Abstract
Ba
2+ pre-crosslinked carrageenan fiber (Ba/CAF) was prepared by adding a small amount of Ba
2+ 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 BaCl
2 solution (combine B) and low concentration BaCl
2 solution (combine C), as coagulation bath and stretch bath, respectively. The combination of coagulation bath and stretch bath suitable for Ba
2+ pre-crosslinking wet spinning was screened. The results showed that Ba
2+ can induce the birefringence of the CA molecular chain, and the Ba
2+ pre-crosslinking effect is the best when the CA mass fraction is 8.0 wt%. From the perspective of production safety, fiber performance and spinning cost, the coagulation bath of 3.5 wt% BaCl
2 solution and stretch bath of 1.7 wt% BaCl
2 solution, that is, combination C with low concentration BaCl
2 solution, is the best choice. Ba/CAF-8.0/C was obtained under the best conditions. The linear intensity, water absorption and flame retardancy study showed that the breaking strength of Ba/CAF-8.0/C is as high as 1.61 cN/dtex, the water absorption was 649.2% and 574.3%, in deionized water and normal saline, respectively, and the LOI value reached 32.
