Abstract

The invention relates to a leather composite, comprising at least two composite parts (2), which are characterized by a layer structure that comprises: a leather layer (3) produced from a hide or a layer of artificial leather; a leather dressing (4) applied to a leather surface of the leather layer (3) or to a sanding base; and at least one electronic layer (7), which is inserted into the leather dressing (4) or applied to the leather dressing (4). At least two composite parts (2) are mechanically sewn to one another, with mutually facing surfaces (9, 10) of the leather dressing (4) and/or of the electronic layers (7), along at least one seam (8) of a connection (1, 20, 30), the electronic layers (7) of the composite parts (2) additionally forming at least one common electrical contact in at least one contact region (13) of the connection (1, 20, 30), which contact region (13) has a greater distance (A) from a visible surface (5) of the leather composite than the seam (8) does.

Abstract

The invention relates to a method for producing a thin grain split (4) and/or flesh split (6) split from a hide (1), the following steps being carried out: making the hide (1) available; splitting the hide into the grain split (4) and the flesh split (6); and tanning the split grain split (4) and/or flesh split (6), characterized in that a solidification layer (7) is applied to the grain side (2) and/or onto the flesh side (3) prior to splitting the hide (1), said layer giving additional mechanical strength to the hide (1) during splitting.

Abstract

The invention relates to a method for producing leather (1) with a textile/ nonwoven layer (2). The invention is characterized in that the following method steps are carried out: producing a leather layer (3) from an animal skin, said layer having a grain side (4); applying and in particular adhering the textile/nonwoven layer (2) on the grain side (4) of the leather layer (3); and spraying a finish (8) onto the textile/nonwoven layer (2), said finish optionally partly penetrating the textile/nonwoven layer (2).

Abstract

The invention relates to a production method (HV) for producing finished leather (FL) for covering components with leather, wherein the following method steps for processing a leather hide (LH) are performed on a raw hide (RH) as an initial product for producing the finished leather (FL) as an end product of the method: mechanical method steps in which the leather hide (LH) is processed using mechanical tools, and chemical method steps in which the leather hide is processed using chemicals, wherein both mechanical and chemical modes of action are combined in individual method steps. In a method step of re-tanning, synthetic and/or vegetable tanning materials, fattening agents, microencapsulated additives based on ammonium, phosphate, phosphor, and the ester compounds thereof and natural additives based on rubber and milk products are used, and in a method step of reducing the leather thickness, the thickness of the leather hide (LH) is reduced by splitting and/or scraping without reducing the physical authenticity, and in a method step of fire retardant application, an application material (AM) comprising acrylic, polyurethane, and vinyl acetate dispersions and having a fire retardant based on cyclical di- and triphosphates, and organic ammonium having sulfur and phosphor compounds is applied on the flesh side (FS) of the leather hide (LH).
