| titleOfInvention | Process for the production of acrylic fibers |
| abstract | A process for preparing a homogeneous spinning solution for producing acrylic fibers is described, comprising the following steps: i) a powder homopolymer or copolymer of acrylonitrile at a temperature in the range of 5° C. to 10° C., a mixture of DMSO/water in the range of 94.5/5.5 to 97/3% w/w, preferably DMSO/ at a temperature of 5° C. Preparation of a homogeneous suspension by mixing with a mixture of 95/5 water, said mixing decomposing a stream of DMSO/water solvent for a time in the range of 5 to 30 minutes and premixed powder homopolymers or copolymers of acrylonitrile Carried out by spraying the stream of; ii) heating the homogeneous suspension from step i) to a temperature in the range of 70° C. to 150° C. for a time in the range of 0.5 to 30 minutes until complete dissolution of the homopolymer or copolymer and formation of a homogeneous solution. This spinning solution is then supplied to a storage tank or spinning line. |
