摘要： PROBLEM TO BE SOLVED: To prepare the subject material, having excellent durability, capable of exhibiting both antibacterial and fungicidal effects in extremely efficient manner and excellently effecting even against highly dense microbial pollution by using fibers containing a metal salt of a specific organic compound having fungicidal activity by itself. SOLUTION: This material is obtained by compounding an ion-exchange fiber of a polystyrene, a polyacrylamide a polyamide, carboxymethyl-modified cellulose, etc., with an antibacterial and fungicidal agent comprising a metal salt (preferably, a salt of silver, copper or zinc) of an organic compound such as a benzimidazole compound or a mercaptopyridine-N-oxide compound. For instance, one to three kinds selected from a silver salt, a copper salt and a zinc salt are added to a carboxymethyl- modified cellulose, and a compound selected from the antibacterial and fungicidal agents, an isothiazolone compound, a benzothiazole compound and a benzothiazolone compound is added into the salt-added carboxymethyl-modified cellulose under the condition of pH5-8. The obtained material is hardly soluble and highly stable, and the loss of the antimicrobial effect by water washing is extremely little. The material can be used as an air filter, a filter medium for an electric discharge machine filter or a liquid filtration medium.

摘要： PURPOSE:To provide a low cost method of manufacturing a coffee filter paper with improved filtering speed to be used for an automatic vending machine. CONSTITUTION:A pulp slurry blended over 30 deformation per cent with a cellulosic natural fiber whose cross sectional deformation is less than 1.2 is used as a raw material where cationic fixative, anionic fixative, alkyl ketene dimer, etc., are added so that the zeta potential of the slurry is maintained with the range of over -5mV and less than +5mV. A coffee filter paper with a bass weight of 25g/m is thus manufactured by this method.

摘要： PURPOSE:To handle easily and prevent foreign matters from getting mixed into extrusion liquid or the like by making a sheet by employing fiber pieces of far infrared ray radiating fiber as a paper making material or mixing the fiber pieces of far infrared ray radiating fiber and fiber pieces of another paper making material and constituting subject filter paper. CONSTITUTION:A filter paper 7 is formed by making fiber pieces 3 of far infrared ray radiation fiber as a paper making material and mixing the fiber pieces 3 with the fiber pieces 5 of another paper making material to constitute, for instance, a paper filter 1. In filtering the liquid, the radiation effect of far infrared rays can be actuated sufficiently. As the fiber pieces 3 are used for making the sheet, the fibers are entangled each other to eliminate the fall-off of fiber pieces 3. Also, as the fine particles of a far infrared ray radiation substance are retained firmly as fibers, the fine particles themselves are not fallen off. As the result, it is not required to pay special attention for transportation, preservation and the like of the filter paper, and handling of the same is easy.
