Abstract

A process for obtaining an opaque, fibrillated and hollow structure, comprising the steps of preparing a formulation of a solution containing a cellulose ester dissolved in a solvent consisting essentially of a non-solvent liquid which is miscible with the solvent of said cellulose ester, and an organic solvent co-miscible with said cellulose ester; passing the solution of cellulose ester to an extrusion orifice located in the narrowing of a venturi, or above it, venturi through which a coagulation liquid is passed, said coagulation liquid being a non-solvent of said cellulose ester, whereby a precipitate is obtained in the form of a cellulose ester fibreta.
