Abstract
A finish for acrylic fiber consists essentially of: (A) an ethoxylated alkyl phenol; (B) a neutralized partial ester of phosphoric acid and an aliphatic monohydric alcohol; and (C) a mixture consisting essentially of (1) mineral oil; (2) an ethoxylated aliphatic monohydric alcohol; and (3) a neutralized partial ester of phosphoric acid and an ethoxylated aliphatic monohydric alcohol.

A finish for acrylic fiber consisting essentially of:
- (A) an alkyl phenol which has been ethoxylated with from about 40 to about 200 moles of ethylene oxide;
- (B) the neutralized reaction product of
- (1) about 3 moles of an aliphatic monohydric alcohol having from 14 to 22 carbons, and
- (2) about 1 mole of P.sub.2 O.sub.5 ;
- and
- (C) a mixture consisting essentially of
- (1) about 60 to 80 percent by weight of mineral oil having a viscosity of between about 50 and 150 Saybolt Universal Seconds at 100.degree. F;
- (2) about 25 to 10 percent by weight of an aliphatic monohydric alcohol having 10 to 18 carbons, which has been ethoxylated with about 2 to 4 moles of ethylene oxide;
- and
- (3) about 15 to 10 percent by weight of the neutralized reaction product of
- (a) about 3 moles of an aliphatic monohydric alcohol having from 8 to 14 carbons, which has been ethoxylated with about 2 to 9 moles of ethylene oxide, and
- (b) about 1 mole of P.sub.2 O.sub.5 ;
- wherein the amount of component (C) is between about 5 and 70 percent by weight of the composition with the remainder thereof being a composite of components (A) and (B) in a weight ratio of component (A) to component (B) of between about 5/95 and 60/40.
