有两个因素对理解丝绸至关重要：纳米级的半晶折叠结构，它提供了高强度和特殊的韧性，以及无序部分的水化程度，这改变了这些材料的特性。这两个因素的组合允许有很大范围的机械性能。了解和控制这两个主要因素是蛋白质弹性体功能的关键，并使丝素成为(生物)材料设计的理想蛋白质模型。
Two factors are critical for understanding silks: the nanoscale semicrystalline folding structure, which gives high strength as well as exceptional toughness and the degree of hydration of the disordered fraction, which modifies these material properties. The combination of these two factor allows for a massive range of mechanical properties. Understanding and controlling these two principal factors are the key to the functionality of protein elastomers, and render silk an ideal model protein for (bio)material design.
