Definitions

  • the invention relates to an elastic nonwoven fabric and a method for producing an elastic nonwoven fabric.
  • Nonwovens are used in many areas. They are used in medical devices, personal care products, sports and leisure apparel, footwear, bedding and bedding.
  • the invention is therefore based on the object of specifying a nonwoven fabric and a method with which sufficiently elastic textile fabric can be produced inexpensively.
  • a nonwoven fabric comprises a sheet-like layer of thermoplastic filaments, wherein the layer is elastic and can be enlarged in at least one direction by at least 30% of its initial extent.
  • a layer of a nonwoven fabric whose width is increased by at least 30% of its initial value, provides sufficient elasticity for a variety of applications. Furthermore, it has been recognized that the manufacture of a nonwoven fabric of thermoplastic filaments allows to dispense with the addition of relatively expensive filaments such as spandex filaments.
  • the nonwoven fabric according to the invention can be built up uniformly, namely exclusively from thermoplastic filaments, which are orientable in such a way on account of a special treatment that the layer can be enlarged in at least one direction by at least 30% of its initial extent.
  • Such a uniformly constructed nonwoven fabric can be disposed of in an easy way, since it consists of uniform materials. Due to the uniformity of the filaments used storage costs are minimized, so that the production of the nonwoven fabric is inexpensive to carry out. Consequently, the object mentioned above is achieved.
  • the layer could have a basis weight of 40 to 150 g / m 2 .
  • a nonwoven fabric with this basis weight is particularly suitable for use as a textile fabric, since it surprisingly has sufficient stability despite its low basis weight.
  • the sheet could have microfilaments with a fineness of 0.1 to 0.15 dtex. Microfilaments of this fineness allow the production of a nonwoven fabric with very fine pores, which makes it very absorbent and therefore can be used as a functional underwear.
  • the microfilaments are formed by splitting filaments, which have a fineness of 2 to 2.4 dtex before splitting.
  • bicomponent filaments having a pie structure comprising 30% polyamide and 70% polyester may be used here. Bicomponent filaments of this type are particularly easy to split by high-pressure water jets, resulting in finer filaments.
  • the planar position could be wrinkle-free or wave-free.
  • This embodiment makes a post-processing of the elastic nonwoven fabric, which is initially present as a semi-finished, particularly simple. Methods are already known from the prior art, which give elasticity to a nonwoven fabric. However, these processes are so-called dry processes. The dry processes have the disadvantage that the semi-finished products produced by these processes have wrinkles or wrinkles. The formation of these wrinkles and wrinkles is called "tie-dyeing effect".
  • a nonwoven fabric comprising a sheet of thermoplastic filaments can be configured so elastically that the layer can be reversibly enlarged in at least one direction by at least 30% of its initial extent. Furthermore, it has been recognized that this method produces a semi-finished product with a flat layer, which is wrinkle-free or wave-free. In concrete terms, it has been recognized that this method can overcome the creasing and wrinkling known from the prior art in dry processes. In addition, this method is inexpensive because it is feasible in existing plants such as a high temperature jig for dyeing textiles.
  • the web By reducing the speeds to zero and / or reversing the direction of travel of the web, its width could be reduced.
  • the web By carrying out this process step, the web is surprisingly imparted with an elasticity orthogonal to the direction of the tensile load.
  • the water could be heated to 50 ° C. This concrete process step causes the wetting and impregnation of the web with liquid is improved.
  • This concrete process step supports the process of width reduction of the web, namely allows a better sliding of the filaments together, since the friction between them is reduced.
  • the method could be performed such that the temperature is heated to a certain value and the web is moved at a first speed at a first tensile load first in one direction and then in an opposite direction.
  • the process in a first direction and then in an opposite direction is to be understood as the unwinding of the web from a first roll while being wound onto a second roll and unwinding of the web from the second under winding onto the first roll.
  • the width of the web is slightly reduced.
  • the heating of the water to a second temperature could follow this process step, the web optionally being moved in one direction and then in an opposite direction at the same speed and the same tensile load or with an altered tensile load and / or with a changed speed.
  • the web optionally being moved in one direction and then in an opposite direction at the same speed and the same tensile load or with an altered tensile load and / or with a changed speed.
  • the water could finally be heated to a final temperature and the web can be traversed at a speed which is significantly lower than the speed of the first method steps.
  • the tensile load maintains the same value as was observed in the preceding method steps. Due to the significant reduction in the speed of the web and the significant increase in the water temperature is achieved in a surprising manner, a very significant reduction in the width.
  • the web After reaching the maximum temperature of 130 ° C, the web can be traversed at 80 m / min at a tensile load of 60 or 100 daN and thereby dyed become.
  • the elastification is carried out at the same time with a dyeing step.
  • the water could be heated to 130 ° C and the web be traversed at 20 m / min at a tensile load of 60 or 100 daN.
  • This concrete process step finally achieves the surprising effect of a very strong width reduction.
  • the web could be dried on a tenter at 140 ° C while maintaining a longitudinal tension and wound up.
  • This concrete process step allows the production of a semi-finished product with particularly high elasticity and smooth surface.
  • Fig. 1 shows a schematic view of the basic structure of the Hochtemperaturjiggers, which was used to carry out the examples described below.
  • a container 1 contains a volume of water 2 through which a web 3 can be moved.
  • the web 3 is wound on a first roller 4 and is passed through further rollers 5, 6 and 7 through the volume of water 2.
  • the web 3 is wound on a second roller 8.
  • the traversing speed of the web 3 is reduced to zero and the direction is reversed.
  • the web 3 is then unwound again from the second roller 8, moved through the water volume 2 and wound up again on the first roller 4.
  • the unwinding and winding of web of nonwoven raw material may be carried out at various speeds, temperatures and tensile loads, as described in the introduction to the specification.

  • the water was cooled to 90 ° C and unwound the web at a tensile load of 100 daN and a speed of 50 m / min from the second roll and wound on the first.
  • the water was cooled to 70 ° C and unwound the web at a tensile load of 100 daN and a speed of 50 m / min from the first roll and wound on the second.
  • the web After heating the water to 110 ° C, the web was also subjected to a complete unwinding and rewinding, the web was traversed at a tensile load of 100 daN at 50 m / min.
  • Example 1 The process steps of Example 1 were modified to ensure even greater width reduction and better web guidance.
  • the web was dried on a tenter at 140 ° C while maintaining a corresponding longitudinal tension and wound up.
  • Example 1 The web used in Example 1 had a starting width of 195.5 cm. After wet treatment by the method described in Example 1 Process steps, the web had a width of 135 cm, After subsequent drying in the tenter, the web had a width of 140 cm, which corresponds to a width reduction of 28.39%.
  • Example 2 The web treated in Example 2 had an initial width of 195.5 cm. After wet treatment by the process steps described in Example 2, this web had a width of 150 cm. After subsequent drying in the tenter, the web had a width of 150 cm, which corresponds to a width reduction of 23.27%.

  • HTJ high-temperature jigger
  • the return behavior can be improved by further treatment methods. These include heat setting, polyurethane coagulation, softener sizing and sizing. Depending on the methods used, the extensibility may be slightly reduced. This is due to the fact that the friction of the filaments is increased against each other.

  • the nonwovens may additionally be subjected to a softener finish (WM).
  • WM softener finish
  • 10 to 80 g / l plasticizer can be used in a bath through which the nonwoven fabric is passed.
  • Table 2 used 60 g / l of Finistrol KSE (trade name). This is a self-crosslinking, modified polysiloxane.
  • This plasticizer was added to a bath downstream of the high temperature jigger.
  • a plasticizer may be added to the bath of the high-temperature jigger or a bath connected downstream of it.
  • Sengen is understood to mean the flaming off of the fiber ends protruding from a textile fabric through an open gas flame.
  • the material becomes due to this process slightly fused to the surface, so that the crossing points of the filaments connect with each other. This results in a higher stability and a better return behavior back to the starting position.
  • This process step is preferably carried out after the treatment in Hochtemperaturigigger.
  • EVO nonwovens of the type "Evolon”. All nonwovens mentioned in the examples have microfilaments which have a fineness of 0.1 to 0.15 dtex and are formed by splitting bicomponent filaments.
  • the bicomponent filaments had a pie structure and contained 30% polyamide and 70% polyester.
