An improved cloth-like base web is disclosed. In particular, the base web of the present invention has a cloth-like look and feel and has improved absorbency. The base web is made by first hydroneedling a web containing pulp and/or staple fibers. A bonding material is then applied to at least one side of the web and the web is creped on at least one side. By combining a hydroneedling operation with a creping operation, a base web is produced that is strong, stretchable, very soft and absorbent.
L'invention concerne une bande de support améliorée de type tissu. En particulier, la bande de support de la présente invention a l'aspect et la texture du tissu, tout en présentant des qualités supérieures d'absorption. La bande de support se fabrique tout d'abord par hydro-aiguilletage d'une bande renfermant des fibres de pâte ou des fibres discontinues. On applique ensuite un matériau de liaison sur une face au moins de la bande, et l'on crêpe ladite bande sur au moins une face. Un procédé combinant une opération d'hydro-aiguilletage et une opération de crêpage permet d'obtenir une bande de support résistante et extensible, particulièrement douce et absorbante.
