  • Publication number: 20150173975
    Abstract: The present invention relates to a nonwoven comprising: a first fiber layer comprising a first core/sheath composite fiber having three-dimensional crimp, which is composed of a sheath component comprising linear low density polyethylene, and a core component comprising thermoplastic resin having a high melting point, and the center of gravity of the core component being offset from the center of gravity of the fiber; a second fiber layer comprising a second core/sheath composite fiber having three-dimensional crimp, which is composed of a sheath component comprising high density polyethylene, a core component comprising thermoplastic resin having a high melting point, the center of gravity of the core component being offset from the center of gravity of the fiber; wherein at least a portion of the first and the second core/sheath composite fibers is thermal bonded via the sheath components of the first and the second core/sheath composite fibers

  • Publication number: 20080069845
    Abstract: A skin application sheet for being impregnated with a cosmetic preparation is provided which is suitable for a face mask and so on, and causes less irritation to skin, and has good application properties. A splittable conjugate fiber web containing at least 50% by mass of splittable conjugate fibers is placed on one surface or both surfaces of a hydrophilic nonwoven containing at least 50% by mass of hydrophilic fibers and hydroentanglement treatment is conducted to split the splittable conjugate fibers into ultrafine fibers with a fineness of 0.5 dtex and to form a ultrafine fiber layer containing at least 10% by mass of the ultrafine fibers and to integrate the hydrophilic nonwoven and the ultrafine fiber layer so that a sheet is obtained. This sheet is impregnated with the cosmetic preparation and used in such a manner that the ultrafine fiber layer is a skin contact surface.
