摘要：
A semi-empirical model is presented for the calculation of the overall orientation in nematic aramid solutions during the fibre spinning process. The model describes the effect of coagulation-bath temperature, polymer concentration, and draw ratio on the modulus of poly(p-phenylene terephthalamide) yarns. The results of the model are compared with experimental results for the E modulus of as-spun aramid fibres.
