本系列论文的第一部分和第三部分中提出的纺织品组件的粘弹性理论，应用于物理平衡过程（如老化和退火）后织物性能的实验研究。所研究的织物包括由羊毛和聚酯纤维以及羊毛/聚酯混纺制成的织物。利用自由体积概念分析了退火变量（温度、时间和回潮率）对织物粘弹性性能的影响。任何给定的退火条件下的织物应力松弛曲线可以从两个时移因子（一个取决于退火温度，另一个取决于退火时间）和织物应力松弛谱的知识来预测。利用时移因子构造了一系列主应力松弛曲线，从而为描述纺织材料的老化和退火行为提供了一种方便的手段。还对羊毛织物的老化性能和退火性能之间的关系进行了研究。结果表明，时效过程和退火过程具有相似的机理，退火过程可以看作是一种加速时效现象。
The theory of viscoelasticity of textile assemblies developed in Parts I and III of this series of papers is applied to an experimental study of the performance of fabrics after physical equilibration processes such as ageing and annealing. The fabrics studied include those produced from wool and polyester fibers and also wool/polyester blends. The effect of annealing variables (temperature, time, and regain) on the fabric visco-elastic performance has been analyzed using the free volume concept. The fabric stress relaxation curves for any given annealing conditions can be predicted from two time shift factors, one depending on annealing temperature and the other on annealing time, and the knowledge of the fabric stress relaxation spectrum. The time shift factors are used to construct a series of master stress relaxation curves, thus providing a convenient means of describing the ageing and annealing behavior of textile materials. The relationship between ageing and annealing performance has also been examined for wool fabrics. The results indicate that the ageing and annealing processes can both be considered in terms of similar mechanisms, and the annealing process may be regarded as an accelerated ageing phenomenon.
