Synthetic fibrous structures having a soft feel, an excellent luster and a silky feel are produced by forming composite filaments composed of a polyamide and a component having poor affinity to the polyamide selected from the group consisting of a polyester, polyolefin and polyacrylonitrile into a fibrous structure and treating the fibrous structure with an aqueous emulsion of 1.5-50% by weight of at least one of benzyl alcohol and phenylethyl alcohol and having a percent transmittancy of less than 20%, which is obtained by adding a surfactant to the emulsion, whereby to fibrillate the composite filaments.
