SPIRAL FILAMENTS AND PRODUCTION THEREOF

摘要

The invention relates to a method for producing spiral filaments, comprising the steps of: - extruding at least one monofilament, - twisting the at least one monofilament about its longitudinal axis under tensile stress, wherein, before and/or during and/or after the twisting of the at least one monofilament and while it is tensioned with respect to its longitudinal axis, a heat treatment takes place, which is configured such that heat setting occurs. Furthermore, the invention relates to a device for producing twisted filaments and heat-set filaments produced thereby.
