The present invention provides a method of producing a softening agent in which a silicone resin containing particular functional groups, a particular emulsifier and a particular antistatic agent are dispersed stably in an aqueous medium in a particular ratio, and which can give durable slippery touch, softness and processability at the same time to fibers after treatment. The invention also provides an industrially advantageous method of producing acrylic fibers which have animal hair-like touch and processability by one-step treatment, by fixing said softening agent to the acrylic fibers.

Softening agent and method of producing acrylic fiber having animal

Process for imparting an animal hairlike hand to acrylic fibers by mixing a silicone resin and a polyoxyethylene alkylphenyl phosphate while adding water thereto to form an emulsion of weak acidity, applying the emulsion to swollen gelly acrylic fibers, drying the resultant fibers and applying a spinning oil to the dried fibers.

Process for producing acrylic fibers having animal hair-like hand

Acrylic synthetic fibers having an interfiber entanglement coefficient of 10-40, an interfiber entangling force after hot-water treatment of not greater than 50 mg and a specific type of silicone resin deposited on the surfaces of the fibers.
