Abstract
Description
L'invention concerne l'utilisation d'une étoffe non tissée comme sous-couche d'un tissu de recouvrement de sièges destinés au transport de personnes par route, rail ou air. L'invention concerne également le revêtement de siège composé d'un tissu contrecollé ou non avec ladite étoffe, ainsi que le siège destiné au transport de personnes, comportant ce revêtement.The invention relates to the use of a nonwoven fabric as an underlay for a fabric for covering seats intended for the transport of persons by road, rail or air. The invention also relates to the seat covering composed of a fabric laminated or not with said fabric, as well as the seat intended for the transport of persons, comprising this covering.
Par étoffe non tissée, on entend comprendre ce que l'on appelle habituellement un tissu non tissé, une nappe non tissée ou un feutre.By nonwoven fabric is meant to understand what is usually called a nonwoven fabric, a nonwoven web or a felt.
Pour assurer le confort de l'utilisateur, un siège comprend généralement 1 °) un support assurant le confort ergonomique de l'utilisateur du siège; ce support est généralement constitué de mousse dense, de ressorts ou de bandes, 2°) une couche de rembourrage constituée d'une mousse moins dense que celle constituant le support (et éventuellement séparée du support par un film de séparation) et 3°) un tissu de recouvrement. La couche de rembourrage et le tissu de recouvrement sont responsables de l'aspect thermophysiologique du confort.To ensure the comfort of the user, a seat generally comprises 1) a support ensuring the ergonomic comfort of the user of the seat; this support is generally made of dense foam, springs or bands, 2 °) a padding layer made of a less dense foam than that constituting the support (and possibly separated from the support by a separating film) and 3 °) a covering fabric. The padding layer and the covering fabric are responsible for the thermophysiological aspect of comfort.
Un siège ainsi constitué est particulièrement isolant, ce qui entraîne un dégagement de sueur par l'utilisateur. Si cette transpiration n'est pas rapidement évacuée, il s'ensuit une sensation désagréable d'humidité.A seat thus formed is particularly insulating, which results in the release of sweat by the user. If this perspiration is not quickly removed, an unpleasant feeling of humidity follows.
L'effet isolant du siège est principalement dû à l'importante épaisseur de mousse dense constituant le support, au film séparant la mousse dense de la mousse de rembourrage et au caractère fermé de la mousse de rembourrage qui renferme une multitude de bulles d'air.The insulating effect of the seat is mainly due to the large thickness of dense foam constituting the support, to the film separating the dense foam from the padding foam and to the closed character of the padding foam which contains a multitude of air bubbles. .
L'évacuation de l'humidité due à la transpiration de l'utilisateur ne peut se faire à travers l'épaisseur du siège, car le bloc de mousse constituant le support bloque le transport d'humidité.The evacuation of the humidity due to the perspiration of the user cannot be done through the thickness of the seat, because the block of foam constituting the support blocks the transport of humidity.
L'humidité doit donc s'éliminer soit par les côtés, soit par ventilation, c'est-à-dire par effet de pompage dû aux mouvements et aux vibrations.Moisture must therefore be eliminated either by the sides or by ventilation, that is to say by pumping effect due to movements and vibrations.
La présente invention a pour but d'utiliser une étoffe non tissée comme sous-couche du tissu de recouvrement d'un siège, en remplacement de la couche de rembourrage en mousse. Il est notamment visé que l'étoffe non tissée utilisée suivant l'invention remplisse, à la fois les fonctions de couche de rembourrage et de couche de confort thermophysiologique.The object of the present invention is to use a non-woven fabric as an underlayer of the fabric for covering a seat, replacing the layer of foam padding. It is particularly intended that the nonwoven fabric used according to the invention fulfills both the functions of padding layer and thermophysiological comfort layer.
Plus particulièrement, la présente invention a pour but d'utiliser une étoffe non tissée qui soit capable d'absorber rapidement la transpiration émise par l'utilisateur du siège, au niveau de la zone de contact entre l'utilisateur et le siège.More particularly, the present invention aims to use a non-woven fabric which is capable of rapidly absorbing the perspiration emitted by the user of the seat, at the level of the contact zone between the user and the seat.
Il est donc visé que l'étoffe mise en oeuvre suivant l'invention ait, de par son caractère hydrophile, la capacité d'absorber rapidement l'humidité avant de la transporter vers l'extérieur.It is therefore intended that the fabric used according to the invention has, by its hydrophilic nature, the capacity to rapidly absorb moisture before transporting it to the outside.
Un autre but de la présente invention est d'utiliser une étoffe non tissée capable de transporter l'humidité dans une direction parallèle à la surface de l'étoffe.Another object of the present invention is to use a nonwoven fabric capable of transporting moisture in a direction parallel to the surface of the fabric.
La présente invention a également pour but d'utiliser une étoffe non tissée permettant l'évacuation de l'humidité par ventilation.The present invention also aims to use a non-woven fabric allowing the evacuation of moisture by ventilation.
Il est notamment visé que l'étoffe utilisée suivant l'invention ait des caractéristiques de résistance à la compression et d'élasticité suffisantes pour permettre l'absorption, le transport et l'évacuation de l'humidité.It is particularly intended that the fabric used according to the invention has sufficient compressive strength and elasticity characteristics to allow absorption, transport and evacuation of moisture.
La présente invention a pour objet l'utilisation d'une étoffe non tissée comme sous-couche d'un tissu de recouvrement de sièges destinés au transport de personnes (par route, rail ou air), en remplacement de la traditionnelle couche de rembourrage en mousse.The present invention relates to the use of a non-woven fabric as an underlayer of a fabric for covering seats intended for the transport of persons (by road, rail or air), replacing the traditional layer of padding in foam.
L'étoffe non tissée utilisée suivant l'invention est produite par voie sèche. Elle possède une densité comprise entre 20 et 100 kg/m3 et, de préférence, comprise entre 30 et 60 kg/m3 et une épaisseur comprise entre 4 et 40 mm et, de préférence, comprise entre 8 et 12 mm.The nonwoven fabric used according to the invention is produced by the dry process. It has a density of between 20 and 100 kg / m 3 and preferably between 30 and 60 kg / m 3 and a thickness of between 4 and 40 mm and preferably between 8 and 12 mm.
L'étoffe non tissée mise en oeuvre selon l'invention comporte au minimum 50% de fibres synthétiques, de préférence choisies parmi les fibres de polyester, de polyamide, de polyoxyamide, ou les fibres du type "superabsorbant" ou un mélange de ces différentes fibres. Par fibres du type "superabsorbant", on entend des fibres ayant une capacité d'absorption supérieure à 100% c'est-à-dire des fibres absorbant plus d'1 g d'eau par gramme de fibre. Les fibres "superabsorbantes" utilisées sont, par exemple, celles commercialisées sous les noms Lansael®, Fibersorb@ ou Bemliese®.The nonwoven fabric used according to the invention comprises at least 50% of synthetic fibers, preferably chosen from polyester, polyamide, polyoxyamide fibers, or fibers of the "superabsorbent" type or a mixture of these different fibers. The term "superabsorbent" type fibers means fibers having an absorption capacity greater than 100%, that is to say fibers absorbing more than 1 g of water per gram of fiber. The "superabsorbent" fibers used are, for example, those sold under the names Lansael®, Fibersorb @ or Bemliese®.
Avantageusement, les fibres synthétiques choisies sont des fibres de polyester. Les fibres utilisées sont, de préférence, hydrophiles ou rendues hydrophiles par un traitement approprié.Advantageously, the synthetic fibers chosen are polyester fibers. The fibers used are preferably hydrophilic or made hydrophilic by an appropriate treatment.
Les fibres synthétiques entrant dans la composition de l'étoffe utilisée suivant l'invention ont une épaisseur comprise entre 3 et 40 dtex et, de préférence, comprise entre 6 et 20 dtex et une longueur comprise entre 2 et 12 cm et, de préférence, comprise entre 5 et 7,5 cm.The synthetic fibers used in the composition of the fabric used according to the invention have a thickness between 3 and 40 dtex and, preferably, between 6 and 20 dtex and a length between 2 and 12 cm and, preferably, between 5 and 7.5 cm.
L'étoffe non tissée utilisée selon l'invention peut comporter jusqu'à 50% de fibres naturelles et/ou artificielles qui peuvent être, par exemple, des fibres de cellulose (coton, rayonne, viscose) ou de laine.The nonwoven fabric used according to the invention can comprise up to 50% of natural and / or artificial fibers which can be, for example, cellulose fibers (cotton, rayon, viscose) or wool.
Les fibres composant l'étoffe mise en oeuvre suivant l'invention sont liées par aiguilletage.The fibers making up the fabric used according to the invention are bonded by needling.
Dans une forme particulière d'exécution de l'invention, lesdites fibres sont liées à la fois par aiguilletage et par liage thermique. Dans ce cas, l'étoffe non tissée doit contenir un certain pourcentage de fibres "thermoliantes".In a particular embodiment of the invention, said fibers are linked both by needling and by thermal bonding. In this case, the nonwoven fabric must contain a certain percentage of thermo fibers. binders ".
On entend par fibres thermoliantes des fibres dont le point de fusion est inférieur à celui des fibres principales, ou des fibres ayant une couche superficielle dont le point de fusion est inférieur à celui de la partie intérieure de la fibre (fibrea "bicomposantes").By thermobonding fibers is meant fibers whose melting point is lower than that of the main fibers, or fibers having a surface layer whose melting point is lower than that of the inner part of the fiber ("two-component" fibrea).
Dans une autre forme de réalisation de l'invention, les fibres sont liées à la fois par aiguilletage et par liage chimique. Ce liage chimique est réalisé par aspersion des fibres avec une résine qui peut être, par exemple, une émulsion aqueuse de résine de polyacrylate ou de polyuréthane.In another embodiment of the invention, the fibers are linked both by needling and by chemical bonding. This chemical bonding is carried out by spraying the fibers with a resin which can be, for example, an aqueous emulsion of polyacrylate or polyurethane resin.
L'étoffe non tissue utilisée suivant l'invention possède une résistance à la compression suffisante pour que, lorsqu'elle est soumise à une pression statique de 20 cN/cm2 (ce qui correspond à la pression exercée par le poids d'une personne moyenne), elle conserve une épaisseur minimale de 2 mm. Avantageusement, cette épaisseur minimale est de 4 mm.The nonwoven fabric used according to the invention has sufficient compressive strength so that, when subjected to a static pressure of 20 cN / cm 2 (which corresponds to the pressure exerted by the weight of a person medium), it retains a minimum thickness of 2 mm. Advantageously, this minimum thickness is 4 mm.
Cette épaisseur minimale de 2 mm, voire 4 mm, est nécessaire pour permettre à l'étoffe d'absorber la transpiration émise par l'utilisateur du siège, et pour permettre à l'étoffe de transporter cette humidité dans une direction parallèle à la surface de l'étoffe, ou de la transporter par ventilation.This minimum thickness of 2 mm or even 4 mm is necessary to allow the fabric to absorb the perspiration emitted by the seat user, and to allow the fabric to transport this moisture in a direction parallel to the surface. fabric, or transport it by ventilation.
L'invention a également pour objet un revêtement de sièges destinés au transport de personnes, comportant un tissu de recouvrement et une étoffe non tissée, cette étoffe ayant les caractéristiques énumérées ci-dessus.The subject of the invention is also a covering of seats intended for the transport of persons, comprising a covering fabric and a nonwoven fabric, this fabric having the characteristics listed above.
Dans une autre forme de réalisation du revêtement suivant l'invention, le tissu de recouvrement et l'étoffe non tissée peuvent être contrecollés par une des techniques connues de l'homme de métier. Ce contrecollage peut, parexemple, être réalisé à l'aide d'un moyen d'encollage tel qu'une dispersion, une émulsion ou une solution de colle ou tel qu'une poudre, un film ou un enduit thermoplastique. Ce moyen d'encollage peut être appliqué, par exemple, par pulvérisation, saupoudrage, imprégnation ou impression.In another embodiment of the covering according to the invention, the covering fabric and the nonwoven fabric can be laminated by one of the techniques known to those skilled in the art. This lamination can, for example, be carried out using a sizing means such as a dispersion, an emulsion or an adhesive solution or such as a powder, a film or a thermoplastic coating. This sizing means can be applied, for example, by spraying, dusting, impregnation or printing.
La présente invention a encore pour objet une matière de revêtement de sièges destinés au transport de personnes, consistant en un tissu de recouvrement contrecollé à une étoffe non tissée; cette étoffe ayant les caractéristiques énumérées ci-dessus. Le contrecollage peut être effectué selon l'une des techniques connues de l'homme de métier et énumérées précédemment.The present invention also relates to a covering material for seats intended for the transport of persons, consisting of a covering fabric laminated to a nonwoven fabric; this fabric having the characteristics listed above. The laminating can be carried out according to one of the techniques known to those skilled in the art and listed above.
De plus, l'invention a pour objet un siège destiné au transport de personnes (par route, rail ou air), possédant un revêtement ou une matière de revêtement suivant l'invention.In addition, the invention relates to a seat intended for the transport of persons (by road, rail or air), having a covering or a covering material according to the invention.
Des caractéristiques supplémentaires de l'invention apparaîtront encore au cours de la description des exemples de réalisation de l'invention, ces exemples n'étant nullement limitatifs.Additional characteristics of the invention will become apparent during the description of the exemplary embodiments of the invention, these examples being in no way limiting.
L'étoffe non tissée mise en oeuvre suivant l'invention comporte deux types de fibres qui sont présentés en mélange sous la référence "D-291 Quallofil®" de la société Dupont de Nemours. Il s'agit d'un mélange de fibres thermoliantes et de fibres de polyester de 13 dtex, creuses, à quatre canaux, le pourcentage de volume creux étant supérieur à 23% du volume total de la fibre. La longueur des fibres est de 7 à 8 cm. Une finition particulière procure à cette fibre une surface lisse, hydrophile et un caractère d'inflammabilité réduit.The nonwoven fabric used according to the invention comprises two types of fibers which are presented as a mixture under the reference "D-291 Quallofil®" from the company Dupont de Nemours. It is a mixture of thermobonding fibers and polyester fibers of 13 dtex, hollow, with four channels, the percentage of hollow volume being greater than 23% of the total volume of the fiber. The length of the fibers is 7 to 8 cm. A special finish gives this fiber a smooth, hydrophilic surface and a reduced flammability character.
Le mélange de fibres a été cardé et nappé selon les techniques bien connues de l'homme de métier. Les fibres ont alors été liées par aiguilletage puis par liage thermique.The fiber mixture was carded and coated using techniques well known to those skilled in the art. The fibers were then bonded by needling and then by thermal bonding.
L'étoffe ainsi obtenue a une épaisseur de 10 mm et une densité apparente de 40 kg/m3. Elle présente une résistance à la compression telle que, lorsqu'elle est soumise à une pression statique de 20 cN/cm2, cette étoffe conserve une épaisseur de 8,5 mm.The fabric thus obtained has a thickness of 10 mm and an apparent density of 40 kg / m 3 . It has a compressive strength such that, when subjected to a static pressure of 20 cN / cm 2 , this fabric retains a thickness of 8.5 mm.
Cette étoffe non tissée a été testée, en comparaison avec une mousse standard sur un "modèle-peau" selon la norme DIN 504-101 Teil 1. Cette norme est par ailleurs proposée comme projet de norme sous la référence ISO/TC 38/SC 8 H 156.This nonwoven fabric has been tested, in comparison with a standard foam on a "skin model" according to DIN 504-101 Teil 1. This standard is also proposed as a draft standard under the reference ISO / TC 38 / SC 8:15 a.m.
Les paramètres testés sont les suivants : la résistance thermique : Rct (mesurée en m2 K/w), la résistance au transport d'humidité : Ret (mesurée en m2 mbar/w) et la capacité d'absorption de l'humidité Fi (exprimée en %) (poids d'eau absorbée par poids sec de produit). Ces trois paramètres ont été mesurés en conditions statiques, c'est-à-dire en soumettant l'étoffe non tissée ou la mousse à une charge statique de 20 cN/cm2. Les trois paramètres ont également été mesurés en conditions dynamiques, c'est-à-dire en soumettant l'étoffe non tissée ou la mousse à des impulsions de 20 cN/cm2, 2 fois par seconde.The parameters tested are as follows: thermal resistance: Rct (measured in m 2 K / w), resistance to moisture transport: R and (measured in m 2 mbar / w) and the absorption capacity of the humidity Fi (expressed in%) (weight of water absorbed per dry weight of product). These three parameters were measured under static conditions, that is to say by subjecting the nonwoven fabric or the foam to a static load of 20 cN / cm 2 . The three parameters were also measured under dynamic conditions, that is to say by subjecting the nonwoven fabric or the foam to pulses of 20 cN / cm 2 , 2 times per second.
Le quatrième paramètre mesuré est la vitesse de ventilation : V exprimée en % et répondant à la formule suivante :
Les résultats de ces tests comparatifs sont rassemblés dans les tableaux suivants :
- - conditions statiques :
- - conditions dynamiques :
- - static conditions:
- - dynamic conditions:
On peut conclure de ces tableaux que, bien qu'ayant une résistance thermique légèrement supérieure, l'étoffe non tissée possède une plus faible résistance au transport de l'humidité et une meilleure capacité d'absorption de l'humidité que la couche de mousse.It can be concluded from these tables that, although having a slightly higher thermal resistance, the nonwoven fabric has a lower resistance to moisture transport and a better capacity for absorbing moisture than the foam layer. .
La vitesse de ventilation s'élève pour l'étoffe non tissée à 32% ((1,279-0,867)/1,279) et pour la couche de mousse à 23% ((1,715-1,318)/1,715); ce qui signifie que l'effet des vibrations et des mouvements apporte une augmentation plus importante du transfert d'humidité dans le cas de l'étoffe non tissée que dans le cas de la couche de mousse.The ventilation speed is 32% ((1.279-0.867) / 1.279) for the nonwoven fabric and 23% ((1.715-1.318) / 1.715) for the foam layer; which means that the effect of vibrations and movements provides a greater increase in the transfer of moisture in the case of the nonwoven fabric than in the case of the foam layer.
