摘要： PURPOSE: To provide a dewatering process of coupled spinning for fibrous material without a problem of transferring the fibrous material by forming a prexifilamentary film-fibril strand and transfer it from a spinning orifice to a dewatering device without stacking an apparatus by cutting the fibrous material into pieces. CONSTITUTION: A polyolefin fiber is obtained continuously by dewatering process of coupled spinning by spinning a solution of polyolefin dissolved in an inorganic solvent into a vertical tube 12 from a spinning nozzle 5 located in an upper section of an elongated vertical vessel 1, removing a volatile material from an upper of the vessel 1, forming a prexifilamentary film-a fibril strand by spraying water into the vessel 1 through spraying nozzles 13 and 14, shredding in a self-cleaning self-feeding shredder 4 through the tube 12, conveying it to a second vessel with water, passing it from an inlet 23 of the second vessel 2 over a baffle 16 to an outlet 24, introducing an inert gas into the vessel 2 through the outlet 24 simultaneously, exhausting residual volatile materials from an exhaust tube 7, sending the fibers into a dewatering device 3 and separating the fibers from the solution.
