Definitions

  • the present invention relates to the production of a laminate, in particular to a process for the production of a laminate in the form of a holographic image, typically displayed on an article of clothing.
  • the present invention relates to an improvement in and/or modification of the earlier process in which the outer layer of plastics material compatible with said size is a plastics material which has been provided e.g. by printing, as a pattern which gives a desired image on a surface of a flexible substrate, typically a textile material, and more typically one already made up into an article of clothing.
  • the present invention provides a process for the production of a flexible laminate, which process comprises applying to a surface of a flexible substrate a curable composition in fluid form and comprising a plastics material as a pattern which can provide a desired image or imaging effect, positioning a metal foil bearing a holographic image and having a layer of
  • the composition comprising a plastics material may be applied as a pattern by any suitable means.
  • the composition is applied by silk screen printing and the screen mesh is chosen to match the fineness of the image required.
  • compositions in fluid form comprising a plastics material.
  • plastics material Such compositions are known and generally are:
  • the process of the invention uses a composition which comprises a plastics material suspended in a plasticiser. More preferably, in such compositions the plastics material is PVC and the plasticiser is a plastisol ink.
  • a plastics material is PVC and the plasticiser is a plastisol ink.
  • a plastisol ink is sold as Metatran.
  • the metal foil bearing a holographic image may be any flexible metal foil, but preferably, is an aluminium foil.
  • Such foils are commercially available as hot stamping foils bearing a holographic pattern which are produced to provide a foil to be applied to a rigid substrate, typically a rigid plastics material.
  • the rigid substrate provides a support for the foil so that the holographic effect may be stabilized.
  • the size of a commercial foil is a PVC (polyvinyl chloride) , which is preferred for the foils used in the invention, but other plastics size layers may be employed in the present invention provided they can be adhered to a compatible plastics material in a composition as described above.
  • the foil used in the process of the invention preferably includes a release layer on that surface of the metal foil which does not carry the layer of plastics size. That release layer can serve to provide additional protection for the holographic pattern and is removed after treatment in the process of the invention and before the holographic effect is required.
  • a typical release layer may comprise a polymeric material, for example, a polyester.
  • the flexible substrate may be any such substrate provided only that it is flexible.
  • the substrate is a woven or non-woven web, typically a fabric, and more preferably one which is both flexible and stretchable.
  • the fabric is a natural fabric.
  • the fabric may be a silk, cotton, a cotton/synthetic mix, Lycra, acetate, satin, organza, chiffon, linen, icrofibre, viscose or a simulated suede or any other similar fabric.
  • the flexible substrate is one which has already been made up into a garment of clothing.
  • the substrate is a fabric forming part of a finished garment.
  • the foil and substrate are fed to a laminating station at which heat and pressure can be brought to bear on their combination.
  • the feeding to the laminating station may be on a continuous or batch basis depending on the requirements of the process being effected.
  • the foil or substrate may be supplied continuously or intermittently from rollers on which they may be stored.
  • the laminating station may comprise any form of apparatus or device which can supply heat and pressure under the general requirements stated herein. Furthermore, the construction and arrangement of the station may be varied to suit continuous or batch operation. Thus, in one preferred aspect of the invention the laminating station may comprise at least two rollers between which the foil and substrate may be fed to be pressed together and heated. Alternatively, in another preferred aspect the foil and substrate may be brought together in a heated press which typically may comprise upper and lower heated plates which can be brought together under pressure.
  • the process of the invention is effected under conditions of temperature and time which at least essentially avoid bubble formation.
  • the temperature is believed to be the determining factor and preferably the temperature used to effect adhesion or bonding is one in the range of from about 100°C to about 110°C and typically no higher than about 112°C.
  • a temperature in the given range should be used, and preferably about 100°C.
  • pressure it is preferred to use as high a pressure as is possible within the limits of the press or other apparatus employed, and subject to the requirements of the image or imaging effect to be produced. Typically,

  • the heat and pressure are applied for a sufficient time to enable laminate formation to take place,
  • a variety of dwell times may be employed, although a dwell time of about 20 to about 60 seconds is preferred, more preferably about 22 seconds, especially under the conditions mentioned above.
  • Fabric treated by the process of the invention is a fully flexible laminate which generally has the same or a similar high degree of flexure as the flexible substrate from which it is made.
  • the laminate should always be capable of a high degree of flexure and a treated fabric, for example, should be capable of behaving as a fabric essentially the same as the original fabric.
  • a 100% cotton tee-shirt was printed on its front face with a fine image involving half tones using a silk screen mesh 49T and a fluid composition comprising PVC suspended in a plastisol ink supplied as Metatran adhesive by Sericol of London, United Kingdom.
  • the tee- shirt was then while the adhesive was still in a fluid (or uncured) state laid adhesive side uppermost on a heat transfer press as supplied by Imagine Transfers of Braintree, United Kingdom.
  • a sheet of holographic foil EP49 with PVC 68 sizing
  • the laminate of tee-shirt front and foil was then subjected to a temperature of about 100°C for about 22 seconds in the press, after which the combination was allowed to cool. Finally, the foil was carefully peeled away to remove excess (unstuck) foil to leave a tee- shirt finely decorated with a holographic pattern in the image of the pattern of adhesive laid down with the silk screen.
  • the tee-shirt with the holographic image was machine washable at 40°C and could be tumble dried without destruction of the image or the holographic effect.
  • Example 1 was repeated except that an image was applied to the rear of a waistcoat made of a fleece fabric. Similar results were obtained and again the waistcoat was machine washable and able to be tumble dried without destruction of the image or the holographic effect.
  • Example 1 was repeated, this time with a tee-shirt made of 50% cotton and 50% polyester with essentially the same results.

Abstract

L'invention se rapporte à un procédé de production d'un stratifié souple. Le procédé consiste à appliquer sur la surface d'un substrat souple une composition, fluide, durcissable se composant de matières plastiques représentant un motif permettant d'obtenir une image souhaitée ou un effet d'image. Une feuille de métal supportant une image holographique et comportant une couche d'encollage plastique est positionnée de sorte que la couche d'encollage soit superposée au motif tandis que la composition reste fluide. On applique ensuite à ladite composition de la chaleur et de la pression à un niveau et pour une durée tels que l'on puisse faire adhérer la feuille au substrat par l'intermédiaire de matières plastiques tout en maintenant l'effet holographique. Par la suite, on enlève l'excédent de feuille qui n'avait pas adhéré au substrat afin d'exposer l'image souhaitée ou l'effet d'image. On obtient un stratifié souple, lavable en machine, comportant une image holographique souple.
