    摘要： Methods for manufacturing wipes including melamine entangled into a nonwoven, and associated articles of manufacture. Such a method may include providing a melamine sheet (e.g., contiguous, rather than discrete melamine particles), providing first and second nonwoven sheets, and positioning the melamine sheet between the first and second nonwoven sheets. The sandwich structure is hydro-entangled at high pressure to force the melamine material to become entangled into the nonwoven material, to a degree that a portion of the melamine is actually exposed on the exterior face(s) of the wipe, which are generally provided by the nonwoven sheets. Such a wipe exhibits the drapability of a wipe, with the scrubbing benefits (e.g., very effective cleaning of baseboards, crayon off walls, etc.) of melamine, with greater durability than existing melamine cleaning articles, which tend to quickly crumble during use.

    摘要： The invention relates to the use of a microfilament fabric comprising at least one layer A which comprises a fiber component in the form of microfilaments, which are laid down to produce a nonwoven and are bonded by jets of fluid, and have an average titer of less than 0.15 dtex, in the form of melt-spun microfilaments which are laid down to produce a nonwoven, and/or in the form of composite filaments which are split and bonded by fluid-jet bonding at least to some extent to produce elementary filaments having an average titer of less than 0.15 dtex, as a technical packaging material. The invention also relates to a microfilament composite fabric which comprises a microfilament fabric of this type, and also relates to a method for the production thereof.

    摘要： A spunbond nonwoven from thermoplastic filaments is made by spinning the filaments from at least one spinner, cooling and stretching the spun filaments, depositing the cooled and stretched filaments on a surface to form a nonwoven fleece web, and moving the fleece web in a travel direction. A liquid medium is introduced into the moving fleece web and it is then mechanically needled. The mechanically needled web is then subject to a hydraulic or hydrodynamic final consolidation by hydroentanglement to a basis weight of more than 80 g/m2 from a top side as well as from a lower side of the nonwoven fleece web by high-pressure water-jet bars above and below the nonwoven fleece web. O of the bars is upstream of the other bar and has a hpi density that is smaller than that of the other bar and that is equal to at most 40.
