PCT No. PCT/EP97/00693 Sec. 371 Date Aug. 25, 1998 Sec. 102(e) Date Aug. 25, 1998 PCT Filed Feb. 13, 1997 PCT Pub. No. WO97/30198 PCT Pub. Date Aug. 21, 1997Cellulose fibres and filaments are prepared from a spinnable, cellulose-containing solution containing 94-100 wt. % cellulose, water, and phosphoric acid and/or anhydrides of phosphoric acid. The resulting cellulose fibres and filaments have an elongation break point greater than 7%. The cellulose-containing solution used to prepare the fibres and filaments may be either isotropic or anisotropic. The cellulose-containing solution is coagulated in a liquid containing water and cations, and the cations are preferably monovalent. Fibres and filaments prepared in this manner are especially suitable for use in textiles.
