Definitions

  • the invention relates to a textile patch for the repair of textiles, comprising a coating for bonding to a textile.
  • the invention relates to a method for producing a textile patch and the use of a textile patch for the repair of textiles, in particular of garments.
  • Non-reactive thermoplastic hot melt adhesives based on polyurethane, polyester or polyamide are used.
  • a fabric patch precoated with a non-reactive hotmelt adhesive it is applied to the textile to be repaired and melted under the action of heat and light pressure, for example by means of an iron.
  • heat and light pressure for example by means of an iron.
  • a high temperature is necessary, so that the hot melt melts. Due to the applied pressure, this can penetrate into the textile fabric.
  • Non-reactive hotmelt adhesives build their adhesive bond during the cooling process by the transition from liquid to solid state. When re-heating, however, the adhesive bond can be released again.
  • thermoplastic character A disadvantage of the use of these non-reactive adhesive systems is the thermoplastic character.
  • relatively high temperatures are required for melting so that the textile composite, ie the bond, achieves adequate wash resistance. If one uses hot melt adhesives with low melting temperature, then the heat and washing resistance of the bond is too low.
  • hotmelt adhesives with a high melting temperature can often not be processed because the Textiles to be repaired, for example synthetic fibers, are temperature-sensitive and can be destroyed by the necessary high melting temperature.
  • Reactive hot melt adhesives combine the advantages of fast setting non-reactive hot melt adhesives with those of chemically crosslinking adhesives, for example, two-part adhesives. They cure quickly and produce an irreversible adhesive bond through the chemical cross-linking via the adhesive surfaces, which can not be solved by renewed heating.
  • a disadvantage of the use of reactive hot melt adhesives is that after applying the hot melt adhesive to the material to be bonded, the bonding must be done relatively quickly, otherwise the hot melt adhesive reacts with the ambient humidity and thus becomes unusable. The maximum time between application and bonding is in practice only a few hours. In addition, the processing of reactive hot melt adhesives requires expensive special equipment with which the hotmelt adhesive can be heated.
  • the inventor has recognized that it is possible to coat textile patches for the repair of textiles, in particular of clothing, with reactive hot melt adhesives. This can be a permanent and irreversible bonding of textiles can be achieved, which is temperature and wash resistant.
  • Reactive hotmelt adhesives are particularly well suited for the bonding and repair of textiles, since their adhesive bond is not only caused by curing, but above all by the chemical crosslinking of the textiles to be bonded. Nevertheless, the bond has a soft, or elastic, character, which is positive for the repair and the subsequent use of garments.
  • reactive hot melt adhesives have a very broad adhesion spectrum.
  • textiles based on natural fibers, such as cotton or wool can be bonded just as well as synthetic fibers, for example on the basis of polyamides or polyesters.
  • the advantage of the wide range of adhesion allows a nearly universal application of the textile patch for the repair of garments.
  • the hot-melt adhesive can be applied as a film or punctiform or interrupted both on one side and on the other side of the patch.
  • the reactive hot melt adhesive physically binds and is block-free, that is, when such a coated textile is rolled up immediately after application of the hotmelt adhesive and cooling to room temperature, stick the individual layers of the role - even without the use of a Release paper - not with each other. This is advantageous for example for the storage of textile patches.
  • Such textile patches can either be punched out or cut out before the application of the hotmelt adhesive or afterwards. However, it is useful to protect the textile patches in a timely manner after punching or cutting and applying the hot melt adhesive in a moisture-impermeable enclosure.
  • Moisture-proof refers here to the fact that the envelope should be tight against both liquid water and water vapor. As a result, the adhesive can not react with the ambient humidity and can be stored for a limited time - usually one to three months.
  • the wrapper can then be opened by the end user when needed and removed from the patch.
  • the processing of such a textile patch is analogous to the processing of previously known textile patches with thermoplastic coating.
  • the self-adhesive textile patches are thus placed with the coated side on the garment to be repaired and heated with an iron or similar device and thus glued. After final cure with ambient humidity, the textiles are permanently bonded together and the textile or garment can be used like untreated pieces.
  • the inventor proposes to improve a textile patch for repairing textiles, comprising a coating on at least one side of the textile patch for bonding to a textile, in such a way that the at least one-sided coating is a reactive hot melt adhesive.
  • a tear in a garment is to be repaired with a textile patch according to the invention, it makes sense to carry out the coating with the hot melt adhesive only on one side of the textile patch.
  • the coating can also be used on both sides Textile patches are applied without departing from the scope of the invention.
  • the coating can in this case be designed in a very diverse manner, for example over the entire surface or interrupted in the form of dots, serpentine lines, checkerboard patterns, a grid or similar structures.
  • especially rollers are well suited.
  • a punctiform coating for example, a gravure roll is suitable.
  • a punctiform coating is particularly useful in terms of a possible material savings. It consumes less hot melt adhesive than in a full-surface coating, also results in the interrupted, in particular punctiform, coating in addition, a "softer grip" in the bonding, so that it is less noticeable.
  • the patch can be precoated as sheet material, for example, and then punched out or cut out.
  • the patch is also possible to coat prefabricated textile patches.
  • Advantageous for both variants is the application by means of rollers.
  • the textile patch coated according to the invention is stored until it is used in an envelope which is permeable neither to liquid water nor to water vapor.
  • a metal foil in particular an aluminum foil, preferably a coated aluminum foil, which is coated, for example, with polyurethane, is suitable.
  • Metal, in particular aluminum is particularly well suited, since it is impermeable to water and, on the other hand, can simply be welded in the production process for closing.
  • the wrapper may also be a transparent film.
  • a transparent film is less preferred insofar as it can protect the moisture-reactive hot melt adhesive less well from environmental influences, in particular from light, which could make the hot-melt adhesive brittle, or from atmospheric moisture, which could lead to storage stability problems.
  • the envelope has a tearing open for easy opening, to allow easy removal of the envelope and thus to ensure easy handling.
  • the tearing device can be carried out, for example, in the form of an integrated tear strip or a notch on the outer packaging, as they are also used in part in packaging of food.
  • the reactive hot melt adhesive preferably comprises at least one isocyanate-terminated polyurethane prepolymer prepared by reacting suitable polyols with an excess of diisocyanates.
  • Suitable polyols are in particular polyester polyols in question. Particular preference is given to polyester polyols which are solid at room temperature.
  • the reactive hot melt adhesive preferably has a melting point between 80 and 100 ° C.
  • the adhesive after curing has an elastic behavior, in particular an elongation at break measured according to DIN EN 53504 at room temperature (pulling speed of 200 mm / min) of more than 50%, in particular more than 100%, preferably between 200% and 800% ,
  • the invention relates to a method for producing a textile patch according to the invention for the repair of textiles, wherein before or after punching or cutting out the textile patch, a heated liquid reactive hot melt adhesive is applied to at least one side of the textile patch.
  • the invention also relates to the use of a reactive hot melt adhesive applied to a textile patch for repairing textiles, in particular garments.
  • the textile patches 1 each have a different shape. Due to the different shape different motifs can be used, which is preferred, for example, in children as end consumers. In addition, the size of the textile patch 1 can be adjusted to the size of the damage of the garment to be repaired.
  • FIG. 3 shows a schematic flow diagram of the inventive method for using a coated with reactive hot melt adhesive textile patch 1.
  • the textile patches 1 in a watertight outer packaging 4 for example from a coated aluminum foil, from production to use.
  • this outer package 4 should be removed first.
  • the outer package 4 may, for example, have tear tape 5 at which it can be torn open.
  • the textile patch 1 with the coated side is placed on the damage 8 of the garment 6 to be repaired - step 101.
  • the hot melt adhesive must be heated, at least until the melting temperature is reached. This can be done, for example, with a commercial iron 7 in step 102. After the adhesive has cooled, there is a washable and cleanable bond between the textile patch 1 and the garment 6, which is soft and flexible due to the chemical bonding of the reactive hot melt adhesive to the garment 6.
