Abstract:
A treatment agent for elastic polyurethane fibers comprising a dispersion in which a higher fatty acid magnesium salt represented by the Formula I is colloidally dispersed in a silicone mixture comprising a silicone oil with a viscosity of 5.times.10.sup.-6 to 50.times.10.sup.-6 m.sup.2 /s at 25.degree. C. as a dispersion medium and a dispersant comprising an amino modified silicone, represented by Formula II, at a ratio by weight of said dispersion medium to said dispersant of 100/0.5 to 100/4.5, wherein the amount of said higher fatty acid magnesium salt is 1 to 10 parts by weight per 100 parts by weight of said silicone oil;wherein Formula I is: ##STR5##wherein R.sup.2 and R.sup.3 each represent an alkyl group with 11 to 21 carbon atoms;wherein Formula II is: ##STR6##wherein X.sup.1 and X.sup.2 represent a methyl group or amino modified group represented by --R.sup.4 (NH--R.sup.5)d--NH.sub.2 ; at least one of them is the amino modified group, whereinX.sup.3 represents an amino modified group represented by --R.sup.4 (NH--R.sup.5)d--NH.sub.2 ;R.sup.1 represents an alkyl group with 2 to 5 carbon atoms or a phenyl group;R.sup.4 and R.sup.5 each represent an alkylene group with 2 to 5 carbon atoms;a represents an integer of 25 to 400;b represents an integer of 0 to 200, subject to the limitation that 25.ltoreq.a+b.ltoreq.400,c represents an integer of 1 to 5; andd represents 0 or 1.
