Definitions

  • the present invention relates to a process for manufacturing a textile-based fusible product by hot spot coating.
  • Iron-on textile-based products are now commonly used in the clothing industry and allow, for example, the production of linings or reinforcing fabrics which can be heat sealed.
  • a first category of processes consist in the direct application to the textile support of a melt of thermoplastic polymer. It is for example known for the implementation of this process to bring a mass of polymers to a temperature higher than its melting temperature, to distribute it in the cavities of a gravure cylinder (debossed), to scrape the surface of this cylinder and put it in contact with the textile support on which the polymer dots must be applied.
  • this method does not make it possible to obtain a coating by quality points.
  • the action of the scraper does not completely eliminate traces of polymer on the smooth surfaces of the cylinder. Residues of hot polymer remain on these surfaces and come into contact with the textile support.
  • the textile support in contact with the gravure cylinder, loses fibers which adhere to the cylinder, contribute to its fouling and can even remove the scraping of the cylinder which produces a layer of continuous adhesive polymer which is then deposited on the support.
  • the quality of the product obtained is low and ill-suited to its use in the clothing sector.
  • the mass of polymer contained in the cavities, brought into contact with the textile support adheres thereto, which contributes to empty the cavity and to deposit the points on the textile support.
  • Aerated textiles, or with gaps or voids do not ensure uniform adhesion of the polymer contained in all the cavities. Some of them are then not properly emptied, which leads to coating defects.
  • thermoadhesive textile products in which the adhesive is deposited in the form of powder or aqueous solution, in points, on the support. After this deposition, the assembly is brought to a high temperature causing the polymer to melt and adhere to the support.
  • Patent FR 2 586 717 describes a process of this last category in which drops of a dispersion of fusible material are first deposited on a non-stick transfer support, the drops are then heated on the transfer support and then brings the drops of adhesive into contact with the textile substrate.
  • the object of the present invention is a method and an apparatus which simultaneously present the advantages of the "HOT MELT” coating method, in addition to avoiding the grinding of polymers and the advantages of the transfer method, in particular of put the textile in direct contact with the engraved cylinder and avoid bringing the textile support to a high temperature.
  • the method and apparatus of the invention also make it possible to carry out a coating by points having little or no defects, that is to say those whose points are regularly distributed and the support is not adhesive outside the points .
  • a method of manufacturing a textile-based fusible product is proposed by hot spot coating of the type in which a fusible polymer is melted, a gravure cylinder engraved in a hot hollow is filled with said thermoadhesive polymer, the surface of the cylinder scraped.
  • the fusible polymer is deposited in the form of dots on a non-stick transfer mat by the rotogravure cylinder and the dots of fusible polymer are then brought into contact with the support so as to ensure their transfer thereon.
  • this apparatus includes a non-stick mat ensuring the transfer of the fusible polymer dots from the rotogravure cylinder to the textile support and allowing these points to be partially cooled.
  • the method of the invention allows the manufacture of a textile-based fusible product particularly intended for the clothing industry.
  • This type of product has a textile base coated with a heat-bonding polymer.
  • the point coating makes it possible to obtain a quality fusible textile which, during its final use after laminating on another textile, provides the flexibility and touch sought after by manufacturers.
  • a good coating by points requires on the one hand the adhesion of each point of polymer on the support and must make it possible to avoid the deposit of adhesive outside these points.
  • the textile-based fusible product After its manufacture, the textile-based fusible product is stored at room temperature and it is then necessary that the different layers of this product in contact do not adhere to each other.
  • the process of the invention is of the "HOT MELT” type, that is to say that a fusible polymer 1 is melted and then used to fill the cavities 20 of a gravure cylinder 2 engraved in the hollow.
  • the gravure cylinder 2 was directly brought into contact with the textile support 3.
  • the temperature of the coating cylinder 2 is then a compromise. It must be high enough to allow the fusible polymer to be kept in the molten state so that it does not remain in the cavities of the cylinder and must not be too high so as to avoid the crossing of the textile support or even damage. of it.
  • This dissociation simultaneously causes the dissociation of the stresses explained above concerning the temperature of the cylinder 2 and / or of the heat-bonding polymer, distributing these stresses in the two successive phases.
  • the implementation of the method is then greatly facilitated and makes it possible to obtain satisfactory results.
  • the fusible polymer 1 is deposited in the form of dots 4 on a transfer mat 5 partially non-stick, the dots of fusible polymer 4 are then brought into contact with the textile support 3 so as to ensure their transfer to this one.
  • the transfer mat 5 is partially non-stick any surface having this property, that is to say having a low surface tension and coming successively into contact with the gravure gravure cylinder and the textile support. It has a lower adhesiveness for the thermoadhesive material than that of the textile support.
  • its surface is smooth, has neither vacuum nor roughness.
  • It can be flexible, made from a glass fiber or aramid fiber structure covered with a layer of polytetrafluoroethylene (PTFE), or be made from silicone rubber.
  • PTFE polytetrafluoroethylene
  • It can also be rigid, for example consisting of a metal cylinder covered with a layer of polytetrafluoroethylene (PTFE).
  • PTFE polytetrafluoroethylene
  • the thermoplastic polymer 1 is melted. It may for example be a mixture based on polyamides softening between 133 ° C. and 145 ° C.
  • the photogravure cylinder is brought to a relatively high temperature, for example from 230 to 250 ° C. At these temperatures, the thermoplastic polymer has a viscosity of between 14 and 33 MFI (Multi-Flow Index), which makes it possible to fill well and then empty the wells 20 of the gravure gravure cylinder and therefore to achieve a precise distribution of the fusible polymer.
  • MFI Multi-Flow Index
  • the temperature of the gravure cylinder 2 is equal to or greater from 0 to 80 ° C, preferably from 20 to 50 ° C than the melting temperature of the fusible polymer 1.
  • the partially non-stick transfer mat 5 is covered with a layer of silicone or polytetrafluoroethylene (“Teflon"). It easily resists contact with the gravure cylinder 2 and the temperature of the latter is not likely to cause its alteration.
  • Teflon silicone or polytetrafluoroethylene
  • the transfer mat 5 then drives the points of fusible polymer 4 and puts them in contact with the textile support 3.
  • thermoadhesive polymer dots 4 is controlled between the time when they are deposited by the gravure gravure cylinder 2 on the carpet 5 and that when they are brought into contact with the textile support 3. This control of the temperature of the polymer 4 is is naturally obtained; taking into account the ambient temperature and for a given temperature of the gravure cylinder, their temperature on arrival is a function of their transfer time, ie obtained by the use of means 13 during the transfer of points 4.
  • the means 13 for controlling the temperature of points 4 may include a thermal enclosure or an air blower. Most often the temperature of points 4 will be slightly decreasing from rotogravure cylinder 2 until they come into contact with the textile support 3. At least their upper part, opposite their lower part or base, in contact with the carpet transfer must however remain in fusion to allow the adhesion of the points 4 on the textile support 3.
  • the polymer dots 4 therefore have a higher viscosity than when they are deposited by the rotogravure cylinder 2, which makes it possible to avoid crossing the textile support 3 by these points 4 while allowing their adhesion to this support 3.
  • the temperature of the base of points 4, in contact with the transfer belt 3, is generally slightly lower than that of the opposite upper side. This state of point 4 is advantageously exploited.
  • the viscosity of the upper part of the point which comes into contact with the support allows adhesion and the higher viscosity of the base of point 4 limits its penetration into the support.
  • the contact of the polymer with the textile support can be carried out when the polymer is at a temperature of approximately 150 to 160 ° C.
  • the viscosity of the polymer is then approximately 25 to 20 MFI (Multi-Flow Index).
  • Cooling the mat makes it possible for the base of the points, in contact with the latter, to be at a temperature below its upper part.
  • the textile support 3 is not then brought to a high temperature and therefore a fragile support can be used without risk of deterioration.
  • the process of the invention allows the use of numerous polymers commonly used in the field of textile coating.
  • polymers commonly used in the field of textile coating.
  • polyesters polyamides, polyolefins, polypropylenes, plasticized polyvinyl chlorides, thermoplastic polyurethanes, low density polyethylenes, high density polyethylenes ...
  • thermoplastic polyurethanes low density polyethylenes
  • high density polyethylenes high density polyethylenes
  • the temperature of the cylinder must be higher than the melting temperature of the polymer so as to give it the necessary viscosity.
  • the polymer does not have to withstand this temperature for a long time.
  • the following temperatures, depending on the different polymers, are preferable: - Plasticized polyvinyl chloride ...
  • the melting point of the polymer must allow the end use of the product: for example, this temperature must be lower than the temperature of the presses used by the manufacturers when they associate the fusible textile with the drapery. It must also be higher than the usual washing or dry cleaning temperature so that these operations do not affect the bonding.
  • the melting temperature is preferably between 70 and 140 ° C.
  • the softening temperature is essential both for the bondability of the polymer and for the determination of its wetting power. Bonding capacity allows textile bonding fusible on the drapery and its wetting power intervenes in the form taken by the drops of polymer when it rests on the transfer fabric.
  • the polymer undergoes the effects of its environment and is degraded.
  • the degradation temperature must not be exceeded.
  • the viscosity of the polymer at the various temperatures to which it is subjected must be taken into account. - At the cylinder temperature, it must be sufficiently fluid to leave the cells and to be deposited on the transfer support. - During the transfer on the partially non-stick mat, it must be viscous enough not to spread and remain in the form of points. - When placed in contact with the textile support, the polymer must impregnate the surface fibers so as to ensure its attachment while remaining on the textile support surface itself.
  • the polymer When the fusible textile is associated with the drapery, the polymer must be fluid enough to impregnate the fibers of the drapery, but also viscous enough to pass neither the drapery nor the textile support.
  • the preferred polymers have a viscosity of between: . 10 and 150g / 10mn MFI (Multi-Flow Index) at 200 ° C, preferably between 20 and 100, . and 1 and 25g / 10mn MFI (Multi-Flow Index) at 130 ° C, preferably between 1 and 15.
  • the physico-chemical properties are involved in the wettability of the polymer.
  • the polymers used must be able to be deposited on the partially non-stick transfer support without losing the point shape and the dimensions given to them by the cylinder cavities.
  • the apparatus of the invention allows the implementation of the method described above. It includes means 6 for supplying and heating the fusible polymer 1, a gravure cylinder in the hollow 2 rotating around an axis 7, a doctor blade 8 intended to collect the mass of adhesive possibly deposited in excess at the rotogravure cylinder surface 2.
  • This transfer mat 5 has a surface which prevents the polymer which it receives from adhering to its surface even at the relatively high temperature at which this polymer can be brought into contact with the textile support 5. The fact that the carpet is non-stick must therefore allow that when the stitches 4 come into contact with the textile support 3 adheres more strongly to this support than to the transfer carpet.
  • the surface of the transfer mat 5 is covered with a layer of silicone or polytetrafluoroethylene, for example known under the name "Teflon”.
  • the apparatus preferably comprises means for cleaning the transfer mat 5 after the deposition of the points 4 on the textile support 3.
  • the means comprise for example a brush 15 and prevent fibers possibly deposited by the textile support 3 on the carpet of trasnfert 5 are deposited on the rotogravure cylinder 2.
  • the apparatus comprises means 9 for supplying the textile support, a cylinder 10 for bringing the textile support into contact with the dots 4 of fusible polymer and means 11 for receiving the fusible textile-based product.
  • It includes a cooling zone 14 located between the contacting cylinder 10 and the receiving means 11.
  • the non-stick mat 5 is closed on itself which allows it to operate in a closed loop and therefore to ensure continuous operation of the whole apparatus.
  • the non-stick mat is carried by a cylinder 12.
  • the distance between this textile support 3 and the non-stick mat 5 is precisely adjusted. It can be set absolutely or in other cases it is the pressure of application of the cylinder 10 for contacting against the non-stick mat 5 which is set. This or these adjustments make it possible to optimize the penetration of the textile support by the points 4 of heat-bonding polymer as well as the thickness of these points after their transfer to the support 3.
  • the method and the apparatus of the invention therefore allow the implementation of a "HOT MELT” coating process in which the phases of carrying out the distribution of the heat-bonding polymer in points is dissociated from that of the deposit of these points on the textile support.
