Definitions

  • the invention relates to a spinning device for producing fine threads by splitting according to the preamble of the main claim.
  • Fine threads into the range below 1 micrometre ( ⁇ m) can be produced by splitting a thread-forming fluid flow as a melt, solution or in general as liquids which are subsequently made to solidify, as has been described in DE 199 29 709 and DE 100 65 859.
  • the mechanism of thread formation is fundamentally different from all the spinning methods which have become known to date where the spinning material is withdrawn by winding-up devices from the spinning nozzles to form threads or, in the case of spunbond methods, by accompanying airflows which exert a force on them and, in a special embodiment, in the so-called meltblown methods, where the air drawing the thread emerges right beside the spinning nozzle openings heated to approx. spinning material temperature.
  • the thread speed thereby achieves that of the winding or is below that of the air- or gas flows drawing it.
  • Nanoval method also termed Nanoval method.
  • the Nanoval method is carried out in lines of nozzles in its industrial applications, a series of spinning orifices being located above a gap.
  • the gas in general air, without particular conditioning after its production in fans or compressors (the energy requirement is fundamentally low compared with the meltblown methods) flows at both sides of the line of nozzles in constant acceleration towards the narrowest cross-section of the gap which then again generally rapidly widens, basically however has the configuration of a Laval nozzle. Also individual round nozzles were described surrounded by an annular gap which constantly reduces towards the narrowest cross-section.
  • a further influential factor for the production of fine and ever finer threads is the throughput per spinning nozzle opening, irrespective of whether with round or slot-shaped openings for the spinning material.
  • the gas speed in the narrowest cross-section of the Laval nozzle can achieve the speed of sound, thereafter in the widened section even into ultrasound, which then, in the case of this flow laden with threads, generally leads rapidly to subsonic sound by means of compression shocks.
  • only a specific shape changing operation can be performed by the shear stress forces in the case of a given running surface of the still deformable thread material.
  • the throughputs are consequently fundamentally lower when producing very fine threads in the range around and below 1 ⁇ m. This leads to the fact that, for a specific total throughput when producing nonwovens according to the Nanoval method for finer threads, more spinning nozzles are used over the width. This applies correspondingly in the production of yarns.
  • the object underlying the invention is to produce a device for producing fine threads which is compact and constructionally simple, a good start to spinning being intended to be possible.
  • the device for producing fine threads has at least one spinning nozzle part which is equipped with spinning nozzles and at least one partially plate-shaped gas nozzle part with at least one gas supply chamber, the at least partially plate-shaped gas nozzle part having a plurality of funnel-shaped depressions as acceleration nozzles into which the spinning nozzles engage in such a manner that combinations of spinning nozzles/acceleration nozzles, in particular Laval nozzles, with rotationally symmetrical gas flow channels are formed
  • the device can be constructed compactly with a large number of closely adjacent combinations, gas nozzle part and spinning nozzle part being displaceable relative to each other so that the gas flow channels which are formed between gas nozzle part and spinning nozzles of the spinning nozzle part can have different flow cross-sections, as a result of which the height of the spinning openings can be adjusted to the narrowest cross-section of the acceleration nozzles, in particular Laval nozzles.
  • a particularly simple construction is provided if the gas chamber is formed between the underside of the spinning nozzle part, out of which the spinning nozzles or spinning nipples protrude, and the upper side of the plate-shaped region of the gas nozzle part, the gas, usually air, being supplied to the acceleration nozzles via said gas chamber.
  • An advantageous embodiment although somewhat more complex and in particular when supplying “cold” air, resides in configuring the gas nozzle part as a hollow body which is engaged by the depressions and the cavity of which between the depressions forms the gas chamber, the hollow body having openings which are directed towards the spinning nozzle part, preferably rotationally symmetrically about the depressions, via which the air or the gas passes towards the acceleration nozzles.
  • a plurality of nozzle parts and gas nozzle parts can be disposed adjacently, different spinning materials also being able to be spun.
  • a further plate with openings can be disposed below the plate-shaped region of the gas nozzle part, forming a distributor chamber for a further fluid.
  • This fluid can be water for coagulating dissolved fibre materials, coolant for freezing the molecular orientation achieved during the splitting, means for heating, e.g. steam, for a second stretching or the like.
  • FIG. 1 a longitudinal section through a first embodiment of the spinning device according to the invention corresponding to the section lines D-D according to FIG. 2 ,
  • FIG. 2 a section of the device according to the invention according to the section lines C-C of FIG. 1 ,
  • FIG. 3 a section through a part of the device according to the invention according to a second embodiment corresponding to the section line A-A in FIG. 4 , and
  • FIG. 4 a section through the device corresponding to the section line B-B in FIG. 3 .
  • the spinning device represented in FIGS. 1 and 2 has a spinning nozzle part 28 in which a plurality of melt channels 14 is provided, said melt channels being provided via a filter 25 and a perforated plate 26 for cleaning supplied melt or solution with melt or solution.
  • the melt channels continue into spinning nozzles or spinning nipples 23 , only three rows of spinning nipples 23 being shown here.
  • a plurality of spinning nipples can perfectly well be provided in succession in the direction of travel according to arrow 50 .
  • the lower plate-shaped region of the spinning nozzle part is received in a gas nozzle part 27 which comprises a frame-like edging 34 and a plate-like part 35 , in the latter three respectively offset rows of Laval nozzles 36 being provided corresponding to the rows of spinning nipples 23 .
  • the edging 34 is provided with an upright edge, a seal 33 being disposed between this upright edge and a surface 32 , which is situated opposite said upright edge, of the lower region of the spinning nozzle part 28 .
  • the spinning- and the gas nozzle part 28 , 27 are aligned relative to each other such that the tip of the spinning nipples 23 protrudes into the Laval nozzles 36 , a gas chamber 22 being formed between the lower surface of the spinning nozzle part 28 and the upper surface of the plate-shaped region 35 of the gas nozzle part, through which gas chamber the spinning nipples 23 engage and which is connected to gas or air supply lines 20 provided in the edging.
  • the spinning nipples 23 are preferably provided with a heating means 24 , advantageously with a belt heating means, as is known from injection moulding tools in plastic material machine construction.
  • the device according to the invention has means for displacement of the spinning- and gas nozzle part 28 , 27 relative to each other, a screw 29 being guided, in the present embodiment, in a split nut 30 which is securely connected to the spinning nozzle part and is connected in an anchor 31 in the frame 34 of the gas nozzle part 27 to the latter, the anchor 31 being able to exert a pressure or tension force according to the direction of rotation of the screw 29 , as a result of which the gas nozzle part is displaced.
  • a split nut 30 which is securely connected to the spinning nozzle part and is connected in an anchor 31 in the frame 34 of the gas nozzle part 27 to the latter, the anchor 31 being able to exert a pressure or tension force according to the direction of rotation of the screw 29 , as a result of which the gas nozzle part is displaced.
  • other types of displacement means are possible.
  • the gas nozzle part 27 is raised, i.e. displaced upwards in FIG. 1 , as result of which the seal 33 is relieved of pressure. If, after arrival, the gas 21 is supplied via the supply line 20 , a pressure force on the seal 33 is increased by the pressure in the gas chamber 22 in addition to a displacement of the gas nozzle part 27 downwards. Hence a specific self-adjustment of the seal is produced upon arrival of the melt or solution and release of the Laval nozzle cross-section towards the individual spinning nipples.
  • the gas supply 21 is switched off, the gas nozzle part 27 is raised until the plate part 35 abuts against the spinning nipples 23 with the wall of the Laval nozzles 35 .
  • the air present in the region of the seal 33 and the surface 32 is thereby blown out.
  • the nipples 23 protrude out of the Laval nozzles and can be cleaned.
  • the device represented in FIG. 3 has a spinning nozzle part 1 with a series of raised portions or projections, preferably in conical form, which receive or form the spinning nozzles 13 .
  • the spinning nozzle part can be configured as a plate into which the spinning nozzles 13 (similarly to FIG. 1 ) are inserted.
  • the spinning nozzles have melt or solution channels 14 which end in a spinning nozzle opening 3 .
  • a gas nozzle part 2 which is configured for example as a hollow body which is formed by two plates provided with funnel-shaped depressions. Between the plates, a cavity 9 is formed which is interrupted by the funnel-shaped depressions. The cavity 9 serves as gas chamber which is in turn connected to a gas supply source.
  • an annular opening 4 is incorporated, the openings 4 represented in section in FIG. 3 being intended corresponding to FIG. 4 in common for adjacent funnel-shaped depressions, i.e. in the embodiment, the funnel-shaped depressions are disposed closely adjacently.
  • the conical raised portions which form the spinning nozzles 13 engage in the depressions of the gas nozzle part 2 such that rotationally symmetrical gas flow channels 5 are produced.
  • yet another insulating formed part 11 is introduced which forms an air gap 12 and extends up to the spinning opening 3 so that the gas flow channel 5 between the surface of the formed part 11 and surface of the depression in part 2 is formed around the space 9 .
  • the respective gas flow channel 5 is thereby configured such that it tapers in the direction of the respective spinning opening 3 around which the respective depression engages rotationally symmetrically.
  • a Laval nozzle is produced, the cross-section of which widens abruptly at the edge between depression and outer surface of the lower plate in FIG. 3 , which however can also take place gradually.
  • the spinning nozzle part 1 and the gas nozzle part 2 are displaceable relative to each other, viewed according to FIG. 3 , in the perpendicular direction, which can be achieved by sliding rods, not shown. Consequently, the height of the narrowest position 6 of the Laval nozzle can be adjusted relative to the spinning opening 3 , as a result of which the start of spinning can also be facilitated.
  • These sliding rods can absorb force produced at the same time with different expansions of the spinning nozzle- 1 and of the gas nozzle part 2 , as a result of which the positioning of both parts relative to each other is maintained.
  • FIG. 4 two rows of combinations of spinning nozzles 13 and Laval nozzles, ending at the narrowest cross-section 6 are represented, the spinning nozzles 13 of one row being offset relative to those of the other rows. It is possible in particular with greater spinning beam widths that special gas distribution channels are also provided between adjacent rows in order to supply the required gas quantities to the Laval nozzles.
  • the mode of operation is dealt with in the following.
  • the melt is supplied in part 1 and emerges in the spinning nozzle openings 3 , whilst the gas, subsequently termed air, flows out of the space 9 in part 2 after emergence via the annular opening 4 towards the channel 5 , which is rotationally symmetrical relative to the spinning nozzle opening 3 , between part 1 and 2 towards the narrowest cross-section 6 and in advance grips the emerging thread 7 at the spinning opening 3 , accelerates it, i.e. reduces it in diameter and, according to the Nanoval effect, causes it already in the Laval nozzle or shortly thereafter to burst into a thread bundle 8 like a brush.
  • the gas subsequently termed air
  • the part 2 Whilst the start of spinning with a line of nozzles takes place simply by pushing together two channel halves which form the Laval nozzles, this is not possible in the case of nozzle combinations in a plurality of rows.
  • the part 2 can however be displaced in the direction of the thread emergence axis. As a result, it can be entirely drawn back when starting spinning towards the formed part 11 , an expulsion of spinning air via the openings 4 can initially be stopped or permitted to a small extent. Then the part 2 is lowered, spinning of the thread is started, it is drawn and made to burst according to the setting data known from the method for the air speed from the applied pressure in the space 9 of part 2 , for the flowing spinning material from the openings 3 and at the temperature of the spinning material required for splitting.
  • the formed part 11 is configured such that it, on the one hand, forms the inner wall of the rotationally symmetrical channel 5 for constant acceleration of the air until close to the spinning nozzle opening 3 but, via an air gap 12 , also insulates the spinning nozzle 13 with respect to heat against the airflow in the flow channel 5 .
  • the formed part 11 can however also contain heating means of the spinning nozzles instead of the spinning nozzle part 1 .
  • the two basic positions of the movable part 2 are indicated in FIG. 3 , in dotted lines for the start of the spinning process.
  • FIG. 4 shows a horizontal section B-B (in FIG. 3 ) as section through a multirow nozzle device for two rows of nozzles in order to illustrate the air supply from the exterior to the individual spinning nozzles 13 for supply from the space 9 via the openings 4 into the channels 5 which end respectively at the smallest cross-section 6 .
  • main distributor channels can be fitted between the nozzle openings, only the rows of individual nozzles moving apart slightly in the nonwoven running direction because the spinning nozzle device according to the invention has the advantage as spinning beam at the same time that it forms a plurality of spinning beams in succession viewed in the nonwoven running direction.
  • Each has its specific irregularities, even from hole to hole, as in the case shown here with spinning nozzle and Laval nozzle beyond the nonwoven width.
  • a statistical compensation for greater nonwoven uniformity can take place between the individual rows because the threads of the following rows increasingly cover the sparse positions of the preceding ones.
  • this medium can easily be introduced as third fluid flow between the spinning and Laval nozzles and be made to flow out.
  • This is illustrated in FIG. 1 by a plate 37 which is provided with openings 38 respectively below the spinning nipples 23 and the Laval nozzle-like openings 36 .
  • the third fluid flow can be introduced into the space 41 formed between the plates 35 and 37 . It passes from there via the upper edges of the openings 38 into the thread air flow.
  • the device is also fundamentally suitable for spinning different spinning materials in the individual spinning nozzles, for which purpose the melt- or spinning solution distribution must be correspondingly arranged, i.e. alternating transversely relative to the direction of travel or also differently from row to row. It is hence possible to produce mixed nonwovens in order to achieve special effects, such as the spinning of binding threads in matrix threads, e.g. polypropylene as binding threads and polyester as the matrix which provides strength or by means of a portion of more greatly shrinking threads in order, after the nonwoven deposition, to achieve higher volumes and softness as a result of shrinkage of the entire thread web and also other nonwoven properties by means of two or more different components.

  • bicomponent or multicomponent threads can be produced without difficulty by supplying two or more spinning materials into the spinning nozzle part and into the channels 14 .
  • a different type of mixed nonwoven can be produced.
  • the present device has in addition the advantage that it connects the melt-guiding spinning nozzle parts 1 or 28 to the colder gas nozzle parts 2 or 27 , in fact in a mutually displaceable manner but securely transversely relative thereto.
  • part 1 After heating part 1 with heating means, not shown here, part 1 will expand more relative to 2 if no particularly heated air is supplied from part 2 so that respectively spinning boring 3 and narrowest cross-section 6 show deviations over the width and length, the same is true for parts 28 and 27 .
  • the connection can take place by means of sliding rods, not shown, which prevent this deviation with respect to the forces, said sliding rods being able to be disposed in the plates of the spinning nozzle part 1 and of the gas nozzle part between the combinations of spinning nozzle/Laval nozzle.
  • heating of the air flow in the flow channel 5 can however also be undertaken intentionally.
  • Guiding part 1 which is initially set back relative to the spinning boring opening 3 , and later is displaced in the running direction of the thread 7 in order to produce the splitting effect, must take place by means of guides or sliding rods which are known in tool construction.
  • the introduction of air likewise not shown here, takes place from the exterior to the front, rear or side on the spinning beam, a seal requiring to be present between spinning nozzle part 1 and gas nozzle part 2 or because a few millimetres of guidance length between 1 and 2 suffice, the chambers 9 shown in FIG. 4 can also be fed via corrugated bellows around the spinning beam and an outer distribution chamber.
  • spinning beam of a larger width into a plurality of nozzle fields, these in turn comprising numerous individual spinning nozzle/Laval nozzle combinations so that individual ones of these packets (spinning packs) can be exchanged in the case of blockages of the spinning openings or other disruptions.

  • the polymer throughput was changed in regions as reproduced in Table 1, likewise the air pressure and hence the flowing air speed in the region of the shear stresses on the thread leading to splitting.
