Fibre Chemistry Aims and scope

Rheological studies of samples of spinning solutions on a Rheotest 2 viscometer showed that for the same viscosity values determined with the falling ball method, the rheological characteristics such as the flow index, initial Newtonian viscosity, and apparent viscosity, differ. The highest strength of aramid fibres is attained in spinning from a spinning solution with the following rheological characteristics: apparent viscosity of 59.3 Pa⋅sec, initial Newtonian viscosity of 73.2 Pa⋅sec, and flow index of 0.808.
