Claim Text:
1. A manufacturing method for producing finished leather for covering components with leather, wherein the following process steps for treating a leather hide are performed on a raw hide as an initial product for producing the finished leather as an end product of the method: mechanical process steps in which the leather hide is treated using mechanical tools, and chemical process steps in which the leather hide is treated with chemicals, wherein both mechanical and chemical modes of action are combined in individual process steps, wherein the chemical process steps include a step of retanning using synthetic and/or vegetable tanning materials and fattening agents and microencapsulated auxiliary agents and natural additives, wherein the microencapsulated auxiliary agents comprise ammonium, phosphate, phosphorus and ester compounds thereof, and wherein the natural additives comprise rubber and milk products; and, wherein the mechanical process steps include a step of reducing the thickness of the leather hide, the leather thickness of the leather hide being reduced by splitting and/or scraping without reducing the physical authenticity, and wherein the chemical process steps include a step of applying a flame retardant using an application material and a flame retardant, wherein the application material comprises acrylic, polyurethane, and vinyl acetate dispersions, and wherein the flame retardant comprises cyclic diphosphates, triphosphates, organic ammonium, sulphur compounds, and phosphorus compounds, wherein the flame retardant is applied on the flesh side of the leather hide; and wherein, in the step of retanning, the microencapsulated auxiliary agents are encapsulated with casein or melamine.
