False twisting ribbons of from 100 to 2,000 denier using a mechanical false twisting spindle rotating at from 10,000 to 500,000 r.p.m. to produce a false twisted ribbon in which the ribbon is longitudinally folded on itself from both sides but contains substantially no twist but rather has embossed striations which give the appearance of a twist.
