Owing to its hollow section, Polyteks Hollow Yarns offer innovative characteristics that can be used for technical purposes in several fields.

Hollow Yarns offer comfort since their hollow filaments generate a thermal insulation between the skin and the air keeping the body at the optimal temperature.

These yarns, which are produced by using a special flat section, have a certain %hollow internal volume in the cross section of the fiber. In this way, fabric surfaces consisting of yarns produced provide functional properties such as volume, comfort, low air permeability. In this way, the hollow yarns create thermal insulation between the skin and air and keep the body at optimum temperature.
