A process for increasing the wet tensile strength properties of a porous plug wrap paper for use in smoking articles is disclosed. The wet strength properties of the paper are increased by incorporating into the paper an alkyl ketene dimer and by applying a size containing polyvinyl alcohol to a surface of the paper. The wet strength properties of the paper can be increased without using cross-linking agents. Porous plug wrap papers made in accordance with the present invention can have a wet tensile strength retention of at least 20%.

Process for increasing the wet strength of porous plug wraps for use in smoking articles

A method and apparatus of manufacturing a web which is striped with add-on material, comprising: a first arrangement which establishes a sheet of base web from a first slurry and moves the established sheet along a first path; a second arrangement for preparing a second slurry; a moving orifice applicator operative so as to repetitively discharge the second slurry upon the moving sheet of base web, the moving orifice applicator comprising: a chamber box arranged to establish a reservoir of the second slurry across the first path; an endless belt having an orifice, the endless belt received through the chamber box; a drive arrangement operative upon the endless belt to continuously move the orifice along an endless path and repetitively through the chamber box, the orifice when communicated with the reservoir being operative to discharge the second slurry from the reservoir through the orifice; a flow distribution system for introducing the second slurry into the chamber box at spaced-apart feed locations along the chamber box; a flow monitoring system for reading fluid pressure at spaced-apart locations along the chamber box; and a controller arranged to identify which of the feed ports is operatively adjacent a monitored location of highest pressure variation, the controller selectively adjusting output of the flow distribution system at the identified feed location counteractively to the highest pressure variation, the controller adjusting output of a remainder of the feed locations counteractively to the output adjustment at the identified feed location.

Method and apparatus for applying a material to a web

Disclosed is a lightweight nonwoven laminate particularly useful as a component of personal care articles, for example as a barrier cuff material for disposable diapers. Components of the laminate include at least one fine fiber layer having a basis weight in the range of from about 1.5 gsm to 26 gsm and at least one continuous filament layer having a basis weight in the range of from about 10 gsm to 30 gsm. The fine fiber component comprises at least a ratio of 5% and the layers are intermittently bonded for a total basis weight up to about 55 gsm. Desirable softness, breathability and barrier properties are obtained.

Disposable garment with improved containments means

A multilayer nonwoven fabric is disclosed which comprises at least two layers of nonwoven web. Each nonwoven web comprises a plurality of monofilaments of a thermoplastic material. In at least one of the webs the monofilaments have a bilobal cross-section. Preferably, the fabric includes two layers of nonwoven web with the monofilaments of the first web having the bilobal cross-section and the monofilaments of the second web having a trilobal or branched cross-section.

Multilayer nonwoven fabric

Nonwoven webs are disclosed which comprise monofilaments or fibers of a thermoplastic material. Basically, the improvement comprises the use of monofilaments or fibers which have a bilobal shaped cross-section. Nonwoven webs made according to this invention are particularly suited to be used for liners for disposable diapers as well as wraps for catamenial devices. Methods are also disclosed for producing such nonwoven webs.
