  • Patent number: 7967951
    Abstract: An object of the present invention is to provide an embossed crepe paper which can clearly be formed into fine embossed shapes, and is excellent in the fluffy feel and therefore excellent in such as absorbency for fats. As a means of achieving this object, the method for manufacturing an embossed crepe paper, according to the present invention, is a method for manufacturing an embossed crepe paper comprising a step of embossing a raw crepe paper, wherein: a raw paper having a basis weight of 6 to 28 g/m2 is used as the raw crepe paper; and the embossing step includes the steps of: (a) supplying the raw crepe paper with water in an amount of 0.1 to 100 weight % based on the basis weight to thereby put the raw crepe paper in a wet condition; (b) embossing the wet-conditioned raw crepe paper; and (c) drying the embossed wet-conditioned raw crepe paper.

  • Publication number: 20080075760
    Abstract: The moisturized nonwoven fabric of the invention contains 1% or more of a water-soluble component to a weight of a pre-moisturized nonwoven fabric and an increase ratio of an equilibrium moisture regain (equilibrium water content) is 0.5% or more as compared with an equilibrium moisture regain of the moisturized nonwoven fabric after the water-soluble component is removed. Therefore, this moisturized nonwoven fabric is excellent in use feel such as skin touch and wiping property and functionalities such as water absorption property and water retention property. Further, this moisturized nonwoven fabric is excellent in functionalities such as moisturizing liquid transferring capability and skin moisturizing effect.
