Process for conditioning synthetic fiber material

摘要

The conditioning of synthetic fiber material to produce perfect products with a low residual solvent content using comparatively small quantities of steam is carried out in a steam-tight conditioning apparatus consisting of several zones with a rotating perforated belt, using steam which has been superheated to temperatures of from 105 DEG to 150 DEG C., and the material having a residence time in the apparatus of more than 3 minutes.
