are manufactured to mimic this trilobal shape to give them a silk-like appearance. Filaments with a round cross section have less brilliance than trilobal filaments.

Etymology

is a combination of the words "Tri" for three and "lobal" for sides.

Use

Synthetic fibers are particularly suitable for specific effects such as crimping and texturizing due to their adaptability during production. Trilobal cross section helps alter texture and several physical attributes such as strength and static properties, in addition to providing brightness to the fibres. The trilobal cross sectional shape helps to reduce manufacturing defects in filaments.
