérales formées par repliement et solidarisation partielle des deux extrémités latérales de ladite pièce, en particulier selon au moins ladite zone de solidarisation, chaque poche étant agencée en sorte d'être apte à recevoir une extrémité latérale d'un plateau d'un dispositif de nettoyage.In one variant, the textile part comprises two lateral pockets formed by folding and partially joining the two lateral ends of said part, in particular according to at least said joining zone, each pocket being arranged so as to be able to receive a lateral end. a tray of a cleaning device.
