    摘要： The invention relates to a process for the production of polyacrylonitrile tows containing from 7 - 15 % by weight, preferably from 10 - 12 % by weight, of comonomer components from which it is possible to produce yarns having low boiling-induced shrinkage values and yarns and dimensionally stable made-up articles with improved textile properties which comprises reducing the tow-shrinkage emanating from the spinning and stretching process by 80 - 95 % of the original tow shrinkage by heat-fixing and eliminating subsequently the residual shrinkage by fixing with saturated steam.

    摘要： The invention relates to a process for the production of bifilar fibres and filaments consisting of only one acrylonitrile polymer. The polymer is dissolved in a usual solvent and the resulting solution is divided up into two solution streams. After these solution streams have been brought to different temperatures they are spun by a conventional bifilar spinning technique.

    摘要： High-strength filaments of dry-spun polyacrylonitrile are obtained by a process in which tension-reduced spun filaments are continuously stretched hydrothermally in one or more stages: where it involves several stages, stretching is carried out at a temperature of the stretching medium gradually increasing from stage to stage up to .theta.=.theta..sub.n and, in the final (n-th) stage, to a degree of at least 50% of the maximum degree of stretching; where it is carried out in a single stage, stretching is carried out at the optimal stretching temperature .theta..sub.n, after which the material is further treated in the conventional way, optionally with fixing of the stretched material to a pre-determined extent.
