摘要 |
<p>The invention relates to a method for producing cellulosic forms, especially fibres and filaments, by a) dissolving cellulose in an aqueous solution of a tertiary amine oxide, especially N-methylmorpholine-N-oxide, and b) extruding the cellulose solution through a moulding tool, over an air gap and into a precipitating bath, the forms separating out. The cellulose solution and/or the precipitating bath contain a tenside. The method is characterised in that step b) is carried out with a cellulose solution and/or precipitating bath tenside content (c) in the region of 100 ppm > c >= 5ppm and an air gap width of between 2 and 20 mm. The inventive method avoids any deterioration or considerable fluctuations in the physical textile properties of the spun fibres or filaments in spite of the reduced width of the air gap.</p> |
