Method for producing protein-polyacrylonitrile spinning solution, by means of reaction of protein grafting with acrylic acid nitryle, whereby potassium persulphate is present as the initiator of the grafting process, characterised in that the used protein is the solution of technical gelatine produced through extrusion by heating from detanned and dechromed waste material from chrome-tanned skins, at a concentration of 5-10 percent and a temperature of 40-70 degrees, directly from extruded material, whereby the grafting is carried out at a monomer to gelatine weight ratio of 3.5 - 1.5:1 in a solution of zinc chloride at a concentration of 55-70 percent, in a presence of 4-6 weight percent of potassium persulphate with respect to dry gelatine mass.
