  • Patent number: 10493718
    Abstract: A liquid-absorbing multi-layered sheet with a liquid-absorbing central layer and a first and a second outer layer of fibers, tissue or film provided at each their side of the central layer is provided. The central layer is airlaid and includes cellulosic fibers, superabsorbents and heat-adhesive binder fibers. The sheet is peculiar in that the percentage of heat-adhesive binder fibers in the central layer is between 1% and 7% of the total weight of fibers in the central layer. In production, a continuous web with the three layers is conveyed through a heating zone for heating the web, wherein the heating temperature and the heating time are adapted to at least a partial melting of the heat-adhesive binder fibers in the central layer for binding the fibers in the central layer and for binding the outer layers to the central layer.

  • Publication number: 20100090363
    Abstract: There is described a method and an apparatus for making a multilayered web product (1), including at least one fibre layer (6) which is formed by airforming combined with at least one additional layer in the form of a plastic film (13, 21). The fibre layer (6) is formed and fixed, preferably by heat fixing, and the plastic film (13, 21) is extruded directly upon or in immediate association to the previously formed and fixed fibre layer and is joined with the fibre layer by a compacting action in a compacting unit (9, 17). By the compacting, the hot plastic film will be joined to and pressed into the fibre layer for producing an integrated continuous product without need of separate heat supply.
