Definitions

  • the invention relates to a spinning machine for the continuous production of extruded filaments by a wet spinning process with or without an air gap, with at least one pair of rollers whose axes are inclined to one another and which has a wet zone in the axial direction for the thread coming from a spinneret or a coagulation bath which connects to a drying zone.
  • the wet zone comprises an area of thread consolidation and an adjoining area of deacidification by washing.
  • the drying zone includes a heated roll area.
  • the angular position of the roller axes leads to constant distances between the thread turns, e.g. B. 6 mm over the entire length of the roller.
  • the large thread spacing is of crucial importance in the entire wet area because this prevents the thread turns from sticking together.
  • Due to the large thread spacing in the drying area the rollers must be particularly long because a certain heated path length in the roller contact is necessary for drying. A particularly stable thread run is just as important as measures to prevent the individual thread turns from sticking together, for example by thread guide elements.
  • the invention aims to design the thread transport over a pair of rollers along a helical thread track with variable lateral winding spacing in such a way that, without additional thread guide elements, both compliance with in the wet area the side safety distance required for the aftertreatment section (e.g. in the case of filaments with 110 dtex approx. 4-6 mm) as well as its continuous reduction in the drying area to the required minimum is made possible, resulting in reduced roll lengths, which among other things also improve the usability entails a corresponding economic use of drying energy and at the same time optimal production speed can be guaranteed.
  • This is achieved in that the axes of the pair of rollers enclose an angle to one another both in a vertical reference plane and in a horizontal reference plane.
  • the angle in can be determined by determining Coordination with the roller diameters and the center distance a thread course can be achieved in which the winding distances in the wet zone are large and z. B. continuously reduce to the drying zone.
  • the pair of rollers Due to the winding distance on the pair of rollers, which decreases from 6 mm at the beginning of the wet zone to 0.5 mm in the drying zone, a better efficiency in the course of the process can be achieved on a pair of rollers with a shorter overall length and lower energy consumption, in particular for the roller heating. It is expedient if the pair of rollers is designed as a main and auxiliary roller and the auxiliary roller has a smaller diameter than the main roller approximately 1: 2 to 1: 4. A diameter ratio of 1: 3 or 1: 4 is particularly advantageous. In practice, an arrangement has proven to be particularly advantageous in which, with the horizontal axis arrangement of one roller, for example the main roller, the axis of the other roller, e.g. B.
  • auxiliary roller the main roller axis crosses in vertical projection at about a third of its length in the area of the wet zone and the coordinates of the axle bearing positions of this roller, e.g. auxiliary roller, differ from the coordinates of the axle bearing positions of an arrangement of a roller, e.g. auxiliary roller parallel to the main roller, in both coordinate directions .
  • At least one of the rollers of the pair of rollers can be designed to rise conically towards the drying zone over a portion of its axial length, preferably the area of deacidification.
  • the other roller usually follows, e.g. B. the auxiliary roller, in its diameter configuration on a proportional scale to the shape of the main roller.
  • FIG. 1 shows a view of a main and an auxiliary roller with an indicated thread course
  • Fig. 2 shows the front view of this with coagulation bath and spinneret
  • Fig. 3 shows a plan of Fig. 1, but only the roller axes.
  • a viscose thread 1 is formed according to FIG. 2 in a coagulation bath 2 by means of a spinneret 3.
  • the thread 1 is pulled up from the bath 2 with coagulant and carried in turns over a main roller 4 and an auxiliary roller 5.
  • the main roller 4 comprises a wet part 6, which extends over approximately three-quarters of its length, and a heated drying part 7.
  • thread hardening takes place in an acid phase 8 and then deacidification in a washing phase 9.
  • the axis 5 'of the auxiliary roller 5 is inclined in the vertical plane through the axis 4' of the main roller 4 to the axis 4 '(FIG. 1) and additionally rotated out of the vertical plane (FIG. 3).
  • the inclination of the axis 5 'against the horizontal axis 4' can be seen in Fig. 1, the rotation of the axis 5 'with respect to the axis 4' is shown clearly in Fig. 3 in the plan of the axes. 2 also shows the axes, namely the main roller axis 4 'in point projection and the auxiliary roller axis 5' in a skewed position. This arrangement leads to the thread course indicated in FIG.
  • the main roller 4 and optionally the auxiliary roller 5 can be slightly conical (increasing in the direction of the drying phase). This conical area can be restricted to zone 9, which extends approximately from the crossing point 10 of the axes 4 ', 5' to the heated drying zone 7.
  • the diameter of the main roller 1 is approximately 180 mm and that of the auxiliary roller approximately 50 mm.
  • the auxiliary roller end point of the axis 5 'on the dry part side comes in a position of approximately 136 mm below the main roller axis 4' and approximately 61 mm on the left, the end point of the auxiliary roller 5 on the coagulation bath side in a position of about 113 mm below the main roller axis 4 'and about 52 mm to the right, both based on the original common roller plane (vertical plane).
  • the crossing point i. H.
  • the lateral spacing of the first of the helical windings in region 8 of FIG. 1 is approximately 9 mm at 110 dtex and decreases continuously in order to be 0.8 mm in the last windings in region 7.
  • the required crossing angle of the roller axles must be adapted to the titer to be spun depending on the roller diameter and the roller spacing.
  • the surface temperature of the drying part and thus also the energy requirement required for this can therefore be significantly reduced with a comparable space requirement with regard to the roller arrangement and the same spinning speeds due to the extended contact time in the drying area.
  • the roller pairs according to the invention several of these devices can also be arranged one above the other in a particularly space-saving manner while maintaining ease of use when piecing or changing bobbins.
  • the textile data of the spun yarns correspond to the value level customary for yarns (continuous yarns) produced in a continuous process.
  • the spinning machine has been tested for viscose processes and is suitable for wet spinning processes with or without an air gap in general, including solution spinning processes, as well as for NMMO processes.
