    摘要： A process is described for the preparation of a homogeneous spinning solution for the production of acrylic fibers which comprises the following steps: i) preparation of a homogeneous suspension by mixing a powder homopolymer or copolymer of acrylonitrile with a mixture of DMSO/water ranging from 94.5/5.5 to 97/3% w/w at a temperature ranging from 5° C. to 10° C., preferably a mixture of DMSO/water 95/5 at a temperature of 5° C., said mixing being carried out in a time ranging from 5 to 30 minutes, by spraying a stream of the DMSO/water solvent onto a stream of powder homopolymer or copolymer of acrylonitrile, disgregated and premixed; ii) heating the homogeneous suspension coming from step i) to a temperature ranging from 70° C. to 150° C. in a time ranging of from 0.5 to 30 minutes, until the complete dissolution of the homopolymer or copolymer and the formation of a homogeneous solution. This spinning solution is then fed to a storage tank or to the spinning line.
