Abstract
A method for applying a low soil finish to spun synthetic textile fibers comprising applying to the spun fibers a low soil finish composition containing a dry, waxy solid component which comprises one or more of the following: A) a bisamide of the formula ##STR1## wherein R and R" can be the same or different and are straight or branched alkyl groups having from 7 to 19 carbon atoms, R' is a C.sub.2 -C.sub.4 linear alkyl group, and x is an integer of from 0 to 5; B) a block copolymer of ethylene oxide and propylene oxide; pa C) the reaction product of a C.sub.8-20 saturated fatty alcohol, a C.sub.8-20 saturated fatty amine, or a phenol, with from 2 to 250 moles of ethylene oxide, and D) a C.sub.8-22 fatty acid ester.
