Definitions
- the present invention relates to a improved process for manufacturing textile products from "topped-glued" type directly from fibers and / or filaments.
- the invention also relates to a device for the implementation of the process, as well as the products obtained by said process.
- the so-called "coated-glued” products are products which are made from a textile tablecloth, and preferably from a sheet already made up of threads, or possibly from a fibrous web, which is subjected to a succession of folds in order to form folds which can be assimilated in the direction of advance from tablecloth to curls.
- This folded tablecloth is then simply attached to a support by gluing. We obtain thus a product where the threads and / or fibers do not pass through the support, unlike tufted products, which are in the form of a succession of loops crossing the support.
- the first family is the best known and understands processes using a hand-held machine which are fixed blades. A sheet of thread is pushed by these blades successively on a first folder and then on a second folder which is parallel to the first in order to form by folding a succession of loops. Then, these loops are secured to a support, which is preferably previously coated with a glue such as polyvinyl chloride plastisol, on which loops will be dropped, the whole as well constituted by the support and the integral loops being then subjected to a heat treatment, for example a passage through an infrared oven.
- a glue such as polyvinyl chloride plastisol
- the loops can be held between two front supports that a hot melt adhesive does not pass through said supports in order to impregnate the bases of the loops.
- Another alternative is to offer the use of stretched cables to replace the blades mentioned above.
- successive folds are formed by means of a rotary system, pushing the threads and / or fibers of the sheet successively in growths present on a grooved cylinder.
- the folds are created under the action of a folding organ like a blade or a roller themselves grooved.
- a support preferably beforehand coated with glue, placed on the succession of loops obtained by folding.
- the whole support / integral loops is subjected to a treatment before they are removed from the grooved cylinder.
- the technique described consists in subjecting fibers and / or filaments "transverse looping” accompanied by a “stretching” and to obtain an accumulation of fibers and / or filaments in the form of a wavy “pseudo-thread" in which the fibers and / or filaments are parallelized.
- This step is generally called “step of (pre) looping "and should not be equated with folding.
- each fiber or filament is in principle involved in at least one loop.
- the pseudo-wire is then transported using of these transport components constituted either by the needles, either by the transfer elements, in the form transverse rows of loops, to a support to which the loops are joined.
- the first set is intended for perform a ripple step using a device constituted by the interpenetration of a first set of inverter discs with a first set of inverter fingers
- the second set is intended to achieve the classic subsequent step called the pre-closing step at using a device made up of interpenetration a second set of discs called looping discs with a second set of fingers called looping fingers, this second assembly being arranged downstream of the corrugation device relative to the direction of advance of the veil.
- the gauge of ripple device is a multiple of the gauge of the pre-loop device.
- the products offered in this document are mainly in the form of products tufted.
- the production speed which can express themselves as the product of the advance by stroke of the substrate (in mm) by the beat rate of the needles (in strokes per minute) reaches an order of magnitude of 1.5 to 4.5 m / min, which is entirely admissible to achieve tufted products but is still too weak in the case of a production comparable to a line needling, the production speed of which can reach an order of 15 m / min.
- the gauge of a so-called verticalization device may hardly be less than 1/10 inch, or 2.54 mm, unless it allows the realization of very precise and therefore relatively expensive, and which would deprive the so-called verticalization process of possibility of making inexpensive products.
- the present invention aims to provide a solution to existing limitations, and more particularly with regard to productivity, in the processes used in the technique known as verticalization as described in the documents WO91 / 00382 and WO96 / 10667.
- the present invention aims more particularly to allow the realization of products so-called "coated-glued” which may have a similar appearance of those known in the state of the art while allowing a very high productivity during the implementation process work.
- the present invention aims as complementary to allow the realization of products of type "coated-glued" fine gauge, that is to say having a gauge less than 1/10 of an inch.
- the present invention aims to allow the realization of new products that were currently impossible to achieve using the technique described as is in publications of the Applicant, and more particularly in publications WO91 / 00382 and WO96 / 10667.
- the present invention relates to a process for producing a textile product of the "topped-glued" type from fibers and / or filaments flowing in the direction of advance in the form of a veil, this process comprising at least one step called the pre-looping step in which the fibers and / or filaments undergo individually looped transversely to advance management, possibly accompanied by a transverse stretching.
- the transverse looping accompanied by stretching is carried out for each individual fiber or filament using elements rotary or looper discs spaced apart and arranged on a transverse axis with respect to the direction of advance of the veil and between which are arranged looping fingers. This allows each fiber or filament to be involved in at least one pre-loop step and allows the parallelization of these fibers and / or filaments elementary.
- the present process is characterized by that we carry out a confinement of the material under form of loops formed by fibers and / or filaments particularly well parallelized and that this confinement is produced directly on a support without there intervention of transport devices such as needles or transfer elements.
- This confinement is obtained after a first transitional stage linked to the start of a product line and during which the first loops obtained by the pre-looping step of the fibers and / or filaments individual randomly form a stop.
- the containment comes in the form of an accumulation of loops, made up of fibers and / or filaments one behind the other.
- the positioning of successive loops takes place essentially vertically using a detaching element, which guides the material to the support while holding it by tie-down.
- the support can be directly the substrate end of the product we want to make, and in fact consisting of a fiber mat, a plastic film, a PVC type backing, ....
- the material confined could be seized by an intermediate element such as a spiked mat, a brush, or a stand velcro ®, whose role is to maintain the wavy shape loops while the free end of the material is secured to a substrate.
- an intermediate element such as a spiked mat, a brush, or a stand velcro ®, whose role is to maintain the wavy shape loops while the free end of the material is secured to a substrate.
- This attachment to the substrate is done at using an adhesive whose viscosity is designed to allow a drive of fibers and / or filaments material with the substrate while performing an effective bonding.
- plastisols i.e. resins (acrylics, isocyanates, styrene-butanian, phenolic, etc.), or thermoplastics in the form of hot melt, film or powder (polyesters, polypropylene, EVA PVC, etc.), i.e. foams (PVC, acrylics, etc.), either by performing a direct adhesion by fusion of the verticalized fiber on the substrate.
- the means used to provide calories necessary for this are preferably brought by an oven infrared, a calender or a heating drum or heating blades which are in the form of flat metal parts with resistors electrical or heat transfer fluid conduits.
- the substrate feed rate can either be uniform, or be done in spurts, so that we obtain a containment of the textile material more marked on this support.
- This device essentially includes a game of discs called “looping discs” marked 11 and carried on a transverse common axis 13 driven in continuous rotation at a peripheral speed preferably equal to the speed of entry of the web 0.
- the discs looper 11 are provided on their periphery with a toothing 15 having an appropriate angle to the tangent and which allows the training of the entry veil. Between each of the discs are arranged with sulking fingers 21 the end of which is essentially so tangential to the discs.
- This device allows to carry out the so-called “pre-looping step”, which consists in subjecting the fibers and / or filaments individually a transverse looping accompanied by a stretching, in order to parallelize them correctly.
- FIG. 2a describes the step in which the veil 0 consisting of fibers and / or individual 10 filaments have just been introduced between looping discs 11 and looping fingers 21.
- the fibers and / or filaments 10 individually undergo the step of pre-loop already described and which corresponds to a loop individual transversal possibly accompanied by drawing.
- the fibers and / or filaments 10 parallelized are brought to the fingertips looper 21.
- Figure 2b shows that the fibers and / or filaments 10 which continue to be entrained by the rotating looper discs 11 are next blocked by the presence of detaching feet 31 against which they start to accumulate behind each others in order to form a stop (or "plug") 20.
- the fibers and / or filaments are strongly inclined and can even appear, at the limit, almost horizontal.
- Figure 2c shows that this stop or "plug" 20 tends to expand downward direction of a substrate 100.
- FIG. 2d shows that the "plug" 20 consisting of the accumulation of fibers and / or filaments parallelized and wavy ends up reaching such a volume that it comes into contact naturally with the substrate 100 placed just under the looping fingers 21.
- the fibers and / or filaments originating directly from the pre-loop stage condense during a step called “containment step", this time vertically, against the obstacle constituted by the "plug".
- Figure 2e shows that the "plug" 20 is driven by substrate 100, aided in this by rotation looping discs 11 and by the pressure exerted by the fibers and / or filaments 10 parallelized which continue to come from looping fingers 21.
- This phase shows that the fibers and / or filaments are then deposited regularly on the substrate 100 without there being any more of accumulation in the form of a "plug". In this case, these fibers and / or filaments are arranged so essentially vertical.
- the detaching feet 31 prefferably have a particular form to facilitate this step.
- the detaching feet are arranged so that they can be made a funnel 41 between said feet and the substrate 100 which continues to flow.
- the feet detachers 31 no longer have the function of detaching the fibers and / or filaments of the looping fingers, but rather the function of promoting the joining of said fibers and / or filaments on the substrate.
- the rounded part of detaching feet will also guide the fibers and / or filaments confined to the substrate, while its oblique part, located at a distance from the substrate slightly less than the looping height, will exert a pressure of the fibers and / or filaments parallelized so to force them to adhere to the support.
- the tension present within the fibers and / or filaments by the time they are confined to the feet detachers is less than that prevailing within the material undergoing the pre-looping step, which allows easy training of parallel fibers and / or filaments with the substrate. Indeed, if the tension undergone by fibers and / or filaments at the end of the looping fingers during the pre-loop step was less than the reaction pressure exerted by the "plug" or stop in the funnel formed by the detaching feet 31 and the substrate 100, the fibers and / or filaments 10 would start then to accumulate between the looping discs 11 and the looper fingers 21, and this until the entry of the veil. Of this fact, there would be no automatic training of the material with the substrate.
- This tension mainly depends on the orientation of the fibers and / or filaments in the veil the entrance to the verticalization device.
- the substrate 100 be previously coated with an adhesive whose viscosity has been chosen so as to allow the entrainment of fibers and / or filaments 10 with the substrate while producing a effective bonding.
- Activation devices and methods can be chosen from the devices or processes by contact, such as calenders, heating blades, etc., devices or processes working with hot air such as ovens, forced air devices, etc., or possibly the devices or processes working by irradiating, infrared energy, ....
- Figure 3 shows an embodiment preferred for the implementation of the method according to the present invention with a view to producing coated-glued products of sandwich type.
- This figure shows a disc looper 11 on which a looper finger 21 is superimposed in the extension of which is placed a detaching foot 31.
- a veil 0 of adequately oriented fibers is driven by a succession of looping discs 11.
- a plastisol deposition is carried out using a doctor blade 51 in order to secure the loops made up of fibers and / or filaments from the pre-looping stage and from the step of confinement to the substrate 100. Then, the product obtained is subjected to a heat treatment at using hot plates 54 in order to obtain a plastisol gelation. A second substrate 102 also coated with a plastisol deposited using a doctor blade 52 is then deposited on the product constituted by the first substrate 100 and the loops secured in order to create a sandwich product 60. This sandwich product 60 is again heat treated with plates heaters 56 in order to obtain the gelation of plastisol present on the second substrate 102. Finally, a blade 58 split the sandwich product 60 in two by slitting so to obtain two velvet type products 70 and 80.
- the present invention enables a series of products which it was not possible to obtain in using the methods and / or devices as described in the Applicant's previous requests.
- a first large family includes the floor, wall or automobile coverings.
- the glues used will mainly be plastisols, PVC or acrylic while the substrates can be woven, non-woven or glass mats (in the specific case of the slab).
- low-rise products but high density of flocked type velvet can be also made for gauges less than 1/16 ".
- the adhesives used are preferably thermoplastics.
- the device used for implementing the method according to the present invention does not include any sensitive organ such as needles or transfer elements which perform reciprocating movements. Therefore, we can even use coarse natural fibers.
- the second large family includes upholstery such as seat upholstery, hangings, etc.
- the gauges are particularly weak, of the order of 1/32 ", and the preferably very fine fibers used. The use of microfibers is even possible.
- the third large family relates to technical textiles which have a structure in form sandwich and which are therefore not split.
- geotextiles that can be used as a structure draining or as a structure with inclusion of powders bentonite type.
- figure 4 describes how to produce a product more precisely composite geotextile with inclusion of clay powder bentonite type.
- a device is introduced into this device veil made in the present case of fibers of a title high, for example greater than 80 dtex, possibly mixed with finer fibers, for example a title of 17 dtex which aim to facilitate the carding the veil.
- the veil 0 is entrained between the succession of discs 11 and pouting fingers 21 with a view to carry out the pre-looping and containment stages as as described in more detail in Figure 2.
- a substrate 104 is brought to the point of stain removal of fibers using a heating blade 61.
- the substrate is preferably made of fibers having a melting point higher than the melting point of the fibers present in the loops from the pre-looping steps and containment.
- This heating blade 61 allows reach a temperature that is higher than the melting temperature of the loops, which by contact adhere directly to substrate 104 in order to obtain a product 60.
- bentonite powder is deposited using conventional means 63 on the product 60 constituted by the substrate secured to the loops.
- the whole then goes on a table vibrating 65 in order to promote the migration of the powder of bentonite- within product 60 to obtain a the most homogeneous distribution possible. This is in particular possible due to high fiber content present in the loops and their resilience important, which prevents them from being crushed under the powder pressure.
- the height of the loops is also chosen according to the weight of the powder to be deposited so to get a space on the top of the product which is free of powder, so that it can be deposit with a second heating blade 67 a second substrate 105.

Description
- leur vitesse de production reste relativement faible. A titre d'exemple, 120 coups par minute est une vitesse déjà relativement élevée pour un système à bras tel que décrit ci-dessus, dû à la complexité du mouvement produit par les organes à cames;
- la quantité d'adhésif nécessaire à solidariser les boucles au support reste importante, et de ce fait, les produits obtenus sont relativement encore trop coûteux;
- la gamme des produits de type "nappé-collé" réalisables est relativement limitée.

Claims (17)
- Procédé de réalisation d'un produit textile de type nappé-collé au départ de fibres et/ou filaments circulant dans la direction d'avance sous la forme d'un voile, ce procédé comprenant au moins une étape appelée "étape de prébouclage" dans laquelle les fibres et/ou filaments subissent individuellement un bouclage transversalement par rapport à la direction d'avance du voile, éventuellement accompagné d'un étirage transversal, caractérisé en ce qu'il comprend ensuite une étape de confinement des fibres et/ou filaments parallélisés sous forme de boucles, cette dernière étape de confinement se produisant à l'aide d'un élément détacheur directement sur un support sans qu'il y ait intervention d'organes de transport tels que des aiguilles ou des éléments de transfert.
- Procédé selon la revendication 1, caractérisé en ce qu'après une première étape transitoire liée au démarrage d'une ligne et au cours de laquelle les premières boucles obtenues suite à l'étape de prébouclage forment de manière aléatoire un arrêt, le confinement s'obtient sous la forme d'une accumulation de boucles les unes derrière les autres et qui se positionnent de manière essentiellement verticale sur ledit support.
- Procédé selon la revendication 2, caractérisé en ce que le positionnement des boucles successives s'effectue également à l'aide d'un élément détacheur qui permet de guider la matière jusqu'au support tout en la maintenant par embarrage.
- Procédé selon l'une quelconque des revendications précédentes, caractérisé en ce que le support est le substrat du produit final.
- Procédé selon l'une quelconque des revendications 1 à 3, caractérisé en ce que le support est un élément intermédiaire tel qu'un tapis à pointes, un brosse ou encore un support Velcro® dont le rôle est de maintenir la forme ondulée des boucles pendant que l'extrémité libre de la matière est solidarisée à un substrat.
- Procédé selon la revendication 4 ou 5, caractérisé en ce que la solidarisation des boucles au substrat se fait à l'aide d'une colle dont la viscosité permet l'entraínement des boucles avec le substrat tout en réalisant un collage efficace.
- Procédé selon la revendication 4 ou 5, caractérisé en ce que la solidarisation des boucles au substrat s'effectue à l'aide de moyens chauffants tels un four, une calandre, un tambour ou une lame chauffante, en vue d'obtenir une adhésion par fusion des boucles au substrat.
- Procédé selon l'une quelconque des revendications précédentes, caractérisé en ce que la vitesse d'avance du support est uniforme ou s'effectue par à-coups.
- Procédé selon l'une quelconque des revendications précédentes, caractérisé en ce que l'on dépose un second substrat sur le produit comprenant le substrat de base et les boucles solidarisées en vue de réaliser un produit sandwich.
- Procédé selon la revendication 9, caractérisé en ce que l'on effectue une refente du produit sandwich en vue d'obtenir deux produits se présentant sous la forme velours.
- Procédé selon la revendication 9, caractérisé en ce que l'on introduit une matière pulvérulente telle de la bentonite, de la craie ou du sable dans la structure sandwich constituée par les deux substrats, accompagnée éventuellement d'éléments solides tels des tuyaux ou des câbles.
- Dispositif pour la mise en oeuvre du procédé selon l'une quelconque des revendications précédentes, comprenant un jeu de disques (11) portés sur un axe commun transversal (13) entraínés en rotation continue et pourvus sur leur périphérie d'une denture (15) présentant un angle par rapport à la tangente et entre lesquels sont disposés des doigts boucleurs (21) dont les extrémités se présentent essentiellement de manière tangentielle par rapport aux disques, caractérisé en ce qu'il présente en outre, dans le prolongement de chaque doigt boucleur (21), un pied détacheur (31).
- Produit obtenu par le procédé selon l'une quelconque des revendications 1 à 11 ou le dispositif selon la revendication 12, caractérisé en ce qu'il comprend un premier substrat sur lequel sont solidarisées des boucles de fibres et/ou filaments parallélisés sans qu'il y ait de traversée des dites boucles dans le substrat, les boucles pouvant éventuellement être tondues lors d'une étape ultérieure, la jauge étant inférieure à 1/10 de pouce et de préférence inférieure à 1/16 pouce.
- Produit selon la revendication 13, caractérisé en ce que la jauge est inférieure à 1/32 de pouce.
- Produit selon la revendication 13 ou 14, caractérisé en ce que les boucles sont solidarisées au substrat soit par fusion, soit à l'aide d'une colle.
- Produit selon l'une quelconque des revendications 13 à 15, caractérisé en ce qu'un second substrat est disposé au-dessus de l'ensemble premier substrat et boucles solidarisées en vue de réaliser une structure sandwich.
- Produit selon la revendication 16, caractérisé en ce qu'il comprend dans la structure sandwich constituée par les deux substrats un matériau pulvérulent tel que de la bentonite enfermé entre les deux substrats.
