    摘要： An elastance spool is described which comprises a winding of elastane threads having a titre of greater than 160 dtex, particularly from 160 dtex to 1400 dtex, and a bobbin weight of elastane threads of at least 1.5 kg, in which the elastane threads have a ribbon-shaped fiber cross-section, wherein the ratio of the width of the elastane threads to the thickness of the elastane threads in cross-section is at least three to one. The elastane spool is used for the production of textile sheet products and for the production of disposable articles of hygiene.

    摘要： Described are a process for producing elastane yarn having a linear density of at least 2500 dtex by the wet spinning process and the thereby producible coarse linear density elastane yarn having a wide cross section and a low residual solvent content. The process comprises the steps of spinning an up to 35% strength by weight stable-viscosity elastane solution into a coagulation bath, washing and optionally drawing, drying by contact heating, setting, spin finishing and winding the yarn, the filaments leaving the coagulation bath passing around a diverting roller disposed just above the coagulation bath liquid, the as-spun filament linear density amounting to not more than 1% of the value of the final linear density, the jet stretch ratio being within the range from 0.5 to 50, the contact heating temperature being at least 220° C. and the contact time of the elastane yarn being at least 2 seconds.
