    摘要： The invention relates to a process for the production of hydrophilic filaments or fibres having a sheath/core structure, a porosity of at least 10% and a water retention capacity of at least 10% and having a fibre swelling factor which is lower than the water retention capacity. The process is carried out by spinning a solution of a fibre forming synthetic polymer, especially an acrylonitrile polymer by the dry jet wet-spinning method wherein immediately on leaving the spinning jet and prior to coagulation in the precipitation bath the filaments or fibres are contacted with steam or with the vapor of another liquid which coagulates the filaments.

    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.

    摘要： A process for the dry spinning of synthetic polymers, in particular polyacylonitrile fibres, from solutions in high polar solvents, such as dimethylformamide, which are heated to 100.degree.-150.degree. C. shortly upstream of the spinneret and spun there by spinnerets having a certain shape, and in the spinning cell the specific energy supply is at least 0.090 kWh per m.sup.2 of heated cell area, the cell is charged with at least 70 m.sup.3 (S.T.P.) of hot air per hour, and the filaments are treated in the lower part of the cell with water or aqueous preparations, so that the temperature of the filaments which leave the cell is decreased below 110.degree. C. Under these conditions, the unexpectedly high spinning cell outputs of at least 20 kg of PAN solid per spinning cell per hour can be achieved without yellowing or self-ignition of the filaments occurring.
