93results about "Composite leathers" patented technology

Engineered leather substrates, methods of making the substrates, engineered leather composites including the substrates, and articles of manufacture which include the engineered leather substrates or composites are disclosed. The substrate includes leather, non-leather fibers, a binding agent and one or more additional components such as cushioning agents, softeners, processing aids, and colorants. A composite material can be formed including the substrate and one or more additional layers, such as top coat layers, reinforcing layers, and cushioning layers. The substrate and or the composite can be chemically or mechanically embossed. The leather used to form the engineered leather substrate can be derived from post- industrial and / or post-consumer materials. The non-leather fibers can be organic or inorganic, and the composition can also include inorganic fillers, such as calcium carbonate, and clays. The cushioning agents can include polymeric microbubbles, foam, rubber particles, and other low density cushioning agents. The binding agents can be synthetic or natural, such as synthetic latex, natural latex, PVA, and starch.

A method of manufacturing a heat and pressure consolidated laminate is provided that includes in superimposed relationship a core layer containing a plurality of cellulosic sheets impregnated with a thermosetting resin, and a decorative layer consisting essentially of a leather material.

The invention discloses a processing method of a leather material, comprising the following steps of: (1) pre-processing an animal skin into a semi-finished product of the leather material with the thickness of 0.7-1.3mm; (2) cutting the semi-finished product of the leather material into a plurality of layers of skins by utilizing a leather-splitting process; (3) forming scraping pulp for a binding surface of an elastic auxiliary material according to required elasticity so that the elastic range of the formed elastic auxiliary material is identical with that of the split leather material; (4) adhering the binding surface of the split leather material and the binding surface of the elastic auxiliary material at high temperature with a substance containing natural emulsion; (5) placing theadhered leather material into water for cleaning, and washing the scraping pulp for forming in the adhering process; and (6) placing into water again and heating to 45-90 DEG C, adding a softening agent and plant protein oil in the heating process, then adding a water-washing resistant agent, and dewatering and airing. The processing method of the leather material has the advantages of favorable elasticity of the obtained leather material, water-washing resistance and simple and convenient processing procedure. The invention also discloses the leather material.

The invention relates to a method for manufacturing a decorative element (100) having a raised embossed visible surface (2). According to said method, an embossing device (4) having a female embossingdie (41) and a male embossing die (42) and at least one decorative material layer (1) are provided. Said decorative material layer (1) is disposed between the female embossing die (41) and the male embossing die (42) such that a visible surface of the decorative material layer (1) faces the female embossing die (41), and a backing surface (3) of the decorative material layer (1), opposite the visible surface (2), faces the male embossing die (42). The embossing is then carried out using the embossing device (4) such that the decorative material layer (1), after embossing, has a raised region(21) on the visible surface (2) and an opposite recessed region (31) on the backing surface (3). In order to stabilize the raised region (21), an insert element (5) is inserted in the recessed region(31). The invention further relates to a decorative element (100) manufactured according to the said method.

A heat and pressure consolidated laminate, and method for producing the same, is provided that includes in superimposed relationship a decorative layer consisting essentially of a leather material, an underlay layer, a substrate, and an optional backer layer. The substrate has a first surface and a second surface opposite one another. The underlay layer includes one or more cellulosic sheets impregnated with a thermosetting resin, and is disposed between the decorative layer and the first layer of the substrate. The backer layer includes one or more cellulosic sheets impregnated with a thermosetting resin, and is disposed contiguous with the second surface of the substrate.
