<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of tatami facing with which loads on environment or persons are reduced by using a water-repellent/oil-repellent agent with C6 telomer as raw material, and paper tatami facing improved in contamination resistance/durability/silence similar to conventional C8 telomer based tatami facing can be manufactured. <P>SOLUTION: A manufacturing method of tatami facing includes (a) forming a base coating layer 14 by coating a surface of tubular paper yarn 10 obtained by twisting paper made from woody fibers with a binder resin composition 20 comprised of a cross-linking polymers including a cross-linking group in a main chain or a side chain and then drying the binder resin composition 20, (b) applying water-repellent/oil-repellent work to the surface of the tubular paper yarn 10 by forming a top coating layer 16 by coating the surface of the base coating layer 14 with a water-repellent/oil-repellent agent 22 comprised of a fluoride resin including a side chain of which the terminal is comprised of a perfluorohexyl group and a side chain of which the terminal is comprised of a hydrophilic group, and then drying the water-repellent/oil-repellent agent 22, and (c) weaving tubular paper yarn 12, on which water-repellent/oil-repellent treatment has been performed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
