Definitions

  • the invention relates to a device and a method for the hydrodynamic consolidation of nonwovens, fabrics and knitted fabrics, comprising a solidification system with at least one water beam and a drum or an endless belt, between which a fibrous web is transported and solidified.
  • the underlying drum under the fiber web has a plurality of openings, in the one hand, the fibers can partially enter and are entwined with each other, and on the other hand, the water of the water jets is sucked or removed. Usually 2-3 water bars are arranged one behind the other. Without compaction, the fiber web is very sensitive to the water jets or the suction. The fibers would be displaced, which would adversely affect the appearance of the fibrous web as well as the strength and elongation. The hydroentanglement of chemical fibers such as polyester or polypropylene is limited possible without compaction. Care must be taken very carefully to ensure the correct pressure, the distance of the water bar from the fiber web and the associated suction power.
  • the DE 102008033252 A1 shows a system for processing continuous filaments, in which immediately behind the filing of the filaments on a conveyor belt, a first preconsolidation takes place, and the filaments are only then compacted and hydraulically solidified.
  • the DE 10 2009 016 996 A1 and the EP 1126064 A2 disclose a method of hydrodynamic consolidation of a fibrous web, wherein compaction takes place prior to hydroentanglement between a covering band and a diverting pulley.
  • the US5,098,764 discloses compacting a fibrous web between a pulley and the drum prior to a first hydroentanglement.
  • the apparatus for the hydrodynamic consolidation of nonwovens, fabrics and knitted fabrics comprises a solidification system with at least one water bar and a drum or an endless belt, between which a fiber web is transported and solidified.
  • a compacting device in the direction of the fiber web before the water bar, a compacting device is arranged, which compresses the fiber web on the drum or the endless belt.
  • the compacting device has at least one Kompaktierblech that presses the fiber web on the drum or the endless belt.
  • Kompaktierblech that presses the fiber web on the drum or the endless belt.
  • Kompaktierblech can be attached to the water bar, creates a very compact unit with which the fiber web is first compressed and then solidified by high pressure water jets. Due to the short sequence between compaction and solidification, there are advantages for the strength of the fiber web, at the same time preventing blurring of the individual fibers, which leads to a better nonwoven product.
  • the water jet can have a pressure of 10 to 100 bar. Optimum values are achieved with a pressure of 20 to 40 bar.
  • the attachment of Kompaktierbleches on a support allows on the one hand a retrofittable solution that can be attached to the water frame on the machine frame.
  • the distance of the compacting device can be set to the fiber web.
  • the compacting device can be adjusted by means of a pivoting device on the carrier in the angle and in the position, so that the pressing force of the Kompaktierbleches can vary on the nonwoven web. With the pivoting device, the distance from the outlet edge of the Kompaktierbleches can be adjusted to the water jet row of the water bar.
  • a further improvement is achieved in that the Kompaktierblech compressed under bias the fiber web.
  • the bias voltage can be generated by the elasticity of the Kompaktierbleches and / or by a contact pressure device.
  • the design of Kompaktierbleches made of resilient metal or plastic produces a low-cost and very efficient compacting device, as spring back in material irregularities of the slightly bent sheet metal or plastic strip.
  • the use of the elasticity of the bent Kompaktierbleches created a certain inlet area, which is very complicated by the prior art produced by angularly disposed endless belts. About this Inlet area, the fibers are compacted and subsequently compacted in the region of the outlet edge of the compacting plate.
  • a decisive advantage of the invention to the prior art is that an outlet edge of the Kompaktierbleches is positioned directly on the water jet. This prevents a partial pulling in of the fiber web into the suction region of the bore or of the suction slots in the drum or under the endless belt. The fiber web is better fixed on the drum or the endless belt, while the individual fibers are entwined with each other. The previously disadvantageous longitudinal strips that occur without compaction can thus be effectively prevented.
  • the outlet edge of the Kompaktierbleches is positioned so close to the water jet, that at least a portion of the suction region of the bore or the suction slots are covered. Only the fibers, which are arranged in the region between the outlet edge of the Kompaktierbleches and water jet row are entwined with each other. The areas of the fibrous web under the Kompaktierblech are held by the Kompaktierblech on the drum. At the same time, only small areas of the fiber web between the outlet edge of the Kompaktierbleches and the water jet row are subject to the negative pressure. This also reduces the unwanted longitudinal stripes.
  • the distance of the front edge to the water jet can be reduced to 0.1 mm, so that a very targeted partial hydroentanglement takes place without stretching the fiber web in the region in front of the water jet rows.
  • a further improvement can be achieved in that the outlet edge of the Kompaktierbleches is designed to slide over the fiber web. It is thus achieved an alignment of the fibers on the surface of the fiber web, whereby an increased longitudinal strength, but no reduction in transverse strength is achieved.
  • the outlet edge of the Kompaktierbleches be formed, to roll over the fiber web.
  • a line-shaped pressure is exerted on the fiber web, in which the influence of the MD / CD ratio is as low as possible.
  • An inexpensive embodiment can be achieved by a Kompaktierblech made of metal, plastic or a composite material. It is advantageous if the materials have a certain elasticity or spring action and bend easily. As a result, an inlet or Kompaktier Scheme is generated in which the fibers are compacted.
  • the Kompaktierblech has a thickness of 0.1 to 3 mm, preferably from 0.15 to 0.5 mm.
  • the necessary bending elasticity is given.
  • the Kompaktierbleche can adjust material irregularities.
  • the spring action is so sufficient that the force is limited to the fiber web and the fiber web is not torn off.
  • the compacting plate may be provided with Teflon or a nano-coating.
  • the outlet edge of Kompaktierbleches has a waveform or teeth
  • the fiber web can be better kept on the drum with strong suction of the drum.
  • the wave shape results in a higher stability, especially with thin sheets, because the outlet edge does not bend or deform partially due to the suction.
  • the outlet edge of the Kompaktierbleches may also have holes or a perforation, can flow through the air, so that the Kompaktierblech not deformed during suction through the suction slots of the drum or the endless belt.
  • the distance of the Kompaktierblech to the drum or the endless belt is adjustable.
  • the distance to the water jet can be adjusted, on the other hand, the bias of the resilient plate can be determined.
  • the inventive method for the hydrodynamic consolidation of nonwovens, fabrics and knitted fabrics in which a fiber web is transported between a water bar and a drum or an endless belt and solidified, characterized in that the fiber web in front of the water bar by means of a compacting device, which is designed as Kompaktierblech , is compressed on the drum or the endless belt. It is thus created a shorter length in the system, which has significant advantages for the fiber web at the same time, as a compacting prevents the fibers from blurring just before the hydroentanglement.
  • the densification of the fibrous web may alternatively be generated by a sliding or rolling compactor, depending on whether a change in MD / CD ratio is desired. Accordingly, the outlet edge of Kompaktierbleches is then designed.
  • the strength of the fibrous web in the longitudinal direction can be increased.
  • the direct solidification of the water bar immediately behind the Kompaktierblech is more effective and thus more economical than a solidification with pre-wetting in an upstream Kompaktierü.
  • a compacting device is integrated into a solidification system in the smallest space, wherein the compaction takes place close to the solidification. This avoids blurring of the fibers, which increases the quality of the fleece and avoids the unwanted longitudinal stripes. Sliding compaction also increases the longitudinal strength without affecting the transverse strength.
  • a solidification plant 1 which essentially comprises a drum 3 or alternatively an endless belt with at least one water bar 4.
  • the drum 3 can be designed as a so-called sieve drum, comprising a perforated metal drum, which is covered with a supporting fabric and a fine sieve or alternatively with a microporous shell.
  • the drum may be formed as a structure drum, the surface of which has a perforation to give the fibrous web 2 a structure or a pattern.
  • the drum 3 has a plurality of bores 3 a, through which the water of the water bar 4 is discharged.
  • a suction pipe 3c is arranged with a plurality of suction slots 3d, via which the water is sucked off with negative pressure.
  • the water bar 4 is arranged, which injects a series of water jets 6 onto the fiber web 2 under high pressure by means of a plurality of nozzles 5.
  • the water bar 4 is operated according to the invention with a pressure of 10 to 100 bar, preferably at a pressure of 20 to 40 bar.
  • the nozzle bar 4 can be operated with one or more rows of water jets 6.
  • the nozzles 5 are arranged along the longitudinal axis of the water bar 4.
  • the fiber web 2 runs in this embodiment in the arrow direction from left to right on the drum 3 and is continuously from the Water jets 6 hit.
  • the water bar 4 is arranged adjustable at a distance from the drum 3 or to the continuous web.
  • a compacting device 10 is arranged in the running direction of the fiber web 2 in front of the water bar 4 and exerts a pressure on the fiber web 2 along the longitudinal axis of the drum 3.
  • the compacting device 10 comprises a suspension 13 with a hinge 12 to which a support 11 is rotatably mounted.
  • the suspension 13 is attached to a machine frame or scaffolding, not shown.
  • a Kompaktierblech 14 is arranged, which is recognizable in side view. In its longitudinal extent or over the working width of the Kompaktierblech 13 extends substantially over the entire length of the drum 3.
  • the Kompaktierblech 14 is secured in the region of a rear edge or inlet edge 14b on the support 11, whereas the front edge or outlet edge 14a below Preload the fiber web 2 on the drum 3 presses.
  • the compacting device 10 can be pivoted via the joint 12, whereby the position of the support surface or the support line of the Kompaktierbleches 14 is adjusted to the fiber web 2.
  • the pressure of the compacting plate 14 can be adapted to the fiber web 2 via the rotation of the compacting device 10 about the joint 12. For this purpose, it makes sense, in addition to the articulated arrangement of the compacting device 10 to make them adjustable in height.
  • the suspension 13 can be made adjustable. Depending on the fibers to be processed so that the pressure or the force acting on the fiber web 2, can be adjusted.
  • the Kompaktierblech 14 may for example be designed from a strip of metal or plastic, which is slightly bent by the pressure of the compacting device 10 and thus resiliently presses on the fiber web 2.
  • the free end or the outlet edge 14a of the Kompaktierbleches 14 points in the running direction of the fiber web. 2
  • the technical effect of the compacting device 10 is that the fiber web 2 is compacted in a very small space before the solidification by the water bar 4 takes place.
  • the system can be made significantly shorter than a compactor with rolls or belts according to the prior art.
  • Another advantage is that the compaction creates a densification of the fibers just before solidification by the water jets, which prevents blurring of the individual fibers, which ultimately leads to a better nonwoven product.
  • Essential for the invention is the compacting close to the water jet 6, which prevents the fiber web 2 is sucked in larger areas in front of the row of water jets 6 and by the negative pressure in the suction pipe 3c in the drum 3 in the production direction and deforms the web becomes. It can create transverse waves in the fleece and longitudinal stripes with uneven intake. At the same time, the strength of the fibrous web 2 in the longitudinal direction may increase, whereas the strength of the fibrous web 2 in the transverse direction remains the same.
  • a change in the MD / CD ratio occurs in both directions, ie, for example, increases in the longitudinal direction, but decreases in the transverse direction, or vice versa.
  • the Kompaktierblech 14 can by the Kompaktier sign shortly before solidification by the Water jets increase the strength in the longitudinal direction of the fiber web 2, since the outlet edge 14a only slides over the surface of the fiber web 2. By contrast, no change in the orientation of the fibers takes place over the entire cross section of the fiber web 2.
  • Another advantage results from the fact that the disadvantageous longitudinal strips or longitudinal structures are prevented by the Kompaktierblech, since the fiber web 2 is pressed in the longitudinal direction of the drum 3 on the drum 3 and only the portion or strip between the Kompaktierblech 14 and the water jets stretched and the fibers are entangled with each other.
  • FIG. 1a is an enlarged view of the solidification area without the arranged in the drum suction pipe 3c shown.
  • the bore 3a has an inlet region 3b, which is arranged in the running direction of the fiber web 2 in front of the water jet 6.
  • the bore 3b of the suction slot 3a is wedge-shaped, so that the suction force increases only slowly by the negative pressure in the suction slot and the unconsolidated web slowly compressed without moving the fibers by suction.
  • the outlet edge 14a of the compacting plate 14 is arranged close to the water jet 6 and at least partially conceals the inlet region 3b.
  • the fiber web 2 is pressed by the Kompaktierblech 14 along the longitudinal axis of the drum 3 on the drum 3. Only the fibers, which are arranged in the region of the bore 3a and the inlet region 3b, are entangled with each other. Only small areas of the fiber web 2, which are located in the region of the inlet region 3b, are drawn into the bore 3a by the negative pressure of the suction.
  • the distance of Kompaktierbleches 14 with its outlet edge 14a of the water jet 6 can be reduced to 0.1 mm, so that very targeted partial hydroentanglement can be achieved without stretching the fiber web 2 in the region of the suction slot 3a.
  • the Kompaktierblech 14 can be arranged with its outlet edge 14a but also with a greater distance to the water jet 6 on the drum 3 or a band. The advantage is then in the space-saving arrangement of the compacting device according to the invention, wherein the strength of the fibrous web can be higher due to the design with the Kompaktierblech.
