Definitions

  • the invention relates to a method for transferring motifs applied to a motif carrier by means of color to another carrier, in particular textiles, which can also be washed at up to 95 ° C., this motif carrier being brought into contact with this other carrier with the motif side and the transmission with a transfer liquid and under pressure.
  • textile printing technology it is known to print a black-and-white or colored image to be printed onto a first image carrier, for example a paper sheet or paper strip, and to image the image from this image carrier in a second operation onto the final substrate, in particular a textile material. to print.
  • transfer printing processes are referred to as transfer printing processes. They are carried out in the wet transfer process or dry transfer process. In the wet transfer process, a prepared paper is printed with dye and resin.
  • the transfer printing takes place on a calender at high temperature under pressure and at the same time damping with a suitable agent.
  • the paper is printed with pigment dye and a thermoplastic synthetic resin, so that the transfer printing can be carried out at elevated temperature on an arm calender without additional damping agents.
  • the customary printing methods are high-pressure or flexographic printing, planographic printing or offset printing, gravure printing or squeegee printing, and screen printing. In high pressure, the elements to be printed are raised, while the printing form is flat or cylindrical.
  • the planographic printing, in which printing and non-printing elements lie in the same plane, is based on the fact that the printing parts are made water-repellent by chemical treatment.
  • the printing form is either flat (lithographic printing) or cylindrical (offset printing).
  • a dampening unit is added to the inking unit, which moistens the stone or offset plate before inking.
  • the elements to be printed are deepened by etching or engraving.
  • the excess ink is removed from the printing form flooded with liquid ink, for example by means of a squeegee, so that ink only remains in the lower-lying printing elements.
  • the paper is pressed against the printing form by a printing cylinder, as a result of which the ink is sucked from the wells onto the paper.
  • the printing form consists of a stencil made of color-permeable material (metal or nylon screen).
  • the pasty printing ink is pressed manually or in the screen printing machine with a squeegee through the mesh of the screen onto the printing material.
  • Neither the wet transfer nor the dry transfer method are suitable for transferring such images produced using the customary printing method.
  • DE-OS 17 71 863 a known method is described, by means of which an original document, e.g. B. Art paper, images produced on a new base, for example a surface made of a textile material, wood, stone or the like. Transferred.
  • an intermediate underlay in the form of a non-moisture-sensitive laminate is used, which consists of the following layers in the order mentioned: a base layer, a releasable middle layer, a clear lacquer layer and a glue layer that attaches due to pressure.
  • the disadvantages of this method lie primarily in the inaccuracy of the image transmission and in the presence of poorly transmitted image parts.
  • the intermediate carrier was an extremely complicated object.
  • the methods described in DE-OS 17 71 863 should avoid these difficulties in that the printing ink layer covering the image is coated with an adhesive layer, that a sheet coated with a glue adhering to pressure or the like is coated with the adhesive side is pressed against the printing ink layer, after which the sheet or the like is removed from the printing ink layer, with glue remaining on the printing ink layer, and a non-moisture-sensitive intermediate underlay prepared in advance is pressed onto the glue material, which is layered one above the other, seen in the direction from the pressure-sensitive glue, consists of a clear lacquer layer, a layer of adhesive that is easily detachable from the clear lacquer layer and a base layer, for example of support material or some other support material, after which the original base is removed from the ink layer and the intermediate base with then be ⁇ f Indian ink layer is applied to the new base, after which the base layer of the intermediate base and the adhesive layer are removed from the clear coat layer.
  • GB-PS 423 727 also describes the transfer of images from a first surface to a second surface.
  • the original motif is treated with a liquid that softens the surface of the intermediate carrier.
  • the intermediate carrier is a paper which is coated with various chemical substances in a complicated and expensive manner.
  • the original base of the motif is then treated with another chemical which causes the base to dissolve, so that the base can detach from the motif now on the intermediate carrier.
  • the motif is then transferred from the intermediate support to the new base.
  • the liquid applied to the original motif is a liquid that dissolves the original base on which the motif is located, or a liquid that softens the surface of the intermediate carrier.
  • motifs brought about by a printing method using conventional printing inks are transferred for the first time from a flexible original base, for example a printed paper, to a new base, in particular one made of leather or wood, the motif being transferred Application of a liquid is detached from the original pad.
  • the new base is wetted with a color-dissolving liquid, preferably with a neutral, non-alkaline, non-ionic surfactant and oil and hydrocarbon-containing solvents.
  • a color-dissolving liquid preferably with a neutral, non-alkaline, non-ionic surfactant and oil and hydrocarbon-containing solvents.
  • the original base with the side on which the motif is located is then placed on the wetted surface of the new base and pressed onto it. Finally, the original document is subtracted from the new document.
  • This method already has considerable advantages, but is essentially related to the transfer of photocopies and does not meet industrial requirements, in particular because of the low washability or low wash resistance and the low color quality or brilliance. It has been found that the main disadvantage for printing textiles is that the transferred motifs fade more and more after each washing process.
  • the present invention is based on the object of eliminating the disadvantages mentioned above and, in particular, of developing a method by means of which images can be transferred inexpensively and quickly, in particular to textile substrates, in such a way that they remain durable on these textile substrates.
  • the solution to this problem is that the motifs are made from a washable color or from a color which is added to the transfer during the transfer and which makes them washable.
  • Oxidative colors are preferred as washable colors. These colors usually do not have a hardener, but harden on their own within a specified period of time. However, after curing, they can no longer be removed by a color-dissolving liquid, so that they can then no longer be transferred from one motif carrier to another carrier.
  • the motif is produced by means of oxidative colors and is transferred to the other carrier immediately or, depending on the delay agent, in a predetermined time. If, for example, four-color printing is carried out, the yellow plate is first printed on the motif carrier. As soon as it has hardened on the surface, the blue plate is printed, after its surface hardening, the red plate is printed and finally the black plate is printed. This sequence is only to be understood as an example and can be changed if this is useful for the process. A motif produced in this way can now be used immediately and placed on a T-shirt, for example.
  • the hardened surface of the paint is broken open, whereby the paint can penetrate into the textile fabric.
  • the transfer liquid also breaks up the hardened surfaces of the following color layers so that they can also penetrate into the textile to be printed. A relatively rapid hardening then takes place there because the oxidative paint is now exposed to the air from all sides and can harden faster.
  • the motif support As the motif support.
  • the oxidative color not only hardens from the surface, but also through the paper from the back.
  • the situation is different if the motif is applied to a film, for example, whereby the oxidative color is not exposed to the air from behind.
  • the shelf life of the motifs produced by the oxidative colors also depends on the motif carrier.
  • Another significant advantage of the method is that it 'takes place the transfer of the motif entirely without the addition of heat, so that' also synthetic material can be treated. Cotton and synthetic material are not subject to any change in shape, so that there is no distortion of the motifs. The image is transferred completely color-fast to the textile substrate and is retained even after a large number of washing processes.
  • the present method prints in use. That is, for example in the screen printing process, the screen is exposed 100 times with the drawn repro and 100 four-color motifs are produced by four printing processes. A further printing process is then necessary for the transfer of each motif. This gives 104 prints. The considerable time savings can be seen from this alone, since 296 prints are less necessary. Correspondingly produced motifs or motif carriers provided with the motifs can easily be stored in stock, which in turn leads to considerable cost savings.
  • the carousel consists of at least four individual stations, in each of which one color is transferred to the substrate to be printed. At least five operators are required in the case of the manually operated carousel; in the case of the automatically operating carousel, the staff is reduced to at least two people.
  • the present process can be used not only with oxidative colors but also with physical colors.
  • these physical colors can be dissolved again by a color-dissolving liquid, and motifs made with them are therefore more storable. This depends above all on the thinner that evaporates during drying and is added to the physical colors.
  • the process can also be carried out with all other colors.
  • the printing technique used to produce the desired motif is irrelevant to the method according to the invention.
  • the motif can be produced both in high printing, in plan printing, in gravure printing and in screen printing. The cheapest solution will have to be selected in individual cases.
  • Each printer can / himself produce the motifs, so that there is no obligation to refer as with the known colors. Both oxidative and physical colors are readily available commercially.
  • the motifs are printed reversed so that they are in the correct position after being transferred to the carrier.
  • This is precisely the essential difference from the method according to DE-PS 27 57 630, according to which a reverse transmission takes place.
  • photocopies that is to say motifs that are true to the page, are usually transferred reversely to a substrate.
  • the motif itself is turned upside down, so that when transferred, a correct image is formed on the T-shirt or the like to be printed. Because of the correct page transfer, characters can also be easily printed on a corresponding substrate.
  • the printing inks transferred with the above-mentioned method adapt to every textile fiber, ie both a natural and a synthetic fiber, the color brilliance of the image being retained in full.
  • the substrate is washable without restriction, and the transferred image has a very high wash resistance.
  • a liquid is to be used as the transfer liquid which consists of an organic solvent, as mentioned for example in DE-PS 27 57 630. These are readily available commercially and are completely non-toxic. Fatty acid esters and here again butyl acetate seem to be most suitable.
  • orange oil in particular having proven particularly advantageous here, above all as far as the light and color fastness of the transferred motif is concerned.
  • soy lecithin concentrate which is also proposed, as a washing-active substance ensures that the interfacial tension of both the new carrier, such as the textile fiber, and the original motif carrier, ie the image surface, is reduced and thus better wetting takes place.
  • citric acid is added to the solvent and this can be done up to an order of magnitude of ten percent by volume.
  • a salt is again added to the solvent, which leads to neutralization.
  • Solvent leads to a significant improvement in image quality and durability.
  • a hardener in the course of the process, be it the color itself or the transfer liquid.
  • the latter is preferred because a motif from a color without a hardener can be more easily detached from the motif carrier by the transfer liquid and the hardener is only added when the colors on a substrate are desired to be stable. This means that the colors can be dissolved on the motif carrier, but after being transferred to the textile substrate by the addition of the hardener in the Tans liquid, they become insoluble.
  • the motif carrier then contains considerable uncertainties regarding the hardening of in particular oxidative colors if it was formed from an absorbent cellulose material, d. H. when using plain paper, for example.
  • the motif carrier contains considerable uncertainties regarding the hardening of in particular oxidative colors if it was formed from an absorbent cellulose material, d. H. when using plain paper, for example.
  • a motif carrier which is formed from at least two layers of different densities.
  • the layer that bears the motif should preferably be made impermeable to the motif color. On the other hand, however, it should in turn be permeable to the transfer liquid.
  • a motif carrier which is marketed under the name Chromolux paper, has proven to be the most suitable. Chromolux paper consists of paper coated on one side, the coated side forming a closed surface which prevents the motif color from penetrating. From the rear, the Chromolux behaves like a permeable paper. If the transfer liquid is applied to this layer, it also penetrates the painted side from behind and thus dissolves the motif color, which is then transferred to the new carrier.
  • the transfer liquid can be applied in various ways, this route depending in particular on the motif carrier and the new carrier.
  • the application methods impregnation, spraying or brushing are to be considered as equivalent.
  • wetting using pens or sprayers can also suffice.
  • These pens are simultaneously pressed onto the motif holder and the new holder.
  • sponge-like application devices are also conceivable, in which case a certain portioning of the transfer liquid to be applied should follow. For example, a corresponding portioning takes place when a solid material with an uneven surface is used as the application medium. Holes are formed from the uneven surface in which the transfer liquid can hold due to its own adhesive forces and are only sucked off when the solid material is placed on the motif carrier or the new carrier.
  • a motif is applied to a motif carrier, for example in four-color printing.
  • the printing process is irrelevant, preferred motif carriers are described above.
  • this motif carrier is brought into contact with the base to be printed or the new carrier, which is wetted with transfer liquid shortly before or during insertion into the press.
  • the motif color is dissolved by the transfer liquid and connects to the new carrier, this connection being accelerated and improved by adding pressure.
  • the motif carrier and the new carrier are separated from each other, whereby the motif sticks to the new carrier.
  • presses are used for the method according to the invention. Presses can be hydraulic, pneumatic, electromagnetic or the like. Even hand printing, such as occurs when transferring images using color-resolving liquid in pens, is sufficient in some cases. Depending on which quantities or series of printed substrates are produced, the press is also adapted to the necessary requirements. This can go as far as fully automatic presses operating in three shifts.
  • the image to be transmitted regardless of how many prints it consists of, is transmitted in its entirety and so there are no passport problems that could only be eliminated to a small extent by additional human control.
  • Motif carriers as well as color-resolving liquid and presses are easy to handle materials or objects. This makes it possible to set up a mobile print shop that can come into the house itself if desired and also print on objects that are immovable or difficult to move. With a suitable press, motifs can also be transferred to walls, tables, chairs or the like at any time. The result should be noted again:
  • the image applied to a washable substrate is washable, regardless of whether it is a natural or synthetic substrate.
  • the same also applies to chemical cleaning, which also does nothing to the image. Ironing is easily possible.
  • Every private person can apply desired images to a desired substrate, but also every printer can produce motifs himself and apply them quickly and without rejects in small and large runs to substrates.
