Further, in this embodiment, the fiber length and the fiber weight of the pulp fibers are the “average fiber length” and the fiber weight (also referred to as the “fiber roughness”) per unit length, respectively. From the evaluation results shown in FIG. 2 , evaluations are made as follows:
  • the rate of recovery after loaded of every specimen in the working examples 1 to 7 exceeds 7%, and it is thus verified that the specimens in the working examples 1 to 7 have higher performance of recovery after loaded, compared with the specimens of the comparative examples 1 and 2 in which the rate of recovery after loaded is below 7%. Therefore, when, for example, a cosmetic puff impregnated with skin lotion is used for patting, a sufficient amount of release of skin lotion can be provided. Further, due to the higher performance of releasing skin lotion, such a cosmetic puff is economical without wasting skin lotion
  • the rate of one-time moisture release of every specimen in the working examples 1 to 7 exceeds 75%, and it is thus verified that the specimens in the working examples 1 to 7 have higher performance of one-time moisture release (at one time or in one step), compared with the specimens of the comparative examples 1 and 2 in which the rate of one-time moisture release is below 75%. Therefore, when, for example, a cosmetic puff impregnated with skin lotion is used for patting, a sufficient amount of release of skin lotion can be provided even by lightly patting the skin. In other words, it is not necessary to pat the skin with a strong force which may put a strain on the skin.
  • the rate of (first to second) moisture release of every specimen exceeds 85%, and the rate of (first to third) moisture release of every specimen exceeds 90%. It is thus verified that the specimens in the working examples 1 to 7 have higher performance of fraction moisture release (in several steps), compared with the specimens of the comparative examples 1 and 2 in which the rate of (first to second) moisture release is below 85% and the rate of (first to third) moisture release is below 90%. Therefore, when, for example, a cosmetic puff impregnated with skin lotion is used for patting several times (in several steps), a sufficient amount of release of skin lotion can be continuously provided. Application of skin lotion to the skin by patting in several steps is effective for increasing moisture in the skin.
  • a cosmetic puff having enhanced usability can be provided by designing it to release an appropriate amount of skin lotion according to the force with which a user pats the skin with the cosmetic puff impregnated with skin lotion.
  • each of the air-laid non-woven fabric sheets corresponding to the specimens of the working examples 1 to 7 contains pulp fibers with a fiber weight per unit length of 0.20 mg/m or more.
  • a pulp fiber has an average pore size (void diameter) of 100 ⁇ m or more and has a strong skeleton structure, so that the rate of recovery after loaded in the wet state, the rate of one-time moisture release and the rate of fraction moisture release can be increased.

  • such a sheet is effective for gradually discharging the skin lotion retained in space between the fibers, to the surface layer.
  • each of the air-laid non-woven fabric sheets corresponding to the specimens of the working examples 2 to 6 contains 10 to 50% of polyethylene terephthalate fibers by weight.
  • the rate of recovery after loaded in the wet state, the rate of one-time moisture release and the rate of fraction moisture release can be further increased, so that the effect of gradually discharging the skin lotion retained in space between the fibers, to the surface layer can be further enhanced.
  • each of the air-laid non-woven fabric sheets corresponding to the specimens of the working examples 1 to 7 contains rayon fibers in areas corresponding to the surface layers 120 , so that the cosmetic puff provide a smooth texture in use. Either one of the two surface layers 120 may be formed by the rayon fibers, as necessary.
  • the mixture ratio of a binder contained in the air-laid non-woven fabric sheet is preferably set to 5 to 15% by weight. If the mixture ratio of the binder is decreased to below 5% by weight, disadvantageously, the rate of recovery after loaded in the wet state is decreased, and the amount of first moisture release is increased. Further, if the mixture ratio of the binder exceeds 15% by weight, disadvantageously, the material is hardened and rendered unsuitable for a cosmetic puff.
  • the content of polyethylene terephthalate fibers in the air-laid non-woven fabric sheet is preferably set to 10 to 50% by weight.
  • the polyethylene terephthalate fibers are hydrophobic, and if the content of polyethylene terephthalate fibers exceeds 50% by weight, disadvantageously, most of the skin lotion absorbed therein is immediately released by first patting, and an increase in the amount of polyethylene terephthalate fibers leads to cost increase.

Further, a plurality of the moisturizer application regions 221 shown in FIG. 3 are arranged to extend in the vertical direction, having the application width d 1 of 1.0 mm and the pitches d 3 of 2.0 mm.
  • the specimen of the working example 1 is used without application of a moisturizer and as a basis of evaluation, i.e. “blank” of the other specimens.

Further, a plurality of the moisturizer application regions 221 shown in FIG. 3 are arranged to extend in the vertical direction, having the application width d 1 of 2.0 mm and the pitches d 3 of 1.0 mm.
  • the thickness of each dry specimen (which corresponds to the sheet thickness h 2 in FIG. 4 ) is measured by using a portable thickness gage (CR-10A of Daiei Kagaku Seiki Mfg. Co., Ltd.).
  • a value B (gf ⁇ cm 2 /cm) of the flexural property is obtained by using a flexural property measuring equipment (KES-FB2 ALTO-A of Kato Tech Co., Ltd.).
  • FIG. 6 shows results of evaluation of each specimen in the working examples 11 to 16 and the comparative examples 11 to 14 in this embodiment on criteria D, E. From the evaluation results shown in FIG. 6 , evaluations are made as follows:
  • the dry thickness of every specimen of the working examples 11 to 16 exceeds 1.2 mm, and it is thus verified that the specimens in the working examples 11 to 16 are kept bulky, compared with the specimens of the comparative examples 12 to 14 in which the dry thickness is far below the initial thickness (1.322 mm) of the comparative example 11. Therefore, the cosmetic puff can be improved in appearance (or provide a quality appearance).
  • the value B (gf ⁇ cm 2 /cm) of the flexural property of every specimen of the working examples 11 to 16 and the comparative examples 12 to 14 is far below the value B (0.2300 gf ⁇ cm 2 /cm) of the comparative example 11. It is thus verified that improvement in texture is realized by application of a moisturizer.
  • the specimens of the comparative examples 12 to 14 each have relatively small pitches, compared with the specimens of the working examples 11 to 16. Therefore, the pitches between adjacent moisturizer application regions are kept unchanged only shortly after application of the moisturizer, but the moisturizer may spread with the passage of time and reduce the pitches finally to almost zero (almost in the state of overall application). As a result, the dry thickness may be reduced. Therefore, if the initial pitches between adjacent moisturizer application regions can be kept unchanged even during use of the product by the user, the pitches and the application width of the moisturizer are not limited to the settings defined in the working examples 11 to 16, but can be appropriately set as necessary.
