“传统”假设的纤维结构，例如流苏胶束和流苏原纤维形式，将纤维视为由结晶和非结晶区域的混合物组成。近年来，这种观点受到了相当多的批评，但它仍然是描述许多纤维特性的最有效基础。本文试图展示如何修改传统形式，例如通过引入链折叠，使它们与当前关于聚合物结晶的观点完全兼容。呈现了纤维结构的总体图，显示了如何使用各种极端形式（包括连续结晶、准晶和无定形结构以及双组分形式）来定义实际中可能出现的各种中间形式的边界。解释纤维特性的主要决定是选择哪种极端模型（必须是极端模型，以便易于定义和分析）在研究特定纤维行为的特定方面时最有用。讨论了羊毛、植物纤维、人造丝和合成纤维的机械性能。
The “traditional” assumed structures of fibers, such as the fringed micelle and fringed fibril forms, regard the fiber as made up of a mixture of crystalline and noncrystalline regions. This view has been subject to considerable criticism in recent years, but it does, nevertheless, remain the most effective basis for describing many fiber properties. This paper attempts to show how the traditional forms can be modified, for instance by the introduction of chain folding, so that they are entirely compatible with current views on polymer crystallization. An overall picture of fiber structure is presented showing how various extreme forms–including continuous crystalline, paracrystalline, and amorphous structures as well as the two-component forms–can be used to define the boundaries of a wide range of intermediate forms which are likely to occur in practice. The major decision in interpreting fiber properties is the choice of which extreme model–necessarily extreme in order to be susceptible to definition and analysis–is the most useful when studying a particular aspect of the behavior of a particular fiber. The mechanical properties, of wool, plant fibers, rayon, and synthetic fibers are discussed.
