Abstract
FIELD: production of artificial leather replacing natural one in traditional fields of its application. SUBSTANCE: methods include washing, grinding, alkali and acid treatment of collagen-containing raw material of animal origin with subsequent washing in water, separation of fibers of collagen-containing raw materials in aqueous medium, producing of homogeneous paste of collagen by mixing the paste of fiber-separated collagen-containing raw materials with preliminary fiber-separated wastes of tanned leather with mass ratio of fiber-separated wastes of tanned leather and fiber-separated untanned collagen-containing raw materials of animal origin equalling from 1:9 to 9:1, in terms of dry matter; introduction, if required, of filler and special-purpose additives; introduction of cross-linking agent; cryostructuring of collagen paste at minus 2-40 C, defrosting and drying with subsequent formation, if required, of coating; and also various collagen-containing materials produced by these methods. EFFECT: higher efficiency.
