Abstract:
Cellulose acetate filaments with a trilobal cross section and a degree of substitution of about 2.1 to 3.0, wherein the filaments have a titer of less than 3.3 dtex, a PE form factor of less than 0.320 as well as a KH form factor of less than 0.560, the form factors being defined by the following ratios:PE=4.pi.A/P.sup.2 and KH=A/A.sub.k,wherein A=cross-sectional area of the filament, P=circumference of the filament cross section and A.sub.k =area of the convex shell of the filament cross section.
