摘要： A polymer film producing apparatus has a moving support on which dope containing polymer and solvent is cast to form a cast film. The cast film is stripped from the support to obtain a polymer film containing the solvent, and the polymer film is dried. A first gas flow duct has gas nozzles for causing a first dry gas to flow toward the cast film. A second gas flow duct has a gas outlet disposed downstream from the gas nozzles, and positioned higher than a height of the gas nozzles relative to the support, for causing a second dry gas to flow toward the cast film in a moving direction of the support. Furthermore, the first gas flow duct includes a gas blow wall for defining the first flow path by opposing to the support. The gas blow wall has the gas nozzles.

摘要： A dope containing Tac is cast onto a belt. When having self-supporting properties, the dope is peeled as a wet film from the belt, and transported to a tenter dryer. In an entrance section, a preheating is made and in an stretching section a stretching is made at a stretch speed Y(%/min). In a relaxation section, the width of the film was becomes shorter, and in the exit section, the width was kept to be uniform and transported toward the tenter dryer. A difference of a content of the remaining solvent between the stretching starting point and a relaxation end position is X. In this case, the following formula is satisfied to reduce the generation of bowing phenomena. Thus the axial diffractive of a slow axis can be reduced.

摘要： A reducing agent removal line comprises a heat exchanger, an air supply line and a cleaning liquid supply line. The cleaning liquid supply line feeds cleaning liquid into a first passage chamber. The air supply line supplies mixed air of after-drying air containing high-melting point additive and additive containing air containing low-melting point additive into the first passage chamber. Due to contact between the mixed air and a heat-exchanging element, a mixture material containing the high-melting point additive is precipitated from the mixed air. Since melting point MP1 of the high-melting point additive in the mixed air can be controlled to be lower than a temperature of the cleaning liquid by changing a mixture ratio M, the cleaning liquid contacts and dissolves the mixture material in the mixed air.
