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： 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.

摘要： Provided are leather fibers for yarn. The leather fibers forming the yarn are obtained from cowhide. An amount of the leather fibers having an H value of 30 or more is 30% by weight or more of a total leather fibers contained in the yarn. The H value is defined by the following Equation 2: [Equation 2] H=L/D where L: leather fiber length, and D: leather fiber thickness. A thickness index (M) of the leather fibers satisfies Equation 1: [Equation 1] M=D1/D2≤60 where D1: an average thickness of 0 fibers having a highest thickness in 1 mg of leather fibers, and D2: an average thickness of 10 fibers having a lowest thickness in 1 mg of leather fibers.

摘要： In a grain leather (1) in whose grain layer (2) defects (3) formed by indentations are present, these defects are corrected by pressing an aqueous, if appropriate lightly foamed, plastics dispersion which comprises very small compact particles into these indentations by means of an application roll, as with a knife coater, and then drying the leather (1), whereupon the surface (4) of the grain layer (2) is subjected to a pressure and heat treatment at a temperature of at least 100° C. by means of a pressure roll rolling on the surface. During this procedure, a plastics compound in which hollow microspheres (5) formed from the compact particles are present and which completely fills the indentations forms in the indentations.

摘要： 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 nullm, 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.

摘要： A powdered leather which is composed of at least 85% by weight of cortex, at most 2% by weight of oil and fat, and at most 0.5% by weight of Na.sup.+ and Ca.sup.2+ ions capable of being eluted by water and which has an average particle size (D.sub.50) of at most 7 .mu.m, a standard deviation of the average particle size being at most 3 .mu.m. With this powdered leather, it is possible to thin films, coatings, fibers, etc. which would hardly be deteriorated with time. The powdered leather is produced by providing a powdered leather raw material, grinding the raw material into coarse particles, drying the coarse particles, defatting the dried coarse particles using a solvent, removing the residual solvent from the defatted coarse particles, rinsing the resultant coarse particles, dewatering the rinsed coarse particles, swelling the dewatered coarse particles in steam, redrying the swelled coarse particles, pulverizing the redried coarse particles, classifying the pulverized particles into fine powder and coarse powder, and repulverizing the fine powder so as to have an average particle size (D.sub.50) of at most 7 .mu.m.
