ABSTRACT:
Provided is a method for manufacturing a regenerated collagen fiber and a drying apparatus therefor in a manufacturing process of a head decorating regenerated collagen fiber, the method enabling suppression of fluff (fiber breakage) and process trouble and providing outstanding curl retentive property and little hackling loss. Continuous drying is performed while controlling a tension of a fiber bundle under drying, the fiber bundle introduced into the drying apparatus having twists, using an apparatus having a mechanism wherein driven rollers are installed in an entrance and an exit, either of the driven rollers in the entrance and the exit is rotated at a constant speed, a fiber tension is detected with a tension detecting element installed in a drying chamber side of an exit driven roller, a rotational speed of the driven roller in another side is controlled so that an exit tension gives a desired value, and a freely rotatable roller is installed at a predetermined interval between the exit and the entrance.
