Abstract

This invention relates to flexible cellulose fibers with a reduced modulus and a decreased NMR degree of order, particularly for use in the textile field, which are obtained by pressing out solutions of the cellulose in hydrous NMMNO through spinning nozzles along an air travel into an NMMNO-containing aqueous and/or alcoholic precipitation bath as well as by a conventional rinsing, aftertreatment and drying, with strengths of between 15 and 50 cN/tex, and to a process for their production. According to the invention, these flexible cellulose fibers have an initial modulus of less than 1,500 cN/tex, and the relationship of the heights of the lines at 88 ppm and 85 ppm above the spectrum base line in the highly resolved 13C-NMR solid-body spectrum is </=1. Furthermore, these flexible cellulose fibers are obtained by means of a process in which specified hydrophilic, low-molecular weight, organic additives, which are soluble in the polymer solution and have mainly nitrogen-containing groupings are added in defined amounts to the spinning solution of the cellulose as well as to the precipitation bath.
