Definitions
- the invention relates to a thermo-release composite consisting of a surface-stable support and a flat plastic layer, with the aid of which it is possible to transfer image motifs to other substrates, preferably to textiles and to finished articles of clothing, such as the chest area of t-shirts. and a method for producing such a thermal release composite.
- DE-OS 1 771 863 describes a method in which on a base, e.g. on art paper, images produced on a new base, for example on a textile material, are transferred.
- a base e.g. on art paper
- images produced on a new base for example on a textile material
- an intermediate underlay in the form of a laminate is used, which consists of the following layers: a carrier layer, a detachable middle layer, a clear lacquer layer and a glue layer.
- the main disadvantage of this method is the inaccuracy of the image transmission. The washing and cleaning resistance is also poor.
- the difficulties of inaccurate image transmission are to be avoided by covering the ink layer covering the image with an adhesive layer, then pressing a sheet coated with glue with the adhesive side against the ink layer, after which the sheet is left behind Glue on the ink layer is peeled off and an intermediate base consisting of a clear lacquer layer, an adhesive layer that is easily detachable from the clear lacquer layer and a base layer is pressed onto the glue, then the original base is removed from the ink layer and the intermediate base with the ink layer thereon applied to the new base and finally the base layer is removed from the clear coat.
- the process is cumbersome and uneconomical.
- GB-PS 423 727 has also described the transfer of images from a first surface to a second.
- the starting motif with a Treated liquid that softens the surface of an intermediate carrier. After the transfer to this intermediate carrier, the original motif can then be transferred to the actual document. This process is also cumbersome. It is also disadvantageous that solvent is necessary.
- DE-PS 27 57 630 describes a method according to which the motifs generated in a printing process using soft printing inks are transferred from a flexible original base, for example a printed paper, to a new base, the motif being applied by applying a liquid is detached from the original document. The new pad is wetted with the color-dissolving liquid and pressed against the original pad. Finally, the original document is separated from the new one. Disadvantages are the use of solvents, the limitation of the process to photocopies, the low resistance to washing and cleaning, and the poor color quality or brilliance. The motifs fade when printing on textiles. Improved wash resistance on textiles is obtained by the process of DE-OS 3 732 489.
- the motifs are produced with wash-resistant paint or paint with a wash-resistant additive.
- this process cannot do without solvents, with which the surface hardened by the abovementioned additive is broken up, so that the color can penetrate into the textile.
- the paint is then oxidatively cured by atmospheric oxygen.
- plastic films are used for the transfer of image motifs from a transfer carrier to a preferably textile substrate in an environmentally friendly manner Laminate paper.
- the sheet-like plastic film produced, for example, by melt extrusion and the sheet-like transfer carrier are usually pulled off two separate supply rolls and laminated together.
- the commercially available laminate composites have the disadvantage that, due to the high pressures that are required during lamination, the film is anchored too strongly on the paper, which has the consequence that, after the image has been transferred, a split within the plastic film when the backing paper is peeled off occurs and thus only part of the film mass is transferred and also the backing paper can only be removed when hot.
- the film splitting results in poor contour sharpness and poor color quality or brilliance.
- expensive plastic material is discarded.
- the need to peel the backing paper while it is hot is a hindrance. If you peel off after cooling, the backing paper splits. Part of the backing paper remains inseparably attached to the substrate, and the hot stripping technique cannot be used for large motifs.
- the carrier after the transfer of the image motif, the carrier should be removable even in the cooled state without risk of splitting the carrier or the plastic layer.
- the transferred image motifs should have a high color brilliance, good sharpness of contours and good resistance to washing and cleaning, so that the image does not fade or hardly occurs after washing.
- thermo-release composite consisting of a surface-stable carrier and a flat plastic layer applied thereon, with the aid of which it is possible to transfer image motifs to substrates, in particular textiles, which is characterized in that the carrier is coated with hot-melt adhesive powder, which is present in an even distribution and is sintered on and compacted in a film-like manner for taking the picture motif thereon.
- the film-like hot melt adhesive layer preferably has only a weak adhesion to the carrier.
- the adhesive force of the hot-melt adhesive layer is set in such a way that after transfer of the image motif under the influence of pressure and temperature to other flat substrates and after cooling, it detaches completely from the carrier and is peeled off with a tensile force of 10 to 250 cN / 5 cm can be.
- thermo-release composite from a surface-stable carrier pretreated with anti-adhesive agent and a plastic layer applied thereon for receiving image motifs and their transfer to flat substrates, such as clothing, textiles, foams, foils, natural and artificial leather, metal, glass, porcelain, wood, artificial surfaces created, which is characterized in that Hot melt adhesive powder is applied to a moist base coat of the carrier or powder-containing paste directly on the carrier, is evenly distributed and dried, and is sintered and compacted like a film.
- the non-pasted hot melt adhesive powder can be sprinkled onto a moist base coat applied to the carrier, uniformly distributed, dried, sintered and compressed.
- the generated thermo-release composite consists of the carrier and the compressed hot-melt adhesive layer on top of it, which can be easily and completely transferred to other substrates alone or with image motifs.
- antiadhesive papers which are supposed to have a weight of 40 to 120 g / m 2, preferably 60-100 g / m 2, can advantageously be used as area-stable supports. These transfer papers are pretreated on one or both sides with antiadhesive agents which have a good release action, which is preferably achieved by applying crosslinkable silicones or simple or complex fatty acid salts.
- the backing papers used must also have sufficient wet strength so that there is no tendency to curl and ripple on contact with the preferably used aqueous dispersions or suspensions which make up the base coat mixture or the coated powder-containing paste.
- the selection of the backing paper also depends on the desired weak adhesive strength of the applied hot melt adhesive layer. It is particularly favorable if the weak adhesive strength after the complete transfer process in the cooled state is in the range from 10 to 250 cN / 5 cm, preferably 10 to 150 cN / 5 cm.
- the plastic layer is advantageously formed on the carrier paper by sprinkling fine-grained hot-melt adhesive powders onto a moist base coat applied to the carrier, to which the powder adheres and which produces the desired weak adhesion.
- a paste containing hot-melt adhesive powder without using a base coat.
- the base layer for example, an aqueous-pasty dispersion of addition-crosslinkable polysiloxanes can be used, which can have a solids content of 3 to 30%, preferably 4 to 20% and also has a relatively strong anti-adhesive effect in the dried state.
- the use of such a base layer is particularly expedient or necessary when the anti-adhesive effect of the pretreated carrier is not sufficient to completely detach the hot-melt adhesive layer in the cold, for example sometimes when the pretreatment of the carrier has been carried out with simple or complex fatty acid salts.
- the base layer can or should also consist of thickened pastes which, when dried, have no anti-adhesive effect. If, for example, the carrier is provided with a largely closed silicone coating, non-repellent, thickened pastes can be applied as a base coat, which only contain water and water-soluble thickener. It can also contain plasticizers be included. They can also contain antiblocking agents, such as paraffin dispersions.
- the task of the moist base coat is, on the one hand, to adhere the hot-melt adhesive product sprinkled on, on the other hand, in coordination with the pretreatment of the backing paper, to achieve good detachability from the backing paper of the surface-compacted hot-melt adhesive layer formed in the subsequent process steps after its transfer process to another substrate.
- the desired weak adhesive strength of the hot-melt adhesive layer on the backing paper should reach such an extent that the work processes when rolling and smoothing, winding, cutting, transporting and providing image motifs are survived without detachment until the transfer process.
- the viscosity of the base coat used is to be adjusted by adding thickener in such a way that optimum spreadability is obtained with the desired application amount.
- the surface spread of the primer should be between 3 and 8 g / m2 when wet.
- other substances can also be used, for example aqueous thickenings of finely dispersed simple or complex salts of fatty acids, thickenings of fluorocarbon resins, of fatty acid condensation products, etc.
- a powder-grain fraction is expediently used which has a particle size of 0 to 160 ⁇ , preferably 0 to 80 ⁇ , and particularly preferably 0 to 50 ⁇ having.
- the use of this fine grain area ensures that a closed hot melt adhesive layer can be formed, the coating weight of which is from about 9 to 40 g / m2, preferably from 9 to 30 g / m2 or also from 14 to 30 g / m2, particularly preferably from 9 to 15 g / m2 is enough.
- the finer the grain fraction used in the specified range the lower the coating weight when the layer is just closed, the softer the grip and the more homogeneous the printed image appears on the textile substrate when an elastic substrate stretches, without changing any other quality characteristics .
- the hot-melt adhesive powder is coarser, the coating weight exceeds the specified limit values when the layer is formed, which has the consequence that the handle on the textile substrate becomes too hard and the layer visibly breaks open under tensile stresses of an elastic textile substrate.
- Materials based on copolyamides, copolyesters, polyethylene vinyl acetates and polyurethanes or mixtures thereof can be considered as hot melt adhesives.
- Copolyester powders have proven to be particularly suitable for textile applications which have a high resistance to washing and a satisfactory resistance to dry cleaning. In order to achieve a uniform formation of the hot melt adhesive layer and a good covering of the textile fibers during the transfer process, powders with a high melt flow under the influence of temperature are expediently used.
- These are preferably powders which have a melting range between 95 and 140 ° C, preferably between 100 and 130 ° C, and a melt index according to DIN 53 735 at 160 ° C and a stamp pressure of 21.6 N, from 35 to 150 g / 10 have min.
- the powders can contain suitable plasticizers in order to achieve a softer feel and an improved coating of the fibers of textile substrates.
- the plasticizers can already be contained in the delivery state of the powder. They can also be added later. In the case of the latter, it is particularly important to note that the plasticizers added are incorporated in such a way that the plasticizer penetrates the powder grains largely homogeneously. This is achieved through an intensive mixing process and a subsequent tempering.
- the plasticizers should be selected and dosed so that the resistance to washing and dry cleaning is not impaired in textile applications.
- Plasticizers based on toluenesulfonamides such as o, p-toluenesulfonamides and their N-substituents, have proven particularly suitable for this.
- dicyclohexyl phthalate which is finely ground, is also used as a powder.
- thermo-release composite on textile substrates
- wetting agents can be added to the hot-melt adhesive powders, which further support the penetration of the hot-melt adhesive layer into the substrate during ironing. This also reduces the phenomenon that the hot-melt adhesive layer transferred to the substrate is applied as a closed-surface structure. Rather, the hot-melt adhesive layer envelops the individual fibers of the substrates and penetrates into the substrate surface in such a way that the closed-surface, break-prone character of the hot-melt adhesive layer is lost, which gives the impression of a homogeneous image even when stretched elastic textile substrate is preserved.
- the hot-melt adhesive layer can be given a matt appearance. In this way, an undesirable gloss can be avoided, especially when used on textiles.
- matting agents for example, finely dispersed titanium dioxide, silicon dioxide or aluminum oxide can be used, which have been produced by flame decomposition of the corresponding chlorides.
- the matting agent in an amount of approx. 1 - 3%, the luminosity of the transferred color motif is not or hardly impaired.
- the hot-melt adhesive powder it is also possible to add larger amounts of approximately 10-20% of covering pigments, such as titanium dioxide pigment, to the hot-melt adhesive powder and then to sprinkle the most homogeneous possible mixture of pigment and hot-melt adhesive powder onto the surface-applied base coat.
- covering pigments such as titanium dioxide pigment
- the manufacturing methodology is the same as for the spreading of unpigmented hot-melt adhesive powder, but the later application is different. While the pigment-free hot melt adhesive layer can be placed directly on the intended surface substrate after application of the image motif, when using the pigmented hot melt adhesive layer, this layer must first be transferred to an intermediate carrier be made from which it is then applied to the intended surface substrate.
- pigments can also be introduced into the hot melt adhesive layer.
- a special feature is the introduction of pearlescent pigments and metal powders, which are also to be mixed as homogeneously as possible with the hot-melt adhesive powder before sprinkling.
- the hot-melt adhesive layer applied and compacted by rolling with a thin dispersion top coat, which should also be meltable and at least water-resistant.
- the dispersion top coat can consist, for example, of non-crosslinking polyurethanes, poly (meth) acrylic acid esters or polyvinyl acetates.
- the spread further compresses to the closed film, and in addition, such a spread has proven to be advantageous in some cases when it is passed through copiers, since fewer disturbances occur.
- the spread with thickening agents can contain plasticizers and pigments.
- Plasticizers are indicated to reduce the melt temperature and melt viscosity of the spread, and the addition of pigment may be useful to increase the opacity of the hot melt adhesive layer.
- thermo-release composites which essentially consists of scraping a viscous-pasty, moist base layer onto a wet-strength, surface-stable carrier paper treated with anti-adhesive agent, onto which a fine-grained, optionally matting agent or pigments is applied containing hot melt adhesive powder is sprinkled, and that the excess of powder not adhering to this base layer is removed again.
