Process for producing acrylic fibers having animal hair-like hand

Claim 1

A process for preparing acrylic fibers having an animal hairlike hand which comprises preparing an emulsion of pH 5.5 to 6.8 consisting essentially of (1) a silicone resin of the formula ##STR2## wherein R is R'NH 2 , R'NHR" or R'NR" 2 , R' is (CH 2 ) n , n is 1 to 3, R" is C m H 2m +1 , m is 1 to 3, x and y are positive integers and the molecular weight of the silicone resin is less than 100,000 and (2) an emulsifier selected from the group consisting of polyoxyethylene (n') monoalkylphenyl phosphates, wherein n' is the number of ethylene oxide groups and is a value of 5 to 15, and the alkyl group contains 8 to 12 carbon atoms, and (3) water, depositing said emulsion on undried wet-spun swollen gelly acrylic fibers containing 40 to 100% by weight of water based on the dry weight of the fibers, in an amount of 0.1 to 3.0% by weight of the silicone resin based on the dry weight of the fibers, immediately drying the resultant fibers to fix said silicone resin on the fiber surfaces and applying a spinning oil agent to the dried fibers.
