“…However, as the tensile strength correlates with specimen length, i.e., the probability of attaining high strength values increases with decreasing lo values, we used quite high values to minimize this effect. 23 The material testing machine automatically printed the crosshead travel to the fracture point and the maximum force attained. This crosshead travel was used to determine the tensile elongation t b and the maximum force to determine the ultimate tensile strength u.…”

SynopsisOur work dealt with the spinnability of the commercial liquid crystal polymer Vectra A900 (Celanese Speciality Operations, Ltd.) . The nonisothermal spinning was carried out using a pilotplant scale equipment and a monofilament die. The mass flow rate was constant while take-up velocity was varied between 200 and 1100 m min-' and spinning temperature between 287 and 327OC. In the light of results it seems that the spin-draw ratio is of little importance insofar as it is over 30, albeit the best tensile strengths and modulis were obtained with the highest spin-draw ratio. The fibers showed the inhomogeneity in particular with high spinning temperatures. A SEM analysis of the fibers also showed that high spinning temperature is apt to produce defects in the fibers.
