Abstract
An acrylic fiber having applied thereto a polyoxyalkylene aminopolysiloxane compound having a viscosity of from 5 to 500 poises at 25.degree. C. and which is represented by formula (I) as an oiling agent: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, and R.sub.6 each represents a lower alkyl group or an aryl group, PA0 R.sub.7 represents a hydrogen atom, a lower alkyl group or an aryl group, PA0 R.sub.8 represents H or --CH.sub.3, or ##STR2## (wherein R.sub.10, R.sub.11 and R.sub.12 each represents a hydrogen atom, a lower alkyl group or an aryl group), PA0 R.sub.9 represents an alkylene group having not more than 5 carbon atoms, an arylene group, or a single bond, PA0 A represents a group ##STR3## (wherein R.sub.13 and R.sub.14 each represents H, --CH.sub.3, --C.sub.2 H.sub.5), PA0 B represents a group ##STR4## (wherein R.sub.15 : H or --CH.sub.3, and m and n each represents 0 or an integer of from 1 to 10, provided that m+n.gtoreq.1), PA0 X and Z each represents an integer from 1 or more, and W and Y each represents 0 or an integer of 1 or more.
