Title (EN) PERFORATED NON-WOVEN FABRIC AND MANUFACTURING METHOD THEREOF
(FR) TISSU NON-TISSÉ PERFORÉ ET SON PROCÉDÉ DE FABRICATION
(ZH) 一种开孔无纺布及其制作方法
Abstract:
(EN) 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.
(FR) L'invention concerne un tissu non-tissé perforé (10) et son procédé de fabrication. Le tissu non-tissé perforé (10) est constitué d'au 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 % d'une surface totale du tissu non-tissé perforé (10). Une ouverture de la pluralité des trous traversants (101) se situe au niveau d'une 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 de fibres au niveau d'autres zones du tissu non-tissé perforé (10). Des fibres entourent le trou traversant (101) et adhèrent les unes aux autres seulement par une couche superficielle correspondante. Le tissu non-tissé (10) ne forme pas, au niveau de la zone de bord des trous traversants (101), d'extrémité rigide en étant coupé, pas plus qu'il ne fond et forme une zone fibreuse dense ou une zone membraneuse. Les fibres entourent le trou traversant (101) et fondent et adhèrent seulement les unes aux autres au niveau de leurs surfaces, de telle sorte que la souplesse du tissu non-tissé (10) n'est pas compromise par perforation et une sensation granulaire due à la perforation est réduite.
(ZH) 一种开孔无纺布(10)及其制作方法,该开孔无纺布(10)由至少一纤维层组成,其上具有多个通孔(101),多个通孔(101)的总面积占该开孔无纺布(10)总面积的10~80%,多个通孔(101)的开口与开孔无纺布(10)的表面平齐,且多个通孔(101)在该开孔无纺布(10)上的密度为3个/cm 2~100个/cm 2,每个通孔(101)的边缘的纤维密度与开孔无纺布(10)的其它区域的纤维密度相近或相同,且纤维环绕在通孔(101)周围仅纤维表层相互粘合。该无纺布(10)在通孔(101)的边缘区域不会被切断形成僵硬断头,或熔融形成纤维密集的区域或膜化区域,仅是纤维围绕通孔(101)的周围,纤维表面熔融而相互粘连从而不会因为开孔而破坏了无纺布(10)的柔软性,减少因开孔所带来的颗粒感。
