    摘要： A dope (15) is prepared with using TAC as a polymer. The dope (15) is transferred with heated by a transferring device (30). A heating medium (36) is used to heat the dope in the transferring device (30). A passage (35) for the heating medium (36) is formed between a cylinder (31) and a jacket (34). The jacket (34) is attached to flanges (32), (33) so as to form a full jacket. When the heating medium (36) is fed in the full jacket, a temperature of the flanges (32), (33) becomes equal to a temperature of the cylinder (31). Accordingly, temperature profile of the dope (15) becomes small, because there is no low temperature portion in the transferring device (30). Therefore, gelatinous material, which is caused by association generated on the low temperature portion, is not in the dope (15).

    摘要： An low concentration dope is fed through a nozzle into a concentrating apparatus, and flash evaporation of the low concentration dope is performed at an end of the nozzle. The low concentration dope is concentrated thereby to an concentrating dope which is contained and heated in the concentrating apparatus. Thus part of solvents of the low concentration dope and the concentrating dope is evaporated to a solvent gas. The solvent gas is cooled and condensed in a condensing section of the concentrating apparatus, and thereafter drawn through a first exit from the concentrating apparatus. The concentrating dope is concentrated to a high concentration dope, which is drawn through a second exit from the concentrating apparatus.

    摘要： The solution film-forming method is provided in which the absolute filtration accuracy for a cellulose acylat solution can be improved and filtration throughput can be increased without reducing the pore size of a filtering material. A dope stock solution to be filtrated is first introduced into a body feed tank and a filter aid from a filter aid tank is added and dispersed. As the filter aid, an aid including SiO2 in 50% or more and a cellulose-based aid are mixed for use. The dope stock solution in which the filter aid is dispersed is introduced into a filter machine and subjected to filtration while forming a cake on the surface of the filtering material. After the filtration, a cleaning solvent is supplied in circulation from a cleaning solvent tank, and the cake is discharged as slurry. The filter aid is separated from the slurry by a separating device and burned in a burning device. Then, a regenerated filter aid is sent to the filter aid tank. After the cleaning, a precoat liquid in which the filter aid is dispersed is supplied from a precoat tank to the filter machine to form a precoat layer on the surface of the filtering material.
