Claims (24)
wobei die Bahn eine Vielzahl an beabstandeten Spalten definiert, wobei eine jede ein oberes (404) und ein unteres (402) Ende besitzt, und jeder der Spalten sich von einer Oberfläche der Bahn um mindestens 50 Prozent durch die Dicke der Bahn hindurch erstreckt;
wobei die Dichte des Abschnitts der Bahn, der das untere Ende des Spalts (402) begrenzt, grösser ist als die Dichte des Abschnitts der Bahn, der das obere Ende des Spalts (404) begrenzt, und die Fasern von einer Flüssigkeit benetzt werden können, welcher die Fa serbahn ausgesetzt werden kann.1. fibrous web ( 400 ) having a length, a width and a thickness, at least about 50 percent of the fibers being oriented in a direction which is generally perpendicular to the length and width of the web;
the web defining a plurality of spaced gaps, each having an upper ( 404 ) and a lower ( 402 ) end, and each of the gaps extending from a surface of the web by at least 50 percent through the thickness of the web;
wherein the density of the portion of the web that defines the lower end of the gap ( 402 ) is greater than the density of the portion of the web that defines the upper end of the gap ( 404 ) and the fibers can be wetted by a liquid, which the fiber train can be exposed to.
die Fasern mit einem oberflächenaktiven Mittel behan delt und einem Coronafeld ausgesetzt wurden;
die Bahn eine halsgestreckte, schmelzgeblasene Vlies bahn umfasst; und
die zahlreichen beabstandeten Spalten im wesentlichen parallel zueinander sind.10. The fibrous web ( 400 ) of claim 3, wherein:
the fibers have been treated with a surfactant and exposed to a corona field;
the web comprises a neck-stretched, melt-blown nonwoven web; and
the numerous spaced columns are substantially parallel to each other.
die Fasern im wesentlichen in eine Richtung ausgerich tet sind, die sich im allgemeinen vom oberen Abschnitt einer jeden Mulde (102) zu ihrem unteren Abschnitt (108) erstreckt;
die Fasern von einer Flüssigkeit benetzt werden kön nen, der das in eine Z-Richtung führende Flüssigkeits transportmittel ausgesetzt werden kann;
die Dichte der Bahn am Boden einer jeden Mulde (108) grösser ist als die Dichte der Bahn im restlichen Teil der Mulde; und
die Fasern im oberen Abschnitt einer jeden Mulde (102) im wesentlichen von den Fasern an den oberen Abschnit ten benachbarter Mulden unterbrochen sind.11. Liquid transport means ( 500 ) leading in a Z direction, which defines a plurality of generally V-shaped troughs, each comprising a lower section ( 108 ) and a bifurcated upper section ( 102 ), and which is composed of a fibrous web is where:
the fibers are oriented substantially in a direction generally extending from the upper portion of each trough ( 102 ) to its lower portion ( 108 );
the fibers can be wetted by a liquid which can be exposed to the liquid transporting in a Z direction;
the density of the web at the bottom of each well ( 108 ) is greater than the density of the web in the rest of the well; and
the fibers in the upper portion of each well ( 102 ) are substantially interrupted by the fibers at the upper portions of adjacent wells.
die Fasern mit einem oberflächenaktiven Mittel behan delt und einem Coronafeld ausgesetzt wurden;
die Faserbahn eine halsgestreckte, schmelzgeblasene Vliesbahn umfasst; und
die zahlreichen Mulden im wesentlichen parallel zuein ander sind.19. A Z-direction liquid transport agent ( 500 ) according to claim 11, wherein:
the fibers have been treated with a surfactant and exposed to a corona field;
the fibrous web comprises a neck-stretched, meltblown nonwoven web; and
the numerous troughs are essentially parallel to each other.
