Definitions

  • the invention relates to opaque textile flat products, in particular for opaque items of clothing, and to a manufacturing method for opaque textile flat products.
  • Such a coating consists of a foamed acrylic-based polymer coating.
  • a blackout coating is provided with a textile on both the top and the bottom, so that a sandwich structure with a blackout middle layer results.
  • US 2002 0 1 22 949 A1 describes, for example, a structure of a textile product with two textile outer layers and an inner metal film which makes the textile product opaque. Furthermore, such a coating can contain graphite particles, for example, in order to make curtains more opaque. It is also known that the transparency of curtains can be restricted by using thick fiber materials and by using particularly tight interweaving, looping or looping. Presentation of the invention
  • Another object of the invention is to provide a flat textile product which is essentially opaque.
  • a flat textile product is provided which is particularly suitable for sportswear due to its breathability and / or water-repellent effect.
  • a thin and / or light, opaque textile flat product is provided.
  • the invention relates to a textile flat product with an upper side and a lower side.
  • the top side has a hydrophobic fine coating and the bottom side has an opaque impregnation.
  • the opaque impregnation comprises at least one polymer resin, at least one metal salt and at least one pigment, in particular a colored pigment.
  • Impregnation and fine coating in the context of the present invention denote a treatment which at least partially penetrates the textile or soaks the textile. In this case, the thickness of the substrate to be impregnated or the substrate to be finely coated is not significantly increased by the impregnation or the fine coating. In general, such impregnations or fine coatings cannot be seen with the naked eye, but only with the help of a
  • Impregnation and fine coating thus differ from a full coating of the textile, which completely covers the surface of the textile, the thickness of which is thereby widened, but not significantly into the textile penetrates. Impregnation typically introduces solids dissolved or suspended therein into the textile carrier material. While the textile carrier material can be sealed with a full coating, in contrast to this, a textile carrier material is not sealed by a fine coating or impregnation. In a textile flat product according to the present invention, the metal salt and the pigment are typically arranged between the fibers of the textile carrier material. The person skilled in the art understands that the opaque impregnation lies on the inside of an item of clothing, ie is directed towards the wearer's skin when it is worn.
  • the at least one pigment is typically colored and / or light-absorbing.
  • the at least one pigment preferably comprises carbon black or can consist of carbon black.
  • other colored pigments can also be used, for example colored copper salts such as copper (II) phthalocyanine.
  • the grain size of the at least one pigment can be from 10 to 1000 nm, preferably from 100 to 500 nm, particularly preferably from 200 to 300 nm. The person skilled in the art understands that the grain size can be determined by standard sieve analysis, in particular using sieves with a predetermined mesh size.
  • the top and the bottom denote opposite sides of the textile carrier material, which, however, are not to be understood as two-dimensional planes, but can also have a certain thickness in addition to length and width and can thus define areas of the textile carrier material.
  • the surface of the upper side or the underside denotes the outer boundary surface of the textile carrier material or the textile flat product to the environment. It is therefore understood that the hydrophobic fine coating, viewed from the surface of the upper side, partially penetrates into the textile carrier material and the opaque impregnation penetrates into the textile carrier material when viewed from the surface of the lower side. The opaque impregnation and the hydrophobic fine coating thus at least partially penetrate the textile carrier material different sides.
  • opaque impregnation denotes an impregnation that reduces the transparency or the light permeability of the textile carrier material at least significantly compared to a non-impregnated carrier material.

Journ. Opt. Soc Amer. 1943, 33, 385 and Cleland A Grammer of Color: Basis Treatise on the Color System of Albert H. Munsell New York 1969) of at least 7, in particular at least 8, preferably at least 9, particularly preferably 10.
  • the brightness or the white appearance of the textile carrier material is essentially retained. This advantageous effect occurs to a greater extent when the opaque impregnation only partially penetrates the textile carrier material, i.e. does not completely penetrate it.
  • the hydrophobic fine coating of the upper side of the textile carrier material has no darkening effect, so it is preferably essentially transparent, so that the lower side continues to have the color and / or the brightness of the textile carrier material.
  • the hydrophobic fine coating has the additional advantage that the textile flat product offers protection against moisture and is also easy to clean. Normally, in the case of white and / or light-colored textile surface products, darkening and / or greatly increasing transparency is observed when exposed to moisture and moisture.
  • the hydrophobic fine coating means that the textile flat product retains its original white color or its original brightness even when exposed to moisture and moisture and can prevent or at least reduce this darkening effect.
  • Both the at least one Meta II salt and the pigment are preferably present as particles which can be arranged within the textile carrier material and on the surface of the underside.
  • the surface of the upper side of the textile sheet product is preferably free of the opaque impregnation and the surface of the underside of the textile sheet product is typically free of the hydrophobic fine coating.
  • the light permeability of the flat textile product can be determined colorimetrically by determining and comparing the brightness of the flat textile product on a standardized black background and on a standardized white background. The less the brightness values determined in this way differ from one another, the more opaque the textile surface product is.
  • the opaque impregnation can be hydrophilic.
  • the opaque impregnation and the hydrophobic fine coating are essentially completely separate within the textile carrier material, are consequently not mixed with one another and contact each other at most at an interface within the textile carrier material.
  • Embodiments with a hydrophilic, opaque impregnation are particularly advantageous for wearing comfort, since the hydrophilic impregnation significantly improves the absorption of moisture on the underside.
  • Moisture which is given off by the body of a wearer during sporting activity or heat, is thus conducted into the textile surface product, penetrates it and is efficiently given off to the environment with the help of the hydrophobic fine coating.
  • sweat stains due to the combination of the hydrophilic impregnation and hydrophobic fine coating is no longer visible or, compared to untreated clothing, is clearly less visible.
  • the at least one pigment comprises carbon black.
  • the at least one pigment can also consist of carbon black.
  • carbon black By using carbon black, the proportion of metal salt that is necessary to make the textile sheet-like product opaque can be significantly reduced or the light permeability can be greatly improved while the metal salt content remains the same.
