Definitions

  • the invention relates to a method for finishing pile fabrics, in particular carpet pile, for cleaning, stretching, glossing and possibly permanent fixing of the pile, the pile side of the fabric being subjected to repeated repeating brushing and walking stresses and an edge moving on a web and a device for performing the method for finishing pile-bearing fabrics.
  • calenders are known in finishing technology for pile-bearing fabrics which improve the surface of pile-bearing fabrics.
  • Masking of the pile fiber with polymers is known in particular for animal pile. The scale layer of the animal fiber is thus embedded and the willingness to felt is reduced or avoided.
  • cross-bridging i.e. sticking between individual pile fibers cannot be avoided.
  • This formation of cross bridges affects the quality of the pile-bearing fabrics, especially in the case of knotted carpets.
  • the invention has for its object to provide a method and an apparatus for finishing pile-bearing fabrics, wherein a cross-bridge formation, that is, a sticking of the pile fibers is avoided and the fibers, in particular knotted carpets, are cleaned and the wastewater pollution that has previously occurred when finishing carpets is reduced becomes.
  • the procedural task is solved in that the pile-bearing tissue is moved on a curved path, the radius of curvature of which is opposite to the curvature of the path of the card.
  • the pile-bearing fabric follows the curvature of the transport roller, the pile, in particular the individual rows of a carpet that are knotted, being opened such that they protrude radially from the transport roller in the radial direction.
  • the edge of the work roll can rip into these gaps and mechanically clean the pile thread and smooth the surface when brushing past the pile-side surface of the fabric.
  • the processed fabric then reflects the light in such a way that it shines. At the same time, the fabric is protected from further soiling.
  • the advantageous effect on the fabric can be further enhanced if the edge is moved on a circular path and the pile-bearing fabric is brought into contact with the track of the edge on a track that changes the curvature several times and / or the pile-carrying fabric is heated.
  • Heating is particularly advantageous if the pile is also wetted with a liquid before it is stressed by the edge.
  • Wetting with a suitable polymer protects the fiber from dyeing under the influence of various reagents, makes the fiber durable, dirt-repellent and long-lasting.
  • a flush preferably with air, frees the tissue from loose fibers and supports the masking of the fibers.
  • a device is suitable for carrying out the method, which preferably has a plurality of transport rollers resting on the work roller and the pile-bearing fabric has a curvature in the contact area corresponding to the transport roller.
  • one roller is arranged with its axis fixed in space and the other is designed to be movably attached under force.
  • the movable roller can then deflect, so that overloading of the roller drive or excessive stress on the pile-bearing fabric is advantageously avoided.
  • the walking stress of the pile-bearing fabric is supported if the transport rollers have the same diameter and / or the surfaces of the transport rollers are designed to be elastic with a high coefficient of friction, in particular to have a felt-like padding.
  • This configuration not only serves to improve the advance of the fabric, but also prevents overloading of the roller drives and excessive stress on the fabric.
  • At least one, preferably smooth, introduction roller and / or a roller for metered wetting of the pile-bearing surface in the transport direction of the pile-bearing fabric before the first line of contact between the work roller and the first conveyor roller of the fabric is arranged.
  • a brush roller has proven to be particularly effective for wetting the pile-bearing surface, which, if necessary, removes the wetting liquid from a metering roller immersed in the wetting liquid. The individual bristles of the brush make it possible to work the liquid into the pile threads.
  • the productivity of the machine increases if the work roll is heated and / or consists of a metallic material with a smooth surface.
  • the smooth surface prevents the wetting liquid from sticking to the work roll.
  • the edge is worked into the work roll as a groove.
  • the stress on the device is advantageously reduced by a spiral groove.
  • the guidance of the pile-bearing fabric is improved if at least two grooves are machined into the work roll, the pitch angles of which in the longitudinal direction are identical and opposite to the circumferential direction.
  • the advantages achieved by the invention consist in particular in that the arrangement of the work roll with the adjacent transport roll exerts a flexing effect on the pile-bearing fabric located therebetween. With this flexing effect in connection with the curvature of the pile-bearing fabric, a mechanical separation of the individual pile fibers is achieved, at the same time the pile-carrying fabric is cleaned and loose fibers are removed. Immediately afterwards, the pile fiber masking hardens as it passes the work roll.
  • FIG. 1 shows a schematic side view of the device according to the invention for sealing pile-bearing tissues.
  • the pile-bearing fabric 1 encloses a first transport roller 2 over part of the circumference with the fabric side.
  • a brush roller is arranged - not recognizable in the drawing - which takes a liquid from a metering roller, also not shown.
  • the brush roller impregnated with a chemical liquid transfers the liquid, which is used to mask the pile fibers, in doses to the fabric.
  • the pile-carrying fabric is inserted into the gap between the introduction roller 12 and the transport roller 2 and moved by the first conveyor roller 2 in the transport direction 8, so that the pile-carrying fabric 1 reaches a first flex zone, which is extends along the line of contact 3 between the work roll 4 and the first transport roll 2.
  • the pile-bearing fabric 1 is subjected to a flexing effect.
  • the work roll 4 rotating at high speed in the direction of rotation 9 supports the transport of the pile-bearing fabric 1 in the direction 8.
  • grooves 11 incorporated in the work roll 4 increase the flexing effect and thus support mechanical separation and cleaning of the schematically indicated pile fibers 5 at the first contact line 3
  • the peripheral speed of the work roll exceeds the transport speed of the fabric by more than a hundred times.
  • the fabric is therefore swept over 200 times from the edge of the groove during its contact with the work roll.
  • the convex curvature of the material fed in towards the pile side fans out the individual fibers and thus additionally facilitates the mechanical separation and cleaning of the fibers.
  • the pile-bearing fabric 1 comes into contact with the work roll 4 with its pile side.
  • a rise in temperature of the pile fibers is forced by the friction effect and / or heating.
  • Chemical finishing reagents applied beforehand for example with the brush roller (not shown), can thereby begin their curing process.
  • the pile-bearing fabric 1 emerges from the processing zone in which it is in contact with the work roll 4.
  • the end moves tension-free towards the transport roller 7, where it is gripped by the transport roller 7 and forms a relief zone a second contact zone 6 between the work roll 4 and a second transport roll 7 is supplied.
  • the relief zone remains intact because the transport rollers are driven synchronously.
  • a flexing effect is exerted once more in the flexing zone 6 and the mechanical separation and cleaning of the pile fibers 5 is thus achieved.
  • the free circumference of the work roll 4 is shielded from thermal insulation 16.
  • the transport roller 7 is spatially fixed.
  • the work roll 4 is designed to be movable in the direction of the arrow 17 and can be locked in its free end position.
  • the work roll 4 bears against the transport roll 7 with a preselectable force. This force can either be a component of gravity resulting from a corresponding preloaded spring. In this way, pile-bearing fabrics of different thicknesses can be processed without overloading the roller drives or stressing the fabric excessively.
  • the distance between the rollers adjusts itself automatically to the fabric to be processed.
  • transport roller 2 is designed to be movable in the direction of arrow 18. It also bears against work roll 4 with a preselectable force.
  • the insertion roller 12 is designed to be movable in the direction of the arrow 19.
  • the transport rollers 2, 7, 15 have an approx. 5 mm. strong felt-like coating, while the work roll 4, and preferably also the feed roller 12, are equipped with a smooth surface, preferably made of metal.
  • a smooth surface preferably made of metal.
  • two grooves 21 are incorporated, the edges 22 of which exert the effect described on the pile fibers 5 in. If the grooves 21 are made in a helical fit with the opposite angle of inclination, then it is evened out; Working moment advantageous. Overall, however, this also results in a reduced sound emission and less vibration in the operation of the entire device
  • Dust and loose pile fibers are removed directly by the suction device 13.
  • the fabric In the suction flow, the fabric is flushed with air, which additionally supports a cross-bridge-free masking of the fibers.
