Definitions

• Decorative flocked structures or objects e.g. fully flocked flock cloth for e.g. Upholstery purposes or decorative flocked T-shirts, sportswear with club emblems, groups of letters, numbers, advertising slogans or trademarks of the manufacturer, are becoming increasingly fashionable.
• the decorative flocked T-shirts, sports clothing items and the like are increasingly replacing T-shirts or sports clothing items on which the decoration is only printed or ironed on.
• afterglow decorations or information can also be applied to textile structures, such as T-shirts or sports clothing.
• the decoration shows no textile character, which, as described, can be recognized by at least temporarily uncomfortable wearing properties.
• flocked structures essentially three known measures, namely direct flocking, transfer flocking and iron-on flocking.
• the relevant procedural measures are known and need not be explained in more detail here.
• the three essential methods have in common that the flock is bound to the substrate via an adhesive region or an adhesive layer.
• a wide variety of flocking adhesives in the form of dispersion adhesives, solvent-based adhesives or solvent-free adhesives based on homo- and copolymeric PVC pastes, single- and multi-component polyurethane systems and the like are used to absorb the short staple fibers that form the flock and anchor them on the substrate. known.
• acrylate dispersions particularly those with a high adhesive content, are preferably used.
• the invention was based on the object, inexpensive afterglow, flocked structures of all kinds, that is, with both flat and decorative, afterglow To produce flocks loaded substrates, whereby a good and lasting afterglow effect of the flock is achieved and no staple fibers weakened by pigment inclusions are to be used in the production of the flock.
• the object of the invention is thus a structure in the form of a substrate which is subjected to afterglow flock: which is characterized in that an afterglow pigment is accommodated in the flocking adhesive area.
• the introduction of the afterglow pigment into the adhesive can, for example, be such that the flocking adhesive is first applied, then flocked, and finally the pigment powder is shot between the flock and the open adhesive.
• the pigment is preferably applied to the substrate together, ie in a mixture with the flocking adhesive, and only then flocked.
• the flocking adhesive area can also be designed in multiple layers.
• a highly pigmented adhesive is first applied, which is then lightly dried, provided with a layer of a transparent flocking adhesive and flocked on the latter.
• the entire afterglow pigment is in the lower of the two layers. It is also conceivable that the afterglow pigment increases in quantity in one or more adhesive layers in the direction from the flock to the substrate.
• Another way of avoiding flocculation problems (eg deterioration in abrasion and wash resistance) when using Flocking adhesives with a high (afterglow) pigment filling consist of lowering the evenly distributed pigments towards the substrate with the help of a high-voltage electrode located under the adhesive, which is activated briefly after the adhesive has been applied and before the flocking process, and thus in the lower, to concentrate the layer of adhesive close to the substrate. This greatly reduces the pigment content in the upper layer of the adhesive, so that the adhesive content of the adhesive is available for flock adhesion.
• the high-voltage supply has a negative or positive charge sign and can be regulated from 0 - 100 KV.
• the voltage value to be selected depends on the relative dielectric constant of the pigment and the insulation value of the substrate.
• Suitable as high-voltage electrodes are those in the form of rods, wires, grids or plates, bright metal or non-conductive plastic, completely or partially covered.
• any conventional afterglow pigment but preferably afterglow ZnS, with a particle size of about 10-20 ⁇ m, preferably below about 15 ⁇ m, is suitable as the afterglow pigment.
• the afterglow pigment should preferably be rounded or spherical for reasons of good flockability of the adhesive area.
• the afterglow pigment is located at a location separate from the flocking point, it can also have a different shape, e.g. be needle or tabular.
• the concept according to the invention can be applied to all known flocking measures, e.g. the direct, transfer or iron-on flocking, realizing only that care must be taken to ensure that the afterglow pigment (in the final state) is accommodated in the adhesive area under the flock. It does not matter whether there is another layer of adhesive between the adhesive area and the substrate.
