| Abstract: | Soybean protein was modified by acrylonitrile and blend spun with polyacrylonitrile. The soybean protein-modified polyacrylonitrile fiber can be produced with high hydroscopicity via normal production process. The modified polyacrylonitrile fiber had breaking strength 2.75 cN/dtex, elongation at break 25.4% , moisture regain 1.7% and water retention 8.3% at 10% modified soybean protein content when the modified soybean protein with 33% soybean protein was blend spun with polyacrylonitrile dope. |

| Keywords: | soybean protein graft modification polyacrylonitrile fiber moisture regain water retention |
