In Situ Polymerization Process of Negative Oxygen Ion Nylon Fibers
By using in situ polymerization method,the negative oxygen ion slurry prepared by liquid-phase grinding was added to the hydrolysis polymerization reaction of caprolactam to prepare negative oxygen ion nylon 6 with high release of negative oxygen ions.It was sliced and melt spun to obtain negative oxygen ion nylon fibers.The results showed that the optimal process conditions for the polymerization reaction of negative oxygen ion nylon 6(30 L)were:catalyst phosphoric acid mass fraction 0.08%,deionized water mass fraction 7%,negative oxygen ion slurry mass fraction 0.8%,and acetic acid mass fraction 0.1%.The negative oxygen ion release rate of the prepared nylon fiber was 1380/cm3,which reached the high negative oxygen ion release index.
