Definitions

  • This invention relates to image transfer methods employing a layer of clear tacky contact adhesive as an indicia carrier to absorb indicia from a printed, deco ⁇ rated, or illustrated page, document, or other paper sheet for transfer to fabric, the paper sheet being soaked or washed away with water following absorption of the indicia and prior to transfer of the indicia to the fabric.
  • thermoplastic elastomer layer which is intended to be fused to the fabric to anchor the indicia carrier to the fabric and to protect the trans ⁇ ferred indicia against abrasion, laundering, and the like, as for example in the method shown in Stuart U.S. patent 3,985,602.
  • Such fusing of the thermoplastic elas ⁇ tomer anchoring layer requires application of heat while at the same time dimensional stability and integrity of the indicia carrier are required to be maintained.
  • temporary support layers have been provided over the thermoplastic elastomer layer.
  • Such temporary support layers are maintained as part of the web construction through several steps of the transfer process, and are intended to be removed only following initial application of heat and partial fusing of the thermoplastic elastomer anchoring layer to the' fabric. Additional heat is then provided to complete fusing.
  • initial application of heat through the tempo ⁇ rary support web to accomplish partial fusing of the thermoplastic elastomer has not been generally satisfac ⁇ tory because of damage to the temporary support layer and interference of s.uch procedure with proper release of the temporary support layer. Such interference causes par ⁇ tial lifting and distortion of the indicia carrier layer when stripping away of the temporary support layer is attempted.
  • the present invention provides a reliable pro ⁇ cess for absorbing indicia from a paper, page or document and transferring the indicia to T-shirts and other fab ⁇ rics, a process that may be easily completed in a commer ⁇ cial T-shirt shop by use of a heat transfer press common ⁇ ly available in such shops for transfer of decals.
  • the invention improves on prior methods by using a temporary support layer of plastic that is both water- impervious and heat-resistant, and that has a non- silicone high release coating which positively differen ⁇ tiates from the low release of a protective liner and which, together with the temporary support layer, estab ⁇ lishes a potential for uniformity of high release action even following heating of the construction such that there are no localized areas of abnormally high release, maintaining that temporary support layer as part of the indicia including sandwich of layers during soaking or washing away of the paper from which the indicia are absorbed, and, during the application of the indicia carrier to the fabric and the initiation of the fusing of the thermoplastic elastomer layer, applying heat and pressure through the temporary support layer to the thermoplastic elastomer layer and the fabric to thereby initially fuse the thermoplastic elastomer layer along with the carrier layer and indicia to the fabric by application of both heat and pressure simultaneously to both the thermoplastic elastomer layer and the fabric to establish
  • FIGS. 1 through 8 are diagram ⁇ matic illustrations of successive stages in the practice of the image transfer process, showing in schematic cross section the various elements being processed. Dimensions are not necessarily to scale and, in particular, thick ⁇ nesses are greatly exaggerated. DETAILED DESCRIPTION OF THE DRAWINGS
  • FIG. 1 shows indicia 10 such as text or illus ⁇ trative or decorative matter which has been printed or otherwise attached to paper 12, and which is to be trans ⁇ ferred to a fabric backing member.
  • indicia 10 such as text or illus ⁇ trative or decorative matter which has been printed or otherwise attached to paper 12, and which is to be trans ⁇ ferred to a fabric backing member.
  • FIG. 2 illustrates initial steps in the practice of the invention.
  • an indi ⁇ cia carrier layer 14 of tacky contact adhesive is com ⁇ bined between a thermoplastic elastomer layer 16 and a protective release liner 20 which may have a conventional silicone low level release coat 18.
  • a temporary support layer is combined on the side of the .thermoplastic layer- 16 that is remote from the indicia carrier layer 14, and such temporary support layer is maintained in its sup ⁇ porting relationship through at least the washing step.
  • a polymeric tempo ⁇ rary support layer 22 is provided that is both heat- resistant and water-impervious, and that is provided with a non-silicone high level release coat 24.
  • This combin ⁇ ing step may be either before, during or after the pre ⁇ viously described combining step.
  • the temporary support layer 22 of heat-resistant, water-impervious polymer will subsequently (at the stage illustrated in FIG. 4) tempo ⁇ rarily form part of an indicia-including sandwich of layers along with the thermoplastic elastomer layer 16 and indicia carrier layer 14, and.initially also the paper 10.
  • the non-silicone release coating 24 positively establishes a differentiation of its release action rela ⁇ tive to the release action of the protective release
  • the non-silicone release coating 24, together with the temporary support layer, also establishes a potential for uniformity of high release action even following heating of the con ⁇ struction such that there will be no areas of abnormally high release when the temporary support layer is stripped from the remainder of the indicia-including sandwich of layers.
  • the temporary support layer 22 of heat- resistant, water-impervious polymer is preferably a poly ⁇ ester such as ICI's "Melinex,” DuPont ⁇ s "Mylar” or Celanese's “Celenar.” Films of these materials are capable of withstanding temperatures approaching 400° F or more, and are capable of sealing laminates of which they form the outer layer against the ingress of water over extended periods, and easily over periods of several hours or overnight.
  • Representative formulas for the non-silicone release coat 24 are as follows: Formula A
  • Formula A is presently preferred. These coat ⁇ ings may be applied by gravure, wire-wound bar, air knife, or the like, and dried.
  • FIGS. 3-7 are ec- formed by an operator at a T-shirt store using a heated press which is part of the normal equipment of such a store, following commercial distribution of the combined layers seen in FIG. 2 and their storage until the time the process is ready to be completed with reference to specific indicia 12 on a specific paper sheet 10.
  • the protective release liner 20 (together with its silicone low level release coat 18 in the illustrated process) is first stripped, leaving the indicia carrier layer 14 momentarily exposed. This step does not affect the stabilizing support to be afforded by the temporary support layer 22 to the indicia-including sandwich of layers due to the positive T/US85/01535
  • the construction is subject to the stresses and strains of handling, which may include lightly rubbing off any final remnants of the paper 10 to the extent necessary to complete removal. Nevertheless, the structure remains stabilized throughout the washing and removing, even when the construction is allowed to soak in water for longer than required for thorough removal, for example, when the cons ruc ion is left soaking overnight. The potential uniform high release action of the non-silicone high level release coat is unaffected by the washing and removing.
  • the remaining layers of the indicia-including sandwich of layers are next placed on the fabric backing members 30, which may be the front or back of a T-shirt, with the surface of the indicia- retaining carrier layer 14 against the backing member 30. Care is taken to position the sandwich of layers so that the indicia 12 are in the desired register on the backing member.
  • a heated press platen With the sandwich of layers supported on the backing member 30 in a press (not shown), a heated press platen is brought down against the top face of the heat-resistant, water-impervious temporary support layer 22 to initially fuse the thermoplastic layer 16, along with the carrier layer 14 and indicia 12, to the backing member 30 by application of both heat and pressure through the temporary support layer 22 and simultaneously to both the thermoplastic elastomer layer 16 and the backing member 30 to establish a firm and uniform initial bond between the backing member and the indicia-including sandwich of layers. The establishment of this initial bond is suggested by the penetration of backing member 30 indicated in FIG. 7.
  • the heat-resistant temporary support layer 30 continues to stabilize the sandwich of layers, even dur ⁇ ing the direct application of heat and pressure through the layer 30,
  • the temporary support layer 22 'with its non-silicone high level release coat 24 is stripped from the thermoplastic elastomer layer 16, which is now firmly and uniformly bonded to the backing member 30, to thereby realize the uniform high release action which was established by the release coat 24 and maintained throughout the various processing steps.
  • uniform high release such that there are no localized areas of abnormally high release, and with the firm and uniform initial bonding on the other hand, separation of the temporary support layer is effected reliably and without degradation of the indicia-including sandwich of layers or distortion or destruction of any portions of the indicia 12.
  • the same heated platen may be used to apply heat and pressure to the remainder of the indicia- including sandwich of layers and through them the backing / S85/01535
  • a protective cover sheet comprising a Teflon-coated fabric sheet of the kind used by T-shirt shops as a pressing sheet (not shown) and having a matte surface is placed over the thermoplastic elastomer layer 16 during this further application of heat and pressure to both protect layer 16 and impart a matte finish thereto.
  • a T-shirt operator preheats the T-shirt or other garment in the transfer press for three or four seconds to get the wrinkles out at a press set ⁇ ting of say 350°F + 25°F.
  • the image-carrying layers are applied on the garment and the press is closed for about three seconds at the same- press setting.
  • the press is then opened to strip the temporary support layer 22 with its non-silicone high level release coat 24, and a protective cover sheet with a matte surface is "substi ⁇ tuted" therefor. Then the press is closed again at the same setting for say 20 seconds.
  • the press is then closed for about 15 seconds at the same setting.
  • the press is opened and the layer 22 and non-silicone release coat 24 are stripped, the transfer is complete, having in this instance a glossy finish imparted by the stripped layers.
  • the press temperature required to obtain a good bond varies between about 250° F and 375° F, depend ⁇ ing on the duration of application. Limits on applica ⁇ tion time and temperature are: 11
  • the times given are minimum total times to ob ⁇ tain a good bond.
  • the time required for initiation of bonding prior to stripping will be say about a fourth to a seventh of the total time, or say about 3 seconds, at 325 F, for example. Additional time at the given temperature does not have a deleterious effect on the material, so that the process will tolerate unskilled or careless operators who may leave the press closed too long. However,- great overexposure to heat, say in excess of two minutes at 325° F, will cause the weave of the fabric to show through to such an.extent as to make the image somewhat hazy. At 400° F, some of the colors in indicia which constitute illustrations or other images begin to change.
  • Release levels in the practice of the invention may average approximately 12 grams for the silicone low level release coat 18 and 38 grams for the non-silicone high level release coat 24, as measured by test PSTC-4 of the Pressure Sensitive Tape Council. This represents a differential of approximately 26 grams between the low and high releases. Average release differential in prior art processes such as those of the type shown in U.S. patent 3,985,602 have tested out to essentially the same value, or even slightly higher (30 grams). Nevertheless, despite the essential equivalence of the average release di ferentials between high and low level release coats as 12
  • thermoplastic elastomer layer is ure- thane.
  • This layer should be formulated to yield a film with at least 3007 ⁇ elongation at break, since substantial stretch is required when bonding to knitted fabrics.
  • Many other materials should perform satisfactorily If formulated to meet this criteria, such as polypropylene, plasticized polyvinyl chloride, vinyl nitrile rubber, rubber hydrochloride, kratons (rubber block copolymers), acrylics, polyvinyl acetate, vinyl chloride-vinyl acetate copolymers, chlorinated rubbers, acrylonitrile-methyl acrylate copolymers, and ethylene-vinyl acetate copolymers,

Abstract

Procédé de transfert de symboles (12) d'un papier (10) à un support en tissu (30) tel qu'un T-shirt, du type où une couche d'adhésif de contact (14) déposée sur le symbole est collée sur le support (30) à l'aide d'une couche élastomère thermoplastique (16). La combinaison de bandes utilisée dans le procédé de transfert est supportée à travers les différentes étapes comprenant le lavage à l'eau et au moins le commencement de la fusion, par une couche de support temporaire en un polymère imperméable et résistant à la chaleur (22) possédant un revêtement sans silicones assurant une excellente séparation (24), et la chaleur et la pression sont appliquées à travers cette couche de manière à souder fortement par fusion les symboles thermoplastiques (12) sur le support (30) avant la séparation de la couche de support temporaire (22). Le collage fort par fusion et l'action de séparation que permet le revêtement sans silicones (24) empêchent toute déformation ou destruction d'une partie quelconque des symboles (12) pendant l'étape de séparation.
