摘要： PURPOSE: To provide a process for producing a colored pattern paper having uniform flexibility over the whole area by a new method without adding a pattern developing step after a paper-making step. CONSTITUTION: A substance capable of flocking pulp is added to a paper-making raw material at a position upstream of the inlet of a Fourdrinier paper machine to flocculate the pulp. A dye solution and/or a pigment solution are scattered on the water surface on a wire immediately after the inlet at a position to have a pulp concentration of 0.1-5wt.% at the initial dehydration step to begin the precipitation of the flocculated pulp on the wire under dehydration. The pulp slurry is subjected to the conventional treatment thereafter to obtain a colored pattern paper.

摘要： PURPOSE:To obtain a separator having small maximum pore diameter, low electric resistance, and long acid resistant life by stacking two layers having different maximum pore diameter and density a by conventional paper making method. CONSTITUTION:A separator is manufactured with acid resistant synthetic fibers, and acid resistant glass fibers, and acid resistant inorganic pigment by a paper making method. The separator consists of at least one layer having a maximum diameter of 45mum or less and at least one layer having a maximum diameter of more than 45mum and a density of below 0.25 g/cm , and these layers are stacked in order or alternately in a paper making process to manufacture the separator. Thereby, the lead-acid battery separator having small maximum pore diameter, long acid resistant life, and low electric resistance can be obtained.

摘要： PROBLEM TO BE SOLVED: To obtain the subject paper useful for bill, etc., without staining a dryer with an adhesive of a thread, by adding a specific thread to a paper layer in paper making so as to alternately expose and embed the thread on the surface of a paper and drying the paper under a prescribed condition. SOLUTION: In producing a paper for preventing counterfeit by adding a thread obtained by providing both the sides of a filamentous or a taped substrate with a thermoplastic and/or a water remoistening adhesive to a paper layer in paper making so as to alternately expose and embed the thread on one side of a paper, in a drying process, the highest temperature TD on the surface of a cylindrical type dryer to be brought into contact with the thread is controlled so as to establish a relationship of the equation (temperature unit is deg.K) between TD and the glass transition temperature Tg of the adhesive layer at the side of the thread to be brought into contact with the dryer to give the objective thread containing paper for preventing counterfeit. Preferably the adhesive layer attached to the side of the thread to be brought into contact with the dryer uses a thread composed of a thermoplastic adhesive having >=60% gel content and 293-318 deg. K of TG.

摘要： PURPOSE: To provide glassine paper for release paper, prevented from generation of the irregular luster of the back surface of the release paper due to the uneven absorption of water. CONSTITUTION: In order to correct curl caused after dried, in a process for using glassine paper as a release paper base material to produce adhesive paper, the back surface of the release paper is subjected to a water-adding treatment with a gravure roll, etc., and the glassine paper is produced by forming barrier layers consisting mainly of polyvinyl alcohol on both the sides of raw paper consisting mainly of wood pulp and subsequently subjecting the processed raw paper to a smoothening treatment. Therein, a water-soluble salt is added to the barrier layers in an amount of 3-10 absolute dry wt.% based on the absolute dry weight of the polyvinyl alcohol. The polyvinyl alcohol composing the barrier layers is especially preferably an imperfectly saponified polyvinyl alcohol having a saponification degree of

摘要： PURPOSE:To reduce cost and increase liquid retention ability and absorbency by making a separator with the mixture of glass fibers having a mean diameter thicker than 5mum, acid resistant synthetic fibers to which hydrophobic treatment is conducted, and water-containing amorphous silica with a paper machine. CONSTITUTION:A separator for sealed lead-acid battery is made with the mixture of 10-30wt% glass fibers having a mean diameter thicker than 5mum, 40-80wt% acid resistant synthetic fibers to which hydrophobic treatment is conducted and in which at least 10wt% beating synthetic fibers are contained, 10-40wt% water-containing amorphous silica with a paper machine. Therefore, cost is reduced by removing expensive fine glass fibers, and liquid retention ability and absorbency are increased by using thicker glass fibers to increase capillary action. Moreover, by using synthetic fibers to which hydrophobic treatment is conducted, dispersion of fibers and mechanical strength are increased. Therefore, battery performance is improved.
