PROBLEM TO BE SOLVED: To provide a light transmissive composition having excellent light transmissivity.SOLUTION: A light transmissive composition 2 comprises a light transmissive matrix 3 in which nano hollow silica particles 4 are dispersed. Each of the nano hollow silica particles 4 has its primary particle diameter of 300 nm or less, its wall thickness of 30 nm or less, and its voidage of 40% or more, and they are aggregated in the matrix 3 and have their secondary aggregated particle diameters of 1500 nm or less.
Abstract:
PROBLEM TO BE SOLVED: To install a pad member to a frame member in such a way that abnormal noise generation can be avoided as much as possible.SOLUTION: In a vehicle seat, the pad member 6P is arranged on the frame member 6F and an elastic fiber body 10 is brought into contact with the frame member 6F. In addition, the elastic fiber body 10 is provided with projections 12 which project to the frame member 6F side and recesses 14 which contact the pad member 6P side more closely than the projections 12, and is configured to be contactable in a dotted or line pattern to the frame member 6F by the projections 12.
Abstract:
PROBLEM TO BE SOLVED: To provide a polylactic acid thermoplastic resin composition excellent in mechanical strengths such as impact resistance, heat resistance, etc. by giving mechanical strengths such as practically sufficient impact-resistant strength etc. to the polylactic acid resin. SOLUTION: This polylactic acid thermoplastic resin composition contains 20-95 pts.wt. polylactic acid resin (A) and 5-80 pts.wt. rubber reinforced resin (B) (wherein the total of the polylactic acid resin (A) and the rubber reinforced resin (B) is 100 pts.wt.), and the rubber reinforced resin (B) contains 30-95 wt.% rubber-containing graft copolymer (b-1) and 5-70 wt.% hard (co)polymer (b-2) and the hard (co)polymer (b-2) contains a (meth)acrylic resin component. For a monomer constituting the (meth)acrylic resin component, methacrylate and/or acrylate are preferable. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a papermaking material for a natural fiber molded article, having light weight, producible at a low cost and friendly to the natural environment owing to a high content of natural fiber materials, and giving high mechanical strength. SOLUTION: The papermaking material 1 for a natural fiber molded article is obtained from a water-dispersion containing dispersed natural fibers 2, 4 having binder resin powder 6 attached to circumference of the fibers, by filtering the water-dispersion with a wire cloth and dehydrating and drying the obtained web. The content of the natural fibers 2, 4 in the molded article exceeds 50 wt.% and the binder resin powder 6 bonds the mutually entangled natural fibers 2, 4 at each contacting point in a hot compression molding performed as a post-process.
