  • Publication number: 20010037529
    Abstract: The present invention provides a fiber product-treating agent which can impart an excellent wrinkle-resistant effect and an excellent durable press effect to the fiber product capable of being heated and being hardly effected with not only during wearing but also after washing. That is, the present invention provides the treating agent for imparting the durable press configuration on a fiber product by a heating treatment with e.g. an iron, which comprises a specific amount of (i) two or more compounds forming mutually a crosslinked structure by heating and/or (ii) a compound forming a self-crosslinked structure by heating, and water, wherein the content of a nonvolatile matter is 0.01 to 30%.

  • Patent number: 6306961
    Abstract: A thermoplastic resin composition comprises a thermoplastic resin (A) and graft copolymer particles (B) having a hollow rubber portion and graft chain, in which a volumetric proportion of hollow part in the hollow rubber portion of the graft copolymer particles is 1 to 70% by volume. The thermoplastic resin composition contains the thermoplastic resin and the graft copolymer particles in a weight ratio (A)/(B) of 2/98 to 100/1. The hollow part in the graft copolymer particle functions to further improve impact resistance.

  • Patent number: 6069216
    Abstract: A cationic group-containing copolymer is provided which possesses excellent thixotropy and exhibits high adsorbability to the skin, hair, etc. and, when incorporated as a thickener in cosmetic articles, manifests a very satisfactory tactile sensation. The cationic group-containing copolymer is characterized in that the viscosity at 25.degree. C. of the aqueous solution prepared by incorporating the copolymer in deionized water at a concentration of 0.5 wt. % is in the range of 0.3-20 Pa.multidot.sec. at a shear rate of 1 sec.sup.-1 and in the range of 0.01-5 Pa.multidot.sec. at a shear rate of 10 sec.sup.-1 and the viscosity at a shear rate of 1 sec.sup.-1 is higher than the viscosity at a shear rate of 10 sec.sup.-1.

  • Patent number: 5747016
    Abstract: An organopolysiloxane which generates intramolecular or intermolecular cross-linking based on dipole-dipole interaction, hydrogen bonding or ion bonding, and which is not ruptured or plastically deformed at an extension ratio no more than 15% at a temperature of 20.degree. C. under relative humidity of 65%; and a method of setting hair using the same. Hair which is set by the method retains the given shape over time, and the organoplysiloxane imparts a soft touch to the hair. In addition, the shape given by the setting treatment can be easily restored to the original shape by ordinary shampooing.
