A composition for treating synthetic fibres comprises a lubricant in an amount of from 65 to 94% by weight of the composition, a non-ionic surfactant in an amount of from 5 to 20% by weight of the composition, and an amphoteric surfactant in an amount of from 0.1 to 5% by weight of the composition, wherein said amphoteric surfactant comprises of one or two compounds selected from the group consisting of carboxybetain-type amphoteric surfactants shown by Formula (1) given below, and amino-acid-type amphoteric surfactants shown by Formula (2) given below:
wherein R1 is an alkanoyl group having from 8 to 22 carbon atoms or an alkenoyl group having from 8 to 22 carbon atoms; R2 is H or a methyl group; R3 and R4 are each independently an alkyl group having from 1 to 4 carbon atoms; R5 is an alkyl group having from 8 to 22 carbon atoms or an alkenyl group having from 8 to 22 carbon atoms; R6, R7, R8 and R9 are each independently an alkyl group having from 1 to 4 carbon atoms; Y is N or P; and n is an integer of 2 or 3. The composition is useful in a method of treating synthetic fibers, particularly false-twisting and drawing processes, comprising the steps of: causing an agent to be adhered to the synthetic fibers so as to be present in amount of from 0.1 to 3% by weight of spun synthetic fibers; and thereafter simultaneously carrying out drawing and false-twisting processes on said spun synthetic fibers.
