PURPOSE: An amide of higher fatty acid is added to a copolyamide consisting of caproamide, hexamethylene isophthalamide and others and they are melt spun to form said monofilaments with high mechanical strength and high transparency even in large deniers.
CONSTITUTION: To a copolyamide consisting of (A) (a) 95W75wt% of caproamide ingredient, (b) 5W25wt% of hexamethylene isophthalamide ingredient and (c) 0W 20% of hexamethylene terephthalamide ingredient is added (B) 0.01W2% of at least one of amides, esters and metal salts of higher fatty acids or higher alcohols and they are melt spun. The transparency of the resulting monofilaments is controlled so as to satisfy the equation [T is transparency in %, d is the diameter of the monofilament in mm, ranging from 0.1W4mm.
