padding: 0px; outline: 0px; max-width: 100%; font-size: 15px; overflow-wrap: break-word !important;">硬弹性纤维的变形和回复较弹性纤维有明显区别。例如硬弹性 PP 纤维经拉伸回复后立刻进行第二次拉伸，其模量和强度要下降很多，但如果去除应力后放置一段时间，或升高温度使其充分松弛后进行第二次拉伸，则其变形回复与第一次的曲线基本接近。这是由于该硬弹性纤维拉伸和回复时，不仅发生前述软弹性纤维卷缩分子长链段的拉伸和回缩变形，而且在拉伸过程中还伴随一些微孔结构的变化，它们的晶片网络结构也发生了变化。只有这些结构变化逐渐恢复后，才能回到原来的状态，故它们在较高压力下才发生变形回复，称为硬弹性纤维。</span></p></section><section style="margin: 0px;
