Drying Process Effects on Rayon Fibers

摘要

Rayon fibers are dried on both drum dryers and conveyor dryers, but most fiber producers today use conveyor dryers. Contemporary conveyor dryers are large, multi-stage, multi-zone pieces of equipment approximately 160 to 325 feet (50 to 100 meters) long. Rayon producers can manipulate several process parameters to achieve the final moisture targets. Three of the most direct parameters for producers to manipulate are: 1. Process air temperature. 2. Product retention time. 3. Process air speed.
