Abstract: Aiming at high energy consumption in viscose staple fiber production,feasibility of energy-saving of spinbath preparation system was presented by analyzing energy consumption of each process in viscose staple fibre production. The advantages and disadvantages of two kinds of spinbath preparation system:Maurer model and Lenzing model were discussed. An improved energy-saving spinbath process was designed through technical progress and innovation. A new type of multi-stage flash evaporation device was developed. Multi-stage flash evaporation was used to regulate the temperature of circulated spinbath,and the traditional device with crystallization and calcination was replaced by a one-step device with multi-stage flash evaporation for extraction of anhydrous sodium sulfate. The advanced multi-stage flash evaporation simplified the process and saved investment. Industrialized operation showed that energy consumption could be reduced by 23% with obvious energy-saving.

Key words: viscose staple fiber, spinbath, production, evaporation, optimal design
