Abstract: A skin-covering sheet for impregnation with a cosmetic preparation according to the present invention includes a non-woven fabric in which a splittable conjugate fiber containing at least two components as viewed in fiber cross-section, namely a polyethylene component and another polymer component, and a hydrophilic fiber are blended, and hydroentangled. The conjugate fiber is partially split and includes a polyethylene ultrafine fiber having a fineness of 0.6 dtex or less. A face mask according to the present invention includes the skin-covering sheet for impregnation with a cosmetic preparation impregnated with 500 to 2000 mass % of a liquid containing a cosmetic preparation. It is therefore possible to obtain a skin-covering sheet for impregnation with a cosmetic preparation and a face mask that have good impregnating ability of a cosmetic liquid into the sheet layer, cause very little irritation to the skin, and are soft in texture.

Abstract: A POM/POM thermoadhesive conjugate fiber is produced by providing two kinds of POM-based polymers A and B which satisfy 30<MIA wherein MIA is a before-spinning melt index (g/10 min) of the POM-based polymer A (conditions: 190° C., load: 21.18N (2.16 kg)), and TB>TA+10 wherein TA and TB are before-spinning fusion peak temperatures of the POM-based polymers A and B respectively, compositely spinning a first component containing the POM-based polymer A and a second component containing the POM-based polymer B such that the first component is exposed with an exposed length of not less than 20% relative to a peripheral length of the fiber, subjecting the spun fiber to a drawing treatment, and subjecting the drawn fiber to an annealing treatment at a temperature of from 60° C. to 110° C.
