ALMOHADILLA ABSORBENTE DE CAPAS MULTIPLES MEJORADA,PARA USARSE EN ARTICULOS ABSORVENTES DESECHABLES,TALES COMO PANALES Y PROCEDIMIENTO PARA PRODUCIR LA MISMA

摘要

A multi-layer absorbent pad (20) for use in disposable absorbent articles, such as diapers (10) and the like, to absorb body fluids is characterized by having superior fluid transfer from a top uncompressed receiving layer (21) to a bottom compressed layer (22) and wicking and spreading action of the body fluids within the bottom layer (22) to provide a drier top surface to the absorbent pad. The top layer (21) is formed of fiberized cellulosic fibers including a cationic debonding agent provided therein prior to fiberization for obtaining more complete fiberization of the fibers and greater height and loft to the layer while producing resistance to normally-occurring hydrogen bonds between the fibers in the layer to resist compression of the layer and maintain the height and loft of the absorbent pad. The bottom layer (22) is formed of fiberized cellulosic fibers without a cationic debonding agent therein for allowing compression of the layer by effecting the normally-occurring hydrogen bonds between the fibers in the compressed layer (22) to provide a more densified layer for improved fluid wicking and spreading action.
