PROBLEM TO BE SOLVED: To obtain a subsidiary material excellent in air permeability and shape retention by forming a particle of a specific particle diameter which contains a specific amount or more of microfibrillated cellulose. SOLUTION: A particle with a particle diameter of 2-50 mm which contains 50 wt.% or more of microfibrillated cellulose is prepared. The microfibrillated cellulose preferably has a viscosity of 200 mpa.s or more and a stability of suspension of 70 or more and is desirably obtained by using regenerated pulp. After the water content is adjusted to 50-99%, it is pelletized into a particle. A water-absorbing agent may be added in addition to the microfibrillated cellulose. Furthermore, fiber and paper opened into cotton may be added. Those which may be added are desirably biodegradable. A particle may be obtained by laminating the micofibrillated cellulose to fabric sheet and shredding the same. Alternatively, the microfibrillated cellulose may be expansion molded and then shredded to obtain a particle. | ||||||

<P>PROBLEM TO BE SOLVED: To obtain a highly transparent fiber-reinforced composite material comprising a cellulose fiber assembly of 4 to 200 nm average fiber diameter impregnated with a matrix material so as to realize not only improvement in hygroscopicity attributed to cellulose fiber but also transparency enhancement. <P>SOLUTION: The fiber-reinforced composite material is obtained by impregnating a cellulose fiber assembly with a matrix material. The hydroxyls of cellulose fibers are chemically modified through reaction with one or two or more chemical modifying agents selected from the group consisting of an acid, alcohol, halogenating reagent, acid anhydride and isocyanate so that the ratio of functional groups introduced by the chemical modification is in the range of 5 to 40 mol% based on the hydroxyls of cellulose fibers before the chemical modification. By virtue of the chemical modification of hydroxyls of cellulose fibers, the hydrophilicity of cellulose fibers can be reduced to thereby reduce the hygroscopicity of fiber-reinforced composite material. Further, the affinity between cellulose fibers and matrix material can be enhanced to thereby attain a transparency enhancement. <P>COPYRIGHT: (C)2007,JPO&INPIT | ||||||
