Abstract: Spinning solution was prepared with collagen and PVA blending by addition of glutaraldehyde as
cross2linker. CollagenPPVA composite as2formed fiber could be produced via wet spinning. After heat drawing ,
heat setting , and acetalization , the collagenPPVA composite fiber was obtained. The composite fiber had
strength 3. 74 cNPdtex , modulus 44. 60 cNPdtex , elongation 31. 30 % and crystallinity 60. 79 %. The value of
stick point in water was 105 ℃, and the moisture regain was 8. 9 %. According to SEM photographs , cross2
section of the composite fiber had a few of holes and cracks , these defects diminished with increasing the sold
content of the spinning solution.
