Definitions

  • the invention relates to a method for increasing the resistance of prints on absorbent substrates, in particular fabric, fabric, satin, nonwoven, etc.
  • resistance is meant a resistance to external influences, in particular weather resistance, washing resistance, dry and wet cleaning resistance and resistance to mechanical loads, such as Abrasion, or against chemical loads, e.g. against acids, bases, solvents, gases, vapors or fats.
  • the substrate can be given a form, which can contain, for example, the company name or other (standardized) information.
  • This type of imprint is usually applied during the production of the information carrier using the usual printing methods (eg flexographic, offset, letterpress, gravure or letterpress printing).
  • These information carriers which have all been given the same form or are possibly not printed, are usually also printed with individual information.
  • the EDP printer transfers the colored medium to the substrate through its printing unit.
  • an impact printer e.g. needle, matrix, type wheel, ball-head printer
  • a color transfer by a thermal transfer printer from an ink pad by means of a stamp or any other type of color transfer possible.
  • the substrates used are usually a wide variety of fiber materials, e.g. (if necessary wet or lye resistant) fabrics and fabrics made of natural or synthetic fibers or a mixture thereof, satin, as well as more or less unoriented fiber products such as Fleece. Since all of these substrates have voids between the fibers and some of the fibers themselves are porous, the substrates are absorbent. This means that any applied color (regardless of the method of color transfer) can penetrate into the substrate.
  • the printing ink can be removed to a greater or lesser extent by external influences, for example weather, washing, dry or wet cleaning, abrasion, etc.
  • external influences for example weather, washing, dry or wet cleaning, abrasion, etc.
  • attempts have been made to increase the resistance of the subsequent printing by using special color ribbons or by using substrates which have particularly good affinities for the printing ink.
  • FR-A-2 278 832 a method for increasing the adhesive strength of prints on textile materials is known.
  • the materials are coated with a crosslinking system and then printed.
  • the print is a thermal transfer print with sublimable dyes.
  • the object of the invention is to develop a method according to which the substrate is pretreated in order to increase the durability of an imprint to be carried out by means of a printer (both pre-printing and subsequent printing). According to the invention, the method can also be used if only one of the two types of printing is to be carried out.
  • the resistance of a subsequently applied print can be significantly increased by prior painting or full-surface printing of the substrate with a paint or a printing ink.
  • the painting / printing can of course also be carried out optionally only at those points where a form and / or a subsequent print is to be made later.
  • the effect of the increased resistance is based on the one hand on the fact that the fibers of the substrate, in particular in layers near the surface, are better anchored in the overall composite and thus the printed (colored or blackened) fibers cannot be easily removed.
  • the pores in the substrate are so narrowed by the coating that the color penetrates, but can no longer be easily removed.
  • fillers are added to the lacquer, which help the lacquer layer to become microporosity.
  • Suitable fillers are e.g. finely divided silica, diatomaceous earth, chalk, calcium silicate, talc, mica and / or kaolin.
  • the coating is also to produce special optical effects, customary white or color pigments can also be added. Then the structure of the varnish practically corresponds to a printing ink. Fillers with particularly large, platelet-shaped crystals can also be used for special optical iridescence effects. Examples include mica and kaolin.
  • the lacquer must be resistant to the stresses of external influences on the one hand and on the other hand have good adhesive strength even under the external influences that occur on the substrate.
  • the resistance of the lacquer itself is particularly high when it is a cross-linking system.
  • This can be radiation-crosslinking, moisture-crosslinking, thermally or time-curing, one or two or more components.
  • Systems that crosslink at room temperature within a certain period of time are the easiest to use in terms of painting technology.
  • the application can be carried out from solution in solvents, from a dispersion, in particular aqueous dispersion, or without solvents or dispersants, e.g. done from the melt.
  • Two-component paint resins based on epoxy which have excellent adhesive properties and are used as a solvent system, have proven particularly useful.
  • labels 1 sewn on them, e.g. the washing and care instructions are printed.
  • these labels receive an imprint or a form 2 from the label manufacturer, e.g. in the flexographic printing process as requested by the clothing manufacturer.
  • This prints with an EDP printer, e.g. Matrix printer, the size and care instructions 3 for the garment just made on it, to match the form.
  • EDP printer e.g. Matrix printer
  • the label consists of a nonwoven material.
  • the labels are previously coated by the label manufacturer as part of the manufacturing process (printing, punching or perforating) before both printing processes, in this Trap all over.
  • an epoxy resin lacquer based on bisphenol A For example, an epoxy resin lacquer based on bisphenol A.
  • epoxy resin lacquers on a different basis are just as conceivable as any other lacquer or binder.
  • a polyamide amine based on a dimeric fatty acid together with p-amine was selected from the myriad of possibilities as the hardener component.
  • an antiblocking agent can be used, e.g. Silicones, waxes or acid amides. However, it must be used sparingly so that there are no difficulties with subsequent printing (concentration around or below 1%). As a rule, no antiblocking agent is required.
  • the paint can harden during transport or during storage at room temperature (chemical crosslinking reaction).
  • the curing time is about two days. Annealing, i.e. post-heat treatment of the coated labels for thermosetting, is thus eliminated.
  • the fibers 5 are better embedded in the lacquer, the fiber detachment is very difficult. This contributes greatly to the preservation of the printed image. Due to the narrowing of the pores and spaces 6 between the fibers through the coating 7, the printing ink 4 penetrates deeper into the thinner capillaries 6, the surface area for the wash liquor is greatly reduced with the same amount of ink, as a result of which less ink can be detached from the label. In addition, the printing ink can still penetrate into fine pores 8 in the lacquer 7 itself, since this is filled with fillers.
