ABSTRACT:
Disclosed is process for producing a bundle of fibrous elements, at least some of which are uneven in the thickness in the axial direction thereof, namely some of which include thick portions having a larger sectional area and thin portion having a smaller sectional area. In these fibrous elements constituting the fibrous bundle, the thick portions have, in general, a higher dyeability than the thin portions, and in the fibrous bundle, these higher dyeability portions are formed substantially randomly at a distribution ratio of at least 300 portions per 10 cm of the length of the fibrous bundle. This fibrous bundle is characterized in that it apparently resembles a fibrous bundle composed of fibrous elements uniform in the thickness and dyeability.
