Definitions

  • the invention relates to a process for producing high-strength polypropylene fibers with high strength and low elongation by continuous shrink spinning, drawing off, stretching and cutting fiber strands to form the polypropylene fibers.
  • the fiber strands are passed directly into a water bath after spinning for the purpose of cooling and then drawn in a drawing zone with a high drawing ratio of up to 10: 1.
  • the relatively rapid cooling of the fiber strands in the water bath results in a relatively high degree of preorientation in the edge region of the individual fibers, with the result that they are difficult to stretch.
  • the known method is also only suitable for relatively coarse fibers with a single titer in the range of greater than 3 dtex. manufacture. The higher friction effect on the individual filaments caused by the water bath alone does not allow the spinning of fibers with finer titers.
  • a polypropylene fiber is known from EP 0 535 373 A1, which shows a necessary fineness with high strength, but can only be produced in a complex two-stage process.
  • the fiber is temporarily stored after spinning and drawing, with additional treatment by impregnation.
  • the fiber strands are then taken up again in a second stage, dried and cut.
  • Another object of the invention is to provide an apparatus for performing the method.
  • the invention is characterized in that, on the one hand, the low melt temperature during spinning in conjunction with a slow take-off speed favors a partial molecular orientation of the undrawn fibers and therefore a higher strength of the fiber is established. Due to the slow withdrawal speeds, significantly lower internal tensions between the polymer chains in the filaments occur during the Cooling process after spinning.
  • the subsequent drawing in three successive drawing stages taking into account that 70% of the total drawing is already introduced into the fiber in the first drawing step, enables a steady slow polymer crystallization to be produced in the fibers, so that in addition to the high strength, a low residual elongation and a corresponding one Fineness in the fibers.
  • the partial stretching of the fiber strands is carried out higher in the second stretching stage than in the subsequent third stretching stage.
  • the total drawing takes place in the drawing stages with a decreasing drawing ratio.

  • the drafting rollers of the middle drafting systems are preferably designed to be heatable in order to obtain a uniform and continuous temperature control of the fiber strands during drawing.
