Reducing the tension upon the fiber under high temperature to provide enough movement space for polyester segments, which is beneficial to the relaxation of high elastic strain.
适当地降低高温下纤维的张力，为高分子链段的运动提供了活动空间，有利于高弹形变的松弛。
2
Thequasi equilibrium relaxation occurs via elastic and inelastic scattering and the emission of longitudinal optical phonon.
通过弹性和非弹性的碰撞，发射纵波光学声子，半导体中发生准。
3
Prolonging the heat-setting time to provide enough relaxation time for high elastic strain, which can also reduce the inner stress and the dry heat-shrinkage.
