A process for making a spunmelt nonwoven web including the steps of providing a mixture of recycled polypropylene, extruding the recycled polypropylene mixture to form a molten recycled polypropylene mixture, filtering the molten recycled polypropylene mixture through a filter to form recycled polypropylene filtrate, dosing the recycled polypropylene filtrate into the spunmelt production line by an amount of 80% to 100% by weight, passing the recycled polypropylene filtrate through at least one spinneret of the spunmelt production line to form filaments at a spinning speed of greater than 1200 meters per minute, cooling and drawing the filaments, and depositing the filaments on a moving belt to form at least one layer of the spunmelt nonwoven web made up of 80% by 100% by weight of recycled polypropylene fibers.

Fibrous structures, for example sanitary tissue products, such as toilet tissue, and more particularly fibrous structures containing a movable surface and methods for making same and methods for making same are provided.

Fibrous structures comprising a movable surface

Thick and absorbent and/or flexible toilet tissue and methods for making same are provided.

Bonded formed laminates, and methods for making bonded formed laminates, are made from multiple layers of formed substrates comprising at least one nonwoven formed substrate which are bonded together at the distal ends or bases of protrusions formed in the substrates. The bonded formed laminate provides a very soft and lofty structure that is sustainable under compression.

Bonded laminate including a formed nonwoven substrate

A material web is disclosed. The material web includes a fiber layer having a first side and an opposing second side. The fiber layer has a plurality of fibers, each of which having an intimate admixture of a thermoplastic polymer, and a wax and/or oil, wherein at least some of the wax and/or oil is exposed at an outer surface of the fibers. A surface energy treatment is disposed on the first side and/or the second side of the fiber layer.

Fibers of polymer-wax compositions

Rolls of toilet tissue containing a movable surface and methods for making same are provided.

Disposable article that include fibers formed from compositions comprising thermoplastic polymers and waxes are disclosed, where the wax is dispersed throughout the thermoplastic polymer.

Disposable article or nonwoven that includes a first fiber layer comprising a plurality of fibers, each of which comprising an intimate admixture of a thermoplastic polymer, and a wax and/or oil, wherein at least some of the wax and/or oil is exposed at an outer surface of the fibers and wherein a surface energy treatment is disposed on at least some of the plurality of fibers; and a second fiber layer that is adjacent the first fiber layer and that comprises a plurality of cellulosic fibers.

A melt spinnable fiber is provided that comprises a first component comprising a thermoplastic polymer, and a second component comprising thermoplastic starch where the second component is not encompassed by another component or components or if encompassed by another component or components then the second component encompasses a hollow core. A particular use of such a fiber is for removal of the second component in the presence of a solvent in order to produce fibers with desired properties. An agent may be present in the second component for controlling the rate of removal of the second component thereby allowing for physical manipulation of the fiber prior to complete removal of the component. The invention is also directed to nonwoven webs and disposable articles comprising the fibers.

Process of producing a melt-spinnable fiber using thermoplastic polymer and destructured starch

The present invention is directed to articles comprising nanofibers. The nanofibers, having a diameter of less than 1 micron, may comprise a significant number of the fibers in one layer of the web contained by the article. Preferably, the nanofibers are produced in a melt film fibrillation process. The articles include diapers, training pants, adult incontinence pads, catamenials products such as feminine care pads and pantiliners, tampons, personal cleansing articles, personal care articles, and personal care wipes including baby wipes, facial wipes, and feminine wipes.

Methods of producing fibers, nonwovens and articles containing nanofibers from broad molecular weight distribution polymers

The present invention is directed to articles comprising nanofibers. Preferred articles include diapers, training pants, adult incontinence pads, catamenials products such as feminine care pads and pantiliners, tampons, personal cleansing articles, personal care articles, and personal care wipes including baby wipes, facial wipes, body wipes, and feminine wipes. The nanofiber webs can be used as a barrier, wipe, absorbent material, and other uses. The nanofibers, having a diameter of less than 1 micron, must comprise a significant number of the fibers in at least one nanofiber layer of the nonwoven web. The nonwoven web may have a hydrohead to basis weight ratio of greater than about 10 mbar/gsm. The nanofibers may be produced from a melt film fibrillation process.
