Popis:	The effect of spinning conditions on the material parameters elongation at break, tenacity and modulus was investigated. To achieve higher values of tenacity and modulus, a jet draw rate of 2 and plastic drawing ratio of 1.5 to 2.0 were found to be optimal. Also the increase of fibre length at stress-free heating has been studied. With varying jet draw rate and plastic drawing ratio both positive and negative changes of fibre length were observed. The results are explained by superposition of spontaneous extension and shrinkage
