Definitions
- the invention relates to a method for producing staple fibers from a crimped sliver according to the preamble of claim 1 and to an apparatus for carrying out the method according to the preamble of the claim
- a generic method for producing staple fibers from a crimped sliver and an apparatus for carrying out the method are known from EP 1 072 704 Al.
- a band-shaped tow is formed from a plurality of individual fiber strands which are each provided individually in cans of a can gate.
- the fiber strands have been produced in an upstream process by melt spinning of synthetic filaments and, after melt spinning, deposited as a fiber strand with a plurality of filaments in one of the cans.
- a crimping of the fibers takes place, wherein the tow is previously brought together from a treatment band width to a narrower crimp band width.
- the crimping band width desired for the crimping of the sliver substantially depends on crimping of each of the guided filaments in the sliver. Too thick and too narrow slivers result in uneven crimping. On the other hand, very thin and wide slivers lead to a considerable outlay on equipment for realizing large working widths in order to be able to carry out stable crimping operations. In that regard, an adaptation of the sliver guide to the respective desired treatments and treatment sequences is required.
- EP 1 072 704 A1 discloses an alternative method and an alternative apparatus for producing staple fibers, in which the tow is brought together prior to drawing and the heat treatment to form a narrower and thicker sliver.
- uniform treatments in particular during conditioning and stretching of the sliver, can not be achieved or only at low production speeds.
- an object of the invention to develop a method for producing staple fibers from a crimped sliver and an apparatus for performing the method of the generic type such that a treatment adapted and favorable in terms of large production management of the sliver is possible.
- Another object of the invention is to improve the generic method and the generic device to the effect that even with the largest bandwidths of the sliver manual operation when starting a fiber line is possible.
- This object is achieved according to the invention by a method in that the individual bands are guided within the treatment bandwidth to several subbands with equal part widths or with different large part widths and that the subbands are merged to the sliver with the Khoffselbandbreite in the range of 700 mm to 1200 mm.
- the trigger means are assigned a plurality of guide means, through which the individual bands within the treatment bandwidth to several sub-bands with equal sections or widths of different sizes are performed and that the band collection means a plurality of the subbands associated deflection by which the subbands are collapsed to the sliver having the crimp width in the range of 700 mm to 1,200 mm.
- the invention is characterized in that, even with the largest treatment hand widths for the treatment of the sliver, there are no excessively large deflections when folding the fiber strands into the crimp width.
- the crimp bandwidth of the sliver in the range of 700 mm to 1200 mm defines an area that requires only a few layers of the subbands to curl the sliver. It has been found that the crimp width in the range of 700 mm to 1200 mm is optimum for increasing the production amount with a view to optimal treatment for stretching with large treatment. tion belt widths of the sliver and uniform Eink Hursel Heidelberg despite large Köselbandbreite of the sliver represents.
- the division of the sliver in individual sub-bands within the treatment bandwidth also allows easier handling at the beginning of the process or process interruption.
- the individual subbands can be performed directly next to each other with the same sections or with different sections.
- the part widths of the subbands are turned off substantially to the later required for the crimping of the sliver ripple bandwidth.
- the fiber strands are preferably guided within the treatment bandwidth with an occupation density of 40,000 dtex / cm to 60,000 dtex / cm. This ensures both a heating of the sub-bands by rolling or by steam chambers and a uniform conditioning of all fibers in the sliver at normal fiber speeds.
- the deflection of the individual fibers to merge the subbands to the sliver can be further improved by two outer subbands are guided, which include the corresponding crimping the subband, so that also a two-layer sliver is formed.
- the subbands can thereby be merged with very little offset to the sliver.
- the erfmdungssiee method is particularly suitable to cut from the sliver, a large amount of staple fiber.
- the method according to the invention can preferably be carried out, in which the sliver has a total titer during the treatments and crimps, which corresponds to an amount of at least 10,000 t of staple fibers per hour. This can achieve significant increases in production over conventional methods and devices.
- the erfmdungswashe apparatus for performing the method is characterized in particular by a high flexibility in the occupancy and management of the sliver.
- the subbands can be guided within their section widths with the same coverage density or with a symmetrical arrangement with uneven density of coverage.
- the crimp means comprises at least one crimp means which crimps the sliver at a coverage in the range of 80,000 dtex / cm to 120,000 dtex / cm.
- the coverage is in view of the crimp selected medium so that all filaments of the sliver receive a buckling to form the crimp.
- crimping means preferably driven crimping rollers are used, which form a nip between them, which extends between the crimping rollers over the entire crimping belt width of the sliver and opens into an adjacent crimping chamber.
- the development of the device according to the invention is preferably used, in which the crimping rollers are assigned a plurality of compensating means which impede a deflection of the crimping rollers.
- the compressive forces acting on the crimping rollers can be absorbed without deformation of the nips.
- the nip has a constant gap height over the entire crimp bandwidth.
- the device according to the invention is preferably designed such that the guide means and the number of cans assigned to the subbands give guidance of the individual bands, in which the individual bands at least one of the subbands with a Part width of at least 700 mm and with a coverage density in the range of 40,000 dtex / cm to 60,000 dtex / cm result.
- the partial width of the sub-band is preferably matched to the Köselbandbreite of the sliver, so that even a two-ply arrangement of the sub-bands the sliver gives the correct configuration for crimping.
- the deflection means of the belt-collecting device are preferably such that the sliver is formed by two layers of subbands, which are to be combined several times. ren in the treatment range of 1,400 mm to 2,400 mm are guided side by side. This makes it possible to realize a matching the K Hurselbandbreite guided the subbands.
- the withdrawal means and the treatment means have draw-off rollers or guide rollers, which have a length in the range of 2,000 mm to 2,500 mm and each have a bearing point on both end faces. Even largest treatment bandwidths of a maximum of 2,400 mm can thus be achieved, whereby the subbands within the fiber path can be guided parallel to one another.
- the take-off rollers or the guide rollers are arranged for this purpose in frame walls.
- the inventive method and apparatus according to the invention are particularly suitable for producing staple fibers, for example based on polyester or polypropylene, in high production quantities.
- the fibers of the sliver can be cut into sections with a length of 3 to 300 mm.
- staple fibers based on polyethylene or polyamide can also be produced.
