Abstract

Process and device for the production of fibrous starch materials through extrusion of a dispersion or aqueous solution of starch material in a flow of saline coagulant; in which the dispersion or aqueous solution is extruded through a microporous tubular wall in a chamber circularly ringed with said microporous wall in such a way to obtain an ex-trusion flux of the starch material which surrounds the said tubular walls and the coagula-lion of the extrusion is carried out by feeding the flow of the coagulation agent in the an-nular chamber parallel to the extrusion surface. The said obtained fibres in particular have applications in the paper sector in substitution for or in combination with cellulose fibres.
