Definitions

  • the threads and fibers obtainable by this process have an excellent water absorption capacity and have a round to trilobal cross-sectional shape in the spun material, but this does not occur during the aftermath treatment mostly collapsed into star-shaped to playful profiles.
  • the main influencing factors which change the cross-sectional shape are the stretching, drying and steaming process. Fibers with such strange cross-sectional profiles can give rise to fluffy and hairy yarns, rough handles or increased short fiber content due to breakages in the yarn during further processing into textile structures.
  • the present invention was therefore based on the object of producing hygroscopic fibers and threads with largely uniform round to oval fiber cross sections which maintain their profile during the aftertreatment of the spun material and which are therefore easier to process into textile structures.
  • the spinning process is carried out so that the non-solvent essentially does not evaporate in the spinning shaft and is washed out of the solidified threads after spinning.
  • Substances that meet these requirements are e.g. polymeric compounds from the series of polycarbonates, polystyrenes, polyvinyl acetates and cellite derivatives.
  • threads and fibers are obtained from hydrophobic polymers which, in addition to the desired uniform round to oval cross-sectional profiles, have a water retention capacity of at least 10% and a core / shell structure in which the core is highly microporous, the pores predominantly with one another are connected and the sheath surrounding the core is substantially more compact than the core, but is penetrated by channels which allow the access of liquids to the pore system of the core.
  • Threads and fibers with such core / shell structures include described in the aforementioned DE-OS 25 54 124 and in DE-OS 27 19 019.
  • the present invention therefore relates to those threads and fibers which are characterized in that they have uniform round to oval cross-sectional profiles.
  • Another important advantage of the present invention is that such fibers not only no longer have the disadvantages mentioned at the outset, but that they additionally have a very stable pore system which is far less sensitive to packaging processes such as steaming, ironing and the like. Furthermore, the additives spun in increase the water retention capacity, which contributes to the comfort properties of such fibers.
