Definitions

  • the invention is in the field of spinning technology and relates to a method and a device according to the preambles of the corresponding independent Claims.
  • the method and device are used to manufacture Staple fiber yarns that consist at least partially of man-made fibers, i.e. from Staple fibers made from synthetic or chemical-technical processes natural polymers are made.

That of yarn formation previous refinement can also be called opening by dissolving one Fiber association can be achieved.
  • the fiber material fed to the spinning process becomes previously usually removed from bales, cleaned and / or if necessary mixed and in preparation steps depending on the fiber material (carding, Combing, stretching, etc.) into one for a specific spinning process and for one specific end product brought into a suitable form, usually in a form in which the fibers only adhere to one another by adhesive or frictional forces and already have a preferred, parallel orientation in the longitudinal direction.
  • the fiber bales manufactured by, for example, in a primary spinning process Extrusion from spinnerets creates quasi endless filaments that this Filaments for aligning the macromolecules stretched and fixed and in a variety can be combined into a cable that can be cut out of the cable or tearing (converting) flakes of staple fibers and that these flakes are pressed into bales.
  • the further treatment of the fiber material then essentially corresponds to the sequence of pretreatment outlined above, Refinement and yarn formation.
  • the staple fibers created in this way are dependent on the manner in which the cables are cut all substantially the same length (rectangular stacking diagram) or similar to natural fibers in a range varying lengths.
  • a simpler method for producing staple fiber yarns from man-made fibers is the so-called direct spinning.
  • the in a primary spinning process by, for example, extrusion and stretching produced, almost endless filaments in a variety to a cable summarized.
  • the cable is fed to a device in which the filaments torn or cut and the resulting fiber structure by stretching is refined.
  • the resulting longitudinal fiber structure is then used directly for yarn formation fed.
  • Such methods have over those mentioned above Processes using fiber bales have the advantage that they are significantly simpler.
  • the parallel arrangement of the filaments in the cables is during the conversion in maintained essentially, that is, by converting the filaments
  • the resulting staple fibers hardly need to be parallelized for yarn formation become.

  • the filaments are advantageously stretched and, if necessary, stretched out fixed in such a way that the macromolecules at least partially in the filament direction aligned and held in this orientation.
  • the at least partially drawn filaments can be essentially random or in a predetermined Patterns are filed.
  • a spunbonded web has various methods known per se. Filaments made of a thermoplastic polymer are made, for example, by pressing between appropriately heated flat pressing agents, i.e. thermally hardened.
  • the separation of the nonwoven fabric in spunbonded nonwoven tapes is carried out, for example mechanical cutting means performed. By cutting arise on the Long edges of the spunbond tapes of fiber ends (at other points of the There are no such fiber ends in spunbond tapes).
  • When separating the Spunbonded care must be taken to ensure that the fibers are not pulled out of the ribbon and the fiber ends are preferably not welded together.
  • the Length and length distribution of the staple fibers present in the spunbonded nonwoven tapes are directly dependent on the width of the spunbonded ribbon and on the type of Filaments are deposited in the spunbond. The narrower the spunbonded ribbon, the shorter will be the fibers; the more orderly the filament tray, the more uniform it becomes Be stack length.
  • the alignment of the staple fibers in the spunbond nonwoven is also depending on how the filaments are deposited. Since the fiber ends are all at the Long edges of the spunbonded ribbon is a high degree of alignment Longitudinal fibers are not possible. The fineness of the spunbonded ribbon is determined by the spunbond density and the ribbon width.
  • spunbond tapes before the yarn is formed, they are envisaged yarn formation, in particular rotation, and depending on Yarn to be produced is drawn in a drafting system or with the help of an opening roller resolved, as is known for conventional staple fiber materials. If necessary, the spunbonded tapes for feeding are for refinement suitable means to compact. With the refinement, the solidification of the Spunbonded structure at least partially dissolved. If this solidification is sufficient is strong or if the pinch point distance is shorter than the majority of the fibers it is also possible to stretch the spunbonded nonwoven to insert the macromolecules into the Parallelize fibers further.

  • strong connections between the filaments do indeed require high stretching forces, but allow for refinement by stretching next to one Fiber parallelization also involves fiber stretching or molecular alignment for example, can be thermally fixed in the yarn state.
  • blended yarns from various man-made fibers for example, filaments made of different materials are already in the primary spinning process Materials created and essentially stored together are different Spunbonded and brought together or laminated (doubled) or become the secondary Various spunbond tapes are fed to the spinning process at the same time.

  • the spunbonded nonwoven tape according to FIG. 3 is made from a spunbonded nonwoven in which the filaments are only roughly arranged.
  • the spinnerets are in turn moved transversely to the direction of removal of the spunbond, the speed of the movement resulting from the movement of the spinnerets and the removal rate being less than the speed at which the filaments are ejected from the primary spinning device. This results in a fiber length distribution in the spunbonded nonwoven ribbon, which lies between the fiber length distributions of the ribbon according to FIGS. 1 and 2.
