| Abstract: | The effects of epichlorohydrin(ECH) treatment and acetalization reaction on the protein retention ratio and softening point in water of collagon/polyvinyl alcohol(PVA) as-spun composite fiber were studied.The results showed that the composite fiber had the softening point in water of 101℃ and the protein retention ratio of 90.33% when the process conditions were as followed: the ECH bath treatment temperature 50℃,time 2 h and pH value of 11 and the acetalization treatment temperature 50℃,time 40 min,180 g/L sulfate and 45 g/L formaldehyde in acetalization bath by mass concentration. |
