摘要: Wet tows of filaments are dried on rotating drums at temperatures between 80* C. and 220* C. the surfaces of the drums having protuberances, for example in the form of wire fabric coverings, so that the vapors being formed between the two and the drum surface are able to escape through the interconnected cavities between the protuberances. Such drying of the tows imparts hardness to the handle of the fibers.
