Definitions

  • the invention relates to leather, in particular lining leather, which is provided on one side with a coating.
  • Aloe vera has long been known as a versatile medicinal plant and is used for pharmaceutical and cosmetic purposes. A total of about 300 different ingredients of aloe vera are currently identified, including minerals, vitamins, amino acids and phytochemicals. In particular, the aloe vera gel, which is stored in the leaves, has manifold healing effects, especially on the skin.
  • DE 10358534 A describes the use of nonionic surfactants to reduce the adhesion of microorganisms to surfaces such as e.g. Skin or leather, as well as compositions containing these substances.
  • a skin treatment composition further comprises plant extracts, such as aloe vera.
  • WO 03/022203 A discloses mixtures for the treatment of fungal diseases which optionally also contain aloe vera. These mixtures can be applied directly to the skin or e.g. on the leather of shoes, which is in direct contact with the skin, are applied.
  • Additive compositions on flat materials e.g. Leather, described.
  • such a composition may also contain aloe vera extract.
  • GB 2406919 A teaches the impregnation of spectacle bands, e.g. made of leather, with fragrances that serve to repel insects or enhance mood.
  • fragrances for example, aloe vera, eucalyptus or tea tree oil are used.
  • tanned leather is subjected to retreading with aloe vera.
  • the leather is treated with aloe vera powder consisting of aloe vera particles in a gel carrier, eg. On the basis of carrageenan, whereby the Aloe vera particles the penetrate internal fiber matrix of the leather and are temporarily trapped in the fiber matrix.
  • the thus treated leather is particularly suitable for leather articles, such as gloves or shoes, which come into contact with the skin. In such contact, the aloe vera particles trapped in the tanned leather are gradually released and moistened to treat the skin of the wearer.
  • the back side of the leather (the "suede leather side") can be treated by spraying or spreading the aloe vera gel.
  • the object of the invention is to avoid these disadvantages and difficulties and has set itself the task of providing leather, in particular lining leather, in which the unique active substance complex of aloe vera is integrated and from which it can be continuously released over a long period of time to the skin.
  • the aloe vera donating leather should be easy to produce and maintain its "nourishing" properties even when in contact with water.
  • this object is achieved by leather, in particular lining leather, which is provided on one side with a coating, the coating being formed from a hard-layer matrix in which aloe vera particles are embedded.
  • Hard-layer matrix is understood to mean a solid layer of a water-insoluble material in which other constituents, such as aloe vera particles, are embedded.
  • the hard-layer matrix according to the invention can advantageously be a topcoat coating conventionally used for leather, which, depending on the application, is a solvent-dilutable one or aqueous topcoat, for example based on nitrocellulose, cellulose acetate butyrate, acrylic emulsions, polyurethane dispersions. This type of lacquer is applied to protect the leather and, depending on the additives, to impart certain properties.
  • temperature and humidity affect the aloe vera coating, eg the topcoat.
  • the aloe vera particles lying on the boundary layer of the coating are released from the hard layer matrix and reach the skin of the wearer, where they can develop their curative and / or nourishing effect. Over the wearing period, the hard layer matrix is repeatedly rubbed off, so that new, fresh aloe vera particles always come to rest on the surface and are available for leaching out.
  • the invention relates to a process for producing a coated leather, which is characterized in that the leather by means of spraying, roller coating or printing (eg screen printing) with a solution of a matrix material containing Aloe vera Particles, coated and the matrix material is then cured or dried.
  • spray-dried aloe vera particles are used for the matrix.
  • the amount of aloe vera used in preparing the matrix is about 5-20% by weight, preferably 7.5-10% by weight.
  • the hard-layer matrix or the water-insoluble matrix material used for the coating may contain additional constituents and additives, e.g. conventional paint auxiliaries, such as thickeners and defoamers, pigments, etc., which are required to achieve other properties of the surface coating of the leather.
  • paint auxiliaries such as thickeners and defoamers, pigments, etc.
  • the invention also has the advantage that there is no danger of microbial contamination, since the aloe vera particles are firmly embedded in the matrix.
  • the contact with water is unproblematic, since only those particles can be removed from the matrix, which lie on the surface.
  • the invention further relates to a bracelet, in particular leather bracelet, which comprises a leather as described above, and the use of such a leather as a lining leather for a bracelet, in particular a watch band.
  • the aloe vera concentrate powder was obtained from J.H. Muller, Hamburg, DE.
  • the remaining ingredients were obtained from Stahl Holdings bv, Waalwijk, NL.
  • the hardmesh matrix solution was applied to the leather by screen printing (sieve 68) and allowed to dry at room temperature.
  • the hard-layer matrix coating felt smooth and formed a homogeneous transparent layer that did not detach from the leather even when folded and rubbed against each other by the folded surfaces.
