Abstract: PURPOSE:To obtain the subject filament excellent in abrasion resistance, etc., by curing a hydrolyzate of a specific silicone compound and an epoxy compound with a specified metallic compound and coating the surface of polyester monofilament through an adhesive layer with the resultant cured product in a specific thickness. CONSTITUTION:A silicon compound expressed by the formula (n is 1-3; R is alkyl or alkoxyalkyl; n R may be same or different; R is 1-6C alkyl, etc.; R is 1-10C alkylene, alkylene oxide, etc.; X is functional group containing epoxy group) is hydrolyzed with an acidic aqueous solution. The resultant hydrolyzate and an epoxy compound are cured with a metallic compound selected from iron, chromium, aluminum, etc., and the surface of polyester filament yarn is then coated with the obtained cured product through an adhesive composed of a combination of preferably a copolymer of methyl methacrylate and styrene with trimethyl ether of hexamethylolmelamine, etc., to form a coating layer of 0.5-20mum thickness. Thereby, monofilament excellent in flexibility, etc., is obtained.
