Method for making hydroformed expanded spun bonded nonwoven web

A method for hydroforming a spun bonded nonwoven web includes applying a plurality of pressurized liquid jets onto an original unexpanded spun bonded nonwoven web having an original loft while the web passes over a forming structure. A plurality of spun bonded fibers in the original unexpanded spun bonded nonwoven web are reoriented from a closely packed substantially horizontal orientation to a more loosely packed orientation with greater vertical spacing between the fibers to produce a hydroformed expanded spun bonded nonwoven web having a loft of at least about 1.3 times greater than the original loft of the original unexpanded spun bonded nonwoven web, and an air permeability of at least about 1.2 times greater than an original air permeability of the original unexpanded spun bonded nonwoven web. The hydroformed expanded spun bonded nonwoven web has a surface with a plurality of protuberances in a pattern corresponding to the pattern of apertures in the forming structure.

FABRIC HAVING TOBACCO ENTANGLED WITH STRUCTURAL FIBERS

A smokeless tobacco product includes smokeless tobacco and structural fibers. The structural fibers forming a network in which the smokeless tobacco is entangled. The structural fibers have a composition different from the smokeless tobacco. The tobacco-entangled fabric can have an overall oven volatiles content of at least 10 weight percent. In some embodiments, the structural fibers form a nonwoven network. In some embodiments, fibrous structures of the smokeless tobacco are entangled with the structural fibers.

MELAMINE WIPES AND METHODS OF MANUFACTURE
20200040496 · 2020-02-06 ·

Methods for manufacturing wipes including melamine entangled into a nonwoven, and associated articles of manufacture. Such a method may include providing a melamine sheet (e.g., contiguous, rather than discrete melamine particles), providing first and second nonwoven sheets, and positioning the melamine sheet between the first and second nonwoven sheets. The sandwich structure is hydro-entangled at high pressure to force the melamine material to become entangled into the nonwoven material, to a degree that a portion of the melamine is actually exposed on the exterior face(s) of the wipe, which are generally provided by the nonwoven sheets. Such a wipe exhibits the drapability of a wipe, with the scrubbing benefits (e.g., very effective cleaning of baseboards, crayon off walls, etc.) of melamine, with greater durability than existing melamine cleaning articles, which tend to quickly crumble during use.

Multi-component fibers or filaments that are ribbon shaped are provided having polymer components positioned in a side-by-side fashion. For example, the multi-component fibers may be bicomponent fibers having ribbon shape. The polymer components of the fibers are selected to have differential shrinkage behavior. Nonwovens are also provided that are manufactured from such ribbon shaped multi-component fibers or filaments.

Dispersible moist wipe and method of making

A dispersible moist wipe includes regenerated cellulose fibers in an amount equal to or less than 20 percent by weight and natural cellulose fibers in an amount equal to or greater than 80 percent by weight. At least 50 percent of the natural cellulose fibers are fibrillated. The regenerated cellulose fibers and the natural cellulose fibers are hydroentangled such that the web has a wet CD tensile strength of at least 200 grams per inch. A method of making a dispersible nonwoven sheet includes dispersing natural cellulose fibers and regenerated cellulose fibers in a liquid medium to form a liquid suspension and depositing the liquid suspension over a forming surface to form a nonwoven web. The natural cellulose fibers and regenerated cellulose fibers of the web are hydroentangled using a plurality of hydroentangling jets.
