摘要:
A perforated non-woven fabric (10) and a manufacturing method thereof. The perforated non-woven fabric (10) consists of at least one fiber layer. The at least one fiber layer has a plurality of through-holes (101). A total area of the plurality of the through-holes (101) accounts for 10-80% of a total area of the perforated non-woven fabric (10). An opening of the plurality of the through-holes (101) is level with a surface of the perforated non-woven fabric (10). The density of the plurality of the through-holes (101) in the perforated non-woven fabric (10) is 3-100 through-holes/cm2. A fiber density at the edge of each through-hole (101) is similar to or the same as a fiber density at other areas of the perforated non-woven fabric (10). Fibers surround the through-hole (101) and adhere to each other by only a surface layer thereof. The non-woven fabric (10) neither forms, at the edge area of the through-holes (101), a stiff end by being cut, nor melts and forms a fiber-dense area or membranous area. The fibers surround the through-hole (101) and only melt and adhere to each other at the surfaces thereof, such that the softness of the non-woven fabric (10) is not compromised by perforation and a granular feeling due to perforation is reduced.Linvention concerne un tissu non-tissé perforé (10) et son procédé de fabrication. Le tissu non-tissé perforé (10) est constitué dau moins une couche de fibres. La ou les couches de fibres ont une pluralité de trous traversants (101). Une surface totale de la pluralité des trous traversants (101) représente 10 à 80 % dune surface totale du tissu non-tissé perforé (10). Une ouverture de la pluralité des trous traversants (101) se situe au niveau dune surface du tissu non-tissé perforé (10). La densité de la pluralité des trous traversants (101) dans le tissu non-tissé perforé (10) est de 3 à 100 trous traversants/cm2. Une densité de fibres au niveau du bord de chaque trou traversant (101) est similaire ou identique à une densité
