摘要:
The invention relates to a method for producing leather pellets, to a method for producing compound granules from leather pellets and a polymer material, and to the use of such compound granules for producing molded parts or films. Said leather pellets are produced through the following steps: Shavings, crust leather remnants and finished leather waste are obtained as waste products in leather production and finished leather processing; the shavings, crust leather remnants and finished leather waste are milled into ground leather stock comprising leather fibers; the ground stock is pressed into leather pellets; and the leather pellets are dried to a residual moisture content of no more than 30% by weight. The leather pellets can be mixed with a polymer material at a ratio of 10-95% by weight and bonded to one another and shaped forming compound granules as another intermediate product. Said compound granules can be used to produce molded parts by means of injection molding or films by means of calendering.

A woven fabric comprises a plurality of first fibers extending along a first direction, the first fibers having a first modulus of elasticity; a plurality of second fibers extending along a second direction and being woven with the plurality of first fibers, the second fibers having a second modulus of elasticity that is lower than the first modulus of elasticity; and a coating disposed over the plurality of first fibers and the plurality of second fibers. In some embodiments, the coating is a synthetic leather.

Lederabfälle werden zuerst in Streifen oder Stücke zerschnitten oder zerquetscht. Das Zerreißen der Lederstücke oder -streifen kann in schnell rotierenden Trommeln mit Messersätzen erfolgen. Schließlich werden die Einzelfasern vom Feinmaterial abgetrennt. Die so hergestellte Ledergrundmasse besitzt ähnliche Eigenschaften wie Leder. Zusätzlich kann sie aber je nach Anwendungszweck mit weiteren Eigenschaften versehen werden. Durch die Verwendung von Abfallmaterial ist die hergestellte Ledergrundmasse billig.

Methods and systems for processing coverings such as leather hides and fabrics are provided. A system can include a worktable having a surface on which a covering is placeable. An imaging device can be positionable relative to the worktable. The imaging device can be configured to obtain an image of the covering on the surface of the worktable. A projector can be positionable relative to worktable. The projector can be configured to project an image onto the surface of the worktable and the covering on the surface of the worktable. A controller can be in communication with the imaging device and projector. The controller can be configured to correct images taken by the imaging device. The controller can also be configured to correct the images projected onto the surface of the worktable and the covering thereon. The controller can be configured to permit the showing of virtual markings on the covering placed on the surface of the worktable through an image projected thereon by the projector. The covering can then be marked or cut along the virtual markings.

The present invention regards a process for making a solid product (18) starting from hides. The process comprises a step of arranging a sheet-like element (1) in hides, a cutting step, in which the sheet-like element (1) is cut into a plurality of cut-outs (2), a step of wetting the cut-outs (2) with water, and a mixing step, in which the cut-outs (2) are mixed with a glue (9) comprising natural resins, in order to obtain a mixed product (10). In addition, the process comprises a pressing step, in which the mixed product (10) is pressed in order to obtain a pressed semifinished product (13), and a solidification step, in which the glue (9) of the pressed semifinished product (13) solidifies in order to obtain a solid product (18) with low environmental impact and adapted to be employed in many different applications, as in the clothing field, construction field and furniture/interior design field, etc.
