Definitions
- the invention relates to a method for producing a carrier element for a device for perforating a nonwoven by means of hydrodynamic Vernadling according to claim 1, a device for perforating a nonwoven fabric by hydrodynamic needling according to the preamble of claims 7 and 12 and a method for perforating a nonwoven by means Hydrodynamic needling according to claim 25.
- Previously known devices for perforating a nonwoven by means of hydrodynamic needling have at least a first carrier element with a first carrier surface.
- the first carrier surface has first elevations and first perforations as the drainage opening.
- the nonwoven to be processed can be placed on the carrier surface.
- the fibers arranged on the Rauchoberflä ⁇ che nonwoven are washed down from the ridges, so that perforations are formed in the web.
- there is the disadvantage that in particular heavy nonwovens with a weight per unit area of more than 70 g / m 2 are only poorly perforable.
- Heavy nonwovens are often used as geotextiles. These often consist of a hydrophobic material, in particular staple fibers or endless Filaments made of PP or PET. However, in order to use the heavy nonwovens as geotextiles, some of them are additionally equipped with hydrophilic finishes for better drainage of surface water. According to the present invention, instead of the hydrophilic finish, drainage openings are to be introduced into such heavy nonwovens, wherein these drainage openings are to be introduced by means of hydrodynamic needling. This has the advantage that this is a simpler and less expensive process than the equipment with the hydrophilic finish.
- the object of the present invention is therefore to provide a device and a method for perforating a nonwoven fabric and to provide a method for producing a carrier element for a device for perforating a nonwoven, which makes it possible to produce heavy nonwovens having a basis weight of 70 g / m 2 to perforate.
- the invention has the advantage that the elevations are introduced into the sheet metal element by means of deep drawing. As a result, elevations can be introduced into the sheet-metal element which have a height such that perforations can also be introduced into a heavy fleece by means of these elevations. Furthermore, the coating has the advantage that the carrier element having the coating has a longer shelf life.
- the support elements are usually made of stainless sheet metal. However, this has the disadvantage that the sheet has a relatively high toughness and the increase can only have certain shapes and dimensions. Furthermore, the increase in a stainless sheet can not be introduced by deep drawing. With such a stainless sheet, the height of the ridges may be less than one-half the diameter of the ridges.
- the advantage is that the sheet is first deep-drawn and thus increases of any shape and height can be produced. Durability is obtained by the carrier element through the coating.
- the ridges which are introduced into the sheet metal element may each have a dimension and shape such that a heavy nonwoven having a basis weight of at least 70 to 260 g / m 2 is perforable in the hydrodynamic needling by the ridges, so that in the web Perforations with an opening width of at least 4 mm arise.
- the elevations of the carrier element can have a polygonal, circular, semicircular or oval-shaped cross-sectional shape as base area.
- the perforations may also have a polygonal, circular, semicircular or oval cross-sectional shape in the nonwoven plane.
- the shape of the perforations in the fleece depends on the shape of the elevations in the carrier element.
- the shape of the perforations may additionally z. B. depending on whether the fleece when removing from the support element, e.g. in the transport direction stretches. In this case, oval perforations are formed in the mat, although the elevations of the support element have circular cross-sectional shapes.
- the opening width is the widest width of the respective opening.
- the opening width is the diameter.
- Ovals, ie. preferably elliptical perforations each have a largest and a smallest diameter.
- the opening width is the largest diameter of the oval.
- the smallest width of the oval perforation is the smallest diameter.
- the ridges which are introduced into the sheet metal element may each have a dimension and shape such that a heavy nonwoven having a basis weight of at least 70 to 260 g / m 2 is perforable in the hydrodynamic needling by the ridges, so that in the web Perforations arise whose smallest width has at least 3 mm.
- the sheet metal element may consist of a material having such a toughness that the elevations in the sheet metal element by means of deep drawing can be introduced, wherein the material is preferably a metal.
- the sheet metal element has a toughness, in which the elevations are introduced by deep drawing in the sheet metal element, the elevations can be introduced with a simple and inexpensive process in the support element.
- the sheet metal element may be coated with a material having a higher toughness than the material of the sheet metal element. This has the advantage that the carrier element has a much longer durability.
- the sheet metal element can be coated with a metal, preferably nickel.
- the sheet metal element is preferably not made of nickel.
- Nickel has a too high strength, so that the elevations can not be introduced by deep drawing in the sheet metal element when the sheet metal element consists of nickel.
- the invention advantageously provides that in a device for perforating a nonwoven by means of hydrodynamic needling, a second carrier element is provided which has a second carrier surface with second elevations and second perforations as a drainage opening, wherein on the one hand the elevation of the carrier element have such a distance from one another and on the other hand, the fleece provided with the perforations can be placed on the second carrier element in such a way that the elevations of the second carrier element protrude into the perforations of the fleece arranged on the second carrier element, at least one second jet bar being provided. see and wherein the fleece can be acted upon by means of a liquid emerging from the openings of the second nozzle bar under high pressure.
