ForewordThis code was formulated by Jiangxi Textile Industry Scientific Designing Institute jointly with organizations concerned according to the requirements of Document JIANBIAO [2006] No. 136 issued by the former Ministry of Construction (MOC)- "Notice on Printing the Development and Revision Plan (the Second Lot) ofNational Engineering Construction Standards and Codes in 2006". During the process of formulating this code, the drafting group conducted extensive investigation, summarized construction experience of viscose fibre plants for over 50 years in China, especially the digestion and absorption of overseas advanced production technology of viscose fibre in recent years, as well as the design, construction and processing experience and lesson of viscose fibre plant in China and extensively asked for opinions, and finalized this code through review. This code comprises 17 chapters and 5 appendixes; it mainly covers general provisions, terms, process design, process equipment, piping, auxiliary production facilities, automatic control and instrument, electrical, general plan, build ing and structure, water supply and drainage, heating, ventilation and air cond itioning, motive power, environmental protection, safety and health, storage and repair of machine and electric installations and instrument. Provisions printed in bold type in this code are compulsory and must be enforced strictly. The Ministry of Housing and Urban-Rural Development of the People's Republic of China is in charge of the administration of this code and the explanation of the compulsory provisions; China National Texti le and Apparel Council is responsible for its routine management and Jiangxi Textile Industry Scientific Designing Institute is responsible for the explanation of specific technical contents. During the process of implementing this code, you are kindly requested to send your opinions and advice to Jiangxi Textile Industry Scientific Designing Institute (Address.
