  • Nonwoven material comprising a certain proportion of recycled fibres originating from nonwoven and/or textile waste
    Patent number: 6037282
    Abstract: Nonwoven material produced by hydroentangling a fiber web, comprising recycled fibers with a fiber length of between 5 and 60 mm and a fineness of between 0.1 and 20 dtex, which are constituted by fibers which are mechanically shredded or torn from nonwoven waste, textile waste or the like. The fibers are mixed with each other and possibly with new fibers in a wet-formed, foam-formed, air-laid or dry-laid fiber web which is hydroentangled with sufficient energy for forming a compact absorbent material.

  • Spunlace material with high bulk and high absorption capacity and a method for producing such a material
    Patent number: 6017833
    Abstract: Nonwoven material produced by hydro-entanglement of a wet- or foam-formed fibre web, which material contains at least 5%, by weight of the total fibre weight, of pulp fibres of chemical-thermomechanical type. These fibres have been mixed with other fibres, such as chemical pulp fibres, vegetable fibres, synthetic fibres or regenerated cellulosic fibres in a wet- or foam-formed fibre web which has been entangled with sufficient energy to produce a dense, absorbent material.
