Antibacterial degradable vinylon and production method thereof

[0022] Prepare spinning solution:

[0023] Polyvinyl alcohol 17-99 with a degree of polymerization of 1700-1800, boric acid and nano-complexed copper with a solid content of 10% are dissolved in hot water at 80°C to form a plastic chelate as a spinning solution; among them, polyvinyl alcohol The mass percentages of vinyl alcohol, boric acid, water and 10% solid content of nano-complex copper are 15%: 0.6%: 84.35%: 0.05%, respectively.

[0024] Coagulation spinning:

[0025] After the spinning solution is extruded through the spinneret, the sprayed spinning is coagulated in the alkaline coagulation bath formed by sodium sulfate and sodium hydroxide to obtain vinylon filaments; among them, the sodium sulfate and sodium hydroxide in the alkaline coagulation solution The dosages are 280g / L and 80g / L respectively, and the coagulation time is 8 seconds, so as to realize the dehydration and filamentation of vinylon fibers.
