The present invention relates to a process for making a laminate material (10) which is particularly useful in disposable absorbent articles. In particular the process can be used to provide a laminate of liquid impervious film (12) and a liquid pervious nonwoven substrate (16) with a particulate material (14) between them. The film and the nonwoven substrate are attached to each other by thermal bonding for example by spot welding (18). The process is adapted such that it can be used to produce the laminate as part of a larger process to make absorbent articles.
Procédé de production d'une matière stratifiée (10) qui est particulièrement utile dans des articles absorbants jetables. De manière plus spécifique on peut utiliser le procédé de cette invention pour produire un stratifié de voile (12) imperméable aux liquides et d'un substrat (16) non-tissé perméable aux liquides entre lesquels se situe une matière particulaire (14). Le voile et le substrat non-tissé sont fixés ensemble par liaison thermique, par soudure par points (18) par exemple. Ce procédé est adapté pour être utilisé afin de produire le stratifié dans le cadre d'un procédé plus vaste de production d'articles absorbants.
