Definitions

  • the invention relates to a fiber laminate which comprises two carrier webs and absorptive fiber material inserted between the two carrier webs and is bonded by hydroentanglement.
  • the invention further relates to a method and an apparatus for producing such a fiber laminate.
  • a method for the production of a composite nonwoven consisting of at least one carrier web, for example a spunbond web, and one layer of wood pulp deposited on such a carrier web for producing a hygiene product, wherein the spunbond web is consolidated in dry condition for preliminary bonding prior to coating with the super-absorbent material, the wood pulp layer is then added and both together are bonded by means of hydroentanglement and then are dried.
  • carrier web for example a spunbond web
  • wood pulp layer is then added and both together are bonded by means of hydroentanglement and then are dried.
  • EP 1 524 350 describes a fiber laminate, in particular an absorbent cleaning cloth, consisting of at least one pre-consolidated spunbond web made of filaments and at least one fiber layer made of hydrophilic fibers, wherein the fiber laminate is hydrodynamically consolidated and wherein embossed deformations are incorporated into the surface of the hydrodynamically consolidated fiber laminate.
  • the two outer layers consisting of pre-consolidated spunbond webs and the inner layer consisting of air-laid pulp are bonded with each other by hydroentanglement.
  • the fiber laminate according to the invention comprises two carrier webs and absorptive fiber material inserted between these two carrier webs and is bonded by hydroentanglement.
  • This fiber laminate When looking at the surface area of this fiber laminate, there are sections with absorptive fiber material between the two carrier webs and sections where the two carrier webs directly touch each other.
  • absorptive fiber material is placed between two carrier webs.
  • the three layers, namely the two carrier webs with the absorptive fiber material placed in between, are consolidated by means of hydroentanglement using a structuring perforated template with the openings in the template being of just such a size that the absorptive fiber material between the two carrier webs is washed away from the sides of the webs of the template toward the openings of the template by the water jet treatment.
  • a corresponding device for production of the fiber laminate is provided with a structuring perforated template having openings with a diameter between 0.5 and 20 mm.
  • these openings are distinctly bigger because they are not designed for draining any liquid but for taking up the fibers of the absorptive fiber material between the two carrier webs which are washed away from the webs of the template.
  • the width of the webs is preferably selected within a range from 1 to 5 mm.
  • the carrier webs either consist of spunbond webs or layers made of staple fibers which are preferably pre-bonded in dry condition, for example by calendering.
  • the absorptive fiber material favorably consists of a pulp layer, such as tissue, or a super-absorbent layer.
  • the areal weight of the carrier webs usually ranges from 3 to 18 g/cm2 and in particular from 6 to 10 g/cm2.
  • the average areal weight of the absorptive fiber material preferably lies between 8 and 100 g/cm2 and in particular between 20 and 50 g/cm2.
  • the areas of absorptive material are preferably distributed over the surface of the fiber laminate in such a way that they provide the fiber laminate with a knobbed structure. It is also conceivable to use such structures of an arbitrary geometry in order to provide the fiber laminate with an attractive optical design as, for example, in the shape of a flower pattern formed by several structures.
  • the structuring template is favorably designed as drum shell or endless shell.
  • water jets 10 meet the fiber laminate, which consists first of a carrier web 1 made of spunbond web at the top, absorptive fiber material 2 underneath and a second carrier web 3 also made of spunbond web at the bottom.
  • absorptive fiber material 2 is included between the top carrier web 1 and the bottom carrier web 3 .
  • top carrier web 1 and bottom carrier web 3 are in direct contact with each other. This structure is explained by the water jets 10 impinging from the top washing away the absorptive fiber material 2 from a web 7 of the template 4 toward the side in the direction of the openings 6 of the template 4 .
  • the impact of the water jets 10 thus literally forces the absorptive fiber material 2 away from the web 7 in the direction of the openings 6 .
  • Located underneath the structuring template 4 is a supporting wire mesh 5 with a supporting drum shell 11 underneath.
  • the supporting wire mesh 5 can be generally designed as a porous boyd or also as a microporous shell.
  • Shown beside the openings 6 of the template 4 is a distinctly smaller capillary opening 8 , which is used for removal of water and for this purpose has a rather small diameter in a range of less than 0.45 mm.
