This invention relates to polyvinyl alcohol fibers, methods of making polyvinyl alcohol fibers and products manufactured from polyvinyl alcohol fibers. The invention relates particularly but not exclusively to products comprising extruded polyvinyl alcohol fibers, methods of making extruded polyvinyl alcohol fibers and products incorporating such fibers.

Described is a pouched product for oral use that includes a liquid permeable cover material and a portion sized amount of a filling material has a water insoluble particulate material, the filling material being enclosed by the liquid permeable cover material. The particles of the water insoluble particulate material have an average particle size within the range of from 0.3 mm to 3.0 mm, a particle density in the range of from 0.8 g/cm.sup.3 to 1.7 g/cm.sup.3 and a pre-use moisture content of from 1% by weight of the filling material to 35% by weight of the filling material.

The present invention provides a laminated nonwoven fabric achieving both handling properties during manufacturing and use and adherence to a skin surface at a high level particularly when used for a face mask. The laminated nonwoven fabric includes a nonwoven fabric layer (A) and a nonwoven fabric layer (B). The nonwoven fabric layer (A) is formed from a fiber A having a single fiber diameter of 50 nm or more and 800 nm or less, and the nonwoven fabric layer (B) is formed from a fiber B having a single fiber diameter of 3 m or more and 30 m or less. The nonwoven fabric layer (B) includes 15 to 40% by mass of a fiber B1 to all of the fibers constituting the nonwoven fabric layer (B), the fiber having tensile strength of 2.0 cN/dtex or less as measured based on JIS L 1015: 2010 8.7.2. The nonwoven fabric layer (B) Includes a fiber B2 having tensile strength exceeding 2.0 cN/dtex as measured based on JIS L 1015: 2010 8.7.2. The nonwoven fabric layer (A) is disposed as an outermost layer of at least one surface.

A non-flip mattress with top side and bottom side and depending edges; wherein the bottom side is covered with a flame-resistant, highly needled, double-sided-calendered, needlepunch nonwoven fabric that passes 16 CFR 1633. The nonwoven fabric is a double-calendered, 80/20 polyester/flame-resistant rayon blend needled with a minimum of 190 punches per cm.sup.2 and with increased tensile strength.

Filter media suitable for various applications (e.g., hydraulic) and related components, systems, and methods associated therewith are described. The filter media may include a fiber web having a mixture of glass fibers and fibers that are fibrillated. The fibrillated fibers, for example, may be formed of lyocell.

Disclosed are a lyocell fiber, a nonwoven fibrous aggregate containing the lyocell fiber, and a mask pack sheet containing the nonwoven fibrous aggregate. The lyocell fiber contains a monofilament having a cross-section of a flat yarn or a flat yarn having a curvature. Such lyocell fiber exhibits physical properties that could not be provided by existing lyocell fibers having a circular cross-section, and thus can afford excellent properties such as excellent bendability for industrial material application, good feel and soft gloss property for clothes or interior applications, and transparency, skin adhesion, absorption, and maintenance of a solvent such as moisture, and a smooth surface feel for a mask pack nonwoven fibrous aggregate application.

There is disclosed a nonwoven fabric. The nonwoven fabric may comprise short fibers of plant-based material having a length of about between 2 mm and 5 mm, and cellulose filaments being present at a proportion of up to 10 wt-% of the nonwoven fabric, such that the cellulose filaments bind the short fibers in the nonwoven fabric. Long fibers are optionally added to the nonwoven fabric.
