A process for the production of a nonwoven fabric. In particular, it relates to the production of a nonwoven fabric having desirable tactile and haptic as well as mechanical properties, as well as to the nonwoven fabric itself. The process requires the selection of specific polylactic acid polymers and corresponding process conditions.

A cartridge includes a tape-shaped nonwoven fabric, a reel on which the nonwoven fabric is wound, and a case that accommodates the reel. A basis weight of the nonwoven fabric is equal to or less than 25 g/m.sup.2.

A fiberball includes: a core region; and a shell region. A fiber density in the core region is higher than a fiber density in the shell region. At least 50% by weight of fibers contained in the fiberball, based on a total weight of the fibers contained in the fiberball, have a length of at least 60 mm.

A nonwoven material formed of bicomponent fibers may be used as a cosmetic cushion to hold cosmetic compositions, such as liquid foundation, in a housing for consumer use with an applicator. The use of bicomponent fibers may allow for the utilization of various natural or synthetic materials for the core and shell which may be adjusted for greatest compatibility with cosmetic compositions. Bicomponent fibers forming nonwoven materials may be a polyethylene terephthalate (PET) core/polyethylene (PE) shell composition. This PET/PE composition may allow for maximum stability and chemical resistance in combination with aggressive chemical ingredients. Cosmetic cushions using these nonwoven materials may feel sensationally pleasing to the consumer and perform with the best quality throughout the lifetime of the product. The cosmetic cushion also may look aesthetically pleasing when filled or saturated with product.

A fiber aggregation contains fiber containing a thermoplastic resin, each of the fiber being mutually joined and aligned.

A water permeability-imparting agent containing an alkylene oxide adduct (A) of a polyvalent active hydrogen compound represented by Formula (1):

R—[O(A.sup.1O).sub.m—(CH.sub.2CH.sub.2O).sub.n—H].sub.1   (1)

wherein R represents a residue, after removal of all active hydrogen, of the polyvalent active hydrogen compound; A.sup.1O represents a C2 to C4 alkyleneoxy group; m represents an average addition mole number of A.sup.1O and is a number of 4 to 50; n represents an average addition mole number of CH.sub.2CH.sub.2O; and 1 represents a valence and is an integer of 3 to 6, and an average addition mole number ratio between A.sup.1O and CH.sub.2CH.sub.2O in Formula (1), n/m, is 0 to 0.5.
