A process for extracting collagen fibres from tissue obtained from animal skin that allows to obtain collagen fibres with high physical and mechanical characteristics necessary for causing its transformation into yarn and fabric by using common plants of the textile industry. The process provides the steps ofpretreating a skin tissue, unravelling the pretreated skin tissue obtaining a mass of loose fibres; tanning the fibres obtained from the unravelling step; treating the tanned fibres and sending the treated fibres to a spinning step. In particular, the unravelling step provides the steps of: introducing in an aqueous solution pieces of said pretreated skin tissue; circulating the aqueous solution the pieces against at least one unravelling roller, frictioning the pieces against said roller, whereby fibres in suspension are gradually formed in said solution, up to forming a product in a bath made completely of loose fibres, i.e. a mass of loose fibres.
