โœฆ Synopsis

The high-temperature zone-drawing (HT-ZD) method was applied to nylon 46 fibres to improve their mechanical properties. The HT-ZD treatments were carried out three times at different temperatures between 200 and 235ยฐC. The draw ratio and crystallinity increased stepwise with the processing, and those of the HT-ZD3 fibre were 5.6 times and 51%, respectively. The HT-ZD3 fibre finally obtained had a Young's modulus of 7.2 GPa and a tensile strength of 1.0 GPa. The dynamic storage modulus (E') increased stepwise with the processing as well and was 8 GPa at 25ยฐC for HT-ZD3 fibre. ~ยฃ) 1997 Elsevier Science Ltd.

To prepare high-modulus fibers, the vibrating hot-drawing and zone-annealing methods have been applied to nylon 6. The vibrating hot drawing was repeated two times, increasing the applied tension; further, the zone annealing was superposed on the vibrating hot-drawn fibers. The superstructure and me
