Process for the production of synthetic linear fibers or threads with improved

Textile properties

The invention relates to the improvement of textile properties of wet-spun thermoplastic fibers or filaments by changes in normal or customary spinning conditions. In particular, the invention relates to a method for improving the textile properties of wet-spun "flame-retardant acrylic fibers or threads which are processed into fabrics or textile goods .

With the introduction of synthetic fibers or threads in technical use, a number emerged
