Study on Spinnability of UHMW/PAN Dope in DMSO

Abstract:

The extensional rheological properties of the PAN/DMSO spinning solution using ultrahigh molecular weight (UHMW) PAN as additive were studied. The effects of the additive content on the extensional rheological curve, the extensional viscosity, as well as the spinnability of the PAN/DMSO spinning solution were investigated. The results revealed that the spinnability was related to such factors as solution concentration, additive content, temperature, apparent extensional viscosity and extensional strain rate. The effect of additive on the spinnability of the spinning solution turned out to be small when additive contents were set at a very low level. The spinnability of the spinning solution was optimized when the additive content was 0.5%wt, while the spinning solution adding 1%wt additive had a good spinnability only at a relatively higher temperature.
