Non-woven fabric for liquid-permeable sheet of absorbent article, and absorbent article which includes said non-woven fabric as liquid-permeable sheet

This non-woven fabric comprises the following configuration. In this non-woven fabric for a liquid-permeable sheet of an absorbent article, said non-woven fabric comprising a thickness direction, a planar direction, a first face, and a second face: the non-woven fabric includes thermoplastic resin fibers, and cellulosic fibers, at least a portion whereof configures a plurality of fiber masses; the non-woven fabric further comprises a plurality of spaces which are adjacent to first regions of each of the plurality of fiber masses, said first regions facing the first face; and each of the plurality of fiber masses is not bonded to the thermoplastic resin fibers.

Composition of matter in a pre-refiner blend zone

A composition is contained a blend zone prior to refining containing non-fibrillated virgin cellulose fibers, waste/recycle cellulose fibers or both; cellulose ester fibers, water, and one or more additives comprising fillers, internal sizing agents, biocides, process anti-foaming agents, colorants, optical modifiers, or a combination thereof. An in-line mixer can be used for adding the additives, and the consistency of the composition is lowered relative to a feed of material from a hydropulper.

Natural nonwoven materials

There is described a nonwoven material comprising a multilayered stack, the multilayered stack comprising discrete interconnected layers, each of the layers, which may be the same or different, comprising a composite fibre of from about 80 to 100% w/w leaf or stem fibre and from about 1 to 20% w/w of a polymer, wherein the polymer is fusible at a temperature of about 180° C. or less. There is also described a novel method of enzyme degumming leaf and/or stem fibres.

Composition of matter in stock preparation zone of wet laid process

A composition obtained by combining virgin cellulose fibers, cellulose ester (CE) staple fibers having a denier per filament (DPF) of less than 3, and water, and water. The CE staple fibers can also have a short cut length of less than 6 mm and can be crimped. The compositions, when co-refined, are useful to make wet laid products such as paper, cardboard, and filters that have improved water drainage, air permeability, tensile strength, bulk, burst strength, or stiffness, or a combination of these properties.

Fibrous structures exhibiting improved whiteness index values
