The application relates to a method and apparatus for manufacturing a natural fiber based staple fibers. The application further relates to the staple fibers, staple fiber based raw wool and products comprising such. A method comprises providing a cellulose suspension (101, 310, 510) including water, refined cellulose fibrils and at least one rheology modifier, directing the cellulose suspension through a nozzle (102, 320, 520) onto a surface (300, 400, 500), drying the cellulose suspension onto the surface (103, 300, 400, 500) for forming a fiber (350, 550), and cutting the cellulose suspension on the surface for forming staple fibers (105).

Disclosed are materials comprising a fiber material and an agent having at least one having improved tensile strength, in particular wet tensile strength, vis--vis fiber materials known from the art. While these fiber materials may be of use in various fields, in particular household products, hygiene products and the like, these fiber materials are of particular use in wound treatment. Also disclosed is a method for producing these materials.

Provided herein is a new fire barrier material composed of flame retardant (FR) cellulosic fiber(s) and one or more of an antimicrobial (AM) cellulosic fiber and an untreated cellulosic fiber(s). The fire barrier material may be a fabric woven or knitted from the yarn containing the FR cellulosic fiber(s) and the one or more of AM cellulosic fibers and untreated cellulosic fibers. When AM cellulosic fibers are combined with FR treated cellulosic fibers, the fire barrier material has the dual features of flame retardancy and antimicrobial properties. The fire barrier material may also be a nonwoven, and in preferred embodiments optionally includes a binder fiber. The FR cellulosic fiber contains FR chemical(s) or FR compound(s) that have a melting point or decomposition temperature at 400 C. (752 F.) or below. The FR performance of the new nonwoven provided herein is comparable to the conventional FR nonwoven (FR cellulosic fiber/binder fiber), but has advantages in cost effectiveness, as well as antimicrobial properties.

A fiber assembly including fibrils including a fibril which is a part of a fiber extending in a direction of thickness of the fiber assembly and including a network structure formed with a binding portion resulting at least any from binding between fibrils and binding between a fibril and a fiber in at least any end portion in the direction of thickness of the fiber assembly and a liquid absorbent sheet-like article including the same as well as a fiber assembly which is excellent in diffusion of a liquid particularly at a surface and absorption thereof in the inside and includes fibrils and a liquid absorbent sheet-like article including the same as well as a method of manufacturing the fiber assembly can be provided.

In one aspect, an example article for treating a textile with an antimicrobial agent includes: (a) a nonwoven multicomponent sheet, wherein the nonwoven multicomponent sheet comprises at least two materials; and (b) an antimicrobial agent comprising at least one of a metal ion or quaternary ammonium compound having antimicrobial activity, wherein an efficacious amount of at least one of the metal ion or quaternary ammonium compound transfers to the textile during a laundry cycle.

A package has a container formed with a dispensing opening and a supply of nonwoven disinfecting wipes in the container. The wipes are made of fibers containing lignin and impregnated with a disinfectant solution having at least two liquid components. A lignin content of the nonwoven wipes is between 0.02 g/m.sup.2 and 1 g/m.sup.2 and/or the disinfectant solution contains a dye. Thus if at least a part of one of the wipes is overexposed to air, it will change color as oxidized lignin and/or dye collects in it.

There is provided a nonwoven fabric for skin care products excellent in adhesion and wiping properties, and soft touch to the skin. The nonwoven fabric includes synthetic fibers and cellulose fibers. When a maximum length of a cross section of the synthetic fibers is denoted by A and a maximum width thereof is denoted by B, flatness expressed by the formula (1) is 1.0 to 1.5:

flatness=A/B(1) the synthetic fibers have recesses, a depth of which is 1.0% or more and 10.0% or less relative to a single fiber diameter of the synthetic fibers, a single fiber diameter of the synthetic fibers is 1 ?m or more and 20 ?m or less, a content of the synthetic fibers is 30 to 70% by mass relative to the entire nonwoven fabric for skin care products, a content of the cellulose fibers is 70 to 30% by mass relative to the entire nonwoven fabric for skin care products, and an average single fiber diameter of all fibers constituting the nonwoven fabric for skin care products is 5 ?m or more and 20 ?m or less.
