Definitions

  • the present invention relates to a method for solidifying a nonwoven fabric by means of water jet treatment.
  • the solidification of the carded fabric presented is achieved by an interweaving and turbulence of the fibers.
  • the submitted fibers are detected by the water jets, set in motion and three-dimensional entwined by a swirling movement.
  • cotton is generally considered, see e.g. the article "Aquajet spunlace process - technology for cotton fibers” by Alfred Watzl, Fa. Fleissner.
  • Aquajet spunlace process - technology for cotton fibers by Alfred Watzl, Fa. Fleissner.
  • the low wet modulus of the cotton fibers and the fact that the fiber does not have a round, smooth fiber cross section.
  • modulus of elasticity fibers with a high modulus of elasticity (hereinafter referred to as "modulus of elasticity") are suitable. These are essentially non-cellulosic fibers.
  • the present invention has as its object to provide a method for hydroentanglement of fiber webs, which is feasible with a lower energy consumption.
  • This object is achieved by a method for solidifying a nonwoven fabric by means of water jet treatment, which is characterized in that the nonwoven fabric contains flat fibers in the form of collapsed viscose hollow fibers with a ratio of width B to thickness D of B: D ⁇ 10: 1.
  • the present invention relates to a hydroentangled nonwoven fabric containing flat fibers in the form of collapsed viscose hollow fibers with a ratio of width B to thickness D of B: D ⁇ 10: 1.
  • the flat fibers contained in the nonwoven fabric preferably have a ratio B: D of 10: 1 to 30: 1, particularly preferably of 20: 1.
  • the flat fibers may preferably have a titer of 0.9 to 5 dtex, particularly preferably 1.3 to 1.9 dtex.
  • Flat fibers and their production are known.
  • Flat fibers have a substantially flat or elongated cross-section, in contrast to the usually substantially circular cross-section of fibers.
  • cellulosic flat fibers can be produced by spinning a cellulose or a cellulose derivative containing dope through slit-shaped spinnerets.
  • flat fibers may alternatively be in the form of collapsed Hollow fibers are produced.
  • a gas for example nitrogen, or a blowing agent, for example sodium carbonate, is mixed into the spinning viscose.
  • cellulosic flat fibers are for example from the GB 945,306A , of the US 3,156,605 A , of the US 3,318,990 , of the GB 1,063,217 A known.
  • Such fibers have been proposed, in part for use in papermaking, as described in part in the documents just mentioned.
  • the WO 2006/134132 describes the use of Viskoseflachmaschinen in a fiber composite with the purpose to improve the solubility of the fiber composite in water.
  • the flat fibers used have according to WO 2006/134132 preferably a krenellATORATOR (crenellated) surface, so are produced in contrast to collapsed hollow fibers by means of spinning through a slot nozzle.
  • the ribbed surface of such flat fibers reduces fiber-fiber adhesion and thus strength.
  • the achievable thickness in conventional flat fibers is limited by the nozzle geometry. When spinning with nozzles with an opening of 25 ⁇ m height results in general, a fiber thickness of about 4-6 ⁇ m. In order to consistently produce a fiber thickness of about 2-3 ⁇ m as with collapsed hollow fibers, a nozzle orifice of about 12.5 ⁇ m in height would be necessary, which is not economically viable in either nozzle making or viscose fiber production by conventional techniques.
  • the viscose flat fibers used according to the invention are collapsed hollow fibers which, as mentioned above, can be produced by introducing gas or a blowing agent (in particular sodium carbonate) into the spinning viscose.
  • the fiber can be completely collapsed or still slightly open.
  • the water retention capacity of the fiber should preferably be 200% or less (measured according to DIN 53814).
  • the fiber cross section of the fibers should be predominantly flat and preferably not branched.
  • the proportion of the flat fibers in the nonwoven fabric is preferably 5% to 100%, in particular 20% or more, particularly preferably 50% or more.
  • the nonwoven fabric can thus consist entirely of the flat fibers or else contain a mixture of the flat fibers with other fibers.
  • Suitable mixing partners are all cellulosic and non-cellulosic fiber materials which are suitable for hydroentanglement. It is clear to those skilled in the art that the effect of the present invention (i.e., increasing the strength of the web or saving energy) is the more pronounced the higher the content of the flat fibers in the web is.
  • the invention also relates to a hydroentangled nonwoven fabric comprising flat fibers in the form of collapsed viscose hollow fibers with a ratio of width B to thickness D of B: D ⁇ 10: 1.
  • a hydroentangled nonwoven fabric comprising flat fibers in the form of collapsed viscose hollow fibers with a ratio of width B to thickness D of B: D ⁇ 10: 1.
  • the fibers were presented as carded web and solidified on both sides in two passages.
  • Nonwoven fabrics with two basis weights and with two solidification stages (lighter - higher solidification) were produced from each fiber.
  • Basis weights 50g / m 2 or 80g / m 2
  • Solidification stages (solidification pressure indicated in each case as the sum of all pressures of all nozzle beams in both passages) Basis weight 50g / m 2 - slight consolidation: 65 bar Basis weight 50g / m 2 - higher consolidation: 95bar Basis weight 80g / m 2 - light consolidation: 95bar Basis weight 80g / m 2 - higher consolidation: 145bar
  • the higher solidification pressure is thus about 50% above the low solidification pressure.
  • the maximum elongation at break (with the same basis weight and with the same consolidation) is significantly lower for nonwovens made from flat fibers than for nonwoven fabric made from standard viscose fibers. This is probably due to the higher proportion of fiber-fiber bonds.
  • Nonwovens with flat fibers show, at the same experimental settings, a significantly higher MD / CD ratio than nonwovens made from standard viscose fibers.
  • the MD / CD ratio increases by reorienting the fibers in the solidification process.
  • the significantly higher MD / CD ratio of the nonwovens made of flat fibers compared to the nonwoven fabrics of standard viscose fibers at the same pressures shows the significantly higher flexibility of the flat fiber, which substantially facilitates the solidification process.
  • Table 3 Nonwoven fabric made of viscose flat fiber (according to the invention) grammage solidification stage Dry Wet Maximum tensile force [N / 5cm] Maximum tensile force [N / 5cm] MD + CD MD + CD 50 g / m 2 Light 74.1 50.1 50 g / m 2 High 72.3 54.5 80 g / m 2 Light 122.9 84.7 80 g / m 2 High 119.6 82.8
  • Table 4 Nonwoven fabric made of standard viscose fiber (comparison) grammage solidification stage Dry Wet Maximum tensile force [N / 5cm] Maximum tensile force [N / 5cm] MD + CD MD + CD 50 g / m 2 Light 54.5 37.8 50 g / m 2 High 81.3 46.0 80 g / m 2 Light 62.1 27.4 80 g / m 2 High 98.8 59.8
  • the strength of a nonwoven fabric normally correlates with the basis weight for the same consolidation.
  • the nonwoven reached only about 75% of its solidification potential in this solidification stage.
  • the example of the 80 g / m 2 nonwovens clearly shows the advantages of the use according to the invention of flat fibers in water-jet solidification.
