Abstract:
A full-grained milled napa leather is provided on its grain side with a dressing formed from a solidified plastics dispersion. Required leather properties are still ensured and the production process is substantially simplified and more economical. First, the leather, such as cowhide, is subjected on a mechanically untreated grain side to a milling process for at least two hours. This results in a typical napa structure with a natural pebbled grain. Then, a polyurethane dispersion is applied to the grain side containing pigment particles and optionally further additives. Then the hide is allowed to dry. The solidified dispersion forming the dressing has a thickness of, preferably, from 0.05 mm to 0.07 mm.
Abstract:
The leather has a finish on a buffed surface. The finish layer is formed in a plurality of layers including an outer layer with a given hardness and a particular surface effect preformed in a hot substrate having a structure corresponding to the particular surface effect the outer layer being formed of a solidified, cross-linked, hydrolysis-resistant, lightfast, polyurethane-containing dispersion, and having a thickness of between 0.01 and 0.08 mm, and an inner layer bonded to the buffed surface leather and comprising a solidified, highly crosslinked, hydrolysis-resistant, lightfast, polyurethane-containing dispersion and having a hardness less than a hardness of the outer layer.
Abstract:
An athletic shoe, such as a soccer shoe, has an upper defining a toe region, an insole connected to the upper, and an outsole secured to the insole. A vamp in the toe region is joined to the insole. The vamp is a full-grain leather composed of a grain layer and a leather fiber layer joined to the grain layer. An elastomeric coating is disposed on and partway penetrates into the leather fiber layer in a region where the fiber layer is joined to the insole. The coating has a thickness above the surface of the leather fiber layer of at least 0.1 mm. The coating may also be disposed in a region adjoining the region where the fiber layer is joined to said insole. The coating may also be reinforced with an embedded reinforcement.
Abstract:
A dressed leather comprises a split leather having one side from which fibers protrude, a first layer of a solidified aqueous dispersion having a thickness between 0.07 mm and 0.22 mm of a synthetic plastics material in which the fibers are completely immersed on the one side, a second layer of a synthetic plastics material of generally the same thickness as the first layer bonded to the first layer and having turned away therefrom a textured surface, and a finish layer overlying the textured surface of the second layer. The split leather is substantially free of the dispersion except at the fibers.
Abstract:
A foamed material, which is adapting under pressure to the shape of parts, particularly of parts of the human body, but which on pressure relief again returns to a vast extent and after a certain restoring time into the original shape, consists of the following constituents:(a) substantially saturated liquid hydrocarbons;(b) unsaturated liquid hydrocarbons, preferably polybutadiene;(c) a reactive agent, preferably polyisocyanate, with which the unsaturated liquid hydrocarbons are reacted;(d) a cross-linking agent, for example ethylene hexane diol;(e) hollow microspheres, the thin shell of which consists of vinylidene chloride copolymer and the interior of which contains a gas.The production of such a foamed material is preferably such that the substantially saturated liquid hydrocarbons and the unsaturated hydrocarbons are intermixed, noting that particles consisting of a vinylidene chloride copolymer and containing an inflating agent are added to this mixture or to a constituent of this mixture, and noting that the mixture is, prior or after this addition, heated to a temperature between 92.degree. C. and 165.degree. C. and preferably 105.degree. C., so that hollow microspheres are formed in situ, and that subsequently the cross-linking agent is added and that finally, after optionally adding a catalyst, the mixture is combined with the reactive agent and intensely mixed, whereupon the mixture is filled into a mold and allowed to react.
Abstract:
A user interface method, including presenting by a computer executing a user interface, multiple interactive items on a display. A first sequence of images is captured indicating a position in space of a hand of a user in proximity to the display, and responsively to the position, one of the interactive items is associated with the hand. After associating the item, a second sequence of images is captured indicating a movement of the hand, and responsively to the movement, a size of the one of the items is changed on the display.
Abstract:
In order to create a full grain napa cowhide which exhibits the characteristics with respect to grain pipeyness and water vapor permeability that are required by the automotive and upholstery industries, a finish is applied to the grain side of the full grain leather. The finish includes a pigmented layer with a thickness of between 0.015 mm and 0.04 mm and is formed of a stabilized polyurethane and/or polyacrylate dispersion. The dispersion contains microspheres with a diameter of less than 45 &mgr;m, which form primarily closed cells, and at least 10% open cells by volume. The top side of the layer is provided with a napa embossing. A second layer, placed on the first layer, is formed from a cross-linked polyurethane-based varnish application containing a dulling agent. The leather undergoes a milling treatment.
Abstract:
A dressed leather is provided at least on one side with depressions and have on this side absorbent protruding fibres. At this side the leather is bonded with a layer formed of an aqueous dispersion of synthetic plastics material, said layer fills the depressions and completely receives the protruding fibres and forms at least a part of the dressing, which dressing is provided with a structured surface at the side turned away from the leather.Preferably, the dressing consists of two layers, the inner layer, which is adjacent the leather and completely receives the protruding fibres, is formed of the aqueous dispersion of synthetic plastics material and the outer layer, which has the structured surface, consists of an aqueous dispersion of synthetic plastics material or of a liquid solution of synthetic plastics material.
Abstract:
A substrate having an appearance similar to that of nubuk-leather or pile-leather, respectively, or of a textile pile consists of a textile carrier body being at least partially impregnated with a, preferably cross-linked, polymeric synthetic plastics material consisting of a foam which has open cells formed by introducing air and optionally has closed cells formed of hollow microspheres. The textile carrier body consists of a fleece or of a knitting, preferably of a crimped fleece of synthetic fibres, which is needled together with a knitting or with a fleece, strengthened by thermal embossing, in such a manner that the fibres extend through the knitting. The knitting may consist of a roughened stockinet, i.e. a stockinet having opened loops. The carrier body is ground at least at its one impregnated surface and is thus rough and can be provided with a coating.
