摘要：The invention concerns a method for preparing cellulose microfilaments,consisting in: preparing a cellulose solution (C); extruding the latter through the hole(s)of a die (1); said die (1) hole(s) having such diameter that in the absence of drawing thesaid solution (C) passing through said die hole(s) produces filaments with a yarn count T0not more than 2.5 dtex; hydraulically drawing, at the outlet of said hole(s), said extrudedsolution; said drawing being carried out with a liquid (F) capable of regenerating orprecipitating, at least partially, said cellulose. The invention also concerns the preparationof microfibres from the resulting microfilaments. The invention enables the preparationof highly hydrophilic cellulose microfilaments and microfibres (with yarn count less than0.7 dtex) and also, directly and continuously, microfilament and microfibre nonwovenfabrics.
