Abstract: An antibacterial antifungal fiber structure is provided, which comprises a polyester mixed fiber structure, and an antibacterial antifungal agent (A) and an antibacterial antifungal agent fixation aid (B) contained in the polyester mixed fiber structure, wherein the antibacterial antifungal agent (A) comprises a pyridine antibacterial antifungal agent, wherein the antibacterial antifungal agent fixation aid (B) comprises at least one compound selected from a first group (b1) comprising a surfactant, a second group (b2) comprising an organic solvent, and a third group (b3) comprising an aromatic compound and a urea compound. The antibacterial antifungal fiber structure is excellent in antibacterial and antifungal properties because the antibacterial antifungal agent (A) is fixed together with the antibacterial antifungal agent fixation aid (B) in fibers of the polyester mixed fiber structure.

Abstract: According to the present disclosure, a resin product is brought into contact with a treatment liquid containing an antibacterial antifungal compound (A) of a quaternary ammonium salt compound having a molecular weight of not greater than 1500 and, in this state, heat-treated under a normal atmospheric pressure or under an increased pressure, whereby the antibacterial antifungal compound (A) is immobilized on at least a surface of the resin product. Thus, an excellent antibacterial/antifungal finished product having water resistance and laundry durability is provided.

Abstract: The main object of the present invention is to provide a producing method for a 4-isopropyl-3-methylphenol which may be selectively produced, easily refined, and with less odor and coloration. The present invention achieves the object by providing a producing method for a 4-isopropyl-3-methylphenol characterized in that a 4-halogenated-3-methylphenol or a phenol derivative thereof is reacted with an isopropyl metal compound under presence of a catalyst and a solvent.

Abstract: An object of the present invention is to make it possible that a pyridine antibacterial/antifungal agent is dispersed stably in a liquid for appropriate impartation of the pyridine antibacterial/antifungal agent to fibers, and that when fibers are processed with the agent which is mixed with various other treating agents such as dyes and softeners, there is no negative influences on the process of the fibers for imparting antibacterial/antifungal properties. An antibacterial/antifungal properties-imparting agent contains a pyridine antibacterial/antifungal agent; a modified polysaccharide having reduced hydroxyl groups; and a wetting agent; but does not contain a surfactant. After applying the antibacterial/antifungal properties-imparting agent to fibers, the fibers undergo a heating process.
