MECHANICAL BEHAVIORS OF POLYURETHANE-UREA ELASTOMERIC FIBERS UNDER STATIC STRETCHING DEFORMATION
The mechanical behaviors of polyether (ET) and polyester (ES) soft segment urethane-ureaelastomeric fibers constrained at different levels of elongation have been investigated by means ofdynamic mechanical tests and force-temperature measurements. The dynamjc mechanical re-sponse of the ET urethane-urea showed some difference from that of the ES as a function of exten-sion ratio. For force-temperature measuring the existence of a low temperature transition corre-sponding to the glass transition (Tg's) of the ester or ether soft segments
stree-softening temperature(Ts) and initial melting temperature(Tmh) of hard segment crystallites was observed.The result of cyclic testing of a constrained sample as a function of temperature indicated that the irreversible decrease in stress implied a permanent change in sample microstructure.
