摘要： A process for the production of acrylic fibers, in particular a spinning process for obtaining precursor fibers of carbon fiber by the wet spinning of a polymer solution in an organic solvent and the relative apparatus.

摘要： A process for the recovery and recycling of unreacted monomer in a one-step process for the production of a carbon-fiber precursor. An integrated and improved single-step process for the production of a carbon-fiber precursor is also described, which starts from the co-monomers and reaches the spinning step obtaining the final precursor fiber, which provides for the recovery of the unreacted monomers at the end of the polymerization step and their recycling to the polymerization process itself.

摘要： An integrated and improved, single-step, process for the production of a carbon fiber precursor is described, specifically a process which starts from the comonomers and reaches the spinning step, obtaining the final precursor fiber.
