摘要:
Engineered animal skin, hide, and leather comprising a plurality of layers of collagen formed by cultured animal collagen-producing (e.g., skin) cells. Layers may be formed by elongate multicellular bodies comprising a plurality of cultured animal cells that are adhered and/or cohered to one another; wherein the elongate multicellular bodies are arranged to form a substantially planar layer for use in formation of engineered animal skin, hide, and leather. Further described herein are methods of forming engineered animal skin, hide, and leather utilizing said layers of animal collagen-producing cells.

Um ein vollnarbiges, an seiner Narbenseite mit einer Zurichtung (3) aus einer verfestigen Kunststoffdispersion bestehenden Zurichtung versehen ist, zu schaffen, bei welchem die erforderlichen Eigenschaften des Leders gewährleistet sind und bei welchem der Herstellungsvorgang wesentlich vereinfacht und kostengünstiger ist, wird vorgeschlage, eine Rindlederhaut mit mechanisch unbehandelte Narbenseite zunächst zumindest zwei Stunden einem Walkvorgang zu unterziehen, wobei sich eine typische Walknappastruktur mit einem Natur-Walknappakorn bildet, und in der Folge auf die Narbenseite eine Pigmentpartikel sowie gegebenenfalls weitere Zusätze enthaltende Polyurethandispersion aufzutragen und anschließend trocknen zu lassen. Die verfestigte, die Zurichtung (3) bildende Dispersion weist eine Stärke vorzugsweise zwischen 0,05mm und 0,07mm auf.
摘要:
A method wherein a floral motif with empty spaces between the elements (2) thereof is placed on a template (1), and separate leather components (3) are prepared such that their outlines match the elements (2) of the floral motif. Each of the various components (3) is joined to the adjacent components at the contact points therebetween via reinforcing members (4), and the empty spaces between said components (3) are filled with a tracery (5) of crossed threads with its end joined to the edges of adjacent components (3). The article consists of discrete components (3) joined together at the contact points between their edges via reinforcing members (4), whereas the empty spaces between adjacent components (3) are filled with a tracery (5) of crossed threads.

Industrielles Verfahren zur Herstellung von Lederhaut durch Wiedergewinnung von Restfragmenten desselben Stoffes, wie - z.B.Ausschnitte, Späne und andere Stücke der Naturhäute, die zur Lederherstellung verarbeitet worden sind.
摘要:
The invention relates to a method and the production of natural leathers from pieces of natural leather torn into different-sized fibers which are sorted and placed, once they have been mixed with a binder, in successive layers (6, 7 and 8) on a support sheet (9) provided with filaments crossing the different layers. The support sheet (9) and filaments (10) are extracted once the binder substance has cured.

摘要:
The invention relates to a method for correcting flaws produced in the grain layer (2) of grain leather (1) by indentations by pressing, by means of an application roller such as a squeegee, into said indentations an aqueous, optionally slightly foamed dispersed synthetic resin which contains miniscule compact particles and then drying the leather (1). The surface (4) of the grain layer (2) is then subjected to pressure and heat at a temperature of at least 100 °C by means of a pressure roll rolling off on said surface, thereby producing in the indentations a synthetic mass in which microspheres (5) formed from the compact particles are present and which completely fills in the indentations.
