Abstract Ba2+ pre-crosslinked carrageenan fiber (Ba/CAF) was prepared by adding a small amount of Ba2+ to the carrageenan (CA) solution as the spinning solution. Ba/CAF-n/A, Ba/CAF-n/B and Ba/CAF-n/C were prepared with ethanol solution (combine A), high concentration BaCl2 solution (combine B) and low concentration BaCl2 solution (combine C), as coagulation bath and stretch bath, respectively. The combination of coagulation bath and stretch bath suitable for Ba2+ pre-crosslinking wet spinning was screened. The results showed that Ba2+ can induce the birefringence of the CA molecular chain, and the Ba2+ pre-crosslinking effect is the best when the CA mass fraction is 8.0 wt%.… More >
