    摘要： The invention relates to a highly functional spunbonded fabric made from fibres based on non-fusible polymers, which contain one or more functional additives. The fibres are interwoven and interlocked, are of different lengths having aspect ratios above 1.000 and form a firm fleece composite. Said fibres have a mean diameter of 0.1 to 500 micrometres and diameter variations within a fibre and/or among each other of at least 30%. In addition to the non-fusible polymers, the fibres contain, based on the total weight thereof, more than 40 wt % of functional additives in solid and/or liquid form, wherein the functional additives are finely distributed in the fibres. The spunbonded fabric is produced from a spinning solution that contains the non-fusible polymer dissolved in a direct solvent, and at least one functional additive. The spinning solution is pressed out of a spinneret, and the resulting polymer strands are drawn in the longitudinal direction to form filaments or fibres, stabilised and laid down to form a fleece fabric. The spunbonded fabrics can be used, for example, to produce clothing, technical textiles or as filters.

    摘要： A nonwoven fabric useful as a component in a personal hygiene product and a nonwoven personal hygiene component, which is substantially free or free of non-ribbon shaped (e.g., round-shaped) spunbond fibers and includes a meltblown layer between and in direct contact with ribbon-shaped spunbond layers. The meltblown layer has a basis weight of at least about 0.008 gsm and not greater than about 5 gsm, and the nonwoven fabric or component has a basis weight of at least about 8 gsm and not greater than about 40 gsm, a pore size of less than or equal to about 27 microns when measured at 10% of cumulative filter flow. The nonwoven fabric also can have a low surface tension liquid strike through flow of less than 0.9 ml per second, a ratio of low surface tension liquid strike through flow to air permeability of greater than or equal to about 0.016, or both. Personal hygiene articles can incorporate the nonwoven fabric or component.
