polymerizing diol and dicarbonic acid or its ester-forming derivatives, at the last stage of which or at the initial stage of addition- condensation stage, compd. of the formula (I) (where A1: carboxylic group or its ester-substitute type, R1: organic group of 1 valence, X: hydroxyl group, M: alkali earth metal such as manganese, cobalt, zinc or nickel, n1: 0 or 1, R2,R3: compd. containing aliphatic hydrocarbon with carbon no. 1-8, n2: 1 or 2) is added in the amount of 3.0-8.0 wt.% per polymer, while 2.0-5.0 wt.% of silica sol containing silica of av. particle diameter of 150-200 nm being also added; melt-spinning. The woven fabric from these fibers is alkali treated after wards.
