  • Patent number: 4333979
    Abstract: Lightweight, pattern bonded, generally continuous filament web having physical, aesthetic, and functional attributes particularly desirable for liner material for disposable absorbent products such as diapers, sanitary napkins, and the like. In accordance with a preferred embodiment of the invention, a continuous filament polypropylene web is formed and pattern bonded by heat and pressure producing a high frequency of high density bond areas. This bonded web is then subjected to hot embossing in a gross pattern producing permanent web deformation and increasing the web effective thickness. In use the nonwoven web of the invention provides a very soft, flexible web having a pleasing appearance and yet retaining strength properties making it very effective at low basis weights for applications such as liners for disposable diapers, sanitary napkins, and the like.
