  • Publication number: 20200093188
    Abstract: A water repellency-imparted fiber article (10) of the present invention includes: a fiber article (1) having a skin-facing surface (1a) and a non-skin-facing surface (1b); and a water repellency-imparting agent attached to the fiber article (1). The fiber article (1) contains a water-absorbent fiber and has water absorbency in terms of a water absorption time of 30 seconds or less as measured in accordance with the dropping method of JIS L-1907. The water repellency-imparted fiber article (10) has a non-skin-side water-repellent region (2) on the non-skin-facing surface (1b) of the fiber article (1), the non-skin-side water-repellent region (2) including a portion to which the water repellency-imparting agent is attached.

  • Patent number: 9243128
    Abstract: A composite material of the invention is a mixture of cellulose microfibers having a carboxyl group content of 0.1 to 3 mmol/g and a moldable polymeric material selected from the group consisting of a biomass-derived polymer and a petroleum-derived polymer. The biomass-derived polymer is preferably polylactic acid or pulp. The cellulose microfibers are preferably present in an amount of 0.01% to 60% by mass. Another composite material of the invention is a mixture of cellulose composite microfibers and a moldable resin, the cellulose composite microfibers being obtained by adsorbing a surfactant onto cellulose microfibers having a carboxyl group content of 0.1 to 3 mmol/g.

  • Patent number: 8298520
    Abstract: Disclosed is a deodorant particle having a BET specific surface area of 10 m2/g or more that are obtained by copolymerizing a monomer system including a crosslinkable vinyl monomer and a vinyl monomer having a heteroaromatic ring. The deodorant particles may contain a metal ion. Also disclosed is a process of producing the deodorant particles including the step of copolymerizing a monomer system containing a crosslinkable vinyl monomer and a vinyl monomer having a heteroaromatic ring by oil-in-water emulsion polymerization or precipitation polymerization using an organic solvent whose solubility parameter is different from that of the monomers by an absolute difference of 0 to 2.0. The process can further include the step of bringing the particles obtained by the polymerization into contact with a solvent having a metal salt dissolved therein to support a metal ion on the particle.
