摘要： PROBLEM TO BE SOLVED: To provide a method for producing pulp capable of easily pulping non-woody plants in high yield without requiring a specific apparatus such as a pressure digesting apparatus and the like. SOLUTION: This production of pulp of non-woody plants is specific in removing lignin included in non-woody plant with a chlorine dioxide-containing agent, especially to pass through a process for heat treating the non-woody plant fibers in an aqueous alkali solution and subsequently soaking the fibers in an aqueous solution of chlorine dioxide, soaking the non-woody plant fibers in an aqueous solution of chlorine dioxide and subsequently heat treating the fibers in an aqueous alkali solution and soaking the non-woody plant fibers in an aqueous solution of a hypochlorite and subsequently soaking in an aqueous solution of chlorine dioxide or treating to age the fibers by boiling in an aqueous alkali solution.

摘要： PROBLEM TO BE SOLVED: To prevent contraction of the spacer in the initial stage of sintering of a ceramic material from being caused by using the spacer comprising a fiber sheet that consists essentially of carbon fiber and fibrillated fiber, a ceramic powder and an organic polymer compound. SOLUTION: In this manufacture, a ceramic powder is added to a fiber sheet contg. carbon fiber in a 15 to 50wt.% ratio by weight, in an amount equivalent to 10 to 40wt.% of the weight of the sheet, and further, an organic polymer, or preferably, a polymer obtained from a monomer having a polymerizable vinyl group is blended into the resulting fiber sheet contg. the ceramic power, in an amount equivalent to >=8wt.% of the total weight of the fiber sheet and ceramic powder. As the carbon fiber, polyacrylonitrile or pitch-based carbon fiber is used and its appropriate diameter and length are 5 to 20μm and 4 to 9mm, respectively. In a paper machine shown by the figure, a slurry A consisting of plural kinds of fiber is charged into a vessel 9 in a cylinder wet part 7 to form a wet paper, and then, another slurry B formed by dispersing a ceramic powder in water is supplied to the wet paper from a sprinkler 18 in a short wire part 8. Thereafter, the wet paper is dried to form a base paper and a polymer compound is impregnated into the base paper.

摘要： PROBLEM TO BE SOLVED: To obviate the presence of microorganisms in and on paper during use and extremely decrease skin injuries by microorganisms by compounding antimicrobial fillers and inorg. fillers at ratios of prescribed pts.wt. with raw materials consisting essentially of vegetable fibers to object the materials and forming the paper. SOLUTION: At least one kind selected from bast fibers, consisting of manila hemp, flax, jute hemp, sisal hemp, etc., or wood pulp are preferably used at >=50wt.% as the raw materials. The raw materials are prepd. by beating the raw materials to a specified degree of beating by a beating machine, such as beater. Further, the zeolite antimicrobial agents are mixed at 0.2 to 10 pts.wt. and the inorg. fillers, such as talc, at 0.5 to 40 parts. wt. with these raw materials and are uniformly dispersed therein. When the paper is made therefrom as it is, the fixing of the fillers on the fibers is poor and the problem of drainage and the contamination of stages arise and, therefore, fixer 'Firex RC (R)' 104 and 'Firex M (R), etc.' are thereafter used to improve the fixability to the fibers. The paper having a basis weight of 15 to 30g/m is then produced by a cylinder paper machine, short endless screen paper machine and Fourdrinier paper machine, etc.

摘要： PROBLEM TO BE SOLVED: To improve the operability without cutting on the way at the time of operating a tape binder by mixing a binding tape with other paper material so that Japanese paper material such as Manila hemp, paper mulberry, Y-form are mixed at a specific ratio, and setting the basis weight, thickness and density to specific values. SOLUTION: This binding tape 10 is so mixed with other paper material that Japanese paper material such as Manila hemp, paper mulberry and Y-form become to 50 to 100%, machine made, paper made, its basis weight is set to 40 to 70g/m , the thickness is set to 0.060 to 0.090mm, and the density is set to 0.60 to 0.80g/cm . Strong roughness such as sufficient tensile strength is obtained according to the ratio of occupying the material. If the basis weight is less than 40g/m , the strength for raising the end 10a released from a release sheet 12 is eliminated, and simply cut. If the thickness is thinner than 0.060mm, it is simply cut at the time of lifting by a punching cutter. If the density is lower than 0.60g/cm , its drape is obviated to be simply cut.

摘要： PURPOSE: To stably obtain a sheet of desired color with fastness to water by imparting a fibrous sheet-like product with a cationic direct dye solution followed by treating the resultant product with an anionic substance dispersion containing a water repellent. CONSTITUTION: First, a fibrous sheet-like material comprising fibers or pulped fibers having affinity with direct dye such as cotton linter or kraft pulp is impregnated or coated with an aqueous solution of a cationic direct dye having azo compound residue and cationic group in its molecule and capable of forming an intramolecular or intermolecular salt, and then dried. Subsequently, the resultant sheet-like material is impregnated or coated with a dispersion containing an anionic polymer such as CMC, an anionic substance such as tannic acid or a derivative therefrom, and an anionic or nonionic water repellent such as a fluororesin capable of forming a stable dispersion together with the above compounds, and then dried, thus accomplishing the water-repelling and dye-setting treatment of the resultant color sheet.

摘要： PURPOSE:To obtain a lightweight prepreg with natural fibers as reinforcing material, having practically sufficient mechanical strength and modulus, excellent in impact resistance and vibration damping, moldable into thin-walled or small- diameter tubular forms, and high in producibility. CONSTITUTION:Firstly, an epoxy resin composition is prepared by incorporating Japanese paper with 30 pts.wt. of a bisphenol A-type epoxy resin, 70 pts.wt. of bisphenol F-type epoxy resin, 4 pts.wt. of dicyanamide (DICY) as a curing agent and 4 pts.wt. of dichlorophenyl dimethylurea (DCMU) as an accelerator. Next, a mold releasing paper is coated with this composition followed by laminating with paper and then hot contact bonding with a press roller to effect impregnating the Japanese paper with the resin composition, thus the aimed prepreg is obtained.
