ABSTRACT:
A low concentration aqueous solution of agent for processing synthetic fibers is produced by preparing acidic alkyl phosphate which is solid at room temperatures and gradually adding this prepared acidic alkyl phosphate with stirring to an aqueous solution containing potassium hydroxide in an amount for partially neutralizing this added acidic alkyl phosphate to obtain 0.1-10 weight % low concentration aqueous solution of agent for processing synthetic fibers containing potassium alkyl phosphate.
