Definitions

  • the invention relates to a nubuck or suede-like or textile-velor-like substrate, with a textile carrier body with a surface that is rough at least on one side, which is at least partially impregnated with a polymeric plastic material that is foamed by the introduction of air.
  • the invention further relates to a method for producing such a substrate.
  • Non-impregnated nonwovens have excellent puncture and tear resistance properties. However, their main disadvantage is that their surface is unstable and changes very much, especially when stretched. Another disadvantage of these nonwovens lies in the fact that they have a considerably changing thickness. If such nonwovens are used as a carrier material for a plastic coating, it is necessary to provide correspondingly thick, heavy and therefore expensive plastic coatings in order to compensate for the fluctuations in thickness and to eliminate the unrest on the surface of the nonwoven. Although it has already been proposed to use foamed PVC or foamed PUR as the coating material, which reduces the weight, such foamed coatings have poor abrasion properties and tend to split.
  • a carrier material formed from a nonwoven made of textile fibers is impregnated with a polymer plastic material which is arranged in the carrier material in different distributions, the substrate thus formed being compressed after the plastic material has solidified.
  • the substrate becomes hard and stiff, so it has no leather-like properties and therefore cannot be used as a substitute for leather.
  • the tear strength and puncture resistance of the substrate is very poor.
  • a process for the production of porous textile fabrics with leather-like grain has also been proposed, according to which a base fabric made of shrinkable fibers is impregnated on one or both sides with a flowable, heat-reactive polymer, which has been made foam-like, for example, by incorporating air, whereupon the impregnated fabric is dried by the application of heat and is allowed to shrink by treatment with water or steam (DE-A-21 64 852).
  • a base fabric made of shrinkable fibers is impregnated on one or both sides with a flowable, heat-reactive polymer, which has been made foam-like, for example, by incorporating air, whereupon the impregnated fabric is dried by the application of heat and is allowed to shrink by treatment with water or steam (DE-A-21 64 852).

  • the substrate according to the invention is suitable, for example, as a leather substitute, but is also particularly suitable as a material for the interior of vehicles, in particular motor vehicles, since it is stretchable and can be deformed well.
  • a particularly high permeability to air and water vapor results when the foamed polymeric plastic material has open cells formed solely by introducing air. This is useful, for example, if the substrate or the like in the manufacture of shoes, protectors or the like, but also for the interior of vehicles, rooms or the like. and is used as a covering material for upholstery.
  • the polymeric plastic material has, in addition to the open cells formed by introducing air, hollow cells formed by hollow microspheres. It is advantageous here if at least some of the hollow microspheres located on the impregnated surface of the carrier body are open, since this improves the velor effect.
  • the textile carrier body is at least partially made of plastic fibers, for example polyester fibers or Polyamide fibers. This is particularly advantageous if the substrate according to the invention is heated and deformed by means of high frequency.
  • a particularly attractive surface is also obtained when the fibers are thinner than 3.5 dtex, preferably thinner than 2 dtex.
  • the carrier body can consist of several interconnected webs.
  • the textile carrier body can be formed from a natural fiber fleece and a synthetic fiber fleece, preferably of approximately the same weight, needled together with the natural fiber fleece.

  • high-strength fibers are sold in the German Federal Republic under the trademarks KEVLAR and NOMEX.
  • KEVLAR and NOMEX are sold in the German Federal Republic under the trademarks KEVLAR and NOMEX.
  • a thin, light fleece with a basis weight of approximately 150 g / m 2 can be used as the carrier body, so that this substrate is particularly suitable, for example, for shoe upper material.
  • a beautiful, even velor effect is obtained when the majority of the cells in the polymer plastic material are smaller than 125 ⁇ .

  • the textile carrier body is provided with a non-stick finish made of a layer at least partially enveloping the fibers forming the carrier body.
  • This layer can consist, for example, of silicone, polytetrafluoroethylene, polyethylene, wax, paraffin, polyolefin or similar materials, or of mixtures thereof, that is to say of substances which are above all water-repellent and therefore prevent the dispersion from adhering to the fibers.
  • the layer can also consist of a substance that is soluble in a liquid, in particular water or alcohol, for example gelatin, starch, soaps, fatty alcohols, polyvinyl alcohol, water glass, or mixtures thereof.
  • This layer initially surrounds the fibers and prevents the plastic material from adhering to them, in particular also at the crossing points, but can be at least partially removed again during or after the plastic material has solidified by the liquid (water, alcohol or the like), so that then the fibers in the plastic foam are, as it were, freely movable, thereby not only improving the softness and flexibility of the substrate produced in this way, but also forming capillary cavities in this substrate, which increase the moisture permeability in the desired manner.
  • the aqueous plastic dispersion itself will absorb this layer.
  • the substrate according to the invention expediently has a density of less than 0.45.
  • the substrate is provided with a print and a preferably transparent finish on at least one surface, as a result of which a desired, for example leather or textile, appearance is achieved.
  • the substrate according to the invention can be used without a coating, for example as an absorbent, breathable shoe lining material or insole material or as velor material for vehicles.
  • a surface is provided with a thin coating, preferably made of polyurethane or PVC, the fibers protruding from the surface are embedded in the coating.

  • the coating can have a thickness of less than 0.35 mm.
  • the coating can be applied to the impregnated and ground surface of the carrier body.
  • the procedure according to the invention is such that the foam-like polymeric Plastic material, which consists of an aqueous plastic dispersion, is introduced into the carrier body consisting of a nonwoven or knitted fabric by the action of excess pressure and / or negative pressure, that the impregnated carrier body is dried by dehydration, and that the impregnated surface of the carrier body is then ground.
  • the action of the blow foam by overpressure takes place, for example, by exposure to compressed air or compressed gas and / or by mechanical pressing of the blow foam into the carrier body.
  • the introduction of the whipped foam by the action of overpressure and / or underpressure ensures that the foam structure is not destroyed during this introduction into the carrier body, but rather is maintained to the desired extent in the region of the carrier body to be impregnated.
  • the subsequent drying by the application of heat preferably one Temperature above 100 ° C, due to the expansion of the air in the whipped foam, a large number of the cell walls in the drying whipped foam burst, which results in the desired air and water vapor permeability to a large extent.
  • whipped foam also has the advantage that the volume of the whipped foam is roughly doubled compared to the volume of the undefeated dispersion without the water: solid ratio changing, so that a smaller amount of water is used to impregnate the desired area of the textile carrier body is necessary, so a smaller amount of water must be removed again when drying. This saves on material and energy.
  • the hollow aqueous plastic dispersion made into foam by introducing air can be admixed with hollow microspheres made of a thermoplastic plastic material, preferably made of polyvinyl chloride, or compact particles containing a blowing agent made of a thermoplastic plastic material, preferably made of polyvinyl chloride, from which compact particles hollow microspheres are formed in situ by the application of heat. If the hollow microspheres are formed from the compact particles during the drying of the impregnated carrier body, the whipped foam is also expanded, which likewise causes the cell walls to burst.

  • compact particles containing a blowing agent made of a thermoplastic plastic material preferably made of polyvinyl chloride
  • the hollow microspheres that form during drying also lead to a spontaneous increase in the viscosity of the still liquid whipped foam and thus not only prevent the drying whipped foam from contracting at the points of intersection of the fibers and a reduction in volume of the whipped foam due to the loss of liquid during drying, but rather the whipped foam experiences through the forming hollow microspheres an increase in volume.
  • the aqueous plastic dispersion is exposed to heat-sensitive measures, for example by means of a substance such as polyvinyl methyl ether, or is adjusted to a pH that deviates from the pH of the textile carrier body or the fibers forming this textile carrier body, that is to say acidic or alkaline is opposed to the textile carrier body. In any case, this causes the plastic dispersion to coagulate, thereby accelerating the solidification thereof and causing additional foam formation.
  • the textile carrier body or the fibers forming this textile carrier body are coated with a coating of water-deviating material, for example silicone, polytetrafluoroethylene, polyethylene, wax, paraffin, polyolefin or similar materials or mixtures, before introducing the aqueous plastic dispersion therein from this, is or will be provided.
  • This water-repellent material repels the aqueous plastic dispersion so that there is no bond between the plastic foam and the textile carrier material.
  • Another particularly advantageous way of preventing such a binding is to coat the textile carrier body or the fibers forming this textile carrier body with a coating of a liquid, e.g. Water or alcohol to provide soluble substance and after solidification of the whipped foam to remove this substance at least partially by the action of the liquid mentioned.
  • a liquid e.g. Water or alcohol

  • the plastic foam is thus introduced into the textile backing material in two steps, which simplifies production.
  • different plastic dispersions can be used and can thus be adapted to the respective requirements.
  • hollow microspheres are formed in situ during the drying of the plastic foam, as already mentioned, during the drying process there is an increase in volume and thus an increase in the thickness of the impregnated textile carrier body.
