Provided is a nonwoven fabric for skin care products. The nonwoven fabric includes: a thermoplastic resin fiber having a single fiber diameter of 50 nm or more and 800 nm or less; and a cellulose fiber. A tensile strength of the cellulose fiber measured in accordance with JIS L 1015:2010 8.7.2 is 1.9 cN/dtex or less, a total content of the thermoplastic resin fiber and the cellulose fiber is 85% by mass or more relative to a total mass of the nonwoven fabric for skin care products, a content ratio by mass of the thermoplastic resin fiber and the cellulose fiber (thermoplastic resin fiber/cellulose fiber) is 0.23 to 1.50, and a density of the nonwoven fabric for skin care products is 0.08 g/cm.sup.3 to 0.16 g/cm.sup.3.

Provided are a space filling material and a space filling structure capable of filling a predetermined space for various purposes, and method for using those. A space filling material (11) includes reinforcing fibers as an expansion material and a resin. The reinforcing fibers form a plurality of intersections and are bonded with the resin at at least one of the intersections. Heating of the space filling material causes an expansion stress in at least a thickness direction (X) such that the space filling material fills a predetermined space (13). For example, the space filling material may contain the resin at a volume ratio of 15 to 95 vol % based on a total volume of the reinforcing fibers and the resin.

A paper machine clothing, in particular a press felt, for a machine for producing or processing a fibrous material web, includes a base structure and at least one layer of nonwoven fibers disposed on the base structure.
