Abstract

Method for production of collagen material for surgical use, in which Achilles tendons or hides are digested with alkali and after an acid treatment they are mechanically processed, expanded, cross-linked and dried, wherein one digests the Achilles tendons or hides with alkali until the amide nitrogen content is 0.15 to 0.30 micromoles per gram and after a salt acid treatment and washing to a pH value of 2-4 the thickness of the expanded collagen mass is reduced under pressure during formation of a two- dimensional network, and then the individual lengthwise oriented fibres are exposed by hackling, and then after performing an expansion in familiar fashion, the fibres are cross-linked with hexamethylenediisocyanate in presence of a non-ionic or cationic emulsifier and these are dried and further processed on textile machinery to form nets or sheetlike materials.
