摘要
Bicomponent fibers were wet-spun from soybean protein and poly (vinyl alcohol). The fiber was brittle and showed a high frequency of breakage upon drawing and the bad compatibility between soybean protein and poly (vinyl alcohol) was thought to be the causes for the poor drawability. Our effort was then to study the soybean protein and poly (vinyl alcohol) solution, with the aim of trying to improve the components’ compatibility and to determine the proper solution condition for dissolving them. The effects of alkali, sodium sulfite and urea on the compatibility of the solution were examined.
