The invention discloses a deodorizing nylon fiber. The deodorizing nylon fiber contains 0.5 to 5wt% of a functional mixture and 95 to 99.5% of a polyamide elastomer; the functional mixture at least contains titanium dioxide with an average particle size of 0.1 to 3m, tourmaline powder, and natural bamboo charcoal. Ammonia gas absorption rate of the deodorizing nylon fiber is higher than 80%, and isovaleric acid absorption rate is higher than 95%; and ammonia gas absorption rate of the fabric containing the deodorizing nylon fiber is higher than 80%, and isovaleric acid absorption rate is higher than 95%.
