    摘要： A method for producing an additive for a rubber composition, including the step of preparing modified cellulose fibers including introducing one or more compounds selected from unsaturated group-containing alkylene oxide compounds and unsaturated group-containing glycidyl ether compounds to cellulose-based raw materials in the presence of a base, via an ether bonding, and thereafter carrying out a finely fibrillating treatment, wherein the modified cellulose fibers are cellulose fibers bound to one or more substituents, via an ether bonding, selected from substituents represented by the following general formula (1) and substituents represented by the following general formula (2): —CH2—CH(OH)—R1 (1); and —CH2—CH(OH)—CH2—(OA)n—O—R1 (2), wherein the modified cellulose fibers have cellulose I crystal structure.

    摘要： Methods of making gypsum panels, fiberglass mats, and associated gypsum panels and building sheathing systems are provided. In one aspect, a method of making a gypsum panel includes depositing an aqueous liquid containing a wetting agent onto a fiberglass mat, such that the aqueous liquid penetrates an entire thickness of the fiberglass mat, and depositing a gypsum slurry onto the fiberglass mat onto which the aqueous liquid has been deposited, such that the gypsum slurry penetrates at least a portion of the fiberglass mat. In another aspect, a method of making a gypsum panel includes depositing an aqueous liquid containing a wetting agent onto a fiberglass mat, and depositing a gypsum slurry onto the fiberglass mat onto which the aqueous liquid has been deposited, prior to drying of the aqueous liquid, such that the gypsum slurry penetrates at least a portion of the fiberglass mat.

    摘要： Provided are a sizing agent coated carbon fiber bundle that has excellent mechanical characteristics when used as a carbon fiber reinforced composite material, as well as excellent ease of handling; a method for manufacturing the same; and a prepreg and carbon fiber reinforced composite material of excellent mechanical characteristics, employing the fiber bundle. The carbon fiber bundle is coated with a sizing agent that includes a polyether aliphatic epoxy compound having two or more epoxy groups per molecule and/or a polyol aliphatic epoxy compound or a non-water-soluble compound having a glass transition temperature of −100-50° C., wherein the sizing agent coated carbon fiber bundle is characterized in that the flatness ratio (width/thickness) of the carbon fiber bundle cross section is 10-150, and a two edge part/center part sizing agent deposition ratio, obtained by dividing the carbon fiber bundle in the width direction along the fiber direction into three equal parts by mass, and computing the ratio from the ratio of the mass of the sizing agent to the mass of the carbon fiber bundle in the center part and in both end parts, is 1.05-1.5.
