Claims: What we claim is:

1. An acrylic synthetic fiber in which the interfiber entanglement coefficient is from 10 to 40 and the interfiber entangling force after hot water-treatment is not more than 50 mg., said fiber having a silicone resin of the formula ##EQU3## wherein R is R'NH.sub.2, R'NHR" or R'NR".sub.2, R' is CH.sub.2n, n is 1 to 3, R" is C.sub.m H.sub.2m.sub.+1, m is 1 to 3, x and y are positive integers and the molecular weight of the silicone resin is not more than 100,000

deposited on the fiber surface in an amount of 0.1 to 3.0 % based on the dry weight of the fiber.

2. An acrylic synthetic fiber according to claim 1, wherein the silicone resin is applied to the fiber in the form of an aqueous emulsion containing an emulsifier selected from the group consisting of polyoxyethylene(n)alkylphenyl phosphates wherein n is the polymerization degree of polyoxyethylene and is an integer of from 5 to 15.
