Abstract: the invention discloses a spinning process of nitrocellulose cotton. Method And application, the nitrocellulose NC, plasticizer and process solvent are made into spinning raw fluid and added into the spinning kettle, under the pressure of nitrogen or compressed air. spinning The original fluid is extruded from the spinneret on the spinning kettle, and is stretched by gravity in the air layer to form the raw liquid flow. The original liquid flows into the coagulation bath, and then is solidified into the original raw silk of the nitrocellulose under double diffusion. The obtained nitrocellulose precursor is in mechanics. performance The moisture absorption property, burning rate performance and environmental protection of combustion products meet the technical requirements of fireworks and firecrackers, thus replacing the application of paper leads in fireworks and firecrackers, and solving the problem of production safety and environmental protection of paper leads.
