Abstract
Para-type aromatic polyamide short fibers are attached with a phosphate ester alkali metal salt of an alcohol having a carbon number of 12 having a molar fraction of a monoester salt of from 45 to 70% by mol and a molar fraction of a diester salt of from 10 to 40% by mol in an amount of from 0.05 to 1.0% by weight based on the weight of the fibers, whereby such para-type aromatic polyamide short fibers excellent in spinning property are obtained that are excellent in bundling property and antistatic property, and are low in adhesion property causing less twining on rollers and less formation of scums.
