  • Hydrophilizing agent and hydrophilized fiber treated therewith
    Patent number: 7857861
    Abstract: The hydrophilizing agent contains (a) a cationized compound of a (poly) amine, (b) an ester, (c) a dialkyl sulfosuccinate salt, (d) an alkylphosphate salt, (e) at least one glycine derivative selected from the group consisting of trialkyl glycine derivatives and (alkylamide alkyl) dialkyl glycine derivatives, and (f) a polyoxyalkylene-modified silicone; wherein the ratio of the component (a) ranges from 10 to 40 wt. %, the ratio of the component (b) ranges from 10 to 40 wt. %, the ratio of the component (c) ranges from 1 to 40 wt. %, the ratio of the component (d) ranges from 10 to 60 wt. %, the ratio of the component (e) ranges from 10 to 40 wt. %, and the ratio of the component (f) ranges from 1 to 20 wt. % of the hydrophilizing agent.

  • Water-permeability imparting agent and fiber having the agent applied thereto
    Publication number: 20060182965
    Abstract: A water-permeable agent comprising at least one specific quaternary ammonium salt and at least one specific phosphate salt being formulated in specific ratios, and water-permeable fiber and fiber products produced by applying the water-permeable agent to fiber and fiber products by 0.1 to 2.0 weight percent. The present invention provides a water-permeable agent, which decreases wetback of disposable diapers and sanitary napkins, having been decreased by modifying their construction in conventional measures, with improved permanent water permeability, and decreased time-dependent deterioration of permanent water permeability, and is applicable to fibers processed in high-speed nonwoven production processes; and fiber and fiber products applied therewith.
