Title
(EN) IMPROVED ABSORBENT COMPOSITE MAT
(FR) TAPIS COMPOSITE ABSORBANT AMELIORE
Abstract
(EN)
An improved absorbent composite mat (18) comprising at least one layer of a nonwoven natural-fiber laminar web (10) attached to a nonwoven synthetic fibrous laminar web (12) is disclosed. At least one surface of the composite mat is impregnated with a polymeric emulsion (14). A preferred embodiment of the invention utilizes raw staple cotton as the natural fiber. This is fed to a garnet to form a web (10), which is then attached to a thinner synthetic web (12) by a needling process (30). Finally, it is sprayed with a polymeric emulsion (14) containing polyvinyl chloride to afford buoyancy to the mat.
(FR)
On décrit un tapis composite absorbant amélioré (18) comprenant au moins une couche en une étoffe (10) non tissée en fibres naturelles stratifiées, fixée à une étoffe (12) non tissée en fibres synthétiques stratifiées. Au moins une surface du tapis composite est imprégnée avec une émulsion polymère (14). Une forme d'exécution préférée fait appel à des fibres de coton brut, pour les fibres naturelles. On traite ces fibres sur une garnetteuse et on forme une étoffe (10) qui est alors fixée à une étoffe synthétique plus mince (12), par un procédé d'aiguilletage (30). Finalement, on pulvérise sur l'ensemble une émulsion (14) d'un polymère contenant du chlorure de polyvinyle, afin d'améliorer la flottabilité du tapis.
