发明名称 Manufacturing method of cellulose ester film
摘要 Disclosed is a method of manufacturing a cellulose ester film according to a solution casting film manufacturing process comprising the steps of casting a cellulose ester dope on a support to form a film on the support, peeling the film from the support, drying the peeled film, and winding the dried film around a take-up spool, wherein the following relationship is satisfied:-4%<=MD-TD<=4%wherein MD is represented by the following formula: MD=(transporting speed of film at the time when the film is wound around the take-up spool/transporting speed of film on the support-1)x100(%), and TD is represented by the following formula: TD=(width of film at the time when the film is wound around the take-up spool/width of film immediately before peeled from the support-1)x100(%)
