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 5Ã—10âˆ’6 to 50Ã—10âˆ’6 m2/s at 25Â° C. as a dispersion medium and a dispersant comprising an amino modified silicone and an organic carboxylic acid comprising one or more of mono- to tetracarboxylic acids having 4-22 carbon atoms and having a melting point of 50Â°-220Â° C., wherein said amino modified silicone is represented by Formula II, wherein said amino modified silicone and said organic carboxylic acid are present in a weight ratio of 100/100 to 100/2, and at a ratio by weight of said dispersion medium to said dispersant of 100/0.5-100/4.5, 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: â€ƒwherein R2 and R3 each represent an alkyl group with 11 to 21 carbon atoms; and wherein Formula II is: â€ƒwherein X1, X2, and X3 each represent a methyl group or amino modified group represent by â€”R4(NHâ€”R5)dâ€”NH2; at least one of them is the amino modified group, wherein R1 represents an alkyl group with 2 to 5 carbon atoms or phenyl group; R4 and R5 each represent an alkyl group with 2 to 5 carbon atoms; a represents an integer of 25 to 400; b is an integer of 0 to 200, subject to the limitation that 25&lE;a+b&lE;400; c represents an integer of 0 to 10; and d represents 0 or 1.
