Definitions

  • the invention relates to a system and a method for consolidating and structuring fibers to form a nonwoven according to the preamble of claims 1 and 10.
  • the US 3,088,859 describes a device for structuring a fleece, which is guided between a drum and a circulating belt or between two circulating belts.
  • the object of the present invention is to provide a plant and a method of the type mentioned above, by means of which fibers can be sufficiently solidified and structured.
  • the plant according to the invention for the strengthening and structuring of fibers comprises a first and a second circulating belt which are used for Strengthening and structuring of fibers to form a fleece are at least partially arranged in parallel and thus form a structuring area.
  • At least one band is designed as a counterband with a multiplicity of pattern-forming openings and at least one water bar is arranged within the counterband in the structuring area for the water jet consolidation of the fibers.
  • the invention is characterized in that the structuring area has a length of at least 0.2 m and the counterband between the pattern-providing openings has micro-openings.
  • the counterband between the pattern-providing openings has 3 to 100 micro-openings per square centimeter in a random or regular arrangement. This results in a sufficient strength of the fleece in both directions.
  • the micro orifices have a hydraulic diameter of 0.2 to 0.4 mm. With a smaller hydraulic diameter, the effect of the water jets turned out to be too small. With a diameter of more than 2 mm, the micro-openings act like a structure or pattern. It has been found in particular in the case of fibers with a length of 10 to 40 mm that they are solidified at several points.
  • the at least one water bar is operated at a pressure of 30 to 80 bar, preferably 60 bar. This is significantly less than the known water jet consolidation with 100 to 400 bar for the consolidation of the fibers on a Spunlacetrommel with an open structure shell. Surprisingly, this one has preferred pressure range result in a more uniform and higher consolidation in the machine direction (MD) and in the transverse direction (CD).
  • MD machine direction
  • CD transverse direction
  • At least one further water bar can be arranged upstream and / or downstream of the structuring area in the transport direction, which is operated at a pressure of 10 to 25 bar and solidifies the non-structured top side of the fleece.
  • At least one further water bar which is operated at a pressure of 10 to 60 bar, preferably 15 to 30 bar, and which solidifies the underside of the nonwoven, can preferably be arranged downstream of the structuring area in the transport direction.
  • the structuring area is inclined by 1 ° to 10 ° in the direction of transport. This supports the removal of water from, for example, wet-laid fibers.
  • a further improvement results from the fact that a moistening device is arranged within the structuring area in front of the water bar or bars, which ensures a first stabilization of the fibers.
  • the method according to the invention for consolidating and structuring fibers to form a nonwoven is carried out with a first and a second circumferential band, which are at least partially arranged in parallel and thus form a structuring area, at least one band being designed as a counterband with a large number of pattern-forming openings, between which micro-openings are arranged, the fleece being structured by water jets in the area of the pattern openings and in the area of the micro-openings over a length of at least 0.2 m and is solidified at certain points.
  • the pattern area of around 0.2 m in length with the parallel band guide ensures a sharp image of filigree patterns in the product. This is used to structure a fleece with a pattern-giving surface, but to solidify it between the patterns, creating a very fluffy product due to the step bed effect, which can be used as a cotton pad, wipe or as a cosmetic product (flushable wipe).
  • the invention also relates to a method for solidifying and structuring cotton pads, for example made of cotton with a weight of 100-250 g / m 2 .
  • the invention also relates to a method for strengthening and structuring nonwovens made of staple fibers or filaments such as viscose, polyester, polypropylene, polyamide or lyocell with a weight of 30-300 g / m 2 .
  • the invention also relates to a method for consolidating and structuring wetlaid nonwovens made from natural fibers such as cellulose, or from synthetic fibers such as polyester, or from chemical fibers such as viscose or lyocell, each with only 100% fiber content or alternatively from mixtures of The aforementioned fibers, for all of the aforementioned wet-laid nonwovens with a weight of 30-120 g / m 2 , preferably 45-70 g / m 2 , when used as a wipe, preferably with a weight of 30-100 g / m 2 .
  • fibers 2 are, for example, deposited wet on a belt by an inclined screen former (not shown) and transported to a structuring area 21 via a belt 3.
  • staple fibers can also be deposited and processed on a belt.
  • the fibers can also be arranged as a base or middle layer between two fiber layers, a spunbond, a woven or knitted fabric.
  • the belt 3 below is designed as an air- and water-permeable sieve belt or spunlace belt and is deflected and driven via several rollers 4a-4f.
  • the wet-laid fibers 2 are deposited from a belt (not shown) on an inclined inlet area 20 of the belt 3 and, after conveying, in a flat structuring area 21, as in FIG Fig. 1 shown, or one Structuring area 21 compressed with a level falling in the direction of transport with a counterband 5.
  • the counter belt 5 is also designed as a circulating belt which is deflected and driven by a plurality of rollers 6a-6e.
  • a roller for example roller 6b, can be moved horizontally in order to tension the counterband 5.
  • a small acute angle in the direction of transport is also considered to be a parallel arrangement of the belts 5 and 3, in which the belts form a small open gap of, for example, 0.3 to 2 mm, which is preferably advantageous in the production of cotton pads or wipes. This avoids compression of the fleece, since the end product should be as fluffy as possible.
  • a parallel arrangement of band 3 with counterband 5 is advantageous.
  • the roller 6e can be arranged to be vertically adjustable.
  • the parallel band guide which forms the structuring area 21, does not have the task of compacting the fibers in the conventional sense. In this area, only the water is to be drained off, the fibers are stabilized to form a fleece and structured by the at least one nozzle bar 7 in combination with the pattern-forming openings 5a of the counterband 5.
  • the length of the parallel belt guide ensures a minimum dwell time for water drainage and for chambering the fibers, which at different transport or processing speeds Depending on the fibers to be processed can be varied, for example, in that the rollers 4b, 6a and 6e are designed to be horizontally adjustable.
  • the nonwoven is structured by means of a linear or punctiform arrangement of the water jets in a row, the parallel belt guidance over a minimum length of 0.2 m enables the fibers to be stabilized while at the same time removing water.
  • a further water bar 11 with a suction 12 can be arranged, which at a low pressure of, for example, 15 bar can achieve an additional slight consolidation of the non-consolidated areas without impairing the structuring.
  • This water bar can also be operated at a low pressure of, for example, 15-30 bar in order to solidify the fleece while at the same time maintaining the structuring through the openings 5a.
  • the system can be operated with a fiber weight of 100 - 250 g / m 2 .
  • the fiber weight is preferably 45 - 70 g / m 2, and in wipes 30-100 g / m 2.
  • the counterband 5 after Figures 2 to 2d has a plurality of patterning openings 5a, which give the solidified nonwoven a desired surface structure.
  • the pattern-giving openings 5a can be chosen almost arbitrarily, provided that the strength of the counterband 5 is not impaired.
  • a large number of micro-openings 5b are arranged between the pattern-forming openings 5a and serve not only to improve the water drainage but also to strengthen the fleece.
  • the pattern-forming openings 5a are each shown as a single contiguous recess in the counterband 5, between which the micro-openings are arranged.

  • the fibers 2 are compressed in the area of the pattern-forming openings 5a, as a result of which the nonwoven becomes thinner at these points.
  • Suction boxes 9, 10 are arranged beneath the belt 3, which suction the water from the water bars 7, 8.
  • the band 3 and the counter band 5 are aligned in the area of the water beams 7, 8 parallel or almost parallel to one another over a length of at least 0.2 m, thereby forming the structuring area 21 and, at the same time, locally or selectively compacting the fibers during the water jet consolidation.
  • the micro-openings 5b have the further advantage that the fibers 2 or the solidified nonwoven does not stick to the tape 3 and can therefore be detached more easily, so that there are fewer delays at the transition points between two transport units.
  • the counterband 5 can be made of a bendable plastic with a thickness of 0.3 to 1.0 mm.
  • the counterband 5 is as in Figure 2 shown, can be produced from a bendable metal with a thickness of 0.1-0.4 mm, preferably with a thickness of 0.2-0.3 mm.

  • the dwell time for structuring the fleece is longer.
  • the micro-openings 5b result in a point-by-point consolidation, since the fibers bridge several micro-openings 5b, which results in a step-bed effect.
  • the result is a fleece that is solidified at certain points and has a very high fluffiness that can be used as a cotton pad for the cosmetics sector, as a wipe or so-called flushable wipe.
