    摘要： This invention relates to processes for the production of mono- and multifilaments and also staple fibers of multifilaments based on polyarylene sulfides, preferably substantially linear polyarylene sulfides and, more preferably, substantially linear poly-p-phenylene sulfide by melt spinning, multistage stretching and optionally crimping and setting.As a result of the treatment by blowing of air onto the stabilized spun filaments in the first stretching stages at temperatures .ltoreq.100.degree. C. (preferably in stretching baths, more particularly in boiling water), the chain molecules are oriented; the orientation and crystallinity required for high strengths is achieved by afterstretching (in hot air) at elevated temperature. The residence times in the first stage required for effective stretching in accordance with the invention can only be varied within relatively narrow limits in order subsequently to achieve the calculated orientations and effects, particularly high strengths, crystallinities and densities. Overly long residence times at temperatures above 100.degree. C. result in elongation of the material with no additional orientation and hence with an inadequate increase in strength.To increase crystallinity and strength in the production of mono- and multifilaments, multistage stretching may be followed by a thermal aftertreatment; in the staple fiber process, the material is additionally crimped, set (in the absence of tension) and cut. Where an aerodynamic crimping nozzle is used, as is preferably the case, stretching has to be carried out in accordance with the invention in such a way that the fibers are left with sufficiently high shrinkage which is important for crimping and subsequent processing. Crimping is improved by setting in the absence of tension. Relatively high-tensile fibers with sufficiently high residual crimping for subsequent processing are obtained.Textile-denier fibers (up to about 20 dtex) having hitherto unknown strengths of >6 cN/dtex, preferably >6.2 cN/dtex and, more preferably, >6.4 cN/dtex are claimed.
