2) spring-back curvature
弹复曲率
1.
It is concluded that,in the course of stretch bending and straightening,the elastic district thickness is reduced by less than 3%,the decrement of the bending moment is proportional to the square of the tension,the spring-back curvature.
所得结论为,在与反弯矫直相同反弯曲率条件下,弹性区厚度略有减小,其减小量小于3%;弯矩减小量与拉应力平方成正比,其弹复曲率也相应减小;弯曲变形的弹复过程中,部分纤维处于塑性流动状态,弹复曲率和延伸量大于以往研究结果;若弯矩与拉力同步弹复,则弯矩与拉力弹复可按线性关系计算。

4) crimp recovery rate
卷曲弹性回复率
1.
As the tension of the heat treatment rose,the crimp frequency and the crimp radius of the monofilament went down,the crimp elongation rate went down,the crimp recovery rate and the crimp modulus of the monofilament and multifilament went up.
结果表明:随着热处理张力的增加,单丝的卷曲数和卷曲半径减小,单丝和复丝的卷曲伸长率减小,卷曲弹性回复率增加,卷曲模量增加;随着热处理温度的增加,单丝的卷曲数增加,卷曲半径减小,单丝和复丝的卷曲伸长率减小,卷曲弹性回复率增加,卷曲模量增加;在温度100～120℃且张力较小的条件下进行热处理时,PET/PTT纤维的单丝和复丝的卷曲弹性较好。
