In the liquid-retaining sheet, the transparency shown below is adjusted to not more than 0.27. Transparency=Whiteness (%) of a sheet impregnated with 700% by mass of water relative to the sheet mass/Basis weight (g/m2) The transparent fiber may contain a cellulose-series fiber substantially free from a carboxyl group (in particular, a regenerated cellulose fiber such as a solvent-spinning cellulose-series fiber). The proportion of the solvent-spinning cellulose-series fiber may be not less than 30% by mass in the transparent fiber. The liquid-retaining sheet may be a skin care sheet (in particular, a facial mask) that is impregnated with a liquid component containing a cosmetic preparation.

  • Patent number: 8021996
    Abstract: The present invention provides a nonwoven web prepared from multicomponent fibers which are partially split. The partially split multicomponent fibers have at least one component of the multicomponent fiber separated from the remaining components of the multicomponent fiber along a first section of the longitudinal length of the multicomponent fibers. Along a second section of the longitudinal length of the multicomponent fibers the components of the multicomponent fibers remain together as a unitary fiber structure. In addition, part of the second section of the multicomponent fibers is bonded to part of a second section of an adjacent multicomponent fiber.

  • Patent number: 7998889
    Abstract: An hydroentangled integrated composite nonwoven material, includes a mixture of randomized continuous filaments, and synthetic staple fibers, where there are no thermal bonding points between the continuous filaments. The nonwoven material exhibits a cumulative pore volume, measured by PVD in n-hexadecane, in the pore radius range 5-150 ?m, where at least 70% of the cumulative pore volume is in the pores with a pore radius above 45 ?m. The nonwoven material also exhibits a cumulative pore volume, which when the synthetic staple fibers are chosen from the group of polyethylene, polypropylene, polyester, polyamide, and polylactide staple fibers is at least 9 mm3/mg, and when the synthetic staple fibers are lyocell staple fibers is at least 6 mm3/mg.

  • Publication number: 20110151738
    Abstract: Dimensionally stable nonwoven fibrous webs include a multiplicity of continuous fibers formed from one or more thermoplastic polyesters and polypropylene in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 10% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. A spunbond process may be used to produce substantially continuous fibers that exhibit molecular orientation. A meltblown process may be used to produce discontinuous fibers that do not exhibit molecular orientation. In some embodiments, the fibers comprise a viscosity modifier and/or an anionic surfactant. The webs may be used as articles for filtration, sound absorption, thermal insulation, surface cleaning, cellular growth support, drug delivery, personal hygiene, medical apparel, or wound dressing.

  • Patent number: RE42765
    Abstract: A plant serves as a mean for production of a fibre web of synthetic fibres, such as plastic fibres and absorbent fibres, such as viscose and cellulose fibres. The plant includes a forming head preliminary to lay a homogeneously and smoothly distributed fibre layer on a net shaped wire. Furthermore the plant includes a hydro-entangling section with liquid nozzles with powerful liquid jets to treat the in the forming head formed fibre layer, which consists of both synthetic—and absorbent fibres. The plant also includes an oven subsequently to thermal bond the synthetic fibres with cross bonds in the affected areas. Finally the dried web is winded up in a roller. By the help of the plant according to the invention, by higher production speed than known previously a fibre web can be produced, which is far cheaper, and which has a better and more homogeneous structure than similar conventional fibre webs.
