Definitions

  • the invention relates to a process for manufacturing a fusible textile product for clothing use, a fusible textile product produced by carrying out the process and an installation for carrying out the process.
  • the transfer method is more specifically intended for coating textiles with a certain elasticity, which constitute a support for synthetic leather.
  • This process comprises the following successive steps: first, coating a silicone paper or a steel strip - that is to say a support material - with a coating material. This coating is continuous - the coating material forming a film and produced by the known technique of the scraper. Then, the textile to be coated is placed on the support material coated with the material. coating and the assembly is pressed by means of pressure rollers to carry out the transfer.
  • the transfer is carried out by pressing and, consequently, it is likely that at least part of the coating material enters the textile. Furthermore, it should be noted that the review article mentioned above indicates as a method especially intended for the application of a sticky product, the technique of the "inverted coating roller".
  • Patent DE 2363670 describes a process and an installation for printing a textile material with ink.
  • An endless metal transfer belt receives ink through printing cylinders. Then, the ink on the transfer tape is dried. Then the textile material is pressed onto the transfer strip with simultaneous action of heat, this combination of pressing and heat causing the ink to transfer from the metal strip to the textile material.
  • This process therefore has the same drawback as mentioned above, namely the heating of the textile, which limits the range of textiles which can be used.
  • this process is not intended for coating a fusible material whose characteristics are quite different from those of an ink. Thus the use of a metal strip does not allow the transfer of a fusible material.
  • Patent FR 2454334 describes a process for covering a textile strip with a powdered material, by direct coating, without the need for an intermediate transfer strip.
  • the deposition of powdered material is carried out directly on the textile strip previously heated and also subsequently heated so that the material is fixed and stabilized. After this hot deposition, a roller applies a certain pressure to the textile strip.
  • the addition certificate FR 2367136 describes a process for combining a modifying agent on a nonwoven web comprising fusible thermoplastic fibers.
  • the nonwoven web and a sheet coated with the coating agent pass between two heated cylinders forming a pinch, one of the cylinders having reliefs and the other being smooth.
  • This process allows by a single operation and at the place where the cylinders are in contact but nevertheless in distinct zones (respectively the reliefs and the hollows) to ensure on the one hand the connection of the nonwoven and on the other the transfer of the modifying agent.
  • the latter is not a bonding agent, this function and the characteristics which result therefrom being excluded.
  • This certificate of addition therefore refers to pressing and heat to ensure the transfer.
  • Patent FR 2318914 describes a method and a device for applying hot-melt powdered glue to a textile surface, by direct coating, the textile passing over an initial input cylinder where it is heated to 220 ° C., then on an engraving cylinder comprising cavities at an intermediate temperature of 35 ° C and finally on a final outlet cylinder at a temperature of the order of a hundred degrees Celsius.
  • the deposition is carried out by applying the textile to the engraving cylinder by means of the two inlet and outlet cylinders.
  • This method and the device therefore allow the application of an adhesive network. But this application is made thanks to the heat to which the textile is subjected. It follows that the drawbacks mentioned above with regard to the sensitivity of the textile to heat are not moreover overcome by this patent. In addition, due to the method used, there is obviously penetration of the adhesive into the very thickness of the textile.
  • the object of the invention is to produce a fusible textile product for clothing use which has, in combination, the following two characteristics: on the one hand, the fusible material remains on the surface of the textile substrate of the product, ie does not not penetrate into its thickness; on the other hand, the textile substrate used can - without this being necessary - be of a very heat-sensitive type, without being damaged during the manufacturing process.
  • the fusible material is distributed in points scattered on the external face of the textile substrate.
  • the invention therefore first proposes a method of manufacturing a heat-bonding textile product for clothing use and consisting of a textile substrate comprising on one of its external faces of the heat-bonding material, transfer process consisting in first depositing on a transfer support said thermobonding material and then to transfer the thermobonding material from the transfer support on the substrate, the method being characterized by the improvements consisting of the following successive stages: first depositing on the transfer support at least partially non-sticking drops of a pasty dispersion of fusible material. Then, the drops thus initially deposited on the transfer support are heated in order to ensure the drying of the dispersion deposited and the melting of the fusible material which constitutes it.
  • the drops thus dried being placed on the transfer support and the textile substrate are brought into contact, without heating said textile substrate, the fusible material. being transferred from the transfer support to the textile substrate, in the form of points, without however penetrating inside the substrate owing, on the one hand, to the fact that the fusible material adheres more to the textile substrate than to the transfer support and, d On the other hand, only make contact of the heat-bonding material with the textile substrate rather than pressing the transfer support on the textile substrate.
  • the invention also proposes, next, an installation for implementing this method which comprises first means for driving the textile substrate and second means for driving a transfer support, at least partially non-stick as well as , from upstream to downstream and arranged successively, means for depositing drops of a pasty dispersion of fusible material, means for heating the drops thus deposited, and means for transferring the drops thus dried from the transfer support onto the textile substrate.
  • the textile substrate is not heated during the transfer or, moreover, before or after the transfer, which makes it possible to use any type of desired textile substrate.
  • the transfer is not carried out by pressing, but only by contact of the fusible material with the textile substrate, the transfer support remaining spaced from the textile substrate during of the transfer.
  • the invention relates to a method and an installation for manufacturing a fusible textile product 1 for clothing use, consisting of a textile substrate 2 comprising on one of its external faces 3 of the fusible material.
  • the heat-bonding material is distributed on the textile substrate 2 at points 4 dispersed on the corresponding external face 3.
  • points is meant individualized zones, that is to say unconstrained zones, as opposed to a continuous film in particular and most generally of general shape at least pseudo circular resembling the outline of a drop.
  • the expression “point” also covers a more or less extensive linear or surface shape, rectilinear, etc., always in opposition to a continuous shape.
  • the invention also relates to such a fusible textile product 1 produced by the process or by means of the installation according to the invention.
  • the textile product 1 according to the invention has the characteristics on the one hand that the textile substrate 2 can be of a very heat-sensitive type and, on the other hand, that the fusible material remains on the surface of the textile substrate 2 without penetrating inside, in the thickness of the textile substrate 2, regardless of the nature of the textile used.
  • the textile substrate 2 is arbitrary, depending on the desired application, for example composed of yarns based on natural or synthetic fibers that are not very sensitive to heat (polyester, polyamide 6-6, polyethylene) or very thermally fragile (polyamide 6, polypropylene, acrylate, PVC type "Rhovyl” (registered trademark).
  • This substrate is generally in the form of a sheet or transversely deformable strip, in particular being able to be wound on itself or on a cylinder or roller.
  • the fusible material is applied to the sheet but does not penetrate inside, perpendicularly.
  • FIG. 3 a point of fusible material which is applied to a textile substrate 2 by one of the traditional methods. It can be seen that point 5 has an external part 5a disposed on the face 3 of the substrate and a part 5b which has diffused inside the textile material fibers forming the substrate 2. This part 5b makes the textile product less flexible and decreases the useful quantity of fusible material constituted by the external part 5a.
  • the points 4 do not penetrate into the textile substrate 2, - that is to say remain entirely in relief on the face 3 - and the textile product retains its original flexibility while being effective from the point in terms of bonding, the fusible material not being "lost" in the thickness of the textile substrate 2.
  • the fusible material per se is not directly the subject of the invention. They are copolyamide and / or thermoplastic copolyester and / or chemical derivatives of one or both, alone or in combination with other thermoplastic copolymers, thermosetting in aqueous and / or alcoholic dispersion and / or other polar solvent, originally present at room temperature in the form of a paste.
  • the process according to the invention is of the transfer type, that is to say that the heat-bonding material is first deposited on a transfer support 6 and then the heat-bonding material is transferred from the transfer support 6 to the substrate 2.
  • the method according to the invention is characterized by the improvements consisting of the following successive steps: firstly drops on the transfer support 6 at least partially non-sticking drops 7 of a dispersion of fusible material. Then we heat the drops as well initially deposited on the transfer support 6 in order to ensure the drying of the dispersion deposited and the melting of the fusible material which constitutes it.
  • the drops thus dried on the transfer support 6 and the textile substrate 2 are then brought into contact without heating said textile substrate 2, the fusible material being transferred from the transfer support 6 to the textile substrate 2, in the form of points, without however penetrating inside the substrate 2 because, on the one hand, that the fusible material adheres more to the textile substrate 2 than to the transfer support 6 and, on the other hand, that only a contact of the fusible material with the textile substrate 2 rather than pressing the transfer support 6 on the textile substrate 2.
  • the expression “drop” refers more particularly to the case of a circular point deposit. However, the expression drop also covers, within the meaning of the present invention, a deposit which is more or less linear or surface.
  • the transfer support 6 is moved on which the drops 7 of dispersion of fusible material have been deposited and dried in synchronism and side by side with the textile substrate 2 and this in a transfer zone from a zone of convergence this transfer zone being able to carry out the transfer of the drops.
  • the term “convergence zone” means the zone where the support 6 and the substrate 2 are brought close to each other, this zone being punctual or, at least, of limited length.
  • the term “transfer zone” is understood to mean a zone of more extended length from the convergence zone and downstream where the transfer is actually carried out.
  • the transfer support 6 is kept apart in parallel and without direct contact with the textile substrate 2 and the spacing between them is adjusted according to the thickness of the drops deposited, in order, simultaneously, to ensure the transfer while avoiding the penetration of the textile substrate 2 with the fusible material.
  • the mattness of the dots of fusible material on the textile substrate 2 is adjusted as a function of the dullness of the transfer support 6. Indeed, depending on the dullness of the support 6, dots 4 or glossy dots are obtained. Thus by adjusting the mattness of the support 6, one obtains more or less matt points 4. When the support 6 is shiny, the points 4 are shiny. Indeed, a non-stick support 6 is shiny when it is smooth and without roughness. When liquid drops 7 are deposited on such a support, the surface of the solid drops after cooling is smooth. On the contrary, a non-stick support 6 is matt when it has asperities and these are found on the external surfaces of the solid drops after cooling.
  • the deposition on the transfer support 6 is preferably carried out by screen printing or heliography rather than by scraping, the deposition technique not being, per se, the object of the present invention.
  • the transfer support 6 is preferably constituted by a mat of glass fabrics coated with a non-stick product, in particular based on polytetrafluorethylene or silicone.
  • a non-stick transfer support 6 rather than a simple metal or paper strip only, as is the case in the prior art, is one of the conditions favoring the transfer of the fusible material from the support. 6 on the substrate 2 by contact and not by pressing.
  • Transfer by contact is understood to mean a transfer of the heat-bonding material by means of a transfer support 6 and by contact of said heat-bonding material with the textile substrate 2 but without direct contact between the textile substrate 2 and the transfer support 6 This therefore explains the adjustment of the spacing between the substrate 2 and the support 6, at most to the thickness of the drops deposited and dried, as mentioned previously (with compensations for the thicknesses of the substrate 2 and support 6 close).
  • the substrate textile 2 is not heated, that is to say that it is at ambient temperature, having moreover not been previously heated.
  • the textile substrate 2 is not further heated and, if necessary, the dots 4 of fusible material on the textile substrate 2 are cooled (and consequently the substrate 2 itself, in general) and this in order to solidify them. Indeed, this solidification is not yet achieved since the transfer (convergence zone) occurs immediately or shortly after the drying of the drops 7 and the melting of the polymer or polymers making up said drops 7.
  • an additional heat supply is made in the convergence zone.
  • Such a supply of heat aims to facilitate, as far as necessary, the transfer.
  • this heat supply cannot be substituted for the prior heat supply relating to the drops 7 and is not aimed at their drying.
  • it if such an addition of heat is desired, it relates more to the drops 7 (possibly the transfer medium 6 consequently) than to the textile substrate 2.
  • such additional heating is only necessary to keep in fusion the fusible polymers with high melting point and high viscosity in the molten state.
  • An installation for implementing the method comprises first drive means 15 for the textile substrate 2 and second drive means 12 for a transfer support 6, at least partially non-stick as well as from upstream to downstream and arranged successively, means 8, 10 for depositing drops of a dispersion of fusible material on the support 6, heating means 14 for the drops thus deposited, and transfer means 12, 15, 16, 17 for the drops as well dried from the transfer medium on the textile substrate 2.
  • the drop transfer means consist of the first and second drive means 12, 15 arranged to operate in synchronism and of calendering cylinders or the like 16, 17 slightly spaced transversely so as to also maintain the transfer support 6 and the textile substrate 2 apart and without direct contact with each other, the spacing between them being adjusted as a function of the thickness of the drops deposited (and of the thickness of the substrate 2 and of the support 6) in particular by adjustment means acting on the calendering cylinders 16, 17.
  • the transfer means 12, 15, 16, 17 are devoid of means for direct reciprocal pressure of the textile substrate 2 and of the transfer support 6 in order to ensure their intimate contact.
  • the transfer means 12, 15, 16, 17 provide a transfer zone of a certain length capable of allowing the transfer of the drops.
  • the transfer zone is devoid of means for heating the textile substrate 2.
  • the first drive means 15 are constituted for example by one of the calendering cylinders 16, 17 belonging to the transfer means, this calendering cylinder being driven in rotation by drive means such as a motor.
  • the second drive means 12 are constituted, for example, by a drive cylinder placed downstream of the device, in particular after the calendering cylinders 16, 17 and at the end of the transfer zone.
  • the means 8, 10 for depositing drops, in the pasty state on the non-stick transfer support 6 comprise, for example a cylinder 8 of rotogravure or serigraphy of axis 9 and a full counterpart cylinder 10, opposite , of axis 11 parallel, the two cylinders 8, 10 being in contact on either side of the transfer support 6.
  • These two cylinders 8, 10 are placed essentially upstream of the device and rotate in opposite directions by means such as an engine.
  • This motor is associated with the motor of the drive means 12 so that, upstream and downstream, the transfer support 6 moves at the same linear speed.
  • the heating means 14 can be the subject of numerous variant embodiments. These are essentially means for heating the drops 7 by radiation (for example by infrared or microwave) or even by convection (hot air) rather than by conduction and this taking into account that the transfer support 6 is, in itself, normally little or poorly conductive of heat.
  • the heating means 14 are of variable intensity (over their length) and extend over a length (therefore, taking into account the speed of travel of the transfer support 6 are active for a corresponding duration) such as the drops 7 deposited by the cylinders 8, 10 are successively dried then the polymer which constitutes the fusible material is at least partially molten. It should be observed that the heating means 14 are normally placed on a linear path of the transfer support 6 between the deposition cylinders 8, 10 and the calendering cylinders 16, 17. This arrangement makes it possible to distribute the heating means 14 over the desired path length, without jeopardizing the architecture of the device, this which would not be the case if the heating means were integrated into a cylinder, the length of the path then being fixed and limited.
  • the heating means 14 are placed downstream, generally near the deposition cylinders 8, 10, in order to avoid too great a bulk of the installation. In general, they are placed upstream of the calendering cylinders 16, 17, close enough to them so that the fusible polymers are still in fusion in the convergence zone while being arranged so as not to unduly heat the textile substrate 2 arriving on the calendering cylinder 16.
  • the calendering cylinders 16, 17 define the convergence zone. These two cylinders are in particular identical, of the same radius, smooth, with parallel axes, driven in opposite directions in synchronism. They are slightly separated transversely from each other, that is to say that they are not tangent, of course, but that their generatrices opposite, the closest, are separated from each other and not in contact, this spacing being adjusted as a function of the thickness of the drops deposited by the deposition cylinders 8, 10. In particular this spacing is such that it is at most equal to the thickness of the drops, to the thicknesses of the substrate 2 and support 6 close.
  • the axes of the calendering cylinders 16, 17 can be carried by two pairs of reciprocal adjustable spacing bearings. Adjustment means such as worms or the like make it possible to adjust this spacing. Locking means such as nuts or the like allow this fixed spacing to be maintained.
  • the adjustment means generally comprise means for identifying the value of the spacing.
  • Return or deflection cylinders or the like make it possible to define the end of the transfer zone and the start of the divergence zone of the textile substrate 2 and of the transfer support 6.
  • the return cylinders are arranged in a similar manner to the return cylinders.
  • calendering 16, 17 so as to be apart in a comparable manner to the calendering cylinders 16, 17.
  • the calendering cylinders 16, 17 and the cylinders of reference are axially spaced apart by a length defining the length of the transfer zone. This length is adjustable, if necessary, the bearings of the calendering and deflection cylinders being arranged accordingly. In all cases, this length is such that the heat-bonding polymer has time to recrystallize so that at the end of the transfer zone the drops 7 are fully transferred from the support 6 to the substrate 2.
  • light and reciprocal pressure means are associated with the calendering cylinders 16, 17, respectively with the return cylinders with the sole function of ensuring the maintenance of the desired spacing between the substrate 2 and the support 6 and therefore the quality of the transfer.
  • the light pressure means therefore essentially aim to ensure that the substrate 2 and the support 6 are properly applied to their respective calendering cylinder.
  • pressure means are not intended to ensure direct contact with pressure between the calendering or return cylinders respectively, such direct contact with pressure in front, on the contrary , be avoided.
  • additional heating means are also provided located at the upstream limit of the convergence zone, intended to essentially heat the drops 7.
  • additional heating cannot replace the heating means 14 and do not have the same function as the heating means 14.
  • additional heating means are only necessary to keep the polymers in fusion until the time of transfer. This variant is only useful for polymers with a high melting point and high viscosity in the molten state.
  • the textile substrate 2 and the transfer support 6 are separated from one another by means of deflection cylinder or the like.
  • the textile substrate comprising the dots 4 of heat-bonding material is, for example, wound in a reel 18 downstream of the transfer zone.
  • the installation also includes, and possibly, means capable of cooling the dots 4 of fusible material once transferred onto the textile substrate 2, located in the transfer zone downstream from the convergence zone.
  • these means are constituted by the unheated ambient air in which the substrate 2 circulates with the points 4 of fusible material.
  • these means are effective means of cooling by production of cold, such as cooling plates in which a cooling fluid circulates, plates which are in direct contact with the transfer support and located opposite the textile substrate 2; or such as a cooling box in the walls of which circulates a cooling liquid in order to maintain an atmosphere in said box such that the textile support assembly 2, heat-bonding points 7 and non-stick support 6 are placed at low temperature and protected from any unwanted condensation moisture.
  • these means are placed upstream of the spool 18 so that the textile 1 is only spooled once the product is transferred perfectly stable.
  • the installation does not include means for heating the textile substrate 2 before the transfer.
  • the calendering cylinder 16 on which the textile substrate 2 is located is not heated, and according to a variant of the invention, can be cooled by circulation of coolant in order to freeze the molten polymer as soon as it comes into contact with textile 2.
  • the installation operates discontinuously, the transfer support 6 extending between an upstream storage coil 13 placed upstream of the deposition cylinders 8, 10 and a downstream storage coil placed downstream of the return cylinders, in particular in the region of the reel of fusible textile product 19.

  • Under the roller 21 is placed a brush 23 which makes it possible to clean the surface of the transfer support 6 from the particles of dots or drops which could remain there.
  • the transfer support 6 and the textile substrate 2 are, in the main part of the installation tensioned and driven in synchronism, in particular continuously at constant speed. In the convergence zone where the substrate 2 and the support 6 are opposite, they are spaced apart and parallel to each other, only the drops 7 previously heated ensuring contact between them, the transfer being carried out due to greater relative adhesion of the fusible material with the substrate 2 than with the non-stick support 6.
