Method for the storing of elastan filaments with coarse tires

Elastan filaments with a titre of at least 2,500 dtex according to the wet spinning method were disclosed for the first time in laid-open print DE 198 290 63 A1. Coarse titres of this kind, which are present in tape form with tape widths of typically approx. 2 to 10 mm and are found in the typical application areas of natural rubber threads, are very attractive economically. Areas of use are, for example, elastic undertapes for upholstery fabrics, base material for underwear, leg borders for lingerie and bathing articles, and special hygiene articles in the medical sector. There is described a method for the storing of elastan filaments with a titre of at least 2,500 dtex in drums with a filament line length of at least 10 km with the use of a displacing device, in which the filaments are stored meandering in layers, and in which the filaments are inlaid into the drum at a speed of at least eight per cent above the production speed of the filaments.
