【Abstract】 The reasons of producing waste fibers were introduced, and the experiments of waste fiber solution were made. The results showed that the dopes of many kinds of waste fibers re-solution were mixed with the system, the dope PAN content and rising-bubble viscosity should be selected as 12%～13%, 70～100s, thus the effect of waste fiber on fiber quality was minimum.更多还原
