A dyeable polyamide fiber is prepd. by adding 0.01-3.0 wt.% diamino alcohol of formula, H2N-(CH2)n-NH-R-OH (where n-1-10, R= alkylene of less than C5), w.r.t. produced polyamide during the polymerization; and spinning and stretching the obtd polyamide as a chip. Pref. the diamino alcohol cpd. is 2-(2-amino ethyl amino) ethanol or 2-(2-amino ethyl amino) isopropanol. The obtd. poly amide has good UV- durability, anti-pollution properties to absorption of Fe in water- treatment, washing-durability and frictiondurability
