Abstract

Un article absorbant comprend une couche d'arrêt de l'humidité, un revêtement situé côté corps, lié à cette dernière, et un élément absorbant placé entre la couche d'arrêt de l'humidité et le revêtement situé côté corps. Des bourrelets élastiques, servant de couches physiques tridimensionnelles d'arrêt du mouvement des liquides, sont placés sur les bords de l'article. Les bourrelets élastiques comprennent une couche d'arrêt interne, et une couverture élastique placée sur cette dernière, et liée à l'un des bords de l'article. Dans certains modes de réalisation, la couverture élastique est constituée d'un matériau hydrophobe, n'adhérant pas à la couche d'arrêt interne et/ou constituée de fils élastiques ayant un degré de puissance variable. Un procédé de fabrication de cet article absorbant comprend les étapes constituant à fournir une bande de support continue, présentant des bords opposés, et à disposer une bande absorbante continue sur la bande de support continue, entre les bords latéraux. Des fils continus d'un matériau formant une couche d'arrêt interne sont placés sur la bande de support continue, un des fils étant placé entre la bande absorbante et chacun des bords latéraux. La bande de support continue, la bande absorbante, et les fils du matériau formant couche d'arrêt interne constituent une structure composite en cours de fabrication qui est coupée dans le sens transversal pour former plusieurs structures composites individuelles. Chacune de ces structures individuelles comprend une structure absorbante et une paire de structures formant couches d'arrêt internes, placées sur une feuille de support. Le procédé consiste également à disposer les structures composites individuelles sur une bande formant couche d'arrêt continue de l'humidité, et à prévoir une paire de couches de couverture continues. Ces dernières sont élastiques sur au moins une partie de leur longueur et sont positionnées sur les structures formant couches d'arrêt internes. Les couches formant couvertures continues sont liées à la couche d'arrêt de l'humidité et la bande d'arrêt de l'humidité et les couches de couverture sont coupées entre les structures composites individuelles.
